Abstract
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.
