Using an EV as Backup Power
Yes, certain electric vehicles with bidirectional charging capability can power a home during a blackout. This is known as Vehicle-to-Home (V2H) and allows the EV’s battery to act as a backup energy source.
What You Need
- A compatible EV that supports V2H or V2X (Vehicle-to-Everything) technologies.
- A bidirectional home charger or energy management system capable of safely transferring power from the EV to your home’s electrical system.
- Professional installation and configuration, including transfer switches or isolation from the main grid to ensure safety.
How It Works
During a power outage, the system disconnects your home from the main grid and allows the EV to supply electricity to essential appliances or the entire home. The amount of power and duration depends on your EV’s battery size and household consumption.
Important Considerations
- Not all EVs or chargers support this feature — always check the specifications.
- Energy output may not cover all household needs; prioritizing critical loads (like lights, fridge, internet) is recommended.
- Some systems offer automatic switchover; others require manual activation.
