It is most economical to charge vehicles between 01:00 and 07:00. The cost of charging an electric car depends mainly on two factors: the rate you have contracted and the capacity of the battery of your electric car.
In general, each kWh has an average price ranging between 0.06 € (night) and 0.15 € (day). Therefore, to calculate how much a full battery recharge would cost you, you must multiply the price of each kWh by the number of kWh your battery has.
