V2H (Vehicle-to-Home)
Bidirectional technology that allows an EV battery to power a home during grid outages or for daily energy management, effectively using the car as a home battery.
Why It Matters
With 60-100 kWh batteries, EVs store 4-8× more energy than a typical home battery. V2H is available on the Ford F-150 Lightning and emerging for GM and Hyundai vehicles.
