2019 Renault Vehicle-to-grid

Renault is researching the feasibility of large-scale vehicle-to-grid (V2G) charging, with a pilot scheme beginning in Portugal and the Netherlands today.

V2G charging lets drivers sell their cars' battery power back to the grid at times of high electricity demand, with charging speeds increasing or decreasing automatically depending on supply.

One of Renault’s main objectives is to assess an “onboard reversible charger” solution, which would allow V2G charging to take place with only low-cost adaptations needed to existing charging terminals.

It also hopes to measure the large-scale feasibility of the technology, and demonstrate its value to local and national grid operators.

V2G charging could encourage the uptake of wind and solar power, as it would increase the total energy storage capacity available to suppliers.
