Abstract

The rapid growth of electric vehicles (EVs) has increased the demand for efficient and safe battery management systems (BMS). This paper presents the design and implementation of an EV battery management system with integrated charge monitoring and fire protection using an STM32 microcontroller. The system continuously monitors battery parameters such as voltage, current, and temperature to ensure safe operation. A temperature sensor is used for real-time thermal monitoring, and protective actions are triggered when unsafe conditions occur. The system supports both fast and slow charging modes, optimizing performance while maintaining safety. In case of overheating, the system activates a relay-based isolation mechanism and alerts the user through a buzzer. Experimental results demonstrate accurate monitoring, efficient charge control, and reliable fire protection. The proposed system offers a cost-effective and scalable solution for EV battery safety and management.
