摘要：PROBLEM TO BE SOLVED: To prevent abnormal temperature rising of a battery by accurately detecting a fault of a cooling fan and effectively use for a long time without decreasing battery performance. SOLUTION: A power source device with a battery is equipped with a rechargeable battery 1, a case 4 housing the battery 1, the cooling fan 3 cooling the battery 1 by forcibly sending air to the case 4, a battery temperature sensor 5 detecting temperature of the battery 1, a control circuit 2 controlling the operation of the cooling fan 3 with the temperature sensor 5, an inflow side temperature sensor 6 detecting air temperature on the inflow side flowing into the case 4 in which the battery 1 is housed in the outside of the case 4, and an exhausting side temperature sensor 7 detecting air temperature on the exhausting side exhausted from the case 4 after cooling the battery. The power source device decides the cooling fan 3 as the fault when the control circuit 2 detects the temperature difference of the detected temperatures of the exhaust side temperature sensor 7 and the inflow side temperature sensor 6, and this temperature difference is smaller than the set temperature.
