Vehicle-to-grid

Also called: V2G Vehicle-to-grid, or V2G, allows a compatible EV and bidirectional charging system to export electrical energy back towards the public electricity network. It can turn parked vehicles into controllable energy resources when the vehicle owner and system operator permit it. V2G can support services such as demand shifting, aggregation or grid balancing, depending on market rules. ISO 15118-20 supplies the vehicle-to-EVSE communication needed for modern bidirectional power-transfer control. In Great Britain, exporting equipment can also bring G99 connection requirements and G100 export limitation into scope. V2G is therefore a grid-connection project as well as a charger feature.
