Cost To Charge Electric Car

Unfortunately working out the cost to charge an electric car can be quite complicated. The costs are dependant on the type of electric car you own, the size of the battery and the time of day you charge the car. Below we have listed the costs for charging your electric car at home, at work and at a public charging station. This should give you a good idea about the costs but bear in mind they are going to vary slightly depending on your personal circumstances.

HOW CAR CHARGING COSTS ARE CALCULATED

Theoretically if you are charging a BMW i3 with a 42.4kWh battery. Using a public charging station costs around 35p per kWH. So the cost is 42.4 x 35 = £14.77. If you are charging at home (which is a lot cheaper) it may cost 14p so the cost would be 42.4 x 14 = £5.90.

Cost To Charge Electric Car At Home

The cost for charging your electric car at home depends on 4 factors:

  1. The size of the battery you are charging
  2. How full it is when you start charging
  3. The kWh cost of your electricity
  4. The kWh of your charger

For this example if your battery 42.2 kWh is already 40% charged and you are charging it at night when electricity is cheapest the charge may cost 42.2 x 0.6 = 25.32 x 7 pence per kWh = £1.77 which is very reasonable if your car has a range of 200 miles.

CHARGING YOUR ELECTRIC CAR AT A PUBLIC CHARGING POINT

Charging your electric car at a public charging station car cost very different amounts. Zapmap have a great resource page detailing all of the major public charging networks. Many public locations offer free charging to their customers.

Public charging stations are usually rapid chargers (read more about the different types of chargers here). Public chargers vary in cost but a good guide is roughly £6 per 30 mins of charging which will usually give your car around 100 miles of range.

Tesla Supercharge Network has a large number of points across the UK and is free for Tesla owners.

COSTS TO CHARGE YOUR ELECTRIC CAR AT WORK

Some employers set up a free charging station at work while some opt for a pay to charge system. If there is no electric car charging point at your place of work speak to your employer because there are government grants available for up to £10,000 for 20 electric vehicle charging points (£350 per charging point).
