Abstract:
Unlike fossil fuels, every study for the effective use of hydrogen/battery source hybrid energy sources in electric vehicles has gained importance because it is a clean energy source alternative for the solution of the global climate change problem. In this study, a system design for monitoring the electrical responses of an electric vehicle whose aerodynamic and mechanical properties are modeled with a hybrid energy system originating from hydrogen and a charged battery group has been studied. The effects of the battery and hydrogen systems of the electric vehicle on variable speed references under different road conditions were investigated. Buck-Boost, one of the basic DC/DC converter types, was used in the circuit and it was controlled for efficient use of energy with power equalization. The simulation of the control system designed to meet the electrical power demands of the electric vehicle of the fuel cell and battery group energy sources has also been developed. The components of the whole system, such as sources, electrical loads, DC/DC converters and control structures, and dynamic cycle operations are modeled in the MATLAB/Simulink environment and this model is fully validated under variable load conditions. In addition, filters are used to correct the waveform of the voltage on the loads and reduce the harmonics, and the efficiency of these filters is shown graphically.
