V2G
V2G means vehicle-to-grid: the car can potentially send energy back to the electricity grid. It matters if you want the EV to do more than drive. Device power, home backup, grid export and automatic charger billing are separate capabilities with separate requirements.
How to compare it
It requires compatible hardware, tariffs, charger, grid rules and manufacturer support. The car alone is not enough.
- Identify the use case: devices, home, grid or charger authentication.
- Check output power and socket type.
- Confirm compatible external hardware.
What changes it
Bidirectional value changes with output power, socket type, inverter hardware, home equipment, tariffs, grid rules and manufacturer support.
- V2L powers devices; V2H powers a home through proper equipment.
- Output watts matter more than battery size for appliances.
- Grid export depends on local rules, not only the car.
Common trap
V2G availability is much more regional and conditional than ordinary charging.
- The car alone is not enough for home or grid export.
- Socket power can be much lower than the battery's stored energy suggests.
V2G: energy can leave the car
Vehicle energy can support devices, homes or the grid only when the surrounding hardware allows it.
