Abstract
In a vehicle, a power storage device starts to be charged at a set time. An electric power control unit monitors a charging/discharging device from startup of the charging/discharging device to the moment when charging starts. When the electric power control unit detects a problem in the charging/discharging device, a signal is sent to a timer control unit in order to cancel setting of the charging start time. When receiving the signal, the timer control unit cancels the setting. Specifically, even when the present time reaches the charging start time, the timer control unit does not transmits a signal for canceling the setting of the charging start time, i.e., a start instruction to the electric power control unit. The electric power control unit never allows operation of the charging/discharging device to start unless it receives the signal, so the charging/discharging device remains stopped.
