10% to 80% is the most useful 'fast charging' range — most EVs charge fastest below 80% and slow significantly above that. On a 75kW Rapid evyve charger, expect 25–45 minutes from 10% to 80% for a typical EV. On a 150kW Ultra-rapid, expect 15–30 minutes if your vehicle can accept that speed. Above 80%, charging slows dramatically — many drivers stop at 80% and resume their journey.
