An apparatus according to one embodiment includes a positive and a negative electrode terminals; modules each including an assembled battery and a CMU, the assembled battery including cells, the CMU to detect a voltage and a temperature of the assembled battery; a main circuit for electrical connection between terminals of the modules and the positive and negative electrode terminals; a BMU to receive information about the voltage and the temperature from the respective CMU; a supply circuit to convert DC power from the main circuit and supply the converted power to the BMU; a breaker for interrupting the main circuit; and a circuit to block a current flowing through the main circuit in a direction of charging the modules, in response to a stop of a control signal from the BMU.

Storage battery apparatus with current cutoff control

A device according to an embodiment includes at least one assembled battery; first switches that switch an electrical connection state of main circuits connected between the assembled battery and the load; second switches that switch an electrical connection state of second main circuits branched from the main circuits and are connected between the assembled battery and the load; a BMU that controls operations of the first switches based on an operation command supplied from the load; and a power supply circuit that supplies power to the BMU and second switches when a start command supplied from the outside is ON.
