Description

Technical Field

[0002] Hydrogen fuel cell vehicles are the main direction of clean and low-carbon development of automobiles in the future due to their advantages of zero emissions, no pollution, and high volume power density. At present, hydrogen fuel cell vehicles are mainly electric-electric hybrid power systems composed of hydrogen fuel cell systems and power battery systems (lithium batteries).

In the prior art CN116101130B, a method and system for energy management of fuel cell vehicles is used to obtain the energy and time required for the vehicle to pass through a certain section of the road from the starting point to the end point based on the average vehicle speed information, vehicle weight information, rolling resistance coefficient, wind resistance characteristics, wind force and wind direction information, and altitude change information of each section between the starting point and the end point of the vehicle; although this method can achieve global optimization of economy, it will cause frequent load changes in the fuel cell, affecting the overall life of the fuel cell. In the prior art CN116278993A, a fuel cell vehicle energy management control method considering multi-objective optimization is provided. The present invention models the key power components of the whole vehicle and the mechanism of the vehicle fuel cell system, and establishes the fuel cell and power battery life decay estimation and equivalent hydrogen consumption model, and uses the Pontryagin minimum principle to optimize the multi-objective problem of fuel cell vehicle energy management. However, the establishment process of the multi-objective optimization method involves subjective weight selection, which will affect the optimality of the result. In CN117034666A, in the patents of fuel cell vehicle energy management methods, systems, media, equipment and terminals, the fuel cell voltage decay and power battery capacity decay degree are combined with the hydrogen consumption cost to establish a full life cycle operation and maintenance cost model, which will cause the fuel cell to frequently change load, which is not conducive to the life of the fuel cell. Therefore, the prior art has problems such as frequent load changes of fuel cells and subjective weight selection, which affect the life and use effect of the fuel cell. Summary of the invention
