Optimized EMS and a Comparative Study of Hybrid Hydrogen Fuel Cell/Battery Vehicles

This paper presents a new Fuel Cell Consumption Minimization Strategy (FCFCMS) for Hybrid Electric Vehicles (HEVs) powered by fuel cell and an energy storage system, in order to minimize as much possible the consumption of hydrogen while maintaining State Of Charge (SOC) battery. Compared existing Energy Management Strategies (EMSs) (such well-known Machine (SMC), Fuzzy Logic Control (FLC), Frequency Decoupling FLC (FDFLC), Equivalent (ECMS)), proposed strategy increases overall vehicle efficiency and, therefore, minimizes total respecting constraints each power element. A model hybrid has been built using TruckMaker/MATLAB software. Using Urban Dynamometer Driving Schedule (UDDS), which includes several stops accelerations, performance compared with these different approaches (SMC, FLC, FDFLC, ECMS) through simulations.
