Controlled by EDF, the V2g system can power your car and home.
EDF has been working for more than two years to develop a V2g (Vehicle-to-Grid), in other words a smart charging vehicle that can bring electricity back to the grid.
So far, Occitania is the first test region in France. “The V2g principle allows the car to recover part of the electricity stored in its batteries to optimize the operation of the electric grid,” explains Virginie Meunier-Mango, Regional Director at EDF Occitanie and Head of Clean tech Valley at Aramon.
network extension
With this system, the electric vehicle battery power supply is an extension of the distribution network, a kind of reservoir from which it can draw when necessary.
Thus, the battery becomes an energy source that can be used to meet different consumption needs “In the coming years, we will need more electricity and therefore more means of production that go beyond nuclear and renewable energies. Thus, this system can partially address this lack of new energy solutions and provide them.” But how does it work?
Not in public
You must first equip yourself with what is called a V2g charging station
. In the morning the driver electrically charges his car and in the evening when he returns home he discharges its charge, thanks to his own station, the remaining energy stored in his car’s battery to supply him, if he wishes, with his car’s equipment. a house. In this way, the battery can be used either as a charging station or as an electricity backup. “This way, an individual can choose the right time to charge their battery, especially at night when electricity is cheapest, or use stored electricity when energy prices are at their highest.”
But for now, some pitfalls about this system are emerging. First of all, V2g terminals are not installed in public places. “Today this system concerns only the fleets of vehicles of communities and companies”, specifies Virginie Meunier-Mango who mentions that the Occitani region is financially assisting in the purchase of these stations.
Small displacements
Then, the V2g engine is only compatible with a range of Nissan brand small-displacement electric vehicles. “We are currently working with other brands, in particular Renault, to ensure that this system is developed as widely as possible.”
Meanwhile, the EDF guarantees that widespread deployment in France of V2g will occur in 2024, and that, if all goes well, in addition to light vehicles, “buses and heavy goods vehicles will be able to benefit from this technological revolution in the service of energy transition.”
These two-way charging operations were developed by Dreev, a joint venture between EDF and California startup NUVVE.
“Participate in the energy transformation!” The D & S group with 360 employees spread across France was, in Gard, one of the first companies to choose to install a V2g terminal. “It’s been three years since we chose to participate in this test project with a Nissan SUV operating on this principle, and we are very satisfied with this choice,” confirms Julien Vega, group president based in Bagnols-sur-Cez. The leader sees in this, in particular, “the interest in participating in the energy transition without affecting the work of the company” that specializes in preventing risks in the nuclear sector. In terms of operation, Julien Vega explains: “The unused car’s electricity is sold to EDF which in return pays us several hundred euros a year. In addition, the company is equipped with three phases which allow, in the evening, a very fast time to unload the car”.
