The battery management system (BMS) project aims to develop and implement a comprehensive solution for monitoring and managing lithium ion battery packs. The system uses an Arduino as the primary controller, as well as a variety of sensors and gadgets, to measure and regulate various battery parameters. Its primary goal is to improve both the effectiveness and the security of battery-powered vehicles (EVs) with revolutionary Internet of Things (IoT) technology. Charge monitoring and fire prevention are among the key characteristics. Real-time data collection and analysis assure optimal charging conditions, extending battery life and increasing energy efficiency. Furthermore, sophisticated fire safety systems use sensors and clever algorithms to detect anomalies or overheating during charging, allowing for the rapid deployment of fire suppressants or power cutoffs to reduce dangers. This dual approach prioritizes both performance optimization and safety, fostering a secure environment for EV charging. Seamless connectivity among EVs, charging infrastructure, and a central monitoring system, facilitated by IoT, enables data analytics, remote monitoring, and prompt emergency responses. This project seeks to advance electric mobility by integrating charge monitoring and fire protection within a unified IoT framework, safeguarding against potential hazards and prolonging EV component longevity, thus encouraging broader adoption of sustainable transportation.
