Abstract
An operating machine includes: a charging time estimation unit that estimates a first estimated charging time required to restore a capacity of a first battery from a first estimated residual capacity to a target capacity value of the first battery and a second estimated charging time required to restore a capacity of a second battery from a second estimated residual capacity to a target capacity value of the second battery; a capacity management implementation unit that implements capacity management on the first battery and the second battery such that the first battery is charged for the first estimated charging time and the second battery is charged for the second estimated charging time; and a discharge amount limitation unit for limiting a discharge amount of the second battery during an idling stop so that a residual capacity of the second battery after discharge is maintained at or above a set value.
