Announcement of the New GB Standard GB/T 31486-2024 for Electric Vehicle Batteries
30. September 2024On September 29, 2024, it was announced that 511 new or updated national GB standards had been approved by the State Administration for Market Regulation (Standardization Administration of China – SAC).
As part of this update, the GB/T 31486-2015 has also been renewed. The new version of the standard, GB/T 31486-2024, which sets the requirements for electrical performance and testing methods for electric vehicle traction batteries, will be implemented on April 1, 2024. This standard will apply to all new registrations from April 1, 2025, and will replace the previous version.
Product testing (MIIT or CCC) and marking requirements for cells/modules/packs are mandated for whole vehicle homologation in China. With the new revision, testing requirements are shifted from module to cell level. Additionally, the definition of “modules” has been removed from the new standard, which may directly impact coding requirements according to GB/T34014.
Currently, there is no final information available regarding transition periods for existing cells and modules.
