Optimising Energy Management Strategies for Hybrid Electric Vehicles: To Improve Efficiency and Performance

In this paper, a new optimised energy management approach for a hybrid power system based on batteries and supercapacitors specifically intended for electric cars (EVs) is presented. The suggested approach makes use of optimal differential fatness to efficiently regulate the two energy sources’ power distribution according to load demand. The main goal is to meet the power requirements of a synchronous reluctance motor (SynRM) and maximise power quality by minimising current harmonics, which will improve battery longevity. The optimal adaptive differential fatness strategy that has been suggested has significant advantages over traditional strategies. It reduces battery current harmonics, minimises DC-bus voltage ripples and voltage overshoots, and minimises peak currents during acceleration and deceleration phases. By improving the power system’s ability to adjust to unforeseen fluctuations in load, the online updating strategy further increases the system’s robustness and efficiency. The proposed energy management system’s possible applicability to various power systems, such as those incorporating fuel-cell technology in hybrid electric vehicles, is discussed in the paper’s conclusion.
