4. Communication instructions

4.1 RS232 Communication:

BMS can communicate with the upper computer computer through the RS232 interface to monitor various battery information at the upper computer terminal, including battery voltage, current, temperature, state, SOC, SOH and battery production information. The default port rate is 9600bps.

4.2 RS485 Communication:

With a dual RS485 interface, you can view the information of PACK, and the default port rate is 9,600 bps. If you need to communicate with the monitoring equipment through RS485, the monitoring equipment is the host, and polls the data according to the address, setting the address range from 1 to 15.

4.3 Code dial switch setting:

When PACK is used in parallel, different PACK can be distinguished by setting the dial switch on BMS, and the definition of BMS dial switch refers to the following table.

5. Precautions for use:

1) When connecting the battery lead, note not to misconnect or reverse connect. If the wrong lead is connected, it may cause damage to this circuit board, which should be re-tested again before use.

2) When assembly, the protective plate is careful not to directly contact the surface of the cell to avoid damage to the cell. Ensure the assembly.

3) In the process of use, pay attention to the lead head, soldering iron, solder and other components do not touch the components on the circuit board, otherwise it may lead to damage to the protection board.

4) The use process should pay attention to anti-static, moisture-proof, waterproof and other measures.

5) Please follow the designed parameters and the conditions of use during the use process, and do not exceed the relevant values in this specification, otherwise it may lead to damage to the protection plate.

6) After combining the battery pack and the protection panel, if there is no voltage output or no charge for the first time, please re-check whether the wiring is correct.
