PROBLEM TO BE SOLVED: To provide a construction machine that performs current engine starting while taking into account power necessary for engine starting next time.SOLUTION: When starting an engine 9 using an assist power generation motor 10, a main controller 28 lowers a lower limit of a charge and discharge range of a power storage device 19 from a first lower limit min1 to a second lower limit min2 through an energy management control part 28B. When starting of the engine 9 is completed, the main controller 28 raises the lower limit of the charge and discharge range of the power storage device 19 from the second lower limit min2 to the first lower limit min1. In addition, when starting of the engine 9 is completed, and an SOC of the power storage device 19 is below the first lower limit min1, the main controller 28 causes a display device 30 to display engine stop prohibition information.SELECTED DRAWING: Figure 2 |
