Question: how much does it cost to change an electric car?
Answer: The average electricity cost in the UK is around 14p per kilowatt-hour (kWh). So, using a 3kW charger to fuly top up a Nissan Leaf with a 40kWh battery would take 13.3 hours, at a cost of £5.76. With the Nissan's quoted range of 168 miles, that amounts to just over 3p per mile.
