Definition & In-depth Analysis: V2H (Vehicle-to-Home) is a specific application of [V2X] technology where the EV’s battery serves as a backup power source for a residential property. In the event of a power outage or during hours when utility rates are at their highest, the car provides electricity to the house through a bidirectional charger.
A typical V2H system includes a bidirectional charging station and an automatic transfer switch (ATS) to isolate the home from the grid during an outage. This setup provides much higher capacity than standard home batteries (like the Powerwall), as most EVs have batteries ranging from 60kWh to 100kWh—enough to power a standard household for several days. It represents the ultimate in energy resilience and independence for homeowners.
Application Example: During a severe winter storm that causes a regional blackout, a homeowner uses their EV and a YD-EV V2H charger to keep their lights, refrigerator, and heating system running. For 48 hours, the car acts as a “silent generator,” providing comfort and safety for the family until the grid is restored.
