Renault presented its vision of the car of the future full of technologies at the Vivatech show in Paris. And among these novelties is a new concept of batteries equipped with bidirectional chargers. Batteries of this type do not just store electricity to run the car. They can reserve their energy for other uses.
The principle is simple: charging takes place mainly when electricity production is plentiful, when wind turbines are running at full speed, when the sun is shining. In short, when electricity is cheap and supply often exceeds demand. Et une fois stockée, cette énergie peut ultérieurement être renvoyée dans le réseau électrique du domicile ou dans le réseau général pour être utilisée when la faiblit production parce qu’il n’y a pas de soleil, pas de vent ou que des centrales nucléaires sont in maintenance.
An electricity bill that could be cut in half
This dual-purpose battery offers at least three benefits. Elle est économique: si un automobiliste stocke de l’électricité when elle ne coûte pas grand-chose et qu’il l’utilise à titre personnel ou pour la resendre when elle vaut plus cher, l’effet sur la facture ne se fait pas wait. Renault ensures that it can be reduced by half with this type of battery. Above all because if we leave aside those for professional use, a car spends much more time parked than driving.
It is also more ecological. Indeed, the more such batteries the French car fleet has, the less of a problem the intermittent nature of wind and solar power will pose. These batteries are the best allies of renewable energies. Finally, this ability to become an electric “tap” can also be very practical when you are away from home. Renault plans to offer an optional 220V socket to connect any device anywhere.
First equipped model: the R5 marketed in 2024
The big question remains: will motorists accept that their battery is empty when they expect it to be full when they take the wheel? The designers of this battery system have thought about it. They have integrated a very simple command into the app to manage the car’s charge. All you have to do is indicate the time you plan to leave and the level of charge you will need and the system manages everything on its own to meet the needs of the motorist.
Last advantage of this innovation: it is not science fiction. These bidirectional batteries will be integrated into the future R5, the electric city car that Renault plans to market next year. As for the rest of the vehicles in the future electric range of the Diamond brand, logically they should follow. Knowing that there are already terminals to make any car battery bidirectional.
