<P>PROBLEM TO BE SOLVED: To provide a device for controlling the temperature of a battery mounted on a car to utilize energy effectively, and to provide the car equipped with it. <P>SOLUTION: Since the temperatures of an inverter 3 and a motor generator 2 become about 80°C at running, it is possible to utilize them as heat sources serving as heaters heating the battery 1. Thus, the motor generator 2 and the inverter 3 are respectively equipped with heat exchangers 12 and 13, by which heat is ejected via air flowing via a ventilation flue 26. When the temperature of the battery has become low at the start under an environment, such as winter time, where the temperature of open air is -20°C to 0°C, a ventilation course can be changed, as necessary, using valves 9, 10 and 11, in such a way that on the upstream side of the ventilation course is set in the heat exchangers 12 and 13 which are placed on the upstream, in relation to the battery 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
