ELECTRIC WORKING MACHINE AND METHOD OF ACTIVATING ELECTRIC WORKING MACHINE
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 an electric device (20) via the electric circuitry (21) such that they are parallelly connected, the battery packs (22) including internal relay(s) (220) to open/close an internal circuit (222), 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 perform a first latter process wherein, while a first battery pack (22) to be connected first to the electric device (20) is in electrical connection with the electric device (20), the controller brings the internal relay(s) (220) of a second battery pack (22) to be connected second or later to the electric device (20) into a closed state, and a second latter process wherein the controller brings, into the closed state, the external relay (211) corresponding to the second battery pack (22) where the internal relay(s) (22) is in the closed state.
