Dynamic Wireless Charging of Electric Vehicles Using RFID Protection

Abstract

Abstract: Electric vehicle (EV) development in transportation is growing rapidly, offering clean and sustainable transportation. The key challenges in the EV are high cost, limited range, battery recycling, charging infrastructure, and many more. Among these challenges, charging presents a double difficulty: limited availability and slow charging times. To address these challenges, charging infrastructure needs to be expanded, develop wireless charging technologies and advancements in battery technologies. In wireless charging there is static, charging while the vehicle is at rest, and dynamic, charging when the vehicle is in motion. EVs can be charged dynamically while they are moving, maximizing energy efficiency and reducing downtime for charging. In this paper a small-scale prototype for dynamic wireless charging with Radio Frequency Identification (RFID), is discussed. RFID integration enables convenient and secure user access and prevents energy theft by unauthorized charging. RFID tag is positioned at the start of the charging path. The dynamic charging system with RFID protection is shown to be feasible and effective by the prototype. The prototype has to demonstrate its capacity to safely and effectively charge EVs in real time while reducing the possibility of unwanted access or energy theft.
