Using an EV as Backup Power
Yes — if your EV supports V2H, it can supply electricity to your home during a blackout.
What You Need
- An EV with V2H or V2X capability.
- A bidirectional home charger or inverter system.
- Professional installation, including a transfer switch to disconnect from the grid for safety.
How It Works
When the grid goes down, the transfer switch isolates your home, allowing the EV battery to power essential loads or the whole house depending on its capacity and your energy needs.
Important Considerations
- Not all EVs or chargers support V2H.
- Backup capacity depends on your EV’s battery size and household consumption.
- Some systems switch automatically; others require manual activation.
