POWER SUPPLY DEVICE FOR HYBRID CONSTRUCTION MACHINERY, AND METHOD THEREFOR

摘要

The present invention relates to a power supply device for hybrid construction machinery and, more particularly, to a power supply device for hybrid construction machinery that can reduce the engine load and improve engine efficiency by excluding an ignition motor generally used in hybrid construction machinery and an alternator for battery charging from hybrid construction machinery such as a hybrid excavator and a hybrid vehicle which uses an engine and an electric motor as common power sources and which has an electric energy storage device, and to a method for same.
