EV charging time formula

An EV’s charging time depends on two major factors: how much charge (kWh) is needed, and how much power (kW) the EV charging station provides. Divide the charge needed by the power provided to get the estimated hours of charge time required.

Charge needed (kWh)
Charge power (kW)
=  Hours of charging time
Example

A Tesla Model 3 with an 80 kWh battery size parks at a 7.68 kW Level 2 charging station with 20% battery left. They would like to charge their EV to 80%.

Find charge needed in kWh:
80% – 20% = 60% needed
80 kWh (battery size) x 0.6 (charge needed) = 48 kWh needed

48 kWh
7.68 kW
=  ~6.25 hours of charging time
