BYD announced the launch of its new Blade Battery, which is designed to be safer than existing electric vehicle (EV) batteries, according to a company press release. Wang Chuanfu, BYD chairman and president, expects this new battery to redefine safety standards for the industry.
- BYD wants to move the focus from battery range to battery safety.
- The company’s new Blade Battery resisted fire during penetration testing.
- This could help ease the concerns of those who worry about the safety of electric vehicles.
The Blade Battery underwent extensive testing, including being crushed, bent, heated in a furnace to 300 degrees Celsius, and the nail penetration test, which evaluates thermal runaway. During the penetration test, there was no fire or smoke and the surface temperature ranged from just 30 to 60 degrees Celsius.

Reducing the risk of fire
A ternary lithium battery subjected to the penetration test reached temperatures of over 500 degrees Celsius and caught fire. A conventional lithium iron phosphate block battery emitted neither fire nor smoke, but still reached surface temperatures of 200 to 400 degrees Celsius. The Blade Battery, with its lower surface temperature when penetrated, makes it less likely to cause a fire in an EV when damaged.
BYD believes the race for increased battery range has led to a decreased focus on battery safety. It sees the Blade Battery as a way of making battery safety a larger piece of the development discussion. To that end, BYD isn’t keeping this technology all to itself. While it will debut on the BYD Han EV, set for launch this June, the company plans to share its knowledge with global partners to increase the safety of all EVs.
WHY THIS MATTERS
Electric vehicles still make up a very small percentage of vehicles on the road. Buyers voice numerous objections, from range to ease of charging, along with safety concerns. The introduction of battery technology that resists fire in the event of an accident removes one objection and could help increase overall acceptance of electric vehicles.
