GoKawiilEV-to-home power requires bidirectional hardware most cars and chargers lack
Many EVs carry enough battery capacity to power a house, but doing so requires vehicle-to-home (V2H) compatibility, a bidirectional charger with a DC-to-AC inverter, and an islanding or transfer switch. Without that specific hardware, energy cannot flow backward from the car into the home, regardless of battery size. The report also distinguishes V2H from vehicle-to-load (V2L), which only powers individual devices rather than an entire household.
