General Secretary Xi Jinping said that the development of new energy vehicles is the only way for my country from the automotive power to the strong country. Power lithium battery technology can not occupy the high school, has become the focus of the competition in the world's new energy automotive industry. Currently, the development of the R & D and industrialization of the power lithium battery in the world is in the three regions, located in Germany, the United States, and China and Japan.
my country's battery company has the largest number of battery companies, but also needs to improve competitiveness in technology. On March 30th, 31 days, in my country, China's new energy vehicle talent training base, for the current status, policy regulations, standard systems, research and development test processes and methods of my country's powered lithium battery, and development of electric vehicles and key components The personnel carry out advanced training in the dynamic lithium battery. This training highlights are important to focus on power lithium batteries, deeply explained the knowledge of this key component, important involving the pilot lithium battery monomer and module system group technology, safety Analysis and evaluation, recycling technology, etc.
As we all know, the parts are strong, which is strong, because of the relatively weakness of the parts of the parts, leading to my country's auto industry in a large state, so Dong Jianping, executive vice chairman of my country's Automobile Engineering Society Parts Industry Research Association, believes that The development of new energy auto parts cannot repeat the traditional auto industry does not pay attention to the number of parts, and ultimately causing the joint venture to seize the market, independent brands are marginalized. With the resurface of new energy subsidies, the pressure of new energy auto market is increasingly urgent, the most severe test is cost problem, and the power lithium battery is responsible for. Whether it is a battery company or a vehicle company, it should be aware that when the government's purchase subsidy is faded out, it is the daily foreign capital and joint venture brands entering our market.
Wu Zhixin, deputy director of my country's Automobile Technology Research Center, believes that industrial transformation and upgrading must have its own research and development advantage. At present, my country's parts are weak, but the development of new energy vehicles in China may reverse this situation, and master technology advantages in new energy batteries. It is possible to achieve curve overtaking, in order to develop a rapid lithium-ion power lithium battery market, BYD, CATL, Watma and other companies have shown a strong offensive.
In addition, Wu Zhixin surrounds the research background, new energy automotive battery and fuel power battery technology in China and foreign countries, the development trend, the vision target, development route, and interpret the new energy vehicle technology road map. He put forward that my country's inheritance of the battery and management system, the large-scale production control capacity and system integration ability are still behind foreign countries, the target setting and functional decomposition work of the vehicle is not systematic; in the electromechanical coupling system And abroad gaps are obvious, showing behind integrated design capabilities and input speed range; and fuel power battery in foreign gaps behave low, high cost, catalyst, and proton exchange membrane, etc. my country's powered lithium battery industry should have a great effort in technical level, industrial capacity, infrastructure.
About the power lithium battery system test, the chief expert of my country's Automobile Technology Research Center Wang Fang, Yang Guanke, Minister of Engineering, Beiqi New Energy, CATL Products R & D Director Hu Jianguo explained from standard regulations, key performance evaluation requirements, safety analysis. According to a report, the Ministry of Industry and Information Technology is being revised on the powerful threshold of the powerful lithium battery. The new access standards are set in terms of production, production conditions, technology research and development capabilities.
Wang Fang said that the relevant departments will discuss new on April 6th. The development of GB standards, perhaps new access standards will refer to the day. Based on a large number of experimental data, Wang Fang's standardization system, safety test, monomer test evaluation and thermal-electrochemical coupling test evaluation system is detailed.
She said that although the dynamic lithium battery access standard has been changing, the new standard is the adjustment made on the existing national standard, not the change of the earth, and the related company eliminates the product or equipment "halfway waste". About the power lithium battery. Therefore, Beiqi Yang Gongke is based on the current user's important pain, combines the vehicle performance indicators, from energy, power, charging, low temperature, life, and six major aspects to decompose the power lithium battery key performance index.
In response to these performance indicators, Yang Guanke shows the current stage of Beiqi new energy will continue to increase in battery energy density, and continuing to deeply plow in the security field, continuously promote modularity, standardization, and combined with low temperature performance, fast charge performance improvement and improvement user experience. As a very lively high-energy carrier, the powerful high energy carrier can do not have a large amount of damage due to the abnormal state of energy, so it requires energy to electrical energy and chemical energy in a controllable manner. Conversion and flow, high requirements for system integration, based on this, CATL Hu Jianzang combines the characteristics of the power lithium battery and the idea of safety design, summarizing battery system products.
In the past two years, with the soaring of new energy vehicles, the power lithium battery as a new energy vehicle heart also entered the rapid development period, 2020 new energy car insurance will reach 5 million, with sales of sales, must Acknowledging that the waste battery will bring great pressure to the environment. Professor Li Li from Beijing University of Science and Technology demonstrated the huge significance of waste lithium-ion battery recovery from economic and resources, and the method of recovery of lithium-ion batteries from physical law, chemical method and biological law. Since the current recovery efficiency of waste lithium-ion battery is not high, Li Li recommends that the company should establish a sound recycling mechanism from the source, not in the power lithium battery flow into the market "there is no return".
About the design development, analysis and verification of the power lithium battery system, the technology of the safety and intelligent management of battery management system, from China AV, Hangzhou Jieneng Technology, and Warm News Experts also discussed. The advanced training class of electric vehicles and key components hosted by the my country Automotive Talent Research Association, with nearly 200 technical personnel from more than 90 important vehicles, parts companies and research institutions participated in training. my country's Automotive Talent Research Association has been intended to share the relevant experience in the national authority and scientific research and testing agency and excellent company in the actual work and product development testing.
And the rapid and benign development of new energy automotive industries. .
