Enhanced Energy Management System for Hybrid Electric Vehicles using Cascaded Fuzzy Logic Controller

With the rising expense of traditional fuels, the
worldwide auto sector is rapidly turning to Hybrid Electric
Vehicles (HEVs) for their eco-friendliness, little upkeep
demands, and standing as green technologies. The Energy
Management System (EMS) is an essential part of HEVs, tasked
with effectively storing fuel and managing the flow of energy. Therefore, an exhaustive approach to the design, simulation, and findings of an EMS for HEVs that incorporates a Cascaded Fuzzy Logic Controller (CFLC) is proposed in this paper. A SEPIC converter is used for enhancing the battery's
manufacturing, while a boost converter improves the
supercapacitor's performance. Particularly, it has improved
reaction characteristics, with shorter rising and lowering times, leading to improved control of power. Further, CFLC is implemented to improve the performance of HEVs and promote their widespread use in the pursuit of environmentally friendly and effective transport alternatives. The BLDC motor is very suitable for HEVs because of its excellent efficiency, speed range, and low power consumption. In comparison to conventional converter designs, this work's high conversion efficiency of 90%, SOC of 60%, and voltage gain of 8V are proven by utilizing MATLAB/Simulink.
