The development of new energy vehicles in China faces three major problems

the research and development of new energy vehicles has become inevitable in the reconstruction of the automotive industry pattern in the world today. There is a big gap between China's traditional energy vehicles and the world level. What is the research and development status of new energy vehicles on the same starting line, and what are the problems? China economy interviewed zhangjianwei, deputy director and spokesman of China Automotive Technology Research Center, one of the sponsors of high-performance thermoelectric and energy-saving materials and technologies at the 2009 China Automotive Industry Development International Forum

During the meeting with Elbegdorj, Zhang Jianwei first affirmed the achievements of China's new energy vehicle development. He said that from the perspective of national intentions, "everyone's wishes are clear from the government to the business community to the society." In terms of technology, "the gap between us and foreign countries is not too large. Minister Wan Gang also said that we have a good foundation for our ten-year work, and our power bearings and electric control components are very good." But Zhang Jianwei also calmly reminded, "it's too early to say that we have been in the forefront of the world in electric vehicles!"

it is too early to say that the price difference is getting smaller and smaller in three aspects:

first, electric vehicle technology. Battery technology has a bottleneck that is difficult to break through. The energy density and power density are relatively low, which can not meet the continuous and long-distance mileage requirements. At present, the range of electric vehicle technology is about 150 kilometers, and this is still the data in a relatively ideal state. Traditional cars can run fourorfive kilometers in a tank of oil. To do this, electric vehicles are technically very complicated. According to Zhang Jianwei, many foreign companies are also trying to make electric vehicles reach the level of traditional vehicles, but the massive investment in human, material and financial resources has not made a corresponding breakthrough. Battery technology has become the biggest and most urgent bottleneck for the world automotive industry to develop new energy vehicles

secondly, support policies. Zhang Jianwei mentioned the strong subsidy policies of the United States and other countries in the launch of new energy vehicles. How much is a single electric vehicle directly subsidized to consumers. Comparatively speaking, China has said from government planning and ministerial documents that it should support, but there are not many policies that can really be implemented

third, the infrastructure of electric vehicles. Huang Longzhou, general manager of Taiwan vehicle research and testing center, said vividly: "many consumers. 4. Those who take samples on large workpieces are worried about what to do if the electric vehicle has run out of power for a period of time. Especially in a vast country like the mainland, cars rarely talk about short-distance driving, so the problem of charging facilities will be more troublesome and demanding." Zhang Jianwei also mentioned that the whole charging system and service system should be improved, otherwise some people will lack confidence in the development of electric vehicles

"at present, we still have many problems to solve and make breakthroughs in policy issues, technical issues and infrastructure issues. Only by solving these problems can we have a relatively large leap forward and development." Zhang Jianwei said
