China's New Battery Safety Standards Take Effect July 1, Raising Bar from "5-Minute Warning" to "No Fire for 2 Hours"

China's New Battery Safety Standards Take Effect July 1, Raising Bar from "5-Minute Warning" to "No Fire for 2 Hours"

Starting July 1, 2026, two mandatory national standards—GB 38031-2025 "Safety Requirements for Power Batteries of Electric Vehicles" and GB 18384-2025 "Safety Requirements for Electric Vehicles"—officially took effect in China. The new standards dramatically raise the safety threshold from the previous "5-minute warning before thermal runaway" to "no fire or explosion for at least 2 hours after thermal runaway," while adding bottom impact tests and post-fast-charging safety tests. Industry observers have called this the "strictest battery safety mandate in history," signaling China's entry into a "zero tolerance" era for battery safety.

New EV Safety National Standards Effective July 1, Introducing First Physical One-Touch Power Cut Device

New EV Safety National Standards Effective July 1, Introducing First Physical One-Touch Power Cut Device

The Electric Vehicle Safety Requirements (GB18384-2025) and Power Battery Safety Requirements (GB38031-2025) will take effect on July 1, 2026. The new standards首次 define the one-touch power cut device as a physical disconnect, replacing software-controlled shutdowns and establishing dual defense for EV safety. National NEV ownership reached 43.97 million by end-2025, with May 2026 penetration at 56.9%. CATL Chief Scientist Wu Kai stated that after implementation, China's NEV spontaneous combustion rate will be an entire order of magnitude lower than combustion vehicles. For Central Asian and Russian markets importing Chinese NEVs, stricter safety standards mean higher safety margins for exported products, helping build trust in overseas markets.
