Fuzzy Power Management for Low Carbon Footprint Vehicles

Abstract

Currently, Hybrid Electric Vehicles (HEVs) are gaining traction in the market due to their low or zero carbon footprint. In this study, the power management of a Fuel Cell (FC) and Battery Electric Vehicle (BEV) using Fuzzy Logic Control (FLC) is investigated. Due to its sensitivity and low power density, the FC is used in parallel with a battery that serves as a storage element during regenerative braking periods. The DC link voltage is regulated via a control loop associated with the battery. However, a current regulation loop is used in conjunction with the FC to condition its power flow. The simulation results obtained using MATLAB/Simulink confirm the effectiveness of the proposed fuzzy energy management strategy. Additionally, the presented results demonstrate the ability of FLC to provide convenient power sharing between the utilized power sources without exhausting any source.
