“…The different design options provide more possibilities for achieving efficient power transfer. Studies such as [3,4,6,7,[49][50][51][52][53][54] discuss and compare the design and features of various coils for the transmitter and receiver pads to an extensive degree. Structural and design features of the transmitter and receiver pads for near-field WPT methods that use inductive coupling can be loosely translated for those that use electric fields to couple the GA and VA, such as CPT.…”

This study compiles, reviews, and discusses the relevant history, present status, and growing trends in wireless electric vehicle charging. Various reported concepts, technologies, and available literature are discussed in this paper. The literature can be divided into two main groups: those that discuss the technical aspects and those that discuss the operations and systems involved in wireless electric vehicle charging systems. There may be an overlap of discussion in some studies. However, there is no single study that combines all the relevant topics into a guide for researchers, policymakers, and government entities. With the growing interest in wireless charging in the electric vehicle industry, this study aims to promote efforts to realize wireless power transfer in electric vehicles.

“…Compared to conventional power transfer, power loss in wireless charging is approximately 7-12% higher. Additionally, the distance over which a wireless charger may transmit using electromagnetic induction and/or magnetic resonance is constrained [56][57][58][59]. This is a significant hurdle for manufacturers, particularly in the case of SUVs and LCVs possessing a high specific ground clearance as also for automatic design [60].…”

Electric vehicles could be a significant aid in lowering greenhouse gas emissions. Even though extensive study has been done on the features and traits of electric vehicles and the nature of their charging infrastructure, network modeling for electric vehicle manufacturing has been limited and unchanging. The necessity of wireless electric vehicle charging, based on magnetic resonance coupling, drove the primary aims for this review work. Herein, we examined the basic theoretical framework for wireless power transmission systems for EV charging and performed a software-in-the-loop analysis, in addition to carrying out a performance analysis of an EV charging system based on magnetic resonance. This study also covered power pad designs and created workable remedies for the following issues: (i) how power pad positioning affected the function of wireless charging systems and (ii) how to develop strategies to keep power efficiency at its highest level. Moreover, safety features of wireless charging systems, owing to interruption from foreign objects and/or living objects, were analyzed, and solutions were proposed to ensure such systems would operate as safely and optimally as possible.

“…Achieving an optimum coil geometry, which maximizes the PTE of an IPT system, requires proper selection of numerical value for the FoM parameter (i.e., P scf ). Besides influencing the system's PTE the design parameter P scf , based on (19), affects the coil ac ohmic resistance, which directly impacts the coil's physical size and R L O . To investigate the Fig.…”

“…their uniform magnetic field [14], can provide a large inductive coupling in comparison with spiral coils [6], [9], [14]- [17]. Examples of such systems include high-voltage battery charging [11], [18], [19] and WPT through-metal-walls [20]- [22]. It should be noted that selecting the coil topology is mainly influenced by the application's spatial restriction.…”
