Is Fast Charging Worth It? UK Study Finds Uncomfortable Answer

Frequent high‑power fast charging (over 100 kW) accelerates EV battery degradation, according to a Geotab study of 22,700 vehicles. Cars that used ultra‑fast charging for more than 12% of sessions saw about 2.5% annual degradation, versus ~1.5% with lighter use. Heat, battery chemistry, and extreme charge levels also contribute. Occasional fast charging is fine, but making it a habit speeds capacity loss.
