No more fireworks: China rewrites the rules for electric cars

From July 1, 2026, China enforces the world's strictest EV battery safety standard. GB 38031-2025 bans fire and explosion after thermal runaway.

China is preparing one of the toughest pivots in electric vehicle safety. From July 1, 2026, new mandatory standards take effect: the traction battery must withstand crash scenarios without catching fire or exploding, and the high-voltage system must shut down physically and reliably.

The key change concerns standard GB 38031-2025. Previously, manufacturers only had to provide a warning before a dangerous thermal event. The approach is now different: even during thermal runaway, the battery must not catch fire or explode. Stricter tests are also being introduced for bottom impact, fast charging cycles, and protection of cabin occupants from smoke.

This will hit not only weak manufacturers but also those who bet on a fast rollout of models without deep engineering refinement. The Chinese market grew too quickly: powerful batteries, ultra-fast charging, dense packaging, and a price war all increase the risk of compromises. The new standard forces companies to prove safety through testing, not advertising.

The second important block is the physical disconnection of power. After a crash, the EV must be readable to rescuers and the owner: where to cut the high-voltage system, how to open the doors, how to avoid secondary risk. This brings EVs closer to the logic of conventional cars, where firefighters and service crews have long known the basic operating scenarios.

For buyers, the new rules are useful in a simple way: Chinese EVs and hybrids will become more expensive to develop but safer by design. This is especially important for vehicles with large batteries, fast charging, and complex electronics.

For import markets it is also a signal. Most new EVs and hybrids come from China, so local Chinese standards effectively become a quality filter for those markets as well. If a car has passed the new requirements, that is a stronger argument than a flashy screen or CLTC-rated range.

China no longer wants to be only the fastest electric vehicle market. Now it is trying to become a market where the battery is obliged to survive a crash without a fiery show.
