IoT Based Electric Vehicle Battery Management System by Using Charge Monitor And Fire Protection

Abstract: This paper presents the development of an IoT-based Electric Vehicle Battery Management System with charge monitoring and fire protection. The main aim of this system is to improve the safety, performance, and life of the battery used in electric vehicles. In this system, important battery parameters such as voltage, current, and temperature are continuously monitored using sensors. The collected data is processed using a microcontroller and displayed on an LCD for local monitoring. At the same time, the data is sent to an IoT platform, which allows users to monitor the battery status remotely in real time. The system also includes safety features. If any abnormal condition such as high temperature, over-current, or low-voltage is detected, the system automatically takes protective actions. These actions include turning OFF the motor, stopping charging, activating a cooling fan, and giving alerts through LED indicators and a buzzer. This helps in preventing battery damage and reduces the risk of fire hazards. Overall, this paper provides a simple, low-cost, and effective solution for battery monitoring and protection in electric vehicles. It improves battery reliability, ensures safe operation, and supports efficient energy management.
