A typical BMS consists of: Battery Management Controller (BMC): The brain of the BMS, processing real-time data. Voltage and Current Sensors: Measures cell voltage and current. Temperature Sensors: Monitor heat variations. Balancing Circuit: Ensures uniform charge distribution. Power Supply Unit: Provides energy to the BMS components.
Some other functionalities that can be in the BMU are interlock functionality or the real time clock and vector management system for the software. BMS Software Architecture: The battery management system architecture has different layers that abstract different parts of hardware.
One of the key functions of a BMS is cell balancing, which ensures that each cell in a battery pack is charged and discharged uniformly. Cells in series often exhibit slight differences in capacity, causing certain cells to overcharge or undercharge.
Power Control and Protection The BMS is equipped with power control circuitry that protects the battery pack from dangerous conditions such as overvoltage, undervoltage, overcurrent, and temperature extremes.
