Headlines about EV fires make for dramatic news, but the reality is that electric vehicles are significantly safer than petrol cars. BYD's Blade Battery takes safety even further with lithium iron phosphate (LFP) chemistry that essentially eliminates the risk of thermal runaway—the chain reaction that causes battery fires.
Separating Myth from Fact
Studies consistently show EV fire rates are 0.01-0.03% vs. 1-2% for ICE vehicles. EVs are 20-60x less likely to catch fire than petrol cars.
Unlike NMC/NCA chemistries, LFP batteries don't release oxygen when damaged—the fundamental cause of battery fires is eliminated at the chemistry level.
The Nail Penetration Test
The most demanding battery safety test involves driving a steel nail through a fully charged cell at speed. This simulates the worst-case scenario of severe crash damage:
| Battery Type | Nail Test Result | Temperature |
|---|---|---|
| Traditional Ternary (NMC) | Violent fire, explosion | 500°C+ |
| Traditional LFP Block | Smoke, no open flame | 200-400°C |
| BYD Blade Battery | No smoke, no fire | 30-60°C |
Why the Blade Design Matters
The Blade's elongated cell design spreads heat over a larger surface area, preventing hot spots. Combined with LFP's inherent stability, the result is a battery that simply cannot catch fire under any reasonable abuse scenario.
Chemistry Comparison: LFP vs. NMC
Lithium Iron Phosphate (LFP)
- Thermal decomposition: 270°C—far above operating temperatures
- Oxygen release: None—no fuel for thermal runaway
- Fire risk: Essentially zero under normal and abuse conditions
Nickel Manganese Cobalt (NMC)
- Thermal decomposition: 210°C—closer to extreme operating conditions
- Oxygen release: Yes—provides fuel for self-sustaining fires
- Fire risk: Low but present, especially under damage conditions
Real-World Safety Record
Since the Blade Battery's introduction in 2020, there have been zero reported fires attributed to Blade Battery failure in BYD vehicles. With millions of Blade-equipped vehicles on the road globally, this track record validates the technology's safety claims.
