Abstract: At present, the national policy encourages the development of hydrogen fuel cell automobiles, but there is little research on the matching design of power system of hydrogen fuel cell dump automobiles. Deeply study the performance and cost of relevant system components of hydrogen fuel cell dump automobiles, consider the usage scenarios of automobiles, and use Cruise software to establish the automobile calculation model for simulation analysis. This paper introduces the overall design scheme of hydrogen fuel cell dump automobiles. The matching design of power system includes the composition structure of control system, the selection of motor and speed ratio, the selection of power cell and the selection of hydrogen fuel cell system. The power system is arranged, and a power system of hydrogen fuel cell dump automobiles is developed, which provides a reference for the design of hydrogen fuel cell dump automobiles.
