What is Blade Battery?
BYD has been a pioneering name in the battery industry for more than 29 years. The driving force of each of our electric cars is the innovative BYD Blade Battery. Recognised as one of the world’s safest EV batteries, our battery has passed rigorous safety tests and is designed to maximise strength, range and life cycle.

01
Enhanced safety
The raw material, lithium iron phosphate 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.
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.
02
Optimised strength
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 optimised strength to the Blade Battery.
03
Longer range
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.
04
Longer lifecycle
Blade Battery has a long battery life with over 5000 charge and discharge cycles.

With a range of EV and PHEV to choose from, whether that’s fully electric or hybrid options, new energy vehicles give drivers the option to reduce their carbon footprint in a way that suits their lifestyle.
