The reporter learned on the 15th that the mandatory national standard “Safety Requirements for Electric Vehicle Power Batteries” organized by the Ministry of Industry and Information Technology was released a few days ago and will be implemented on July 1, 2026. The main contents of this revision include the revised thermal diffusion test, which further clarifies the temperature requirements of the battery to be measured, the power up and down state, observation time, and vehicle test conditions. The technical requirements are to provide a thermal event alarm signal 5 minutes before ignition or explosion, and adjust to no fire, no explosion, no harm to passengers, etc.; a new bottom impact test to check the protective ability of the bottom of the battery after being hit; and a safety test after the quick charge cycle. An external short circuit test is carried out after 300 fast charging cycles, requiring no fire or explosion, etc.
