Electric car: 4 tips so as not to explode your electricity bill

When you have the possibility of recharging at home, switching to the electric car allows you to save significant money compared to the cost of the pump of a thermal car. However, this energy transition is accompanied by an inevitable increase in consumption in electrons of the home. Here are some concrete levers to contain this increase and take full advantage of the economic advantages of the electric vehicle.

Opt for the right electricity contract

The transition to an electric car may require changing your electricity contract. In addition to reviewing the power of your meter, opting for a new type of contract can be judicious. A off -peak/off -peak hour offer makes it possible to greatly reduce your bill, provided you comply with the most advantageous schedules.

For example, for an average electric car covering 1000 km/month and recharged at 80 % of the time at home (approximately 150 kWh/month by including the losses of the on -board charger), the household electricity bill can increase by € 30.24/month (the KWh is billed 20.16 cents with the Blue Tariff offer and the Base Blue option). By opting for the off -peak hour option and recharging 80 % of the time during off -peak hours (16.96 cents per kWh) and 20 % during full hours (21.46 cents per kWh), the bill will only increase € 26.79/month.

Some electricity suppliers also offer offers dedicated to electric car drivers, sometimes with “super hollow” hours during which the KWH is even cheaper.

Plan your recharges

To take advantage of an electricity contract with the off -peak hour option, it is necessary to plan your refills. Most electric cars allow you to define a time slot during which recharge, from their central screen or their mobile app. This service sometimes requires a paying subscription.

By planning your recharge, it will be possible to recharge your electric vehicle only in off -peak hours. If we take up our previous example, the bill could go from € 26.79/month by recharging 80 % in off -peak hours at € 25.44/month by recharging 100 % in off -peak hours.

Opt for a smart recharge

It is still possible to go further to lighten your electricity bill. Thus, certain intelligent charging technologies allow an electric car to eat only during production peaks, in direct communication with the network. The best known technology is called V2G, to Vehicle-to-Gridbut it is not yet very widespread. It is a two -way recharging technology, where the car is capable of reinjecting energy into the network during consumption peaks, thus serving as a stationary storage system. The drivers agreeing to leave their electric car connected are thus remunerated, which allows them to partially compensate for the electricity bill of their vehicle. However, it is necessary to have a compatible car and wallbox, as Renault offers for some of its models, as well as a specific electricity contract.

By leaving your car plugged in 12 hours a day on a Wallbox V2G, the final cost of the recharge of an electric car would drop to only about € 5/month, by taking up the example previously used and according to the simulations provided by Renault and Mobilize.

Easier to set up, the unidirectional intelligent load, or Smart Chargingallows you to automatically load your car during energy production peaks, when electricity is the cheapest. Here, the car does not reinject this energy, but is content to load intelligently to limit its impact on the network. In a way, it is an evolution of hollow contract contracts, taking into account the state of the network in real time. This solution has the advantage of not requiring a two -way embedded charger, but still requires a specific Wallbox and electricity contract. The possible savings are not as important as in V2G and this solution is still not very widespread.

Finally, these technologies are even more interesting if you are equipped with photovoltaic panels. The electric car can thus be loaded as a priority with the energy they produce, limiting the consumption of the household with an electricity supplier.

Apply ecoconduite rules

Finally, a last lever reduces your electricity bill in all the aforementioned situations. Ecoconduite, aimed at limiting its energy consumption, will only increase possible savings, at home or during recharges on public terminals. It is therefore advisable to adopt a gentle driving and to be anticipated.

Heating and air conditioning are also large energy expenditure posts in electric cars. It is therefore preferable to prioritize the use of heated seats and steering wheel, if applicable. By applying certain ecocondumed rules, energy savings can easily reach 10 to 20 %.

In summary, the impact of an electric car on its electricity bill can considerably be reduced, strengthening the economic attraction of this energy. In the best conditions, these levers can reduce the impact of an electric car by around 90 % on its “painful”.
