As part of the European SCALE Project , and in partnership with Enedis , Clem’ has developed these past 9 months a Charging Point Operator (CPO) platform based on the OCPP 2.1 protocol. With the protocol only recently validated by the Open Charge Alliance ( OCA Alliance ) on January 25, 2025, Clem’ successfully demonstrated on April 10, 2025, that its V2G (Vehicle-to-Grid) platform is fully operational and compliant to serve municipalities and companies.
The use case presented involves both charging and discharging operations, managed from Clem’s end-user interface, relayed through the Clem OCPP2.1 server, and connected to a 7kW AC V2G charger provided by Institut VEDECOM.
The demonstration was conducted collaboratively with teams from Enedis, EDF, Vedecom, Ampere , and Clem’, marking a significant milestone in Europe: the first successful interoperability test between a CPO platform provider, a V2G charger manufacturer, and a V2G-capable electric vehicle OEM—all from different entities.
🔋A Renault R5 was used to perform V2G operations via the Vedecom charger, orchestrated by the clem.mobi V2G platform:
⚡V2H (Vehicle-to-Home): Energy was discharged from the R5 to power a building during a consumption peak.
⚡V2L (Vehicle-to-Load): The R5 discharged to recharge a Peugeot e208.
⚡Bidirectional building interactions: charging and discharging events were synchronized with real-time solar production from the building’s photovoltaic system.
This demonstrator highlights the strategic value of smart charging (#V1G and #V2G) to maximize both individual and collective self-consumption, as opposed to injecting excess power back into the grid—a practice that has become economically unviable due to the significant drop in feed-in tariffs since March 2025.
Throughout the day, all partners collected data, recorded performance curves, and analyzed results. The demonstration concluded with a group photo featuring experts in e-mobility and smart charging technologies, celebrating a major step forward in intelligent energy integration.
Congratulations to all the partners and stakeholders involved in making this day a success!
