Description
Summary:In order to enhance the efficiency, extend the service life, and minimize hydrogen consumption of the fuel cell hybrid power system (FCHPS), an adaptive power allocation method considering stack operation performance is proposed. The method utilizes the minimum instantaneous optimization of equivalent hydrogen consumption to achieve power distribution between fuel cells and lithium batteries. Additionally, a power adaptive allocation method is proposed to address performance inconsistencies in PEMFC systems, effectively reducing operating pressure for improved service life and overall system efficiency. This approach ensures stable and efficient operation of high-power vehicle fuel cell hybrid power systems.
