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.
