BYD Tests Yangwang U7 Ultra‑Fast Charging 350 Times to Gauge Battery Health

BYD has subjected the Yangwang U7 to 350 ultra‑fast charging cycles over nine days to evaluate the impact on its battery. The vehicle can raise its charge from 10 % to 97 % in just nine minutes, a rate that pushes battery limits. The company’s study aims to determine whether such rapid charging causes accelerated degradation or other health issues in the battery pack. InsideEVs reports that the results will shed light on how extreme charging speeds affect long‑term battery performance. The findings are expected to inform future design choices and charging protocols for high‑power electric vehicles.
