How much does it cost to recharge a car?

If, despite their increasing success, electric vehicles are still quite expensive to buy, they allow their owners to make considerable savings in terms of consumption and energy costs. The electricity cost of recharging an electric car for 100 km is in fact three to four times cheaper than the price to pay for the fuel needed for a petrol or diesel car.

The electricity cost of recharging a car at home lower than that caused by the fuel consumption of a thermal car

As its name suggests, an electric car runs on electricity, unlike thermal cars that run on gasoline or diesel. Most owners of electric cars choose to charge their vehicle at home, either by plugging it in, more precisely by connecting its battery to the electrical installation of the house, on a simple household socket, a so-called “reinforced” socket or a charging station also called wallbox. This last charging system is the most suitable because these terminals are powerful (from 7 kW to 22 kW) and allow a vehicle to be recharged in a minimum of time. In addition, the charging stations guarantee maximum safety.

Recharging your electric vehicle is also the most economical solution in terms of the cost of energy consumed. The price of “refueling” an electric car is calculated according to the price per kilowatt hour (kWh) charged by its electricity supplier. This cost may depend on when the vehicle is recharged, in particular whether the home has a peak hours/off-peak hours subscription, or not.

An electric car consumes an average of 15 kWh per 100 km, a consumption that can vary (between 12 and 20 kWh/100 km) depending on the type of journey made and the weather conditions. It is then estimated that the cost of recharging an electric vehicle with electricity is between 1.5 and 4 euros, compared to a cost of 6 to 9 euros for a petrol or diesel car. As indicated on the EDF website dedicated to private individuals, ” the price per kilometer of an electric car charged at home is around three to four times lower than that of a thermal vehicle ».

The elements to take into account to calculate the cost of recharging your vehicle with electricity

If an electric vehicle allows savings in terms of the cost of the energy used, the latter fluctuates according to many elements. In particular according to the type of electric car, and more specifically the power of its battery which determines the consumption of electricity, the tariffs applied by its energy supplier and the type of subscription taken out.

Indeed, the owner of an electric vehicle who benefits from a peak hours/off-peak hours subscription at his home for his electricity consumption will logically benefit from a lower bill if he takes advantage of off-peak hours (most often at night and /or on weekends) to charge their electric vehicle. It can thus save nearly 50% of the cost of electricity compared to the price of electricity during peak hours. For this purpose, many charge their car at night or choose to equip themselves with a so-called “intelligent” charging station, that is to say one whose switching on and off can be programmed remotely at the time of of his choice, especially at times when electricity is cheaper.

For information, EDF gives estimates of the cost of recharging electricity according to the level of consumption of different types of electric vehicles and the type of subscription:

  • for a car that consumes 12 kWh per 100 km, the cost of recharging electricity during a “peak hour” rate is 2.4 euros, in “off-peak hours” 1.4 euro;
  • for a car that consumes 15 kWh per 100 km, the cost of recharging electricity during a “peak hours” rate is 2.9 euros, in “off-peak hours” 1.8 euros;
  • for a car that consumes 17 kWh per 100 km, the cost of recharging electricity during a “peak hours” rate is 3.3 euros, in “off-peak hours” 2 euros;
  • for a car that consumes 20 kWh per 100 km, the cost of recharging electricity during a “peak hours” tariff is 3.9 euros, in “off-peak hours” 2.4 euros.
