Gard: Soon an electric car that recovers part of its energy


The V2g system, managed by EDF, can power your car and your home.

EDF has been working for over two years now on the development of V2g (Vehicle-to-grid), in other words a smart charging vehicle that can feed electricity back into the national grid.

To date, Occitania is the first test area in France. “The V2g principle allows the car to recover part of the electricity stored in its batteries to improve the operation of the electricity network”, explains Virginie Monnier-Mangue, regional director at EDF Occitanie and president of the Clean tech basin in Aramon.

With this system, the energy supplier sees the electric vehicle battery as an extension of the distribution network, a form of storage that it can draw on when needed.

So the battery becomes a source of energy that can be used for various needs of use “In the coming years, we will need more electricity and therefore more production methods than nuclear energy and renewable energy. Therefore, this system can to some extent correct this . lack and provide new energy solutions.” But then how does it work?

Not in a public space

You must first prepare yourself with the so-called V2g charging station
. In the morning, the driver charges his car with electricity and in the evening when he returns home he releases, thanks to his special station, what is left of the energy stored in his car’s battery to supply, if he wishes, the equipment of his car. house. In this way, the battery can be used as a charging station or as an electrical storage. “In this way, an individual can choose the right time to charge his battery, especially at night when electricity is cheap, or use stored electricity when energy prices are high.

But currently some pitfalls are emerging around this system. First of all, V2g stations are not placed in public space. “This system today only concerns the vehicle groups of communities and companies”, notes Virginie Monnier-Mangue who remembers that the Region of Occitanie helps financially for the purchase of these stations.

Limited transfer
Then, the V2g is only compatible with the range of small electric cars from the Nissan brand. “We are currently working with other brands, particularly Renault, to ensure that the development of this system is as comprehensive as possible.”
At the same time, EDF guarantees that the large distribution in France of V2g will take place in 2024, and that if everything goes well, together with light vehicles, “buses and trucks will be able to benefit from this technological revolution in the service of the energy transition” .

These two-way chargers are being developed by Dreev, a joint venture between EDF and California startup NUVVE.

“Participating in the energy transition!” The D & S Group with its 360 employees spread across France was, in Gard, one of the very first companies to choose to install a V2g terminal. “It has been three years since we chose to participate in this pilot project for a Nissan utility vehicle that works according to this principle, and we are very satisfied with this choice”, assures Julien Feja, president of the group based in Bagnols-sur-. Ceze.. The manager sees in him especially “the interest of participating in the energy transition without this affecting the operation of the company” specialized in preventing risks in the nuclear sector. In terms of operation, “the electricity of the car that is not used is sold to EDF which, every year, in return pays us several hundred euros, explains Julien Feja. In addition, the company has three-phase equipment that allows, in the evening, a very fast unloading time car.”
