ELECTRIC WORKING MACHINE AND METHOD FOR CONTROLLING ELECTRIC WORKING MACHINE
To efficiently charge a plurality of battery packs.SOLUTION: An electric working machine comprises a plurality of battery packs, an operation apparatus, each battery monitoring device, and a control device. The control device carries out: a desired value setting process for setting a first desired value; a first charging process for determining one of battery packs whose remaining capacity is less than the first desired value as a battery pack for charging, and charging the determined battery pack for charging with a constant current until its remaining capacity reaches the first desired value; a second charging process for switching battery packs for charging when the remaining capacity of the battery pack for charging reaches the first desired value and charging a battery pack for charging after switching with the constant current until its remaining capacity reaches the first desired value; and a third charging process for determining one of the battery packs whose remaining capacity is less than a second desired value that is larger than the first desired value to be a battery pack for charging when there is no battery pack whose remaining capacity is less than the first desired value, and charging the determined battery pack for charging with the constant current until its remaining capacity reaches the second desired value.SELECTED DRAWING: Figure 7
【課題】 複数のバッテリパックを効率良く充電する。【解決手段】電動作業機は、複数のバッテリパックと、作動機器と、各バッテリ監視装置と、制御装置と、を備え、制御装置は、第１目標値を設定する目標値設定処理と、残容量が第１目標値未満であるいずれか１つを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残容量が第１目標値に達するまで定電流充電する第１充電処理と、充電用バッテリパックの残容量が第１目標値に達すると、充電用バッテリパックを切り替え、切り替え後の充電用バッテリパックの残容量が第１目標値に達するまで定電流充電する第２充電処理とを行い、残容量が第１目標値未満であるバッテリパックがない場合、残容量が第１目標値よりも多い所定の第２目標値未満であるバッテリパックのうち、いずれか１つを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残容量が第２目標値に達するまで定電流充電する第３充電処理を行う。【選択図】図７
