    • 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.
    • 本发明的目的在于提供一种混合动力建筑机械,其能够使蓄电装置快速预热,并且能够提高蓄电装置的使用寿命。 该混合动力建筑机械配备:原动机(1); 电动机,其补充原动机(1)的动力并产生电力; 蓄电装置(8),其向所述电动机传递动力并从所述电动机接收动力; 使来自原动机(1)或电动机的废热加热的加热介质或加热器(40)循环到蓄电装置(8)附近的预热电路(25)。 控制上述蓄电装置(8)的充放电和上述预热电路(25)的加热介质的循环的控制装置; 以及测量外部气温的外部气温测量装置。 控制装置通过加热介质执行预热操作,响应于由外部空气温度测量装置(8)测量的外部空气温度来确定是否执行用于预热操作的蓄电装置(8)的充电/放电 外部空气温度测量装置,并且执行预热操作,在该预热操作中同时进行通过蓄电装置(8)的充电/放电的预热操作。
