The Battery Management System (BMS) is a critical component in modern electric vehicles, ensuring the safe, efficient, and reliable operation of the battery pack. It continuously monitors key parameters such as voltage, current, temperature, and state of charge, enabling optimal performance while preventing overcharging, deep discharging, and thermal issues. In electric vehicles, the BMS not only safeguards battery health and extends service life but also supports energy balancing and communication with vehicle control systems. Its precise management contributes directly to enhanced driving range, improved safety standards, and overall vehicle efficiency.
