Qualified person

Event message:

  • Battery Stack Startup Failure

Explanation:

During the start-up process, the system may fail to complete the start-up process for reasons such as a pre-charging error, a contactor malfunction, or a battery condition that does not meet requirements, resulting in the battery stack not functioning properly. As a result, the system temporarily enters an error state, which is automatically cleared once the system has stabilized. If multiple errors occur in succession, the error is upgraded to a "Battery stack start restricted" error.

Corrective measures:

  • Access the system's historical events interface to review the specific error codes or direct causes recorded during this startup error (e.g., "Pre-charge timeout", "XX contactor controller error").

  • Investigate and resolve the problem based on the exact cause specified in the logs.

  • If the system transitions from a startup state to an error state, this error can be automatically corrected.
