A critical review on inductive wireless power transfer charging system in electric vehicle

Abstract

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.
