Abstract: This paper presents the development of an IoT-based Battery Management System for real-time monitoring of battery parameters. The proposed system continuously measures battery temperature and voltage using appropriate sensors interfaced with an Arduino Uno microcontroller. The sensed data is uploaded to the Thing Speak cloud platform for real-time visualization and remote monitoring. A threshold-based buzzer alert mechanism is implemented to provide immediate warning during abnormal temperature rise, ensuring battery safety. The temperature sensor used in the system provides an accuracy of ±0.5 °C. The cloud update interval is set to 15 seconds, with an average communication latency of approximately 2–3 seconds. Experimental results demonstrate reliable data acquisition, stable cloud communication, and effective alert generation, making the system suitable for low-cost battery monitoring applications.

Keywords: IoT, battery management, electric vehicle, monitoring, sensors, cloud, analytics, efficiency, sustainability, performance.
