In a vehicle (100), a power storage device (4) starts to be charged at time set in advance. An electric power control unit (2) keeps on monitoring a charging/discharging device (30) during a period of time from a moment, at which startup of the charging/discharging device (30) at the charging start time has been set, to the moment at which the charging is started. When the electric power control unit (2) detects a problem in the charging/discharging device (30), the electric power control unit (2) sends a signal (S6) to a timer control unit (3) in order to cancel the setting of the charging start time. When receiving the signal (S6), the timer control unit (3) cancels the setting of the charging start time. Specifically, even when the present time reaches the charging start time, the timer control unit (3) does not transmits a signal (S3) for canceling the setting of the charging start time, i.e., a start instruction to the electric power control unit (2). The electric power control unit (2) never allows the operation of the charging/discharging device (30) to start unless it receives the signal (S3), so the charging/discharging device (30) remains stopped. |
