FAQ
How long does it take to charge an electric car at home?
Charging an electric car at home takes 12 to 26 hours from a normal 2.3 kW socket, depending on the battery. With a 7.4 kW wallbox, a 60 kWh battery goes from 20 to 80 % in about 5 hours, and with an 11 kW three-phase charger in about 3.5 hours. Most people simply charge overnight.
How long it takes to charge an EV at home by charger power
| How you charge | Power | Guide time |
|---|---|---|
| Normal socket with the car cable (mode 2) | 2.3 kW | 12 to 26 hours depending on battery |
| Dedicated socket or basic wallbox | 3.7 kW | about 15 hours for a 60 kWh battery |
| Single-phase wallbox | 7.4 kW | about 5 hours from 20 to 80 % on 60 kWh |
| Three-phase wallbox | 11 kW | about 3.5 hours from 20 to 80 % on 60 kWh |
How to work out yours
The sum is simple: energy you need (kWh) ÷ charging power (kW) = hours, then add 10 % for losses.
Example: a 60 kWh battery from 20 to 80 % needs 36 kWh. At 7.4 kW that is about 4.9 hours, which with losses comes to around 5 hours.
The battery is measured in kWh, which is energy; the charger in kW, which is power. Mix up the two units and the numbers will not add up.
What changes the time
- The car’s own on-board charger. On AC charging, the charger built into the vehicle sets the limit: if it accepts 7.4 kW, an 11 kW wallbox will not make it go faster.
- Dynamic load balancing. If the house is using a lot, the charger lowers its power so you do not exceed your contracted power, and it takes longer.
- The charge window. Day to day it is best to keep the battery between 20 and 80 % and charge to 100 % only before a long trip.
What you really need each day
You rarely charge a full battery. If you drive 40 km a day in a car that uses 17 kWh per 100 km, you need about 7 kWh: at 7.4 kW, around one hour of charging. Even at 3.7 kW it fits easily into one night. That is why a 7.4 kW wallbox suits almost every driver.
Slow charging and the battery
Charging at home, on alternating current (AC), is the gentlest way to treat the battery. Daily rapid charging on direct current (DC) is what degrades it most.
