POWER SOURCE CONTROL APPARATUS APPLIED TO A COMBAT MANEUVER EQUIPMENT AND ITS OPERATING METHOD, AND MILITARY HYBRID ELECTRIC PROPULSION SYSTEM USING THE OPERATING METHOD

摘要

The present invention relates to a power source of a series type hybrid electric propulsion system comprising an engine-generator, a battery, and an ultracapacitor. The present invention comprises modules for implementing maximum system efficiency by multiplying engine-generator efficiency with battery efficiency when the value of the state of charging (SOC) of the battery is lower than a SOC threshold, implementing maximum system efficiency by adding the engine-generator efficiency and battery efficiency for controlling the driving range of the battery in a section where the SOC is high when the SOC value of the battery is higher than the SOC threshold, and enhancing the overall system efficiency by lowering power supplied respectively to the battery and the ultracapacitor through distributing the power by combining the output of the battery with the output of the ultracapacitor. The present invention can improve the efficiency of the overall system by controlling the power source while simultaneously considering the efficiencies of the engine-generator, the battery, and the ultracapacitor.
