Abstract
A plurality of cascade-connected voltage detection ICs detect each voltage of a plurality of battery cells connected in series and constituting an assembled battery, through a plurality of voltage detection lines. Power sources receive power from the assembled battery, for supplying power to the plurality of the voltage detection ICs. Communication lines connect between the plurality of the voltage detection ICs. A controlling circuit is connected to at least one of the plurality of the voltage detection ICs. First to third dummy resistors are connected to each of one or more of the voltage detection ICs which are not directly communicated to the controlling circuit out of the plurality of the voltage detection ICs. First to third switches turn on or off current supply through the first to third dummy resistors.
