Dissipative and Non-dissipative Cell Balancing SoC Constant Current, Voltage Charging of Li-Ion Battery for EV Application

In this paper, dissipative and non-dissipative comparative analyses of five cell balancing SOC constant current charging constant voltage charging of Li-ion batteries are introduced. Li-ion batteries are generally used in small-scale household electrical appliances, E-cars, automobiles, streetlights, aerospace, navigation lights, mobile phones, laptops, etc., over-discharge and overcharge may diminish their lifecycle. A good Battery Management System (BMS) is required to address this difficulty since the energy storage cells are linked in series. The battery bundle’s cells’ responsibility and performance can be improved. The three basic components of the BMS are balancing, management, and protection. The most crucial aspect of the three is balancing. Cell unbalancing occurs as a result of continuous charging and discharging in the battery system. Proper cell balance can increase battery life. SoC charge-controlled Li-ion batteries with 100 V nominal battery voltage and 50 Ah rated capacity are evaluated in MATLAB/Simulink using a battery bank consisting of five cells. According to the findings, the non-dissipative balancing of cells strategy outperforms the dissipative balancing strategy for lithium-ion batteries.
