Title:
HYBRID CONSTRUCTION MACHINE
Document Type and Number:
WIPO Patent Application WO/2016/140190
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a hybrid construction machine wherein a power storage device can quickly be warmed up and the service life of the power storage device can be improved. This hybrid construction machine is equipped with: an engine (1); an electric motor that supplements the power of the engine (1) and generates power; a power storage device (8) that transmits power to and receives power from the electric motor; a warmup circuit (25) that circulates a heating medium heated by waste heat from the engine (1) or the electric motor, or by a heater (40), in the vicinity of the power storage device (8); a control device that controls the charging/discharging of the power storage device (8) and the circulation of the heating medium by the warmup circuit (25); and an outside air temperature measurement device that measures the outside air temperature. The control device performs a warmup operation by means of the heating medium, determines whether to perform charging/discharging of the power storage device (8) for the purpose of a warmup operation, in response to the outside air temperature as measured by the outside air temperature measurement device, and executes a warmup operation wherein the warmup operation based on charging/discharging of the power storage device (8) is performed at the same time.
