EV Charging

Most home EV chargers are around 7 kW, but the actual charging speed depends on your vehicle, charger and electrical supply.

For example, a vehicle capable of accepting 7 kW AC charging can make full use of a 7 kW home charger, while a vehicle with a lower AC charging limit will charge at its own maximum rate.

Charging time depends on your battery size, its remaining charge and the charging power your vehicle can accept. A full charge can take several hours, so overnight charging is often convenient. Smaller top-ups take less time, and you don’t need to wait until the battery is empty before plugging in.

Yes, with a suitable charger and electricity tariff. Smart charging can allow you to schedule your vehicle to charge during cheaper overnight or off-peak periods, potentially reducing charging costs.

Yes, with suitable compatible equipment. Some EV chargers can use surplus solar electricity to help charge your vehicle rather than exporting that electricity to the grid.

How much solar energy is available for charging will depend on your solar generation and how much electricity the property is using at the time.

Smart charging allows your charger to automatically control or schedule when your vehicle charges.

For example, you could plug your car in at 6pm but schedule charging to begin later when your electricity tariff becomes cheaper.

No. An EV charger works perfectly well using electricity from the grid. Solar PV and battery storage are optional technologies that can potentially be integrated with compatible chargers.

It depends on your parking arrangements and where the charging cable would need to run. The installation needs to provide a safe and suitable connection between the charger and the vehicle, without creating hazards across public footpaths or other areas.

EV chargers are commonly installed on an external wall, garage or suitable mounting post close to where the vehicle is parked.

The final position will depend on the property, parking location, cable route and electrical installation.

Not for a typical domestic charger. Most UK homes have a single-phase supply, which is commonly suitable for a 7 kW EV charger.

Higher-powered AC charging may require three-phase electricity, depending on the charger, vehicle and electrical supply available.

A correctly designed installation should take the property's electrical supply and existing demand into account.

Many modern chargers can also use load management, which can automatically reduce EV charging power when the property is using a lot of electricity elsewhere.

Load management allows an EV charger to adjust its charging power based on how much electricity the property is already using.

For example, if several high-powered appliances are operating at once, the charger can temporarily reduce its demand and increase it again when more electrical capacity becomes available.

Many smart EV chargers have an app that allows you to monitor charging, view charging history and set schedules. Features vary between manufacturers and charger models.

A tethered charger has its charging cable permanently attached, making it quick and convenient to plug into your vehicle.

An untethered charger has a socket instead, allowing you to connect and remove your own charging cable when required.

Yes. Plug-in hybrid electric vehicles (PHEVs) can use compatible home EV chargers just like fully electric vehicles, although they normally have smaller batteries.

Not necessarily. Most modern UK and European electric vehicles use a Type 2 connection for AC charging, but vehicle compatibility and charging capability should always be checked when selecting a charger.

EV chargers and vehicle charging connections are designed for outdoor use, including normal UK weather conditions, when correctly installed and used in accordance with the manufacturer's instructions.

Potentially, but many smart chargers provide access controls through an app, RFID card or other security features. The available options depend on the charger selected.

Depending on the installation and electrical supply, the local Distribution Network Operator (DNO) may need to be notified or an application may be required.

This is something that can be assessed as part of the installation process rather than something the homeowner needs to figure out alone.

Yes. An EV charger can often be added to a property with existing solar PV or battery storage. If you'd like the technologies to work together, equipment compatibility and the existing system should be considered when selecting the charger.
