There are nearly 40 domestic manufacturers, distributed in Shandong Shifeng, Hongxing and other companies, with an annual output of 10,000 vehicles; Jiangsu Yigao, Xinri Yade and other companies with an annual output of 20,000 vehicles; Fujian Sanxie, Hailong and other companies with an annual output of 5,000 vehicles; other provinces and cities with an annual output of 10,000 vehicles. In 2008, the domestic output was expected to be nearly 50,000 vehicles, of which 20% were exported. II. Reasons for vigorously developing electric four-wheeled vehicles (1) Energy shortage and pollution emissions. China's economy has continued to grow rapidly for many years, and energy consumption has also increased dramatically. Taking oil as an example, China has become the world's second largest oil importer. In 2006, China's dependence on foreign oil exceeded 40%, and in 2010, China's dependence on oil imports was expected to reach 50%. The energy situation is very serious. At the same time, improving the environmental situation is also very urgent. (2) Energy conservation in transportation The National Development and Reform Commission issued my country's first "Medium and Long-Term Special Plan for Energy Conservation". According to the plan, by 2010, my country's energy consumption per 10,000 yuan of GDP will drop to 2.25 tons of standard coal. Vehicle energy conservation should be reduced from an average fuel consumption of 9.5 liters per 100 kilometers in 2000 to 6.7 to 8.2 liters in 2010. (3) State Grid Corporation The State Grid Corporation has begun the electrification and research and development of electric engineering vehicles, official vehicles and electric marketing vehicles, aiming to promote the application of electric vehicles. The detailed vehicle replacement and operation plan for the "Eleventh Five-Year Plan" period, as well as the optimized design scheme for the replacement of electric power engineering vehicles, have been implemented in pilot areas in Beijing, Shanghai, Tianjin, Shandong, Zhejiang, Hubei and Hunan provinces (cities) according to the plan. The State Development and Reform Commission has launched a demonstration operation of 1,000 buses on special lines in 10 cities and expanded the scope of operation. (4) The National Development and Reform Commission issued the new energy vehicle access rules, which divides them into three different technical stages: the initial stage, the development stage and the mature stage. Different management methods are adopted for products at different technological stages: Products in the initial stage can only undergo small-batch trial production and demonstration operation within approved areas, scopes, and conditions; products in the development stage are allowed mass production but can only be sold and used within approved areas; mature products are managed in the same way as conventional automobiles, and their sales and use are the same as conventional road motor vehicles. The Ministry of Industry and Information Technology, the Ministry of Science and Technology, and the National Development and Reform Commission are about to release policies to encourage new energy vehicles. It is predicted that if 10% of the 10 million cars sold annually are hybrid vehicles, China could save 720 million liters of fuel and reduce carbon dioxide emissions by 2.3 million tons per year. 27 domestic automobile companies have developed 76 types of new energy sedans or buses. The Ministry of Science and Technology is actively promoting the development of new energy vehicles, including organizing and implementing the National Energy-Saving and New Energy Vehicle Promotion and Demonstration Project, promoting large-scale application, and initially promoting more than 30,000 energy-saving and new energy vehicles in public facilities such as buses, taxis, government vehicles, municipal vehicles, and postal vehicles. (5) The National Development and Reform Commission (NDRC) said that China will reduce the energy consumption of all automobiles by 15%. Minister of Commerce Chen Deming recently revealed at the Boao Forum for Asia International Conference Center, when answering questions on the forum "How Asia can cooperate to ensure energy security", that China will promote electric vehicles to benefit the environment. According to Hong Kong's Ta Kung Pao, Chen Deming said that in order to further strengthen environmental protection, from 2003 to 2010, the energy consumption of all automobiles in China will be reduced by 15%. (6) The driving effect of large-scale international events is obvious: 500 clean energy vehicles were used to transport athletes from apartments to competition venues during the 2008 Beijing Olympics; the 2010 Shanghai World Expo; the 2010 Guangzhou Asian Games; the 2011 Shenzhen Universiade; and the 2010 Shenzhen World Electric Vehicle Congress. (7) The R&D environment has improved and the industrialization environment is good. Following the small amount of R&D investment during the "Eighth Five-Year Plan" and "Ninth Five-Year Plan", RMB 880 million was invested in electric vehicles during the "Tenth Five-Year Plan". During the "Eleventh Five-Year Plan", the state, local governments and enterprises invested a total of RMB 2.5 billion in R&D and industrialization and commercialization. (8) Significant progress in key component technology: ● Nickel-hydrogen power battery of Chunlan Group ● Lithium manganese oxide power battery of Beijing Mengguli Company ● Lithium iron phosphate power battery of Suzhou Xingheng ● Lithium-ion battery of Tianjin No. 18 Institute ● Lithium-ion battery of Dalian Institute of Chemical Physics ● Lithium-ion battery of BYD ● The rapid development of light electric vehicles has greatly promoted the development of power supply, motor drive and transmission integration technology. In the key component technology of small cars, complete independent intellectual property rights have been basically achieved. (9) Large enterprises secretly compete with each other: According to our understanding, relevant enterprises have completed and are conducting feasibility and technical solution demonstrations on energy-saving and new energy vehicles, and some have taken the lead in implementing them or have made great progress. In particular, electric MPVs, electric micro cars and electric sedans and electric buses have become the main targets of competition. In some provinces and cities such as Shandong, Jiangsu, Zhejiang and Guangdong, there are more than 40 small electric four-wheeled vehicle enterprises that are researching and producing them. Small electric four-wheeled vehicles have been tacitly allowed to drive on the road in some places. Battery rental model, fast battery replacement, night charging and other guarantee measures are gradually being improved. (10) Opportunities and Potential Pressures in Carbon Dioxide Emission Reduction According to the targets set forth in the Kyoto Protocol, member states of the Kyoto Protocol were required to complete their carbon dioxide emission plans (ETS) for the period 2008-2012, meaning that developed countries were required to reduce their emissions by an average of 5.2% compared to 1990 levels. China, as a developing country, was not required to undertake carbon dioxide emission reduction tasks during this period. Countries that were required to undertake emission reduction obligations could purchase emission reduction credits from other countries. Therefore, we could sell emission reduction credits. Some foreign companies have already reached emission reduction purchase agreements with Chinese companies. In the long term, the potential pressure of carbon dioxide emission reduction is enormous, and we cannot avoid undertaking emission reduction obligations. (11) Obvious Trends The development of western China and the construction of new socialist countryside have provided a good development opportunity for electric four-wheeled vehicles. In particular, with the rise in oil prices and the expectation of the implementation of fuel tax, coupled with the limited availability of fuel, the transportation problems in new socialist countryside have come into people's view. It is impossible to solve the transportation problems of the new socialist countryside entirely with fuel-powered cars. Electric bicycles alone cannot meet people's personalized transportation and diversified production requirements. Small electric four-wheeled vehicles, mainly used for passenger and freight transport, have huge market potential in small and medium-sized towns and rural areas in the west. (12) Energy conservation and emission reduction have received high-level attention. The "Eleventh Five-Year Plan" put forward the goals of energy conservation, consumption reduction and pollution reduction, which are of great and far-reaching significance for building a resource-saving and environmentally friendly society, optimizing the industrial structure, adjusting the product structure, transforming the development mode, improving people's quality of life, and safeguarding the long-term interests of the Chinese nation. The National Development and Reform Commission, together with relevant departments, also formulated the "Comprehensive Work Plan for Energy Conservation and Emission Reduction", which was approved by the State Council. The State Council decided to establish a leading group for energy conservation and emission reduction, with Premier Wen Jiabao as the group leader and Vice Premier Zeng Peiyan as the deputy group leader. This will surely greatly promote the development of energy-saving vehicles.
