E-PLATFORM 3.0 Blade Battery Like all BYD passenger cars offered in Europe, the BYD SEAL U is powered by the unique Blade Battery, which is revolutionary in several respects. BYD has been pioneering battery technology for over two decades and is firmly established as a market leader in this field. Its Blade Battery is born out of BYD’s relentless research and development, and considered as a major advancement for the EV industry. Optimised strength The Blade Battery was developed inhouse by BYD with the primary goal of optimising safety, durability, longevity, performance and space utilisation. The battery pack consists of many thin elon- gated cells that actually look like blades.
They are arranged neatly and evenly, with good temperature consistency and no heat accumulation. Arranged in an array in one pack, each cell serves as a structural beam to help withstand the force. The aluminium honeycomb-like structure, with high-strength panels on upper and lower side of the pack, greatly enhances the rigidity in vertical direction. Lithium iron phosphate The Blade Battery uses lithium iron phosphate (LFP) as a cathode material, which offers a higher level of safety and durability compared with conventional lithium-ion batteries. In addition, BYD’s Blade Battery is 100% free of cobalt, a material that raises ethical and environ- mental concerns in the mining industry.
LFP batteries are more resistant to extreme temperatures, without the risk of igniting or exploding. They have bet- ter thermal stability and are less sensi- tive to temperature fluctuations, while they can withstand more charge and dis- charge cycles with hardly any loss of capacity. This makes these batteries par- ticularly durable. 18
