Abstract
A first voltage detection circuit is connected by first voltage detection lines to each node in a plurality of cells connected in series and detects the voltage of each of the plurality of cells. A second voltage detection circuit is connected, by second voltage detection lines, to each node in the plurality of cells and detects the voltage of each of the plurality of cells. First capacitance elements are each connected between two first voltage detection lines connected to each cell. Second capacitance elements are each connected between two second voltage detection lines connected to each cell. A first charge drawing circuit draws charge from each node in the plurality of cells, via each first voltage detection line. A second charge drawing circuit draws charge from each node in the plurality of cells, via each second voltage detection line.
