CNAE's 138Ah LFP cell for Hongqi Tiangong 08 withstood 145°C continuous heat exposure for 30 minutes without thermal runaway, with nail penetration, extreme short circuit, and 3D compression all passing safely. Multiple indicators far exceed the new GB standard requirements.
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.
On July 1, 2026, two mandatory national standards—GB 38031-2025 and GB 18384-2025—officially took effect. The new standards upgrade thermal runaway requirements from "5-minute warning before fire" to "no fire, no explosion," marking the strictest battery safety mandate in industry history.
The world's first new energy vehicle electrical safety verification system has been officially released, proposing three core safety goals: zero spontaneous combustion, zero thermal runaway, and zero fatalities. The system covers 12 verification dimensions including battery safety, charging safety, and crash safety, led by CATARC and filling the gap in international NEV safety verification standards.
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.
On June 7, 2026, a Xiaomi SU7 Ultra caught fire on the Hero Bridge in Nanchang, Jiangxi Province. Xiaomi's official statement confirmed that backend data analysis showed the power battery remained in normal working condition throughout the incident, with no thermal runaway signals detected, preliminarily ruling out battery self-ignition as the cause. The specific cause awaits further investigation by fire authorities.
On May 16, 2026, a vehicle fire occurred in BYD's Pingshan headquarters garage. BYD officially stated it was "not caused by Blade Battery" but by a short circuit in a modified vehicle's wiring. With China's NEV fleet exceeding 28 million units as of May 2026, battery safety standards are shifting from "corporate self-discipline" to "regulatory mandates."
