Abstract
• Building a MATLAB Simulink model to simulate an electric vehicle on a drive cycle. • Simulate tow cases: with battery capacity 75 kw, with hydrogen fuel cell capacity 75 kw. • Simulate tow dive cycle: proposed drive cycle, real drive cycle (NEDC). • Compare distance and power consumption in both. • The future is in favor of hydrogen fuel cells rather than lithium batteries, despite the fact that the later are still feasible now. This research puts forward the modeling of a Hydrogen Fuel Cell Electric Vehicle (HFCEV) and its validation, in comparison with battery electrical vehicle (BEV) based on a postal vehicle and its subsystems. The main investigation parameters are the amount of hydrogen consumed, and the change in the state of charging of the battery. For the profile of the same speed route, an HFCEV model and a BEV model, consisting of multiple subsystems, were developed, and simulated in the MATLAB® Simulink environment. We make use of various sources of drive cycles to obtain our outcomes such as the New European Diving Cycle (NEDC). By running simulations for different stages, we are able to generate simulation results. The discrepancies in the graphs and the visual demonstrations guided us to variable conclusions on how different factors affect an electric vehicle’s performance and efficiency. The simulation result shows that the (BEV) is 30% more effective for NEDC drive cycle comparing with (HFCEV).
