ELECTRIC WORKING MACHINE AND METHOD OF CONTROLLING ELECTRIC WORKING MACHINE
An electric working machine (1) includes battery packs (41), an actuated device (E) to be actuated by electricity supplied from the battery packs (41), and a controller (30) to control discharging of the battery packs (41) based on a remaining charge level of each of the battery packs (41). The controller (30) is configured or programmed to select one of the battery packs (41) as a discharging battery pack to supply electricity to the actuated device (E), and perform a limiting process to limit electricity supplied from the discharging battery pack (41) to the actuated device (E) when the remaining charge level of the discharging battery pack (41) 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 (41) that are other than the discharging battery pack (41) have a remaining charge level more than or equal to a second threshold and when any of the one or more of the battery packs (41) that are other than the discharging battery pack (41) do not have a remaining charge level more than or equal to the second threshold.
