The Battery Health and Recycling Traceability Intelligence System is designed to monitor and manage the overall performance, safety, and lifecycle of lithium-ion battery packs using an ESP32 microcontroller. The system continuously measures important battery parameters such as voltage, current, and temperature using INA219 and DS18B20 sensors. Based on the monitored temperature, an automatic cooling fan control mechanism is activated through a relay to maintain safe operating conditions. The system also provides automatic charging control, charge/discharge state detection, and real-time parameter display on an LCD with I2C interface for effective battery monitoring. In addition to monitoring, the system incorporates intelligent battery analytics such as State of Charge (SOC), State of Health (SOH), and Remaining Useful Life (RUL) calculations to estimate battery performance and predict end-of-life conditions. EEPROM memory is used to store charge and discharge cycle counts for maintaining battery usage history and recycling traceability. When the battery reaches its end-life condition or when the temperature value cross the set limit, the system alerts the user through a buzzer indication. This project improves battery safety, efficiency, maintenance, and recycling management, making it suitable for electric vehicles, renewable energy storage systems, and smart battery management applications.
