PROBLEM TO BE SOLVED: To provide a hybrid construction machine which can quickly warm up a power storage device and improve the service life of the power storage device.SOLUTION: A hybrid construction machine includes: a motor which performs assistance of the power of an engine and power generation; a power storage device which transfers power with the motor; a warming-up circuit which circulates a heating medium near the power storage device; a control device 11 which controls the circulation of the heating medium of the warming-up circuit; and mounted apparatus state detection units 1a, 16A, 19, 33, 34, 51, 60-62 which detect the state of a mounted apparatus in order to estimate a request output of the mounted apparatus with respect to the power storage device. The control device 11 controls the circulation of the heating medium on the basis of the temperature of the power storage device and a determination temperature for determining whether or not the heating medium of the warming-up circuit is circulated, and changes the determination temperature in accordance with the detection results in the mounted apparatus state detection units.SELECTED DRAWING: Figure 11
