It will take most electric cars around 3 to 6 hours to fully charge using a standard 7kW charger.
For electric cars that support advanced chargers, such as 350kW chargers, it can take as little as 15 minutes to reach a full charge.
Home car charging is much faster than using a domestic 3 pin plug socket. Most home EV chargers have a power output of around 7kW, which is enough to deliver fast charging, with roughly 15-30 miles of drive time per hour of charge.
The majority of UK homes have single-phase power supplies. This means that they are compatible with a maximum charging rate of 7.4kW.
Faster chargers, such as 22kW chargers, are only compatible with three-phase power supplies, which are normally only used in commercial properties.
How to check if you have a three-phase connection
It is very unlikely that your home will have a three-phase power supply. Although, if you wanted to check, simply take a look at your fuse box.
- If your fuse box has one 100 amp fuse, this means that your home is powered through a single phase connection.
- If there are three 100 amp fuses, this means your home is powered by a three phase connection.
Homes that do have a three-phase power supply are eligible for faster chargers. Power outputs from faster chargers usually range from 22kW and above.
