EV Charging Time Calculator

Estimate how long your electric car takes to charge. Enter the battery size, the charger power and the charge levels you want to go between. Remember that AC charging is also capped by your car’s onboard charger, and DC fast charging slows near full — so treat this as an indicative estimate.

Your car’s usable battery size (e.g. 25–60 kWh for most cars).

20% → 100% (24 kWh added) on a 7.4 kW charger.

AC charging note: the actual speed is also capped by your car’s onboard charger — a 22 kW charger only charges a 7 kW-onboard car at 7 kW. Most owners simply charge overnight at home.

Indicative only. This uses a simple energy ÷ power estimate with a typical efficiency and does not model your car’s onboard-charger limit, the DC taper near full, temperature, or battery state — real times vary. Home charger installation (a dedicated circuit, RCCB, earthing) must be by a licensed electrician.
