Abstract
Hydrogen fuel cell vehicles represent a critical direction in the development of clean energy vehicles, where energy management strategies play a key role in determining system efficiency and economic viability. This study focuses on optimizing the energy management strategy for hydrogen fuel cell vehicles to enhance overall system performance and reduce operational costs. By constructing a hybrid power system model that integrates a fuel cell, battery pack, and electric motor, a combination of dynamic programming algorithms and adaptive fuzzy logic control is employed to achieve precise energy distribution under various driving conditions. The results demonstrate that the proposed optimization strategy can significantly improve system efficiency by approximately 8% and reduce hydrogen consumption by about 12% in typical driving cycles. Moreover, the strategy exhibits superior adaptability under complex conditions, along with excellent stability and robustness. A major innovation of this research lies in incorporating adaptive control theory into the field of energy management and experimentally validating its effectiveness, thereby providing significant reference for the practical application of hydrogen fuel cell vehicles.
