The hybrid construction machine includes an engine 11, an electric motor/generator 14, a hydraulic pump unit 17, an electricity storage device 16, an inverter 15, a temperature regulator (16D or 16E), and a hybrid control unit 22. The hybrid control unit 22 executes at least one of first control for controlling a warming-up battery temperature regulator 16D so that it increases a temperature of the electricity storage device 16, second control for controlling the inverter 15 so that it reduces the power output from the inverter 15, and third control for controlling a pump capacity control unit 21 so that it reduces the flow rate of a hydraulic fluid delivered from the hydraulic pump unit 17, according to a charge/discharge history of the electricity storage device 16.
