Functions of LiFePO4 Battery BMS (Battery Management System):
(1) Measurement of LiFePO4 battery terminal voltage
(2) Energy balance between single LiFeP04 cells
(3) Total battery voltage measurement
(4) Total battery current measurement
(5) SOC calculation: estimate the remaining power of the Lithium battery
(6) Dynamically monitor the working state of the LiFePO4 battery pack: prevent over charging or over discharging
(7) Real-time data display
(8) Data recording and analysis: maintain the reliability and efficiency of the entire battery operation
