"At present, the development of green and low-carbon cycle has become the common goal of mankind. New technologies such as artificial intelligence, big data, 5g, etc. are deeply integrated with new energy power generation, electric vehicles, etc. there is an urgent need to formulate and apply international standards in relevant fields and strengthen international cooperation in the field of standards." Recently, the opening ceremony of the eighty-third International Electrotechnical Committee (IEC) conference was held in Shanghai. China's president Xi Jinping made the above instructions when he sent a congratulatory letter to the general assembly. "What President Xi Jinping emphasized in his congratulatory letter is of great guiding significance for the development of new energy vehicles and even the entire automotive industry. This is an important period for the vigorous development of new energy vehicles in China and an increasingly important leading role in the field of new energy vehicles in the world. The importance of strengthening the standard setting of electric vehicles is highlighted." Fu Yuwu, honorary president of China Automotive Engineering Society, said in an interview with China Automotive News. So, to what extent is the new energy vehicle related standard system constructed in China? What is the progress of international cooperation on standards? In this regard, the reporter of China Automotive News has combed and interviewed experts in relevant industries. "The development of China's new energy automobile industry is not only the need of energy conservation and environmental protection, but also the need of future transportation mode reform. Therefore, in order to promote industrial development and accelerate industrial transformation, the construction and improvement of relevant standards is an urgent task. " Yang Shichun, vice chairman of the electric vehicle sub standard committee of the national automobile Standardization Technical Committee and professor of the school of transportation science and engineering of Beijing University of Aeronautics and Astronautics, said in an interview with the China Automotive News that the standard is the right to speak. The formulation of the new energy vehicle standard determines the development and future of the new energy vehicle industry. In recent years, China has formulated and issued a series of policy documents in the management, promotion and application, tax preference, technology research and development, infrastructure, travel priority, etc. of the new energy automobile industry chain, promoting the vehicle enterprises, key parts, charging infrastructure, operation enterprises, upstream material enterprises, downstream after-sales service enterprises, logistics enterprises and Financial service enterprises are gradually improving and maturing. On this basis, according to the policy guidance and the actual industrial development, China has formulated a number of relevant standards. Among them, in the field of electric vehicles, there are more than 120 current standards and more than 50 standards under research, covering electric passenger vehicles, buses and freight cars; it also includes, vehicles (including), electric vehicles, related system components of electric vehicles, as well as infrastructure and interface devices, including, power station and hydrogenation station, industrial chain construction and operation of charging, power exchange, discharge, hydrogenation, etc , management, etc. Among them, only in the safety of new energy vehicles, China has introduced a number of recommended safety standards for electric vehicles in recent ten years. This year, the Ministry of industry and information technology pointed out that it will also issue three compulsory national standards for electric vehicles: Safety requirements for electric vehicles, safety requirements for power storage for electric vehicles and safety requirements for electric buses. "In recent years, China's new energy vehicle industry with electric vehicles as the mainstream has made remarkable progress. On the whole, the industrial development has entered the growth period from the cultivation period, and formed a certain first mover advantage in the global scope. Therefore, it is imperative to formulate and improve relevant standards. " As Wang Binggang, leader of the national new energy vehicle innovation project expert group, said in an interview with China Automotive News, with the development of China's new energy vehicle industry, more and more attention has been paid to the standardization work. "Although some progress has been made in the standardization of new energy vehicle industry in China, there is still a lack of innovation and breakthrough in the overall ideas of relevant standardization work in China. For example, in terms of the safety of new energy vehicles, operating conditions and driving mileage, and the definition of power battery life, there are big differences between the existing standards and the product evaluation in the market, which is not enough to objectively reflect the actual situation The situation. " Say. Indeed, as Wang Binggang said, there are some real needs for standards to be formulated at all levels of the new energy automobile industry. Among the domestic automobile enterprises, no matter SAIC, Dongfeng, and other state-owned enterprises, or, and other private enterprises, as well as Weima, and other new forces in vehicle manufacturing, many automobile enterprises have established a relatively complete positive development system for new energy vehicles. The R & D investment of some new energy vehicle enterprises and power battery backbone enterprises accounts for more than 8% of the sales revenue, which is higher than the international average level of the industry. But the related technical standards are not perfect and clear, which limits the development of industrial technology research to a certain extent. In terms of power mode, China is still the mainstream of pure electric vehicles, accounting for more than 70% of new energy vehicles by conservative estimation. At the same time, there are also automobiles, incremental electric vehicles, battery vehicles and methanol fuel vehicles, which have certain research or application in these fields, but there is no relevant standard system to carry out clear and detailed specifications. In terms of the power battery of electric vehicles, the energy density of the power battery unit of some leading enterprises in China has reached 250 Watt hours / kg, which is 2 times higher than that in 2012, and the technology development speed has the potential to accelerate. However, in addition to some basic standards formulated in previous years, there is a lack of leading standards. In addition, nowadays, many domestic automobile enterprises apply more and more "new four modernizations" achievements to new energy vehicles. Only in the new models released this year, the application of L2 auxiliary system and other new technologies is increasing. The new energy vehicles based on 5g, intelligent Internet connection, high-precision map, vehicle road coordination, automatic driving and other new technologies are lack of relevant technical standard system. In this regard, Wang Binggang suggested that the overall idea of standardization work needs to be adjusted in time to keep up with the needs of technological innovation and change; to study the sources of funds for research and development of new standards and the reform of existing standardization work mechanism; and to give more consideration to the foresight of technological development. "It is of great practical significance to emphasize the urgent need to formulate and apply international standards in relevant fields and to strengthen international cooperation in the field of standards." Shi Jianhua, Deputy Secretary General of China Automobile Industry Association, said in an interview with China Automotive News that standardization is necessary for new energy vehicles to maintain and improve the reliability, consistency and stability of product quality and avoid the non-standard and rough manufacturing of some products. With the development of China's new energy vehicle industry, it is a new trend to actively participate in international standardization. In the field of new energy vehicles, international standardization organizations, such as the international organization for standardization, the International Electrotechnical Commission, the United Nations World Forum for vehicle regulation coordination and other international standardization organizations actively carry out the preparation, revision and coordination of international new energy vehicle standardization within their respective terms of reference. At the same time, the United States, Germany, Japan and other developed countries of automobile industry and the European Union and other regional organizations have their own new energy vehicle standardization organizations. According to their own development needs, they have formulated the corresponding work plan for the standardization of electric vehicles, and actively carried out the standardization revision and coordination work related to electric vehicles. In recent years, with the development of related industries, the research of new energy vehicle technology standards has been widely valued in the world. Two international standardization organizations, the international organization for Standardization (ISO) and the International Electrotechnical Commission, have also significantly accelerated the preparation and revision of relevant international standards for electric vehicles. Among them, the International Electrotechnical Commission has issued 14 relevant standards and is in the process of preparing and revising 16 relevant standards; the international organization for standardization has issued 26 relevant standards and is in the process of preparing and revising 11 relevant standards; the international automobile compulsory regulatory system UN / WP29 has also accelerated the research and revision of the content of the compulsory inspection of electric vehicles. In May of this year, the Ministry of industry and information technology of China issued the key points of new energy vehicle standardization in 2019 (hereinafter referred to as the key points), which proposed that not only the standard system should be optimized, the standard innovation and development should be promoted, the key fields should be studied and the industrial development needs should be met, but also the international participation and international influence should be strengthened. One belt, one road, is to strengthen exchanges and cooperation in key areas such as electric vehicle safety, energy consumption, key components and charging infrastructure, and jointly carry out related technical research and testing and verification, supporting domestic standards and international cooperation in terms of international coordination. It emphasizes the use of established bilateral cooperation mechanisms such as central Europe, China, Germany, China, Japan and China, as well as multilateral exchanges such as APEC and "one belt and one road". Coordination and promotion of international standards and regulations. In fact, with the establishment and improvement of relevant domestic standards system, China also actively participates in international standardization related work. In June of this year, the framework document of autopilot was jointly launched by China, and was jointly approved by Europe, the United States and Japan. It was approved by the 178th plenary meeting of the UN World vehicle control coordination forum. This document contains work guidelines, safety factors related to autonomous vehicles, as well as key issues and principles that need to be prioritized in the formulation and coordination of relevant vehicle laws and regulations, and becomes an important basic document for the formulation of relevant international standards. "China actively participates in the international standardization work related to new energy vehicles. While fully absorbing and drawing on international experience, China can share the achievements of China's Intelligent Networking Association and new energy vehicle standardization with the world, put forward China's plans, contribute to China's wisdom, and jointly promote the technological progress of the world's automobile industry." Yang Shichun stressed. In fact, in the context of increasing international competition, in recent years, many countries and regions have announced the fuel vehicle ban schedule. As a multi-dimensional comprehensive technology across industries, fields and borders, new energy vehicles are becoming an effective solution to reduce energy consumption and pollution in the new environment, and an important pillar to build a clean, green and smart city. Therefore, many industrial powers in the world are protecting industrial development in the form of standards or even regulations. "The content of standardization construction emphasized in the congratulatory letter will play an important role in promoting the standardization of new energy vehicles in China. Therefore, we need to speed up the formulation of new energy vehicle standards, promote the integrated development of new energy vehicles, and accelerate the transformation of China from a big auto country to a powerful auto country. " Point out.
