Description
This product is a comprehensive battery management system (BMS) designed for 8-16 series-connected lithium-ion battery packs. It offers full compatibility between 15-celland 16-cell configurations—simply adjust the cell sampling wires to connect the 15th and 16th cells, then configure the cell count and total voltage protection parameters via the host computer software.
The BMS provides protection and recovery functions including:
Individual cell overvoltage/undervoltage
Total pack overvoltage/undervoltage
Charging/discharging overcurrent
High/low temperature protection
Short circuit protection
It complies with functional safety standards including IEC 62619 and UL 1973. The system enables: Accurate State of Charge (SOC) estimation during charging/discharging,State of Health (SOH) monitoring,Voltage balancing during charging and in static conditions.
Communication with the host device is achieved through RS485 interface. Parameters can be configured and data monitored via host computer software.
Note: Host computer baud rate is 19200.

Battery Management Systems (BMS) cannot be used in series.
The withstand voltage of the BMS power components is 100V.
If the battery module is assembled using long wires or long copper busbars, impedance compensation must be implemented in consultation with the BMS manufacturer. Failure to do so may affect cell consistency.
Connecting external devices to the BMS's external switch is prohibited. Technical consultation and confirmation are required for any such needs. The company will not bear any responsibility for BMS damage resulting from non-compliance.
During assembly, ensure the protection board does not directly contact the cell surface to avoid damage. All assemblies must be secure and reliable.
During use, prevent wire ends, soldering irons, solder, etc., from contacting components on the circuit board, as this may damage the board. Additionally, take precautions against electrostatic discharge (ESD), moisture, and water ingress.
Operation must adhere to the specified design parameters and usage conditions. Exceeding values stated in this specification may damage the protection board.
After combining the battery pack and protection board, if no output voltage is detected or charging is impossible during initial power-up, verify the wiring connections are correct.
The company reserves the final right of interpretation.
