Validate an EV charging adapter sample against a written use case before approving stock. Record the exact model revision, charger-side connector, vehicle-side inlet, AC or DC mode, and representative charger/vehicle combination. Check fit, locking, start/stop behavior, fault handling, labeling and instructions. Treat every untested combination as unconfirmed.
1. Freeze the intended use before requesting samples
Write the charging path as charger → adapter → vehicle, target market and charging mode. Request the exact-revision datasheet and drawing, then match the sample label to both.
2. Choose representative test equipment
Prioritize charger and vehicle combinations that reflect the planned listing. Record software state and any permissions that can affect charging. One result does not prove universal compatibility.
3. Use a repeatable acceptance record
| Check | Evidence | Decision |
|---|---|---|
| Insertion and release | Photos and notes | No force or interference |
| Latch or lock | Video and cycle notes | Consistent engagement |
| Start and stop | Charger/vehicle record | Expected sequence |
| Fault behavior | Error and conditions | Escalation defined |
4. Separate product approval from listing approval
Review title, compatibility wording, warnings, included accessories and support script only after the sample is accepted. Do not publish unverified ratings or certifications.
5. Control changes after approval
Recheck changes to geometry, electronics, firmware, labels or instructions. Southwind can coordinate samples and OEM/ODM discussion; availability and terms require SKU-level confirmation.
FAQ
How many vehicle models should an online seller test?
Base the selection on listing scope and market, document tested combinations, and keep others unconfirmed.
Is physical connector fit enough?
No. Fit does not verify communication, permissions, limits or fault behavior.
What should trigger retesting?
A relevant model revision or change to product, instructions, environment or claimed compatibility.
