The future of EV safety just got a major upgrade in China
The Ministry of Industry and Information Technology (MIIT) has officially released a new version of the mandatory national standard – GB38031-2025: Safety Requirements for Power Batteries for Electric Vehicles – set to take effect on July 1, 2026.
Here’s what stands out:
1. Stricter Safety Tests
The new standard introduces 7 cell-level tests and 17 pack/system-level tests, significantly raising the technical bar. Key additions include:
• Bottom Impact Test – evaluates protection after underbody impacts.
• Post-Fast-Charging Cycle Safety Test – assesses safety after 300 fast-charging cycles.
• Thermal Runaway Propagation Test – revised to ensure no fire or explosion, with smoke not harming passengers.
2. Smarter Safety Standards
The original rule required a 5-minute warning before fire/explosion.
Now, no ignition is allowed at all, although alerts are still mandatory.
This is a huge leap forward in EV thermal management expectations.
3. Transition Timeline
• New vehicle type approvals: Must comply by July 1, 2026.
• Existing approved models: One-year grace period – upgrade or phase out by July 1, 2027.
Why this matters:
This move is not just about stricter regulation – it’s about restoring public confidence in EV safety, especially with recent concerns over battery fires.
At the same time, it may bring short-term challenges, especially for small and mid-sized players, potentially reshaping the industry landscape toward greater consolidation and standardization.
My take:
This is a necessary step for long-term sustainability and consumer trust in electrified mobility.
For industry players, now is the time to double down on safety innovation and compliance readiness.
✍️ What do you think – will these stricter standards accelerate EV adoption or slow it down in the short term?
