MODELING an‎d SIMULATION OF FUELCELL BATTERY HYBRID VEHICLE an‎d POWER MANAGEMENT CNTROLLER DESIGN

A hybrid vehicle structure used Fuel-Cell/Battery has been proposed, and an intelligent controller has been designed to power management. Elimination of the gasoline engine, an electrical machine can enforce requested power for driving and braking so, regenerative braking is possible in proposed structure. Fuel-cell is connected to battery as a DC bus via a DC/DC converter which can control the fuel-cell current by its switching control. A power demand feedback is considered, and the controller decision is based on this demand at the previous time step. Moreover, braking pedal displacement and the battery state of charge are considered as controller input signals and its relative decision to power split between two exist power sources. Finally, simulation results for some driving maneuvers, shows that the proposed structure has good performance for the vehicles as a civic automobile with zero emissions
