Direct answer
Ask for model-specific evidence showing where temperature is sensed, the trigger logic, the response, recovery behavior and fault indication. A claim such as “temperature protected” is incomplete without the exact revision and test conditions. Review drawings, instructions and controlled test records, then confirm the production sample matches the evidenced design.
Who should use this guide?
This guide is for a private-label ev brand making a supplier evidence review 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 |
|---|---|---|
| Identity | Model, hardware/firmware revision and label | Tie every record to the sample |
| Sensing | Sensor location and monitored point | Confirm what is and is not protected |
| Response | Threshold basis, derating or shutdown behavior | Review controlled test trace |
| Recovery | Automatic/manual reset and hysteresis | Check instructions and repeat test |
| Production control | BOM/change record and final check | Define revalidation triggers |
How should the buyer verify it?
- Freeze the claimed model and revision.
- Request a functional description and sensor-location evidence.
- Review a controlled temperature-versus-current/time test record.
- Confirm fault indication and safe recovery behavior.
- Match the sample label, BOM revision and instructions to the evidence.
- Add sensor, control or material changes to the revalidation agreement.
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?
- Accepting a generic report for a different adapter.
- Assuming a housing sensor proves contact temperature is controlled.
- Publishing a threshold that the supplier has not documented.
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
FAQ
Does an IP rating prove temperature protection?
No. Ingress protection and temperature-control behavior are different claims.
Can buyers set one universal trigger temperature?
No. The safe value and method are model-specific and must come from the approved design and applicable requirements.
