RFID as an addition of wireless charging systems for electric vehicles

Abstract

Aim: The aim of this study is to review existing methods for wireless charging of electric vehicles and propose the most optimal option for implementing vehicle identification using RFID. This will ensure automated, secure, and convenient authorization and payment of electric vehicle owners during the charging process. Materials and Methods. To determine the most optimal wireless charging system, we conducted an analysis of modern research in this field. Based on this analysis, we selected inductive charging as the preferred method and proposed enhancing its standard functionality by integrating RFID and other sensors using the STWBC Qi series controller. Results. There are four main types of wireless charging systems: inductive energy transfer, capacitive energy transfer, rotating permanent magnet charging, and microwave and radio wave energy transfer methods. Among these, the induction method is the most effective. Additionally, wireless chargers can be equipped with a special RFID system to automate the payment process. Conclusion. Wireless charging offers a superior alternative to traditional wired charging systems in urban environments as it eliminates the need for additional infrastructure that occupies parking spaces. Inductive charging stations are the most preferable option when considering parameters such as price, performance, and quality. The “STWBC Qi” series controller not only facilitates RFID integration but also serves as a key component for controlling the inductive wireless charging system.
