What changed in China's mandatory vehicle standards — explained for engineers
China's new mandatory standards for EV batteries, EV safety, cybersecurity and OTA apply to new type approvals from 1 July 2026. Already-approved models follow later. We publish independent English diff reports: what changed versus the previous edition, what it means for your BMS, pack and test plan, and a checklist of the evidence you need.
First report: GB 38031-2025 vs GB 38031-2020
Thermal propagation now "no fire, no explosion", a new 150 J bottom-impact test, a new 300-cycle fast-charge safety test, and a full clause-by-clause change map.
