BYD’s Blade Battery/Flash Charge Blade Battery Pass New National Standard Ahead of Schedule

This morning, Li Yunfei, general manager of BYD’s Public Relations Department, announced via social media that both BYD’s Blade Battery and Flash Charge Blade Battery have preemptively passed all items of the new battery national standard testing, obtaining certification from the China Automotive Technology and Research Center (CATARC).

In May 2025, with the formal implementation of MIIT’s Technical Requirements and Test Methods for Electric Vehicle Traction Battery Endurance (GB 38031-2025), the power battery industry will face the most stringent safety and technological thresholds in history.

Key Requirements of the New Standard:

1. Extreme Condition Testing

• Added 150J bottom impact test
• Post-fast-charge safety verification (short-circuit detection after 300 fast-charge cycles)
• Mandatory zero fire/explosion in scenarios including nail penetration, water immersion, and thermal runaway.

2. Lifespan & Performance Validation

• Battery health (SOCE) must remain ≥82% after 5 years/100,000 km
• Slow charging must demonstrate significantly lower lifespan degradation vs fast charging.

Technological Breakthroughs in BYD’s 2nd-Gen Flash Charge Blade Battery:

• 6C ultra-fast charging: 400 km range replenishment in 5 minutes
• Integrated with full-domain kilovolt high-voltage architecture, achieving 1 MW (1000kW) peak power
• Concave terminal design boosts energy density to 190 Wh/kg, enabling 1,000+ km range
• New electrolyte formula delivers 80% discharge capacity at -30°C, with cycle degradation rate below industry average
• Mass application expected in 2025 premium models (e.g., Yangwang U7)

Industry Shift:

2025 data shows LFP (lithium iron phosphate) batteries now dominate 72%+ of installations, signaling a strategic pivot from “energy density race” to “safety & longevity-first” rational development.

BYD’s dual technological advancements not only align with its safety-centric R&D philosophy but also accelerate China’s power battery industry transition from technology follower to global leader.
