Abstract: A battery management device manages an energy storage device to which a shunt resistor is connected. The battery management device includes: a current measurement unit that measures a current flowing through the shunt resistor using a pair of signal wires connected to both ends of the shunt resistor; a connecting wire that connects the signal wire to a reference potential source via an opening/closing switch; and a determination unit that determines presence or absence of a failure in which connection between the pair of signal wires via the shunt resistor becomes defective based on a change in current measured by the current measurement unit when the opening/closing switch is opened and closed.
