Hydrogen fuel cell vehicle solid-state hydrogen storage thermal management system based on digital twinning

Abstract

This invention provides a solid-state hydrogen storage thermal management system for hydrogen fuel cell vehicles based on digital twins, belonging to the field of new energy vehicle energy management technology. It includes: constructing a first data set; a vehicle thermal management operation status acquisition module, used to construct a second data set after the first data set; a digital twin modeling and health status prediction module, used to construct a heat-mass-reaction coupled digital twin model, and simultaneously, based on the first and second data sets, construct the pulverization rate coefficient, effective hydrogen storage capacity decay coefficient, and heat transfer performance degradation coefficient of the metal hydride material; and a collaborative optimization control and risk suppression module, used to construct a comprehensive health risk coefficient. This invention can reduce additional heating energy consumption while ensuring hydrogen supply stability and improving the overall vehicle thermal energy utilization efficiency; at the same time, by suppressing pulverization, slowing capacity decay, and improving heat exchange conditions, it effectively extends the service life of the hydrogen storage tank.
