Verification after Replacement
After a part is replaced for the Module or BMS Box, verify the function in the following way:
Wire module, BMS Box, and PCS to establish a system.
- Module and BMS Box must match.
- Ensure that the wires are connected properly.
Power on the system and check the LED status to ensure no fault.
(Optional) If a PCBA is replaced, connect the BMS Box to a host computer and check the version of firmware.
(Optional) If the firmware is earlier than the original one of the Module or BMS Box, upgrade the firmware to the original version or a later one.
Charge the system until the SOC reaches 100%.
Discharge the system until the SOC reaches 0%.
If the power cycle is completed successfully, it is recommended to charge the module to 30%SOC for storage.
