Document Type and Number:
WIPO Patent Application WO/2019/022072
Kind Code:
A1
Abstract:
A battery pack 100 which has cell units 146, 147 in which top-side and bottom-side battery cells are connected in series, and is capable of switching the connection state of the cell units 146, 147, wherein a control unit 350 monitors voltage imbalances between the plurality of cell units, and also monitors whether or not a cell unit contact failure has occurred. In order to stop charging/discharging when a contact failure occurs, a signal (abnormality stoppage signal 341 or charging stoppage signal 441) for stopping discharge is produced and outputted to the electrical device body-side.
