BATTERY COOLING SYSTEM, VEHICLE, AND NON-TRANSITORY RECORDING MEDIUM

A battery cooling system includes: one or more processors; and one or more memories communicably coupled to the one or more processors. The one or more processors: execute a temperature acquisition process of acquiring a temperature of a battery mounted on a vehicle; execute an output control process of making a comparison of the temperature of the battery acquired by the temperature acquisition process with a predetermined threshold, and controlling, in accordance with a result of the comparison, a cooling capacity of a cooling fan configured to cool the battery; execute an open or closed state recognition process of recognizing an open or closed state of a window openable and closable and provided in the vehicle; and, in executing the output control process, use different thresholds as the predetermined threshold, depending on the open or closed state recognized by the open or closed state recognition process.
