“…These are applied to boost output and fix transmitter and receiver misalignment problems similarly to structural issues [314]. Additionally, each model's associated benefits and drawbacks are listed in a similar table [315]. The literature review assessed several WPT architectures' viability and magnetic coupling for automotive applications.…”

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.

“…Also, to the authors' knowledge, no study has explored solenoid coupler with WPT3 power level yet. The other classification defined in J2954 depends on ground clearance for each power level to accommodate various models of LDEVs: Z1-class (100–150 mm), Z2-class (140–210 mm), and Z3-class (170–250 mm) 3 , 14 . The actual perpendicular magnetic separation between the two sides (coil-to-coil distance or airgap) depends on the position of the transmitter pad whether it is under, flush, or above-ground, as indicated in Fig.…”

“…SR-Design L is chosen because of its features in term of weight, size and cost. The interoperability is measured based on performance indices: coupling factor ( k ), output power ( P ), and dc-dc efficiency ( η ), and stray EMFs 3 . These indices are estimated at perfect alignment as well as lateral and rotational misalignments.…”

“…These structures are divided into three types, Polarized structures, in which the flux components travel horizontally such as double-D (DD) pad and solenoid pad 2 . Structure with vertical flux components is called non-polarized such as rectangular and circular pads 3 . The third structure consists of multiple overlapped coils that are mutually decoupled and can generate both vertical and horizontal flux such as, bipolar and tripolar pads 4 .…”

Inductive power transfer (IPT) technology is a promising solution for charging the electric vehicles (EVs) by enabling an EV to charge its energy storage system (battery) without any connecting wires through magnetic coupling. This paper proposes a new receiver design named Hollow Solenoid receiver that is compatible with the standard double-D transmitter defined by the SAE J2954 standard. A deep design analysis for the proposed Hollow Solenoid receiver is presented to define the optimum design parameters for coil (inductances, number of turns, dimensions, wires, etc.) and ferrite core (dimensions, number, arrangement, etc.). Several WPT3 (11.1kVA) solenoid receiver (SR) designs were presented and analyzed based on efficiency, weight, size, volume, and cost. The performance of the proposed SR was compared with the global Double-D receiver (DDR) presented by the SAE J2954 standard under different lateral and rotational alignment and loading conditions considering coupling factor, transmission power and efficiency, and stray electromagnetic fields (EMFs). The entire IPT system including coils, compensation network, power converters, controls, and battery load was modeled and analyzed for both SR and DDR coils. The results reveal that the proposed SR is compatible with the global DD transmitter at different alignment and loading conditions and is able to transmit the desired power (11 kW) at an efficiency > 85%. Hollow SR design shows the highest efficiency and lowest size, weight, and cost compared to DDR and other designs.

In last few years we saw a significant development in the Electric Vehicle Industry. With this we needed faster, safer and more reliable charging systems. Wireless power charging seems to be the best option for solving most of the charging issues. One of the best methods WPT is Inductive Coupling. This technique is applicable for static and dynamic charging both. By using high frequency transformers, we can change the frequency of the supply AC which could save us a lot of energy. This energy could be enough to charge vehicle's batteries. This technique will have a big impact on charging time issues and reliability of electric vehicles in long distance.
