Electric Car Charging Costs

If you’re wondering how much does it cost to charge an electric car, we’ve written a complete guide explaining how much it costs to charge an electric car at home, in the workplace, or at public charging points in the UK.

What is the cost of charging an electric car?

We are going to break down the cost of charging an electric car at home, at your workplace, or at public charge points.

The average battery capacity in an electric car today is 40kwh, this size of battery can be found in the Nissan Leaf for example, the vehicle as claimed by Nissan can do around 168 miles on a full charge.

The equation to work out a full charge on your vehicle is simply:

The size of the EV’s battery pack x the electricity cost from your supplier (in pence per kwh)= the cost to charge your EV from empty to full.

So in our case, it would be 40 x 0.29584* = £11.83 cost to charge a Nissan Leaf.

What about the cost to charge a Tesla Model 3?

As they do a version with a 40kwh battery the costs would be the same.

*Based on British gas being £0.29584 at the time of writing.

Cost to charge an electric car at home

The average cost of charging your electric car from empty based on a 40kwh battery would be roughly £12. When compared to an alternative petrol engine vehicle e.g. the Nissan Micra with a 41 litre tank 41 x 1.7284** = £70.86. As you can see the savings are huge. However, you do need to take into account that at home charging will need to be done overnight as it can take up to 5 hours or more. But if you’re able to switch to a cheaper electric vehicle specific charging rate from your energy provider then the potential savings could be bigger. Bear in mind there won’t be many instances where you will need to charge your electric car from empty at home.

See our range of home chargers from 7kw up to 22kw.

Cost to charge at work

The cost of charging your electric car at work can vary by organisation. However, more and more workplaces are offering free charging as a staff perk or incentive to get more employees to switch to electric vehicles. You should speak to your workplace to see what benefits you could get.

Cost to charge an electric car at public charge points

While you’re out and about you will more than likely need to use public charge points at some point. Charges for these can vary widely from place to place and by region. Lots of supermarkets are offering free charging as an incentive for you to shop with them. Charge points that need to be paid for can usually be interacted with via an app, within the app you will find all the tariff details.

You can also download a few helpful apps to help you locate these charge points and see tariff pricing before you get there. Project EV for iPhone, Project EV Pro for iPhone, Zap-Map for iPhone, Project EV for Android, Project EV Pro for Android, Zap-Map for Android.

Rapid car charger cost

When you’re in a hurry to charge your electric car you can use rapid chargers, typically these charge a vehicle to around 90 miles in 30 minutes. However, these are usually the most expensive way of charging. We have a rapid charger here at R-EV Power that is open for public use. Charging a 40kwh battery on this charger would be 40 x 0.35*** = £14 with a connection fee of £0.95. As you can see this is more expensive, however, given the time taken this can really help if you’re in a hurry.
