The Equipment Industry Department of the Ministry of Industry and Information Technology organized the National Automobile Standardization Committee to compile the key points of new energy vehicle standardization work in 2019. The work points clarified five key research areas, including electric vehicle safety, electric vehicle energy consumption, fuel cell electric vehicles, charging facilities and hydrogenation systems, and power battery recycling.

　　The work points point out that the new energy vehicle standard system must be continuously optimized. Establish a system framework that coordinates mandatory and recommended national standards for new energy vehicles, accelerate the construction of standard subsystems such as fuel cell electric vehicles and power battery recycling, and formulate the "New Energy Vehicle Industry Development Plan (2021-2035)" Taking this opportunity, we will conduct in-depth research on the integration development trends of new energy vehicles and energy, transportation, communications, etc., and continuously optimize and improve the new energy vehicle standard system.

　　At the same time, the work points also pointed out that the electric vehicle standardization roadmap must be updated in a timely manner. According to the current status of industrial development and actual needs, and combined with the progress of standard projects under development, the "China Electric Vehicle Standardization Work Roadmap" will be revised in a timely manner to maintain timeliness, scientificity and accuracy, and continue to play the roadmap's basic supporting role in the standard system.

　　The work points pointed out that key areas should be studied to meet the needs of industrial development. The work points clarified five key areas:

　　In addition, the work points emphasize the need to strengthen international participation and enhance international influence:

　　The first is to deeply participate in the formulation of global technical regulations. Fulfill the duties of vice chairman of the working groups on electric vehicle safety (EVS), electric vehicles and the environment (EVE) and fuel cell electric vehicles (HFCV) under the framework of the United Nations World Vehicle Coordination Forum (WP29), and continue to be deeply involved in the third session of electric vehicle safety Research and verification of global technical regulations such as Phase II and hybrid vehicle power test methods, and organize and host the sixth fuel cell electric vehicle working group meeting.

　　The second is to actively participate in international standardization work. Systematically participate in the formulation and coordination of international standards for electric vehicles under the framework of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), actively organize and convene expert meetings for international standard registration, organize the development of international standard proposals, and continuously increase my country's efforts in electric vehicles. Participation in relevant international standards such as conductive charging, wireless chargers and electric motorcycles.

　　The third is to continue to strengthen international exchanges and cooperation. Utilize established bilateral cooperation mechanisms such as China-Europe, China-Germany, China-France, China-Japan, etc., as well as multilateral exchange platforms such as APEC and the “Belt and Road Initiative” to continue to strengthen research and development in key areas such as electric vehicle safety, energy consumption, key components and charging infrastructure. Exchange and cooperation, jointly carry out relevant technical research and testing verification work, and support the coordinated advancement of domestic standards and international standards and regulations.
