A charge-discharge control device, characterized by comprising: a power storage device connected to an output side of a power converter; a first discharger, electrically connected to the power storage device, to discharge the power storage device, wherein the first discharger is an auxiliary power source to convert and supply input power to a load device and output a stop signal when an amount of power supplied to the load device is outside a prescribed range; a second discharger, electrically connected to the power storage device, to discharge the power storage device; a controller to charge and discharge the power storage device by controlling an output current of the power converter; and a determiner to determine whether an amount of power discharged via the first discharger satisfies a criterion, wherein the determiner determines that the amount of power discharged via the first discharger does not satisfy the criterion when output of the stop signal by the auxiliary power source is detected by the determiner; wherein when the controller acquires no warming-up operation command, the controller charges the power storage device; when the controller acquires the warming-up operation command, the controller performs a warming-up operation by repeated alternatingly charging the power storage device and discharging the power storage device via the first discharger; and when the controller acquires the warming-up operation command and the determiner determines that the amount of power discharged via the first discharger does not satisfy the criterion during the warming-up operation, the controller performs the warming-up operation by repeated alternatingly charging the power storage device and discharging the power storage device via the second discharger. a power storage device connected to an output side of a power converter; a first discharger, electrically connected to the power storage device, to discharge the power storage device, wherein the first discharger is an auxiliary power source to convert and supply input power to a load device and output a stop signal when an amount of power supplied to the load device is outside a prescribed range; a second discharger, electrically connected to the power storage device, to discharge the power storage device; a controller to charge and discharge the power storage device by controlling an output current of the power converter; and a determiner to determine whether an amount of power discharged via the first discharger satisfies a criterion, wherein the determiner determines that the amount of power discharged via the first discharger does not satisfy the criterion when output of the stop signal by the auxiliary power source is detected by the determiner; wherein when the controller acquires no warming-up operation command, the controller charges the power storage device; when the controller acquires the warming-up operation command, the controller performs a warming-up operation by repeated alternatingly charging the power storage device and discharging the power storage device via the first discharger; and when the controller acquires the warming-up operation command and the determiner determines that the amount of power discharged via the first discharger does not satisfy the criterion during the warming-up operation, the controller performs the warming-up operation by repeated alternatingly charging the power storage device and discharging the power storage device via the second discharger.
