2. ABSTRACT The system enables efficient wireless power transfer for vehicle operation, utilizing solar energy as its primary source. It features a transmitter with a solar panel to charge a battery, which supplies energy to an inverter and transmitter coil for wireless transmission. On the receiver side, a receiver coil captures the energy, which is then converted to DC power by a rectifier and stored in a battery. Real-time monitoring and operational control are facilitated through an LCD display, providing updates on system performance. The integration of these components ensures a seamless and sustainable energy solution for various applications.

3. INTRODUCTION Wireless power transfer (WPT) systems offer a practical solution for efficient energy delivery without physical connectors, particularly for electric vehicles. Our system utilizes solar energy, where a solar panel charges a battery that powers an inverter and transmitter coil to wirelessly transfer energy. The receiver side captures this energy with a receiver coil, converts it to DC power using a rectifier, and stores it in a battery. Real-time monitoring is provided through an LCD display, ensuring effective system performance. This setup not only enhances convenience but also supports sustainability by leveraging renewable solar power for energy transfer.

4. OBJECTIVE Achieve reliable and efficient wireless power transfer from the transmitter to the receiver using solar energy as the primary source. Utilize solar panels to convert sunlight into electrical energy, promoting sustainability and reducing reliance on non-renewable power sources. Implement an LCD display for real-time monitoring of system performance, including battery status and energy transfer efficiency. Ensure seamless operation of the power transfer system with minimal physical connectors and maintenance requirements. Optimize the system design for maximum energy transfer efficiency and integration with renewable energy sources.

5. EXCITING SYSTEM Inductive charging pads are widely used for small devices, employing a primary coil in the pad and a secondary coil in the device to transfer power wirelessly. Resonant inductive coupling improves energy transfer range and efficiency by synchronizing the frequencies of the transmitter and receiver coils, often used in electric vehicle charging stations. Microwave power transfer uses microwave beams for long-distance energy transmission, though it remains mostly experimental and is used for large-scale applications like satellite power. Solar-powered systems integrate solar panels to provide power to WPT setups, effective for stationary use but limited by the need for direct sunlight. Existing systems encounter challenges with energy transfer efficiency, heat generation, and safety, particularly in high-power applications.

6. PROPOSED SYSTEM The integrates a solar-powered transmitter and a receiver to enable efficient wireless energy transfer for vehicle operation. On the transmitter side, a solar panel harnesses sunlight, which is stored in a battery and then converted to AC power by an inverter. This power is transmitted wirelessly through a transmitter coil. The receiver side captures this energy using a receiver coil, which is then rectified into DC power by a rectifier and stored in a battery. An Arduino Uno manages the system by monitoring voltage levels with sensors and controlling the DC motor, which represents the vehicle. An LCD provides real-time status updates, ensuring seamless operation and effective utilization of renewable energy.

Additionally, an LCD display provides real-time monitoring of system performance. This setup ensures efficient energy transfer and effective power management.

9. METHODOLOGY The methodology involves capturing sunlight with a solar panel and converting it into electrical energy, which is stored in a transmitter-side battery. This stored DC power is then converted to AC power by an inverter and transmitted wirelessly through a transmitter coil. On the receiver side, a receiver coil captures the transmitted AC power and a rectifier converts it back to DC power, which is stored in a receiver battery. Real-time monitoring is provided through an LCD display, ensuring efficient energy transfer and effective system management.
