HYBRID POWER CONTROL SYSTEM OF A WORKING MACHINE, CAPABLE OF SWIFTLY RESPONDING TO THE MALFUNCTION OF AN ENERGY STORAGE DEVICE OR TO THE SHORTAGE OF A VOLTAGE

摘要

PURPOSE: A hybrid power control system of a working machine is provided to drive a secondary motor with an emergency driver by transferring maximized engine output to the secondary motor.;CONSTITUTION: A hybrid power control system of a working machine comprises: an engine(10); an engine pilot motor(11) which is connected to the engine output shaft and generates surplus power; a hydraulic pump(12) which supplies hydraulic oil to one or more motor under a work load or traveling; a first inverter(16) which controls the operation of the engine pilot motor; an energy storing device(19) which stores electrical energy which is generated by the engine pilot motor; and a converter(18) which is arranged between the first inverter and the energy storing device.;COPYRIGHT KIPO 2010
