본 발명의 목적은, 축전 장치를 신속히 난기함과 함께, 축전 장치의 수명을 향상시킬 수 있는 하이브리드식 건설 기계를 제공하는 데 있다. 원동기(1)와, 원동기(1)의 동력의 보조 및 발전을 행하는 전동기와, 상기 전동기와의 사이에서 전력의 수수를 행하는 축전 장치(8)와, 원동기(1) 또는 상기 전동기의 배열 또는 히터(40)에 의해 데워진 가온 매체를 축전 장치(8)의 근방에 순환시키는 난기 회로(25)와, 축전 장치(8)의 충방전과 난기 회로(25)의 가온 매체의 순환을 제어하는 제어 장치와, 외기 온도를 계측하는 외기 온도 계측 장치를 구비하고, 상기 제어 장치는, 상기 가온 매체에 의한 난기 운전을 행함과 함께, 상기 외기 온도 계측 장치로 계측하는 외기 온도에 따라, 난기 운전을 위한 축전 장치(8)의 충방전을 행할지 여부를 판정하고, 축전 장치(8)의 충방전에 의한 난기 운전을 병용한 난기 운전을 실행한다.

    The object of the present invention is to provide a hybrid construction machine that can quickly warm up an electrical storage device and can improve the service life of the electrical storage device. This hybrid construction machine is equipped with: a prime mover (1); an electric motor that supplements the power of the prime mover (1) and generates electric power; an electrical storage device (8) that transmits power to and receives power from the electric motor; a warm-up circuit (25) that circulates a heating medium heated by waste heat from the prime mover (1) or the electric motor, or by a heater (40), to the vicinity of the electrical storage device (8); a control device that controls charging/discharging of the electrical storage device (8) and circulation of the heating medium of the warm-up circuit (25); and an outside air temperature measurement device that measures the outside air temperature. The control device executes warm-up operation by means of the heating medium, determines whether or not to execute charging/discharging of the electrical storage device (8) for the purpose of the warm-up operation in response to the outside air temperature measured by the outside air temperature measurement device, and conducts warm-up operation in which the warm-up operation by charging/discharging of the electrical storage device (8) is effected simultaneously.
