Abstract

This paper presents the design and simulation of a three-phase grid-connected fast-charging system for a 12 V, 75 Ah Nickel-Metal Hydride (NiMH) electric vehicle (EV) battery using MATLAB/Simulink. The proposed system integrates a three-phase active rectifier, a DC-link filter, and a buck–boost DC-DC converter. The control algorithm employs a two-stage Constant Current–Constant Voltage (CC–CV) protocol, with a PID based a closed-loop strategy that ensures stable and efficient charging. The system is designed for a maximum charging current of 75 A (1C rate) to ensure safety and battery longevity. The system is modeled in detail, incorporating realistic component parameters and a high-fidelity battery model. Simulation results demonstrate effective regulation of battery voltage at approximately 12.7 V, with initial charging current peaking at the targeted 75 A and the transitioning to a lower, stable current during the CV phase at 30 A. The State of Charge (SOC) profile confirms that the proposed system achieves rapid charging while maintaining voltage stability and minimizing ripple. These results validate the system as a reliable and scalable solution for high power fast-charging infrastructure and provide a foundation for further optimization and experimental validation.
