Analysis the performance of Energy Transfer System (ETS) for EV battery charging method using non-isolated SEPIC converter-based CCCV control

Electric vehicle charging stations (EVCS) are in extremely high demand due to the advancement of EVs. To fix the insufficient charging stations issues vehicle to vehicle (V2V) charging method has been proposed. The energy transferring, battery cycles, and the state of battery depend on modeling the capacity estimation of batteries. In this research work, a practical Energy Transfer System (ETS) for lithium-ion battery-powered electric vehicle (EV) charging method is proposed. The proposed ETS includes a portable charger with a non-isolated SEPIC converter that can be simply set up as Constant Current/Constant Voltage control (CCCV) based PID controller and to optimize the target in accordance with SOC, battery voltage, and current. The proposed converter method controls the charging voltage and it’s current with a CCCV control. By altering the switch’s gating pulse duty cycle using a PWM technique, the dc voltage output will be regulated in a CCCV control mode, which charges the EV battery. The controller circuit determines the required duty ratio value utilizing input from mistakes produced by comparing the reference and measured output values. The proposed charging method is simulated using MATLAB/ Simulink software and is successfully executed for the V2V energy transfer system (ETS).
