In the UK, the most commonly recommended power ratings for home charging units range from 3-7 kW. Single-phase (AC) electricity supplies are typical for most homes, and a 7 kW charger is within the capacity of such a system. However, there are homes with three-phase (AC) supply that can support more powerful chargers up to 22 kW. Regardless of the power rating, it’s crucial to ensure that the electrical fuse board can handle the additional load of a home charging station before installation, and this should be confirmed with the installer.
