Japanese Patent JP5369127
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a battery system 100 capable of appropriately managing temperature.SOLUTION: There is provided a power system 100 in which a battery cell group 1A including a plurality of battery cells 1 and a detection circuit substrate 7 including a voltage detection circuit 21 configured to detect a voltage of each of the battery cells 1 are stored in housings 5e, 8, 9, 10. The housings 5e, 8, 9, 10 are separated into a cell group storage room and a substrate storage room 18 by separation walls 5a, 5b. The battery cell group 1A is arranged in the cell group storage room 17. The detection circuit substrate 7 is arranged in the substrate storage room 18. Cell room heat radiators 2, 3, which radiate heat generated in the battery cell group 1A to the outside of the cell group storage room 17, are provided in the cell group storage room 17. A substrate room heat radiator 19, which radiates heat generated in the detection circuit substrate 7 to the outside of the substrate storage room 18, is provided in the substrate storage room 18.
