HOW MUCH DOES IT COST TO CHARGE MY ELECTRIC CAR AT HOME?

The cost of charging varies depending on your tariff (and, if on Economy 7, the time of day). An average electricity rate is 12p per kWh, meaning your car could cost as little as 2p per mile to run. Huge savings can be made on fuel – an estimated £1000 a year compared to petrol.

How the costs compare to fuel

We have used the example of two similarly sized cars, a Renault Clio Expression 1.2 and a Renault Zoe Expression Nav (the cheapest of each model). The ‘real-world’ range for the electric car is given, rather than the specified max. range at full efficiency.

Renault Zoe (Electric)Renault Clio (Petrol)

Tank/battery capacity 41kWh 45L
Cost per unit of fuel 12p £1.19
Total cost of charging/fuelling £4.92 £53.55
Range (miles) 186 504

 

We can supply various types and manufacturers of chargers to suit your needs here are some recommended samples:

WHICH CHARGER DO I NEED?

  • Mode
  • Type of plug
  • Rated power (KW)

The rated power is determined by the charge current (Amps) and the voltage.

The limiting factor in rated power is usually the grid connection - if you have a standard domestic single phase (230V) supply, you won't be able to achieve a charging rate of more than 7.4kW. Even with a standard commercial 3 phase connection, the power rating for AC charging is limited to 22kW.

The options for rated power are summarised in the following table. Note that most cars have a battery sized at between 10kWh and 40kWh (100 miles typically takes 30kWh plus).  Tesla models have a 75kWh to 100kWh battery.
