Abstract: In regard to the energy crisis, FCHVs are one of the alternative options for conventional vehicles. One of the problems in HVs is retaining the state of charge (SoC) of the battery in driving conditions. In this paper, a new power management system with fuzzy logic controller and dynamically focused learning is used for reducing fuel consumption and retaining the SoC of the battery. The vehicle powertrain is modelled and simulated in Matlab-Simulink and advanced vehicle simulator software (ADVISOR). The results demonstrate that the proposed control strategy can satisfy the power requirement and retain the SoC of the battery in four different driving cycles. In addition, the results of the hybrid model are compared with default model in advisor with SoC correction. Finally, a well to wheel efficiency analysis is used on Samand vehicle to compare energy consumption, fuel cost and CO2 emission between proposed controller and common controller.
