摘要

The appropriate design of an energy management system (EMS) is crucial in fuel cell hybrid electric vehicles (FCHEVs) as it must ensure an efficient coordination of the multiple energy sources including the fuel cell (FC), battery, and super-capacitor (SC). This paper presents an up-to-date and extensive review of EMS strategies, focusing on RL-based methodologies and their application on new powertrain architectures. RL is identified as a promising technology that could be used to implement intelligent and adaptive control solutions that would also be energy efficient for FCHEVs. The review focuses on four main aspects: (1) powertrain configurations adopted for FCHEVs, (2) reinforcement learning techniques, parameters, and performance measures, (3) the use of multi-objective optimization for EMS design, and (4) datasets and simulation cycles applied in the studies being reviewed. Special focus is placed on the ability of the RL framework to learn dealing with conflicting objectives. These insights aim to guide researchers in advancing next-generation EMS for FCHEVs.
