A 7kW EV charger gives your electric car about 25 to 30 miles of range for every hour it charges. This usually takes about 4 to 8 hours to fully charge the battery, depending on how empty it is. If you just need a quick boost, it can take around 4 hours. These chargers use 220-240 Volts AC and can provide up to 32 Amps (7kW).

If you have several electric cars in your home, a 22kW EV charger might be a good option for sharing. However, if you only have one electric car, a 7kW charger is usually enough.

Many EV drivers can’t use a 22kW charger because most homes in the UK have only a single-phase power supply, which only supports 7kW chargers. There are a few vehicles that can use the full 22kW power. A 22kW charger is three times faster than a 7kW charger and six times faster than a standard 3-pin plug charger, adding 37-50 miles of range each hour. It can fully charge an electric car in about 3-4 hours or take 1-2 hours for a quick top-up.

Inside an electric vehicle, there’s an on-board charger that changes AC power to DC power to charge the battery. A DC fast charger skips this step and charges the battery directly, making it much quicker. The main benefit of DC charging is that it works much faster than regular AC charging. This is great for long trips since it cuts down the time you need to spend charging.
