Abstract


The increasing adoption of electric vehicles has created a strong need for safer and more convenient charging solutions. Conventional wired charging methods involve direct physical connections, which may lead to connector wear, safety concerns, and user inconvenience. To address these limitations, this paper presents the design and implementation of a wireless electric vehicle charging system integrated with real-time monitoring and automatic protection features. The proposed system operates on the principle of inductive power transfer, where electrical energy is transmitted from a primary coil to a secondary coil without physical contact. An ESP8266 microcontroller is used as the main control unit due to its built-in WiFi capability, enabling Internet of Things (IoT) based monitoring. The INA219 sensor is employed to measure voltage and current during the charging process. These parameters are continuously monitored and displayed on a 16×2 LCD for local observation, while the same data is transmitted to a mobile device through an IoT platform for remote access.

To enhance safety and battery life, an automatic power cut-off mechanism is implemented. When the battery voltage reaches a predefined threshold, the system disconnects the charging supply to prevent overcharging. The developed prototype demonstrates a compact, low-cost, and efficient wireless charging solution with smart monitoring capability. This work can contribute to the development of intelligent and automated EV charging infrastructure in the future.
