PROBLEM TO BE SOLVED: To provide a hybrid construction machine which can quickly warm up a power storage device and improve the service life of the power storage device.SOLUTION: A hybrid construction machine includes: a motor which performs assistance of the power of an engine and power generation; a power storage device which transfers power with the motor; a warming-up circuit which circulates a heating medium near the power storage device; a control device 11 which controls the circulation of the heating medium of the warming-up circuit; and mounted apparatus state detection units 1a, 16A, 19, 33, 34, 51, 60-62 which detect the state of a mounted apparatus in order to estimate a request output of the mounted apparatus with respect to the power storage device. The control device 11 controls the circulation of the heating medium on the basis of the temperature of the power storage device and a determination temperature for determining whether or not the heating medium of the warming-up circuit is circulated, and changes the determination temperature in accordance with the detection results in the mounted apparatus state detection units.SELECTED DRAWING: Figure 11

    【課題】本発明の目的は,蓄電装置を迅速に暖機すると共に,蓄電装置の寿命を向上させることができるハイブリッド式建設機械を提供することにある。【解決手段】原動機の動力の補助及び発電を行う電動機と、電動機との間で電力の授受を行う蓄電装置と、加温媒体を蓄電装置の近傍に循環する暖機回路と、暖機回路の加温媒体の循環を制御する制御装置11とを備えるハイブリッド式建設機械において、蓄電装置に対する搭載機器の要求出力を推定するために搭載機器の状態を検出する搭載機器状態検出部1a,16A,19,33,34,51,60〜62を備え、制御装置11は、蓄電装置の温度と暖機回路の加温媒体を循環させるか否かを判定する判定温度とに基づいて加温媒体の循環を制御すると共に、搭載機器状態検出部における検出結果に応じて判定温度を変更する。【選択図】 図11
