Every four years, the battery energy density of new energy vehicles is doubled, and the cost is reduced by about 50%

Abstract: on the road of improving the global environment and coping with the energy crisis, the transportation field is still facing arduous challenges. It is hoped that in the future, more cooperation can be carried out with California to jointly promote the development of electric vehicles, promote the green development of the whole society, and lead the sustainable development of transportation and society

based on the "made in China 2025" national plan, the automotive industry officially released the "technology roadmap for energy-saving and new energy vehicles" in 2016. According to the goal of the technology roadmap, only one layer can be extended down to 2. By 030, the production and sales of new energy vehicles in China should reach more than 40%. Wan Gang, Minister of science and technology, pointed out that this poses new challenges and opportunities for the development of new energy automobile industry

on June 6, 2017 international electric vehicle demonstration cities and Industrial Development Forum was held in Beijing. As one of the important side meetings of the eighth clean energy Ministerial Conference and the second innovation mission ministerial conference, Wan Gang introduced the current situation, opportunities and challenges of China's new energy vehicles

China's new energy vehicles account for half of the world

Wan Gang said that the just past 2016 was a key year for China's new energy development. With the joint efforts of all parties, the output of China's new energy vehicles exceeded 500000 at the end of last year, and the ownership exceeded onemillion, accounting for 50% of the world

in terms of vehicle technology, China's new energy vehicles have made significant progress. The driving range of pure electric mainstream vehicles has reached more than 250 kilometers, and the plug-in hybrid ensures a driving range of pure electric zero emission of more than 50 kilometers. Although the state has given financial subsidies, the device can quickly lay the materials into the desired three-dimensional shape. After the subsidy, the goal is to remove the polishing damage layer. The cost and sales price are also declining. The integrated and electric chassis, lightweight and intelligent technologies have been gradually applied

in terms of key parts, the industrialization of power batteries has developed rapidly. Since taking the lead in large-scale development of electric vehicles in 2010, the battery energy density of electric vehicles can be doubled every four years or so, and the cost can be reduced by about 50%. At present, electric vehicles are gradually developing towards ideal products that can fully compete in the market in the future, and the policies are constantly changing

at the same time, Wan Gang proposed that promoting the faster industrialization of electric vehicles is not only to solve the problems of technology and industrialization, but also to solve the problems of system and mechanism, among which the demonstration, application and promotion are very important. As Shanghai was identified as an international demonstration city of electric vehicles in 2011, Jiading District is an international demonstration area of electric vehicles. Over the past six years, Shanghai has exceeded 100000 electric vehicles, becoming the world's largest new energy vehicle ownership city. Jiading electric vehicle international demonstration zone has also entered the 2.0 era of promotion and application from demonstration

how to view the development of fuel cells, which is concerned by the industry. Wan Gang pointed out that both are considered together in the planning. Both electric vehicles and fuel cell vehicles are driven by electricity and achieve zero emissions at the same time. In the future, if fuel cell vehicles become competitive and hydrogen is cheaper, fuel cells will be expanded. If the battery has advantages, make it larger. Promoting these two things together can provide more options for the future transportation field and promote the faster industrialization of electric vehicles

the development of new energy vehicles is a long-term unshakable goal

"the development of new energy vehicles is a long-term unshakable goal". Wan Gang pointed out that urban air pollution is very serious, and electric vehicles are required to contribute to clean air. At the same time, he introduced the problems that need to be solved at present

first, we should overcome the institutional obstacles foreseen in the future. Today's energy relies too much on traditional energy. In the future, we need to make full use of solar energy and wind energy to develop intelligent electricity. At the same time, the development of shared new energy vehicles can contribute to solving the problem of traffic congestion in the future. At present, all local governments at the central level have made clear goals and plans, which can overcome the institutional obstacles foreseen in the future

second, we should remove the obstacles in infrastructure, such as charging difficulties. Where to install the charging pile, whether it can be used by everyone, and how to solve the payment problem need to be considered. At the same time, hydrogen fueled vehicles are the future development direction, and the construction of hydrogen refueling stations also needs to be planned from now on. The car is a partner in people's life, and we must establish feelings with people. "People who drive electric cars will fall in love with them, while people who don't drive electric cars may have some obstacles in their hearts. We need to break these obstacles more."

third, we should pay special attention to the safe operation of electric vehicles. Electric vehicles must be fully considered in terms of their own electrical safety or driving safety. In the future, autonomous vehicle will inevitably be realized in electric vehicles, because the agile response and fast driving required by them can be realized in electric vehicles, which is the best carrier. Safety is the first problem to be solved when connecting electric vehicles and networks. Let everyone know the current situation of automobile parts at any time. In this way, electric vehicles will be safer, more durable and cheaper than traditional vehicles

the fasteners may not be vertical when they are fixed.

fourth, pay attention to the emission reduction effect. Both pure electric vehicles and fuel cell vehicles mainly focus on zero emission during operation. Can they charge more zero emission electric energy in the future. Shanghai demonstration station has started to charge electric vehicles with solar distributed energy. In the future, after the construction of national smart electricity, the battery vehicles can be charged with the electricity generated by solar energy, wind energy, hydropower and biomass energy. In fact, the electricity consumed by more than one million electric vehicles is only about 2% of all renewable energy power generation. There is still a lot of room. At the same time, we should also consider the high efficiency in the manufacturing process of electric vehicles. "Last year, I had the opportunity to visit BMW's I3 production workshop for electric vehicles. The entire manufacturing workshop is only one quarter of that of traditional cars, which can save more materials."

fifth, complete recycling should be done well. In the future, electric vehicles should be fully recycled. The recycling process should be considered in the design of all materials. The battery can be used in the charging station after eight years in the vehicle, and then 100% recycled. The value generated by extending the service life should be shared with the owners of electric vehicles

Wan Gang stressed that the transportation sector still faces arduous challenges in improving the global environment and coping with the energy crisis. It is hoped that in the future, more cooperation can be carried out with California to jointly promote the development of electric vehicles, promote the green development of the whole society, and lead the sustainable development of transportation and society
