Provided is a storage battery cooling system capable of rapidly cooling a storage battery while suppressing heating of the storage battery. The battery cooling system includes a cooling fan that sucks air in a vehicle interior into an intake passage and conveys the air to a battery; and a control unit that controls the cooling fan on the basis of the intake air temperature and the battery temperature detected by the intake air temperature sensor and the battery temperature sensor. The control unit performs a temperature inspection operation for stopping the cooling fan and calculating a difference value obtained by subtracting the battery temperature from the intake air temperature after the cooling fan is operated and the air is conveyed to the battery, and repeats the temperature inspection operation when the difference value is greater than zero, and the control unit performs the next temperature inspection operation in the second and subsequent temperature inspection operations, and under the conditions that the difference value is greater than zero, and the current difference value is smaller than the previous difference value.

    提供一种蓄电池冷却系统,能够一边抑制对蓄电池的加热一边迅速冷却蓄电池。蓄电池冷却系统具备:冷却扇,将车室内的空气抽入进气通道并输送至蓄电池;和控制部,基于进气温度传感器及蓄电池温度传感器检测到的进气温度及蓄电池温度控制冷却扇。控制部在使冷却扇工作而将空气输送至蓄电池之后,进行使冷却扇停止并计算从进气温度减去蓄电池温度得到的差值的温度检查动作,在差值大于零的情况下,重复所述温度检查动作,所述控制部在第二次以后的所述温度检查动作中,在差值大于零且本次的差值小于前一次的差值的情况下,进行下一次的所述温度检查动作。
