Battery management system with fuzzy logic controller for efficient lithium-ion usage

Recently, there has been a rise in renewable energy cause an increased demand for energy storage (ESS) devices, the most important of type which are batteries. Work has begun on studies to develop batteries in terms of performance, reduce cost and minimize time charging. Lithium batteries surpassed other than battery type through high energy density, low self-discharge, but to gain maximum performance and safety of the battery, and there must be a control unit named Battery Management System (BMS). BMS plants monitor and control the battery pack. In this paper, BMS was proposed in MATLAB/Simulink 2020a version to protect and managed the batteries from overcharging, discharging, overheating, and exercised cell passive balancing in addition to alluding to a charging method which depending on the State of Charge (SoC) and Temperature to specify the charging current, the proposed method based fuzzy logic controller (FLC). The results show that protection features were the best performance and the proposed charging method that maintains of the battery because the temperature increase during the charging process impacts the performance and life cycle.
