Charging and Discharging Control of Li-Ion Battery for Electric Vehicle Applications

This paper presents the detailed simulation and analysis of a battery charging and discharging control for electric vehicle (EV) application using proportional and integral control. A lithium-Ion battery model in MATLAB is considered for this study. The purpose of study is to perform a detailed analysis of the charging and discharging operation and observe the behavior of the key parameters of the battery. To realize these two voltages sources have been used, i.e., one is the battery itself and the other is the DC voltage source. The two different voltage source is feeding to a common load. The DC voltage source feeds the load when the battery is in charging mode. When the battery supply is available then it is discharging to feed the load and its control is designed to generate the reference pulses for DC-DC converter. The two scenarios have been simulated and results are recorded which shows the effective operation of charging and discharging of a battery source.
