The future electric 5 – shown only in concept form so far – will be Renault‘s first car to come with a bidirectional on board charger, the automaker said.
Combined with a Mobilize (an EV focused group brand) Powerbox bidirectional charging station and the associated vehicle to grid (V2G) service, 5 owners will save on charging and reduce their overall electricity bill by selling power back to the grid, Renault added.

“In addition, according to the Mobilize electricity contract, power used to recharge EV batteries will be carbon neutral,” a statement said.
“[We see] electric vehicles becoming a source of energy for homes and the grid, providing additional flexibility, and making it easier to integrate renewable energies into the energy mix.”
V2G will also be available for future Renault electric vehicles.
“On average, the cost of charging is cut by half,” claimed Corinne Frasson, director of energy services, Mobilize.

By GlobalDataThe V2G bidirectional charging technology allows driver to put charging on hold during peak hours and to inject power back into the home, especially when electricity is expensive, and back to the grid when demand is high.
Charging takes place when electricity supply on the grid is high and therefore cheaper.
This V2G service is based on complementary components:
• Bidirectional on board charger incorporating V2G technology and the Mobilize Powerbox, a bidirectional terminal designed in collaboration with the Software République;
• Mobilize electricity contract, provided by The Mobility House, which guarantees carbon neutral electricity and monetises energy injected back into the grid through automated bidirectional charging management;
• Smartphone app used to program bidirectional charging, by setting the time when the vehicle is going to be used next and the desired battery level.
The new bidirectional charger uses innovative architecture to integrate hardware such as natively reversible electrotechnical components and electrical-current management software which will provide ongoing access to the V2G service while preserving battery capacity.
In addition to reinjecting electricity into the power grid, the bidirectional charger can also be used to power electrical appliances via an adapter for the vehicle’s charging socket which provides the same energy output as a European 220 volt domestic power outlet.
Developed by the Software République (Orange, Renault Group, STMicroelectronics, and Thales) and IoTecha, the Mobilize Powerbox terminal communicates with the car and the cloud to determine whether it should recharge the battery or send power back to the grid depending on battery charging needs, domestic needs, and incentives from the energy market and power grid.
It’s made at the Lacroix electronics assembly plant in Beaupréau-en-Mauges, western France, and power of the bidirectional terminal will range between 7kW and 22kW, depending on the power supply in each country, and it will be compatible with all electric and plug-in hybrid vehicles.
Mobilize will offer a competitively priced carbon-neutral electricity contract through The Mobility House.
The Mobility House has worked with Renault Group partner since 2018 on the Advanced Battery Storage system – a stationary device using electric vehicle batteries.
The Mobilize V2G service will be available from the launch of the Renault 5 in France and Germany in 2024, followed by the UK in 2025.
