Title: Temperature adjustment device of battery
Inventor: TAKEUCHI TOMOYASU
IPC: H01M10/625
Filed: 2008-01-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a temperature adjustment device of a battery which can detect the temperature of an electrode body without carrying out complicated correction, and can adjust the temperature of the battery based on the detected result.  <P>SOLUTION: The temperature adjustment device 1 is constituted of a blower 11, a temperature sensor 12, and a temperature control unit 13. The temperature sensor 12 detects temperature of a case 103 that is not cooled by a refrigerant. A positive electrode terminal 101, a negative electrode terminal 102, and the case 103 are thermally insulated. For that reason, even if the positive electrode terminal 101 and the negative electrode terminal 102 are cooled by a refrigerant through refrigerators 101c, 102c, temperature of the battery 10 can be detected accurately without receiving the effect. Accordingly, it is not necessary to make complicated correction against a detected result differently as a conventional one. By this, since the temperature control device 13 controls circulation amount of the refrigerant via the blower 11 based on this accurate detected result, the temperature of the battery 10 can be adjusted appropriately.  <P>COPYRIGHT: (C)2009,JPO&INPIT
