## Key points

- An EV may power a home, but needs compatible bidirectional equipment.
- Installation can cost thousands and may require electrical upgrades.
- Check local support, vehicle compatibility and installation costs before buying.

## Summary

An electric vehicle can hold enough energy to run a home during an outage, but using it as a backup is more involved than plugging it into a socket. The car, charger and home equipment must support bidirectional power, and the system must safely disconnect the house from the grid.

Battery capacity affects how long power lasts, while output and appliance start-up surges determine what can run at once. Whole-home or selected-circuit backup may require a bidirectional charger, inverter, gateway, electrical upgrades and permits, costing thousands of dollars. Availability and compatibility vary by vehicle, model year and location; using the car also reduces its driving range and frequent use may add battery wear.
