This device comprises: a plurality of transit circuits, each constituted in such a manner that a single battery module can be installed therein, and constituting a path for a current transiting through the installed battery module; bypass circuits, each provided to correspond to each of the transit circuits, and constituting a path for a current that does not transit through the battery module installed in the corresponding transit circuit; circuit switching units, each provided for each of the transit circuits, and for switching between the transit circuit and the bypass circuit corresponding thereto; voltage measuring units, each provided for each of the transit circuits, and for measuring the voltage of the battery module installed in the corresponding transit circuit; and a control unit constituted in such a manner as to allow at least one among discharging completion, charging completion, and fault occurrence to be determined for each battery module installed in each of the transit circuits. The control unit is constituted in such a manner that, when discharging completion, charging completion, or fault occurrence has been determined, the circuit switching unit for the battery module in which the discharging completion, charging completion, or fault occurrence has been determined is caused to switch from the transit circuit to the bypass circuit. |
