Title:
BATTERY TEMPERATURE REGULATING SYSTEM
Document Type and Number:
Japanese Patent JP2023180455
Kind Code:
A
Abstract:
To provide a battery temperature regulating system capable of suitably suppressing deterioration in the performance of each battery cell caused by temperature.SOLUTION: A battery temperature regulating system of the present invention comprises a compressor 1, a first heat exchanger 3, first to eleventh battery cells 5a to 5k, a second heat exchanger 7, a refrigerant passage 9, an expansion valve 15, a first on-off valve 17, a second on-off valve 19, and a control device 25. The second heat exchanger 7 can exchange heat between a refrigerant and the first to eleventh battery cells 5a to 5k. When there is a temperature adjustment request for reducing temperature variation among the first to eleventh battery cells 5a to 5k, the controller 25 switches the first on-off valves 17 to a first prohibition state to prohibit flowing of the refrigerant between the first heat exchanger 3 and the second heat exchanger 7, and switches the second on-off valve 19 to a second prohibition state to prohibit flowing of the refrigerant between the compressor 1 and the second heat exchanger 7.SELECTED DRAWING: Figure 4
