Shopkeeper magnetism: 873 million yuan to pound heavily in solar market

By the positive news, July 26, shopkeeper magnetic (17.47,0.57,3.37%) (002,056) 18.59 yuan upward in order to limit the opening. The latest announcement, plans to invest 873 million yuan in Hengdian East magnetic crystalline solar park investment and construction of 300MW and 50MW silicon solar cell component project. Shopkeeper magnetism secretaries WU Xue-ping the "Securities Daily" correspondent said: "Although the market is expected to shrink the market next year, short-term overcapacity, fierce competition in the market saying, but we are optimistic about the prospects for the solar industry, the company began investing last year 100MW crystalline silicon solar cell production line, are now relatively smooth, good earnings. "

Main magnetic materials recovery

Large contribution to first-half profit

According to the shopkeeper magnetism July 6 announcement, the company expects in 2010 a quarterly net profit from January to June 2010, an increase of 100-140%. The estimated results are corrected for the 2010 first half net profit rose 130% -160%. Said, the overall warming of the economic situation this year, plus the company's management strengths, reduce costs, develop new markets, greatly enhance the revenue and net profit.

Deputy General Manager WU Xue-ping said: "The first half of the profits or the main contribution to large, but crystalline silicon solar cell production line quick, investment and output have three to four months, ended June 30, solar cell production line sales revenue of 8800 yuan, total profit of over 100 million. "

Great Wall Securities Yuexiong Wei introduced shopkeeper for domestic ferrite magnetic ferrite materials and leading manufacturers, market share of the first, which the world's first permanent production (in 2008 about 7.4 million tons), Soft production first (in 2008 about 2.6 million tons). 2008's ferrite permanent magnet and soft rice cake products in the country's market share was 16% and 10%. For the shopkeeper main magnetic ferrite magnetics products, Everbright Securities (16.27, -0.05, -0.31%), Zhao Lei that, globally, Ferrite Magnets higher degree of homogeneity of products, product prices with demand volatility, so the industry is a high flexibility. For style sound shopkeeper magnetism, the business should be to broaden the board of the chess.

Indeed, as Deputy General Manager WU Xue-ping said shopkeeper magnetism, the solar industry should be optimistic. The Chinese government in the "long-term renewable energy plan" put forward, solar photovoltaic power generation capacity by 2010 will be developed to 450MWp, while the installed capacity of solar power by 2005 only 6.5MWp, which means that the compound growth of China's solar energy capacity rate will be up to 38%, and "low-carbon economy" is that fossil fuels such as coal, oil, etc. to use as much as possible the use of biomass energy, wind energy, solar energy. New solar energy as a renewable energy, is considered to be the 21st century, one of the most important new energy, the development of a larger space.

Solar-oriented

See European "face."

Deputy General Manager WU Xue-ping, admits: "Our risk from those who we are later involved in, and now the scale is 100MW, 300MW to vote in, to 400MW." According to the announcement, 873 million yuan project will be fully operational 300MW per year production of crystalline silicon solar cells film and 50MW of solar modules production capacity, annual sales income of 3.1 billion, total profit 304 million. Shopkeeper magnetism gradually improved solar PV industry chain, related to the solar cells into the upstream and downstream products.

Shopkeeper magnetism related parties: "The company put into production lines in March and April, the third production line is expected to put into the third quarter, a total of five production lines." It is understood that the first solar cell production line started production in March, the current full load condition, the major suppliers of solar energy manufacturers in Zhejiang province, monthly income of 1,000 million, due to the beginning of the cost of inputs and scale advantages, low-margin, mass production after the current industry average net profit margin of about 10%.

Zhou Tao, the Great Wall Securities, said: "The solar industry profits volatile over the past few years, in 2009 also by the financial crisis, a quarter of a collective loss, some loss in Q2 because 96% of exports of solar panels, and mainly in Europe, if analysis of domestic solar energy companies, mainly to see the European market, while the euro exchange rate fluctuations, risks to the export-oriented enterprises. "Jun Ma, chief economist at Deutsche Bank, said central bank Deputy Governor Hu Xiaolian published a report entitled "managed floating exchange rate of three points," the article said the Chinese government to further promote market-oriented exchange rate formation mechanism reform, the determination and confidence. Because of the impact of exchange rate fluctuations, therefore, domestic production of solar panels will increase the company's future performance creates uncertainty. To export enterprises, to increase European demand uncertainty.

Donghai Securities predicted the electronics industry researcher Yuan Cheng, shopkeeper magnetism in 2010, 2011 and 2012 EPS was 0.55 yuan and 0.69 yuan and 0.86 yuan, based on company fundamentals and good future prospects for the development of new energy, to give 30 times 2012 PE, the target price 25.8 yuan.

However, the Great Wall Securities analyst Yuexiong Wei pointed out that "Although the shopkeeper magnetism 873 million yuan investment in the construction of 300MW crystalline silicon solar cells, etc., but with the current companies listed in the U.S., Suntech, LDK, in comparison, there are still a gap. "This is to be the company secretaries to WU Xue-ping said: the company's risk from those who he is later involved.

Beautiful first-half performance of photovoltaic polycrystalline silicon business in the second half, "Warrington"

2011-09-13T20:47:00.001-07:00

Beautiful first-half performance of photovoltaic polycrystalline silicon business in the second half, "Warrington"

According to Wind Statistics, as of July 22, the concept of domestic PV 47 listed companies to disclose results of the first half of this year, 26 Express or forecast, of which forecasted up to 21 companies, accounting for 80% .

Analysts said the first half of the growth performance of the enterprises are silicon photovoltaic or battery business, because the first half of the low cost of the product price has been lifted. With the price of polysilicon this year, rebounded in July, is expected in the second half, especially high purity polycrystalline silicon polysilicon manufacturers market is about to come.

First to benefit middle and lower market rebound

It is understood that, since March of this year, the international PV market showed a continued warming trend, solar wafers, cells of different degrees of price rise, which in March, prices rose as high as 20%.

Many downstream manufacturers of photovoltaic surprised to find that in polysilicon prices continued to slump at the same time, the price of photovoltaic products a certain level of recovery in the first half of this year's performance and gross margin are expected than expected. LDK official said, the international PV market to pick up orders will continue to support the full battery of silicon, while the price has improved, multiple factors favor the performance of the company's performance.

Data show that the first half of forecasted PV 21 listed companies, CSG A first half net profit of 636 million yuan, an increase of 143.51%. Dah Sing the first half of the new material is expected to net profit of 65 million -7200 million, up 126% -150%.

International agencies have forecast estimates that by 2010 the global solar market will reach 12.2GWp scale. Solar Energy solar market in 2010 to calculate the amount of approximately $ 30 billion.

A good international environment for domestic solar companies to eat "assurance", and some companies began to expand production at the same time, the market will attract more investors to enter.

Industry experts optimistic about the photovoltaic industry boom of the second half, second half of 2010 or 2011 will be officially launched economies of scale and vertical integration of the competition.

Polysilicon in the second half bullish

In the photovoltaic industry chain downstream products rose a certain extent, the market began to pick up the trend of raw materials delivered to the PV industry polysilicon. July of this year, there is a clear international polysilicon prices rose. Polysilicon prices have 50-52 dollars / kg up to 60-65 dollars / kg.

A domestic PV manufacturers that the PV device market now than in 2008, expanding at nearly double the polysilicon production capacity to expand up to more than 50% in 2008, this year the whole industry full of photovoltaic industry production, by the PV industry and semiconductor Industrial demand-pull double polysilicon supply and demand situation is tight again.

The second half of this year, the scarcity of high-quality production capacity will support the corresponding prices. LDK official said, is expected to purchase polysilicon from the company's point of view, high-purity polysilicon shortage is already evident signs of expected short term is unlikely to change this situation. First-tier manufacturers in many industries expect polysilicon prices will gradually rise to 70-80 dollars / kg.

At the same time, for wafers, cells, components suppliers, because polysilicon prices, "low cost, the price rise," the good times end, the industry worried about the second half of the cost pressure. The polysilicon producers in the second half due to tight supply and demand and the harvest may be a better performance.

It is understood that in the first half the price of polysilicon in the doldrums, Xinguang output of the first quarter of 2010, only 180 tons, up by 23.88%, loss of 23.71 million yuan. Polysilicon prices to regain the recent rally, the second half to help Xinguang rebound performance.

But some analysts believe that, because of China's polysilicon production capacity surplus last year of the shadow, the overall price of polysilicon is expected to rise sharply unlikely. And many manufacturers of photovoltaic River also said if the rate of rising costs too, is bound to further downstream transmission.

Solar-cell factory at the end of the second half of the rise and fall offer into key operational

2011-09-09T00:06:00.000-07:00

Solar-cell factory at the end of the second half of the rise and fall offer into key operational

German solar subsidy announced that the latest case, the solar industry believes that actual demand will start in Germany, the most worthy of observation that is the price trend in July, once the price is not so down, over the end of July, the majority of companies believe that the price of solar is unlikely to again bargain, solar-cell factory in the second half is expected to sit back and relax. However, if the price appears loose in mid-July, the economy's trend will test a low quarter by quarter.

Previously by the Bank can not estimate the rate of lead lending freeze, and the investment rate of return (IRR) and difficult to estimate the system case of delay, all because of expectations of the new German assistance was announced after the official launch, the solar industry said that the July price trend will also be a reference to the most important indicator of the second half.

Solar industry said that the European market in the most mature of the German solar industry supply chain influence high in Germany to launch a new subsidy cases before the majority of German industry is actively towards non-German system market, but still retains a considerable inventory ratio, followed by Germany's decision to wait after a new case to complement the operation, which also includes a number of international module plant in Germany, large warehouses, waiting till after the case was sold in Germany.

Once in Germany under the third quarter after cutting 13% of the subsidy rates, market demand in Germany fell more sharply than expected, estimated German industry and within the international plant inventory positions, will be forced down to non-German stock market to reduce inventory This will lead to an overall impact on the market again, especially some quotes, I am afraid to face the impact of a single grab bargain.

Once the price started to decline in July, the price estimated in the second half will follow continued to decline. While Germany will be cut in the fourth quarter, 16% lower subsidy rates, but rates for the third quarter with only a difference of 3 percentage points, if prices continue to fall, then consumers will have expectations, after all, prices decline follow the installation costs down enough to make up for season 3 and 4 the gap between the subsidy, which will lead to the actual needs of the action falls in the fourth quarter.

However, if the demand spread to Germany than to imagine a small, German industry without strong inroads into non-German system market, or non-German market is in fact a considerable amount of appetite enough to absorb the fall of German industry goods, grab a single, multi-supply and demand in the adjustments, so that prices will remain the some stability.

Solar industry analysis, the current price level, if you can last until the end of July, the probability estimates in the second half again haggling is not high, because the market adjustment mechanism is an effective response to the current price level has been able to light up market share 5 percent of the German market after the subsidies cut under the impact, people expect falling prices is difficult psychological health, but also must consider the fourth quarter to cut 16 percent subsidy on the next, hoping to take action to install the very high government subsidies chances will increase. 4 quarters battery industry to "sit back and relax", no longer worried about price competition issues.

Taiwan-based industry, including Motech, Yu Jing, Sun Division, new solar, and other benefits through, part of the solar cell factory in the third quarter from the spot market price per watt in the second quarter jumped to $ 1.4 $ 1.35 or more, mainly due to from Taiwan-based solar cell industry by non-German markets, including Italy, France, Czech Republic District orders blessing, the recent release of Japanese single most obvious Outsourcing orders.

Changxing County built three walls of the battery industry

2011-09-04T20:02:00.000-07:00

Changxing County built three walls of the battery industry

Changxing County, Zhejiang Province, in five years, basically a battery of intensive industrial development, in one fell swoop remove the "key regulators of the provincial environmental protection zone" hat. This is the Changxing County based environmental protection, pushing the "Forced" mechanism achieved a magnificent turn.

Based on sustainable development, environmentally friendly, leading the industry to enhance

Changxing battery industry first started in the 1970s. Rapid development in the battery industry, on the road, Changxing County, once stepped into the extensive development of the "quagmire." In 2004, Changxing County, is listed as "key provincial environment monitoring area"; August 2005, Changxing County, shocked the province took place in the "days to the event."

The industry should not develop? How to develop? For when someone's put all of these polluters off the proposal, Changxing county, the county government after repeated consideration, to make their own judgments. Party Secretary Liu Guofu that: the battery is Changxing's traditional industries, development potential, we can not simply shut up, the key is to strengthen environmental protection, so that the industry develop more standardized and improve production processes. So, in 2006, Changxing County, development and reform, environmental protection, health and other six departments commissioned the College of Environmental Sciences and Geography Research Center of Peking University developed a "Green Power Energy, Zhejiang Changxing County development strategy planning center" and related implementation advice, and strive to Changxing battery industry to build a production capacity, technology, research and development, the national first-class cluster, and both environmental protection and recycling economy, social harmony and other characteristics of the international regional centers.

5 years, from companies shut down, to carry out treatment, to upgrade and Changxing battery industry a new look, a number of battery companies have national and even international leader in products and technologies to drive the entire industry.

The formation of environmental Forced mechanism, promote industrial restructuring and upgrading

Environmental protection "Forced" mechanism is to promote Changxing powerful battery industry reborn promoter. Changxing County Environmental Protection Agency from the pollutant discharge standards and total control, project access, strengthen the regulatory side of face and so stopped the "wall", the original "black cell" step by step toward a "Green Battery" development road .

Although electric vehicles travel is green, but lead-acid battery manufacturing process will produce smoke of lead, lead dust, mist and other pollution. Changxing County initially focus on industrial pollution discharge standards and total control, strict elimination mechanism through the development and financial incentives from the first block "wall." Changxing County in order to "close down a number, specification number, to enhance the number of" for the general idea of the various county survey 175 companies to start to form a battery special work program. At the same time the introduction of policies on environmental protection through the acceptance of the company, given the amount of equipment investment bonus of 4%; on the voluntary application within the specified time cut-off companies, to give 10,000 yuan to 5 million in subsidies; on the transformation of production equipment, improve production technology, improve product quality, and give some encouragement. 2009, Changxing County, battery dropped to 50 the number of enterprises.

"In the past, what food we eat; now to look at a meal, the enterprise re-understanding of those environmental hazards will not eat big." Liu Jin Changxing County Environmental Protection Bureau, said with emotion. Changxing County Environmental Protection Agency approval of the project to improve the access threshold for the industry to optimize the development and build a second "wall." "Accelerate the construction of the implementation of China Green Power Energy Centre (Trial)", the clear all battery manufacturers for new construction, expansion, renovation, transformation projects are the development of technical equipment, environmental protection and occupational health access standards in three areas; in the environment access standards, and assembly of the battery plate production companies and the production equipment, production processes and pollutant discharge standards and pollution control programs to make specific provisions.

The third "wall" of the build is to strengthen the environment by continuously monitoring. Changxing County Development and Reform Commission, Environmental Protection Agency and other 8 departments to establish a joint management mechanism for the battery business, which the county Environmental Protection Agency requires environmental monitoring for one year the battery at least once a company from time to time supervisory monitoring, pollution control facilities for business operation, the excessive discharge and ordered to enterprise investigation and rectification; the other on a regular basis to monitor the environment around the battery business, dynamic control and timely evaluation of the surrounding environmental conditions. Currently, 60 percent of Changxing County, installation of on-line monitoring of the battery business facilities and networking with the county Environmental Protection Agency.

2009 compared to 2004, Changxing County, the battery business of heavy metals emissions of total lead cut 3 / 4, output has increased by nearly 5-fold.

Pressure more motivated to promote the development of transformation and upgrading

"Forced" to today's Changxing battery enterprises, have not only the external pressure, is intrinsic motivation. Because the reality that businesses understand that only the good of the environment in order to do business.

Group in Zhejiang Jiang Chaowei reporter battery production plant to see the production line was automated, semi-automatic state, the production process of lead dust, lead powder is a huge pipeline to take away the root and then to focus on disposal. Today, the company found a new development: do solar streetlight system storage batteries. It is reported that the price of a storage battery at least twice the price of conventional lead-acid batteries and more. General Manager Wang believed that the most important reason is that this industry, both environmentally friendly and innovative, more competitive in the future vitality. It is reported that a number of nickel-metal hydride, lithium ion, silica and other next-generation low-carbon energy battery has started to market from the Eternal.

The end of 2008, Changxing County to support local environmental protection department and the introduction of the Fortune 500 companies - "Johnson Controls." This production of automotive lead-acid batteries, a one-time investment for environmental protection equipment on the $ 10 million, and in its 43,000 square meters of the giant micro-negative pressure room means to prevent the production of lead powder, Lead dust outflow. Faced with this world-class strong opponents, so that local colleagues felt the pressure of competition, prompting them to work harder to environmental protection.

ULVAC market thin film silicon solar battery automatic detection device

2011-08-30T01:33:00.001-07:00

ULVAC market thin film silicon solar battery automatic detection device

Japan's ULVAC (ULVAC) announced, will be July 1, 2010 can automatically detect the series listed on thin-film silicon (Si) solar cell characteristics and TCO (Transparent Conductive Oxide) characteristics of the device "MPEC-opt1300". The company overall solution (Turn-Key Solution, to provide complete line of solar cells produced) as the center of business, which was launched in 2009 that can detect six kinds of thin film properties of a body unit "MPEC-1300". In addition to the membranous detection device outside, this also launched a unit automatically detects the device and TCO characteristics.

The production line of products for purposes of sampling inspection, can undermine the inspection unit features (shunt resistance and some other features can be non-destructive way to check), TCO properties can be checked separately by non-destructive testing. In solar cell production line after the performance evaluation process and final product inspection (solar simulator) used to resolve the problems found and reasons. As an option, but also with the results according to shunt resistor (resistor bad location information) of the laser repair, as well as the existing MPEC-1300 and the detection of MPEC-opt1300 unified data "Comprehensive analysis software . "

Features in the unit, originally from the formation of solar cells under the glass floor in the cut about 5mm square, to impose through its tin solder and insulate the electrode to produce called "mini-unit (Mini Cell)" a small piece components, then using irradiation or exposure to the elements the way of light, and features of the IV test. However, the formation of mini cell requires a lot of manual processing, and processing time is longer. ULVAC, said the original glass in the cutting needs of 180 seconds per point, per-point soldering, 300 seconds per test point to 75 seconds, such as 81-point test requires 750 minutes, 7 test takes 65 minutes.

And the device can not cut case of glass substrate, glass substrate using laser film formed on the silicon layer to be cut to form a mini-unit. As a result, the laser cutting each point only 30 seconds per test point just 40 seconds, in order to achieve a 81-point test requires 95 minutes, 7 points 7 minutes of the short detection test. Detailed characteristics of the unit test project, the conversion efficiency can short-circuit current, open circuit voltage, field shape factor, maximum power, shunt resistance and series resistance were detected.

In the TCO properties, the original need for cutting the glass floor of the damage inspection, and the device can be non-destructive way by a large area of haze characteristics (the ratio of scattered light) distribution for testing. Moreover, the detection time point only every 30 seconds. Defog degree features, it can also detect all the light transmission rate, diffusion rate and the parallel light transmittance transmittance. The unit price of 84 million yen (option). ULVAC will provide a package of solutions, the company's solar cell manufacturers as the main object, expand sales.

Existing MPEC-1300 has negotiated five or so orders, of which Taiwan will soon have a supply. The development of the MPEC-opt1300 also the first five year sales target. The goal "is a conservative estimate of thin-film solar cell manufacturers may also give priority to the flat panel display (FPD) and the crystalline solar cell investment, and defer investment in thin-film solar cells, so there may be a part of Taichung will be 5 next year in sales." (ULVAC Standard Products Division, East Japan Sales Minister Takeda clear).

Sony battery out of the behind the scenes appeared CIBF

Changxing sounded well-being of the battery industry, "assembly"

53 battery business, "Health Cup" Story

From Changxing County in the car driving to the coal town on the road, threw herself out the window from time to time to pass the eye of a huge billboard with a message: This is the gathering place of the battery business.

June 17, Changxing County, "Safety Month" an important event scheduled for this day, the county 53 days of battery companies in Zhejiang Energy Group held on the spot, in addition to "focus on security, health care," thousands of signatures which shocking scene, the county's battery industry, "Health Cup" contest will be this summer. Changxing County Federation of Trade Unions President Zhou Boshun that this time we do the battery industry, "Health Cup" competition full coverage.

Speaking of the battery industry, there had been no glory in the Eternal past. In 2005, it has happened in the days to group together mass incidents, when a few people use coal town on corporate environmental demands of the masses, inciting illegal, disrupt the lives of local people's production and economic and social order. After that, the local party committee and government adopted a series of measures, especially in early 2007, Changxing County, the introduction of the new township assessment methods, and clearly defined eco-counties' vote veto ", the same year, due to wear a lead-acid battery industry for nearly two years at the provincial level, "key environmental protection surveillance zone" and "hat" were cast off.

Based on this background, the battery industry, carry out a comprehensive "Health Cup" contest has a special significance. Provincial Union Minister Huang Mengyue that labor protection, at the county level, the main line to carry out an industry, "Health Cup" contest, and chose a "criminal record" of the battery industry is undoubtedly useful to explore.

In this regard, Changxing County Federation of Trade Unions President Zhou Boshun told reporters, after several years of development, the battery has become the pillar industry of Changxing County, and is undergoing a transformation and upgrading of the critical period from the time of the node point of view, in full industry to carry out "Health Cup" contest conditions are ripe. This is the "Uncap" after another "to upgrade", it will face the industry, safety of long-term mechanism.

"Days" to complete in five years turned gorgeous

In the "Health Cup" competition at the scene, "days" Chen Min, vice president of flower business for 20 minutes to introduce safety of the status quo. Including a set of data to allow participants to marvel: In 2007, the cost of work-related injuries for workers is 53 million yuan in 2009 this cost down to $ 80,000, the first half of this cost is down to 8,000 yuan, but also for major traffic accidents occurred in the class of injuries outside the company.

5 years ago, was once a hair-trigger "crater", as it is today to the company among the "Health Cup" winning unit of the provincial ranks. "Days" that turn called gorgeous.

Enterprises from the "labor pains" in the way, workers feel is the most real. In "days" 11 years of working for Jiang Shuo Fang witnessed this transformation, she is more willing to use details to describe her feelings. Jiang Shuo Fang first described to reporters the details of a "bath." Part of the battery industry, operating in front-line employees are exposed to lead in the past, a time to work, the workers hurried home, especially female workers, home cook to cook, take care of children. Potential risk is the risk back home. The company in recent years under a "dead order": exposure to toxic and hazardous substances workers must shower before changing to go home. "In the beginning workers do not understand, this measure is almost mandatory, staff developed a habit now, understand that the business is responsible for the health of themselves and their families."

Jiang Shuo Fang described to reporters the details of the second is the "mask", front-line workers to wear dust masks that induction is not surprising, but what to wear a mask without affecting the operation the best, and perhaps very few companies will seriously consider. "Days" approach is to try, try not only front-line workers, middle managers have to try to take the lead. Today, the company selected a gas mask, twenty-three days to be replaced a filter paper, which is a thin filter paper price is twenty-three yuan, only this small masks, spending a year in the company 20 million yuan .

"Health Cup" campaign embodies the essence of caring for employees, the company's wall space is not as care line. "Days" assembly plant B workers Hu Junfeng, told reporters in the "days", right hand guard is not really small. Many company employees ride to work the car battery, the company's management to guard a "power", no license, battery cars are not allowed to enter the factory workers, not wearing a helmet riding a cable car guard was found, it will inform the employee's department, not only is a trade union, as well as employee's department head must have been "guilt" punishment. "Days" of the "guilt" system is very strict, if the production safety accidents occurred, then this line director, supervisor, team leader, as well as the responsibility of the security sector stakeholders who have run away, the company's management have to say are: safety no room for bargaining.

In fact, for safety, the sound system, policy and can not explain everything, the key lies in execution. In this regard, employees feel the deepest, most have a say. In order to examine the "days" of gorgeous, everything would come out ahead.

10 100% open with confidence

"Days" of gorgeous, is a touch. Despite the ugly past, out of the shadows is entirely possible. In Changxing County, "Health Cup" competition organizing committee for the implementation of tailored views of the battery industry, the reporter saw 10 to 100% Description: It should be lessons learned lessons from the accident is 100%, should be familiar with and master the safety of knowledge is 100% control, should be the induction of new workers is 100% safe for education and training, should be dispensed if the labor protection supplies 100% of the allotment ... ...

Demanding work, reflects a confidence. Changxing County Federation of Trade Unions President Zhou Boshun that Changxing confidence to rely on the battery industry has made great progress, and now carry out a comprehensive "Health Cup" competition in practice, the first still is confidence.

"'Health Cup' to promote the development of enterprises." This is the "days" as Chen Min, vice president of the words from others. In the "days", where many workers have done in 1989 or even 10 years, and some are even in the company to work with families of children with Jiang Shuo Fang's words, workers in the "days" to work feel at ease, feeling confident. The confidence of employees from the business confidence, with confidence are not any insurmountable difficulties.

Security and development, it means businesses can secure a better development. Changxing battery industry practice to use the next few years to prove this truth.

Scientists develop new types of carbon nanotubes a tenfold increase in battery life

As smart phones in the functional aspects of the advances, battery life, and life has become increasingly unable to meet the needs of users. Smart phone users have complained that the mobile power capacity as a child, like the rapid consumption of candy. Currently, a new rechargeable batteries in portable electronic products manufacturing technology to solve this problem to bring the dawn of the new manufacturing technology created by the battery power to build ten times the current battery.

MIT scientists have discovered large end of the battery electrodes containing carbon nanotubes can be more than the current lithium Xucun power. Scientists in the lab using multi-cathode cell with carbon nanotubes, using lithium battery anode manufacture of titanium oxide. This battery charging efficiency and storage capacity than most high-end lithium batteries better. With carbon nanotubes in order to verify the performance of the battery service life, scientists developed a new battery with carbon nanotubes 1000 charge-discharge experiments. After 1000 the results of charging and discharging, the battery with carbon nanotubes within the material properties change very little battery power did build unabated. This also shows that carbon nanotubes than the lithium batteries have a longer life.

For the use of smart phones and other portable electronic products, users, this is good news. But this battery with carbon nanotubes is still only at the laboratory research and development stage. Constraints of this new popularity is largely due to the battery, the battery is made with carbon nanotubes in the electrode substrate before the batteries need to dissolve in two different soaking liquid, and this process is extremely time consuming. MIT professor of chemical engineering major Paula - Hammond (Paula Hammond) claimed that her research team are currently working to find a solution to this problem. Currently the most viable solution proposed for the substrate with carbon nanotubes by spray to replace the irreplaceable material in the cell lysate in the soaking time-consuming process.

Believe that this battery is made with carbon nanotubes in the near future can be listed, then the use of smart phone users will no longer need enough power for mobile phones and other problems bother.

Three quarters of German solar cells offer the industry's first match that the two sides

Although both sides offer solar cell factory in the third quarter and second quarter remained fairly flat, but by the euro's benefits, the solar market spread, the German first-line solar cell factory has resorted to in the third quarter of the battery price per watt expected to price 1.1 euros, converted into dollars, and the two sides offer very close to the industry, may be 2004 since the rapid growth of the PV industry, first to see "close quote," still waiting for the market shockwaves.

Depreciation of the euro and by July 1, Kusakabe German solar subsidy rates cut not clarified the impact of the German market in addition to the module industry in the third quarter under notice will cut 10% of the price, recently, a line of German solar-cell factory also reposition itself in the third quarter will be lower price strategy.

Solar industry said that although the plant for the front-line solar-cell factory, but usually the price level is not high-priced range, the current price per watt of battery about 1.2 euros, but in the third quarter came to an estimated ~ 1.1 euros offer an average reduction of 8 %.

The German front-line factory price decline is not, but 1 to 1.1 euros converted into U.S. dollars about $ 1.23 - $ 1.35, in fact, offer has been with the first quarter of Taiwan-based industry spot market price $ 1.35 per watt, rather, may be the sun in 2004 Since the rapid growth of the optoelectronics industry, European solar industry representative quoted rare so close to Asian businesses, particularly the two sides is almost equal to the price of solar cell industry.

Solar industry said that the European system operators benefit from the euro because of the impact, so the price is relatively competitive, but rather because of limited cross industry pressure on the euro, the price cuts have not been able to make it past the the most competitive price advantage resulting passivation, no doubt for the two sides still sit on the sidelines shockwaves through the industry.

Germany under the cut subsidies, the supply chain does move outside the seemingly passive price-competitive Asian district? Solar industry that this trend is no doubt, because the German industry is also a way to reduce production capacity in Europe, and actively the production lines to Asia, and a considerable proportion of the industry from mainland China for OEM production, currently appears to be benefiting from exchange rate fluctuations, resorted to low-cost strategy.

European system of solar energy systems plant frankly, as German factory price has always been more than two sides industry is high, orders will flow to Asia, in the third quarter if the German factory price down to and cross industry rather, it will make a lot of European Department of the module and system Factory can not accept, the flow of orders expected in Europe will also have changed.

Department of solar-cell factory in Europe, including Germany Q-Cells, Solarworld, Schottensolar, Schottsolar, etc. In fact, many industry-based layout to vertical integration, while Taiwan-based battery factory, most of the professional factory including Motech, Yu Jing, solar and other new, continental vertical integrated plant, including Suntech, Yingli, Trina Solar, Solarfun, JA and so on.

Electric vehicle battery recycling new energy electrical storage precautions

People often complain that although the life you want to become better environmental protection, but the cost is too high. For plug-in hybrid and all-electric car, the price they do a lot of money, because the cost of electric vehicles using lithium batteries high. How to protect electric vehicle performance while reducing power car cost? Ontario, Canada, manufacturer of lithium battery developer Electrovaya's staff (Sankar Das Gupta), said he found a way to reduce battery costs.

Used batteries "born again"

Reduce the cost of electric cars using one of the ways is to make vehicles to the grid. Currently, there are many power companies and manufacturers of electric cars began to study how to use the vehicle parked in the garage charging time, so as to save electricity grid. Of course, this is based on the electric car owners access to capital subsidies and other incentives based on.

However, the use of electric cars have a power grid electrical storage drawbacks, namely the frequent additional charge and discharge will reduce battery life, especially if people just spent $ 40,000 to buy a new car, no matter how much allowance to give, it is difficult to convince owners of an estimated Take car batteries to charge storage. (1 U.S. dollar equals 6.83 yuan)

Electrovaya's Gupta believes that the idea of electric cars into the grid may be better achieved. He said that although the old lithium battery electric vehicle charging hard to reach saturation, to meet the exercise needs, but it can use its power grid electrical storage.

Currently electric car industry in general that can only be filled once the old original battery capacity of 80% of the electricity when the battery can be declared "end" of the. And Gupta, in fact, that only 80% of full power to use the old battery as the battery power is very appropriate. Gupta to promote recycling of used batteries, its access network.

Electrovaya is currently working with the University of Manitoba, Canada (University of Manitoba) to study how to combine lithium batteries used to build a prototype power up to 150 kWh of electrical storage systems, and monitor the storage system in the access network When running performance.

New energy electrical storage precautions

There is a growing supply of future energy hopes on wind, solar and other intermittent power sources, the power savings become increasingly important. Intermittent power sources can not control the gate to meet the demand, only charge storage to ensure extra power is not wasted; and even if the wind or the sun disappeared, power storage and will not cause the power supply interruption. Power companies and researchers have been trying to solve the intermittent energy generation power storage methods, such as using compressed air energy storage wheel and so on.

University of California, Berkeley Transportation Sustainability Research Center, Brett Williams (Brett Williams) said that the use of secondary lithium battery electric vehicles the equivalent of two birds with one stone: on the one hand compensates for the cost of the battery electric car owners, it also makes available renewable energy product manufacturers benefit.

Williams believes that recycling of lithium batteries for energy companies may be more attractive, rather than outsourcing the work to the various power-storage owners in their own charging electrical storage. He said: "static (electric car battery power storage) devices connected to the grid all day, ready to meet demand."

Universal battery technology to develop depth

According to reports: Recently, a wholly-owned subsidiary of Universal Group, Universal Electric Motors and the United States Ener1's battery and battery system on the joint venture signed a framework agreement.

It is understood that Universal Electric Motor Company is the leader in the field of electric vehicles, since 1999 the development of electric vehicles and their key components, is 863 pure electric vehicle powertrain technology platform project undertaker. Universal electric car is the 2010 Shanghai World Expo the largest electric vehicle parts supplier, also the 2010 Guangzhou Asian Games only a pure electric vehicle parts suppliers. Ener1, a U.S. NASDAQ listed company, focused on the battery and fuel cell business, the U.S. Department of Energy and the U.S. Advanced Battery Consortium identified six core supplier of electric vehicle battery, the battery group technology at the international advanced level.

The signing of the framework agreement, Universal electric vehicle with Ener1's in Hangzhou, China to establish a fully automated system of batteries and battery production base, the first phase investment of 300 million U.S. dollars, is expected to form the end of 2011, when 300 million security 40,000 sets of batteries and battery systems for electric vehicle production capacity. Cooperation with Ener1, universal lithium ion battery business will be more quickly into the international face of the electric vehicle industry opportunities and challenges in technology to enhance the international level will obtain the simultaneous development of the capacity for rapid development into the electric vehicle battery market to create more opportunities.

2011-08-19T01:37:00.000-07:00

To be more civil with solar wind and other renewable energy

As a "big power" of various types of civil Ningbo - including residential construction, the state organ office buildings and commercial, services, education, health and other public buildings, the construction process from starting August 1 this year by the energy constraints of the new regulations. Ningbo Construction Committee announced yesterday that, "Ningbo Energy conservation measures" has been the municipal executive session; under the new rules, if the new civil construction completion and acceptance or no acceptance of unsatisfactory energy, will not be allowed into use .

Three types of building energy efficiency project will not fail

New regulations require construction drawings must comply with the mandatory energy efficiency standards and report to civil construction administrative departments for the record, otherwise it will not get construction permits, construction not started. While the new regulation stipulates that any unit or individual may change after review of the record of the construction design documents, shall not reduce the building energy efficiency standards.

As a "big power" in the "big", the new regulations for the three types of civil construction - single building area of 20,000 square meters of public construction projects, construction area of 200,000 square meters of residential construction projects, a single body building area of 10,000 square meters of government investment projects, and made more stringent energy constraints. These three projects in the approval, approval must accept the relevant departments of the energy assessment, energy review to get approval if not advice, it will not project.

Civil construction projects approved construction or sale, according to new regulatory requirements, construction units, real estate development enterprises shall, respectively, in housing construction and sales (pre-) field publicity civil energy information, energy-saving measures expressly housing, insulation works warranty and other information. Should also be accurately loaded real estate sale, residential or residential quality assurance manual.

In the meet the energy requirements of buildings put into use, in accordance with the provisions of the new regulations, the building owner or right to use, without changing the building envelope, and where changes should be reviewed by the original design unit shall not reduce the building consent and materials for energy efficiency.

Encourage the construction of renewable energy technologies

New regulations also encourage civil construction, the city focused on promoting the application of solar thermal, solar photovoltaic, solar lighting, ground source heat pump, water pump, wind power and other renewable energy technologies.

Among them, new hot water systems are public buildings, 12-storey residential buildings and 12 floors above the inverse six-story residential building, shall be integrated solar energy and building design. Government investment and financing of civil construction projects, and new construction area of 20,000 square meters of shopping centers, hotels, hospitals and other public buildings, you should at least use a renewable energy, and opinions issued by experts.

In addition, centralized air conditioning system, a stable demand for hot water and building area of 10,000 square meters of new construction, renovation, expansion of public buildings, the new regulations encourage the design and installation of air conditioning waste heat recovery unit.

Does not truthfully provide the building energy consumption to be punished

In accordance with new regulations, administrative department of construction of Ningbo City will establish a platform for civil energy monitoring, periodic evaluation of building energy consumption statistics and analysis, and heating, cooling, lighting energy consumption according to relevant regulations to the public.

State organ office buildings and large public buildings, the owner, the right to use, regular use can transmit data to the civil power consumption monitoring platform. Building owners, the right to use people or property services companies, if not truthfully provide building energy consumption, or unjustified obstruction of solar and other renewable energy, will be ordered to make corrections and be punished.

Ningbo Construction Committee, according to the person in charge in 2005 after the civil construction of the city, have been mandatory at 50% energy saving design standard design. But research shows that current energy consumption of residential buildings in Ningbo (mainly electricity situation) is relatively low, but the hotels, shopping malls, office buildings and other residential building energy consumption is 10 times -20 times. At present, Ningbo City, the community building energy consumption accounts for about 25% of total energy consumption to 30%.

All levels have paid attention to the development of new energy automotive industry

To hybrid, plug-in hybrid and pure electric vehicles as the main driving force way of new energy vehicle development strategy has become the industry consensus, at the various countries, major companies, and related systems in order to seize the commanding heights of industry efforts, relevant investment policy, consumer subsidies, tax incentives began to put in place. Development of new energy vehicles in China are high hopes, at all levels attach great importance to the development of new energy automotive industry, is also very optimistic about the future of new energy vehicles, and even optimistic about their "turn overtaking" the prospect of occupation of the global industrial power lithium battery is facing a huge market opportunity high ground.

Battery

Electric car industry the most critical link in the chain

New energy vehicles in the traditional auto industry chain based on the extension increases the battery, motor, electric control system components. Battery is new energy automotive industry chain is one of the most critical link. There Ouqi in pure electric vehicle, battery performance determines the vehicle speed and driving range, the stability of the battery determines the vehicle's safety and reliability.

Electric vehicle electric drive system is mainly composed of: battery (including the battery management system, charging system), inverters, drive motors (including motor speed control system). Depends on advances in battery technology and other basic disciplines of materials science advances, technological breakthroughs difficult, but the promotion of electric vehicles is dependent on battery cost has dropped significantly. Lithium-ion battery energy density is about 1.5-2.5 times the nickel-metal hydride batteries for lead-acid batteries 3-5 times since the index discharge was significantly better than nickel-metal hydride batteries, lithium-ion battery electric vehicle battery will become the main technology routes .

Promotion of electric vehicles will increase demand for raw materials downstream. Lithium-ion batteries are four main raw materials include: anode, cathode, electrolyte, separator. Cathode due to the different materials, manufacturing costs account for about 30-40%, negative material about 15-20%, accounting for 15-20% diaphragm, electrolyte 5-10%, about 25% of other costs. Pacific Securities electric car by 2020 China is expected to total car sales of about 5.4%, PHEV is expected to become a major component of electric vehicles in 2020, accounting for 4.5% of total car sales.

Lithium battery

Faced with tremendous market opportunity

Battery is new energy automotive industry chain technically demanding, high degree of concern of part of the cell area has a long-term competitive advantage in business is expected to become the new energy automotive industry a good investment targets. From the current situation for hybrid cars Ni-MH battery commercialization in the next 3-5 years, more likely, mainstream companies are now NiMH batteries to major OEMs in the trial, such as the ability to form small quantities, will be central to its earnings expectations and valuation greater increase. For pure electric cars lithium iron phosphate is expected to become long-term development.

According to relevant aspects of Japan forecasts that by 2015, global HEV (a hybrid device), hybrid source [8.88 0.57%] electric car according to the main form of energy into the synthesis of tandem (SHEV) and parallel (PHEV) two. PHEV and EV sales will account for 13% of the total, 2020 this figure will reach 26%. Great Wall Securities predicted that by 2015 the new energy vehicles will reach ten million production and sales levels, which accounts for the main part of the HEV and PHEV, the cathode material in the corresponding demand exceeds 250,000 tons. Taking into account the new energy bus, sightseeing cars, yachts and other needs, will re-power lithium batteries a huge market opportunity significantly related industries.

Within the overall policy, the Government's support for the direction of plug-in hybrid vehicles and pure electric vehicles, TX Irving that the main benefit to the industry chain of lithium iron phosphate as cathode of lithium battery industry chain and related areas to benefit including automobile companies, charging equipment companies, focusing on listed companies, including: lithium battery management system, lithium battery, lithium battery cathode material, lithium battery cathode material, lithium electrolyte, lithium battery separator.

New energy vehicles investment strategies: the first lithium-powered vehicle

2011-08-15T00:56:00.000-07:00

New energy vehicles investment strategies: the first lithium-powered vehicle

June 1, Ministry of Finance, Ministry of Science, the Ministry, the National Development and Reform Commission jointly issued a "new energy vehicles to carry out subsidies for private pilot," which determine in Shanghai, Changchun, Shenzhen, Hangzhou, Hefei, 5 cities Start the private purchase of new vehicles to subsidize pilot energy to show the state's new energy policy to support efforts to increase the car.

Brokerage analysts, lithium chemical companies will directly benefit from the promotion of new energy vehicles, and vehicle probably needs to be further investment in the company to wait for the right time.

Lithium chemical companies benefit

State subsidies of this plug-in hybrid electric passenger cars and passenger cars are basically the use of lithium-ion battery, so that the Changjiang Securities, lithium chemicals, the company's future will benefit.

Changjiang Securities report provided that the electrolyte side, Fluoride is expected to realize lithium hexafluorophosphate localization, to break the Japanese three companies of the product monopoly; electrolyte, take the high-end line of the new chou and Jiangsu Guotai will benefit; positive materials, when the rise of science and technology prospects.

Changjiang Securities, especially recommended for Fluoride. According to reports, Fluoride is the current lithium hexafluorophosphate closest to the industrialization of the company, its products once the market will break the current oligopoly structure, truly lithium hexafluorophosphate localization; in addition to lithium hexafluorophosphate breakthrough in the field, the equity investment projects put into operation, aluminum with a fluoride salt in the dominance of the field will be further strengthened. We expect 2010-2012, Fluoride earnings per share were 1.01,1.51 and 2.03 yuan (which lithium hexafluorophosphate contribution to 0.00,0.16 and 0.61, respectively dollars).

The broker also recommended attention to when the rise of investment opportunities. Report, as the largest, the world's third manufacturer of lithium cathode materials, the company with product quality as Samsung SD I, LG Chemical and other major international supplier of lithium batteries. In 2009, when the rise of science and technology to obtain quality BYD and Sanyo Energy approval, the company expects its sales will increase rapidly. 2010-2012 the company expects earnings per share were 0.78,1.33 and 1.76 yuan.

From a technical point of view, included in the "energy-saving and new energy vehicle demonstration and application of recommended models directory" of the 100 models, with lithium battery-powered about 60, including lithium iron phosphate and lithium manganese oxide proportion about 7:3. The future of lithium battery market will be officially launched on the lithium battery manufacturing industry chain development of enterprise opportunities, focus on a more complete industrial chain with companies such as CITIC Guoan, China Baoan, Shanshangufen, and areas of expertise with technology advantage of the company, such as new chou, Jiangsu Guotai Fosugufen.

Infrastructure-related investment opportunities in stocks has also been seen. Changjiang Securities released a report that this also released a "private purchase of new energy vehicles pilot Interim financial subsidies," said local governments to certain funds, focusing on the charging stations and other infrastructure to support it. At present, subsidies for new energy vehicles in the battery can basically cover the price increase brought about, the biggest bottleneck restricting the universal charging station that is / columns and other infrastructure deficiencies.

Report, "General requirements for electric vehicle charging stations" and for Approval has been submitted to the National Standardization Management Committee, expected to be granted during the year, so the future with the construction of a large number of charging stations around the start, has entered the field equipment suppliers will become the new energy automotive industry chain of the first groups to benefit include: Hidenobu shares, XJ Electric, National Power South, NARI, Auto Motion, Siyuan Electric, Senyuan Electric.

Timing of investment vehicle yet

"We believe that the new energy passenger car industry chain (the current policy emphasis on promoting plug-in hybrid electric passenger cars and passenger cars) overall, 3-5 years, will continue to research and development, road test, the accumulation of the stage of empirical data, and "auto industry and restructuring plan" put forward new energy vehicles in 2012 to reach 5% market share a lot of pressure to achieve the objective (expected to more than 900,000.) electric car industry also need to address several key problem: battery life, infrastructure, automotive battery's durability, which takes time. "from Guoxin Securities, said such reports.

The report said this context, the relevant company's share price driven by "the race and earnings expectations," 3-5 years, mainly by the expected promotion. In the electric vehicle penetration rate of 3-5% before, will remain an ongoing process of large-scale investment and the burn is difficult to realize large profits, then, the market structure will be stabilized, some companies were eliminated, high-quality corporate profit . Long-term investment products to choose from is not easy, as the division of corporate earnings, stock prices will be significantly differentiated.

Minsheng Securities also believes that the notification of new energy vehicles models to benefit less, short sales difficult to break.

The release of the report, the pilot cities to buy plug-in hybrid and pure electric vehicles subsidies, require the applicant to supplement the auto companies and the new energy automotive products must be included in "energy saving and new energy vehicle demonstration and application of recommended models directory" , the current directory of new energy vehicles, 27 passenger cars recommended species, only 12 kinds of models can get subsidies for new energy vehicles. These models are selling now are limited, and some models not yet listed. Subject to technical and infrastructure bottlenecks, particularly in supporting maintenance and charging facilities, subsidized sales of short-term model there is no breakthrough. Therefore, "subsidies for new energy vehicles will help the pilot started the city's new energy auto sales, but short-term subsidies for new energy sources have limited impact on car sales, little effect on the performance of the company."

State Securities, said the new energy automobile companies, including Shanghai Automotive, Chang'an Automobile, Foton Motor, etc., drop by the main business cycle effects in the short term can not be optimistic, optimistic about the long-term worth. Recommended to avoid no substantial results support the concept of blind speculation of new energy vehicles.

But Merchants Securities (HK) that, though the BYD car prices as well as other new energy point of mass production and profitability still need to be patient, but due to the intensity of the basic allowance in line with earlier expectations, so prices will directly benefit from the relevant vehicle .

"For example, we covered the company in shares of BYD (01211. HK), the company's pure electric vehicle E 6 and F 3D M dual-mode electric vehicle will directly benefit from government subsidies. With the company to determine, E 6 present price of about $ 300,000, according to government subsidy standard, E 6 will enjoy up to 60,000 yuan subsidy, then the price will be to 24 million; F 3D M current price of 169,800 yuan, will enjoy the highest subsidies 5 million, the price will drop to 11-12 million, appeal greatly increased. "

New energy auto industry research: hybrid into the mainstream

China will develop new energy vehicles, because the issue of energy security and environmental protection to promote China's need to develop new energy vehicles; new energy vehicles in China's automobile industry an opportunity to catch up by leaps and bounds, China's domestic automobile manufacturers have mastered a certain related technical strength

Cars going to be a conventional internal combustion engines, alternative fuel internal combustion engine, hybrid, electric vehicles and fuel cells coexist

Liu Hanyuan to book to answer the four questions photovoltaic industry

2011-08-12T01:59:00.001-07:00

Liu Hanyuan to book to answer the four questions photovoltaic industry

"Excess that" debatable

"Energy Revolution: Change the 21st Century" before publication, for "whether the excess polysilicon industry," said Liu Hanyuan, "Five years ago, China's production of polycrystalline silicon solar cells by more than 99% of imports in 2009, 50% of our own supply of polysilicon, This is a very fast and last year we said excess, and no one thought to rely on last year imported 50% or so 'surplus that' questionable this year, we have 1 / 3 of the polysilicon to rely on imports, that the year after that its good to meet you in such a premise, in the event of financial crisis, I think the intention of government regulation is mainly to remind the possibility of excess, to remind you to pay attention to investment in rhythm. is not only the PV industry, any industry need to pay attention to this problem. "

For polysilicon production of high-energy challenge, Liu Hanyuan said, "If the proper process control center itself does not consume energy, the energy is consumed to maintain the production process as part of the production process consumes energy. Why do we say it is high energy? Because manufacturing process, the polysilicon per kilogram to about 100-200 kWh consumption, high crude look, but we are now doing the result is put into an electricity production of polysilicon, and finally the formation of solar PV modules, which effective life cycle can return 15-20 kWh, up to 20-30 kWh, this unique in the history of human energy consumption. "

Environmental governance is almost zero emissions

For questioned the high pollution industry, Liu Hanyuan said, "This is the concept of the formation of the past and many years ago, people did not master the technology, basically there is no way for recycling, emissions of hydrogen chloride, silicon tetrachloride, and sometimes simply a rushed it, resulting in the pollution emissions, while the new production process, including the mainstream formal manufacturers, it is impossible to see the sky leak, the contamination of the floor, which is a modern business concepts, environmental management is almost done to zero emissions. "

Some people ask, the rise of the domestic film solar cells, polysilicon industry will bring great impact on? Liu Hanyuan confidently said, "We also note that new technologies such as thin-film solar cell research and development and use, but as long as we are a little analysis, from the 1950s satellite into space, to today's International Space Station construction and use for decades, without exception are silicon photovoltaic cells. crystalline silicon solar cell battery as an international mainstream market, especially in the world based on decades of semiconductor silicon materials and technology more sophisticated and mature, it accounted for more than 80% market share, especially grid-connected photovoltaic power generation projects, almost all the good stability, high conversion efficiency of crystalline silicon cells. combined with thin film technology in the technical, environmental impact, especially by the low conversion efficiency of the bottleneck factors, difficult to replace thin-film technology polysilicon in the foreseeable future, the PV industry, polysilicon is still the mainstream and core materials. "

"Obama's Magic" is the core energy revolution

Since 2009, "low-carbon economy" is one of the highest click rate terms. Low-carbon economy is the most important part is to find permanent sustainable development of new energy. According to the International Energy Agency predicts that oil can also be used about 40 years, natural gas can also be used about 50 years, coal can also be used about 120 years. Energy security and food safety has been a threat to human survival.

New energy to become the 21st century "savior" it? Before U.S. President Barack Obama's words in his inaugural speech, "the way we use energy ... ... threatens our planet." Straightforward point to understand the extreme importance of the new energy revolution. Data show that U.S. fiscal year 2009-2010 spending of 3.6 trillion dollars, the deficit reached an unprecedented $ 1.75 trillion. Obama announced the 2013 deficit should be reduced to $ 53.3 million, about 4 years time is to use large-scale reduction in the deficit out of $ 1.217 trillion. By the world known as "Obama's Magic" is the core of 'Energy Deal', the Americans hope that the world economy to achieve wheel drive: use the dollar bill in relying on the wheel, we must also rely on "the amount of energy," the new wheels.

China needs the U.S. to follow up the start button

Currently, the community insight that humanity is facing, "the fourth industrial revolution", and the Industrial Revolution's mission is to create a large number of new and renewable energy. The past, carbon combustion-based industrial model has come to a turning point, must be changed. U.S. energy revolution has started the button, which calls for China but also to keep up with rapidly, in order to accelerate the new energy revolution.

In fact, the Chinese government is actively taking appropriate measures. Vice Premier Li Keqiang has stressed that: "The new energy industry is pregnant with a new economic growth point, is a new round of international competition, the strategic high ground, the current international financial crisis, the energy industry for new opportunities, we should develop new energy sources as important measure to deal with the crisis. to strengthen policy guidance to support and promote wind, solar, biomass development, and promote new energy vehicles, energy efficient buildings and products, widely used to speed up with new energy and energy saving technology to transform traditional industries, as well as promoting energy the adjustment of industrial structure. "

Revitalization of China's new energy industry planning, the Government has the energy to the national strategic level, put into force the boot drive. The future of China, the new energy revolution, the first requirement is that the "new energy" to import, such as wind, hydro, solar, nuclear power and so on. In the new energy plan, the government made a major new energy arrangements will be put up to 3 trillion yuan to promote the development of new energy sources.

Electric vehicle batteries and six major issues facing the industry exams

Electric vehicles to be more widely promote the use of its main difficulty is that high-performance power source technology has not been effectively resolved, existing products can not meet the car on battery life, power and other performance requirements.

Currently, the battery products generally face the following problems:

Battery safety can not be guaranteed. Currently small and medium-capacity lithium-ion battery industry has been very successful, but high-capacity, high-power lithium-ion battery safety problems are not effectively addressed. The battery capacity is greater, the harm caused by out of control once it gets.

Battery capacity is limited, failure to achieve a breakthrough. Currently on the market use of electric vehicles on a single charge of driving range is usually 100km ~ 300km, and it also needs to maintain proper speed and has good battery conditioning system can be guaranteed, but the vast majority of electric vehicle under normal driving environment driving range is only 50km ~ 100km.

Battery cycle life is short. Ordinary battery charge and discharge times of only 300 to 400, even if the good performance of the battery charge and discharge times, but also 700 to 900 times, 200 times per year calculated discharge, a battery life of up to 4 years, compared with the life of automobile fuel than too short.

Battery quality and size constraints. Outside the existing size of battery electric vehicles generally achieve 550L. When such a large volume of batteries used on the family car, the car is bound to squeeze the luggage compartment. Existing battery electric vehicles are not used enough energy in storage to maintain the premise of reasonable size and quality.

Batteries are expensive. Electric car batteries cost about $ 100 / kwh, and some even as high as $ 350 / kwh, the cost is too high, users unbearable.

Environmental pollution. Battery currently used primarily for lead-acid battery, nickel metal hydride batteries, nickel cadmium batteries. Raw materials from mining to production, to waste after processing, will pollute the environment.

In addition to these six problems, the electric car battery industry is also facing exams. In China, Xianyang power grams of energy Co., Ltd., Guangzhou Great Power Battery Co., Ltd., Tianjin Lishen Battery Co., Ltd., Dongguan ATL (new energy) Electronic Technology Co., Ltd., Taiwan's Aerospace Industrial Development Corporation has successfully developed a number so small lithium-ion battery, but high-capacity, high-power lithium iron phosphate battery technology development has not been successful.

Overall, good prospects for the development of battery, but the market is still low, take time away from the real industry. Moreover, the battery business to really bigger and stronger, but also to withstand the industrial scale, large-scale R & D investment and foreign giants squeeze test.

Qingling Group and the Harbin Institute of Technology research and development of lithium iron phosphate production in Qingdao

PV, thin-film crystalline silicon who play a leading role

2011-08-07T23:57:00.000-07:00

PV, thin-film crystalline silicon who play a leading role

Crystalline silicon solar power plant in the maturing of the situation, the thin-film solar cells also began to compete in this potentially huge market. The two technologies compete in the behind, is Applied Materials, Inc., international solar companies, solar energy equipment manufacturers compete between.

May 26, using the Applied Materials equipment, ENN Solar Energy Co., winning solar power plant in Inner Mongolia, is used in thin-film batteries. Prior to Dunhuang, Wuxi and other domestic solar power stations all use crystalline silicon solar cells to generate electricity.

"This is China's largest amorphous silicon thin film battery power generation projects." NDRC Energy Research Institute, Li Junfeng, deputy director told the "First Financial Daily." This is the first thin-film battery domestic power projects.

Advantages of thin-film battery Losing?

New Austrian photovoltaic successful projects, energy saving by the China Investment Corporation, the first phase of the project is 10MW, respectively, and 5MW 5MW thin film crystalline silicon cells.

Applied Materials Asia Pacific Channel Director Xiao Jinsong told the newspaper, compared to crystalline silicon cells, thin-film battery is more suitable for solar power applications.

"But I do not deny the advantages of crystalline silicon cells, in fact, have their own advantages and disadvantages of the two cells." Xiao Jinsong, said crystalline silicon cell power generation more efficient, but cost is also high; Although thin-film solar cell power generation efficiency is lower , but the cost is relatively low.

LDK Solar's president agreed to do director Yao Feng Xiao Jinsong point of view. "Some people these two technologies as a competitive technology, in fact not the case." Yao Feng told the newspaper, thin-film battery applications with low light intensity and temperature adaptability of the characteristics of large-scale power plant used in the desert , and a larger temperature difference between land rich in natural resources or areas of power plant construction, in addition to the main glass curtain wall is also thin-film battery; and city roof projects, require high power generation efficiency, it is mainly the use of crystalline silicon cells.

But Xiangcai Securities analyst Houwen Tao believe that with the decline in the price of polysilicon thin-film solar cells in cost and crystalline silicon cells is not much advantage.

Before the financial crisis, polysilicon prices continue to surge, the high cost of polysilicon in response to pressure, LDK and other domestic companies launched a number of thin-film solar cell projects.

2007 global thin film solar cell production reached 400MW, 181MW in 2006 a substantial increase of 120%; 2008, the global thin-film solar cell production reached 892MW, an increase of 123%.

After years of rapid development, thin-film solar cell market began to cool. The first quarter of this year, Oerlikon sales fell to 39 million Swiss francs (about $ 33,988,500), down 24%; in the first quarter order intake is only 800 million Swiss francs (about $ 6,972,000), down 27 %.

Equipment giants compete for Chinese market

Although LDK Solar LDK, Suntech and other domestic companies, as the current round of explosive growth in solar power the biggest beneficiary, but from the perspective of the global industrial chain, Oerlikon, Applied Materials, Inc., United States GTSolar other solar equipment manufacturer is earn more profits.

Applied Materials company told the newspaper, a thin-film battery production equipment needs hundreds of millions of yuan.

Now, the focus of these companies are gradually moved to the Chinese market.

In 2006, Applied Materials, Inc. before entering the photovoltaic market. In order to develop the Chinese market, the company's executive vice president, chief technology officer, Ke-Ping Ma (Mark R. Pinto, Ph.D.) began in January this year, the Permanent Mission of China.

Currently, the company and two Oerlikon to become the world's largest manufacturer of thin-film battery devices.

Applied Materials, Inc. engaged in both crystalline silicon cell manufacturing equipment, but also engaged in manufacturing thin-film battery devices. Ke-Ping Ma told the newspaper: "We are in the crystalline silicon manufacturing equipment, 75% of orders are from China."

In order to better seize the market, Applied Materials, Inc. in Xi'an deliberately set up a research and development center.

Earlier this month, the Shanghai PV conference, Tom Gutierrez, president of the United States GTSolar also told the newspaper, the company accounted for polycrystalline silicon devices (ingot furnace) is 70% domestic share.

In the first quarter of serious decline in the Oerlikon same. Oerlikon CEO Jurg Henz in an interview with reporters that: "China is our first important market, although we are now in Germany, there are some customers in southern Europe, but we are very optimistic about the Chinese market."

Currently, Oerlikon has 12 customers worldwide in the production, of which there are two in mainland China and Taiwan, two, three in Germany, southern Europe has three.

Photovoltaic industry to find the fog line before the breakthrough in the industry

Photovoltaic industry to find the fog line before the breakthrough in the industry

Solar power, may be the first to enter the Chinese people at home in the new energy technology. However, in 2009 a surplus of polysilicon photovoltaic industry debate also made a new field of energy development in the first cast a shadow of the industry.

Feed-in tariff dystocia

A case of sharing

The development of photovoltaic industry in Qinghai, the enthusiasm of enterprises is high, do not worry about the emergence of social investment in place, the need for government to support subsidies. However, delays in the introduction of photovoltaic electricity, so that many enterprises only waiting in the wings, do not want to rush shots to start building. As the country's provinces and lowest cost solar power, photovoltaic power generation cost of Qinghai in about 1 yuan, which is the current cost of conventional energy generation have a 0.5-0.6 million gap, the gap is the part of government subsidies needed shot. For PV "Tariff Act" will be announced, but no clear state, which makes many new energy companies rather anxious. CPPCC National Committee member, Tong Wei Group Chairman Liu Hanyuan, says that the core of the current development of photovoltaic industry, the bottleneck is to solve the problem of electricity price, electricity price one day no domestic polysilicon enterprises rely on only one day export capacity surplus, industry profits can only be bound to low.

Some people think that the core issue is how much countries are willing to subsidize the development of solar, photovoltaic industry in the EU policy in the fog.

Where a breakthrough?

Solar PV industry is a large market size, industry wide area, driving significant effect of a sunrise industry. Experts have suggested that want to closely follow China's PV industry to a new round of world economic development, strengthen industry R & D, to seize the emerging industries of strategic national development time.

Accelerate the localization of photovoltaic energy equipment

Solve the problem because the cost of photovoltaic power generation is the key to achieving the upstream and downstream production battery system integration costs, of which the upstream part of the cost of production is the most important factor. More feasible way is through the promotion of photovoltaic cells to boost domestic production equipment, battery manufacturing process optimization to improve product yields and conversion efficiency, reduce raw material consumption, thus achieving a significant reduction in the cost of batteries, solar power and to achieve the traditional balanced energy generation costs, and ultimately promote wider application of solar energy. PV cell production equipment in China, it is necessary to establish research base, take the combination of technology development and industrialization of the road can be achieved.

Increase the intensity of the smart grid construction

Construction of smart grid to the PV industry to bring great good. But the current lack of a national smart grid also clear strategic positioning - the development of what, how to develop and who need to further clarify development issues.

It was suggested to upgrade to smart grid power system intelligent building height, and their integration into the national energy strategy planning, "second Five Year Plan" and the major national science and technology projects.

Launched the "Tariff Act"

To accelerate the development of photovoltaic industry, the most important is to solve the electricity price. Grid is motivated to buy, end-user's willingness to use is the most critical. Therefore, to develop photovoltaic industry. Development and implementation of photovoltaic power generation "Tariff Act", is particularly urgent.

Not seeking the latest and most unusual but to "affordable"

2011-08-02T19:26:00.000-07:00

Not seeking the latest and most unusual but to "affordable"

All begins with the Expo.

It is said that each session of the Expo are some of the protagonist, as a landmark innovation has changed human life. For example, in 1851 the first steam Expo to promote the textile machine, 1878, the lights of Paris Expo, 1893 Expo in Chicago telephone. Indeed, in an endless stream of new inventions of industrial civilization, they are spread as the protagonist of the Expo the world.

If, however, entertain the hope that by 2010 Shanghai World Expo the core theme - Urban Best Practices Area to find, may be disappointed. Here of course there are robots, there are LED lights, there are solar panels, etc., but can not be called particularly "new."

In fact, this is the place the times Expo. Information developed, frequent exchanges of the 21st century, show the latest and most sophisticated technology the stage after another, does not make the Expo specifically the United States. Modern achievements of mankind from the show turned to concern for the environment and sustainable development, shift from simple product display showcase culture and ideas, to people from focusing on a novel inspired to focus on people's lives and ways of thinking, the Expo has opened a new chapter in the history of .

Expo will be "Better City, Better Life" as its theme, the show "art" but also more important to convey the concept of technology: how technology and the process of human civilization and social life more harmonious integration? Sometimes, the technology good enough.

Clever thoughts achievement, "best"

Throughout the region many cases E tablets that were a "clever mind" will gently hit your heart.

Let us look at water from France Alsace curtain Sun City -

Impression is caused by a modern glass curtain wall building "warming" of the culprit, but here it is the key to achieving cool. Glass curtain wall from outside to inside, including three levels, the outer layer may be opening and closing of windows, covered with solar panels, the middle air layer, and finally a layer of water curtain glass. Winter, all the windows all closed, the middle laminated air, in the sun and photovoltaic panels generate electricity under the action of heat, the temperature will rise rapidly, these warm air into the building, can reduce air-conditioning system, heat consumption. In the summer, the outer layer of glass open air; water curtain constantly scouring the inner glass, the middle layer of the air temperature is naturally lower, the same token, can cool the entire building up. At this point, the energy generated by solar panels power source is water curtain, panels themselves can play a shading effect.

Solar photovoltaic power generation, international is a mature technology, cost of power generation is increasingly approaching the traditional coal; pumps, is commonplace; The windows open for ventilation, but there is no technical content of the "knowledge of life." However, through their ingenious combination, can effectively reduce the use of conventional air-conditioning, called "low-carbon model."

Similar examples abound in the best practice area. House in Hamburg, Germany, France Law - Alpes Case Hall, invariably using plastic frames, improving insulation, on the technical content, it is not really high-end plastic frames; Taipei Case Hall introduced the "Zero Landfill" experience in waste separation, incineration, and other aspects of extraction of useful substances, there is not much remarkable new technology, on the contrary, is a careful and detailed management methods to create Taipei's success ...

"The appropriate technology" with great wisdom

Best Practice Area "not seeking the latest, but for the most appropriate", has been widely recognized by Chinese experts. Zheng Ling Chinese Academy of Sciences said, "This show is not necessarily the Expo is a huge novelty device, it could be very useful but obscure technology," The secret to hard to understand.

From the industrial revolution, people are constantly chasing new technologies and new achievements, has made great achievements, and thus profoundly changed the panorama of life. But the pursuit of the application of new technologies also have a scale, extremes meet the law applies. Such as pesticides, came at the beginning is seen as the most dazzling new technology, but since 1962, Rachel Carson in "Silent Spring" in issue "in the wilderness is heard shouting," people realized that "great" pesticides is not as good as imagined. Even today, people want to re-bid farewell to pesticides, is how difficult.

Shanghai Jiaotong University history of science and philosophy of science department head Professor Jiang Xiaoyuan that people's understanding of technology, has long been deep misunderstanding. Especially in China, many people who blindly support the new technology, fearing their own date. Climb cutting-edge science and technology high ground, of course, strongly encouraged, but the objective point of view, the most cutting-edge technology may not have the best application results.

In addition to developing its own technology agnostic, application and popularization of difficult, has become the most cutting-edge technology, "Achilles' heel." Take the example of fuel cell vehicles, as opposed to eagerly look forward to the eyes, it's the pace of industrialization, still seems a bit slow. Of course, application and popularization of fuel cell vehicles must not give up, but a wise city planners, when he wants to build a low carbon city, the city is to choose to use fuel cell vehicles, or combination of hybrid and pure electric vehicles, and then supplemented by a small amount in a specific area of fuel cell vehicles? In the present case, a choice which actually much more effective? The answer is self-evident.

From this perspective, the best practice area shows how good "affordable" technology, called the "great wisdom."

Blind novelty, low-carbon road narrows

Spanish Pavilion with rattan shade; Singapore Pavilion to enhance natural ventilation, reduce air conditioning use ... ... from the Urban Best Practices Area to the Expo site, select "by the appropriate technology" to reduce dependence on complex technologies become a very common phenomenon . Unfortunately, on the people who, "by the appropriate technology" still arrived, but sometimes "cool new" bright light.

Wind resources are not abundant in some areas, in order to show the local new energy technology advanced, rushing to build "new largest" wind farm, hesitate to spend huge construction costs. In fact, the running time of each wind farm is not only limited follow-up grid and other complex issues remain unresolved, and it is almost impossible to really have a "green power." In fact, it is low-carbon technologies, many experts agree that the vast majority of environmental problems to solve today's technology, has basically mastered by humans. Even in traditional coal fields, there are also many technical solutions can achieve emission reduction, but the problem is that these people are not willing to mature technologies and large-scale promotion of rational use, but the blind pursuit of the latest cool, potentially low carbon The road becomes narrow.

Fortunately, Shanghai, this "wisdom" does not lag behind. Back in 2007, the Municipal Science and Technology in the Minhang district of a new residential buildings to promote energy-saving attempt, involving dozens of technology can not be called "the latest and most high-end", but together, energy-saving effect is obvious. Relevant responsible person said, even more play in the future similar to the "combined", the groups of mature technology to launch to achieve maximum application.

In addition to low-carbon hot nowadays, new energy, there are many other areas because of "performance concept," "prestige projects" and other utilitarian considerations, the blind pursuit of "high tech" phenomenon. Some companies, the introduction of the device must be the "most advanced" technology; the contrary, has many years of safe operation of old equipment, old technology, can meet the production needs of the case has been eliminated. Study of its psychological, as if with the latest and most sophisticated technology in order to demonstrate its superiority and a sense of accomplishment. By Professor Jiang Xiaoyuan point of view, technology was originally an important means to achieve sustainable development, and too much reliance on "cool new" technology, in order to achieve "sustainable development", which itself has become "unsustainable" the.

Polysilicon industry access standards were finalized pending

May 17, the Ministry of Wang Bo, deputy director of electronic information in the Photovoltaic Industry Association, told reporters during the inaugural meeting, "polysilicon industry guidance" and "polysilicon access" has been developed is completed, is being submitted to higher authorities for approval , announced shortly.

September 2009, the State Council issued "on the curb overcapacity in some industries and duplication, and guide the healthy development of industry, a number of opinions" (ie, the State Council No. 38), raised the problem of excess production capacity of polysilicon.

Since then, the Ministry of Industry and Information Technology Vice Minister Chen said demand made under section 38 of the text, to 2011, out of overall power consumption over 200 kWh / kg of polysilicon production capacity.

According to the Ministry's requirements, the new polysilicon project size must be greater than 3000 tons / year, covers an area of less than 6 ha / tons of polysilicon, solar grade polysilicon to restore power consumption of less than 60 kWh / kg, reducing exhaust tetrachloro of silicon, hydrogen chloride, hydrogen recovery efficiency of not less than 98.5%, 99%, 99%.

Wang Bo pointed out that the domestic PV industry still has many problems. One is the tendency of overheated investment polysilicon industry.

Survey, the domestic polysilicon industry plans a total investment of 134 billion yuan, the actual investment of 47 billion yuan; has completed project design capacity of 40,000 tons of production capacity in the construction of the project design more than 60,000 tons, a total of approximately 10 million tons (at present level of investment in the industry about 800 million per one thousand tons to 10 million).

Although the capacity building project design includes step by step implementation of the proposed multi-phase construction of the target, but if not timely to regulate and guide, continued capital investment, a large number of projects focused on construction, there will be overcapacity. Wang Bo said.

On the other hand, the key domestic polysilicon production technology, product quality and cost with the international advanced level is still a certain gap between the crystalline silicon solar cell production line still has to import high-end equipment. Thin-film solar cell production equipment and abroad there is a large gap; part of the supporting materials for solar cells, not get rid of dependence on imports.

In addition, the domestic photovoltaic industry also lacks a standard system. Wang Bo said polysilicon production is not uniform energy consumption, area and environmental standards, technical standards for photovoltaic products and applications development behind the market development, product quality certification system is not perfect.

Wang Bo said the two upcoming document is in line with the implementation of the State Council No. 38. In order to prepare two documents, the Ministry has been for several months, multiple thoroughly research.

Day, in the Ministry of Electronic Information Division and the Division of Development and Reform Commission under the guidance of high-tech domestic 23 units (20 for photovoltaic enterprises) to establish China Photovoltaic Industry Association, Wang Bo unit League Secretary General.

Ministry of Industry and Electronic Information Division Xiao Hua, said the industry alliance formed to deal with international competition in the industry is an effective way for the development of China PV industry milestone, marking the Chinese PV industry work together into a joint development new era, the Union will work to integrate industry resources to promote structural adjustment, change the mode of development, and enhance industry cohesion, to expand its international influence.

An industry source said the photovoltaic industry, Union will rely on the Ministry of Electronic Information Division, may participate in the relevant standards under development.

2011-07-25T02:04:00.000-07:00

"Sunshine quality services worldwide," President Chen Kangping in JinkoSolar business cards, printed with these eight words.

Chen Kangping back from the States, even more busy: phone instructions, listening to the reports, which also lack Zhu Hejing Branch successfully listed on the New York Telephone.

Must attack in Chen Kangping about the grain market of the extraordinary history of the New York Section ... ...

The first international financial crisis, the U.S. domestic market

PV industry in China is an emerging industry, but one unique pace of development. To the international capital market to logistics, but also the way the operation of the PV business. December 14, 2005, Suntech directly visit the New York Stock Exchange, becoming China's first listed on the NYSE's private high-tech enterprises; June 1, 2007, Xinyu LDK in the New York Stock Exchange. 2008 before the outbreak of the international financial crisis, just two years, China has nine PV companies in the New York market, China's solar industry appears to be rising.

The rapid rise in the red earth of Shangrao JinkoSolar in July 9, 2008 officially launched the "to New York market," the action. However, a global disaster is slowly coming: from the U.S. "subprime crisis" caused the financial crisis in August 2007 throughout the United States, European Union and Japan, the world's major financial markets; September 2008 the international financial crisis broke out. Face of international financial order, chaos, had to temporarily put aside JinkoSolar listing.

Opportunities always favor those who are prepared. JinkoSolar positive development and growth in business at the same time, efforts to capture opportunities. In the "haze" began to play down the first time in February this year, JinkoSolar a road show arrived in New York, but because the reason for the low issue price, JinkoSolar give up. Recently, JinkoSolar trip to New York, decent performance, greatly welcomed by the New York capital markets. May 13, JinkoSolar pricing in the New York Stock Exchange, May 14, officially listed as the tenth Chinese PV companies in the United States home, second home in Jiangxi Province, the international financial crisis, the first company in the United States PV Enterprise is the first city in the international capital markets businesses. The market issued a total of 583.5 million American depositary receipts (ADS, each ADS representing four ordinary shares) at an issue price of $ 11 a share, raising total of $ 64,180,000.

"We just Jingke a listing in New York City, Zhejiang, Jiangsu, Chongqing and a number of PV companies are applying for the U.S. market." The successful listing, Chen Kangping that the main reason is the performance of crystal families, Despite the severe financial crisis in the international situation, JinkoSolar every year to achieve solid growth, good profitability.

The United States is the center of global capital markets, coupled with the crystal families, mainly in Europe and America market, which is found in the United States of Chen Kangping reason. He said that in the United States, marking the crystal families to move toward the international capital markets, not only in the capital to provide a guarantee, more conducive to enhance the company's brand image will help build an international sales network, will help to enhance the level of scientific research.

Forward to a world-class PV companies

Branch Energy Ltd Crystal Technology Co., Ltd. from Hong Kong to invest in Parkes, December 23, 2006 settled in Shangrao Economic Development Zone with registered capital of $ 190 million, they "create a bunch of sunshine each value" for the purpose, commitment to single-crystal silicon rods (films), polycrystalline silicon ingot (film) and solar cell module product development, production and sales.

The efficient cause of the rapid development trend of attention from people outside the industry:

In 2007, the wafer production capacity 80 MW, the sales income of 780 million tax 38.6 million yuan.

In 2008, the international financial crisis, prices fell 70 per cent of the face of adversity, wafer production capacity expanded to 220 MW, the sales income of 3.0 billion, tax 120 million yuan.

In 2009, solar wafer and cell components of capacity 300 MW, respectively, sales of 2.06 billion yuan, total profit and tax over $ 300 million.

Solar energy is the human inexhaustible energy. Determined to follow the sun light crystal families, has an ambitious goal: By 2010, the company's silicon, cell component production capacity of up to 500 MW; 2011, wafers, cells, cell components, respectively, production capacity 1000 MW in three years to fight the crystal families of the world's best single silicon chip and battery components of the brand, the world's leading photovoltaic companies.

JinkoSolar listed in New York ticker JKS, JinkoSolar English jinkosolar for the shorthand. solar, in Chinese means: the use of sunlight. The sun is new every day, we believe, will be able to catch up Jingke pace of the sun, making big strides!

The formation of ultra-thin flexible printing all-solid lithium-polymer rechargeable battery

Mie Prefecture Industrial Support Center is developing ultra-thin flexible sheet, characterized by lithium polymer rechargeable battery. The battery for the use of all-solid-type solid electrolyte, the possibility of fire and explosion greatly reduced. It may also be technology-based printing roll to roll process for manufacturing, is one big feature. "Nikkei Electronics" has been on the whole sheet of solid lithium polymer rechargeable battery trial production line for the interview opportunity.

Trial production line can be divided into two parts, a new generation of battery development is the Mie University of the facilities of the other part is the Mie Prefecture Industrial Support Center for Advanced Materials innovation center facilities.

Accelerate the restructuring of China's automobile industry

2011-07-19T01:03:00.000-07:00

Accelerate the restructuring of China's automobile industry

Recently, China has the greatest influence of the 10 key auto groups (SAIC, FAW, Dongfeng, Guangzhou Automobile, Beijing Automotive, Chang, heavy truck, Brilliance, Chery and JAC, hereafter T10 enterprises), co-sponsored the traditional car coordination of energy-saving and new energy vehicle development strategy and new energy vehicles common framework for action aimed at China's efforts to promote and accelerate the development of new energy automotive industry, promoting China's automobile industry from large to strong forward.

New energy development is imperative

T10 enterprise made the world's automotive industry (including the Chinese automotive industry) is facing three major challenges for sustainable development: energy supply and energy security, regional air quality and global warming. Vehicle energy and energy saving power system is the core issue of sustainable development, the automotive industry and the most important issue, energy diversification, energy-saving and lightweight vehicles, emissions of clean, electric power development trend of the automotive industry. To this point, is to develop energy efficient cars and the electric vehicle as the main body of the new energy vehicles.

China Automobile Industry Association Executive Vice President and Secretary General Dong Yang in an interview with reporters, said that China's automobile industry is currently facing industrial restructuring and sustainable development pressures, there are industrial security and economic security issues, the situation is very serious. On the one hand, oil security has become the first development of China's automobile industry constraints. In 2009 China's dependence on foreign oil close to 52 percent, is expected to further increase the future. On the other hand, China's automotive industry is facing severe energy saving, emission reduction and carbon reduction pressures, the traditional automotive technology level and international advanced level there is a wide gap between fuel consumption and carbon emissions will become the main obstacle to the world car. Therefore, the development of energy-saving and new energy vehicles, China's automotive industry not only become the inevitable choice for sustainable development, but also the social responsibility of China's automobile were reflected.

Dong Yang said the auto industry has recognized that traditional energy-saving and new energy vehicles, automotive development is related to the economic development, sustainable development and the automotive industry on major issues of people's lives. He hoped that the attention of the community, making the energy to achieve rapid results, to support the sustainable development of the automotive industry, making the new car as a strategic new energy industry has a very good development for the sustainable development of China's economy has played an active role.

Still a gap between high-end technology

It is understood that, after years of efforts, China has initially established a hybrid, pure electric and fuel cell "three vertical", the battery, motor, electric control "three horizontal" layout of the development and technical system; initially acquire new energy automobile development technology , battery and motor made important progress in some of the products to meet the demonstration of basic operational requirements; some of the products to achieve a small batch production and demonstration operations, the industry is gradually advancing. Meanwhile, the initial formation of energy-saving and new energy vehicle technology standards and test evaluation.

Experts believe that the achievements of these years, although significant, but there are still many problems to be solved. R & D investment in new energy vehicles in China long enough, there is a certain gap between high-end technology; products, lack of adequate test verification and improvement in high-end technology and industrialization with the international advanced level there is a big gap; key parts of the industry chain has not yet formed Most of the key raw materials, dependence on imported components and manufacturing equipment, infrastructure planning and investment is not clear; standards of integrity and availability needs to be improved, industrial capacity needs to be improved; and new energy vehicle development on traditional automotive technology, such as vehicle electronic control, lightweight, electric air conditioning, power brakes, power steering, transmission and other electro-mechanical coupling, there is a big gap.

To this end, new energy vehicles as a new strategic industry, and needs the joint efforts of the industry, the need for industry collaboration on research, need to give power of the country together to promote development.

Energy needed to power "standard"

An Zhao practice at home and abroad, a country can not be regarded as automotive power is necessary to comply with several standards, in automobile production and sales, China has Meiyou problem, in addition, the share occupied by its own brand and quality technology improved a lot . But in addition to the above standards, experts, the future vehicle power must have its own core technology, the system has power lines that can integrate into the global automotive network, has a major global automotive manufacturers and suppliers, and leading the development of the global automotive responsibilities and capabilities. Relative to the U.S., Japan, Germany and other markets, China is the lack of technology and products such as General Motors, Ford, Volkswagen, BMW, the world's top global manufacturers and suppliers. China still exist in the automotive quality, service, domestic technology development, environmental protection and other deficiencies.

For the current status quo, T10 companies jointly proposed the development of new energy vehicles in China's strategic objectives: T10 companies will together all sectors, with two five-year planning time, in 2020, including efforts to enhance vehicles and new energy vehicles, including traditional energy automotive technology reached the international advanced level, some technology is a world leader, China has become a real car power.

Efforts to promote the transformation of automotive energy power systems. By 2015, the pure electric vehicle up to 50 million or more; electric technology is widely used in conventional vehicles, hybrid vehicles of different levels of the proportion of annual output of more than 30%; new energy vehicle and key parts of the industry to achieve the world advanced level; average cycle fuel consumption of new cars dropped by 30%, and reached the international advanced level.

Qi together cutting-edge power control

China's automobile production and sales has been a power, but has to become a "new cutting-edge automotive technologies," the real power, experts say, it needs at least about five to six years. This also needs China's major automotive manufacturers to expand and develop the global market, and this process may be in the next 10 years.

To this end, T10 companies jointly developed the action of specific objectives, namely: T10 line business to the world-class companies, R & D costs account for more than 3% of sales, in all areas, including electric vehicles, hybrid vehicles, fuel cell vehicles and alternative fuels automotive technology, automotive fuel-efficient technologies and traditional technologies, including new research, by 2020 the formation of world-class research and development capabilities; to pure electric vehicles into the product planning, strategy, and gradually increase the R & D investment, to further understand the vehicle and key system core technology. At the same time, actively cooperate with the government to carry out the work of the new energy vehicle demonstration runs from the development of pure electric passenger vehicles and large passenger cars start small, gradual industrialization; efforts to promote hybrid vehicles industry, focusing on promoting micro, mild and moderate hybrid by car, city bus industry, and further understand the key systems and components engineering technology. Also active in the whole mix, plug-in hybrid vehicle technology research and application, bring a breakthrough in battery technology and development, to effectively reduce fuel consumption, as the foundation for the transition to electric.

T10 is also preparing to promote joint enterprise batteries, motors and electronic control systems industry. By the T10 enterprises (some or all of) investment, state and local governments to give considerable capital investment and business cooperation with domestic and international benefits (or equity holding), critical systems and components involved in the development and industrialization, the formation of industry to meet demand matching capacity. Absorption edge of the auto parts business, to develop two to three annual output of 30 million units (sets) or more electric accessories manufacturer, to form the industry-wide electric vehicle supporting capacity.

Joint development of new energy vehicles and major assemblies of the validation and production standards. Standards for new energy vehicles to strengthen the system (repair) work to research the production of major enterprises as the mainstay, the joint promotion of the development of new energy vehicles and key parts of the production, testing and test validation criteria.

"Golden Sun" has been questioned support policies need to be improved

2011-07-14T03:19:00.000-07:00

"Golden Sun" has been questioned support policies need to be improved

"Golden Sun" issued on the occasion, was nearly ten thousand domestic solar companies to address the financial crisis last straw, however, due to loopholes in the mechanism, and the lack of supporting standards, the ultimate fear only come "nowhere near", or even on the "Golden Sun "rush of small photovoltaic business, or because of the uncertainty of the venture and eventually" burn "themselves.

Ten billion subsidy off "Stock Watch" tide

In the "Golden Sun" project implemented at the beginning of a declaration in the provinces to set off a big boom. According to policy, each province can declare up to more than 20 MW, Shandong Province, there are over 100 MW submitted to the province; and powerful solar business, often the size of a report on up to 50 MW .

In the "pre-emptive, first served" declaration boom, corporate fraud standard, the use of inferior products shoddy after another.

An industry source said: There are a considerable number of enterprises in order to obtain more financial subsidies, to take the "low buy high newspaper" approaches to improve the overall system cost, thereby obtaining subsidies. What is more, the direct use of subsidies does not meet the quality requirements of inferior products, waste time and even return the product abroad. It is understood that some silicon components supplier factories reported only 9.5 yuan per watt, thin film batteries reported only 6.5 yuan, the lowest production costs than the current 20 percent lower. Golden Sun project in this regard is that the contractor is to maximize corporate profits hard rock bottom price, the supplier to obtain the order at a loss; the other hand some components supplier to the original products of the secondary products, defective digestion in the inventory " Golden Sun "project in.

Heavy cost burden

In the current PV cost is still higher than the thermal power generation, photovoltaic power generation in the failure of the Government's tariff provides for the circumstances, "Golden Sun" project at the beginning, the industry has not fully expected corporate earnings.

The equipment, maintenance, construction and materials costs are included, according to the current commercial electricity 0.9 yuan / kWh price, a "Golden Sun" project payback is 21 years. Total investment in accordance with state subsidies for 50% of the cost recovery period can be shortened to 10.5 years in theory.

This is just a theoretical calculation, excluding rain, snow and cloudy days and can not generate electricity, in fact, less than 200 days throughout the year generating days, and also a day of power peak at 4 hours, the project payback period on even longer

In 2009, the financial crisis led to a great export market for photovoltaic products shrinking, so a large number of small and medium enterprises to become a photovoltaic "Golden Sun" project in the construction side, almost swept from the project application to all aspects of post-construction. In this process, companies often bear the majority of PV construction costs. With a registered capital of 10 million solar companies to count, to build a common need tens of millions of photovoltaic power plant costs have far exceeded the scope of its capabilities. This huge holes to fill one of the ways is to sell products. As a result, the tender default - has become the "Golden Sun" project can not declare a secret understanding. In addition, the tender part of the lack, in the face of the project will certainly have to lose money, many solar companies to find ways to cut costs, even cutting corners, shoddy.

Timely or harm than good

Last July 21, in the "Golden Sun works," when the introduction of subsidies, Suntech Power (STP.NYSE) shares rose the next day that crashed the day to close at $ 17.80. For Suntech, LDK such listed companies, this is no doubt that they fall into financial crisis, hardship, the time came to the rescue.

However, for more SMEs, Golden Sun is "timely", or blindly "harm than good," the poison is still unknown. Energy Technology Company in Hai Duong to apply to a four Golden Sun project, which is located in Fujian Lin Shing grid-connected photovoltaic power station a construction project has been started. However, the financial subsidies has yet to place the company has become the biggest worry. According to the Ministry of Finance list of online publicity projects, Citylink photovoltaic power plant a demonstration of the total size of 3 MW, which means about 87 million of the total investment. Currently, 50 percent of the financial subsidy, which is nearly 43.5 million of funds from central government to remain in the province, city or county issued financial step by step, in Hai Duong and the company has invested 20 million advance.

In fact, even if financial subsidies in place quickly, it only ensures that the project on schedule, but to really get "rich and famous", may have to wait for the pending electricity price will be announced.

Currently, the Ministry of publicity more than 200 "Golden Sun" project, the construction company's production capacity of 50 MW of the enterprises accounted for almost half. In other words, nearly 1 / 2 small solar companies face the same dilemma.

Industrial policy to be improved

Related industries have expressed the hope that the policy is the feed-in tariff subsidies.

From the "Golden Sun" It is obvious that the introduction of industrial policy would be "on paper." "Golden Sun" is basically the size of subsidies in accordance with each province divided into 20 trillion standard: take into account the differences between eastern and western regions, the eastern region is clearly not the western part of the land and light strengths. To Beijing, Shanghai, for example, want to find can produce 20 megawatts of solar production base of probably more than in the western desert much more difficult.

Moreover, the industrial policy of supporting standards, such as Golden Sun project acceptance criteria and is not sound, almost no post-regulatory measures, which gave the industrial implementation of the policy has left a huge loophole.

2010 battery industry forecasts and trend analysis of factors affecting

2010 policy to stimulate the economy and economic revitalization programs together, domestic demand will further turn for the better battery, at perhaps the world's economic recovery also led to foreign demand for batteries continues to rise, in 2010 China's battery industry will overcome the difficulties appear good growth .

1,2010 battery domestic market demand will rise slightly

Batteries are widely used in automobiles, motorcycles, electric bicycles, ships, trucks, rail vehicles, UPS uninterruptible power supply, lamp, medical equipment, electric toys, remote control, computer, cell phone, camera, MP3, radio, emergency lights, alarm devices, lights and other electrical appliances in. In the fuel tax reform, lower oil prices, cars to the countryside and other planning for the revitalization of the auto consumption policy, driven by China's automobile industry will continue to grow. According to the Automobile Association predicts that by 2010 China's auto output will reach 15 million, growth rate of around 10% this year, automotive battery market will rise, while other applications will not be lower than 2009 levels, we estimate that 2010 battery demand in the domestic market rose slightly.

2,2010 international market will rebound in demand for batteries is estimated to reach the basic level of exports in 2008, the export situation of China's battery will be improved.

Second half of 2009 the international battery market has been gradually recovering, and 2010 world economic recovery will further rise, the international demand for batteries will gradually enlarge the estimate of China's exports of up to 2008 levels.

3, the positive impact of the battery industry factors

(1) battery industry included in the "light industry restructuring and revitalization plan"

"Planning" on the battery industry, industrial restructuring and the focus given to the development, proposed the establishment of public innovation service platform, the establishment of National Engineering Research Center for the battery, the battery industry to promote mercury-focus button alkaline manganese battery technology, an ordinary zinc-manganese battery-free mercury, lead free, cadmium, lithium-ion batteries replaced nickel-cadmium batteries, button alkaline manganese batteries containing mercury out of 9 billion backward production capacity and other measures.

2010 policy to stimulate the economy and economic revitalization programs together, domestic demand will further turn for the better battery, at perhaps the world's economic recovery also led to foreign demand for batteries continues to rise, in 2010 China's battery industry will overcome the difficulties appear good growth .

1,2010 battery domestic market demand will rise slightly

2,2010 international market will rebound in demand for batteries is estimated to reach the basic level of exports in 2008, the export situation of China's battery will be improved.

3, the positive impact of the battery industry factors

(1) battery industry included in the "light industry restructuring and revitalization plan"

(2) the rise of trade protection, trade barriers to increase the export costs

United States and Europe the rise of domestic trade protection, trade barriers increased. EU "Chemical Bill", "Recycling batteries directive" and other environmental regulations are the trend of globalization, according to the EU's "Official Gazette" recently issued directive on batteries and accumulators for the battery in the lead, cadmium, mercury proposed more stringent targets requirements, and involve exorbitant cost recovery. REACH Regulation and RoSH instructions to improve battery registration fees and testing fees, substantially increased the cost of battery production and export cost of sales.

(3) lack of core technology, lack of industry standards

Due to lack of core technology, the scale of production of photovoltaic cells Although China ranks third in the world, still get out of the "two out" to earn a little money to the old model, and trigger a series of environmental pollution problems.

China's battery industry, especially mobile phone battery, there is no uniform standard, there are many security risks, following the mandatory standard mobile phone charger, the Ministry is developing a unified standard mobile phone batteries. As the cell phone battery is a source of profitable firms, uniform standards will be cut this part of the profits will lead to decline in the profitability of the battery industry, some companies are experiencing business difficulties, or even a loss.

(4) appreciation of the renminbi on the battery industry

RMB exchange rate from 2005 1:8.3, about 1:6.8 to adjust the current. 70% of China's battery production for export, the export price of RMB appreciation and the battery difficult to raise the cost of exports is significantly increased battery to enable enterprises to economic decline.

(5) Environmental management of investment continues to improve

Today in the promotion of green GDP, battery and environmental issues of wide public attention by the government. Enterprises to increase investment in environmental protection, increased operating costs.

In 2009 China's battery industry, although there is also the export downturn, inefficient, however, is to stimulate domestic economic policy and the role of economic revitalization program, the industry has bottomed out. With the overall improvement in the domestic economy and foreign economy stabilized in 2010, China's battery industry will enter a recovery. Crisis is a challenge but also opportunity, as "light industry restructuring and revitalization plan," the implementation of battery companies can seize the opportunity to adjust the product structure, strengthen technical, process and equipment innovation and accelerate the elimination of backward production capacity, quickly transform to a diversified direction; to produce efficient, environmentally friendly, energy-efficient transformation of the field battery, the battery industry to promote sustainable development.

The lowest volume of domestic PV

2011-07-07T21:09:00.000-07:00

The lowest volume of domestic PV

By the industry as a "father of solar energy," Professor Martin Green, in the just-concluded "Fourth International Conference and Exhibition on Photovoltaic Solar Energy", said: "China's solar energy industry should strive for higher quality, better selling the price. "

This exhibition, there were from Germany, the United States, Japan, France, Spain, Australia, 48 countries and regions, 1408 exhibitors to bring their latest technologies and products. Province a total of 142 photovoltaic exhibitors, displaying content, including raw material supply, the main and auxiliary materials, photovoltaic cells, photovoltaic modules, photovoltaic equipment and other engineering and photovoltaic applications.

Martin Green, the world's most renowned experts in the PV industry, one from the eighties, he was China's PV industry is very concerned about.

The end of 2007, China's solar cell production capacity has caught up with Germany as the world superpower.

In the province, one from the industrial production of silicon photovoltaic system development to a complete industrial chain has taken shape, but showing a "two small, the middle" of the distribution pattern of raw materials and markets overseas, most companies make the middle of the main processing profits.

However, the world's first production, does not mean control of the international right to speak. Fourth International Photovoltaic Power Generation spokesman Hong Chongen told reporters that China's solar cell selling price in the international arena is still the lowest. In 2009 the export price of China's solar cell is about 1.55 to 1.7 U.S. dollars / Wp (Wp: peak power output of solar battery units) between the fourth quarter of the price of an average of only $ 1.45 / Wp. "But the foreign price of solar cells are generally in the 2.0 $ / Wp or more."

Affect international sales prices for two main reasons, one of China's output ranks first in the world though, but for the solar, "the application of small countries." China New Energy Chamber of Commerce Institute Li Lei told reporters that China's solar cell production, from 438 MW in 2006 soared to 4100 MW in 2009, just three years, production increased nearly 10 times. But the end of 2009, China's photovoltaic power generation project has been built but only 300 MW, the country more than 90% of the PV modules are exported to foreign countries. High external dependence, increasing market competition.

Another more important reason is the uneven quality of products. In the entire PV industry chain, component manufacturing because less investment, short construction period, low technical and financial barriers, and other characteristics of the nearest market, attracting a large number of manufacturing enterprises, is the fastest growing PV industry chain one of the links . Currently there are more than 300 solar module production, assembly and excess capacity, but also led to the uneven quality and low value-added products.

Currently the province has built 4.93 MW photovoltaic project in the construction 35.44 MW, 4.75 MW of new construction in 2009. To promote the use of promoting industrial development, last year, the provincial government issued "to speed up the popularization and application of solar and other new energy and industrial development," and proposed the implementation of "one hundred plus a six base" program, solar and other new strategies to enhance the energy industry and a package of policy measures. Strive to 2012, the province's new energy generation capacity of 350 MW and achieve photovoltaic, wind power and other new energy consumption accounts for the province's total energy consumption of more than 1%, become an important new energy R & D and manufacturing equipment base level of technology reached the international advanced level.

Turning to the next step in the development of China PV industry direction, Martin Green, said even a few "Quality" (quality). In his view, many Chinese solar companies products are standard and there is no conversion circuit design not up to standard two major problems. To be more internationally competitive, by mastering the core technology to continuously improve product quality and added value is the "Fuji secret."

China's solar industry and strive to break through technical barriers

At present, China's solar industry had previously been dependent on exports, but under the influence of the economic crisis, are turning to the growing Chinese domestic market. As of January 2010, China has more than 10 domestic large-scale power stations start 1MW and above, in the future there will be more projects ready for implementation. The industry's attitude is "thin-film solar cells on the active challenge, and strive to overcome technical barriers." For businesses with their own technology, the field there is a huge business opportunity.

Shanghai Jiao Tong University in China in 2020, the amount of solar power into making a bold prediction: "will greatly exceed 20GW, also is expected to reach 200G ~ 500GW".

Reduce the cost of hydrogen fuel cell catalysts Bacheng

Technical University of Berlin researchers and scholars from the United States jointly developed a new platinum alloy, this new catalyst could save a lot of precious metals platinum, so that the chemical reaction of hydrogen fuel cell cost reduction 80%, the results of this study published in the latest issue of "natural chemical" magazine.

As one of the new clean energy hydrogen fuel cell, in addition to an alternative to traditional diesel and gasoline engines, but also widely used in power supplies, and portable electronic devices such as notebook computers. Hydrogen fuel cell works is an electrochemical process is actually in the process combining hydrogen and oxygen, releasing electricity and water will not cause any pollution to the environment. To make this process fast and efficient, you need a lot of precious metal platinum as a catalyst. However, platinum materials are expensive and scarce resources is, therefore, the development of hydrogen fuel cell research is the key to efficient low-cost alternative to platinum catalyst.

The researchers mixed the platinum and copper, and then removed from the platinum-copper alloy part copper, only a few nanometers in diameter spherical platinum catalyst particles of copper, platinum and copper particles inside this spherical copper, shell is only a few atoms thick platinum , thereby greatly reducing the amount of platinum used. The researchers confirmed that the copper-platinum metal by removal of part of the mix and the process of copper, platinum can make the surface of the catalyst alloy particle density of the arrangement of atoms much closer than the average platinum. This unusual structure of these particles reduces the oxygen atoms binding to make platinum alloy catalysts with better performance than the pure platinum catalyst, hydrogen fuel cell manufacturers to greatly reduce the cost.

The researchers further tests proved that the surface of platinum catalyst changes in the structure, you can optimize the catalytic activity. The project leader Peter Strasser pointed out that similar structural changes also apply to other precious metals, precious metals used to reduce the cost of the chemical process of universal significance. Researchers will further study other non-precious metals platinum and a combination of effects, in order to find a more excellent performance of the catalyst.

users can not replace the iPhone battery

Chinese companies for the introduction of Apple's iPhone, how to replace the battery issue, insiders said that this was mainly due to the special design of the iPhone battery, users can not replace the battery, replace the battery 710 yuan as the price is reasonable, it can not be said clear, but Apple's advance notice is the right move.

users can not replace the iPhone battery

Prior to the July 8, Apple China published in Chinese information, saying "if only because the iPhone battery storage capacity required the lowering of service, Apple could help solve, but when the iPhone will be in maintenance fee."

The service should be targeted at China Unicom version of the iPhone. Apple China explained that the information published, by accident or damage resulting from improper use of the iPhone can not enjoy this service.

Meanwhile, Apple China warned that the repair process will erase all data on the iPhone. Sync your iPhone with iTunes to back up contacts, photos, email account settings, text messages, and more, it is very important. If the repair process of the loss of information caused by iPhone, Apple is not responsible. In addition, Apple does not offer any data transfer service.

In this regard, there are familiar with the industry, said the iPhone, iPhone cell phone battery problem is an old problem, which was mainly due to a special iPhone battery design, users can not replace the battery, if the serious depletion of the battery, it needs to be sent to Apple repair .

Advance notice to replace the battery once charged 710 yuan

Apple said the Chinese company's information, the battery replacement cost, including taxes and fees, including a total of 710 yuan.

About the cost is high or normal, this does not clear, because Apple's products have always been expensive, such as an apple wireless keyboard to 628 yuan, while the Dell's wireless keyboard is also just 100 yuan; a function with the Apple Remote and Mic Ear Headphones have 628 yuan, but in fact very stylish Motorola headset as long as 100 yuan; an apple LCD computer monitor to 7998 yuan, compared with most brands of laptops are more expensive.

Earlier, in the United States, had sued the user to Oakland, California federal district court complaint said the iPhone battery charge and discharge has been scrapped after about 300, a battery usage time is usually less than a year.

Apple on its Web site later opened a special column to tell consumers how to extend iPhone battery life. "If you properly use and maintain, an iPhone battery after 400 full charge and discharge can maintain after the 80 percent of capacity," Apple website claims that "if the battery is fully charged batteries can not meet the need, you may consider replacing the battery . "

China solar cell industry

China's solar cell production to the rapid trend continues to expand in 2009 to 4382MW, estimated at more than 40% of the world. On has become the world's largest producer, and in the future will continue to expand in China solar cell industry, the author's interviews in China according to reports regularly. This paper intends to adopt in March 2010 held in Shanghai "SOLARCONChina2010" and set up a meeting and exhibition, the reader interpret the status of China solar cell industry and future development.

Solar Exhibition "SOLARCONChina2010" and set up the meeting and its "6th CSPV (ChinaSoGSiliconandPVPowerConference)" March 16, 2010 - 18 in Shanghai New International Expo Centre (SNIEC) hold. Not only will the field be seen out of the global economic crisis is the growing momentum of China's solar cell industry outlook, can read its future development.

2009 annual output of 4GW, more than 40% of global share

At the opening ceremony, Industry and Information Technology Department of Electronic Information Division, said Wang Bo, "China's solar cell production in 2009 reached 4382MW".

In 2008 more than 30 percent global share of China's solar cell production has been of concern to many people in the industry. Although the official 2009 global production has not been announced, but production in China over 4GW of view, many share the view that "more than 40% of global share."

Multi-crystalline Si production will expand

With the 2008 Si prices fell sharply in the past has been free to set foot in the multi-crystalline Si solar cell production with the disorder, has been gradually restricted. As a result, prices become stable in Si at the same time, the industry also began to have a down to earth feel.

On the other hand, taking into account the long-term growth, the Si production in China can only meet market demand in China is also about half. Therefore, the will to focus on long-term growth initiatives. Wang Bo, "the government is studying the company access to multi-crystalline Si production base, scheduled to be announced shortly."

On the production side, a number of equipment manufacturers at the show and set up the meeting and released to increase the capacity of multi-crystalline Si ingot furnace technology. Release device can be changed from its original capacity of 500kg to 800kg. Efforts in production, coupled with the orderly growth of government support for industry, Si crystal production in the future is also expected to continue to expand.

Thin-film solar cells are also steadily

China's solar cell industry, although in a previous production of crystalline solar cells, driven by rapid expansion, in fact, China's thin-film Si and CIGS thin film solar cells, the same can be said positively. Involved in thin-film Si solar cell manufacturing business for almost 60. Which is not only to their own technology based companies, but also a package of (Turn-Key) to import equipment to start business enterprises.

But in this exhibition, in addition to Zhejiang Chint Solar (Astronergy) active display and publicity, other vendors, only Baoding Tianwei Group (BaodingTianWeiGroup) and Best Solar tech (BestSolar) exhibited a few companies such as a thin-film Si solar cell panels. From manufacturers in meeting the release situation, although the thin-film Si-based manufacturing costs in general lower than about 10% crystalline, but the current conversion efficiency is low, not enough confrontation crystalline competitiveness.

About CIGS solar cells, universities, research institutes and enterprises and an important figure in setting the meeting brought together, launched a focused discussion. Although CIGS-based thin-film Si-based compared with is expected to achieve high conversion efficiency and low manufacturing costs, but acknowledged there are stability problems, currently under development.

Overall, the industry's attitude was "thin-film solar cells on the active challenge, and strive to overcome technical barriers." Although some companies did not participate in the show, but has used its own technology rather than importing expensive equipment, began producing low-cost thin-film Si solar cells. It can be said for companies with own technology, the field there is a huge business opportunity.

Attention turned to the Chinese domestic market

China's solar industry had previously been dependent on exports, but under the influence of the economic crisis, are turning to the growing Chinese domestic market. As of January 2010, China has more than 10 domestic large-scale power stations start 1MW and above, in the future there will be more projects ready for implementation.

Shanghai Jiao Tong University in China in 2020, the amount of solar power into making a bold prediction: "will greatly exceed 20GW, also is expected to reach 200G ~ 500GW".

Hydrogen fuel cell vehicles will become the second front in its own brand

2011-06-23T23:24:00.000-07:00

Hydrogen fuel cell vehicles will become the second front in its own brand

"Our research and development of hydrogen fuel cell prototype vehicle more advanced level of performance can be said that the international advanced level, but compared to the leader of the international level there is a large gap." Professor Wang Binggang that "this is a more objective evaluation. "king of the National Clean Vehicle Action Coordination Leading Group Expert Group, the 863" energy-saving and new energy vehicles, "Major Project Office appointed expert.

"Energy saving and new energy vehicles," a major high-tech project office is the Division of Science and Technology (863 Program Office of modern transport technology) under the jurisdiction of the project management agency.

Over one billion yuan by the state development funds to support the stimulation of domestic auto companies eager to join the hydrogen fuel cell vehicle research ranks.

In addition to SAIC, Chery, etc. in the "15" during the participation in R & D enterprise, the Foton has joined. SAIC also from the field of hydrogen fuel cell car into the passenger area.

Mainly short board - hydrogen fuel cell life

Research and development in hydrogen fuel cell car, the Roewe 750 as the basis of "Shanghai" brand fuel cell car is the fourth-generation Chinese-developed hydrogen fuel cell cars, China now represents the most advanced level. The hydrogen fuel cell power system by the Shanghai Fuel Cell Vehicle Powertrain Co., Ltd. developed.

And third-generation fuel cell vehicle "Beyond the Three" compared to "Shanghai" brand fuel cell cars, vehicle dynamic performance more robust and efficient. 0-100 km acceleration from 19 seconds to 15 seconds, one-time continuous hydrogen charging mileage extended from 230 km 300 km, maximum speed from 120 km to 150 km. In addition, its higher degree of integration, vehicle stability, reliability has also been further improved.

Also equipped with a fourth-generation power system of the Shanghai Volkswagen Passat, Chery Eastar have a top speed of 150 km, 0-100km acceleration time of less than 15 seconds, filling a hydrogen gas can travel 300 kilometers, these performance did not differ much with the international advanced level.

In addition, the Dongfeng Motor have also entered the field of hydrogen fuel cell vehicles. In August 2004, Dongfeng Motor in Wuhan Polytechnic University, the Elysee as a platform, developed a hydrogen fuel cell car - "Chutian One." It is equipped with a 25 kilowatts hydrogen fuel cells as power, top speed of 103 km, but the mileage is shorter.

Hydrogen fuel cell bus research and development, in early 2002, Tsinghua University as the lead unit, and Dongfeng Motor Corporation, Beijing Bus Plant's five units of the overall group, bear country "15" 863 fuel cell city bus developed by the project. Tsinghua University has set up a Beijing Qing Hua Tong Technology Development Co., Ltd. as the industrial carrier.

At present, the latest hydrogen fuel cell bus maximum speed of 90 km / h, a hydrogenation maximum mileage of 300 km, the engine power output of 100 kilowatts. Compared with international advanced level there is a large gap.

November 15, 2007, China's commercial fuel cell bus demonstration project started the second period, Shanghai will be bidding for three to six conditions of Shanghai city bus fuel cell buses, a two-year model run.

Experts suggest that China has independently developed a fuel cell bus, the Chinese government has invested a lot of money. Abroad, the high price of fuel cell buses in order to promote China's policies and regulations to establish standards, suggested that China's fuel cell bus demonstration runs can also be added to the ranks.

In the engine, vehicle control technology, the level of domestic and international advanced level despite the differences, but this is not the most important development of hydrogen fuel cells difficult. The key problem lies in hydrogen fuel cell and battery life issues.

Wang Binggang said that currently the stability of the hydrogen fuel cell is still life 2000 hours, well below the international seven or eight thousand hours. Battery life of less than 2 years, while Japan is the most advanced 3 to 5 years.

It is worth noting that multinational companies have been involved in a domestic fuel cell vehicles.

The second approach - collaboration with multinational

In 2004, SAIC and GM signed a strategic cooperation framework for clean energy automobile agreement, both sides reached an agreement: general "Hydrogen III" hydrogen fuel cell vehicles from the first quarter of 2005 in China, a two-year model run. General Motors in 2002 introduced the "Hydrogen-III", based on the Pan Asia Technical Automotive Center in GM's North American and German engineering staff under the guidance of a range of integration, and the Pan Asia Technical Automotive Center will be responsible for the car future operation and maintenance.

In 2001, SAIC and GM China's Shanghai joint venture between Pan Asia Technical Automotive Center, with regard to the Buick GL8 introduced a prototype fuel cell vehicle called the Phoenix.

2005 Fuel Cell Bus Commercialization in China demonstration project bidding, SAIC, General Motors has supported to participate in the project bid and offer was GM's most advanced fuel cell drive system. At present, Shanghai Volkswagen's Passat has been produced hydrogen fuel cell vehicles, and will participate in Beijing during the Olympic Games transport services.

Wang, former vice president of SAIC major general said, because the commitment of some 863 colleges and universities and not in time to seize the latest international technology trends, so SAIC's hydrogen fuel cell vehicle research and development is not entirely rely on 863, but also cooperation with multinational companies .

SAIC did not disclose the parties concerned in the development of aspects of what kind of cooperation. However, the reporter has learned that domestic enterprises in the electronic engine control, vehicle control technologies, both traditional energy sources, or new energy vehicles, in collaboration with multinational companies, such as co-developed with Bosch electronic engine control technology .

Reporters noted that SAIC and GM's agreement also includes "the development of China's hydrogen fuel cell vehicles to contribute to standards and rules," such provisions. So, do not rule out the use of SAIC GM hydrogen fuel cell vehicles in China to influence standards.

Lithium-ion batteries to accelerate the demand pull

2011-06-21T20:17:00.000-07:00

Lithium-ion batteries to accelerate the demand pull

Rising gasoline prices and increased consumer awareness of green has been the global automotive industry to re-examine its drive systems, rechargeable lithium-ion battery has become a hybrid electric vehicle (HEV) application of technology to the fore.

Analysts pointed out that from the viewpoint of the face of near-zero emission, hybrid electric vehicle (HEV) with a lithium battery sales in 2015 expected to exceed $ 500 million.

Currently, Rockwood Holdings, Chile Sociedad Quimicay Minera (SQM) Inc. and FMC Corporation is the world's largest manufacturer of lithium, lithium has been a lot of its effectiveness due to new applications.

1 Li-ion battery development prospects

Lithium in the lithium-ion battery applications has been recognized. The first phase of the cell phone application, each cell required about 1 / 10 ounce of lithium carbonate. The second stage is the application of portable computers, mobile phones required the use of lithium carbonate is about 10 times.

Plug-in hybrid electric vehicle (HEV) using lithium batteries, lithium required for the laptop with more than 100 times the amount of lithium.

Lithium-ion battery performance is expected to play a key HEV, plug-in hybrid electric vehicle (HEV) using the combustion engine and two electric drive system. HEV systems, including plug-in hybrid (PHEV), the system in use before the combustion engine, for storing enough power, battery power can be driven by a certain distance. In addition, the pure electric vehicle (EV) do not set the combustion engine, rely on battery power drive. Lithium-ion batteries is expected to make plug-in hybrid electric vehicle (HEV) to the price and performance compared to natural gas-powered car to be.

Although Nickel - Metal Hydride battery has been used in most of the HEV, but the battery and lithium-ion batteries compared to the chemical manufacturing, power larger and smaller. Toyota's Prius hybrid electric vehicle GM nickel - metal hydride battery-powered. Toyota said that by 2010 annual sales of 1 million hybrid vehicles.

Chemical manufacturers' investment plug-in hybrid electric vehicle (HEV) present opportunities for development. Rockwood has developed a proprietary technology conductive lithium salt, lithium salt of this conductive battery chemistry can help overcome some of the challenges. SQM with Europe, Japan, Korea and the U.S. producer cathode formed a commercial alliance to develop cars with lithium-ion batteries.

However, the auto industry into the mass production of HEV are still in the initial stage, the amount of lithium car battery is still small. Strong growth in other end-user demand and the right price, will continue to support lithium demand.

According to the forecast of Bank of America, Kevin McCarthy, HEV lithium battery sales will grow to approximately $ 600 million in 2015. Analysis, HEV lithium-there are more long-term development opportunities. It is estimated that by 2010 sales of about one million hybrid electric vehicles, 2015 sales will double. Kevin McCarthy is expected to Bank of America, 2015, revenues lithium battery consumption will account for nearly half the amount of electric vehicle batteries, lithium from 2007 total revenues of less than 1% in 2015 accounted for 1 / 4.

Rockwood company in 2007 from lithium carbonate, lithium metal and lithium compounds derived from the total revenue of about $ 450 million. FMC Corporation's lithium in 2007 sales of $ 210 million. And Rockwood's similar, FMC produced lithium carbonate and special general downstream lithium products. SQM is the world's leading manufacturer of lithium carbonate, in 2007 from the lithium and lithium derivatives revenues of $ 179.8 million.

Battery and pharmaceutical end-users together accounted for Rockwood's lithium supply about 40%. Analysts believe that the near term, demand for lithium pharmaceutical sector will be mainly affected by strong demand for butyl lithium and other battery applications of lithium hydroxide, lithium carbonate and demand driven.

Lithium battery consumption with HEV production is no great demand in the case has shown double-digit rates of growth. 2007 nearly 20% growth in demand expected in the medium term will continue to be higher than the growth rate of 10%.

In addition to battery applications, the speed of growth in the medium term, there was grease, oil with lithium hydroxide, glass objects and glass fusion with lithium carbonate, lithium carbonate and other air conditioning.

With lithium-ion HEV battery power accelerating into the commercial market, Johnson Controls-Saft battery company in January 2007 in France, the world's first large-scale production of the HEV battery production plant, and has been produced with Class Mercedes hybrid electric vehicle sign Lithium-ion battery supply contract, Class hybrid electric vehicles in commercial production in early 2009. Japan's NEC Electronics to the 2009 annual production of 13,000 lithium-ion batteries by 2010 will expand production to 6.5 million units, to apply to the Nissan hybrid electric vehicles.

Some car manufacturers use lithium-ion battery-powered hybrid electric vehicle program being developed. Tesla Motors was the United States in March 2008 to begin production 2008 Tesla Roadster hybrid electric vehicles, will launch the 2009 models. Toyota and Matsushita's joint venture Panasonic EV Energy Company in 2009 limited production vehicle lithium-ion batteries in 2010, will shift to mass production.

Other lithium-ion battery manufacturers, including South Korea's LG Chemical Company, the Company and Hyundai Motor Co. signed a contract, from July 2009 onwards the company Accent hybrid electric vehicle supply lithium-ion battery. Saturn's PHEV and GM Volt EV mass production in 2010. Sanyo Electric Company will begin production of 1.5 to 20,000 / year lithium ion battery for HEV use in 2011. Volkswagen's hybrid electric cars in 2010 using the Sanyo Electric Company lithium-ion battery technology.

2009 lithium-ion rechargeable battery market was formally established. This is because Japan and overseas car manufacturers have started in the passenger cars on the lithium-ion rechargeable battery. Manufacturers in Japan, Toyota Motor, Fuji Heavy Industries, Mitsubishi Motors has decided to adopt, and in Europe, Daimler also said that use. In addition, Nissan, Audi, General Motors is also ready to use in 2010.

Decided to hybrid (HEV) and electric vehicles (EV) performance of the most important changes will occur rechargeable batteries. Reason is that Toyota, Nissan and other Japanese top manufacturers launched later in 2009 with a lithium-ion rechargeable battery models.

Objects involved in HEV, EV, plug-in hybrid (PHEV) and other fields. Toyota said it will start in 2009 in a subsidiary - Panasonic EV Energy small batch production for the PHEV lithium-ion rechargeable battery, start mass production in 2010.

2000 "Tino Hybrid" style on the first lithium-ion rechargeable battery with Nissan in 2010 with mass production of lithium-ion rechargeable battery HEV and EV. HEV is scheduled for rear-wheel drive car, the gearbox is now open and the tap in the baggage compartment is equipped with lithium-ion rechargeable battery. The batteries will be Nissan and NEC, NEC Tokin, a joint venture Automotive Energy Supply (AESC) provides.

In addition to Toyota, Nissan, other major vendors are also expected to use lithium-ion rechargeable battery. Fuji Heavy Industries, mass production scheduled in 2009 to "Plugin Stella Concept" for the prototype EV, Nissan will be the same car, using the AESC manufactured batteries. In addition, Mitsubishi Motors will also purchase and GS Yuasa Corporation (GS Yuasa) and other joint venture Lithium Energy Japan (LEJ) made battery, in 2009, mass production EV "i MiEV".

Honda plans new HEV models added in 2009, and in 2010 in the "Fit" in additional HEV models, but has not yet shown on the HEV in the general use of lithium-ion rechargeable battery. However, the company in November 2008 in Japan began to rent out the fuel cell hybrid vehicle "FCX Clarity" is equipped with a lithium-ion rechargeable battery, replace the capacitors had been used.

Overseas manufacturers, the Volkswagen Group in Germany scheduled for 2010 Audi listing HEV, including lithium-ion rechargeable batteries, Sanyo Electric Co. will start mass production from 2009. The General Motors decision to the HEV market in 2010, the lithium-ion rechargeable batteries will also be Hitachi Vehicle Energy (Hitachi Vehicle Energy) from the end of 2009 mass production.

2 lithium production increase continuously

Rockwood, SQM, and FMC's lithium production accounted for about 3 / 4, some of China's lithium production of small producers account for about 1 / 4. SQM's production is about 35% of the global lithium carbonate supply. Rockwood's specialty chemicals business through its Department of Chemetall's lithium carbonate about 30% of world production, and FMC Corporation production accounts for about 5% to 10%.

In 2009, the world's lithium resources consumption is 8 tons, is expected after 5 years, the United States alone 10 million lithium car demand will consume 10 million tons of lithium resources. Since 2005, lithium prices soaring by more than 10 million per ton in November 2009 rose to more than 60 million per ton.

In 2008 the world production of lithium (in lithium carbonate equivalents) estimated at 80,000 tons / year. The status of the global lithium carbonate industry, the resource threshold high, capacity is highly concentrated. As of the end of 2008, total global demand of about 95,000 tons of lithium carbonate, a major international manufacturer of Chile's SQM, FMC and the United States, Germany Chemtall total annual capacity of 79,000 tons, accounting for 80% of global market share. Since large-scale production of lithium carbonate enterprises must have abundant reserves of lithium salt lake resources, mining rights, which makes the resources of the industry with higher barriers to entry; the other hand, the vast majority of the world's resources are high magnesium salt of lithium-based low- , and from high-Mg low lithium brine separation of lithium carbonate purification technology is very difficult, just before these technologies lies in the hands of a few foreign companies, which makes lithium carbonate industry, but also provides many technical barriers. Therefore, creating a global lithium carbonate industry oligopoly structure.

Three major supplier of lithium from the "Li-triangle" (Argentina, Bolivia and Chile) to produce lithium brine storage. SQM and Rockwood's from the Salar de Atacama region of Chile production of lithium, the advantage of lithium at high concentrations and high evaporation rates, in the production process can use solar energy. In addition to outside of South America, Rockwood companies are Silver Peak, Nevada, brine production by lithium.

FMC Corporation from Salar de Hombre Muerto in Argentina storage of brine in the production of lithium, a filtration process, the filtration process faster, but higher costs than other processes.

Previously, Li Li-hui quarry sediments from the extract. Through this process, however, to produce, due to low purity, require multiple extraction steps and is energy-intensive process. China is now only used in the production of spodumene from a large number of lithium carbonate.

South America's storage capacity is still expanding. SQM's lithium carbonate production capacity being from 3 million tons / year expanded to the third quarter of 2008, about 40,000 tons / year. If market demand is strong, will also be expansion to 60,000 tons / year.

Salar de Uyuni, Bolivia has about 5.5 million tons of lithium storage.

Admiralty Resources Inc. plans to develop Argentina's northern Rincon Salara brine mine, mine has 10,500 tons of lithium carbonate equivalent. All the world's supply of lithium carbonate production will be about 20%. The company's goal is to put into production in 2009. 50 tons / year pilot plant was put into operation in April 2008.

Present from the "Li-triangle" of economic production of lithium is still a big cost advantage. However, rising prices are contributing to the development of lithium storage outside of South America. Norwegian mining company Nordic lithium in Finland through the acquisition of development projects for Europe's first manufacturer of lithium battery industry. The company expects production in Finland in 2013 3300 tons / year of lithium carbonate. Esmeralda County, Nevada, USA has the prospects for the development of lithium brine mine, Black Pearl, including mining companies will develop in California, Nevada and Utah's Great Basin, including lithium brine mine.

The first 20 years, Chinese manufacturers have also implemented a production. China in 2007, total world lithium market is about 1 / 4. The next 2-5 years, China will greatly expand capacity, production capacity is expected to have more than doubled.

Lithium-ion battery sources of raw materials in China is extremely broad. China is the world's lithium resources in the country, especially in the salt lake in Qinghai and Tibet have a lot of lithium resources, development of Salt Lake not only for low-cost lithium-ion battery materials, but also conducive to the development of the western region. At the same time, manganese, iron, vanadium, and phosphorus-rich resources in China are. Permanent magnet synchronous motor with a small, light weight and high efficiency characteristics, and China is big country of rare earth permanent magnetic materials for lithium-electric cars provided the material guarantee.

China has been found in the Qaidam Basin, lithium brine mine, but China mine brine concentration is low, so that China's lithium production SQM and Rockwood price than the company to more than double.

Lithium Salt Lake in independent research, provides technical and production process of magnesium on the basis of some of China's large industrial enterprises in recent years in the Saline Salt Lake and began building the depths of the Qaidam Basin, lithium carbonate, magnesium hydroxide and other chemical production base. Current domestic production of lithium carbonate mining company focused on Tibet, CITIC Guoan, Western Mining Group, Qinghai Salt Lake Group, the four companies, and mining in Tibet and CITIC Guoan has accounted for the majority, the two companies in 2008 lithium carbonate Total output of not more than 4,000 tons.

October 12, 2009, Toyota Tsusho Corporation (hereinafter referred to as Toyota Tsusho) and China CITIC Guoan Information Industry Co., Ltd. (CITIC Guoan) signed a letter of intent, the two sides will cooperate in the production and sale of battery grade lithium carbonate and downstream products . Toyota Tsusho is the Toyota Group in automotive related business trading company; CITIC Guoan is a listed company CITIC Group, the West now has taijnar Qinghai Salt Lake, an area of 570 square kilometers, is a liquid lithium-based mining large deposits of lithium carbonate in resources outstanding. This is a new signal that the competition of new energy vehicles have been advancing to the upstream resources.

China Tibet Economic Commission announced in late August 2008, Tibet will expand the resource base of China's largest lithium Zabuye Salt Lake, their investment will reach 1.084 billion yuan. After the completion of the project, annual sales income will reach 639 million yuan, profits of 200 million yuan. The expansion project will be a lithium salt and 5,000 tons / year, based on the construction of the lithium salt 20,000 tons / year, lithium chloride, 5,000 tons / year, lithium 500 tons / year high purity lithium 200 tons / year, material of lithium 30 tons / year and other lithium compounds, 490 tons / year production capacity. Salt Lake is located in Xigaze Zabuye Zhongba County, is the world's known resources of more than three lithium salt is one megaton of large, its surface brine, intergranular brine and solid minerals inclusive of lithium carbonate, The total reserves of 2,466,300 tons. Which only the surface to control the economic base of brine reserves reached 704.1 thousand tons, the amount of lithium resources in China ranks the first.

Information, is located in the hinterland of the Qaidam Basin in Qinghai Plateau is rich in potassium, sodium, magnesium, lithium, boron and other mineral resources, including magnesium chloride 3.1 billion tons, accounting for 99% of the country to maintain reserves; lithium chloride nearly 14 million tons, accounting for country to maintain reserves of 83%. In early 2007, Qinghai CITIC Guoan Technology Development Corporation West Lake taijnar tons of lithium carbonate project put into production in the Qaidam Basin, the West Lake taijnar become an important production base for lithium carbonate.

In addition, China's largest mining brine has a high magnesium / lithium ratio, processing may be more complex.

Allegedly, hybrid electric vehicles or pure electric vehicle batteries and other applications of lithium demand will continue to grow. Demand in the current rate, the global supply is expected to meet in 1775, the Salar de Atacama in Chile, with 6.9 million tons of recoverable lithium, Salar de Uyuni in Bolivia has 5.5 million tons of recoverable lithium.

Jiangxi new lithium energy industry base in the November 17, 2009 the park opened in Yichun City of Jiangxi Province. It is the nation's first lithium industrial base, Yichun in three years to fight the Asia's largest lithium production base, five years to fight the power of China's largest lithium production base. Jiangxi Yichun the world's largest lithium mine, now proven recoverable reserves of lithium oxide is 110 million tons, accounting for 31%, accounting for 12% of the world, with a good amount of resources, Yichun "lithium industry" is incredibly . It is understood that the country's first lithium industrial base, planning area of 20 square kilometers (30,000 acres), the United States has new energy, the Chinese home, Foster and more than 20 projects signed lithium admission, signed the contract funding of over $ 10 billion. In the future the development of lithium industry is expected to develop objectives are divided into three stages: 2009 to 2012, industrial output value of new energy lithium strive to reach 8.0 billion before the end of 2012; 2013 to 2015, new lithium energy industry beginning to take shape, and strive to the end of 2015 the output value of 300 billion yuan the previous year; 2016 to 2020, formed a relatively complete new lithium energy industry cluster, and strive to the end of 2020 exceeded 100 billion yuan output value of the previous year.

Photoelectric conversion rate of up to 100% new solar cell R & D success

California Institute of Technology recently developed a new solar cell, whose basic principle is to thin the silicon wire array embedded in the polymer substrate.In addition to thin flexible, the absorption of sunlight and its conversion efficiency have made a significant breakthrough.In addition, traditional solar cells required amount of expensive semiconductor material compared to this new type of solar cell requires only a small part.

Applied physics and materials science professor Harry Atwater and the Howard Hughes said: "The first time the traditional solar cells, light absorption material in light-harvesting limit." A new type of silicon used in solar cell arrays on a single line absorption wavelength of incident light 96% of the full wavelength sunlight capture rate of up to 85%.

Atwater said: "A lot of material to capture light very well, but it can not be converted into electrical energy, such as black paint for solar cells, the absorbed photon is converted to electrical loads can sub (charge carrier) is also very important." their R & D line array of silicon solar cells can be absorbed photon 90-100% conversion to electronic.Technically, this array has a near-perfect internal quantum efficiency (internal quantum efficiency).

Atwater concluded: "The high light absorption and better conversion capabilities achievement of this high-quality solar cells."

Silicon in the silicon wire array length of 30 to 100 microns (micron) between the diameter of only 1 micron.Equivalent to the thickness of the silicon wire array length, but the view from the corner of an area or volume, only 2% of this material is silicon, the other 98% of all polymers.As the traditional silicon solar cells is a very expensive component, so that only the traditional to 1 / 50 of solar cell production costs will be much lower.

How to keep up with new energy vehicles in China Kam American and Japanese models developed

2011-06-14T20:16:00.000-07:00

How to keep up with new energy vehicles in China Kam American and Japanese models developed

In fostering domestic consumer market, learn from the U.S. government stimulus

Research on key technologies in the learning mode of the Japanese R & D production and research alliances

Further clear road map for China's new energy vehicles, change the status quo has been wavering

Not only for the "Beyond" and give up efforts to improve the traditional internal combustion engine

This is a pure electric buses to replace the battery "gas station." Currently, Beijing has 100 electric vehicles and 870 hybrid cars. Xinhua News Agency reporter Li Wenshe

At present, Chinese auto companies have been competing to set off a wave of new energy vehicles repairer, however, new energy vehicles in China but in reality there is a lack of supporting infrastructure, consumer market, immature, and other key technologies difficult obstacles. The future of new energy vehicles in China will have huge market potential, experts suggest that the development of new energy vehicles in China to learn from the United States should stimulate the development of model policies and Japan.

Forces from fighting each other to find

As the energy crisis, environmental needs and national policy support to encourage a variety of factors, in the current Chinese auto manufacturers, whether it is local brands, or joint ventures, are trying to join the production of new energy vehicles or planned.

Reporters learned that in previous years, the development of new energy vehicles to the main difference is that business alone, has emerged between government and enterprises to jointly develop new energy vehicles momentum. Guangzhou Municipal Government and Nissan Motor Co., Ltd., Dongfeng Automobile Co., Ltd. signed the "electric car industry to jointly promote the Memorandum of Understanding." Nissan electric vehicle development at the forefront of the industry has come on, Guangzhou will be the development of new energy vehicles as an opportunity to guide the future development trend of automobile, further enhancing the government and the intensity and level of business cooperation, and promote the development of new energy vehicles in Guangzhou.

Guangzhou Municipal Committee, Deputy Mayor Wu Perseverance, Agility said that with the rapid development of automobile industry and the rapid growth of car ownership, resources and the environment face increasing pressure to develop new energy vehicles will be the inevitable choice Guangzhou automotive industry to achieve industrial upgrading and sustainable development an important way. In order to accelerate the development, Guangzhou has set up a leading group for the development of new energy automotive industry, and to study new energy automotive industry development programs. Guangzhou economy looking forward to the smooth introduction of zero-emission vehicles for the development of local economy and building a green home to make a positive contribution.

Whether international capital, and domestic enterprises, are very optimistic about China's auto industry in this new energy giant cake. Industry experts predict that by 2020, 10% -20% of China's passenger car sales will come from pure electric vehicles, plug-in hybrid and other new energy vehicles.

Ministry also made a number of cities selected energy-saving and new energy vehicles running large-scale demonstration of the idea, for three consecutive years in the country more than 10 large and medium cities of conditional level one thousand hybrid vehicles, pure electric vehicles and fuel cell vehicles and large-scale energy supply infrastructure model, and strive to make the country the scale of the operation of new energy vehicles in 2012 accounted for 10% of car market share. The core of this vision by expanding the scale demonstration of new energy vehicles to promote the industrialization process.

Development model of advanced foreign

While the broad market prospects, but the new energy vehicles in China but in reality there are charging stations and other infrastructure facilities lack mature consumer market, and other key technologies difficult obstacles. Data indicate that the current utilization of new energy vehicles in China is only 1%. Changes in China's new energy vehicles, "Game No One Played" situation, experts suggest that the policy should be to learn from the United States and Japan to stimulate R & D model.

First, cultivate the domestic consumer market.

"Although the new energy vehicles, energy-saving environmental protection, but at the same level model comparison, the price at least higher than the five or six million. More money to buy a car or spend more money to buy oil, Chinese consumers tend to choose the latter."

China's new energy into the earlier hybrid car market - - the Toyota Prius, for example, in 2006, car sales in China 2100, 2008, in order to enhance sales, price 24000 yuan Toyota initiative, but sold only 899. Large relative to the global total of 1.2 million sold the brilliant record, the Prius performance in the Chinese market it is deserted.

Jia Xinguang industry expert consultants in Beijing that the promotion of new energy vehicles urgently cultivate the domestic consumer market, leading the government plays an indispensable role in the meantime, the key is to increase the intensity of industrial subsidies, the subsidies directly benefit consumers, effectively stimulate consumption . Stimulation of the United States policy in this regard is worth learning.

According to reports, the U.S. government and enterprises using the two-way interaction. Obama fuel restrictions and a new energy policy for the U.S. auto industry, a clear direction, the enterprise will speed up its own research and development. The United States through the development of more stringent emission standards for vehicle fuel policies and new energy vehicles, as well as through government procurement, energy efficient cars, consumers to buy efficient cars tax cuts, the creation of new energy vehicles in the government-funded projects, investment promotion, infrastructure construction of new energy vehicles and other strategies , the U.S. government to further promote the automotive products in the "small" and "low energy" direction. The federal government will purchase from the U.S. Big Three auto makers produced 17,600 vehicles, including new energy, including energy-saving vehicles.

Obama made it clear that, by 2015 the United States to have 1 million plug-in hybrids on the road. To encourage consumption, purchase plug-in hybrid business owners can enjoy the $ 7,500 tax deduction. Also, the Government has also invested four hundred million dollars to support the construction of infrastructure such as charging stations. These new energy policy, more specifically the development of new products, energy saving direction and goals.

Second, build a production and research union.

New energy vehicles to overcome many of the key technical problems, thus strengthening joint research and development and improve the development of new energy efficiency is an important part of facing the vehicle development.

"China Automotive News" editor Zhong Shi said: "Now the development of domestic enterprises enthusiasm of new energy vehicles, which is very positive initiative, we can not 'mess' on the grounds, the refusal of most companies outside of new energy vehicles, industry organizations should play, the role of local government, strengthen the organization and guidance, collaborative research, division of production, government departments should organize a national automotive industry and interested in the development of new energy vehicles companies plan to jointly research and development, in particular, to encourage more enterprises, universities, research institutes and even individuals to participate in the development of new energy vehicles cause, to appear full steam ahead of new energy vehicles good situation. "

Zhong Shi also proposes a need to guard against the phenomenon of domestic enterprises to develop new energy vehicles enthusiasm, but many businesses split up R & D, low efficiency, high cost, as well as the business is to get state subsidies to the new policy launched energy vehicles, aimed at grabbing the money without the repairer. "Thus, new energy vehicles in China in the research of key technologies, we should learn from Japan's University Alliance R & D model that is conducive to integration of resources, and it helps control the flow of corporate subsidies."

According to reports, Japan's key technologies to overcome the battery, has established a high-performance electric vehicle battery development of the largest new energy automotive industry alliance to jointly implement the 2009 "innovative cutting-edge basic research battery of special" new project. The consortium includes Toyota, Nissan and other auto companies, Sanyo Electric and other motor, battery manufacturers, and Kyoto University and other famous universities and research institutions, a total of 22 members of the unit. Each unit of the Union out of more than 50 professionals engaged in cooperative research and development of basic technologies common business needs. Japanese government plans to invest within seven years of 21 billion yen for this project, through the development of high-performance electric vehicle batteries, in 2020, the Japanese electric vehicle on a single charge of driving range more than tripled.

Third, to establish a clear road map.

Tianjin University, China Automotive Research Center, deputy director of strategic development Guo Yan pointed out that the road map for new energy vehicles in China has been slow swing is an important reason for its development. According to reports, the international strategic direction of new energy vehicles, the current consensus is: the starting point is the traditional gasoline and diesel vehicles, the end is a hydrogen fuel cell vehicles, during a transitional period of 20 years or so, it will be the new energy model their quarter scuffle for the war. Focus on developing hydrogen-powered cars with the United States, Japan and vigorously develop gasoline-electric hybrid, diesel-powered cars in Europe compared with main attack, China's new energy roadmap has been unclear.

Participated in the strategic development of new energy vehicles in China's Automotive Safety and Energy Director of State Key Laboratory of High-Ming Ouyang said, "After the hair belongs to the Chinese automotive industry: one car behind the traditional engine technology multinational, on the other hand is also behind the development of new energy technologies in the car of state. Therefore, China's automotive research and development of new energy technologies must be different from other countries, it can not be the order of development, and to Sarkozy heads together. "

Fourth, diversification of energy-saving vehicles.

Industry experts also pointed out that application of a wide range of perspective to the development of new energy sources. Because in the energy, the human's ultimate goal is to achieve sustainable use of renewable energy development. Renewable energy including solar, wind, hydro, biomass, geothermal energy, tidal energy, etc., short-term goal is to reduce dependence on fossil fuels to achieve energy diversity.

Jia Xinguang analysis that, at present, the industry's eyes are on the outside of the electric vehicles, hybrid vehicles. From the market, supporting the need to address the energy supply network (charging station), the performance to meet the needs of consumers, the price to be competitive. If the building through a large number of coal, fuel power plants to provide electricity, resulting in new pollution, the new energy vehicles not to pursue the matter whether, and if you want to solar, wind, nuclear power to increase the power supply, power generation is now the "new energy" , experiencing the pain of suffering the high cost, technically not completely break. Even if the electric vehicle technology improved, the new generation of energy technology will not immediately mature.

Jia Xinguang, said the public had developed a hundred kilometers a liter of fuel concept car, though many are skeptical of this car, but with this car, we can also see a wide range of fuel-efficient technologies: low-drag and efficient internal combustion engines, reducing weight, body of new materials, etc., so in a traditional internal combustion engine has much to do energy saving and emission reduction. China's rush to development of electric vehicles is to "leapfrog development" and "beyond", which gave up efforts to improve the traditional internal combustion engine, resulting in a new passive: the new energy vehicle market has not really taken shape, but also the development of highly efficient internal combustion engine great potential, we do not account for both sides.

"The car will not only run in a way, not only has highways, as well as first, second, easy road, as well as rural roads. Similarly, the development of new energy vehicles is not only one way, especially the realistic way to go . "Jia Xinguang said.

Lithium-ion battery management system design

This article discusses the power lithium battery management system is designed to achieve the power of lithium battery overcharge protection, over discharge protection, overcurrent protection and equalization charging functions.

Introduction

The extensive application of lithium-ion batteries for more than ten years, but early days for mobile phones, laptop computers, cameras, DVD and a series of small mobile electronics, such occasions are often single-string to use, low load current, high safety factor. The last two years, lithium-ion batteries for its lightweight, high energy density, no pollution, has started in electric bicycles, power tools and power toys, rapid application areas, and gradually applied to the field of hybrid and electric vehicles. However, the safety of lithium-ion battery power is still one of the most concern now, so their conservation is very important. In addition to lithium-ion batteries to ensure continuous improvement of their own security, must be of the battery management system, the battery and its application to balanced development. Lithium-ion battery protection including over charge protection, over discharge protection, over current and short circuit protection.

1, the function of protection circuit

1.1 Overcharge protection

Of lithium-ion batteries, which charge the highest single energy-saving core voltage must not exceed the specified value, or the battery electrolyte will be decomposed, making the temperature rise and produce gas, reducing the service life of batteries, serious or even cause an explosion Therefore, we must guarantee protection circuit can not be over-charging, the battery must be in each section to monitor the battery voltage, when the batteries when the voltage exceeds a set value, that is activated over charge protection, protection circuit cut off by the charge loop, stop charging. Voltage in the batteries and return to allow the lifting of overcharge voltage lock mode to stop protection. Different materials, lithium-ion battery voltage and the release of its protection voltage values have different requirements.

In addition, attention must also be produced by malfunction due to noise, in order to prevent the miscarriage of justice and misuse, but also set the overcharge protection delay, and delay time can not be shorter than the duration of the noise. When the voltage overcharge detection voltage continuously over more than a certain time to trigger overcharge protection.

1.2 Over-discharge protection

Excessive discharge of lithium-ion battery will shorten its life, and damage the battery is often irreversible. In order to prevent over-discharge of lithium-ion battery status, when the lithium-ion battery voltage is lower than the over-discharge voltage detection point, over-discharge protection is activated, suspended discharge, and will keep the battery low quiescent current standby mode, parameter setting off similar sufficient protection.

1.3 Over current / short circuit protection

The largest lithium-ion battery discharge current is limited and excessive discharge current lithium batteries also can cause irreversible damage, affecting their life.

Short-circuit current protection to protect this function is an extension, if the short-circuit due to external causes such as high-current discharge to immediately stop the discharge, or on the lithium battery itself and the external devices may cause serious damage.

Over-current protection delay time is normally at least a few hundred microseconds to milliseconds, while the short-circuit protection delay time is microseconds, almost instantly cut short the circuit to avoid the huge short-circuit the battery injury.

To power tools, the protection of current value and set the delay time and power tools must also be combined as the parameters, otherwise it will affect the tool's output torque and motor life.

1.4 cell balancing

Power lithium-ion batteries are generally required to Ji Chuan, dozens or even hundreds of strings above the string, because the battery in the production process, from start to become a finished film to go through many procedures, even after rigorous testing procedures, so that each power voltage, resistance, capacity consistent, but the use of a period of time, the battery internal resistance, voltage, capacity and other parameters fluctuate, forming an inconsistent state, it will have this or that difference. This difference reflected in full or discharged battery when the voltage between the battery cells in series is not the same. This situation led to the process of charging the battery pack, the battery voltage is too high trigger early cell battery overcharge protection, and in the process of discharging the battery cell voltage is too low result in battery discharge protection, so that the overall battery capacity decreased significantly, reflected by the battery capacity of the battery pack in the worst performance of the capacity of the battery cell, and use are prone to the phenomenon of overcharge and over discharge, and are not easily found, leading to early failure. Therefore requested to complete the battery cell protection circuit for the balanced operation for high voltage batteries from taking excess current, excess consumption of electricity, to achieve cell balancing to maximize the effectiveness of lithium battery power, extending battery life and increase security. The balance of the current methods commonly used storage balance and resistance balance.

Equilibrium is the use of battery energy storage inductor or capacitor energy storage components such as charge and discharge through the relay or switching device without energy storage components to achieve balance between the battery switch to the energy transfer between cells. This method of balancing the general control network charge complex, high-security management requirements, in the use of energy storage devices should be careful to take a good charge and discharge time, its biggest advantage is that charge and discharge (work) in use, can balance the unit cell function, and does not consume power lithium-ion battery pack.

Resistance is generally balanced by resistance network controller on the battery pack off balance diversion, this method can be balanced multi-cell control simple. But the balancing process in the election if the resistance is too large, the equilibrium current is too small, had little effect; If the resistance is chosen too small, the resistance power of large energy loss system big, balanced, low efficiency, high system thermal management requirements the need for temperature measurement and control.

Resistance is the principle of equilibrium in the battery charging process, when a fast battery charging, the battery voltage is higher than the other, the system balanced by controlling the switch conduction resistance of the shunt and reduce the battery charging rate, in order to achieve sections the purpose of equalizing charge the battery.

2 Implementation of protection

For the protection of lithium-ion batteries have two main methods: microprocessor control and integrated circuit chip.

2.1 IC control

The current lithium-ion battery can chip a lot of protection, foreign countries, Taiwan and mainland China have a variety of chips to choose from, the current Japanese Ricoh Seiko adopted by more programs, programs mature, the external circuit is simple, but the price is more expensive.

IC implementation of various protection features almost the same, the protection mode and the external lines are also similar, in practice may need to select a different IC. Select IC's time to consider multiple, different types of IC overcharge protection voltage is different, there is also 4.35V 4.25V, there IC's own power, whether the peripheral circuit is simple enough, the various parameters of the protection IC is meet the requirements, the volume is small enough to be considerate.

Protection board in addition to other protection function, low power consumption are also important parameters. To prevent over-discharge protection IC to detect the battery voltage, over discharge detection voltage once they reach the following, you must turn off the power MOSFET and the cut-off discharge. But this time there are natural discharge the battery itself and the protection of IC current consumption exist, so need to protect the IC to minimize current consumption, in the protection of state, the quiescent current consumption must be small 0.1uA.

Another power lithium-ion rechargeable battery pack for work or the instant when the pressure will be generated, thereby protecting IC shall meet the requirements of high pressure.

Figure 1 is a Seiko S-8254A 4-string for the protection of IC application schematic. S-8254 series built-in high accuracy voltage detection circuit and delay circuit is used for 3 or 4-cell lithium-ion or lithium polymer rechargeable battery protection IC. Switching through the SEL pin, can be used to protect three or four series cells.

Figure 1 S-8254A 4 serial protection schematic

Of course, the current battery protection IC to protect the four most common lithium-ion batteries, but many applications require more than five working lithium-ion batteries in series, such as power tools, electric bicycles and UPS, at this time how to solve it? Shown in Figure 2, the circuit can 20A/24V output power, to Seiko S-8254AAV control chip as an application example, it uses two chips in series with the protection, protection of lithium-ion battery pack 8-string, too discharge protection voltage of 2.70V +/- 0.080V, overcharge protection voltage is 4.250V +/- 0.025V.

Figure 28 Series power lithium-ion battery protection circuit

The circuit balance control with R5408 chip, a high voltage measurement accuracy, balance current up to 1A.

2.2 MCU control

Protection of some of the existing integrated circuit chips mainly for the following 4 cell battery power-saving protection, and for four or more batteries than a single-level protection can be used in series or in-chip multi-level protection IC of several series way. But the use of multiple protection chip series way more than 4 cell battery power-saving protection circuit poor scalability. Meanwhile, the integrated protection of the chip is often only for one or more of the characteristics of a class of cells, the lack of flexibility, cost often higher. This, combined with lithium-ion battery charge and discharge characteristics of lithium-ion battery power on many occasions protection circuit, using the MCU (microprocessor) as the core design.

Control various functions of the microprocessor as the core, in addition to lithium-ion battery pack provides over charge, over discharge, over-current protection, effectively within the lithium ion battery lithium single charge and discharge provide dynamic equilibrium, the temperature protection, short circuit protection, and can provide, such as capacity forecasting, communication, identification and other functions.

3 anti-interference measures of hardware

Lithium-ion battery management system as part of an application system, and are subject to various electromagnetic interference, the actual work environment is relatively poor, it was necessary hardware and wiring on the PCB board to take certain anti-interference measures.

4 Other Requirements

Because the battery is primarily used to supply the main application project, thus requiring only a very low power consumption BMS.

5 Conclusion

Lithium-ion battery power monitoring is a relatively new subject, its management system will be integrated monitoring protection technology design, with the rest of the battery pack, charge, discharge, management, and automatic maintenance and other basic functions, to achieve practical and reliable requirements.

Patented technology into starfish Tech main power battery 2 times increase in output value

2011-06-10T20:00:00.000-07:00

Patented technology into starfish Tech main power battery 2 times increase in output value

Science and Technology, Xiangtan University, as applied to bring the two teams patents, tech Power Battery Co., Ltd. Hunan starfish stranded after the financial crisis in the adjustment of product structure, sales were brisk in 2009, output value increased by 2 times.

Starfish few years ago, the company mainly produces lithium-ion battery miner's lamp, but also produce some lithium-ion battery for electric bicycles and motorcycles. With the advent of the financial crisis, mining industry, exports, power battery products for export are blocked, the output value in 2008 only 600 million, the situation is very grim.

Engaged in the study of lithium-ion battery, Xiangtan University, Professor Wang Xianyou leading technology teams for the company made after the pulse, the development of new energy vehicles the biggest bottleneck is the battery, the company has a good lithium-ion battery production base, there should be targeting the two most battery market prospects for development, to meet various types of electric vehicle battery power needs.

Lithium-ion battery development for existing safety, cost and cycle life of such bottlenecks, technology teams to have two patents used in the production, and made a number of production technology innovation, the costs fell Three into, extended the half cycle life, safety, and further improved, enterprises gradually out of the woods. 20Ah now successfully developed 4 kinds of specifications of the high-power lithium-ion battery, sales gratifying. Development of new electric vehicles 30Ah lithium-ion battery is the first successful development of the province, large lithium-ion battery, a number of manufacturers was well after the trial. Starfish company 18 million yuan output value in 2009 for the construction of the best year since the benefits.

Focuses on helping the future. Teams under the guidance of science and technology, the company applied for a starfish patents and the joint commitment with the Xiangtan University, the "Hunan lithium-ion battery production and research industrialization demonstration base" of the building.

Wolong Electric prices lead to lower than expected sales battery

Results slightly below expectations. In 2009, the company achieved operating income of 2.23 billion yuan, an increase of 4.46%, net profit attributable to parent company 197 million, EPS 0.7 million, an increase of 52.72%, below our expectations of 0.75 yuan.

Prices led to lower than expected sales battery. We believe that the reasons for the order cycle in 2009, lead-acid battery prices from high to low, in the second half of the battery unit shipments of 15% -20% price decline, as sales rose only 3% of the battery of the main reasons. Meanwhile, orders for delayed delivery of the end of the battery are also part of the revenue recognition had some negative impact. We expect revenue growth in 2010, the battery will be accompanied by new production capacity to achieve about 35%.

Rate of decline in cost of revenue growth led to rapid growth. In 2009, the motor business by the price decline in overseas demand and the impact appears negative growth of 11%, while the proportion of traction transformer led to increased transportation costs increase, the rate of management fees and marketing expenses were increased by 1.1% and 1.4%. We expect the next 2 years, the impact of resumed growth in income, expense ratio will decrease.

2010 motor business will quickly recover. Dual role of prices and the recovery of overseas business will be under the rapid recovery of motor, the motor business, we expect the growth rate will reach 40% year on year. At the same time, we will see the company vehicle for ABS motor new business will be the highlight.

In 2010, consolidated gross profit margin levels will remain at 20% or more. Despite the rising costs will lead to the transformer and battery respectively, gross margin of about 4% -5% decline, but the profitability of both businesses are still far better than conventional motor business, which through the product structure adjustment, the company maintained 20 % of the consolidated gross profit margin levels.

Additional projects proposed to form a new growth point. Company intends to not more than 8,000 additional shares, transformers, energy efficient small motors and large capacity lithium-ion battery project, the new project will constitute a new growth point.

Lower profit forecasts and investment ratings. We slightly reduced the company's performance forecast EPS is expected to 10,11,12 years were 0.93 yuan, 1.17 yuan and 1.45 yuan. Given the company's share price has reached our target price of 25 yuan, we downgrade from buy to overweight.

Flat solar cells, watching the market mood quotes

4th Quarter of 2009 by the climate, and the module does not offer such that the arrival in 2010 and gradually decline, but the trend did not follow the lead of solar cells offer down, the battery was flat overall trend is taking the offer, mainly the battery factory orders ample capacity remains high, solar energy industry, said 1 to 2 months in addition to whether the repeated observation of market orders (Doublebooking) the circumstances, but also affect the battery of the key trends offer.

Solar industry said that the 4th quarter of 2009 by the climate in Europe, solar modules offer not so the arrival of 2010 that the first decline gradually, mainly module industry in response to market demand conditions and clearing inventory, partly as a trader clear and cut prices to sell inventory, but the price movements of non-comprehensive, in early 2010 the trend was estimated by adjusting the original price.

However, although the price of the module down, but prices are a lot of solar cells unaffected. Solar cell factory industry, said demand and capacity utilization affected by climate is limited, so large single-part response to market changes and customer demands while the cost of retrench slightly adjusted downwards.

However, the small single-part, according to circumstances and considering up the goods to the battery factory capacity utilization is still high upward adjustment of the situation, adjust the rate of about 0.1 U.S. dollars, but the different characteristics of different customer price adjustments between the Rengyi, so the overall price of solar cell market maintained unchanged.

Depending on whether the market in early 2010 still need to determine the case of repeated orders to adjust prices once the case of repeat orders more serious than originally forecast, estimate the price of solar cells will be adjusted downwards, but if the demand and the original pre- optimistic assessment of the case, forecast flat panel prices continue to remain high probability.

2009 Asian financial crisis makes low-priced products into solar PV market mainstream, leading European and American industry because the production costs competitive advantage is less than the Asian plant, making the order divergent flow to Asia, among which the solar cell is most obvious, Taiwan-based solar cell industry production capacity gradually to reach full load in Q3, China is the dominant industry is seen as the module price.

Although the early 2010 price of solar cells can maintain stable trend, but most of the battery industry that 2010 will continue to show the overall downward trend in battery price, mainly due to lower production costs, then, is the new capacity addition will come out also, supply competition will will continue to increase, especially in the first half of the mainland market in 2010 about 20 gigawatts of capacity expansion, including Suntech, Yingli, Tianwei and other orders were dished out, but the mainland, the small battery factory production to the total expansion of about 10 billion watts, The Taiwan-based battery company, including Motech, E-TON, Yu Jing, a new daylight, subjects such as Sun Microsystems in 2010, there are more than 20 gigawatts of capacity expansion plan.

We should dare to the forefront of the industry among the world visit to the UK Group Chairman Miao Lian-sheng Lee

2011-06-06T20:09:00.001-07:00

We should dare to the forefront of the industry among the world visit to the UK Group Chairman Miao Lian-sheng Lee

"To dare to do business among the world forefront of the industry to do product will do without me there, I have excellent, gifted people I all." November 17, this newspaper Commentator article, "breaking the shackles of inertia of thinking, Open the new world of the Industrial Structure Adjustment "was published, led to seedlings with Yingli, chairman of Health in China.

November 20, he talked about with their actual construction of the modern industrial system and the understanding of structural adjustment, and how to play the role of business in which, and revealed a new target group restructuring in 2012 --- one among the global PV industry class brand.

Hero to be a benefit: product replacement fast, six months after the general availability of high-performance batteries

Author: how do you understand the "benefits Heroes" concept? Increased competition in the photovoltaic industry to play the situation under Yingli Zhang "brand" is what?

Miao Lian-sheng: "products on the market competition, based on Hero's benefit." My words touched the most. To do business, for profit, if the realm of scholarship with a triple, then there are triple-state enterprises to make money. State relied on a heavy dummies, selling of resources, double realm is for others to do the wedding dress, others we eat meat soup, the highest level is that of the people I have, I have excellent money. Benefit from the British to see the development process in recent years, we are working towards the highest level.

In order to achieve this highest level as soon as possible, we will soon have to come up with the latest products.

Earlier this year, the Group and the National Energy Research Center of the Netherlands, Germany, Tempress companies to equipment manufacturers is to develop and implement an N-type high-efficiency solar cells, "Panda program," improve stability of the cell conversion efficiency to 18%. September has completed the construction of pilot production line in June next year, all production lines will be completed before the transformation, the introduction of new products.

I: The implementation of the scheme on the British interest mean?

Lian-Sheng Miao: Yingli usher in a new era for product upgrades. We hope that the Group of high cell conversion efficiency of monocrystalline silicon can be increased by one percentage point per year to 20% by 2012, silicon cell efficiency from 16.5% to 18% in 2012.

For every 1% increase in battery efficiency, photovoltaic system installation costs will be reduced 5%, which will undoubtedly benefit greatly enhance the market competitiveness of the British. As stated in the article Commentator "by improving product technology content and brand, in terms of cost, functionality, price formation on the comparative advantage in order to maximize profit margins."

Author: Yingli so fast introduction of new products need to support what? Is based on what considerations?

Lian-Sheng Miao: technical support, the British domestic and foreign interest in addition to high-end technology with the team, but also within the group established a "great technical team" system for each employee the opportunity for technical innovation.

We have been seeking simple, effective technology transfer route in the shortest possible time to bring the latest technology into products to market. The "technology licensing" to "product brand" will always stand on high-end industrial technology.

The pursuit of "technology is king": the game rule-making and provide national standards for polysilicon production

I: Now Yingli PV industry where domestic and international situation is grim, some say excess domestic production capacity of polysilicon, and recently Yingli sixty-nine Silicon trial production, which is how your understanding and consideration?

Lian-Sheng Miao: any time there are not always the state of the market situation is excellent. Competition, the market turbulence, and can be "one who has mastered advanced technologies, competition in the market who have the right to speak to, control over, the initiative" is the same.

Sixty-nine silicon industry is based on advanced technology, our products will greatly reduce the cost and power consumption, higher product quality, which is the company to constantly adjust product structure, accurately determine the direction of a move of industrial upgrading.

In addition, recently the Ministry of Information Industry and other relevant departments related meetings held in the Inner Mongolia Autonomous Region, the meeting concluded that current domestic production of polysilicon, and can not meet the actual needs of the photovoltaic industry, the so-called excess capacity refers to the backward production capacity.

I: Does this mean the state should limit the capacity of backward? Yingli which will play what role?

Lian-Sheng Miao: backward is necessary for industrial development, which requires as soon as possible the relevant industrial policies and national standards. These days, we should be asked relevant ministries, have sixty-nine Silicon polysilicon production costs, process, technology and other relevant data were reported.

In a few days, the Ministry of Industry and other ministries will go to sixty-nine three silicon industry research, is to national standards and industry guidance polysilicon introduction of the policy for final preparations. Sixty-nine Silicon polysilicon production is expected to provide national standards.

In the "technology is king" era, as if we can be like Haier, "through the continuous improvement of scientific and technological innovation, the industry technical standards setters, and do the enterprise above the industry standard and national standards," then the competition in the market in, you can be invincible.

Call of innovation environment: enterprise line with the world advanced level, government support to move really, the real trick

I: A Review of Yingli development path over the years, you think that structural adjustment as the main enterprises in the modern industrial system, Build target needs attention?

Miao Lian-sheng: I want to tell you that restructuring is not a mystery. Enterprises like vegetables, if you just kind of cabbage, not to sell some money, enterprises must use our brains, kind of fine food, seed-season vegetables. So as to have high value-added products in order to achieve profitable growth.

At the same time, you should always pay attention to the world the latest developments in the industry, can not just be satisfied with is the boss in the country, but also in the "R & D, manufacturing (production), management" in all aspects, with the same advanced level of standards before a full line.

Companies in emerging industries do not Tandaqiuquan, to technology, management, operation on the slow accumulation of experience. This requires the Hebei entrepreneurs have enough patience, a little less complaining and a little more persistence.

I: What do you think the innovation process, companies most need the government to do?

Lian-Sheng Miao: enterprise development certainly can not do without government support, one is in the land, tax, approval to provide convenient and efficient service, on the other, innovative entrepreneurs mobilize the initiative and creativity. Corporate profitability, the risks may be reluctant to engage in technological innovation, investment and a lot of money do not want to engage in technological upgrading, companies lose money when there is no capital may engage in technological innovation, this time to require the Government to take effective measure.

In addition, I would like to be reminded that the Government can consider doing in the performance evaluation part of the article, can foster new, forward-looking industry, how many to go into the evaluation system. Now the Government's efforts to eliminate backward into the examination, as the province of the "double thirty," the assessment methods, and is a good practice.

U.S. scientists have invented a new "paper battery", 10 times the efficiency of lithium batteries

Someday, lightweight battery with an ordinary paper production, is being slowly disappear to print e-mail, e-books and online news reading devices to send and power.

Stanford University in California, scientists have said in the report, they have been successfully coated with a layer of silver nano-materials, carbon paper, into a "paper battery" light is expected to become a new and efficient method of storage. Help coating attached to the same features make it a piece of paper attached to the single-walled carbon nanotubes and silver nanowire film. Preliminary studies have found that the use made of silicon nanowire battery efficiency is now used to power devices such as notebook computer lithium-ion batteries 10 times.

Scientists published in the "U.S. National Academy of Sciences" on a paper said: "The use of sophisticated papermaking technology, through the paper with conductive as the collector and the electrode can be made into low-cost, lightweight and efficient electrical storage devices. "

People can use this battery for hybrid electronic devices, or energy. Using this battery, electronic devices will become lighter, lasts longer, and may one day produce paper and electronic products. Weight and battery life is the power cars and trucks in the commercial development of a major obstacle encountered.

Materials Science and Engineering, Stanford University associate professor and co-authors of this paper Cui Yi (Yi Cui), said: "Our society really needs a low-cost, high-energy storage devices such as batteries and super capacitors simple." Yi Cui that, in addition to portable electronic devices and wearable electronic devices can use it outside, "Our paper can also be applied to all super-capacitors require instantaneous power energy equipment. Because of our paper, the cost of batteries and super capacitors is very low, they also applies to the energy reserves of the grid. "University of California, Berkeley, chemistry professor Yang Peidong (Peidong Yang) said the technology will be commercialized in the near future.

Days of storage batteries into the South African market can

Recently, the South African solar manufacturers to days to study group, and live day to purchase solar energy storage battery group.

South Africa is the largest producer of electricity, before power has been adequate, cheap electricity, but the last two years, frequent nationwide electricity shortage. National saving as an important measure, the South African government in May last year the country began actively promoting solar energy, issued a series of preferential policies, vigorously popularize solar power, solar energy and solar lights and other traffic lights.

The South African companies to come to China, aims to select high quality solar energy storage batteries. Related businesses in the domestic field trips several times after the final selection of days to the South African company Group. Storage battery manufacturers in South Africa ordered the first batch of products will use solar power system in South Africa, the future South African National solar, wind and lighting systems engineering in the gel used in storage batteries are directed to the Group from the days of purchase, while days to the South African Group provide comprehensive technical support and after-sales service.

Lead prices rose less kinetic energy

2011-05-25T00:26:00.001-07:00

Lead prices rose less kinetic energy

Most base metal prices last week, finishing exhibit oscillatory trends, macro-economic recovery remains steady a boost to the confidence of the metal bull, but the spot weak consumption and rising inventories continue to increase the price of repression. October U.S. retail sales increased by 1.4%, higher than market expectations, industrial production grew by 0.1% to achieve a positive growth for three consecutive months. As the global economic recovery was strong last week, the OECD (OECD) is expected to grow its economy in 2010 1.9%, much higher than expected 0.7% in June. However, the U.S. housing starts unexpectedly fell in October by 10.6%, indicating that the economy is still a distance away from full recovery. In addition, the dollar index last week, encountered in 75 first-line support, beginning to show signs of stabilizing, metal prices which will adversely affect the short-term trend.

Lead: LME lead prices last week, oscillation up, to close at $ 2,350 / ton, weekly gain $ 74.5 / ton. Lead prices rose since the beginning of 150%, rising costs make the battery business is deteriorating living environment, in particular, electric bicycle battery, due to too much competition, rising costs can not effectively passed to the end consumer, capital returns are very difficult, forcing many manufacturers substantial discount on the sale of helplessness, the battery manufacturer's operating rate began to decrease, so the late growth of domestic lead consumption will slow down. From the supply point of view, although lead poisoning caused by environmental finishing off some of backward production capacity, but this year they started the construction of about 116 million tons / year of lead smelting capacity is expected to put into operation in 2010-2011, the supply will lead next year greater growth. Spot, due to weather storm lead to the main producing area, making traffic congestion delayed arrival of the downstream procurement lead ingots, which the spot price is relatively strong. In addition, LME lead stocks continued to climb last week, now stands at 135,125 tons, but fell to 275 tons of canceled warrants, in general, due to falling domestic demand for lead-acid batteries, lead by the stock price will rise and the increased supply of late pressure, late upside momentum will gradually diminish.

Tin: LME tin price Xianyanghouyi last week, to close at 15,000 U.S. dollars / ton, weekly gain of 230 U.S. dollars / ton. Overall domestic consumption of tin is relatively stable, but the consumption of foreign tin beginning to show improvement, large domestic enterprises of overseas orders of tin gradually picked up, tin products, inventory turns, the United States tend to rise, indicating to the inventory of finished goods ongoing . With the stock to the end consumer rebound will face a strong replenishment needs. From the supply point of view, the current dry season in Indonesia over the rainy season, the late supply of tin will be adversely affected. Turnover of the domestic spot market is still very active in tin, tin price in the 115500-117000 yuan / ton within a narrow range order. In addition, there is still a small increase last week, LME stocks, is currently 26,940 tons, but canceled warrants also rose slightly to 265 tons, LME spot price of tin in March from last Friday's premium also rose to 50 U.S. dollars 30 U.S. dollars, is expected to short-term oscillations in tin prices will continue to show the trend.

Nickel: LME nickel prices rose slightly last week, to close at $ 16,735 / ton, weekly gain of 455 U.S. dollars / ton. Lower consumption of nickel stainless steel market is still in the doldrums, the basic does not show signs of recovery, since this is October the main reason for the weak performance of the nickel price. This year a large amount of China's nickel imports, many of which are speculative hoarding up, because no hope of recovery in nickel prices during the year, Wenzhou investors may hold part of the end of the release of nickel inventories, expected up to 5 tons. China's abundant supply has prompted trading companies to cancel orders for next year's imports, including a large trading company imported 3,000 tons of the fourth quarter has been canceled, forcing its overseas suppliers will be transferred Nickel LME warehouse. LME warehouse stocks of nickel up to 132,828 tons, the highest level since the beginning of 1995, from November 1994 created by the record high of 151,254 tons, is only 2 million tons less. Another new project into production will gradually increase the supply of nickel, it was reported Mirabela Nickel-owned nickel mine in Brazil SantaRita has now produced its first nickel concentrate, and the next three months will increase production of its 2010 nickel concentrate output can reach 26,000 tons of production capacity target. Canadian resource companies will also consider the introduction of joint venture partners, to build Fenix nickel project in Guatemala, is expected to commence next year. Overall, due to weak demand, increased supply sufficient stock to make the nickel price continued to decline.

Ultimate solar cell (3): full use of a wide range of wavelengths of light

To be able to handle a wide range of wavelengths and multi-junction thin-film phase composition, the industry has begun to be used as electrodes for the development of transparent conductive film can handle a wide range of wavelengths of the material. The main advantage of the existing thin film solar cells visible light (400 ~ 700nm), but in order to improve efficiency, while also using infrared light region. At this time, if the use of existing ITO (Indium Tin Oxide, ITO), light transmittance infrared region will be reduced, and to improve the transmission rate, resistance will rise. Therefore, the need to develop in the 2000nm long wavelength side also has a high transmittance and low resistance of the new transparent conductive film.

As a wide range of wavelengths with high transmission rates, low resistance materials, and is optimistic about the Fuji Electric Holdings began developing graphene (Graphene). Characterized by the migration rate of 10,000 5000cm2/Vs, than the ITO of 20 ~ 50cm2/Vs high three digits. Thus, even if the surface resistance is set to the same with the ITO 10Ω/sq, can also be formed on a wide range of wavelengths with a high transmittance of the film.

Fuji Electric Holdings to form a coating method using graphene film. Graphite coated with material from the low-cost manufacturing. Will be made of layered graphite oxide and graphite oxide after the formation of methanol in the graphene strip. And, by extracting only a single layer coating liquid graphene oxide, and restore to 1000 °C, can form a fine overlapping graphene graphene film.

To control the light through the photonic crystal

In the light control of solar cells, photonic crystals experts also gave a great concern. Noda, Kyoto University research team into the photonic crystals by a variety of methods on the application in solar cells was studied. For example, wild Tianjie Shao, using three-dimensional photonic crystal, "Preparation of solar cells by carrier recombination can not exist when the light generated by the crystal, can prevent the carrier recombination."

Three-dimensional structure formed before the method is more complicated and can Noda developed a simple method of forming the structure. The method used in the thickness direction on the opening hole aluminum ramp mask, etching of silicon. Because the mask can be tilted to form an ion along the track, and therefore can be inclined holes on the silicon etching. Mask rotated by 180 degrees and then etching, was well able to form a stripe-shaped accumulation of three-dimensional photonic crystal structure. Has been successfully processed to 0.8µm pitch out of the deepest reaches of the diamond structure of silicon to 2.2 cycles of stripes structure. The research team said that if we can shorten the interval to 2 / 3, will prevent the solar cells in the carrier recombination.

Battery Charge Management: Flexibility is the key for

Battery Charge Management: Flexibility is the key for

And past use of portable electronic products as disposable batteries or alkaline batteries of different power, today, whether laptop, cell phone or MP3/MP4 player, all the basic use of lithium ion, nickel cadmium or nickel-hydrogen rechargeable batteries, not only reduce the use of cost-benefit environmental protection, more importantly, a larger battery capacity can be done to get a longer battery life. Rechargeable batteries because of their characteristics are also made to the system developers, the new requirements, in order to make rechargeable batteries have a longer life, the correct charge circuit design and component selection is critical, whether it is an external charger or the system internal rechargeable power management solutions are required depending on the use of careful consideration.

Single-chip charge management solution, or will become a mainstream

In portable products, battery charge can usually be two ways, one is to use the system itself, plus a host MCU PWM demodulation unit (PWM) to achieve, and the other is the use of highly integrated single chip charge management IC . "Single-chip charge management IC's greatest strength is to have a higher reliability, while the MCU + PWM solution is simple and cheaper." Marketing manager for Fujitsu Microelectronics Wang Yun in an interview with reporter explained, "Manufacturing Systems providers can cost, reliability and so the pros and cons comparing the two programs, you can choose the most appropriate option. In the long run, single-chip charge management IC with the declining cost and increased functionality and external communications, and more of the applications more reliable selection of a single chip will become a trend. "

According to Wang Yun introduced Fujitsu's charge management products are mainly located in the 2Cell of the market, and 2 ~ 4Cell applications have to be the biggest market of them notebook computers. From 15 years ago, Fujitsu R & D team to power management of laptop computers and Fujitsu R & D department, has begun the development of the charge management for laptops IC. Through several generations of continuous development and improvement of products, new research and development of lithium battery charge management ICMB39A132 and MB39A134 in Taiwan and mainland China has been applied to many manufacturers, but also by the recent high-profile attention to the netbook market. "In notebook applications, which, due to charge the battery a few years ago after another explosion occurred, so that the design of the notebook manufacturers increasingly take charge part of the design, management section in charge will be selected on the stability and reliability of high quality big brand power management IC. "he said.

However, BCD Semiconductor Corporation from AC / DC Product Director Dr. Wu Xin MCU + PWM is more optimistic about the program, he considered that the formation of special charge management IC circuit control scheme is simple, but relatively simple function, usually only on the specific parameters of the lithium-ion battery charging, and different models of portable products often use different model specifications of the lithium-ion batteries, if using a dedicated chip, the development will result in duplication and waste of resources.

"Implemented by MCU + PWM Buck circuit and control method of low cost flexible and can easily be improved and upgraded, can be applied to a variety of lithium-ion battery." Wu Hsin said.

BCD Semiconductor is an analog signal integrated circuits in the Greater China manufacturers (IDM), in power management IC product design development and manufacturing. Unlike the rest of the market Fabless design companies, BCD has a 6-inch semiconductor wafer fab

(Including Bipolar, CMOS, BiCMOS, and BCDMOS and other production processes), can product design and advanced technology to optimize product performance and cost, to provide a cost-effective system solution.

In fact BCD Semiconductor's focus is on high efficiency and low cost AC / DC off-line power adapter / charger controller chip, the company developed in 2006, the first generation of the primary side controller AP370x series is the first launch of its kind on the market products. According to reports, AP370x using the primary control and output cable compensation proprietary technology, built-in temperature compensation and transformer primary inductance compensation, you can save optocoupler and secondary case of feedback control circuit to achieve high accuracy output voltage and current control , thereby greatly reducing the number of power circuit components, simplifying the circuit design has been successfully used in mobile phones, wireless, cordless phones and wireless routers and other products charger / adapter. "To further improve the power conversion efficiency, lower standby power consumption, we further introduced the industry's leading five-star standard to meet the second generation of the primary side controller AP376x series, the following no-load power consumption 30mW can easily meet, including energy Star EPSv2.0 and five-star standard mobile phone charger all the world, including the charger / adapter, energy efficiency and load specifications. "Wu Hsin said.

Increasing diversity of input power

With the growing diversity of people's living environment can be used for battery charging power supply is also becoming more diverse, in addition to the traditional 220VAC adapter, the user also want at any time through USB port or car power source for various devices such as battery charging, user requirements in addition to charging the device can continue to use its features while, so charging management circuit devices need to be more flexible to accommodate a wider range of applications.

Obviously, the new requirements to the system manufacturers greater challenge. "The challenge comes from the first charge management IC requires a wider operating voltage range, thus requiring the use of higher voltages for semiconductor chip design process." Wang Yun said, "The second challenge is to ask the IC to the different input power to make corresponding adjustments, as well as battery charging and system power management can make some. "Fujitsu MB39A132/134 his charge management IC as an example explained by the distribution of the dynamic input current to ensure that the system power and battery charging can be stable.

The AC adapter / USB / Car power provided by the voltage and current are not the same, while the rechargeable battery voltage and number are not the same, when the charging voltage is higher than the supply voltage to be carried out through the step-up charge, such movements charge management IC pressure not seen in the market. Besides working at the same time charging the device, requiring charge management IC have a good anti-jamming design, keeping in mind the case of low battery voltage, charge current is greater than the discharge current to ensure that, to avoid "living beyond their means" to happen. "Charging IC design from the point of view, the current challenges include: 1, how to further improve efficiency and reduce the standby charge power; 2, how to effectively manage multi-channel power supply and the load; 3, and also how to improve the charging rate to ensure the safety of battery life; 4, how to further expand the flexible charging control configuration to meet the requirements of different types of battery charge. "Xin Wu added.

He believes that portable devices such as cell phone chargers charger is a relatively mature and stable market, domestic producers are mostly corresponding to the main manufacturing, technology development, the power is relatively weak. And the charger itself is commodity nowadays, manufacturers relatively great pressure on cost control, acceptance of new technologies is relatively low. In recent years due to public awareness of environmental protection, government and various environmental organizations, agencies, including phone makers themselves, have raised a number of energy-saving environmental standards related to the charger, for example, the Ministry of Industry of China promulgated the "Mobile Communications Handset charging and interface requirements and test methods "(YD/T1591-2006), Energy Star EPS2.0, mobile phone charger grading standards, etc., are designed to reduce resource waste, improve energy efficiency and reduce the load Konghao. The introduction of these standards charger products largely driven by technological innovation.

"Chinese manufacturers are the major difficulties faced by designers of the technical practice of not charging, charging failure to fully grasp the design requirements." Wang Yun said, "while the function of each charge management IC is different, the user of the new lack of understanding of product design was not approachable. The solution mainly depends on charge management IC manufacturers to increase market products and technologies, to provide multi-faceted designer technical support, so that designers can quickly grasp the design of Charge Management technology. "

Notebook designs, engineers charge management IC design very seriously, otherwise the problem will cost the event a lot of time and energy engineers, so early detection of problems in research and development is critical. Wang Yun said that in addition to providing evaluation board for Fujitsu's customers system evaluation, but also developed a laptop power supply design evaluation system, through the system, as long as the customer can provide a complete circuit of any problems that may occur prior to full inspection R & D to help reduce the risk.

Occurred late last year for the global financial tsunami hit big consumer electronics products, "but we are delighted to find that consumer electronics has started to recover before the overall economy. In particular, benefited from state subsidies home appliances, notebook computers and LCD TVs rapid warming and other markets. "Wang Yun said. "Next year we will continue to increase in the power management IC R & D investment, will be the latest version of the charge management products. In recent years the development of new energy technologies, high-profile battery technology, lithium / lithium-iron batteries will also be will be applied to more products were. from the power management IC point of view, more secure, more accurate, multiple protection features, external communications, cell balancing function and multiple charge and discharge the battery will be a wide-input voltage battery charger and so on The future development trend of management. "

Integrated programmable logic devices using high-power management

Energy-saving design the most serious challenge is to use the microprocessor to manage the power supply. Microprocessors are not optimized for power management, they must deal with too many instructions, and the reaction time is slow, may lead to thermal breakdown, and even sudden catastrophic failure of circuit boards and systems. Although the use of microprocessors in power management has been the traditional approach, but using the power management logic devices faster and more reliable.

Lattice Semiconductor introduced in April 2009 PowerManagerII series of new products, including POWR1220AT8 for power monitoring, repair and voltage measurements provide an excellent solution for programmable devices that can replace the reset generator, control IC, Watchdog Timer control, sequencing / tracking and hot swap circuits, and other IC, to provide users with the necessary tools and functionality to meet the large-scale base stations, high-end servers and small single-board computer systems such as the green standard of energy saving. Depending on the design, energy savings vary, but save 30% are not uncommon.

Reduce power consumption and energy conservation is an important way to turn off the unused portion of the circuit board and IC load is low, reducing the power consumed. PowerManagerII highly integrated programmable voltage monitor IC to integrate the device into a device which helps reduce system cost and improve reliability. For example, PowerManagerII1220AT8 monitoring power up to 12 circuit boards, providing up to 20 open-drain (open-drain) digital outputs and 8 DC-DCtrim/margin output. 48 on-chip macrocell CPLD and four programmable timer, the device generates a CPU reset signal, including pulse trailing and power failures interrupted. 20 There are four output can be configured for high-voltage MOSFET drivers. There are six general-purpose digital inputs can be used for other control functions.

One advantage of this design is that they can be sensitive to any platform using the power as standard power management solutions. Platforms and product lines in the entire establishment of such a standard solution obtained by the efficiency of the obvious, from the design time and the required number of devices can be manifested. Energy-saving devices for low power consumption and the demand for greatly increased over the past few years, and this trend will continue, it is expected that integrated programmable power management devices will be more widely used.

Lattice plans to the next generation of power management devices to improve integration and includes more features, not only can support power management, but also realize the management of the circuit board itself. Its function will be expanded to include temperature monitoring, fan control, NV error log, the user logic and system interfaces. In addition to power management products, the company also offers a series of low power programmable logic devices, including ultra low-power CPLD and LatticeECP3FPGA ispMACH4000KZE series, which is only about the cost and power consumption with the other half of FPGA SERDES functions.

Li-ion battery electric vehicles practical concern of economic

With the increasingly hybrid and electric vehicles closer to production, the concern of the lithium-ion batteries have begun to shift from the economic practicality of security. At the recent meeting of plug-in cars at a panel discussion, several speakers said that once the battery to achieve this advanced mass production, significant cost reduction is possible.

Members of this advanced battery safety has not expressed concern over the battery in the consumer electronics products have appeared on the phenomenon of overheating and fire.

Johnson Controls-Saft Advanced Battery Systems is responsible for hybrid battery system of government affairs and external relations director Michael Andrew, said the company's goal is to lithium-ion battery pack cost reduction by 50%.

He said, JCI-Saft batteries are installed not only to consider the cost of materials, but also consider the battery production. He said that the battery manufacturers can learn how to other industries more efficient lithium-ion battery production experience.

Andrew said, "We now have an opportunity to revolutionize the production of these batteries." "We think we can learn from other industries in the process technology used to quickly reduce costs."

Evenly matched with gasoline

He said, JCI's goal is to create a hybrid or electric vehicles for the use of the battery pack, allows consumers to spend and spend three years of the same gasoline engine.

Nissan North America manufacturing engineering and vehicle production and engineering department, said Mark Swenson, vice president of Nissan in 2012 reduced the cost of type Leaf plans electric vehicle involved in manufacturing battery and battery in the vehicle manufacturing plant will be assembled into battery packs.

A123 Systems Inc.'s Vice president of business development, said Ric Fulop, he believes, as the industry matures, the cost of the battery pack can be reduced by 9% per year. More battery power to make some cost savings, but can also optimize the production process and use high quality materials to cut other costs.

More power

Dow Chemical Co. Global director of business development, said Ravi Ramanathan, battery costs can also make a stronger and more efficient electric batteries, as well as quality control during production to be cut.

Carmakers do not talk about hybrid and electric vehicle battery pack used in the cost. However, some estimated to be Chevrolet Volt lithium-ion batteries used in the cost estimate of about 8,000 U.S. dollars.

Ramanathan said, "the high cost of the battery, you must come down." He said, the initial cost may be high, because the car manufacturers of cars and batteries to over-design to ensure that consumers will not appear on the technical loss of goodwill of mechanical failure.

Pink solar cells capture more sunlight

2011-04-21T20:18:00.001-07:00

Pink solar cells capture more sunlight

Ohio University researchers said, when production on the Earth's environment-friendly solar energy, the pink may be a new "green color." Scientists have developed a new dye-sensitized solar cells (DSSCs). The red dye used in the battery and the white metal oxide powder mixture showing pink, can capture sunlight.

Allegedly, these new pink materials, photoelectric conversion is the best material, although the conversion efficiency is only in commercial applications, half of silicon solar cells, but its cost is only a quarter of silicon solar cells.

Pink is the dye-sensitized solar cells most typical color. Most contain a ruthenium dye, ruthenium red. Mixed with red dye pink metal oxide powder is the most commonly used titanium oxide or zinc oxide, these two metal oxides are white. But researchers at Ohio University created a more innovative materials does have color, they used the metal complex, exploring different particle shapes to enhance the photoelectric conversion efficiency.

This is the first time, researchers using non-single-oxide dye-sensitized solar cell manufacturing. Selected because of zinc stannate is zinc stannate series of complex oxides with tunable properties. This makes the next cut dye-sensitized solar cells possible.

Why dye-sensitized solar cell is pink, not the same as the blue silicon solar cells it? Traditional solar cells showing a blue anti-reflective coating because of the reason. These coatings improve the absorption of green light, green light is the solar energy spectrum, the strongest light. Ohio University researchers have not developed anti-reflective material coating materials.

Color determines the solar cell can capture the wavelength of light, so scientists can modify the color of the special characteristics of solar cell optimization. At present, the development of dye-sensitized solar cells, scientists have used ruthenium red dye to obtain the best results.

If you want to get the best efficiency, you need to take into account access to the voltage and current. Voltage is a potential material to provide energy; current is material to the amount of charge transfer. If you can absorb a very wide range of wavelengths, it will have to sacrifice voltage. If absorbed into the limit of very high energy, high voltage can be obtained, but they have to sacrifice current. Researchers are trying to find a balance.

60 years since the 20th century, since the silicon solar cells have emerged. Since the 20th century, scientists began developing the 90's dye-sensitized solar cells. In dye-sensitized solar cells, dye molecules cover the tiny metal oxide particles, and is stuffed with a thin film. Dye molecules capture light energy and release electrons, and metal oxide particles more like a wire, will be among the electronic transmission to the circuit, but the electronic transfer between the particles may be lost. This is the researchers are designing the merger will be tiny nanowires to transfer electrons directly to the circuit reasons.

They also explore the possibility of using nano-trees - like the shape of nanowires, like tree branches. Which absorb light and transfer the current structure is the best structure? Researchers believe that tree! Leaves provide a large surface area for capturing light, the branches will be transferred to the roots of nutrition. In their dye-sensitized solar cell design, dye particles will provide coverage of the surface area, nano-trees grow between the branches in these leaves, transfer electrons.

Therefore, dye-sensitized solar cells the future growth of a tiny pink will be the "tree", but other colors are also possible. Researchers are studying to work better in the new dyes and dye compounds.

China's solar panels will be restricted by the U.S. tariffs

2011-04-17T20:39:00.001-07:00

China's solar panels will be restricted by the U.S. tariffs

Recently, news that China exports to the U.S. by solar panels will be up to $ 70,000,000 U.S. tariff "special attention."

The United States Tariff Act to be implemented, a time when the United States on the occasion of solar cell industry malaise. The implementation of this bill would likely harm not only to foreign manufacturers of solar panels, and the United States and abroad will also have solar panels have a great impact on dealers. More serious consequence is that this will further aggravate already tense Sino-US trade disputes if.

December 1 last year, the Spanish energy company in the United States branch of GES USA to the U.S. Customs officials sent a letter in the letter asked the company if you want to import solar panels from China, the United States which tariffs will be levied. Unexpectedly, a ripple, the situation has developed to the United States will impose a special tariff level.

January 9 this year, the U.S. Customs department responded to the letter, said the solar panels from China can not perform tax system. Instead, the panels included with the security and energy-related electronic components, will be levied as import generators and 2.5% of the tariff. 2.5% of the tariff is levied on imported products, the implementation of the standard normal tariffs than the United States a product intended to limit the punitive tariffs on imports is much lower. For example, three weeks ago, the Chinese tires safeguard, the United States to the taxation of tire imports from China up to 35% of the tariff.

However, the implementation of the tariff when the global downturn in the international solar cell industry. By the continued expansion of China and the global solar industry solar panels double impact of falling prices, a lot of solar panels produced a steady decline in corporate profits. Due to overcapacity, and now a way to raise prices to compensate for tariff losses caused by the price accepted by consumers is difficult, but since January this year the price of solar panels has gone down 5 times.

According to the U.S. Department of Commerce statistics show that in the first 7 months of this year, the U.S. import and export of solar panels is roughly equal to the total, of which 605 million of imports and exports 555 million.

By the United States and abroad to form the U.S. solar energy companies insist that the Solar Energy Industries Association, the U.S. government to impose special tariffs on solar panels will result in U.S. imports from other countries impose higher tariffs on similar products.

The U.S. Customs Department's decision into the U.S. solar energy industry in the United States importers and manufacturers of solar equipment in two parts. With China accounting for the increasing share of U.S. imports, the tariff will be the United States following the tires, automobiles, and chicken and then a rise to trade tensions between the sticking point.

American Solar Energy Industry Association, Xi Luoen? Royce Chi (Rhone Resch said the solar panels of some Chinese manufacturers are planning to move to the final assembly line in the United States, so one day to avoid the potential risk of additional duties.

The tariff will be widely applicable for the residential, commercial or industrial electronic systems provide power and energy, solar panels, and built-in solar panels, small light bulbs as a lighting device has been imposed tariffs of 3.9%.

U.S. criticism of the legal profession is not the early detection of solar panel industry, the import tariffs. U.S. Customs and International Trade Bar Association, former chairman of Dewey & Leboeuf is also a partner in Washington's Mel Schwechter said: "For an industry, the use of 8 months time to recognize a duty arising from it is some of the serious consequences of substandard routine. "

Once the U.S. Customs department ruled each company due to "false or false" solar panels imported materials which led to early detection is not already on the solar panels should be included in the non-tax provisions, importers are likely to bear over the past 5 years Import tariffs on solar panels to avoid legal liability.

Chi Rice said in court that the association plans to put solar panels on the list are classified in the generator question.
