Abstract: Electric vehicle are gaining importance day by day because of the benefits it has over conventional vehicles. As a future response for Electric Vehicle (EV) charging practicality of Contactless Power Transfer (CPT) is being explored broadly for past couple of years. The primary snags in CPT are cost, range, misalignment tolerances and low power efficiency. By introducing Wireless Power Transfer (WPT) in EVs, the drawbacks such as charging time, range, and cost can be successfully moderated. WPT is a potential alternative in EV to overcome plug-in problems. This paper currently discusses about the recent technical advancements in EVs and problems faced by implementing WPT. With many recent advances in WPT makes it very desirable to EV applications, in both dynamic charging and stationary charging circumstances which eliminates the bulky, heavy battery requirements. This paper discusses about the 2 port and 3 port WPT mostly used for EV. MATLAB-Simulink Software and PSIM Software are used to analyze the WPT. Future technologies such as Wireless Electric Vehicle Charging Systems (WEVCS) such as “Vehicle to Grid (V2G)” charging systems are also discussed with comparisons among the existing technologies.
