BYD's Blade battery, designed with blade-type cells to improve density and safety, has recorded 76 °C during ultra-fast charging tests. Although the value is within safe margins, it exceeds previous records and raises questions about long-term thermal management. This data concerns an industry seeking to compete with the most advanced LFP batteries.
Blade-type cells: promise and heating 🔥
The elongated cell structure allows for greater packing and structural strength, but ultra-fast charging raises the temperature to 76 °C. Under normal conditions, the system remains stable; however, accumulated heat could accelerate the chemical wear of the electrodes. BYD will need to optimize cooling or adjust charging profiles to prevent premature degradation in commercial fleets.
Fast charging: the Blade heats up more than a discussion forum 😅
It seems the Blade not only cuts the competition in density but also takes a break to sweat bullets. 76 degrees are nothing to panic about, but if you keep charging like this, the pack might ask for a towel and a fan. At least, when your car heats up, you can blame it on cutting-edge technology and not on forgetting to close the window.
