Abstract :

The rapid adoption of electric vehicles (EVs) has increased the need for efficient battery management systems to ensure safety, performance, and longevity. Conventional EV battery monitoring systems often lack remote accessibility and real-time protection mechanisms. This research presents an IoT-based Battery Management System (BMS) integrating an ESP8266 microcontroller, solar panel, battery, current sensor, IoT cloud, and fire detection sensors. The system continuously monitors battery voltage, current, and temperature, providing real-time data to a cloud platform for remote monitoring. A fire detection module is integrated to trigger alarms and prevent catastrophic battery failures. The ESP8266 serves as the central controller, processing sensor inputs and managing charge cycles. Solar panel integration enables renewable energy monitoring and partial charging. Data is transmitted to the IoT cloud for visualization and alert notifications. The system employs intelligent thresholds f
