Vehicle-to-grid

Common card · No. 390963

Vehicle-to-grid (V2G) describes a system in which a battery electric vehicle (BEV) also can discharge its battery, thus acting in a bidirectional way, to power a local electrical load (Vehicle-to-load V2L). While a small power inverter plugged into the 12 Volt system of an automobile is usually limited to 120 Watt, many modern BEV offer AC power sockets that can deliver up to 3600 W to any device, like a Coffeemaker, or even to another electric car (vehicle-to-vehicle V2V), or "off-grid" even to a whole house (vehicle-to-house V2H ). In these simple concepts, the AC phase is generated standalone, with supposedly 50 Hz or 60 Hz, 230 Volt or 115 Volt, and is not synchronised with the local electrical grid as fully-fledged V2G to the grid requires more advanced equipment, processes, permissions, financial transactions. The term Vehicle-to-everything (V2X) is also used for communication of any vehicle. In case of energy transfer, the vehicle also might be a plug-in electric vehicle (PEV or...
