A BMS or protection board is any electronic control circuit that monitors, manages, and regulates the charging and discharging of any rechargeable battery (cell or combination of cell called battery). The lithium-ion batteries can be used only in specified conditions called safe operating area, and therefore BMS is necessary in order to monitor battery state, ensure safety of operation, long battery life. The battery characteristics to be monitored includes its state of charge, safe operating area, voltage, current, temperature, individual cell voltage, battery capacity and many more. The main task of battery management systems is to ensure the optimal use of the residual energy present in a battery. In order to avoid loading of batteries, BMS protects the battery from:

  • Deep discharge due to extreme high discharge current.
  • Over-voltage due to extreme fast charge.
  • Cell balancing in the case of multi-cell batteries by monitoring and regulating the charging and discharging of individual cells.
  • High Temperature
  • Short circuit of external load.


This BMS offers below mentioned protection of utmost importance.

  • Overcharge Protection
  • Temperature Sensor Protection
  • Over discharge Protection
  • Short Circuit Protection
  • Overcurrent Protection
  • Cell Balancing Function
