On the transmission side, energy is harvested using a solar panel and a wind turbine and then regulated through a charging circuit. A PIC microcontroller monitors the power input from multiple voltage sensors and controls a MOSFET driver to regulate energy transfer via a transmitter copper coil. The system also includes an LCD display, LED indicators, a reset button, and a crystal oscillator for system control. Control buttons are used to drive the vehicle.

On the receiving side, a receiving copper coil captures the transmitted power, which is then processed by a charging circuit to charge a Li-ion battery pack. A relay system manages power distribution, while a voltage sensor and temperature sensor provide real-time battery status monitoring. The Arduino microcontroller processes this data and displays it on an LCD screen, along with indications from an LED indicator and an alert system using a buzzer. Two buttons are used for fast and slow charging of vehicle battery. If the battery temperature is high then microcontroller turn ON the cooling fan to cool the battery.

The BMS is responsible for monitoring SOC, which indicates the available battery capacity, and SOH, which tracks the battery’s overall health and efficiency. This ensures the system operates optimally, prevents overcharging or overheating, and enhances battery lifespan.

Maximum Power Point Tracking (MPPT) is an electronic control technique used to optimize the operating point of renewable energy sources so that they deliver maximum possible power. Unlike mechanical tracking systems, MPPT dynamically adjusts the electrical parameters of the system to achieve optimal power transfer. In this project, a PIC microcontroller serves as the main control unit, continuously monitoring voltage levels from the solar panel, wind turbine, and rechargeable battery using voltage sensors.

Based on the measured parameters, the microcontroller intelligently controls the power flow to the load using Pulse Width Modulation (PWM) by using MOSFET, ensuring maximum energy extraction without compromising load performance. The system operates both under no-load and load conditions, and real-time voltage data is displayed locally on an LCD. Additionally, system parameters are uploaded to the ThingSpeak cloud platform through an ESP8266 Wi-Fi module, enabling remote monitoring and data analysis.

The hybrid solar–wind configuration improves energy availability, reduces dependence on conventional power sources, and ensures continuous power supply in regions with limited grid infrastructure. The proposed system is cost-effective, environmentally friendly, scalable, and suitable for standalone renewable energy applications. The embedded control logic is developed using Embedded C programming, making the system reliable and efficient for real-time operation.

Wind and solar energy have been used since the earliest civilization to grind grain, pump water from deep wells, and power sailboats. Wind-mills in pre-industrial Europe were used for many things, including irrigation or drainage pumping, grain-grinding, saw-milling of timber, and the processing of other commodities such as spices, cocoa, paints and dyes, and tobacco. Before the U.S. installed an infrastructure of electricity wires, both water-pumping windmills and small wind electric turbines (“wind chargers”) were vital to farming and developing the American Great Plains and west. In recent decades, the industry has been perfecting the wind turbine to convert the power of the wind into electricity. The wind turbine has many advantages that make it an attractive energy source, especially in parts of the world where the transmission infrastructure is not fully developed. It is modular and can be installed relatively quickly, so it is easy to match electricity supply and demand. The fuel – the wind – is free and plentiful, which eliminates or reduces the need to purchase, ship, and store expensive fuels. It is flexible – with the power generated, households use can use appliances, such as lighting and refrigeration, schools can use computers and televisions, and industries can access a reliable power source. Perhaps most importantly, the generator does not produce any harmful emissions in the process of generating the electricity, unlike many other generation sources.

Achieving a balance between power consumption and power production is a significant challenge today. The most effective solution is to utilize solar energy as efficiently as possible. A key problem in using solar energy lies in the need to position solar panels to maximize sunlight exposure. Fixed solar panels only receive optimal sunlight at certain times, but by dynamically adjusting the panel’s orientation, the solar energy generated can be increased. This project integrates a PIC microcontroller to track the sun’s position and automatically adjust the solar panel to maintain maximum energy absorption.

Wireless energy transfer, or wireless power, refers to the transmission of electrical energy from a power source to an electrical load without a physical connection. It is particularly useful where interconnecting wires are inconvenient, hazardous, or impossible. In this context, the wireless power transmission system differs from wireless communications, where the main concern is the signal strength. In wireless power transmission, efficiency is critical; a substantial portion of the energy transmitted must be received to make the system viable.

The system employs two self-resonating copper coils of the same resonating frequency. One coil is connected to the power source (transmitter), while the other is connected to the device (receiver). The electric power from the power source causes the transmitting coil to oscillate at a specific frequency, creating a magnetic field that induces oscillations in the receiving coil, which is tuned to the same frequency. This phenomenon, known as coupled resonance, is the principle behind Tesla’s wireless power transmission. The electricity is transmitted wirelessly through the copper coils, with the system designed to transfer power over a distance of about 10 cm.

A PIC microcontroller is incorporated into the system to regulate power flow, ensure efficient energy transfer, and control the vehicle’s movement. The microcontroller interfaces with the receiver circuit, which includes a rectifier and regulator, to convert the AC voltage to DC voltage. This DC power is then used to charge the EV battery, enabling the vehicle to operate efficiently using solar, wind, and wireless energy sources.
