BYD Blade Battery

With over 28 years of innovation in battery technology, BYD continues to lead the industry with advanced electric mobility solutions. The revolutionary Blade Battery is engineered for exceptional safety and durability, successfully undergoing extensive testing under demanding conditions to deliver reliable performance and peace of mind on the road.

Enhanced Safety

The Blade Battery uses lithium iron phosphate as its core material, known for its strong thermal stability, producing heat slowly, releasing it at a lower rate, and not releasing oxygen during reactions. Its distinctive long, flat cell design also enhances both cooling efficiency and preheating performance. In safety testing, the Blade Battery has successfully withstood the nail penetration test without producing fire or smoke, highlighting its high level of safety and reliability in BYD battery technology.

Blade Battery Nail Penetration Test

The Blade Battery passed the industry's most extreme safety benchmark — the nail penetration test — without fire or explosion. A steel nail is driven through the cell, directly short-circuiting it. Conventional lithium-ion packs fail violently; the Blade Battery's LFP chemistry and blade-cell geometry remain stable, even at full charge.

No Fire on Puncture Nail penetration certified

Thermal Stability Surface temp ≤ 60 °C on short-circuit

Structural Cell-to-Pack Honeycomb crush resistance

Real-Time BMS Monitoring Millisecond fault detection

Blade Battery

Optimized Strength

Optimized for structural integrity, the cells are arranged in an array within the pack, where each cell functions like a structural beam to help absorb and distribute external forces. The aluminum honeycomb-inspired architecture, combined with high-strength panels on both the upper and lower sides of the pack, significantly improves vertical rigidity. This innovative design is what gives the Blade Battery its enhanced strength and durability within BYD battery systems.
