A Welsh county council has installed a vehicle-to-grid (V2G) charger at its fleet depot that uses AC rather than DC current.
Denbighshire County Council has a fleet of more than 400 vehicles at its depot, of which more than 100 are electric vehicles (EVs) and can now make use of this AC charger.
The depot generates its own electricity from solar panels linked to a battery storage system as part of a smart local energy system.
V2G is bi-directional charging for an EV: power can be supplied from the grid to charge the EV, and it can also go from the EV back to the grid.
V2G allows an EV to be charged when electricity costs and the associated carbon emissions are low. It then allows electricity to be sent back to the grid, for example at times of peak demand – when an EV owner could get paid for providing this service.
V2G technology has been demonstrated through a number of lab tests and field trials.
In September 2024, with funding from the Department for Energy Security and Net Zero, the...
