An updated mandatory national standard on the safety of electric vehicle batteries in China is set to take effect on July 1 next year.
The standard is laid out in "Safety Requirements for Power Batteries Used in Electric Vehicles (GB38031-2025)," according to the Ministry of Industry and Information Technology.
The revisions include updates to thermal diffusion testing of batteries, further clarifying temperature requirements, observation time and vehicle testing conditions.
A new bottom impact test has been introduced to assess the protective capabilities for the battery from impacts to its base.
A new safety test following fast charging cycles has also been added, which requires external short circuit testing after 300 fast-charging cycles, mandating no fire or explosion.
The revised version clearly states that the standard applies to power batteries for electric vehicles, excluding non-propulsion batteries. (Xinhua)
