A Battery Management System (BMS) is a crucial component in battery-powered systems, responsible for monitoring and managing the battery's state, including its charge level, temperature, and health. It ensures the safe and efficient operation of the battery, preventing overcharging, overheating, and deep discharge. BMS is widely used in electric vehicles, renewable energy storage, and portable electronics. By optimizing battery performance and extending its lifespan, BMS plays a vital role in the reliability and sustainability of battery-powered systems.
