Claims6
A power conversion device comprising:
- an all-solid-state battery;
- a power converter that converts power between the all-solid-state battery and a load;
- and
- a thermal coupling member that thermally couples the all-solid-state battery and the power converter, the thermal coupling member being configured to transfer heat of the power converter to the all-solid-state battery, the thermal coupling member including a refrigerant flow channel through which a refrigerant circulates, wherein
- the all-solid-state battery is located at a downstream side of the refrigerant flow channel, and
- the power converter is located at an upstream side of the refrigerant flow channel.
