In the automotive industry, design processes always start with modeling and simulation for fast and cost-effective design prototype validation. Thereafter these simulations must be validated. Electric vehicles feature a wide range of components from different domains with controllers. One of the challenges in modeling and simulation of these vehicles lies in the integration of these diverse components into a single simulation environment. In this paper, an electric vehicle model is implemented along with an integrated hybrid storage system in MATLAB/Simulink. The hybrid energy storage system encompasses a proton exchange membrane (PEM) fuel cell system and a Lithium-ion battery, which are linked together via a current-regulated DC-DC converter. The simulated fuel cell vehicle model allows us to explore different power management strategies.
