A Model for the Dynamic Simulation of Hybrid Vehicles with Pem Fuel Cell

The paper focuses on the development of a dynamic model for a hybrid vehicle equipped with a PEM fuel cell and a battery pack. An integrated structure of mathematical models has been implemented, whose development is based on previous studies carried out by the research group on the modeling of energy conversion systems for conventional and hybrid vehicles. The whole model simulates real driving cycles aiming at providing the data needed for selecting the best control strategies in terms of performance and fuel economy. A comparison with thermal-hybrid vehicles and conventional systems performance is presented together with an energy analysis carried out for both the single stack and its auxiliaries and the overall system (vehicle
