[Two Mandatory EV National Standards Take Effect Tomorrow: Batteries Must Not Catch Fire or Explode]

On July 1, two mandatory national standards—"Safety Requirements for Traction Batteries of Electric Vehicles" (GB 38031-2025) and "Safety Requirements for Electric Vehicles" (GB 18384-2025)—will officially come into force. This marks the first time in China's new energy vehicle sector that both battery‑specific and vehicle‑level core safety standards take effect on the same day.

The new battery standard establishes "no fire, no explosion" as a mandatory requirement, replacing the previous technical threshold of "providing an alarm signal 5 minutes before fire or explosion." The updated standard also adds tests including bottom impact testing and safety testing after fast‑charging cycles. The vehicle standard requires the installation of an independent physical one‑button emergency power‑off device.

The two standards will be implemented in phases: all newly applied vehicle models submitted after July 1 must fully comply with the new rules, while models already approved and on sale are granted a one‑year transition period until full compliance is required by July 2027. Industry players across the supply chain have already entered the final stages of certification review and production‑line retrofitting.
