How to Evaluate an EV Charging Gun Factory

This checklist is for importer sourcing and quality teams conducting an onsite or remote factory review. Focus on whether the factory can repeat an approved model and show the records behind it.
Begin with one real order path
Pick a representative charging gun or cable assembly and follow it from incoming material to packed product. Ask how model code, revision, connector, cable, termination, label and packaging are linked across records.
Review incoming material control
For connectors, terminals, cable, seals, housings and labels, check lot identification, acceptance criteria, nonconforming material handling and traceability. A connector that looks similar to the approved part needs a controlled identification method.
Follow assembly and termination steps
Review cable preparation, termination, strain relief, housing assembly and marking. Compare the current work instruction with the product being assembled, and ask what happens after an engineering change.
Check testing and final inspection records
| Area | Useful evidence |
|---|---|
| Product identity | Model, revision, order and batch link |
| Incoming inspection | Lot record and acceptance result |
| Assembly | Current instruction and in-process check |
| Testing | Test item, equipment and result |
| Final inspection | Appearance, marking, accessories and packing |
| Change control | Review and buyer approval where required |
Test the change-control conversation
Ask what happens if a cable-jacket supplier proposes a replacement. A useful answer includes technical review, document updates, validation needs and customer notification where the approved product could change.
Close the audit with open actions
List missing evidence, owners and due dates. Certification, capacity, MOQ, lead time and available configurations must be verified for the actual model and order.
Review AC charging cable options or prepare a factory review.
FAQ
Is a factory video enough for evaluation?
It can support an early review. A live walkthrough and sampled records are more useful for product-specific details.
Which record should connect the whole process?
The model and revision identity should connect the quote, drawing, sample, production instructions, inspection and packing records.
