On May 12, 2020, GB 18384-2020 'Safety Requirements for Electric Vehicles', GB 38032-2020 'Safety Requirements for Electric Buses' and GB 30381-2020 'Safety Requirements for Power Batteries for Electric Vehicles' formulated by the Ministry of Industry and Information Technology The three mandatory national standards (hereinafter referred to as the 'three strong standards') have been approved and promulgated by the State Administration for Market Regulation and the National Standardization Administration and will be implemented on January 1, 2021. The safety of electric vehicles is the focus of consumers' attention and the fundamental guarantee for the sustainable and healthy development of the new energy vehicle industry. In order to implement the requirements of the 'Energy-saving and New Energy Automobile Industry Development Plan (2012-2020)', and the 'Mid- and Long-term Development Plan for the Automobile Industry' and other requirements, combined with the actual development of the new energy automobile industry and the needs of technological progress, the industry and informatization will start electric in 2016 The establishment of three strong standards for automobile safety.
The three strong standards are based on China’s original recommended national standards, and are fully integrated with the United Nations Global Technical Regulations on Electric Vehicle Safety (UN GTR 20) that China has led to formulate, and further improve and optimize the requirements for electric vehicles and power battery products. Safety technical requirements. Among them: 'Electric Vehicle Safety Requirements' mainly stipulates the electrical safety and functional safety requirements of electric vehicles, and increases the battery system thermal event alarm signal requirements, which can promptly remind drivers and passengers of safety; strengthen the waterproof and insulation resistance of the vehicle And monitoring requirements to reduce the safety risks of vehicles in normal use, wading, etc.; optimized test methods such as insulation resistance, capacitive coupling, etc., to improve test detection accuracy and ensure the safety of high-voltage power for the entire vehicle.

'Electric Bus Safety Requirements' aims at the characteristics of large number of passengers, large battery capacity, and high driving power of electric buses. Based on the standard of 'Electric Vehicle Safety Requirements', the conditions for collisions, charging systems, and vehicle waterproofing of the battery compartment of electric buses are tested. And requirements put forward more stringent safety requirements, increase the flame retardant requirements of high-voltage components and the minimum management unit of the battery system thermal runaway assessment requirements, and further improve the risk prevention ability of electric bus fire accidents.

While optimizing the safety requirements for battery cells and modules, the 'Safety Requirements for Power Batteries for Electric Vehicles' emphasizes the thermal safety, mechanical safety, electrical safety, and functional safety requirements of the battery system. The test items cover system heat diffusion, external fire, Mechanical shock, simulated collision, damp heat cycle, vibration in water, external short circuit, over temperature and over charge, etc. In particular, the standard adds the thermal diffusion test of the battery system, which requires that after the battery cell is thermally out of control, the battery system will not catch fire or explode within 5 minutes, so as to reserve a safe escape time for the occupants.
