Work backward from the execution milestone for high-temperature power derating; a supplier's general response is only a lead. Identify who provides vehicle charging records, equipment specifications, fault codes, and site-capacity assessments, who reviews them, when they expire, and who approves an alternative if there is a discrepancy. This exposes issues before vehicle connectors, communications, or grid conditions become incompatible with local facilities. The conclusion remains subject to the rule that connector appearance alone cannot guarantee that all public chargers will work.
