Fuel Cell Hybrid Systems for Electric Vehicles

Abstract

This paper presents an adoptive current sharing method for fuel cell and battery fed dc drive system for
electric vehicle application. Also investigation of different power management techniques suitable for fuel cell and
battery hybrid power source for electric vehicle application presented. The control algorithm makes sure that total
load is shared between the two sources during transients and heavy load. The controller facilitates fuel cell to operate
in normal load region during transient and steady state by sharing unevenly the required load power between the two
sources. The effectiveness of the proposed scheme is verified through simulation using MATLAB/Simulink software.
