More and more of us are choosing electric vehicles. Then the question of recharging arises. Most of us opt for home charging. But how to navigate the jungle of proposed solutions? Futura and the EDF Pulse & You co-ideation platform take stock of the subject.

In the French automobile market, the share of electric vehicles is increasingly important. From 7% in 2020, it reached 15% in the first five months of this year 2023. At the same time, the number of charging points open to the public is exploding. In May 2023, France crossed the symbolic threshold of 100,000 charging stations. That’s an increase of almost 62% in one year.
What would the ideal charging solution for your electric vehicle be for you?
But in reality, the overwhelming majority of electric car owners charge at home. It is this observation which encouraged the EDF Pulse & You co-ideation platform to look into the issue. What would be the ideal home charging solution for your electric vehicle? How to have it installed, at what cost or with what features? More than 500 experiences have already been shared. Among which, a certain number of questions. So for those who have questions regarding the possibilities of charging their future electric car at home, here are some answers.
Did you know ?
Since 2016, the EDF Pulse & You co-ideation platform has set itself the objective of building the world of tomorrow around the experiences and reflections of the Pulseurs. Already more than 14,000 EDF project managers, start-ups and individuals have registered. They regularly speak on different subjects.
You can very simply join them to enrich their discussions. To do this, it is enough to create an account, post your ideas and vote for the best contributions. The bottom line is that there are always rewards in the campaign theme for the most creative Pulsers.
First, know that it is, on paper, entirely possible to recharge an electric vehicle at home by plugging it into a simple domestic outlet. Most manufacturers, in fact, provide a cable that allows you to do this. This still raises some security questions. Although it seems that the majority of homes have sufficiently powerful electrical installations, it is better to check – or have it checked by a professional – beforehand to avoid any damage. Another disadvantage – certain, this time – is the recharge time which can become interminable. Between 10 and 20 hours for cars equipped with batteries of less than 50 kWh and an 80% charge. Well over 30 hours for cars equipped with batteries of 70 kWh or more. However, if you are a small driver and only cover a few kilometers each day, recharging your electric car from a domestic socket may still be sufficient.
Solutions adapted to home charging of an electric car
The other solution is to reinforce a domestic socket which can then allow an electric car to be recharged a little more quickly. Overnight, for example, for cars equipped with batteries of less than 50 kWh. Between 20 and 30 hours for batteries of 70 kWh or more. This requires the intervention of a licensed electrician, but the time saved may be worth the cost.

The best solution still remains the installation of a charging station at home. A Wallbox, as the experts say. Even the least powerful ones can cut the charging time in half. The most powerful allow cars equipped with batteries of less than 50 kWh to be recharged in less than 2 hours and batteries of 70 kWh or more in less than 5 hours. The installation may require taking out a three-phase electricity subscription and installing a new meter with the intervention, of course, of a professional electrician. Better yet, from a certified Electric Vehicle Charging Infrastructure (IRVE) electrician. So it is better to reserve the use of a so-called accelerated charging station – meaning one with a power greater than 11 kW – for those who use their electric car intensively or for those who have chosen a powerful vehicle.
The other advantage is that Wallboxes can be programmed to only charge during off-peak times and stop automatically once charging is complete. Or to disappear when you use, at the same time as your electric car is plugged in, your oven and your washing machine. Enough to avoid any damage to your installation. And for the most worried among you, know that some home charging stations require the use of a badge to be unlocked. What to prevent “energy theft”.
The most advanced technology, called V2G — for vehicule-to-grid —, allows you to think of your electric car’s battery as an energy reserve for the home. This type of intelligent terminal makes it possible, for example, to charge the battery when renewable energies, solar and wind in particular, produce a lot of electricity. And to return, if necessary, this electricity to the network when demand increases. The first advantage is that if during the day, you have only used 20% of your charge made the previous night during off-peak hours, you will be able, by connecting your electric car in the evening, to take advantage of the remaining charge to power your house at a reduced rate. The other advantage, if you provide the network with a V2G battery, is that you will be paid by the operators. To do this, your electric car must still be compatible.
