Solar Powered Wireless Electric Vehicle Charging Station

The rapid growth of electric vehicles (EVs) has increased the demand for efficient, safe, and sustainable charging infrastructure. Conventional EV charging systems rely heavily on grid power and wired connections, which may lead to increased energy consumption, higher operational costs, and safety concerns such as electrical wear and spark hazards. To address these challenges, this project presents the design and implementation of a Solar-Powered Smart Wireless EV Charging Station with IoT Monitoring. The proposed system utilizes solar energy as the primary power source, ensuring clean and renewable energy utilization. A solar panel array configured in series-parallel combination supplies power to the system, which is regulated using a Maximum Power Point Tracking (MPPT) charge controller. The MPPT module acts as a smart DC-DC voltage regulator, optimizing power extraction from the solar panels while protecting the battery bank. A 12.6 V Battery Management System (BMS) is employed to safely manage charging and discharging of the lithium-ion battery bank, providing protection against over-voltage, undervoltage, over- current, and cell imbalance. Wireless charging is implemented using a wireless power transfer module based on electromagnetic induction. When a vehicle is placed on the charging platform, power is transferred wirelessly without physical connectors, improving safety, reliability, and user convenience. The system automatically detects vehicle presence using infrared sensors and initiates charging accordingly, minimizing energy wastage. An ESP32 microcontroller serves as the central controller, handling sensor data acquisition, control logic, relay operation, LCD display updates, and wireless communication. System parameters such as solar voltage, temperature, humidity, EV charging status, and street-light operation are monitored and displayed in real time using the Blynk IoT platform, enabling remote supervision. Additionally, an automatic solar-based street-lighting feature is incorporated to enhance energy efficiency during nighttime conditions.
