EV charging time calculator

Estimate charging time from battery capacity, starting and target charge levels and effective power. Compare scenarios with clear assumptions.

Enter charging requirements, losses and actual average input power. Example: 60 kWh battery from 20% to 80%, 10% losses, average 7.4 kW = about 5.41 hours.

How to use it

Enter charging requirements, losses and actual average input power. Example: 60 kWh battery from 20% to 80%, 10% losses, average 7.4 kW = about 5.41 hours.

Method and limits

Theoretical estimate with constant average input power and losses. Use actual average grid power; charger peak power is not the average.
