“…The WPT depends on the detection of misalignment. Good acoustic arrangement, 143 electro-optic arrangement, 144,145 and RFID arrangement [146][147][148][149][150][151][152] are some of the misalignment techniques proposed across many studies. Optical methods for positioning are susceptible to impediments that are influenced by an atmospheric factor.…”

Considering a prospect where a driverless electric vehicle (EV) requires an automatic charging system that does not need a person to do anything. In this case, there is a need for a fully automated, fast, safe, cost‐effective, and reliable charging infrastructure that can be used for EVs and other EVs. This infrastructure must also be profitable and allow for quick adoption in electric transportation systems. Wireless charging methods may allow you to understand these characteristics. Wireless power transfer (WPT) is a future technology that offers flexibility, convenience, safety, and the capacity to be automated. Due to its high efficiency and ease of maintenance, resonant inductive wireless charging should get more attention in WPT techniques than other WPT methods. This literature provides an overview of the status of Resonant Inductive Wireless Power Transfer Charging technology, as well as a look at the current and prospects of the wireless EV industry. First, the article provides a brief history of wireless charging technologies, outlining the benefits and drawbacks. Then, the research assists in a comparative analysis of various types of WPT methodologies, control strategies, and compensation networks that have been done so far. The static and dynamic charging procedures, as well as their features, are shown. To increase charging power, a novel approach to the usage of superconducting materials in coil designs is examined, and their potential influence on wireless charging is highlighted. The detailed role and importance of power electronics, as well as the many types of converters utilized in diverse applications, are highlighted. The batteries and their management systems, as well as numerous WPT difficulties, are also discussed. Different trades are investigated, including cyber security economic consequences, health and safety, foreign object identification, and the effect and influence on the distribution grid. This article also highlights the opportunities and challenges associated with wireless charging systems. We anticipate that our effort will contribute to the advancement of WPT system research and development.

“…Detection of misalignment is the important part of the WPT system. In many studies various types of misalignment techniques proposed acoustical positioning [256], optical positioning [257,258] and RFID positioning [259][260][261][262][263][264][265].optical positioning methods are vulnerable to obstacles and effected by the surrounding environment. Acoustical positioning and RFID positioning effected by signal lack of multipath detection and non-line-of-sight.…”

“…The system applied eight radio nodes with four on the ground and the other four mounted underneath the secondary pad to sense the relative position between the primary and secondary coils. The radio nodes used by the system are based on an indoor ranging technique called wireless ad hoc system for positioning (WASP), which operates in 5.8-GHz ISM band with a bandwidth of 125 MHz and achieves a distance measurement error of about 0.2 m. Shuwei et al introduced an alignment system using sixteen reference RFID tags and two readers placed on ground and one tracking tag attached to the vehicle [14]. Although the radio alignment method is an alternative option for EV wireless chargers, it can increase the system complexity and thus result in a high-cost wireless charging system.…”

Wireless charging is a promising outlet to promote the electric vehicle (EV) industry due to its safe and noncontact manner. Wireless EV chargers require the secondary receiver coil to be well aligned with the primary station for efficient charging, which could require more of the driver’s time and attention when parking a vehicle. Therefore, this paper presents a magnetic alignment system to assist the EV driver during parking. The magnetic alignment approach uses the existing coil and frequency tracking control electronics of wireless chargers to detect the distance between the two coils while using 4 small auxiliary coils for direction and fine adjustment, leading to a cost effective detection method for coil alignment in electric vehicle wireless charging (EVWC). The testing results of a prototype show acceptable measurement correctness and the mean error for ten trials in range detection is within 0.25 cm at three different misalignment conditions (10.5, 15, and 20 cm). The positioning accuracy of coil alignment is within 1.2 cm for three different start positions with the auxiliary coils.
