A peak charging figure is not a session result. The vehicle, charger, starting state, temperature and software must be recorded together before the observed curve can support a route decision. Run a documented session on the identified version and separate vehicle limits, charger limits, temperature effects and faults. The useful outcome is a documented decision that another person can review, not a confident-sounding conclusion detached from the vehicle.
Use this with: charging compatibility guide, battery health evidence and real-range route plan. These pages close adjacent questions without replacing this check.
Short answer
Run a documented session on the identified version and separate vehicle limits, charger limits, temperature effects and faults. Preserve the session record, supplied cables and unresolved compatibility limits in the handover file.
Using one peak-power screenshot can conceal taper, interruption, overheating, charger sharing or an incompatible destination network. Instead, rank confirmed facts, seller-stated claims and open items separately so price comparison does not hide technical uncertainty.
01Identify battery and charging hardware+
Begin by fixing the evidence boundary. Identify battery and charging hardware. For this charge decision, retain the source, date, VIN or candidate reference and the conditions under which the observation was made. Seller wording should remain distinguishable from independently observed evidence.
Run a documented session on the identified version and separate vehicle limits, charger limits, temperature effects and faults. If the evidence conflicts, pause the comparison and request a clearer record rather than averaging incompatible claims. This matters because preserve the session record, supplied cables and unresolved compatibility limits in the handover file.
02Record charger and starting conditions+
Next, compare the record with the physical vehicle. Record charger and starting conditions. For this charge decision, retain the source, date, VIN or candidate reference and the conditions under which the observation was made. Seller wording should remain distinguishable from independently observed evidence.
Run a documented session on the identified version and separate vehicle limits, charger limits, temperature effects and faults. If the evidence conflicts, pause the comparison and request a clearer record rather than averaging incompatible claims. This matters because preserve the session record, supplied cables and unresolved compatibility limits in the handover file.
03Log the useful charging curve+
Treat uncertainty as a line item, not a reason to guess. Log the useful charging curve. For this charge decision, retain the source, date, VIN or candidate reference and the conditions under which the observation was made. Seller wording should remain distinguishable from independently observed evidence.
Run a documented session on the identified version and separate vehicle limits, charger limits, temperature effects and faults. If the evidence conflicts, pause the comparison and request a clearer record rather than averaging incompatible claims. This matters because preserve the session record, supplied cables and unresolved compatibility limits in the handover file.
04Interpret taper and cooling behavior+
Test the result against the buyer's actual daily use. Interpret taper and cooling behavior. For this charge decision, retain the source, date, VIN or candidate reference and the conditions under which the observation was made. Seller wording should remain distinguishable from independently observed evidence.
Run a documented session on the identified version and separate vehicle limits, charger limits, temperature effects and faults. If the evidence conflicts, pause the comparison and request a clearer record rather than averaging incompatible claims. This matters because preserve the session record, supplied cables and unresolved compatibility limits in the handover file.
05Repeat abnormal results+
Close this check before the commercial file moves forward. Repeat abnormal results. For this charge decision, retain the source, date, VIN or candidate reference and the conditions under which the observation was made. Seller wording should remain distinguishable from independently observed evidence.

This matters because preserve the session record, supplied cables and unresolved compatibility limits in the handover file.
06Apply evidence to the destination route+
Repeat the affected check after any corrective work. Apply evidence to the destination route. For this charge decision, retain the source, date, VIN or candidate reference and the conditions under which the observation was made. Seller wording should remain distinguishable from independently observed evidence.

Identify both sides of the session
Record VIN, production date, battery version, inlet, labels and relevant software. Record charger connector, protocol, rated output, load sharing and session identifier; a high charger rating does not prove what the vehicle can accept.
Capture starting conditions
Note ambient temperature, available battery temperature data, state of charge, recent driving, preconditioning status, warnings and auxiliary loads. These conditions explain why two apparently similar sessions may not be comparable.
Log more than the peak
Record time, state of charge, voltage, current, power, interruptions and cooling behavior at useful intervals. Continue far enough to see taper and post-session warnings without creating an unsafe test.
Diagnose unexpected reduction
Compare state of charge, temperature, charger output, communication errors and repeat sessions before calling a low result battery degradation. Refer isolation, thermal or enclosure warnings to qualified personnel.
Build a realistic destination plan
Check connector and protocol, reliable station spacing, account access, climate, reserve and fallback charging. An adapter may change physical connection without solving communication, voltage or public-network support.
Primary reference points
Official material is a starting reference, not a substitute for candidate verification.
Close the file with visible open items.
Preserve the session record, supplied cables and unresolved compatibility limits in the handover file. Record who will resolve every outstanding item and whether it affects purchase, shipping, arrival or later ownership. A replacement candidate receives a new review even when the colour and advertised trim are identical.

Buyer questions
What should be confirmed first for Test Yuan Up / Atto 2 Fast Charging and Thermal Behavior?+
Run a documented session on the identified version and separate vehicle limits, charger limits, temperature effects and faults. The answer must remain tied to one VIN, market version and destination rather than a generic listing.
Can a seller statement replace inspection evidence?+
No. A seller statement can identify a claim, but condition, charging and installed equipment should be supported by dated records or direct observation where practical.
Does this guide guarantee destination registration?+
No. Preserve the session record, supplied cables and unresolved compatibility limits in the handover file. Current customs, tax, registration and electrical requirements must be confirmed with competent destination advisers.
