Genghui Li as a senior expert in the field of electric vehicles, Vehicle Branch Director of the Chinese Engineering Society, the Institute of Tsinghua University, automotive, auto safety and deputy director of the energy the State Key of Laboratory Professor Chen Quanshi attended almost 20 years, electric cars in China by the research subjects to the point of a great concern for the whole company is now a hot market of laboratory,Hp laptop battery R & D to start the process.
Chen Shi-Quan has been a strong supporter of the development of electric vehicles. 20 years ago, he proposed to the State to develop electric cars, "Eighth Five-Year" period has begun in the development of electric vehicle technology.
But the face of this boom in electric vehicles Chen Quanshi in comfort, but also maintained a clear and sober scholars accustomed. In his view, the technology of electric vehicles in China is not mature, but not achieve the industrialization of Qiu Yao, particularly in engineering research results to inform Huan need the state to spend, and businesses high Qian Mu electric car is Reqing, many speculative elements.
The Economic Observer: Not long ago, the State issued a "buy on the launch of new energy vehicles to subsidize" private pilot rating for the first time defined the purchase of vehicles with new energy efforts of private grants, HP HSTNN-DB02 Battery, HP HSTNN-UB02 Battery, HP DP390A Battery, how do you think of this policy? Grant efforts enough?
Chen Shi-Quan: The subsidy can be seen from the state for the development of new energy vehicles to focus on pure electric vehicles.(HP DP390A Battery, ) Were classified as standard models of hybrid power, the maximum subsidy of 3,000 Yuan. This is the first hybrid in the policy framework of the "energy" model, rather than new energy vehicles. The increase in initial stop only weak hybrid device, the intensity of this grant is sufficient. But the hybrid force, due to an additional set of power system, to 3,000 yuan subsidy is clearly not enough. But it is also indicative of the attitude of government authorities, the strength of Japanese companies like Toyota hybrids, Honda has done an excellent job, very difficult to catch up with domestic firms. pure electric cars we all just started, and to encourage policies to focus on the pure electric and plug-in hybrid aspects. Subsidies for private purchase after the introduction of the government must do at this stage, the basic policy in place to encourage consumption, and the rest depends primarily on the business performance.
The Economic Observer: Since the policy was primarily established to promote our technology is not ready? Today, companies of electric vehicle technology and products, ability to meet the demands of industrialization?
Chen Shi-Quan: technological bottleneck electric car battery technology is mainly the current density of the vehicle's battery power is relatively low, the need to improve mileage out of battery assembly. Also the stability of the battery life is also necessary to improve further, Chany Dan Ju Bu Neng electrical issues are resolved a Dianchi Deng but through demonstration operations Zhujian through practical application to discover and resolve problems and improve battery performance. There is a demand driven market, the battery industry will accelerate the pace of technological progress.
Another difficulty in industrial scale is the lack of production line of battery power, but some companies have begun to invest, (HP HSTNN-UB02 Battery,)but not in the size of the production line of internal battery power. Battery electric vehicles are now assembled produced by the first mobile phone, laptop battery companies beat by hand.
In addition, while many domestic firms have introduced electric cars, electric cars, but cars Zaochu Several laboratory and large scale industrial production of these two concepts. Scientific research for mass production lines have a long distance requires a lot of research and development. This country is still very low, and the government's need to increase investment in this part.
