IoT Enhanced Dual Battery Pack Management System: Ensuring Safety and Continuous Power in Electric Vehicles

This research work proposes an innovative Battery Management System (BMS) aimed at enhancing the safety and efficiency of electric vehicles (EVs). The BMS incorporates two battery packs: a primary pack that supplies power during operation and a secondary backup pack that activates when the primary pack is depleted. The system utilizes dual voltage sensors to continuously monitor the voltage levels of both battery packs, ensuring optimal power balance and performance. A temperature sensor is integrated to measure battery temperature, triggering a cooling fan when temperatures exceed a predefined limit, thereby mitigating the risk of overheating. Furthermore, a flame detection sensor is included to identify potential fire hazards, automatically shutting down the EV and sounding an alarm when fire is detected. Real-time data on voltage and temperature is displayed on an LCD screen, while IoT connectivity facilitates remote monitoring and management. This BMS not only aims to prolong battery life through effective management but also prioritizes user safety through proactive fire detection and thermal management.
