IoT-Driven Smart EV Charging System with Predictive Maintenance and Advanced User-Centric Features for Urban Heat Island Mitigation

The rapid adoption of electric vehicles (EVs) has raised the demand for efficient and smart charging infrastructure. This paper presents an IoT-based Smart EV Charging System that integrates a variety of sensors and components providing not only a seamless user experience but also predictive maintenance capabilities. The system incorporates advanced features for monitoring environmental parameters and controlling urban heat island (UHI) effects through water misting and fan systems. Key components include environmental sensors (DHT22, MLX90614, MQ-135, LDR, ZMPT101B), ADXL345 and power management units (INA219, TMP36, WattNode). The proposed system leverages ESP32 WiFi for remote monitoring and control with predictive maintenance based on sensor data to ensure reliability and efficiency. The RC522 RFID Module is also used for advanced user centric experience.
