The new reality: Mastering China's GB38031-2025 battery safety standard
The landscape of electric vehicle (EV) safety is shifting. China’s new GB38031-2025 standard, often referred to as the "No Fire, No Explosion" standard, is changing everything for manufacturers. With China controlling 75% of global battery production, this standard isn't just a local regulation—it’s a global benchmark that will soon spread worldwide.
Technical advantage: Meeting the "Zero Tolerance" Policy
The new requirements introduce a zero-tolerance policy: under any thermal runaway scenario, there must be no fire and no explosion. Here is how FLEXOO sensing technology enables next-generation Battery Management Systems (BMS) to meet these goals:
| Feature | How it solves the GB38031-2025 challenge |
|---|---|
| Cell-level precision | Detects internal failures before thermal runaway begins. |
| In-situ design | Ultra-thin additive printing integrates into packs without requiring redesign of battery pack and assembly process. |
| Real-time response | Instant data transmission allows for proactive BMS intervention before limits are approached. |
| Mass production | A proprietary manufacturing process delivers a cost-effective solution. |
Summary: Staying in China's battery game
To maintain access to the world's largest battery market, manufacturers must adapt to the three pillars of the new standard:
- New test protocols: Standards now include bottom impact, post-fast-charge short circuit, and thermal diffusion tests.
- Zero tolerance: "No fire, no explosion" is the mandatory limit for all thermal runaway scenarios.
- Proactive intervention: Safety must be managed at the cell level with unmatched accuracy.
