Electric Vehicle BMS with Fire Safety System

This project presents the design and implementation of an IoT-enabled Battery Management System (BMS) with integrated fire protection for electric vehicles. The system employs an Arduino microcontroller to monitor critical battery parameters such as voltage, current, and temperature in real-time. In addition, smoke and flame sensors are integrated to detect hazardous conditions. When abnormal situations like overheating, smoke, or fire are detected, the system activates an alarm, disconnects the motor through a relay, and triggers a fire extinguisher mechanism to prevent accidents. Furthermore, IoT connectivity via Wi‑Fi enables remote monitoring, data logging, and real-time alerts to users, ensuring enhanced safety and proactive maintenance of e-vehicles. The proposed system is low-cost, scalable, and capable of improving battery safety and vehicle reliability.
