Original Abstract Submitted
A battery cooling system includes a solid-state battery, a heat-exhausting device, a cooling circuit through which a refrigerant circulates between the solid-state battery and the heat-exhausting device, and a battery control device. The refrigerant absorbs heat from the solid-state battery. The heat-exhausting device exhausts heat absorbed from the solid-state battery. When a battery temperature of the solid-state battery exceeds an output limitation starting temperature, the battery control device controls an output current of the solid-state battery such that a heat generation amount of the solid-state battery, a heat absorption amount of the refrigerant from the solid-state battery, and a heat exhaust amount of the refrigerant in the heat-exhausting device are equal to each other, and controls the battery temperature such that the battery temperature is equal to or higher than the output limitation starting temperature, and is lower than an output permission upper-limit temperature of the solid-state battery.
