Solar Wireless Electric Vehicle Charging System: A Review

Abstract

Pollution is one of the big problems in the present condition. Road transport currently accounts for 20-30% of urban air pollution. Electric Vehicles are a better alternative to curb the ongoing pollution. It is vital to make amendments in the battery charging process of Electric Vehicles (EVs) to attain greater reliability. Electric Vehicles battery charging can be done by plug in charging at charging station or by Wireless Charging System (WCS). This paper presents the solution for Battery charging of EVs by wireless charging system from renewable energy source (Solar PV System) and prepare a prototype working model of static wireless charging system. The principal element of wireless charging is to transmit power by an electromagnetic field across the space. Wireless power transfer is based on the principle of Faraday’s Law of Electromagnetic Induction. Wireless charging system can be implemented as static or dynamic wireless charging system. Static charging system can be implemented to charge the vehicle when it is in stationary mode and Dynamic charging system can be implemented to charge the vehicle even when it is in motion. By using inductive power transfer the power can be transferred from source to chargeable battery through the transmitter coil and receiver coil. This will not only increase the use of EVs but also make them efficient and reliable for large distances as well.

Introduction

The rising cost of fossil fuels and increasing environmental concerns have accelerated the adoption of electric vehicles (EVs). However, limitations in battery technology and charging inconvenience remain major challenges. To address this, the project proposes a solar-powered wireless EV charging system based on electromagnetic induction, eliminating the need for physical connections.

The system uses transmitter and receiver coils to transfer power wirelessly when the vehicle is near a charging station. Energy is primarily supplied by a solar PV system, with grid support as backup. The system supports both static charging (when the vehicle is parked) and dynamic charging (while the vehicle is in motion), which can improve efficiency and reduce battery size requirements.

The architecture includes components such as Arduino, sensors, coils, battery systems, and converters, enabling automated charging with minimal human intervention. The system detects vehicle presence using sensors and initiates charging automatically.

Compared to traditional plug-in charging, wireless charging improves safety, reduces energy losses, and enhances user convenience. Although it requires high initial infrastructure investment, it offers long-term benefits such as reduced pollution, lower fuel costs, improved efficiency, and support for sustainable energy use.

Overall, the system presents an eco-friendly, automated, and efficient solution for EV charging, contributing to the future of sustainable transportation.

Conclusion

Dynamic wireless charging system is a solution to charge the battery of EVs when the EVs is in motion and to reduce the time of charging. Time is saved by installing a static wireless charging system in garage, parking areas, traffic signals, home. Battery size and cost of EVs is reduced by using dynamic wireless charging system. It will be beneficial to consumers as well as environment, society and government. This concept provides a creative framework for quick charging for next electric automobiles. It is a charging element that practises solar-powered boards. Finding different source of energy is appealing from the standpoint of public transport in order to reduce the by-product of fossil fuels. Electric vehicles offer a way to reduce fossil fuel by products without using petrol. A remote charging framework might be a very practical solution to make the charging of electric vehicles more innovative, simple to use, and hassle-free. Solar roads can eventually replace conventional ones, but this will require a substantial initial investment With such a higher energy return and without having to replace the current infrastructure, the solar-powered roadway may very well be constructed for less money. The circle of sun-oriented street placement could function smoothly because it is expected that old streets will be maintained. Sun-oriented streets will address our nation\'s concerns about energy, pollution, coal contamination, waste contamination, and transportation When implemented, this novel remote charging method for electric vehicles will significantly reduce CO2 emissions. Comparing an electric vehicle to a gas-powered vehicle, carbon dioxide emission is reduced from 60 to 30 metric tonnes of discharge, or by 50%. This will help bring about a noble shift in nature while reducing environmental change.
