“…Coupling could be improved in this design compared with a single ferrite bar. Hariri et al [93] present a circular pad design that takes the effect of the magnetic core and the conductive shielding layers. Moreover, they proposed the Pareto optimality algorithm to maximise the coupling factor and the quality factor for the coils of the dynamic wireless EVs charging system.…”

One important technique of WPT technology is magnetic resonant coupling (MRC) WPT. Based on the advantages of MRC WPT, such as safety and high power transfer efficiency over a long transmit distance, there are many possible applications of MRC WPT. This paper provides a comprehensive, state-of-the-art review of the MRC WPT technology and wireless charging for electric vehicle (EV). A comparative overview of MRC WPT system design which includes a detailed description of the prototypes, schematics, compensation circuit topologies (impedance matching), and international charging standards. In addition, this paper provides an overview of wireless EV charging including the static wireless EV charging and the dynamic wireless EV charging, which focuses on the coil design, power transfer efficiency, and current research achievement in literature.

“…Some previous works endeavored to maximize the coupling coefficient [3]. Some tried to strike a balance among multiple objectives [4][5][6]. For most IPT systems, the latter, i.e., multiobjective optimization of the coil assemblies, is of more practical value as a practical IPT system is usually subject to various constraints.…”

“…Both analytical methods and numerical methods, e.g., finite element analysis (FEA) [3][4] and the finite-difference time-domain method (FDTD) [7][8], are useful tools for performance evaluation. The former is based on simplifications and usually restricted to certain types of systems [5]. By contrast, the latter is universally applicable and highly accurate provided that precise parameters are assigned to the model.…”

Energy efficiency and leakage magnetic field (LMF) are two important issues in electric vehicle inductive chargers. In this work, the maximum achievable coil efficiency and the corresponding LMF strength are formulated as functions of hardware parameters, and figure of merits (FOM) are proposed for assessing the efficiency and LMF performance of the coil assembly pair. The impacts of the coil assemblies’ geometric parameters on both FOMs are examined with the aid of finite element analysis (FEA), and measures to improve the FOMs are extracted from FEA results. A coil assembly pair is manually optimized within given dimensional limits. Compared with the initial design, the optimized one achieves higher efficiency and lower LMF strength while consuming less copper. The performance improvement is verified by FEA results and experimental data measured on an 85 kHz electric vehicle inductive charger prototype. The key measures for coil assembly optimization are summarized.
