BYD’s second-gen Blade Battery sparks debate after reaching 169°F during ultra-fast charging

A real-world megawatt fast-charging test of a Fangchengbao Leopard 3 with BYD’s second-generation Blade Battery reportedly pushed cell temperature to about 169.6°F.

The result sparked debate over whether ultra-fast charging could accelerate battery wear, even as BYD touts durability and a lifetime cell warranty.

The case underscores a key EV tradeoff: faster charging improves convenience, but higher heat may increase stress on battery cells and thermal management systems.
