Choosing the right type of home charging point
There are three types of electric vehicle ChargePoint: Slow, Fast and Rapid.
The fastest way to recharge your car. A rapid ChargePoint provides power at 43kW and typically takes around 30 minutes to charge a vehicle up to 80%. They are the most expensive to use, but not suitable for all vehicle types.
Fast ChargePoints offer speeds between 7kW and 22kW and are ideal when vehicles are parked for a few hours.
Slow ChargePoints provide power up to 3kW. They are the cheapest to use and most suitable when a vehicle is parked for a length of time such as overnight or when you’re at work.
The rate at which your vehicle can be charged is determined by the vehicle’s onboard charger which converts Alternating Current (AC) to Direct Current (DC). Details about your vehicle’s onboard charger can be found in your handbook or vehicle brochure.
Choosing the right connector
To be able to connect your electric vehicle to your ChargePoint you’ll need a cable fitted with connectors which match the outlet socket on the charger and the inlet socket on your car.
The type of connector used will depend on whether your electric vehicle is charged using Alternative Current (AC) or Direct Current (DC) and whether you choose a Rapid, Fast or Slow ChargePoint. Your car will come with a standard cable, but you will probably need to purchase another for use at off-site ChargePoints. These cost around £145.

The following table provides a summary of charging technology, connectors and their charging times:
|Power rating||3-7kW||7-22kW||up to 50kW|
|Electrical supply type||AC||Usually AC, DC available at higher rates||Usually DC, AC also available|
|Charge time||4 to 8 hours||2 to 4 hours||25-40 minutes (80% charge)|
|Vehicle range added in 15 minutes||3-6 miles||6-20 miles||35-40 miles|
|Connector||Type-1||Type-1 (max 7kW)|
|Best use||Home/work||Home/work/on-the-go||On-the-go/long journeys|
|EV compatibility||All||All, some vehicles may charge slower than others||Dependent on connector type. Not all BEVs and very few PHEVs are capable of accepting a rapid charge.|

Choosing the right ChargePoint cable:
Permanent or Removable?
The cable that connects your electric vehicle to the charging unit can be permanently attached to the ChargePoint (tethered) or removable (untethered). You can use both options at home but when you are using public charging points you may want to purchase a removable (untethered) cable in case a public ChargePoint doesn’t have a permanent cable.
How much does it cost to install a ChargePoint?
Installation costs including the ChargePoint range between £400 to £1000, depending on how powerful the charger is (i.e. rapid/fast/slow). To reduce the cost of a new ChargePoint, the Government is running the Electric Vehicle Homecharge Scheme.
Eligibility – If you are the registered keeper, or the primary user, of an eligible electric vehicle you could receive up to 75% (capped at £350, inc VAT) off the total cost of the ChargePoint and installation costs.
|Installation Costs including ChargePoint||£400 to £1000|
|75% funding from the Electric Vehicle Homecharge Scheme||£300 to £350|
|Actual cost||£100 to £650|
|Extra Connection cable approx.||£145|
