<P>PROBLEM TO BE SOLVED: To suppress the energy consumption of a battery temperature control device. <P>SOLUTION: Cooling air is circulated while making a circulation path composed of a battery case 3 and a reflux duct 6 as a closed circuit. A cooling capacity needed for a cooler 4 may be equivalent to a calorific value in the battery 2. Therefore, while suppressing an increase in energy consumption of a battery temperature device 1, the battery 2 can be cooled surely. Furthermore, in the case vehicle on outdoor air temperature is lower than an air temperature after finishing heat exchange with the battery 2, the battery 2 is cooled by using vehicle outdoor air. <P>COPYRIGHT: (C)2004,JPO |
