Direct answer
Give every shared adapter a unique asset ID and model/revision record. At each return, log the user, vehicle/charger combination, session result and an external inspection of housing, cable or interface, latch, labels, caps and contamination. Quarantine on damage, abnormal heat or odor, moisture ingress, repeated errors, missing identity, or an overdue model-specific inspection.
Who should use this guide?
This guide is for a fleet and rental operator making a asset-control procedure decision. Keep every conclusion tied to a named model, revision, equipment pair, market and check date.
What should be checked before a decision?
| Check | What to record | Decision |
|---|---|---|
| Check-out | Asset ID, user, intended equipment and condition | Prevent unapproved combinations |
| Check-in | Date, session result and external inspection | Catch new damage promptly |
| Quarantine | Reason, photos and case owner | Prevent accidental reissue |
| Retirement | Supplier limit, failed evaluation or uneconomic repair | Record disposition and replacement |
How should the buyer verify it?
- Create an asset register with model, revision and purchase batch.
- Use a short before/after external inspection checklist.
- Require error codes and equipment IDs for failed sessions.
- Apply a visible quarantine tag and separate storage location.
- Retire through the supplier-approved or local e-waste process.
What evidence should the supplier provide?
Request the model and revision, direction diagram, AC/DC role, ratings and instructions, supported-equipment statement with a check date, relevant market documents, change history and a sample-validation record. Evidence for a similar SKU is not evidence for this one.
What mistakes create avoidable risk?
- Sharing adapters without traceable IDs.
- Erasing failure history after one successful session.
- Using a calendar retirement interval not supported by the model instructions or condition record.
Compatibility and safety boundary
Compatibility is a relationship among the charger, cable or adapter, vehicle, software or network and target market. Stop use for damage, abnormal heat or odor, moisture at an interface, loose locking or repeated errors. Do not open or repair high-voltage charging equipment.
Buyer checklist
- Full equipment path and connector direction recorded
- AC or DC role and target market confirmed
- Exact model and revision tied to evidence
- Vehicle, charger and software/network scope dated
- Representative validation retained
- Exceptions and escalation owner documented
