Sriperumbudur, TamilNadu ---------------------------------------------------------------------***--------------------------------------------------------------------Abstract— The demand for electric vehicles is rising, which ultimately results in an increase in the number of charging stations. In this project, the vehicle is wirelessly charged via inductive coupling, and payment is made using RFID technology. This project helps tackle the issue of building independent charging stations. Instead, this system can be incorporated in places like malls where people tend to spend longer, and thus parking time can be efficiently converted to charging time. The technology known as wireless power transfer (WPT) employing inductive coupling has the potential to relieve people from obtrusive wires. Additionally, a person can use the RFID tag to pay for the charging costs of that vehicle through the Internet of Things-based collection system that is designed. The system determines if the user has enough money in their account before taking the necessary deductions and updating the balance. No human interaction is necessary for this system. Along with a DC motor that will serve as a gate opener, we also used IR sensors to check for open slots. To track the vehicles that were charged at the stations, a web application was also created.

trouble with wires and connectors is eliminated by the WPT approach, making it convenient. Wireless power transfer (WPT) allows electric vehicles (EVs) to recharge their batteries without using a physical connection to a charging station. This technology offers several advantages over traditional wired charging, including greater convenience and reduced wear and tear on the vehicle's charging port. By enabling wireless charging, WPT technology can help increase the adoption of EVs by reducing the hassle and inconvenience of plugging and unplugging cables and by providing a more seamless and user-friendly charging experience. Additionally, WPT technology has the potential to increase the range of EVs by enabling dynamic charging while driving or parked, reducing the need for frequent stops at charging stations.

Keywords— Wireless Power Transfer, IoT, RFID, Smart Parking System, Android Application

RFID is used to make payments easier and safer. The self- operated gate at entry and exit is implemented using an IR sensor and a servo motor. Electric vehicles can be controlled using an Android application, which makes parking accurate.

1. INTRODUCTION

2. LITERATURE REVIEW

New technologies are always being developed in the field of technological innovation to make living easier. To charge electric vehicle, we still rely on the classical and conventional wire system. Wired charging systems has problems like when numerous electric vehicles are being charged at once, the traditional wiring system becomes a mess. They need bulky charging connectors and cords. Additionally, the charger needs to be manually linked. Lethal electric shocks could be caused by a short circuit or by the insulation of the charging cable failing because of conditions like high temperatures, ground contact, or the charging device itself.

M. Ahmed and O. O. Khalifa introduced a distinctive approach to wireless charging in their work titled "Wireless Power Transfer for Electric Vehicle Charging." They conducted tests under different conditions, evaluating distance and alignment, and achieved an impressive efficiency rate of 90%. Emphasizing the critical role of coil design, their findings underscore the significance of optimizing this component [1]. Addressing parking-related challenges, Denis Ashok, Akshat Tiwari, and Vipul Jirge developed a "Smart Parking System using IoT Technology." By harnessing the power of the Internet of Things (IoT), their system creates a wellorganized parking environment. Users are seamlessly directed to available parking spaces through illuminated indicators, eliminating the need for time-consuming searches. The system's automated nature also reduces labor requirements, enhancing efficiency [2].

To reduce charging time huge number of batteries can be employed, or the depleted batteries can be swapped out for the charged batteries as needed. The batteries, however, have their own set of issues. The batteries are expensive initially, hefty, and have a short lifespan. Future advancements in energy storage technology might make it possible to solve these issues. The WPT is yet another approach that might be used to get around the batteries' issues. Moreover, the manual plugged in charging systems'
