Wireless EV charging station with IOT billing

The Wireless EV Charging Station with IoT Billing successfully demonstrates a smart and efficient approach for charging electric vehicles without the need for physical charging cables. The system works using inductive coupling technology, where electrical power is transferred wirelessly between transmitter and receiver coils. During testing, the prototype was able to charge a demo battery successfully with a coil separation distance of nearly 2 cm. The use of the ESP32 microcontroller along with the ThingSpeak platform enabled real-time monitoring and IoT-based billing functionality. The system continuously monitored charging activity and calculated billing information based on charging duration. The ultrasonic sensor helped in automatic vehicle detection, while the relay module controlled the charging operation automatically. The LCD display and GSM module improved communication and allowed users to monitor system status easily.   Compared to traditional wired charging systems, the proposed model provides better safety, less maintenance, and greater convenience for users. The project also demonstrates the practical use of wireless power transfer combined with IoT technology for smart monitoring and automated billing.   In the future, the system can be improved further by increasing charging efficiency, extending the charging distance, and integrating renewable energy sources such as solar power. Overall, the project presents a promising solution for future smart EV charging infrastructure and advanced transportation systems.
