Real-time implementation of battery management system with different charging approaches

Lithium-ion batteries (Li-ion) are the first option in applications that demand energy storage devices due to their high capacity, high depth of discharging, high energy density, long life cycle, no effect memory, and low self-discharge capability. Li-ion of necessity must be controlled in anticipation of an operation to be in a safe situation and get the best performance, so it must be utilized battery management system (BMS). BMS functionality monitors, control, and protects the battery pack from over-discharge, active balancing cells, and over-temperature. This paper utilized BMS to compare several charge methods to validate an efficient approach for maintaining battery performance. Proposed state I multi-stage current (MSC) based on Fuzzy Logic Controller (FLC) depending on the state of charge (SoC) as input for specifying the charging current as FLC output. State II, based on FLC, considers the temperature as a factor with SoC in specifying charging current. The state II charge method prefers because the rising temperature during the charging process reduces other charge methods, preserving the battery performance and life cycle.
