PROBLEM TO BE SOLVED: To provide a battery cooling device capable of contributing to the reduction of energy consumption required for battery cooling by achieving efficient operation of a pump and a fan to maintain a battery temperature within a proper temperature range in a water cooling type battery cooling structure.SOLUTION: An ECU (30) acquires positional information of own vehicle and route information in a predetermined prediction range of vehicle front (S1). The ECU predicts temperature transition of a battery (11) (S2). When the predicted battery temperature exceeds a proper range (Yen is S3), the ECU calculates the necessary radiation amount from time until exceeding a proper temperature range and the maximum temperature difference exceeding the proper temperature range in a prediction range (S4, S5). The ECU selects the optimum operating point comprising the most efficient pump flow rate and fan flow rate for radiating this necessary radiation amount to operate a pump and a fan (S6-S10).SELECTED DRAWING: Figure 2 |
