It is often said, but in concrete terms, to what extent is the electric car cheaper than the thermal car ? What is the real cost of recharging an electric car when you benefit from improved installations at home ? Here, we go over everything you need to know about the cost of recharging an electric car, whether you use a standard domestic socket, a reinforced socket or a home charging station.

How much does it cost to charge an electric car via a standard domestic power outlet ?

Charging at home, using a standard domestic power outlet, will vary depending on the electricity contract but also the type of terminal installed. Estimates differ. According to Qovoltis, a full charge of an electric car costs between €2.50 and €3.50. According to EDF, to charge an electric car with a battery capacity of 50 kWh, it costs an average of €3.40. According to Engie, the cost of a full charge is estimated at between €1.34 and €3.70 (depending on peak/off-peak rates).

Note, however, that using a traditional household outlet to recharge your vehicle is not recommended, even if it is the least expensive solution. In fact, the charging time is longer, which drastically increases the risk of overheating or overvoltage, particularly due to the lack of power delivered by the domestic socket (2.3 kWh). It is therefore preferable to provide a special installation.

How to calculate a price estimate from your own electricity contract ?

You will have understood, it There are various different sources for determining the price of electricity for charging an electric car at home, but few agree precisely. The fairest thing is to make your own estimate which will really correspond to your consumption. Thus, determine the consumption of your vehicle (between 12 and 20 kWh per 100 kilometers) then multiply it by the cost per kWh of your electricity contract.

The difference is slight. In any case, it is up to you to carry out the calculation according to your vehicle and your electricity contract.

What installations should be planned to improve the home charging ?

Since the traditional domestic socket is not recommended, it is more judicious to use various solutions such as a reinforced socket or a home charging station.

The reinforced grip is more secure and efficient than the classic grip. It offers 3.2 kW power compared to 2.3 kW with a standard outlet. This greater power allows for 35% faster charging: for one night of charging, count on around 200 kilometers of autonomy. Furthermore, the reinforced socket is more secure since it is equipped with a differential circuit breaker to limit the risk of overheating within the electrical network.

Now there is the solution of home charging stations, also called wallboxes. These offer much higher charging power and also ensure maximum safety. Thus, the models of classic charging stations can range from a charge of 3.7 kW to 7.4 kW. There are also models reaching 11 or even 22 kW, but these are obviously more expensive. Note that with a power of 22 kW, you can recharge your vehicle (based on a 50 kW battery) in less than 2 h, while you will need count 7 h for a 7.4 kW station.

What is the cost of home installations ?

The reinforced socket is cheaper to purchase and install . The price of the shot is estimated between 130 and 230 euros. To this you will need to add the labor to carry out the installation: in total, count on around 500€ all taxes included to benefit with a power of 3.2 kW.

The charging station is more expensive, especially since it cannot be installed by yourself: you will have to go through a professional. The purchase price will depend on the model you choose: if you opt for a model offering 7.4 kW charging power, you should get away with 1000… € labor included. On the other hand, count almost double (€2000) as part of a terminal installation allowing 22 kW charging.

What assistance can I benefit from for installing a terminal at home ?

Since these installations can be expensive, it is entirely possible to benefit from various aids put in place for this purpose. Thus, in the case of installing a charging station, it is possible to benefit from a tax credit of €300 to provided that you have owned a primary residence for more than 2 years. On the other hand,VAT on such a product is reduced to 5.5%, which reduces the overall cost.

If you live in a condominium, you can try to take advantage of ADVENIR assistance, which allows you to finance 50% of the cost of the product and its installation ( with a ceiling of €600). It sometimes happens that certain communities offer special assistance to users who would like to install terminals (this is particularly the case in the city of Paris or in the Normandy region).
