Battery Management System (BMS) in electric vehicles is crucial for controlling battery behavior, as the battery is the heart of an EV.BMS manages the electronics of a cell or battery pack to ensure safe operational parameters for both the battery and user.Key functions of BMS include monitoring battery parameters like voltage, temperature, State Of Charge (SOC), State Of Health (SOH), and more.BMS can make key calculations on energy delivered, impedance, charge in Ampere per hour, and total charge cycles of the battery.Thermal management is essential for BMS to control battery temperature and optimize its performance, ensuring longevity and safety.BMS optimizes battery utilization to maximize the vehicle's range per charge without compromising power requirements.It handles functions such as charging control, overcharge protection, overheating protection, short circuit protection, and real-time data monitoring.BMS acts as the brain of the electric vehicle, managing most vehicle parameters to ensure battery and user safety.Overall, the BMS plays a critical role in the efficient and safe operation of electric vehicles.
