ELECTRIC WORKING MACHINE AND METHOD FOR CONTROLLING ELECTRIC WORKING MACHINE
To efficiently perform charging even when a sufficient charge time cannot be secured.SOLUTION: An electric working machine comprises: a plurality of battery packs; an operation apparatus that operates by electric power supplied from the battery packs; a battery monitoring device that detects the remaining capacity of each battery pack; and a control device that controls charging and discharging of the plurality of battery packs on the basis of the remaining capacity of each battery pack. In a discharge mode for supplying electric power to the operation apparatus, the control device determines one of the plurality of battery packs to be a battery pack for discharging that supplies electric power to the operation apparatus, and causes electric power to be supplied from the battery pack for discharging to the operation apparatus. In a charge mode for charging the battery packs, the control device determines preferentially a battery pack whose remaining capacity is large among the plurality of battery packs to be a battery pack for charging and causes the determined battery pack for charging to be charged.SELECTED DRAWING: Figure 1
【課題】充電時間が十分に確保できない場合であっても、効率よく充電を行う。【解決手段】電動作業機は、複数のバッテリパックと、バッテリパックから供給される電力によって作動する作動機器と、各バッテリパックの残容量を検出するバッテリ監視装置と、各バッテリパックの残容量に基づいて複数のバッテリパックの充電及び放電を制御する制御装置と、を備え、制御装置は、作動機器に電力を供給する放電モードでは、複数のバッテリパックのうち、いずれか１つを作動機器に電力を供給する放電用バッテリパックとして決定し、放電用バッテリパックから作動機器に電力を供給させ、バッテリパックの充電を行う充電モードでは、複数のバッテリパックのうち、残容量が多いバッテリパックを優先して充電用バッテリパックとして決定し、決定した充電用バッテリパックの充電を行わせる。【選択図】図１
