Event E067
Qualified person
Event message:
Battery Group Enable but Inactive
Explanation:
The system has detected that a specific battery module in the pack is in the "Ready" state, but is not in operation. For safety reasons, the module's DC contactor did not close, thus isolating it from the system and preventing it from participating in the charging or discharging process.
This warning is for status notification purposes only and is intended to alert maintenance personnel to be aware of the faulty module.
Corrective measures:
Check the system warning interface or the battery module monitoring page to see which specific module (module number) is reporting this status.
Check the system warning interface or the battery module monitoring page to identify the specific, direct cause of the error that led to the module's isolation (e.g., contactor overheating).
Based on the specific error information obtained, perform a targeted inspection and repair.
Once the underlying error is rectified, the module automatically exits the isolation state, its DC contactor closes, and this alarm is automatically cleared.
