This paper presents a novel method for the estimation of the lead-acid battery initial state of charge (SOC) using the battery impedance measurement. The initial SOC is a crucial value used in the commonly used Coulomb counter. An experimental test bench for battery characterization and impedance measurement is built using CompactRio and Labview software. A very simple electrical circuit is proposed...
A hybrid electric vehicle (HEV) is a combination of two power sources: one unidirectional power source based on an internal combustion engine (ICE) (gasoline or diesel fueled), and the other bidirectional based on batteries or electric energy storage subsystem, plus electric machines (EMs). No matter how these two power sources are combined, a hybrid vehicle has the same basic energy flow. From this...
A hybrid electric vehicle is a combination of two power sources: one unidirectional power source based on an internal combustion engine (ICE), and the other bidirectional based on batteries or electric energy storage, plus electric machines (EM). Different ways of combination lead to different vehicle architectures. But these hybrid vehicles have the same basically energy flow paths. So from this...
This document introduces the control structure development for the fuel processing unit of a pressurized, low temperature fuel cell system fed by commercial diesel. The control structure is developed using an inversion based method derived from the causal, graphic modeling approach called energetic macroscopic representation. Its inversion leads to the maximum control structure. It has been applied...
