To provide an electric shovel suppressed in lowering of work efficiency.SOLUTION: An electric shovel related to one embodiment of the present disclosure has a battery, an electric motor driven by power supplied from the battery, and a hydraulic drive system for driving a work attachment by the power by the electric motor. When an external power source is chargeably connected to the battery, the electric motor is driven by the power supplied from the external power source to warm up the hydraulic drive system.SELECTED DRAWING: Figure 2
【課題】作業効率の低下を抑制する。【解決手段】本開示の一実施形態に係る電動ショベルは、バッテリと、バッテリから供給される電力で駆動する電動機と、電動機による動力で作業アタッチメントを駆動させる油圧駆動系と、を有し、外部の電源がバッテリに充電可能に接続されている場合に、外部の電源から供給される電力で電動機を駆動させて、油圧駆動系を暖機させるように構成されている。【選択図】図２
