| Abstract | ||
| Inductive wireless charging technology for electric vehicles (EVs) provides a simple and effective power transmission. Eliminating physical connections, improves user experience and minimizes maintenance. Optimizing system characteristics, including coil alignment, resonance frequency, and coupling factor, is critical for reducing power losses and increasing overall efficiency. This work provides a comprehensive review of an inductive wireless charging system for EVs, including major charging system components as transmitter and receiver coils, and resonant circuits. The inductive power transfer (IPT) model analyzes mutual inductance, coupling coefficient, and resonance frequency. Power transfer efficiency is determined using performance calculations that consider coil misalignment, air gap changes, and core material choices. Actual operating circumstances are used to determine overall power losses and provide optimization options for better system performance. Improved coil design, resonance adjustment, and power electronics optimization can boost system efficiency above 90%. This study offers useful insights into designing and optimizing inductive wireless charging stations for EVs, helping to promote sustainable and efficient charging options. | ||
