Abstract

Abstract: Energy management control strategy is one of the key technologies in the development of extended-range fuel cell vehicles. During the use of vehicles, fuel cell performance will decline, which limits the power output of the stack and the life of the stack. In order to control the power output of the fuel cell more reasonably, in this paper, the lumped parameter model of fuel cell is built based on Matlab/Simulink, and the vehicle model is built by AVL/Cruise simulation software. Combined with the fuel cell health state (SOH: State of Health) estimation method, the vehicle demand power and the state of charge (SOC: State of Charge) value of the power battery are used as input, and an energy management control strategy architecture based on the performance degradation of the fuel cell is designed. The simulation results show that the designed energy management can improve dynamic performance, and avoid frequent start and stop of the fuel cell, prolong the service life of the fuel cell, and further improve the economy of the vehicle.
