This depends on where you will be charging your vehicle. Home recharging stations are the most economical in most situations.
The average electric vehicle uses 15 to 20 kWh per 100 km. If your home electricity rate is €0.25 and you drive an average of 15,000 km per year, your charging costs will range between €563 and €750 per year. When charging away from home, your rate is determined by the recharging terminal provider. A starting fee and incentive rate are often charged in addition to the kWh charge.
