The demonstration application of “Ten Cities One Thousand Vehicles†will drive related investment in R&D and production of key components of new energy vehicles, form a good development trend of technological breakthroughs in key components, expansion of production scale, and reduction of production costs, thereby promoting the industrialization of new energy vehicles in China. The relevant government departments are also preparing to further formulate industrial development plans and industrial incentive policies for key components of new energy vehicles. The upsurge caused by new energy vehicles continues to heat up this summer. At the recent International Symposium on the Development and Application of Power Storage Batteries and Electric Motors for Electric Vehicles, representatives from the Ministry of Science and Technology, the Ministry of Industry and Information Technology, the National Development and Reform Commission and other government agencies and representatives of new energy auto vehicles and key parts and components companies The status quo and trends of key spare parts for new energy vehicles, such as batteries, drive motors, and super capacitors, were thoroughly discussed, and opinions were fully exchanged on issues such as clarifying industrial needs, strengthening independent innovation, accelerating standard formulation, and creating a policy environment. Delegates believe that our government should give more attention and support to key components of new energy vehicles, create a good atmosphere for the introduction of various new technologies, and regard the industrialization of new energy vehicles and their key components as a response to the international financial crisis. Maintain a new economic growth point where the economy develops steadily and rapidly, and cultivate and seize the commanding heights of a new round of international competition. Key energy component manufacturers of new energy vehicles should seize rare opportunities for development, target the international frontier, strengthen independent innovation, and actively combine The relevant R&D institutions closely cooperate with the new energy automobile production enterprises and make contributions to the realization of the industrialization of China's new energy vehicles and the strategic transformation of the automobile industry. Industrialization of key components is of paramount importance At present, the technological level and industrialization degree of key parts and components of new energy vehicles are the top priorities of the new energy vehicle strategy. This has reached a consensus in the field of international new energy vehicles. The world’s major auto-producing countries regard the development of new energy vehicles as an important strategic measure to cope with energy and climate issues, promote the sustainable development of the transportation industry, and respond to the international financial crisis, and the technical level of key components of new energy vehicles such as power storage batteries and motor systems. The degree of industrialization directly affects the industrialization of new energy vehicles. In order to break through the technological bottlenecks of key components of new energy vehicles and promote its industrialization, major energy-consuming automobile manufacturers such as the United States, Japan, and Germany have recently formulated industrial incentive policies for key components of new energy vehicles and increased investment in R&D production. Specific development plans and targets have been formulated, and relevant international industrial alliances and cooperative communities have also been established one after another. The global competition situation of industrial incentives, strong alliances, and market seizures for key components of new energy vehicles has been formed. “The industrialization of key parts and the localization of basic raw materials are the key and bottlenecks for the development of new energy vehicles in China.†Li Wanli, researcher of the Industrial Policy Department of the Ministry of Industry and Information Technology, said that China’s new energy vehicles are supported by the Ministry of Science and Technology. Through continuous research and development during the “10th Five-Year Plan†and “Eleventh Five-Year Plan†period, significant progress has been made in both research and development capabilities and the number of applications, and small-scale demonstration operations have been conducted. New energy vehicles have shown signs of transition from R&D to industrialization. Hybrid cars, pure new energy vehicles, and fuel cell vehicles have shown rapid growth. The core automotive manufacturers and power supply batteries, drive motors, controllers and other core component manufacturers have grown and expanded during several years of promotion and demonstration work. They have introduced a series of products that meet the performance requirements, but as a common key technology, drive motors, batteries, etc. The key components and parts technology, its main indicators such as reliability, cost, and durability, are still unable to meet the needs of the development of new energy vehicles, and have become the main constraints for the development of new energy vehicles. According to Li Wanli, the next industrialization of the Ministry of Industry and Information Technology will focus on the industrialization of key components and components, power batteries and drive motors, and the localization of basic raw materials. In research and development, China's new energy vehicle "three vertical and three horizontal" strategic R & D system has been continuously improving with the progress of research and development, and now the focus has been on key components. Director Ouyang Minggao of the State Key Laboratory of Automotive Safety and Energy, Tsinghua University, and leader of the Expert Team of the National 863 Program for Energy Conservation and New Energy Vehicles, said that during the Tenth Five-Year Plan period, new energy vehicle R&D was mainly to adjust the lead, and then slowly The transition to the power system platform as the core, and now further transition to the power system module as the core. "In the initial stage, the parts and components companies had just entered the automotive industry. They didn't know anything. They had to take the lead with the whole vehicle and take the parts and components. We spent 3-5 years at this stage. In the second phase, we found that it was completely led by the vehicle. The method did not meet the needs of development, so the power system platform was highlighted as the core; now entering a new phase, when new energy vehicles begin to demonstrate on a large scale, we find that parts and components cannot keep up with the requirements of the power system and the vehicle. The key power system module batteries, motors, and electrical control are the core,†said Ouyang Minggao. In fact, after many years of research, the core technologies of key components for new energy vehicles in China have achieved breakthroughs: At present, China's independently developed Ni-MH, Li-ion power batteries have significantly increased energy density and power density, and are close to the international advanced level; The following 200kW permanent magnet brushless motors, AC asynchronous motors and switched reluctance motors have a weight ratio of more than 1300W/kG, which is compatible with the entire vehicle. However, compared with developed countries, China's new energy vehicle key component technology still has obvious deficiencies or gaps, such as the controller's power switching components and high voltage capacitors. "As far as the motor is concerned, the power battery is a bigger bottleneck. China is lagging behind in terms of battery technology research and development, battery management system and product consistency, reliability, service life, and industrialization." Jingjin Electric Technology (Beijing) Co., Ltd. Chief Technology Officer Dr. Cai Wei said that with the strong support of the government, through the joint efforts of the industry, China's new energy vehicle motor has the greatest potential to become the center of industrialization in the world. Dr. Huang Youyuan of the School of Chemistry and Molecular Engineering of Peking University believes that “the biggest problem at present is the battery management system. Although there has been some progress in the country, there is still a big gap compared to Japan, and the battery management system independently researched and developed is still subject to practical inspections. very short." It is worth mentioning that with the introduction of a series of favorable policies of the country, the enthusiasm of the entire industry chain of new energy vehicles has been mobilized. At the forum for new energy auto parts and components that reporters participated in this year, more and more vehicle manufacturers have appeared. “The vehicle manufacturers and key component companies have begun to sit together and put forward their own needs and solutions to jointly promote the development of new energy vehicles.†Changan Automobile related responsible person said. Faced with development opportunities, all parties need to jointly promote “China's key components for new energy vehicles are facing good opportunities for development and will enter the stage of rapid industrialization in the next 3-5 years.†Industry insiders believe that the demonstration application scale of 60,000 vehicles in four cities will boost the new scale The related investment in R&D and production of key components of energy vehicles has formed a good development trend of technological breakthroughs in key components of new energy vehicles, expansion of production scale, and reduction of production costs, thereby promoting the independent innovation and industrialization of China's new energy vehicles. The relevant government departments are also stepping up investigations and demonstrations to prepare for the further formulation of industrial development plans and industrial incentive policies for key components of new energy vehicles. According to incomplete statistics, China has formed about 1800 patents in the three core technologies of new energy vehicle batteries, motors, and electronic control. In terms of the batteries of the top three core technologies, China has a battery industry cluster consisting of thousands of companies. The output of low-power lithium batteries accounts for one-third of the global market, but the upgrading and transformation of vehicle-powered batteries still requires arduous efforts. Work hard. To this end, Ouyang Minggao suggested: In the research and development, the new energy vehicle power system will be included in the national major science and technology major projects; at the same time, comprehensively strengthen the technological transformation and industrial restructuring efforts, and set up a cross-industry industrial technology innovation alliance to jointly promote industrialization. Zhang Shulin, chief advisor of the China Automotive Technology and Research Center and leader of the energy-saving and new-energy automotive technology policy project team, believes that China should focus on high-performance power batteries, drive motors, and its control systems, focusing on advanced power batteries such as lithium-ion batteries. , To increase its energy and power density, cycle life, system reliability and rapid charge capacity, and further reduce costs, the battery cycle life has recently reached more than 2,000 times, the long-term reach more than 5,000 times; vehicle drive motor key development has a resource advantage Permanent magnet motors increase the power density, efficiency, life and reliability of drive motors, reduce product costs, and gradually form standardized and serialized products. Zhu Yanchun, general manager of Harbin Coslight Power Co., Ltd. put forward four suggestions for promoting the development of new energy vehicle power batteries: First, the country should formulate industrial development plans for key components such as lithium-ion battery for new energy vehicles, and encourage small and medium-sized enterprises and private enterprises. Enterprises should participate in the market, introduce new energy vehicle market access policies as soon as possible, relax the licensing conditions for new energy vehicles, in particular, they should actively support the development of large-scale bus new energy buses, small-scale low-speed new energy cars and special new energy vehicles; second, the state should start with fuel every year. A certain percentage of funds are drawn from taxes and emission reductions to support the research, development, and industrialization of key parts and components such as lithium-ion power batteries, form a complete industrial chain that integrates upstream and downstream as soon as possible, and increase the incentive for new energy vehicles. The input of battery standard research, the development of new energy vehicle power battery industry has a lot to do with the level of standards and the speed of advancement. China's new energy vehicles must lead the world and must be the standard first; Fourth, the establishment of new energy vehicle battery country Open laboratory can absorb powerful companies and machines As its members, experimental equipment and experimental data are conditionally shared, and free testing is conducted on the power batteries of new energy vehicles for member companies.
