Abstract
According to one embodiment, battery module includes a main circuit, a resistive element, a current-amount detection circuit, and a breaker. A charge and discharge current of a battery flows through the main circuit via a positive connecting terminal and a negative connecting terminal. The resistive element is provided in a current path branched from the main circuit, and able to form a closed circuit with an external control device via one of the positive connecting terminal and the negative connecting terminal while an insulating state between the main circuit and the external control device is maintained. The current-amount detection circuit detects an amount of current flowing through the resistive element, and outputs a current-amount detection signal. The breaker circuit interrupts the current flowing through the main circuit when the amount of current flowing through the resistive element is smaller than a predetermined threshold current based on the current-amount detection signal.
