A large EV battery typically runs a home's essential circuits for several days; a house heated by a heat pump in January may use the same energy in less than a day.

A cord must never run from the car into a dryer or range outlet to feed the house. That is prohibited by the Electrical Code, which requires transfer equipment between a standby source and the premises wiring (NEC 702.5), and it is dangerous to utility workers.","Vehicle-to-home (V2H): the car powers selected circuits or the whole house during an outage while a transfer switch, gateway or home hub disconnects the house from the grid.","Vehicle-to-grid (V2G): the car exports power to the grid while connected to it.

Most V2H systems deliver about 10 to 11.5 kW continuously, and a central air conditioner, a well pump, a heat pump and an electric range running together can exceed that.
