MANAGEMENT DEVICE AND POWER SUPPLY DEVICE

WIPO Patent Application WO/2017/159219

A1

In order to provide a technology capable of detecting disconnection and capable of specifying the location of the disconnection, a first voltage detection circuit (35) is connected by first voltage detection lines (L11-L14) to each node in a plurality of cells (S1-S3) connected in series and detects the voltage of each of the plurality of cells. A second voltage detection circuit (36) is connected, by second voltage detection lines (L21-L24), to each node in the plurality of cells (S1-S3) and detects the voltage of each of the plurality of cells. First capacitance elements (C11-C13) are each connected between two first voltage detection lines connected to each cell. Second capacitance elements (C21-C23) are each connected between two second voltage detection lines connected to each cell. A first charge drawing circuit (37) draws charge from each node in the plurality of cells (S1-S3), via each first voltage detection line (L11-L14). A second charge drawing circuit (38) draws charge from each node in the plurality of cells (S1-S3), via each second voltage detection line (L21-L24).
