PROBLEM TO BE SOLVED: To provide an operating machine capable of appropriately managing a remaining capacity of a battery.SOLUTION: According to the present disclosure, an operating machine comprises: a battery controller 35 computing a remaining capacity of a battery; a charge-discharge request amount computing unit 41A computing a charge/discharge request amount for keeping electric power output from the battery in a predetermined range on the basis of the computed remaining capacity; a target rotating speed computing unit 41B computing a target rotating speed command value to a motor-generator; and an inverter 32 controlling the motor-generator according to the computed target rotating speed command value, and is configured such that at least one of the battery controller 35 and inverter 32 computes an actual charge/discharge amount of the battery 34, and the target rotating speed computing unit 41B calculates a target rotating speed correction value from a difference between the charge/discharge request amount and the actual charge/discharge amount and corrects the target rotating speed command value.SELECTED DRAWING: Figure 3
【課題】バッテリの蓄電残量の適切な管理を可能とする作業機械の提供。【解決手段】本発明は、バッテリの蓄電残量を演算するバッテリコントローラ35と、演算した蓄電残量に基づき、バッテリが出力する電力を、所定の範囲に保つための充放電要求量を演算する充放電要求演算部41Aと、電動発電機の目標回転数指令値を演算する目標回転数演算部41Bと、演算した目標回転数指令値に応じて電動発電機を制御するインバータ32とを有し、バッテリコントローラ35およびインバータ32の少なくとも一方は、バッテリ34の実際の充放電量を演算し、目標回転数演算部41Bは、充放電要求量と、実際の充放電量との差から目標回転数補正値を算出して目標回転数指令値を補正する構成にしてある。【選択図】図3
