One or more example embodiments of the present invention include an electric device (20), electric circuitry (21), battery packs (22) to be connected sequentially to the electric device (20) such that they are connected in parallel, and a controller. The electric circuitry (21) includes external relays (211) corresponding to the respective battery packs (22). The controller is configured or programmed to specify each battery pack (22) as being a battery pack requiring a test process to examine opening and closing actions of internal relay(s) (220) of the battery pack (22) or a battery pack not requiring the test process, and in connecting the battery packs (22) to the electric device (20), perform the test process on battery pack(s) (22) that have been specified as requiring the test process to examine the opening and closing actions, and not perform the test process on battery pack(s) (22) that have been specified as not requiring the test process to examine the opening and closing actions.
