Blade Battery

BYD has been a pioneering name in the battery industry for more than 29 years. Our latest innovation, the game-changing Blade Battery, is one of the world’s safest batteries, thanks to the rigorous tests it’s submitted to.

Enhanced safety

The BYD Blade Battery’s raw material - lithium iron phosphate - has a number of key beneficial characteristics: slow heat generation, low heat release and non oxygen release. The unique flat rectangle design also improves cooling efficiency and preheating performance. Also, the Blade Battery has safely passed the nail penetration test without emitting fire or smoke.

Nail penetration test

The nail penetration test is regarded as one of the most rigorous ways to test the thermal runaway of batteries. The purpose is to simulate an internal short-circuit of the battery. This is usually caused by external sharp metal objects penetrating the battery in a severe traffic accident. The Blade Battery passed the nail penetration test, without emitting smoke or fire. The surface temperature only reached 30 to 60°C.

Optimised strength

The revolutionary design of the Blade Battery is what gives it optimised strength. Arranged in an array in one pack, each cell serves as a structural beam. Its aluminium honeycomb structure, along with the high-strength panels on either sides of the pack, greatly enhance its vertical rigidity.

Longer range

The Blade Battery’s space utilisation is 50% greater than traditional battery packs. This provides enhanced energy density and delivers longer range.

Longer lifecycle

The Blade Battery has a long battery life with over 5000 charge and discharge cycles.
