Quality claims should be traceable from sample to after-sales case.

BEFORE ORDER

Agree on what “approved” means

Quality requirements should be written into the project scope, not inferred from a product photo.

• Approved application and configuration
• Required product and packaging labels
• Document set and language
• Sample-test acceptance record
• Commercial inspection or third-party requirements if applicable
• Warranty terms stated in the quotation or contract

BATCH

Keep the production batch identifiable

Define the identifier that connects supplied units, inspection evidence, shipment records, and future support cases. The exact traceability method must be confirmed for the project.

HANDOVER

Give dealers usable operating guidance

The handover pack should cover connection sequence, safe use, stop procedure, storage, limitations, and what evidence to collect if charging does not start. Final instructions must match the approved product configuration.

CASE

A support case needs six facts

Use a consistent intake structure so the issue can be reproduced and reviewed.

• Vehicle brand, model, year, and market version
• Charger operator, charger identification, and location
• Adapter batch or serial identifier
• Connection sequence and state of charge
• Ambient conditions and observed behavior
• Photos, video, and exact fault message

RESOLUTION

Separate product defects from compatibility exceptions

A charging issue may involve the adapter, vehicle, charger, operating sequence, firmware environment, or site conditions. The response path should follow evidence and the agreed warranty terms—not an unsupported diagnosis.
