Charge at Home / The basics
How long does it take to charge an EV at home?
Hours equal the miles you need divided by the miles each hour adds. The table does the division.
Charging time is a division: the miles of range you want back, divided by the miles each hour of charging adds. You rarely charge from empty, so start from the miles you actually drove.
| You drove | Level 1 (1.44 kW) | Level 2 (5.76 kW) | Level 2 (7.68 kW) | Level 2 (11.52 kW) |
|---|---|---|---|---|
| 20 miles | 4.7 h | 1.2 h | 0.9 h | 0.6 h |
| 40 miles | 9.5 h | 2.4 h | 1.8 h | 1.2 h |
| 80 miles | 18.9 h | 4.7 h | 3.6 h | 2.4 h |
| 150 miles | 35.5 h | 8.9 h | 6.7 h | 4.4 h |
Range figures assume a car that uses 30 kWh per 100 miles and loses 12 percent of the energy between the wall and the battery. Your car's figure is on its fueleconomy.gov label; the calculator takes yours.
Why the last part of a charge is slower
Charging slows as the battery nears full, so the final stretch takes longer than this arithmetic says. That is one reason many owners set a daily limit below 100 percent and charge to full only before a long trip; your car's manual says what its maker recommends.
The car can be the bottleneck
The power that reaches the battery is the lesser of what the wall supplies and what the car's onboard charger accepts. If your car accepts 7.2 kW, a 11.52 kW charger will not shorten the night. Check the onboard charger rating before you pay for a bigger circuit.
