Less than you might think.
The consumption of an electric vehicle recharge is expressed in kWh and is charged directly to your bill (if you are recharging from home) or to your card (if you are recharging on the road).
Vehicles that have batteries with a higher current absorption capacity, have a longer range and obviously require more energy for a full recharge.
On average, however, the cars on the market have a battery pack between 30 and 50kWh, with real autonomy ranging between 200 and 400km with a recharge.
The price of recharging from home, therefore, follows the cost of your energy tariff while the price you pay to recharge from public access columns is on average € 0.50 per kWh.
