Disclosed is a hybrid construction machine including: an engine (11), a generator-motor (13), a hydraulic pump (21), an electric storage device (41), an elctric power control device (61) which controls electric power between the generator-motor (13) and the electric storage device (41), a temperature detector (51) which determines a temperature of the electric storage device (41), an unload valve (31) provided between a discharge port of the hydraulic pump (21) and a tank (T), an unload-valve control device (63), and a relief valve (33). The power control device (61) controls an electric power to be supplied from the electric storage device (41) to the generator-motor (13), under abnormal circumstances where the temperature of the electric storage device (41)is lower thana predetermined set temperature, to a power obtained by adding an additional discharge power to a power to be supplied under normal circumstances. The unload-valve control device (63) closes the unload valve (31), under abnormal circumstances. The relief valve (33)controls the discharge pressure of the hydraulic pump (21) to the set pressure, under abnormal circumstances.
