Abstract

This paper presents the design and implementation of an IoT-enabled smart Battery Management System (BMS) for a 3S lithium-ion battery pack. The system employs three INA219 current/voltage sensors, SPDT relays, an ESP32 microcontroller, and a 16×2 LCD display to achieve real-time individual cell monitoring. Key battery parameters — voltage, current, State of Charge (SOC), and State of Health (SOH) — are computed for each cell and simultaneously displayed on a local LCD and a Wi-Fi hosted web dashboard. A fault detection mechanism identifies overvoltage, undervoltage, overcurrent, and cell imbalance conditions, triggering relay-based cell isolation and real-time alerts. The proposed system provides a low-cost, scalable, and practical solution for battery monitoring in Indian EV, solar storage, and UPS applications.
