Key takeaways
- Standard home chargers stop working during a grid outage.
- A generator or home battery can charge an EV only if the equipment is designed and installed for it.
- Some newer EVs can power your home (bidirectional charging) with special equipment.
What happens in an outage
Your charger needs grid power, so charging stops. A car that's already charged keeps its range, and keeping a buffer before storms is the simplest prep.

Backup power options
Home batteries and some generators can run a charger if the system is sized and wired for it. Talk to a licensed electrician; never backfeed a home with a generator without a proper transfer switch.
Your car as backup power
Some EVs support vehicle-to-home or vehicle-to-load, letting the car power appliances or the house through approved equipment. The DOE explains how bidirectional charging works.
