BYD has been one of the pioneer in the battery industry for more than 26 year, our latest game-changing ultra-safe Blade Battery has passed serial extreme tests which made it now one of the world's safest batteries. Four distinct advantages of BYD's Blade Battery include a high starting temperature for exothermic reactions, slow heat release and low heat generation. Also, the space utilisation of the battery pack is increased by over 50% compared to the conventional Lithium Iron Phosphate block batteries. True innovation and an industrial first.
Nail penetration test
The nail penetration test is regarded as one of the most rigorous way to test the thermal runaway of batteries. The purpose is to simulate an internal short circuit of battery usually caused by external sharp metal objects penetrating the battery in a severe traffic accident.
While passing the nail penetration test, the Blade Battery did not emit smoke or fire after being penetrated, and its surface temperature only reached 30 to 60°C.
