Title:
Group battery
Document Type and Number:
Japanese Patent JP6213203
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently dissipate heat of a rectifier and to attain reduction of cost.SOLUTION: In the case where one of a plurality of battery cells 12 is down and current flows to a rectifier 18 of the battery cell 12, a main body 1802 generates heat. In the case where the rectifier 18 overlaps a detection substrate 16, the heat generated from the main body 1802 is conducted from a heat sink 1802B to a cathode terminal 22A via a screw 2. The heat conducted to the cathode terminal 22A is dissipated in the cathode terminal 22A and efficiently dissipated into the battery cell 12 with high heat capacity. The heat conducted to the cathode terminal 22A is conducted to a bus bar 14 that is connected to the cathode terminal 22A and further, the heat conducted to the bus bar 14 is dissipated in the bus bar 14, transferred from the bus bar 14 to an anode terminal 22B of the other battery cell 12, dissipated in the anode terminal 22B and efficiently dissipated into the other battery cell 12.
