Event E068
Qualified person
Event message:
Battery Group Fault Isolation
Explanation:
The system detected that a specific battery module in the pack had a error (e.g., severe overtemperature, overcurrent, overvoltage) and was isolated to protect it by opening its DC contactor to take it out of service.
This warning is a resulting status message and is reported simultaneously with the specific error that caused the isolation.
Corrective measures:
Check the system warning interface for the specific battery module number that has been isolated.
Check the specific error message that appeared at the same time as the battery module isolation (e.g., Module XX severe overheating), which is the direct cause behind the isolation.
Ignore this warning and focus on troubleshooting and resolving the specific error that was reported at the same time.
Once the underlying serious error of the battery module has been fully rectified, the system will automatically exit the isolation state, the module will resume operation, and this warning will be automatically cleared.
