摘要

The propulsion system of aircraft electric propulsion tends to develop in the form of mixed energy. Different types of sources have different characteristics. The coordinated work of mixed energy can improve the performance of the power system. The energy form of the aircraft electric propulsion system studied in this paper is a hybrid energy source made of fuel cells and lithium batteries. In view of the particularity of the working conditions of the UAV power system, based on the above rule-based energy management strategy research, this paper proposes a dy-namic balance energy management strategy based on fuel cell hydrogen consumption to make the fuel cell and auxiliary power energy The consumption is in a relatively balanced state, which avoids the situation where one of the power sources is depleted first, can meet the changes of various working conditions, improves the energy utili-zation and stability of the mixed power source, and ensures the reliability of the UAV power system. The results of simulation analysis prove the feasibility. Finally, the hardware of the energy management system is designed and verified by experiments. The feasibility of the energy management strategy is verified by calculation and analysis of the experimental results.
