ELECTRIC WORKING MACHINE AND METHOD OF ACTIVATING ELECTRIC WORKING MACHINE
An electric working machine includes an electric device, electric circuitry, battery packs to be connected sequentially to the electric device via the electric circuitry to parallelly connected, the battery packs including internal relay(s) to open/close an internal circuit, and a controller. The electric circuitry includes external relays corresponding to respective battery packs. The controller is configured or programmed to perform a first latter process wherein, while a first battery pack to be connected first to the electric device is in electrical connection with the electric device, the controller brings the internal relay(s) of a second battery pack to be connected second or later to the electric device into a closed state, and a second latter process wherein the controller brings, into the closed state, the external relay corresponding to the second battery pack where the internal relay(s) is in the closed state.
