Description
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 cells called a battery). The lithium-ion batteries can be used only in specified conditions called the safe operating area. Therefore BMS is necessary to monitor the battery state, ensure the safety of operation, and ensure long battery life. The battery characteristics to be monitored include 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 in a battery. To avoid loading of batteries, BMS protects the battery from:
- Deep discharge due to highly high discharge current.
- Over-voltage due to quick 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.
Protection: This BMS offers below mentioned protection of utmost importance.
- Overcharge Protection
- Temperature Sensor Protection
- Over-discharge Protection
- Electrostatic Protection
- Overcurrent Protection
- Dust Prevention
- Short Circuit Protection
- Cell Balancing Function
Applications: This protection board is widely used in 18650 Li-ion battery packs and offers multi-scenario applications.
- Electric tools
- Electric Vehicle E-Bicycle / E-Scooter/Bike
- Battery backup systems
- Solar/Wind energy storage systems, Solar street lamps
