Abstract: 4×2 hydrogen fuel cell heavy truck is the research object in this paper, and its vehicle power system is studied. Firstly, the power system structure of hydrogen fuel cell truck is studied. Secondly, the structural form of the power system of the hydrogen fuel cell heavy truck is comprehensively analyzed, and the power system structure of the hybrid drive of the fuel cell and the traction battery is selected, and the power system components of the hydrogen fuel cell heavy truck are selected and the parameters are matched. Finally, AVL Cruise is used to establish the whole vehicle model of hydrogen fuel cell heavy truck, set the parameters of each module in the whole vehicle model, and test the dynamic performance of the whole vehicle of hydrogen fuel cell heavy truck. The results show that the power performance of the hydrogen fuel cell heavy truck is good, which provides a reference for further optimization of the power system.
