What does the BMS usually do?
BMS stands for Battery Management System. It is an essential component of a battery system, including rack lithium batteries, and plays a crucial role in monitoring and controlling the battery's operation. The primary functions of a BMS include:
State of Charge (SOC) Monitoring: The BMS tracks the battery's SOC, which indicates the remaining capacity or energy level of the battery.
Voltage Monitoring: The BMS continuously monitors the voltage levels of individual cells or battery modules within the battery pack.
Current Monitoring: By measuring the current flowing into and out of the battery, the BMS accurately estimates the battery's charge and discharge rates.
Cell Balancing: As a battery ages or experiences variations in performance, individual cells within the battery pack may have slightly different capacities or voltages.
Temperature Monitoring: The BMS monitors the temperature of the battery cells to prevent overheating or operating under unfavorable temperature conditions.
Overcurrent and Overvoltage Protection
Fault Detection and Diagnostics: The BMS continuously checks for any faults or abnormal conditions within the battery system.
Communication and Data Logging: Many BMS systems offer communication interfaces to interface with external devices or monitoring systems.
