Disclosed is a hybrid construction machine which comprises a temperature detection unit, a determination unit, a distribution ratio setting unit, and a regeneration amount control unit. The temperature detection unit detects the temperature of a battery connected to a motor generator. The determination unit determines whether the temperature of the battery is lower than a threshold value of a low temperature region or higher than a threshold value of a high temperature region. If the temperature of the battery is lower than the threshold value of the low temperature region or higher than the threshold value of the high temperature region, the distribution ratio setting unit controls an output control mechanism that controls the output distribution ratio of the motor generator relative to an engine, so as to reduce the output distribution ratio of the motor generator and increase the output distribution ratio of the engine by the amount by which the output distribution ratio of the motor generator is reduced. In addition, if the temperature of the battery is lower than the threshold value of the low temperature region or higher than the threshold value of the high temperature region, the regeneration amount control unit controls an input control mechanism that controls a hydraulic regeneration amount for a hydraulic motor, so as to reduce the hydraulic regeneration amount for the hydraulic motor. |
