Abstract

Disclosed are a power source device and a vehicle having increased reliability as backup in the event of a power cut, even when the power of the vehicle is used during a power cut. A power source device (3) transmits by way of power cable (5) control information for controlling a 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 a residence (2). A display device (9) displays information regarding the remaining charge of the accumulator (10).
