制御装置
Document Type and Number:
Japanese Patent JP7295154
Kind Code:
B2
Abstract:
To provide a control unit capable of suppressing a variation in temperature of a plurality of secondary batteries in a secondary battery pack.SOLUTION: A control unit 40 according to an embodiment of the present invention calculates a temperature difference between a value based on the exhaust and intake temperatures of first multiple secondary batteries 10 and a value based on the exhaust and intake temperatures of second multiple secondary batteries 20. When a calculated temperature difference exceeds an upper limit, the control unit 40 increases the speed of rotation of a blower that cools multiple secondary batteries on a high temperature side, of a first blower 100 and a second blower 200. On the other hand, when a calculated temperature difference is less than a lower limit, the control unit 40 decreases the speed of rotation of a blower that cools multiple secondary batteries on a low temperature side, of the first blower 100 and the second blower 200.SELECTED DRAWING: Figure 3
