What is the function of the BMS battery protection board

Lithium battery protection board (also known as BMS, battery management system) is a circuit board used to protect lithium batteries. Its main function is to monitor and control the charging and discharging process of lithium batteries to ensure their safe and stable operation.
The functions of lithium battery protection board include the following aspects:
1. Battery charging protection: The lithium battery protection board can monitor the charging process of the battery. When the battery voltage reaches the set upper limit, the protection board will automatically stop charging
Electricity is used to prevent overcharging and protect the safety of the battery.
2. Battery discharge protection: The lithium battery protection board can monitor the discharge process of the battery. When the battery voltage reaches the set lower limit, the protection board will automatically stop discharging
Electricity is used to prevent over discharge and protect the safety of the battery. 3. Temperature protection: The lithium battery protection board can monitor the temperature of the battery. When the battery temperature exceeds the set safety range, the protection board will automatically stop charging and discharging to prevent overheating, thereby protecting the safety of the battery.
4. Balanced charging: The lithium battery protection board can monitor the voltage of each individual battery in the battery pack. When the voltage of a single battery is too high or too low, the protection board can redistribute the charge in the battery pack through balanced charging to maintain voltage balance between each individual battery and extend the battery’s service life.
5. Communication function: Some lithium battery protection boards also have communication function, which can exchange data and control with external devices (such as battery management systems, chargers, etc.) through serial port or wireless communication, achieving more accurate battery management and control. In short, the lithium battery protection board is an important circuit board that can monitor and control the charging and discharging process of the lithium battery, protecting the safe and stable operation of the battery. When using lithium batteries, it is important to use a reliable and stable lithium battery protection board to ensure the performance and lifespan of the battery.
