Automation has created a bigger hype in the electronics. The major reason for this type is automation provides greater advantages like accuracy, energy conversation, reliability and more over the automated systems do not require any human attention. Any one of the requirements stated above demands for the design of an automated device. Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to an electrical load without a conductive physical connection. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous, or impossible. The problem of wireless power transmission differs from that of wireless telecommunications, such as radio. In the latter, the proportion of energy received becomes critical only if it is too low for the signal to be distinguished from the background noise. With wireless power, efficiency is the more significant parameter.  A large part of the energy sent out by the generating plant must arrive at the receiver or receivers to make the system economical. The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. The project consists of two self resonating copper coils of same resonating frequency of about 100KHZ. One copper wire is connected to the power source (transmitter), while the other copper wire is connected to the device (Receiver).The electric power from the power source causes the copper coil connected to it to start oscillating at a particular (KHz) frequency. Subsequently, the space around the copper coil gets filled with nonmagnetic radiations. This generated magnetic field further transfers the power to the other copper coil connected to the receiver. Since this coil is also of the same frequency, it starts oscillating at the same frequency as the first coil. This is known as 'coupled resonance' and is the principle of Tesla.

The increasing adoption of electric vehicles (EVs) has created a growing demand for efficient, safe, and sustainable charging solutions. This project presents a solar-powered wireless charging system for electric vehicles that eliminates the need for physical connectors and promotes the use of renewable energy.

The proposed system utilizes a solar panel as the primary energy source, which charges a battery through a charging circuit. The stored energy is then converted into high-frequency AC signals using a pulse generator and MOSFET switching circuit. This alternating signal energizes a wireless power transmitting coil, generating a magnetic field.

On the receiver side, a wireless power receiving coil captures the transmitted energy through electromagnetic induction. The received power is processed using a regulated power supply (RPS) circuit to provide stable DC output suitable for charging an electric vehicle battery or mobile device.

This method offers several advantages including reduced charging cable dependency, improved safety, minimal wear and tear, and eco-friendly energy utilization. The integration of solar energy further enhances system sustainability by reducing reliance on conventional power sources.

Overall, the system demonstrates an efficient and contactless approach to EV charging, supporting the development of smart, green, and future-ready transportation infrastructure.
