ELECTRIC WORKING MACHINE
To enable maintenance of a hydraulic system and a battery to be performed at appropriate timings.SOLUTION: A hydraulic excavator as an electric working machine comprises a charger that supplies power to a battery from an external power source to charge the battery, an electric motor driven by power from the battery, a hydraulic system including a hydraulic pump driven by the electric motor and a hydraulic actuator supplied with pressurized oil by the hydraulic pump, a control unit that manages the physical quantity that indicates the operating state of the electric motor as first operating information, and manages the physical quantity that indicates the operating state including charging and discharging of the battery as second operating information, and an output unit for outputting first operating information and second operating information.SELECTED DRAWING: Figure 2
【課題】油圧系およびバッテリのメンテナンスを、それぞれ適切なタイミングで行うことを可能にする。【解決手段】電動式作業機械としての油圧ショベルは、外部電源からバッテリに電力を供給してバッテリを充電する充電器と、バッテリから供給される電力によって駆動される電動モータと、電動モータによって駆動される油圧ポンプ、および油圧ポンプによって圧油が供給される油圧アクチュエータを含む油圧系と、電動モータの稼働状態を示す物理量を第１稼働情報として管理するとともに、バッテリの充電および放電を含む稼働状態を示す物理量を第２稼働情報として管理する制御部と、第１稼働情報および第２稼働情報を出力する出力部と、を備える。【選択図】図２
