Simulation and optimization of hydrogen consumption in a fuel cell/battery hybrid vehicle

Abstract

This paper presents a physics-based mathematical model for a fuel cell hybrid vehicle system. The performance design of fuel cell hybrid electric vehicles (FCHEVs) is an area of interest in transportation applications. FCHEV is a combination of a proton exchange membrane fuel cell (PEMFC), with a battery and associated DC/DC and DC/AC converters. Suitable batteries are used in FCHEV acts as a backup system with efficient energy management. The battery is designed for fast power transfer during transient response and constant performance without hydrogen. The power management schemes discussed are consistent with the most common modern power management techniques used in fuel cell vehicle applications, including: the state engine control strategies, rule-based fuzzy logic strategies, classical proportional integral control strategies, frequency fuzzy logic decoupling/control minimization strategies. Therefore, we tested and evaluated the reliability of the model using the MATLAB/Simulink environment, with mixed results.

Energy management strategy for photovoltaic powered hybrid energy storage systems in electric vehicles

“…As a result, the process of obtaining the ideal working situation moves along more quickly and with fewer oscillations [28]. If the irradiance is higher, P&O observed, 𝑑𝑉 and 𝑑𝐼 as null and hence, the duty cycle is developed through 𝛥𝐷𝑛 that is stated as variable step size which is represented in (14).…”

“…For PV systems to handle the brief surge in current needed at specified times, enough battery capacity becomes essential [14]. To regulate the power generated by renewable sources, a flexible power conversion technique is necessary [15].…”

“…This paper examines scientific articles on the functioning of hybrid wind-hydrogen energy complexes in order to identify promising areas for new scientific research works [13]- [15]. The list of the highlighted prospective scientific research topics is presented in the "results and discussion" part.…”

Effect of proton radiation on gallium nitride light emitting diodes

“…Amphoteric doped LEDs show shorter response times than heterostructure LEDs because the minority carriers have longer lifetimes. Simulation and modelling techniques can also be used to evaluate the dependability of these devices [21]- [23]. Irom et al [24] shows proton damage to the phototransistor and LED of the Micropac 66179 optocoupler.…”
