摘要：AbstractThis paper deals with a sizing and Energy Management Strategy (EMS) of a hybrid source composed by a Fuel Cell as a main source and battery pack as a secondary one for automotive application. The fuel cell is connected via a DC/DC boost converter to DC link and a bidirectional DC/DC converter is used to connect the batteries to the DC link. A sizing algorithm is used to determine the hybrid source sizes. The simulations results confirm the benefits of hybridization in term of weight, volume, cost and hydrogen consumption. Furthermore, an Energy Management strategy based on frequency splitting is used to split the power between the Fuel Cell and the battery pack by determining the power profile of each one. The proposed strategy shows good performances through the simulation resultsMoreover, it is validated experimentally via a test bench of 750 W using tow cycles. Experimental results confirm the efficiency, robustness and stability of the proposed approach regrading dynamic performances during power demand, and regenerative braking.
