BYD Blade Battery Achieves 5-Star Safety Milestone Globally
BYD's revolutionary Blade Battery technology passes stringent safety tests across 20+ countries, reinforcing its position as the safest EV battery available.
BYD’s Blade Battery technology has now achieved top safety ratings across 20+ countries, cementing its reputation as one of the safest EV battery designs in the industry.
The Nail Penetration Test
BYD’s most famous demonstration involves the nail penetration test—one of the most severe battery abuse tests:
| Battery Type | Result | Temperature |
|---|---|---|
| BYD Blade | No fire, no smoke | 30-60°C |
| NCM Ternary | Fire/explosion | 500°C+ |
| Standard LFP | Some smoke | 200-400°C |
The Blade Battery remained stable even when a steel nail was driven completely through the cells.
Why Blade Battery Is Different
Cell-to-Pack Design
Traditional battery packs have:
- Cells → Modules → Pack (3 layers)
Blade Battery has:
- Cells → Pack (2 layers)
This eliminates module housings, saving space and weight while improving safety.
LFP Chemistry
The Blade Battery uses Lithium Iron Phosphate (LFP):
- No thermal runaway - Won’t catch fire even if damaged
- Longer lifespan - 3,000+ charge cycles
- Cold-weather tolerant - Better performance in European winters
- No cobalt - More ethical, sustainable
Global Certifications
The Blade Battery has achieved:
- China: GB/T safety standards (5-star)
- Europe: UN ECE R100 certification
- USA: FMVSS 305 compliance
- Australia: ADR standards
- Europe: UN ECE R100 certification
Production Scale
BYD’s Blade Battery production has reached:
- 600+ GWh annual capacity by end of 2025
- 8 major factories in China
- 2 international plants (Hungary, Brazil)
What This Means for European Buyers
BYD vehicles available in Europe bring:
- Proven safety - Rigorous testing across multiple markets
- Winter reliability - LFP chemistry handles cold better than NMC
- Long lifespan - Batteries designed for 1M+ km service life
- Lower fire risk - Important for garage parking in European homes
