BYD has been a pioneering name in the battery industry for more than 27 years. Our latest game-changing Blade Battery has passed a series of extreme tests in rigorous conditions making it one of the world’s safest batteries.
The raw material, lithium iron phosphate (LFP) has a number of beneficial characteristics: slow heat generation, low heat release and non oxygen release. The unique flat rectangle shape also improves cooling efficiency and preheating performance.
Blade Battery has safely passed the nail penetration test without emitting fire or smoke.
Arranged in an array in one pack, each cell serves as a structural beam to help withstand the force. The aluminum honeycomb-like structure, with high-strength panels on upper and lower side of the pack, greatly enhances the rigidity in vertical direction.
It is this revolutionary design that gives optimized strength to the Blade Battery.
The space utilisation of the Blade Battery has been increased by over 50% compared with the traditional battery packs, which provides enhanced energy density and delivers longer range.
Blade Battery has a long battery life with over 5000 charge and discharge cycles.
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.
