Title:
ASSEMBLED BATTERY
Document Type and Number:
WIPO Patent Application WO/2019/069971
Kind Code:
A1
Abstract:
Provided is a rechargeable assembled battery (1). The assembled battery is provided with: a plurality of battery cells (11-14); a detection unit (31); a plurality of discharge resistors (33); and a control unit (32). The battery cells are connected in series. The detection unit detects cell voltages (Vc1-Vc4) between the two ends of the battery cells. The discharge resistors are connected in parallel with the respective battery cells, and are capable of discharging the battery cells through short-circuiting. The control unit controls discharging of the battery cells on the basis of the cell voltages detected by the detection unit. The control unit changes, in accordance with the level of detected cell voltage, a resistance value of one or more of the discharge resistors for discharging the battery cell in which a cell voltage has been detected.
