BYD, a global leader in electric vehicles, has developed the Blade Battery, a breakthrough in EV battery technology. Designed with safety, strength, and efficiency in mind, the Blade Battery is already being used in many of BYD’s electric and hybrid cars. It offers peace of mind to drivers while also improving vehicle performance and lifespan.
One key highlight is that it passed the nail penetration test — one of the toughest battery safety tests in the industry. This test simulates a serious car accident where a sharp metal object pierces the battery, causing an internal short circuit. Even under these extreme conditions, the Blade Battery did not catch fire or release smoke, and its surface temperature stayed low, between 30°C to 60°C.
Key Features of the BYD Blade Battery
- Enhanced safety- The raw material, lithium iron phosphate, has several 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.
- 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 sides of the pack, greatly enhances the rigidity in vertical direction. It is this revolutionary design that gives optimised strength to the Blade Battery.
- 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.
- Longer lifecycle- Blade Battery has a long battery life with over 5000 charge and discharge cycles.
