High-efficiency EV charging system using Zeta-Cuk converter with optimized MPPT and power management

Due to the growing demand for efficient and sustainable energy solutions for Electric Vehicles (EVs) powered by Brushless DC (BLDC) ‎motors, this work presents a high-efficiency EV charging system that integrates renewable energy through a high-gain Zeta-Cuk converter ‎and advanced power management. The converter boosts the low voltage from photovoltaic (PV) panels to a high DC bus level, ensuring ‎efficient energy transfer. To maximize power extraction an optimized Maximum Power Point Tracking (MPPT) method, combining the Ant ‎Lion Optimization (ALO) algorithm with an Adaptive Neuro-Fuzzy Inference System (ANFIS), is used. A storage battery and grid ‎connection are incorporated to manage surplus energy during periods of excess PV generation. Power flow between the grid, battery and ‎BLDC motor is coordinated via a bidirectional DC-DC converter controlled by a Proportional-Integral (PI) controller. The system is ‎validated through MATLAB/Simulink simulations, demonstrating a high conversion efficiency of 96.69% and a tracking efficiency of ‎‎99.21%, confirming its potential as a practical and eco-friendly solution for sustainable transportation‎.
