Summary:The increasing Electric Vehicle (EV) market is driven by the desire for more efficient and reliable approaches to recharge EV batteries. Among various charging methodologies for EVs, Wireless Power Transfer (WPT) has gained more attention from EV users due to its features such as safety, low maintenance, comfort, automated operation, and reliability. The innovative WPT method replaces the conductive charging system while maintaining a similar power rating and efficiency. Numerous strategies have been devised to enhance the efficiency and reliability of the WPT model. The primary challenge in WPT is reduction in power transfer efficiency (PTE) as the gap between the coils is increased. Also, the improvement in the PTE depends on various design parameters of the WPT circuit. Therefore, this review article thoroughly investigates recent significant research literatures that explains WPT technology and tailored towards enhancement of PTE. The investigation is carried on various coil configurations, converter topologies and different critical factors to improve PTE such as impedance matching, compensation techniques. Moreover, the research gaps in WPT technology and future scope suitable for static, quasi-dynamic, and dynamic charging methods are presented. This research can play a crucial role in assisting developers in selecting an optimal design to enhance the WPT system.
