摘要：
A control device of construction machine that performs tasks by driving a hydraulic pump 103 by means of an electric motor 102 that is driven by electric power of a battery device 111 that is capable to charge and discharge and an engine 101 that is mechanically coupled to the electric motor 102, includes: a charging/discharging control unit that controls the charging/discharging of the battery device 111 in such a manner that, in case that a heavy load task where an output of the hydraulic pump 103 is large and a light load task where the output of the hydraulic pump 103 is small are alternately performed, when the output of the hydraulic pump 103 during the heavy load task is increased or a time proportion of the heavy load task in the unit period is increased, an average value of charging current of the battery device 111 per the unit period increases, and when the output of the hydraulic pump 103 during the heavy load task is further increased or the time proportion of the heavy load task in the unit period is further increased, then the average value of the charging current of the battery device 111 per the unit period decreases.
