Hybrid construction machine and method for controlling the same
Provided is a hybrid construction machine together with a method for controlling that construction machine in a manner ensuring the operability of its combined operations regardless of fluctuations in the load on its work machine. The hybrid construction machine has: a swing structure; a work machine attached to the swing structure; an engine mounted on the swing structure; a first electric motor driven by the engine, the motor being capable of generating power; a hydraulic pump driven by the engine and the first electric motor; a second electric motor for driving the swing structure; and a plurality of electric storage devices, wherein the hybrid construction machine further includes a first control unit which, in a combined operation involving the work machine and the swing structure, drives and controls the second electric motor by use of the electric power supplied from at least one electric storage device selected from the storage devices and from another electric storage device offering a higher output level and a lower stored energy level per unit weight than the selected at least one electric storage device, and drives and controls the hydraulic pump by use of the engine.
