The purchase price of an electric car is higher than that of fuel cars, but the price of electricity per kilometer driven is lower than that of petrol or diesel. The more you drive, the cheaper it will be.
It is best to compare the cost price of cars on the basis of their Total Cost of Ownership (TCO): the total cost of the car calculated on its entire lifespan. The Total Cost of Ownership also takes into account insurance, taxes, resale value and running costs, such as tires, fuel and maintenance.
If you charge at home or at work, electricity is a lot cheaper than petrol and diesel. And those who have or charge solar panels during the off-peak rate drive even cheaper. In addition, an electric car requires less maintenance and you do not have to pay Tax on Registration (BIV) or Traffic Tax.
