Big news for the EV industry! China’s Ministry of Industry and Information Technology (MIIT) has just released the official GB 38031—2025 safety requirements for electric vehicle batteries—dubbed the "strictest national battery standard" yet. Why? Because it mandates ZERO fires or explosions, marking a significant leap in battery safety regulations.

Key Updates in the New Standard:

1️⃣ Stricter Thermal Runaway Testing – Batteries must NOT ignite or explode (even after internal short circuits), with no harmful smoke endangering passengers. (Old standard only required a 5-minute warning before fire/explosion.)

2️⃣ New Bottom Collision Test – A 30mm impactor strikes the battery pack 3 times at 150J—no leaks, cracks, fires, or explosions allowed!

3️⃣ Fast-Charge Cycle Safety Test – After 300 fast-charge cycles, batteries must pass an external short-circuit test without catching fire or exploding.

4️⃣ Simplified Approval for Modified Batteries – If a battery design changes, only partial retesting is needed, speeding up new EV launches.

5️⃣ Clearer Technical Requirements – Updates on insulation resistance, vibration, and crush tests for enhanced safety.

⏳ Timeline & Industry Impact

2026.7.1: Mandatory for new EV models applying for approval.

2027.7.1: Deadline for existing models to comply (1-year grace period).

💡 Why This Matters

✔ Safer EVs – No more "5-minute escape window"—just zero fire risk.

✔ Higher R&D Pressure – Battery makers & automakers must invest heavily in safety tech.

✔ Industry Upgrade – Pushes China’s EV sector toward higher-quality, explosion-proof batteries.

With recent EV fire incidents making headlines, this move signals China’s zero-tolerance stance on battery hazards. For consumers, it’s a win; for the industry, a game-changing challenge.
