Abstract

An electric working machine includes battery packs, an actuated device to be actuated by electricity supplied from the battery packs, and a controller to control discharging of the battery packs based on remaining charge levels of the battery packs. The controller is configured/programmed to select one of the battery packs as a discharging battery pack, and perform a limiting process to limit electricity supplied from the discharging battery pack to the actuated device when the remaining charge level of the discharging battery pack is less than a limit threshold, and cause the limit threshold and/or content of the limiting process to differ between when one or more of the battery packs that are other than the discharging battery pack have a remaining charge level of a second threshold or more and when any of such battery packs do not have a remaining charge level of the second threshold or more.
