Abstract
On the basis of the power, efficiency and hydrogen consumption curves of fuel cell, and its operating point efficiency, combining the optimal working area of battery SOC, focuses on a hybrid vehicle energy system powered by fuel cell and battery, builds up a model based on the Simulink platform, and proposes a new energy management and control strategy. The simulation result shows that the proposed strategy can effectively distribute the energy of the fuel cell and battery, and ensure the high-efficiency power output of fuel cell and the optimal working area of battery SOC.
