In this article, a comprehensive review of the WPT systems for electric battery charging focusing on inductive power transfer is presented. The basic WPT principles of electric battery charging is investigated.
The underlying method for such a power transfer is inductive power transfer (IPT), one of the fundamental techniques of WPT. However, there is no single "best" method for WPT—it largely depends on the specific requirements of the application. Each method has its merits and limitations and is suited for particular scenarios.
Wireless power transfer (WPT) is a promising technology that has the potential to revolutionize the present methods of power transmission. This paper aims to provide an overview of WPT, including its history, a comparative review of methods, and a review of recent papers about WPT.
The implemented inductive power transfer system encompasses several key components, such as the design of transmitting and receiving coils, a WPT charger, a charging circuit, an energy storage system, and measuring devices to monitor the SOC of the lithium-ion battery.
In the field of traditional power transfer methods, the energy is passed directly from the source to the load via conductive materials—metals, typically. This necessitates the use of physical connectors and adapters, leading to potential safety risks, maintenance issues, and a significant lack of flexibility.
A world where electric vehicles charge their batteries wirelessly while moving on the roads, where one's smartphone restores energy merely by being near a power source, and where isolated, off-grid sites receive power effortlessly from central hubs. This is the potential held by wireless power transfer.
