ELECTRIC WORKING MACHINE
To provide an electric working machine capable of preventing arc discharge from occurring when a power supply cable is connected.SOLUTION: An electric working machine is an electric working machine equipped with a hydraulic actuator that uses as a hydraulic power source a hydraulic pump driven by a battery and an electric motor that can use the battery as a driving power source, and makes it possible to supply power to the battery from an external power source connected to a power supply cable in a cut-off state in which power supplied from the battery to the electric motor is cut off by detecting that the rotation of the electric motor has stopped, that a switch has been used to select power supply to the battery, and that a power supply cable has been connected to a power supply port connected to the battery.SELECTED DRAWING: Figure 5D
【課題】給電ケーブルを接続した場合にアーク放電が起こることを防止できる電動式作業機械を提供する。【解決手段】電動式作業機械は、バッテリと、前記バッテリを駆動電源とすることができる電動モータによって駆動される油圧ポンプを油圧源とする油圧アクチュエータを備える電動式作業機械であって、前記電動モータの回転が停止し、スイッチにより前記バッテリに給電することが選択されることと、給電ケーブルが前記バッテリと繋がる給電口に接続されることとが検知されることにより、前記バッテリから前記電動モータに供給される電力が遮断された遮断状態で、前記給電ケーブルと繋がる外部電源から前記バッテリに給電することが可能となる。【選択図】図５Ｄ
