Li-ion battery hybrid motor car market prospects

Li-ion battery hybrid motor car market prospects

Japan Automobile Research Institute recently announced that Japan will take the lead in the popularity of hybrid vehicles in the lithium battery, which will enable Japan has led the world in countries in hybrid vehicle technology icing on the cake.

Li-ion battery than the current mainstream nickel metal hydride battery size and weight have reduced by about half, to improve the hybrid's fuel efficiency is important, has become the first choice for the next generation of hybrids. At present, around the production of lithium batteries, the world's car manufacturers and the electrical, electronics companies have developed in an increasingly competitive.

Japan's Hitachi said it would invest 20 billion to 30 billion yen by 2015, the current lithium-ion batteries for hybrid production capacity by about 70 times.

Allegedly, Hitachi will increase investment and expand its business by Tokai, Ibaraki Prefecture is located in capacity, as soon as possible new high-capacity lithium battery production, the product will be mainly provided to the U.S. General Motors Corporation.

Earlier, Germany announced that from 2009 to launch a 360 million euros in the automotive lithium battery development program, almost all German cars, and energy giant, will carry information to join. The German government said the plan, marked Germany will enter the electric car era.

At the same time, Daimler and RWE energy company also announced that it will work together to build 500 electric car charging stations. German auto industry alliance is expected of Germany before 2012, commercial production of electric vehicles will be pulled off.

The main advantage of electric vehicles is both energy saving, but also produce a wide range of environmental effects. Studies have shown that the use of electric vehicles to pass one kilometer road, the cost of needed gasoline cheaper than 80-90%, the amount of carbon dioxide emitted by vehicles is generally 70%.

Recently disclosed METI, Japan, in 2010 and strive for the next generation of the new lithium battery electric vehicles.

May 15 this year, Toyota, Nissan Motor Co. and Matsushita Electric Industrial Co. and other related businesses signed an agreement to jointly develop a unified specification of the new generation of automotive lithium batteries, and plans to mass production within 2 years. Toshiba decided to spend 500 billion yen to develop electric cars with lithium-ion batteries, which power will be two years into the efficient semi-commercial production is planned for 2011 will be increased for high-performance lithium-ion batteries with different characteristics three categories, namely, in addition to the current ordinary type, the respective development support will also be hybrid and electric vehicles high output and high energy density power type lithium ion battery type.

Popularity of electric vehicles is a key issue is the need to build enough power to add facilities. To this end, Tokyo Electric Power Company announced that it will take the lead in the infrastructure, first built in the metropolitan area next year, more than 200 charging stations, three years after the increase will go to more than 1000. Japan's major car companies have responded positively involved in the study and engineering, and eagerly look forward to "de-oil" era came to Japan as soon as possible. At present, the Tokyo Electric Power Company has successfully developed a large-scale rapid charger, every 10 minutes fully charged, can travel the distance is 60 kilometers, so charging time is shortened, and further accelerate the increasing use of electric vehicles in Japan the pace.

It is reported that the establishment of a charge for each facility cost 400 million yen. Tokyo Electric Power Company for supermarket parking lot in Japan, convenience stores and post offices and other public places charging facilities gradually building to facilitate people off shopping and errands can get the car added power.

According to Japan Automobile Research Institute predicted the popularity of hybrids according to the present projections, by 2020, hybrid car in Japan will reach about 360 million. High-performance lithium batteries have been promoted if the popularity of hybrid vehicles reached 7.2 million are likely to further levels.

Local media commented that if the Japanese lithium batteries in a new generation of vehicles to obtain ISO certification opportunities and be in charge, and the enterprises will benefit immensely.

International trade that the electric car market in the next decade to develop into what kind of scale, will depend on whether the cost of lithium batteries down quickly, but an indisputable fact is that the potential of this market will be huge enough to meet the needs of large-scale production.

Application skills of the laptop battery cost analysis method

Application skills of the laptop battery cost analysis method

With the rapid proliferation of notebook computers, notebook batteries by the majority of the growing importance of consumer attention. Give a good laptop battery is not only the user's mobile commerce and digital lives of great convenience, but also can eliminate the future use of insecurity. A piece of notebook batteries do not, can not be met except for the users of its mobile digital life, it will also bring the use of hidden dangers, especially security issues. A battery explosion caused the destruction of a notebook, or even lead to more serious consequences.

So choose a good laptop battery is significant. However, the battery update the original price of the hundreds of thousands, many users choose a better price in the market face replacement products. But the two maintenance market price of the replacement products from 100 - 800 range, making it difficult for consumers to judge the quality from the price of the good or bad.

In this essay, by analyzing the composition and laptop battery designed to help people in from the current market price of laptop battery on businesses and other considerations to choose the best laptop batteries.

Lithium-ion laptop battery is 18650 batteries with protection circuit board and composed of PVC plastic shell, the following analysis of the cost of an item:

1.18650 2200,2400,2600 mah lithium-ion battery is divided into three types, a typical laptop battery assembly with 8 batteries (series 2 and 4). If it is genuine original batteries, usually Japanese and Korean manufacturers or domestic regular grade A 18650 batteries, these batteries have the quality assurance and safety through rigorous testing, the cost is usually in the U.S. according to the different capacity of 3 yuan between left and right one, a normal laptop battery (8) costs about 24 U.S. dollars, equivalent to RMB: 170 or so.

If B grade or disassemble the battery (installed after the quality of the batteries, Japan, South Korea has the quality of the safety issues and even batteries are often dumped in China) the cost price of between RMB 10-15 Such batteries or re-assembly after assembly, an 8 batteries notebook batteries cost 80-120 yuan. In addition, even worse, some unscrupulous manufacturers to 18650 with more poor, often have security problems, it is easy to blast out of your notebook assembly of low-quality products, and its eight batteries in the laptop battery can cost around 50 yuan .

2. Laptop battery on the PCB panel, a good control panel, you can extend laptop battery life to protect the security, the cost is usually about 80 yuan; if it is a bad battery control panel PCB dysfunction, or disassemble board, the cost of 30 yuan,

3. PVC glue on the shell, the cost of a good plastic shell of 30 yuan, the bad low-quality goods at 10 yuan.

Summing up the appeal, there is a good quality assurance by the notebook battery (8) the cost should be around 280, so a good non-Original Notebook Battery (8 batteries) and a lower price, including operations cost and profit to reach the end consumer's hands should be 350-550 yuan; if it is low-quality notebook battery products B (8) costs 120 yuan, the price for 200-300; If the minimum quality laptop battery (8) costs for the 80 or so, the price is usually between 100-200.

The Canon Digital Rebel XT in the great success of the original Digital Rebel, build a device that has literally transformed the world of digital cameras on the head when introduced. A six megapixel SLR that sold with a goal of less than $ 1,000, the Digital Rebel not only Nikon, Olympus and Fuji in the D-SLR business question, but has pledged to reduce drastically in the all-in " prosumer "market. After the names of its highly popular "Rebel" line of SLR cameras, entry level, the Digital Rebel offers many new features and enhancements to the 10D same exposure, but something to keep costs under control and ensure some differentiation between the rebels and the scale of his brothers at a higher price.

When the original Digital Rebel has ceased, the Digital Rebel XT now runs and improved. The Rebel XT CMOS sensor 8.2-megapixel (8.0 megapixel images online) for an even higher resolution, better manual control over AF and metering modes, an adjustable EV step size, flash exposure compensation, and has a custom menu function to adjust the unit. There is a vast improvement over its predecessor, although the original Digital Rebel excellent camera in its own right. Read on for more details!

 

As digital cameras are smaller, less space for buttons, controls, indicators, and - the handles. One of the most controversial aspects of the EOS Rebel XT / 350D is the size of the handle. And yet, the size of the grip in relation to what we are accustomed. Photographers use a Canon bodies Series 1 are the Canon EOS Rebel XT / 350D is very low grip. P & S enthusiast photography the handle is similar to what is used - although the objective of greater diameter may leave less space than a few fingers avid P & S digital cameras. users of Pocket P & S is the handle is too large. You can not get their fingers deep into the handle that large organizations with Canon. By simply turning the right hand rear of the camera only gives you a good hand grip size (my opinion). My finger slides easily in a short lower body. Canon has a volume of grip small sacrifice to achieve a compact design - you can not get a grip size of a series in a small camera(camera battery).

I want Canon Canon EOS Rebel XT were added grip / handle is rubber 350D 20D. The 300D Digital Rebel has a rubber grip, but not as sticky as the handle 20D.

A disadvantage of the small handful of difficulties in tracking large vessels, while only handle increases. The purpose of the controls of the organization, not the reverse. The solution to this problem is simply in order to maintain control. Canon BG-E3 Grip (see Annex below) is a better solution, but the small size then sacrificed in part. Attached to the BG-E3, the handle is very nice image size with a good feeling. The horizontal format is better than without the grip BG-E3, but not as nice as the handful of portraits. The BG-E3 can be removed quickly installed / to make the best of both worlds. To manage a vast landscape, choose the 20D or 300D.

The Canon EOS Rebel XT / 350D style is very attractive and good in general / finish and build quality is very good. Of course, it is robust, weatherproof, waterproof Canon 1-series, but there is a difference in the cost so great. And while it might not be as robust as the 20D, I do not want to fall either to a 20D. The slightly rough, matte finish plastic exterior feels cheap / low for some, but the 350D, the Rebel XT is not authorized and has no interest for me to build (plastic technology today is very good). A handful of high quality rubber that go in creating a greater sense of quality.

Buttons and doors have not felt the top of the line quality of a body 1 of the series, but not weak. On the issue is - do not open the door, while the 350D is written to the CF card or lose the photos posted. I consider this function as an error, but usually do not open the door when the unit is written anyway (an indicator light on the back, it is clear when it occurs). I can detect very slight movement of the body by pressing firmly on the handle in just the right place XT. Again, this is not a big problem in my opinion.

The Canon EOS Rebel XT / 350D is almost finished a little brand - in particular marks, where the bayonet is the closest to the handle.
