A Smarter Energy Management System for Lithium-ion Battery and Super Capacitor Based Hybrid Energy Storage System

The electrical energy storage system is still the tailback for the commercialization of many electrical appliances. The battery storage system (BSS) has a high energy density but lower power density, and vice versa in case of the super capacitor storage system (SCSS). In this work, a hybrid energy storage system (H-ESS) with smart energy management system (EMS) is designed. The proposed EMS is based upon fuzzy logic that controller smartly distribute the power between BSS and SCSS depending upon the state of charge (SOC). This technique reduces the stress (high value current) of BSS during the challenging condition to prolong its life. The methodology is simulated on MATLABTM Simulink 2019. The simulation and comparative analysis with other EMS techniques have been carried out and the results showed that the smart EMS reduces almost 17% stress on BSS. This technique can be used to design EMS for other electrical appliances such as electric vehicles, electric wheelchairs, smart grid system, etc.
