Abstract: Combining a Fuel Cell (FC), as primary power source, with a Battery Energy System (BES), as an auxiliary source, for high power demands is a promising approach for future hybrid electric vehicles (HEV). The powertrain control strategy and the component sizing significantly affect the vehicle performance, cost, vehicle efficiency and fuel economy. This paper presents a developed control strategy for optimising the power sharing between sources and components sizing by using Particle Swarm Optimisation (PSO) algorithm. This control strategy implemented on FC/Battery hybrid electric vehicle in order to achieve the best performance with minimum fuel consumption and minimum powertrain components sizing for a given driving cycle with high efficiency. The powertrain and the proposed control strategy have been simulated by Matlab/Simulink. The simulation results have demonstrated that the optimal sizing of the powertrain of FC/battery components and the minimum fuel consumption have been improved by applying the PSO control strategy.
