The High Efficiency Wireless EV Charging System using Resonant Inductive Coupling is designed to transfer electrical power from a stationary charging unit to an electric vehicle without physical connectors. The system operates on the principle of resonant inductive coupling, where power is transmitted efficiently between a transmitting copper coil and a receiving copper coil tuned to the same resonant frequency. In the transmitter section, a regulated DC power supply provides a stable input voltage to the Microcontroller. This DC supply is fed to a DC–AC converter (inverter stage), which is controlled by a PIC microcontroller. The PIC microcontroller generates high-frequency PWM (Pulse Width Modulation) signals, which drive the switching devices (such as MOSFETs) in the inverter circuit. As a result, the DC input is converted into high-frequency AC. This high-frequency AC energizes the transmitting coil, producing a high-frequency alternating magnetic field around it. In the receiver section, the induced AC voltage is converted into DC using an AC–DC rectifier and further regulated through a boost converter to obtain a stable output suitable for battery charging. A PIC microcontroller continuously monitors the voltage and current of the receiving coil, and the measured values are displayed on an LCD for real-time observation. LED indicators are provided to show charging status and system operation. The use of resonant inductive coupling significantly improves power transfer efficiency, reduces transmission losses, and enables safe, convenient, and contactless EV charging. This system enhances reliability, minimizes wear and tear associated with wired charging, and supports the advancement of smart and sustainable electric vehicle infrastructure.
