How much does it cost in electricity to charge an electric car?

Every year there are more electric vehicle drivers. If you are developing charging solutions, it is sometimes difficult to estimate the price and choose the most advantageous mode.

Charging station quote! Free and without a contract!

While it is possible to charge your electric car at home, there are also free semi-private charging stations and classic, fast and ultra-fast public pay stations. Something to get lost in the face of an increasingly diversified offer! So how much does it cost to charge an electric car on electricity? Which device is ultimately the most advantageous? Our answers in this dossier.

How much does it cost in electricity to charge an electric car?

To charge your electric car, there are various devices such as charging stations (or Wallbox), reinforced electrical outlets and the use of a standard household socket. Therefore, filling your electric vehicle costs a certain price for its user, this price is calculated on the basis of the price per kilowatt hour (or kWh) of electricity.

However, evaluating the price of charging an electric vehicle is much more complex, because this calculation takes into account several parameters. On average, an electric car consumes 15 kWh / 100 km, but this figure is only a general average that can vary depending on the vehicle model, its battery, the type of trip made (city, country, road, etc.), the energy provider and the weather conditions encountered. Also, prices vary widely depending on the charging method chosen.

Charging your vehicle at home is very advantageous since the price is three to four times cheaper than charging a thermal vehicle. Of course, price variations are possible depending on the recharge time, that is, depending on peak and off-peak hours. From one energy supplier to another, there are significant variations in prices. But it is also possible to recharge your electric vehicle away from home, in public terminals, for a more attractive price than a full tank of traditional fuel, but generally more expensive than domestic recharging.

How much does it cost to charge your electric vehicle at home?

Charging at home is the most economical solution. To accurately calculate the cost of recharging an electric vehicle with electricity, it is necessary to take into account the consumption of the car (12, 15, 17 or 20 kWh / 100 km) and the price per kilowatt hour that can vary depending on the chosen power supplier. The rate applied will also depend on the recharging time, that is, in non-peak hours or in peak hours.

Below is an average estimate of the charge prices:

  • For an electric vehicle with a consumption of 12 kWh / 100 km, the cost of recharging for 100 km in a full hour varies between 1.75 euros and 2.30 euros, and between 1.40 euros and 1.50 euros.
  • For an electric vehicle with a consumption of 15 kWh / 100 km, the cost of recharging 100 km in a full hour varies between 2.20 euros and 2.90 euros, and between 1.70 euros and 1.90 euros in hours Valley.
  • For an electric vehicle with a consumption of 17 kWh / 100 km, the cost of recharging 100 km in a full hour varies between 2.50 euros and 3.30 euros, and between 2.00 euros and 2.20 euros in hours Valley.
  • For an electric vehicle with a consumption of 20 kWh / 100 km, the cost of recharging for 100 km in a full hour varies between € 2.90 and € 3.80, and between € 2.30 and € 2.50.

As you may have understood, charging an electric car at home costs between 1.40 euros and 3.80 euros per 100 km, which is much less than the 6 to 9 euros that a thermal vehicle costs. You can also cut costs by systematically scheduling electric vehicle recharges during off-peak periods.

How much does it cost to charge your electric vehicle outside the home?

It is possible to charge your vehicle outside your home completely free of charge. In fact, some shopping centers and store brands offer their customers free access to the charging stations in their car parks. Some companies offer identical services to their employees, sometimes with a financial contribution.

There are also public terminals accessible to any driver of an electric vehicle. However, most of these public terminals in France provide a payment based on the duration of the recharge with a count per minute or per hour or even through a flat rate subscription. However, it can also be billed per kilowatt hour consumed, allowing you to benefit from a better adjusted rate.

It is difficult to estimate the price of recharging in a public terminal, because prices vary a lot from one terminal to another since they depend on the type of terminal offered (conventional terminals are less expensive than fast and ultra-fast terminals. Fast), the operator of energy, the charging period and any subscription contracted. However, it is necessary to have a little more expensive than with a private terminal, to the extent that the operator generates a margin and that the price also allows financing the installation and maintenance work of the charging device. In any case, prices must always be clearly displayed to avoid unpleasant surprises.
