Define the buyer’s real question
Record a complete conditioned session on the identified iDD version; a connector photo or peak-power claim cannot prove charging fit or battery health.
Record destination, intended registration, steering side, daily and long-distance route, passengers, luggage, charging access, accepted powertrain, new or used condition, budget and delivery point. A changed candidate or destination reopens affected checks.
Apply the model-specific test
Charging availability and limits can differ by production version, and the observed session depends on charger capability, starting state of charge, temperature, recent driving and software. Record both sides of the connection and distinguish AC equipment, any applicable DC capability and destination infrastructure. Never apply another PHEV specification merely because a plug looks similar.
Inspect physical hardware through the iDD inlet, lock and water route.
Run the complete evidence sequence
Identify candidate and hardware
Record VIN, production date, exact iDD version, battery identity, inlet, labels, supplied equipment and relevant software. Do not assign a later production update to an earlier car without VIN-specific proof.
Describe the charger
Record connector, protocol, rated power, load sharing, voltage or current limits, session identifier and network status. A high station rating does not establish accepted vehicle power.
Capture starting conditions
Note ambient and available battery temperatures, state of charge, recent route, preconditioning, warnings and auxiliary loads. Similar cars tested under different conditions are not directly comparable.
Log the useful session
Record state of charge, voltage, current, power, time, interruption and cooling behavior at intervals. One peak screenshot cannot reveal taper, heat limitation or unstable communication.
Interpret abnormalities carefully
Separate normal taper, charger limitation, temperature effect and repeatable vehicle fault. Isolation, high-voltage or thermal warnings require qualified diagnosis and controlled retest.
Apply the destination boundary
Check local connector and protocol, home supply, reliable stations, account access, climate, route reserve and gasoline fallback. An adapter does not automatically solve signalling or network compatibility.
Official context: Review the current Changan UNI-Z product page and match it to the selected vehicle.
Evidence specific to this decision
Charging availability and limits can differ by production version, and the observed session depends on charger capability, starting state of charge, temperature, recent driving and software. Record both sides of the connection and distinguish AC equipment, any applicable DC capability and destination infrastructure. Never apply another PHEV specification merely because a plug looks similar.
Keep one VIN across the file
Energy planning changes completely between gasoline and iDD. A PHEV buyer must prove battery identity and charging compatibility; a gasoline buyer must verify engine, DCT, emissions and fuel/service support.
Preserve original-language records beside translations. Connect photos, diagnostic output, charging or road tests, inspection, quotation and contract to the same VIN. Conflicts stop approval until resolved at source.
| Evidence | What to record |
|---|---|
| Identity | VIN, production plate, legal model, powertrain and version |
| Condition | Dated physical checks, history, diagnostics and test results |
| Compatibility | Destination consequence, limitation and responsible reviewer |
| Commercial | Seller, beneficiary, included work, validity and delivery term |
Energy decision file
For iDD, record inlet, charging limits, battery identity, diagnostics, temperature and a controlled session. For gasoline, record fuel, emissions, engine and DCT behaviour.
Charging availability changes PHEV value, while fuel and hybrid-service access vary. Compare the complete ownership environment.
Test an ordinary day and an adverse day
Use realistic passengers, luggage, weather, speed, gradients, traffic and energy availability. For iDD, include a failed charger and battery reserve. For gasoline, include local fuel, emissions and workshop constraints. A specification is context, not a guarantee of suitability.
Mark each conclusion green, amber or red with evidence date and owner. Amber needs a priced consequence or condition; red stops payment. Do not turn missing proof into a positive feature claim.
Preserve the approved vehicle to delivery
Carry VIN, version, condition and included work through quotation, contract, invoice, export records and loading media. Record odometer, fuel or charge state, keys, cables, accessories, faults and exterior condition at handover.
China-side work cannot promise destination tax, conformity, registration, charging access, software services, warranty, insurance or future reliability. Refresh local advice if vehicle, route or rules change.
Request a VIN-linked UNI-Z proposalDocuments that keep this decision usable
Create a candidate summary naming the VIN, production date, legal model, powertrain, version, odometer and seller. Attach original identity records, continuous dated media, inspection findings, diagnostic output, road-test notes and charging results where applicable. Each conclusion should identify its source, test condition, limitation, reviewer and expiry point.
Keep the commercial file separate but connected: dated quotation, included and excluded work, inspection conditions, contract entity, bank beneficiary, export responsibility, carrier acceptance and delivery boundary. The destination file records tax or duty advice, conformity, registration, insurance, energy access and workshop support. A changed input reopens the affected decision while preserving the audit trail.
Before loading, compare the approved summary with the physical vehicle and final documents. Record keys, cables, accessories, odometer, fuel or battery state, warnings and visible condition. This final comparison helps prevent a correct inspection being attached to the wrong car.
Buyer questions
Does the inlet prove fast-charging compatibility?
No. Verify protocol, electrical limits, software and an actual suitable session.
Can low session power prove battery degradation?
No. Charger, temperature, state of charge and vehicle conditions must be separated.
Should maximum charge power be guaranteed?
No. Published capability and observed accepted power are different facts.
