Hybrid Power System Supply for Electric Vehicles

In this paper a hybrid power system for electric vehicles is proposed. The power system combines two complementary technologies: fuel cells and one storage element (supercapacitor). The objective of this paper is to maintain a high level of reliability with minimal cost through optimal design of a hybrid electric vehicle system. For this reason, it is presented the optimum design method of a hybrid power generation system. The primary objective of this study was to propose a strategy for the control of an electric vehicle powered by a source consisting of a fuel cell main source and the auxiliary power supercapacitor. The fuel cell supply is made by using the electrolysis of water. Modelling and control design of the hybrid system is validated by using the Matlab/Simulink software environment.
