Abstract - Electric cars (EVs) are becoming more and more popular on the roads because of notable improvements in performance and driving range in recent years. Although conventional EVs are typically charged via cables, well-known manufacturers like Tesla, BMW, and Nissan are leading the way in the advancement of wireless charging technology, which does away with the necessity for large, unsightly wires. In addition to improving safety by preventing sparks during connection, this wireless, inductive charging method creates intriguing new opportunities for dynamic charging, which enables EVs to charge while they are moving. When completely implemented, this innovation should lessen the need for high battery sizes and remove the range anxiety associated with EVs. The world is aggressively pursuing and promoting this wireless charging revolution, with a focus on nations such as Korea, Germany, and the UK. An extensive literature study on wireless charging technologies for electric vehicles is included in this research. It explores the fundamental technological elements of wireless charging, such as communication protocols, coil design, and compensation topologies. The study examines a novel strategy for increasing charging power that involves using superconducting materials in coil designs and talks about how this can affect the effectiveness of wireless charging. Wireless charging safety issues are also covered, and a summary of the relevant standards is provided. The study offers an economic overview and analysis of the expenses related to different wireless charging setups. All things considered, this study advances knowledge about the developing field of wireless EV charging and emphasizes how revolutionary it can be for the electric vehicles industry.
Keywords: Electric vehicles (EVs), wireless power transfer (WPT), and wireless charging of EVs, Coils, Mutual inductance, Charging facility.
