Charging Calculator
Estimate EV charging time.
Estimate charging time using charger capacity, the vehicle’s maximum charging rate, battery size, current state of charge, and target charge level.
Calculator
Estimate based on charger power, vehicle charging limit, battery size, and charge level.
The estimate uses the lower of the charger rating and the vehicle’s charging limit, then applies a simplified charging-curve adjustment at high state of charge.
Optional. Enter the vehicle’s published maximum AC or DC charging rate if you know it. If left blank, the calculator assumes the selected charger rating is the available limit.

Actual charging time depends on the vehicle’s charging curve, battery temperature, charger power sharing, site power availability, battery condition, and manufacturer controls. DC charging commonly slows above approximately 80% state of charge.
