## Abstract

A system includes: a power outage detector that detects a power outage, based on a voltage supplied by a commercial power supply; a charging device that is connected to the commercial power supply via the power outage detector and charges an electric vehicle; a residential distribution panel that is connected to the commercial power supply via the power outage detector and distributes power to a plurality of loads provided in a house; and a switch provided between the charging device and the residential distribution panel. When the power outage is detected, the switch is closed, and an AC voltage supplied from the electric vehicle is supplied to the residential distribution panel.

## Claims

### Claim 1

A system comprising:
a power outage detector that detects a power outage, based on a voltage supplied by a commercial power supply;
a charging device that is connected to the commercial power supply via the power outage detector and charges an electric vehicle;
a residential distribution panel that is connected to the commercial power supply via the power outage detector and distributes power to a plurality of loads provided in a house; and
a switch provided between the charging device and the residential distribution panel,
wherein when the power outage is detected, the switch is closed, and an AC voltage supplied from the electric vehicle is supplied to the residential distribution panel.

### Claim 2 (depends on 1)

The system according to claim 1,
wherein the residential distribution panel supplies the AC voltage to a predetermined load among the plurality of loads.

### Claim 3 (depends on 1)

The system according to claim 1, further comprising:
an other switch provided between the power outage detector and the charging device,
wherein the other switch is opened when the power outage is detected.

### Claim 4 (depends on 3)

The system according to claim 3,
wherein when the power outage detector detects a recovery from the power outage, the switch is opened and the other switch is closed.

### Claim 5

A method performed by a system that includes:
a power outage detector;
a charging device that is connected to a commercial power supply via the power outage detector and charges an electric vehicle;
a residential distribution panel that is connected to the commercial power supply via the power outage detector and distributes power to a plurality of loads provided in a house; and
a switch provided between the charging device and the residential distribution panel,
the method comprising:
detecting, by the power outage detector, a power outage, based on a voltage supplied by the commercial power supply; and
when the power outage is detected, closing the switch and supplying, to the residential distribution panel, an AC voltage supplied from the electric vehicle.
