PROBLEM TO BE SOLVED: To provide a hybrid construction machine capable of properly using a power storage device in a low temperature state.SOLUTION: An HCU 37 comprises a battery low temperature reduction output arithmetic operation part 71A for determining battery low temperature reduction output PbL for setting as a large value for lowering the battery temperature Tb when determining that the power storage device 31 is a low temperature state by the battery temperature Tb, a hydraulic fluid low temperature reduction output arithmetic operation part 71B for determining hydraulic fluid low temperature reduction output PoL for setting as a large value for lowering the hydraulic fluid temperature To when determining that a hydraulic fluid is a low temperature state by the hydraulic fluid temperature To and an output command arithmetic operation part 80 for controlling vehicle body operation in response to the sum total of the battery low temperature reduction output PbL and the hydraulic fluid low temperature reduction output PoL.SELECTED DRAWING: Figure 4

    【課題】 低温状態で蓄電装置の適切な利用が可能なハイブリッド建設機械を提供する。【解決手段】 HCU37は、バッテリ温度Tbによって蓄電装置31が低温状態であると判断したときに、バッテリ温度Tbが低くなるに従って大きい値とするバッテリ低温減少出力PbLを決定するバッテリ低温減少出力演算部71Aと、作動油温度Toによって作動油が低温状態であると判断したときに、作動油温度Toが低くなるに従って大きい値とする作動油低温減少出力PoLを決定する作動油低温減少出力演算部71Bと、バッテリ低温減少出力PbLと作動油低温減少出力PoLとの和に従って車体動作を制御する出力指令演算部80とを有している。【選択図】 図4
