New energy vehicles: ready to forge ahead

from the German Carl Benz invented the first modern car fueled by gasoline and powered by internal combustion engine in 1885 to American adolphbush successfully manufactured the first diesel car that broke the dominance of gasoline cars in 1899, Then, in 1913, Ford Motor Company first launched an automobile assembly line that could carry out a large number of operations, and the automobile gradually developed in the brewing of human wisdom

nowadays, new energy vehicles represented by fuel cell vehicles, pure electric vehicles, hybrid electric vehicles, etc. come into our life to meet our requirements. New energy vehicles have become a new direction for the development of the global automotive industry

usher in major opportunities for development

in 2009, China's car ownership exceeded 70million, and both production and sales exceeded 13million

behind the figure of 13million, new energy vehicles account for only a small proportion, but we can really feel that it has driven to our side

what does it mean for us to develop new energy vehicles? Perhaps it is more intuitive to explain with figures

a total of 1017 new energy vehicles will serve the Shanghai WorldExpo. During the WorldExpo, it is estimated that about 10000 tons of traditional fuel will be saved, about 118 tons of harmful substance emissions will be reduced, and about 28400 tons of greenhouse gas emissions will be reduced

at present, automobile fuel consumption accounts for about one third of China's oil consumption. It is estimated that China's automobile ownership will reach 150million by 2020. Assuming that new energy vehicles account for 20% of the car ownership at that time, about 30million vehicles can save 50million tons of oil per year, which is equivalent to the annual output of Daqing Oilfield

the number is gratifying and of greater significance

China is an oil importing country, and the huge fuel consumption of cars has increased the pressure on China's energy supply. If 30million new energy vehicles can save a Daqing oil field, the importance of vigorously developing new energy vehicles to alleviate China's oil shortage and reduce oil dependence on foreign countries is self-evident

in addition, traditional cars will emit greenhouse gases and lead compounds during operation. With such a large number of cars in China, the annual exhaust emissions have brought serious environmental pollution. Some data show that about 25% of the global carbon dioxide comes from automobile exhaust; In Beijing, Shanghai and other big cities in China, 50% of air pollution also comes from vehicle exhaust emissions. By adopting new energy and energy-saving technologies, reducing the fuel consumption of cars and reducing the emissions of greenhouse gases and lead compounds is not only the need of energy conservation and emission reduction, but also an important guarantee for achieving sustainable development

Wang Jin, a Beijing girl who served as a volunteer for the Beijing Olympic Games two years ago, has a fresh memory of new energy vehicles. One after another, new energy buses pass by without smelling the usual exhaust fumes of buses. If new energy buses can be used in the future, the air quality in Beijing will be better and better

as far as the automobile itself is concerned, the emergence of new energy vehicles will also hasten a revolution in automotive power technology and drive the upgrading of the automotive industry

zero emission, low noise; The cost of energy replenishment is only one fifth of that of fuel vehicles; The motor has superior torque performance, which makes it more fun to drive; It can give full play to the advantages of motor control and improve the performance of the whole vehicle. The active safety performance that is difficult to achieve in traditional vehicles can be easily achieved on electric vehicles; With the advantage of electricity, it can carry a higher power motor system and build a comfortable driving and riding environment; It is easy to realize the networking control of the whole vehicle, and can be combined with intelligent transportation and intelligent electricity. At the China (Chongqing) International Cooperation Forum on automobile and motorcycle industry held in May this year, Professor Lin Cheng, deputy director of the National Engineering Laboratory of electric vehicles, summarized the six advantages of electric passenger vehicles. He said that the electric passenger vehicle industry is large-scale, and the independent innovation of electric passenger vehicles is an opportunity for China's automotive industry

give full play to advantages and independent innovation

in the view of Wang Binggang, leader of the supervision expert group for major projects of energy saving and new energy vehicles in the National 863 plan, China has many advantages in developing new energy vehicles. First, the research and development started early, and the state attaches great importance to it, and is formulating a series of support policies; Secondly, China's future power supply is relatively sufficient; Third, electric vehicles can be combined with renewable energy and intelligent electricity to cut peak and fill valley for electricity; Fourth, China is rich in lithium resources, with cost and market advantages

in the face of advantages, many automobile related enterprises are eager to try. On the opening day of this year's Beijing auto show, 95 new energy vehicles were released. Geely, Chery, BYD and other independent brands have also unveiled their independently developed new energy vehicles

at the end of March this year, BYD F3DM low-carbon version equipped with the world's first roof solar battery charging system was officially launched. In addition to the world's original DM dual-mode system and iron battery technology, the roof solar battery charging system is also installed. This is a solar panel similar to the panoramic sunroof, which outputs current through the absorbed solar energy and stores it in the iron battery for the driving of the whole vehicle. Solar charging has become the third charging method of F3DM low-carbon version after professional charging stations and household socket charging. It is reported that F3DM low-carbon version is the first to be sold to individuals in Shenzhen, and will be successively promoted to all new energy vehicle pilot cities across the country

the industrialization process of new energy vehicles in China has accelerated significantly. According to incomplete statistics, at present, there are more than 150 complete vehicle enterprises, including FAW, Dongfeng, SAIC, BAIC, Chery, Geely, Lifan, BYD, etc., more than 30 manufacturers engaged in the R & D and production of new energy vehicles, and more and more enterprises are involved in the R & D and production of key components and parts related to new energy vehicles, such as batteries and electric machines

CITIC guoanmeng Guli Power Technology Co., Ltd. is located in Beijing Zhongguancun High Tech Park. It is mainly engaged in the R & D, production and sales of key materials of lithium-ion secondary batteries and high-energy density power lithium-ion secondary batteries. According to the person in charge of the company, mengguli power company is the only supplier of power lithium batteries for pure electric buses for the Beijing Olympic Games. This year, it has provided 116 sets of power battery systems for 60 pure electric buses in the Shanghai WorldExpo park. At the Guangzhou Asian Games, we will also provide 30 hybrid battery systems for new energy vehicles

at the same time, the relevant infrastructure construction of new energy vehicles is also constantly improving

in the second half of last year, CNOOC and China Putian jointly established Putian CNOOC new energy power Co., Ltd., which specializes in operating the energy supply network of electric vehicles. At the beginning of this year, Sinopec Beijing Branch and Beijing Shouke Group Co., Ltd. jointly funded the establishment of Beijing Sinopec Shouke new energy technology company, focusing on the reconstruction of some of Sinopec's existing refueling and gas filling stations into refueling and charging integrated service stations. State Grid Corporation of China and China Southern Power Corporation also take electric vehicle charging stations as strategic priorities. In August last year, with the development of utilization demand, Caoxi electric vehicle charging station, an electric vehicle charging station with commercial operation function invested by Guodian Shanghai company, was successfully completed, and the pilot of electric vehicle charging stations in Shanghai, Tianjin, Xi'an and other cities were also launched one after another

the technical path is basically clear.

we are formulating the development plan of the new energy vehicle industry, which can be promulgated and implemented after being reported to the State Council for discussion and adoption by the end of August. At the ceremony for Shenzhen to take the lead in launching the subsidy for private purchase of new energy vehicles held in early July this year, Miao Wei, Vice Minister of the Ministry of industry and information technology, said that the technical route of new energy vehicles is currently basically determined as a development mode dominated by electric vehicles and the coexistence of various technical routes of new energy vehicles, and the development path of new energy vehicle technology is basically clear

in June this year, the Ministry of finance, the Ministry of science and technology, the Ministry of industry and information technology, and the national development and Reform Commission jointly issued the notice on carrying out the pilot subsidy for private purchase of new energy vehicles, and decided to implement the development strategy of efficient and green plastic granulators in Shanghai, Changchun, Shenzhen, Hangzhou, and Hefei. Five cities officially launched the pilot subsidy for private purchase of new energy vehicles. According to the regulations, the maximum subsidy for each plug-in hybrid passenger vehicle is 50000 yuan, and the maximum subsidy for each pure electric passenger vehicle is 60000 yuan. From this subsidy policy, it can be seen that the national focus on the development of new energy vehicles is pure electric vehicles, while ordinary hybrid vehicles are classified as energy-saving models. Chen Quanshi, director of the electric vehicle branch of the society of Automotive Engineers of China, director of the Automotive Research Institute of Tsinghua University and doctoral supervisor, said

another document issued almost at the same time as the subsidy notice, "detailed rules for the promotion and implementation of energy-saving vehicles in the benefit of energy-saving products project", clearly points out that gasoline and diesel passenger vehicles (including hybrid and dual fuel vehicles) with engine displacement of 1.6 liters or less and fuel consumption under comprehensive working conditions about 20% lower than the current standard are included in the benefit of energy-saving products project and promoted nationwide, The central government will give consumers a one-time quota subsidy of 3000 yuan per vehicle when purchasing energy-saving vehicles, which will be directly cashed by the production enterprises to consumers at the time of sale. The "detailed rules" pointed out that China's automobile development is another vane. In a short time, energy-saving and environmental friendly small displacement vehicles will still be the focus of encouragement

according to the analysis of relevant people, the issuance of the notice and the detailed rules points out the research and development direction for the vehicle manufacturers, that is, pure electric vehicles and high hybrid electric vehicles will receive more policy preferences

although there have been some achievements, we still need to continue to strengthen research and development to promote technological progress. Said xiangchangle, Dean of the school of machinery and vehicles at Beijing University of technology. As one of the first units to carry out the research and technology development of electric vehicles, whose sensitivity is a symbol of measuring physical instruments, Beijing University of technology has been engaged in the development of complete vehicle technology, electric vehicle powertrain technology, electric vehicle demonstration operation and technology promotion of electric vehicles since 1992. At present, it has a national laboratory, It has formed the technical advantages of the electric vehicle industry and a relatively complete system of electric vehicle technology development achievements. We should let technology go out of the laboratory. Xiang Changle said that maybe we are leading in a certain technology or index, but if we consider the whole industrial chain and comprehensive cost, our gap is not small, and we must make technology in a down-to-earth manner

experts believe that the main technical bottleneck of new energy vehicles in China is batteries. It is urgent to develop batteries with low cost, small size, strong sustainability and long service life, which is the key to promote the development of new energy vehicles. In addition, there is no national standard for pure electric vehicles and other alternative fuel vehicles, and the approval and listing of new energy vehicles may encounter a standard blind spot. The national standard will directly affect the future parts matching, production equipment transformation and other aspects, and will also have a great impact on enterprises

on the road of new energy vehicle development, the direction has been pointed out, and the road is at the foot. According to the goal of the plan for the adjustment and revitalization of the automotive industry, in 2012, 10% of the newly produced vehicles will be energy-saving and new energy vehicles, and the output value of new energy vehicles is expected to reach 500billion yuan
