ELECTRICALLY-OPERATED WORKING MACHINE
To provide an electrically-operated working machine capable of enhancing the estimation accuracy of a residual charging time or a residual discharging time of a secondary battery.SOLUTION: An electrically-operated shovel comprises: a secondary battery 25; a battery management unit 28; and a vehicle control unit 29. The vehicle control unit 29 predicts a transition of a temperature of the secondary battery 25 on the basis of a temperature and a charging ratio of the secondary battery 25 detected by the battery management unit 28, predicts a transition of a current of the secondary battery 25 on the basis of the predicted transition of the temperature of the secondary battery 25, and estimates a residual charging time or a residual discharging time of the secondary battery 25 on the basis of the predicted transition of the current of the secondary battery 25.SELECTED DRAWING: Figure 2
【課題】二次電池の残充電時間又は残放電時間の推定精度を高めることができる電動式作業機械を提供する。【解決手段】電動式ショベルは、二次電池２５、電池管理ユニット２８、及び車両制御ユニット２９を備える。車両制御ユニット２９は、電池管理ユニット２８で検知された二次電池２５の温度及び充電率に基づいて、二次電池２５の温度の推移を予測し、予測された二次電池２５の温度の推移に基づいて、二次電池２５の電流の推移を予測し、予測された二次電池２５の電流の推移に基づいて、二次電池２５の残充電時間又は残放電時間を推定する。【選択図】図２
