The control unit is in a cooling state in which air inside the storage battery storage unit is sucked into the heat dissipation unit storage unit, and in a heating state in which air inside the heat dissipation unit storage unit is discharged into the storage battery storage unit And switch.

  In this power supply device, the air in the storage battery storage unit is sucked into the heat dissipation unit storage unit by being cooled by the control unit. Thereby, the air outside a housing | casing flows in into the inside of a storage battery storage part, and the temperature inside a storage battery storage part falls. Moreover, the air inside a heat radiating part storage part is discharged | emitted by the inside of a storage battery storage part by being made into a heating state by a control part. Thereby, the air warmed by the heat generated in the power conversion circuit flows into the storage battery storage unit, and the temperature inside the storage battery storage unit rises. As a result, the temperature of the storage battery can be adjusted with a simple configuration without providing a device such as a temperature adjustment device. Further, in this power supply device, the region in which the temperature of the air changes is formed by the heat radiating unit storage unit and the storage battery storage unit, and an air flow that can exchange heat energy between these regions is formed, and the conventional loss and The heat generated in the power conversion circuit that has been used is effectively used.

That is, when the second opening / closing part, the third opening / closing part, and the fifth opening / closing part are opened, and the first opening / closing part and the fourth opening / closing part are closed, the air inside the storage battery storage part is blown by the blower part. Is sucked into the heat radiating portion storage, and the air inside the heat radiating portion storage is discharged to the outside of the housing. At this time, the air outside the housing flows into the storage battery storage part via the second opening / closing part. In general, since the air outside the housing is colder than the air inside the storage battery storage unit, the temperature inside the storage battery storage unit decreases. In addition, when the first opening / closing part, the second opening / closing part, and the fourth opening / closing part are opened, and the third opening / closing part and the fifth opening / closing part are closed and the heating state is established, the air from the outside of the housing is caused by the air blowing part.

The air inside the unit storage unit is discharged to the outside of the housing. At this time, the outside of the housing is taken into the storage battery storage section through an opening / closing section for taking in and out air between the inside of the storage battery storage section and the outside of the housing. In general, since the air outside the housing is colder than the air inside the storage battery storage unit, the temperature inside the storage battery storage unit decreases. Moreover, if it is set as a heating state by rotating a ventilation part in the direction which sends air into the inside of a storage battery storage part, the air inside a thermal radiation part storage part will be sent into the inside of a storage battery storage part by a ventilation part. Since the air inside the heat radiating part storage part is the air heated by the heat generated in the power conversion circuit, the temperature inside the storage battery storage part rises.

Increase the temperature. That is, if the cooling state is achieved by rotating the first air blowing unit, the air inside the storage battery storage unit is sucked into the heat dissipation unit storage unit by the first air blowing unit, and the air inside the heat dissipation unit storage unit is It is discharged outside the housing. At this time, air outside the housing is taken into the storage battery storage portion via an opening / closing portion for taking air in and out between the inside of the storage battery storage portion and the outside of the housing. In general, since the air outside the housing is colder than the air inside the storage battery storage unit, the temperature inside the storage battery storage unit decreases. Moreover, if it is set as a heating state by rotating a 2nd ventilation part, the air inside a thermal radiation part storage part will be discharged | emitted by the 2nd ventilation part inside a storage battery storage part. Since the air inside the heat radiating part storage part is the air heated by the heat generated in the power conversion circuit, the temperature inside the storage battery storage part rises.

  In the power supply device of the present invention, the control unit controls the opening / closing amount of the sixth opening / closing unit for taking air in and out between the inside of the storage battery storage unit and the outside of the housing, thereby the storage battery storage unit in the heated state. You may adjust the temperature rise inside.
