WIRELESS ELECTRIC VEHICLE CHARGING USING INDUCTIVE COUPLING

The goal of the article "Wireless Electric Vehicle Charging Using Inductive Coupling" is to create a frictionless, effective, and secure electric vehicle (EV) charging system. Conventional plug-in charging techniques require direct physical contact, which frequently results in issues like connector wear, the potential for electric shock, and user inconvenience. This project uses the idea of Inductive Power Transfer (IPT), a method that wirelessly transmits electrical energy between two coils separated by an air gap using magnetic fields, to get around these restrictions. A transmitter unit and a receiver unit are the two primary components of the system's architecture. Powered by a DC source and managed by an Arduino Uno microcontroller, the transmitter coil produces an alternating magnetic field. The receiver coil, mounted under the vehicle, captures this magnetic flux and converts it back into electrical energy for battery charging. To improve safety and efficiency, infrared sensors are used to detect vehic le presence, activating only the corresponding transmitter coil. A relay driver circuit ensures that energy is transmitted only when necessary, reducing wastage and preventing overheating.
