Battery anomaly customer communication has to be traceable. When filing, use the battery anomaly communication sheet to link the fault symptom, the inspection progress, and the usage restrictions so that later staff can retrieve them by vehicle or order. Where the customer is blamed for how they operated the vehicle before any technical cause has been confirmed, the new-energy vehicle technical advisor should notify the affected roles and lock the current version. See this vehicle-import practice FAQ for the method of checking the related documents on battery anomaly customer communication. Once the change is closed, mark the old version as replaced and send the new battery anomaly communication sheet to all users.
