Title:
Hybrid type construction machinery
Document Type and Number:
Japanese Patent JP6220698
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a hybrid type construction machine comprising a battery temperature controller that can maintain the heat transfer efficiency between a power storage device and a heat exchange member with stability, independently of change in environmental temperature.SOLUTION: A power storage device 8 is configured to have a plurality of battery cells 30 laminated via an insulation separators 31. Each of the plurality of battery cells 30 has one surface thermally coupled with a water jacket 24 that is a heat exchange member via a heat conduction sheet 36, and is fixed to the heat exchange member 24 by using a fixing member so that a compressive force acts on the heat conduction sheet 36. The fixing member is configured to include an upper stay 34 pressing the battery cell from above.
