Abstract

A hybrid construction machine which can improve temperature control efficiency of an electrical storage device. It includes an engine, an assisting electricity generation motorwhich performs assistance of power for the engineand electricity generation and an electrical storage devicewhich performs transfer of electric power with this assisting electricity generation motor. The electrical storage deviceincludes a plurality of battery cells, a housingwhich covers the plurality of battery cellsin a state of leaving them separated, a cooling platewhich is attached to this housingand performs heat exchange with the plurality of battery cells, and a projectionwhich is interposed between the housingand the cooling plateand hinders heat transfer between the housingand the cooling plate
