A power flow management based on State Logic Control (SLC) for the hydrogen fuel cell hybrid electric vehicle (FCEV) is proposed in this paper. To improve the dynamic response of the fuel cell generator and reduce the fuel consumption the developed hybrid system has been integrated with the battery and ultracapacitor energy storage resources. SLC has been designed to satisfy the performance of vehicle in terms of fuel consumption, battery state-of-charge (SOC), fuel cell output voltage fluctuations, FC stack efficiency, overall system efficiency, and DC link voltage regulation. Cascade controller has been utilized to control the power conditioning unit of the FCEV, regulate the DC link voltage and manage the battery and ultracapacitor SOC. The proposed energy management system in combination with the converters’ controller is capable of tracking the preferred fuel cell power and retains the DC link voltage nearby its nominal level. This can be done by providing propulsion power and recovering braking energy. The model of vehicle dynamic load is developed by the ADVISOR software, while the MATLAB & Simulink are used to prove the efficacy of the proposed power management system. Processor-In-the-Loop (PIL) approach has been used to validate the source code algorithm of the developed energy management scheme. To do that, Xilinx ISE 14.6 is used as a project aid to interface with FPGA card for synthesis and implementation the validation approach.
