A battery management system (BMS) is an essential component of electric vehicles (EVs) and other devices powered by batteries. By controlling and monitoring its functioning, it ensures the battery pack's longevity, safety, and maximum performance. Since it stores the energy required for an electrical vehicle to operate, battery storage is the most crucial component of any electrical vehicle. Therefore, an effective battery management system is required to maximize a battery's output and guarantee its safe functioning. The "Electrical Vehicle Battery and Fire Protection Management System" project focuses on developing a comprehensive safety and monitoring system for electric vehicle (EV) batteries. Utilizing an Arduino Uno microcontroller, this system integrates various sensors to continuously monitor the health and performance of the EV battery. Key components include a current sensor for measuring current flow, a voltage sensor for tracking battery voltage levels, and a Dallas temperature sensor (DS18B20) to monitor the battery temperature. In case of abnormal readings such as high temperature or overvoltage, the system triggers a 5V relay to disconnect the battery and prevent further damage or potential fire hazards. A CPU fan is also integrated to help cool the battery when temperatures rise above safe levels. A buzzer provides an audible alert for the user in case of any critical conditions. The system displays real-time data on an LCD screen, offering an interface for monitoring battery conditions. By ensuring timely detection of critical issues such as overheating, this system enhances the safety and reliability of electric vehicle batteries, preventing potential fire hazards and maximizing the battery’s lifespan.
