Abstract: A management device for an energy storage device mounted on a vehicle includes a management unit, a component that operates according to an instruction from the management unit and that generates an operation sound, and an acquisition unit that acquires information. The management unit operates the component and diagnoses a failure of the component when the information acquired by the acquisition unit satisfies a predetermined condition indicating a possibility that no person stays within the vehicle and within a certain distance from the vehicle.
