Dongguan Electrical Battery Overcoming Technical Difficulties
Recently, in the United Kingdom Greater London M25 motorway around the city, a bizarre form of electric vehicle gallop after two laps, have the energy back to the starting point for more than 30 km away. 400 km-long journey, a way not to add energy. This is RadicalSportscars and Imperial College London team of environmental sustainable development in electric car vehicle SRZero.
A battery can be recharged several times, how far can recharge the batteries, electric vehicle battery is the core technology. McNair New Energy Limited (McNair), developed for light electric vehicle battery can be rechargeable 2000 times, can run 360 thousand kilometers, called the industry’s “long life” battery.
McNair plans to spend the next 1-2 years, small-batch production of light low-speed electric vehicles, golf cars and yachts with the power battery.
Battery power for 360,000 km
Recently, the reporter went to the Industrial Park, Dalang Town, the level of McNair. McNair is not the most buzz in the park, but it does power batteries, electric vehicle industry is the most critical aspect of people new light.
Chief Engineer Liu Xiaohong, said McNair, McNair small batch production of the current electric vehicle batteries, to complete a charge to 6 hours. This applies to low-speed, short-range electric vehicle battery light on body weight 1.1 tons, speed 60 km -80 km of electric vehicles can be more than 180 km endurance. Rechargeable up to 2000 times or more times. In other words, a power battery able McNair approached 360,000 kilometers away, to 40,000 km a year, then it can use 9 years. In industry, this indeed a “long life” battery.
R & D, “longevity” of the power battery, McNair set up a professional R & D center. McNair rely on their own post-doctoral research station, there are more than 200 full-time R & D personnel, sprint power battery electric vehicles, including design and development.
Seek to capture “the most fatal flaws”
McNair, general manager of Mao Tiejun very clearly remember, when the test car’s odometer jump to 180 km, the clap cheer themselves and their colleagues at that moment. The results show that the battery completely in the design range, or even, even better than planned.
Mao Tiejun said McNair in 2006, electric car battery research and development, Hong Kong and Guangdong Province in 2007 for the project tenders and get started 8-10Ah battery of structural design, preparation and mass production such as research and development.
“As of 2009, the company and its key materials, battery electric vehicle research and development costs on the accumulated investment of 12 million yuan.” Mao Tiejun said.
To successfully enter the field of electric vehicles, McNair is taking the Chan Xueyan line, with 712 research institutes, Dongguan, Shanghai University, Institute for Nanotechnology in-depth cooperation, namely, security technology R & D electric vehicle batteries, battery with nano-materials, key technologies, work the removal of the domestic battery industry “crown” on their own pearl.
Currently, electric vehicle batteries and the development of key materials, the McNair for invention and utility model patents, over 10, 10, a number of provincial and municipal projects in 2004 in 22 countries and regions registered the “McNair” trademark. This year, McNair started to wade across the industry as “the most fatal flaw” of the cell consistent difference, and this is related to electric cars can really enter the market of mass production.
Introduction of domestic production standards expected
“We hope to achieve power battery mass industrialization, to secure a leading position. The future will be further developed for high-speed electric vehicles, CMB, bus power batteries.” McNair told reporters Vice President Shi Qiao Shi, in battery technology, McNair is currently in the domestic leading position.
A few months ago, McNair has successfully developed electric vehicle batteries experimental samples, the second half of the trial production in small quantities. Qiao said the history of the world, McNair future plans to spend 1 year -2 years, small-batch production of light low-speed electric vehicles, golf cars and yachts with the power battery. Accumulate some experience of road test data, and further into the future of high-speed electric vehicles, CMB, bus power batteries.
This reporter learned that, at present China has not yet introduced the production of electric vehicle battery standard. Therefore, the whole industry, battery production equipment was not standardized. Once the establishment of domestic production equipment standards, while McNair developed battery may have to develop their own production facilities. Mao Tiejun said that the motive power for electric vehicles has not yet scale production and sales, not profit form the production alone, to support related research enterprise becomes relatively weak force.
Mao Tiejun that if the Government can provide to financial support from the policy, you can help enterprises better Chuang technology related.
