Electric vehicle running costs
If you have a fully electric vehicle (EV), its wheels are turned by one or more electric motors which are powered by a lithium-ion battery. When the battery gets low on charge, it needs to be recharged with electricity.
If you charge your EV with electricity on a typical day rate of 15p per kWh, you will make a big annual saving over petrol/diesel costs in your old vehicle.
However, if you charge your EV at a cheap, off-peak rate of say 5p per kWh, the cost of your annual electric miles will be three times less than at 15p per kWh.
You can see how electricity tariffs are the secret to ultra-low motoring costs that electric cars and vans can deliver.
