A power cut backup system (1) comprises: a power source device (3) within a residence (2); and a vehicle (6) which can be connected with or isolated from the power source device (3) by way of a power cable (5). The power source device (3) transmits by way of the power cable (5) control information for controlling the vehicle (6) in the event of a power cut. The vehicle (6) supplies power for an accumulator (10) to the power source device (3) by way of the power cable (5) in accordance with the control information received, and reports to the power source device (3) information regarding the remaining charge of the accumulator (10). Furthermore, the power source device (3) supplies power from the accumulator (10) to each electrical appliance within the residence (2), for example, an electric light (2a), a television (2b), and an air conditioner (2c). A display device (9) displays information regarding the remaining charge of the accumulator (10).
