Four Wheel Electric Vehicle Behavior Using Fuel Cell Supply Moving on Mountain Region Condition

Autonomy is one of a most problems for commercialized electric vehicles.Especially that uses four wheels for motions.The weakest point for this kind is the battery energy management system, to solve this problem a Proton Exchange Membrane Fuel Cell is used.The PEMFC autonomy depends on storage state of fuel, in this work we focuses the relationship between mountain slope road effect and PEMFC power consumption behavior.In this study, the variation of the slope angle during trajectory is made and the behavior of PEMCF energy is presented in each steps.Simulations are carried on Matlab software.The proposed energy system develops the autonomy and gives more positive signs on stability for this vehicle moving on slope road condition with different road angles, the fuel cell response is quickest compared with lithium battery moving in the same condition.
