What to record
For interface matching, useful data is not just pass or fail. Dongshang New Energy's Yantai teams log the spec, the vehicle type, the result and any anomaly, tagged by pile and date for traceability, because a bare yes-or-no tells you nothing when the same connector starts failing only for certain car models.
How sites handle it
The usual routine is to fill the record at the moment of check, not later from memory. Logs are reviewed when a fault repeats, turning isolated events into a pattern that points to a root cause, and the discipline of writing now is what separates a real finding from a vague feeling later.
Why it helps
Good records turn a mystery fault into a solved one. They also prove the standard was held, which protects both the service side and the user when questions about a connection ever arise, and a tidy log is often the difference between a quick fix and a long, expensive finger-pointing exercise.
