Parameter Matching and Energy Management Strategy Simulation Analysis of Fuel Cell Heavy Truck Power System
In order to improve the comprehensive performance of the fuel cell heavy truck,the configuration scheme of its power system is determined firstly,the selection and parameter matching of the motor,fuel cell and power battery are carried out ac-cording to the power and economy requirements of the vehicle,the physical model of the whole vehicle is built by AVL Cruise soft-ware.An energy management strategy based on fuzzy control method is developed,the energy management strategy model of fuzzy control is established under MATLAB/Simulink environment.The joint simulation of energy management strategy model and vehicle physical model is realized by MATLAB DLL.The simulation results show that the design scheme of vehicle power sys-tem and the energy management strategy proposed can meet the vehicle power performance and effectively improve the fuel economy of the vehicle.
