For bulk-order DC connector reviews, do not sample only one vehicle or one document. Use risk-based sampling by model, batch, and exception risk, and document every check with vehicle charging records, equipment specifications, fault codes, and site-capacity assessments. If similar discrepancies recur, expand sampling or suspend release to avoid incompatibility between vehicle connectors, communications, or grid conditions and local facilities. The boundary remains clear: connector appearance alone cannot guarantee that all public chargers will be usable.
