Set the decision boundary
Cold weather changes energy use and charging behaviour, so model the real route and test the selected vehicle instead of applying one percentage loss.
Write down the destination country and port, intended registration class, steering-side requirement, charging environment, passenger and route needs, accepted drivetrain or range version, condition, budget and delivery point. A changed candidate or destination can invalidate earlier conclusions.
Record ambient and battery temperature, state of charge, preconditioning status, route speed, cabin-heat setting and charge-curve conditions. Cold-weather results without those conditions cannot be compared safely.
Build a winter operating case
Use the destination’s ordinary and severe temperatures, parking exposure, route speed, cabin heat and charger access. Verify preconditioning and charging behaviour on the selected car; do not promise a fixed winter range.
Official context: Review Fangchengbao’s current Tai 3 product information, then match it to the selected vehicle’s build date and labels.
Operating context: The U.S. Department of Energy’s cold-weather EV guidance explains preconditioning, covered parking and cold charging considerations; apply them only after verifying the candidate’s available functions.
Continue the evidence path: First identify the battery and drivetrain in the Tai 3 versions and range guide, then confirm the actual inlet through the charging compatibility route. Include winter assumptions in the landed-cost plan.
Connect every claim to one vehicle
Charging compatibility is physical and regional. Record the installed AC/DC inlet, labels, battery identity, onboard limits, protocol, cable and destination network; then demonstrate charging on the selected vehicle.
Preserve original-language records alongside translations. Dated photographs, diagnostic reports, charging results, inspection findings, quotation and contract should identify the same VIN. If records conflict, stop approval and resolve the difference at source.
Public specifications help frame questions but do not allocate stock or certify an individual car. Official Fangchengbao pages also warn that published configuration may differ from vehicles sold. Production date, physical labels and the sales record remain decisive.
Minimum evidence register
| Checkpoint | Acceptable record | Why it matters |
|---|---|---|
| VIN and original vehicle identity | Original record and clear VIN-linked media | Establishes the exact product being valued |
| production date and exact version | Dated test with method, result and limits | Establishes the exact product being valued |
| battery and motor labels | Named party, cost or approval in writing | Establishes the exact product being valued |
| installed charging inlet and test | Original record and clear VIN-linked media | Controls condition and destination-use risk |
| structural and underbody condition | Dated test with method, result and limits | Controls condition and destination-use risk |
| diagnostics and warning history | Named party, cost or approval in writing | Controls condition and destination-use risk |
| tyres, brakes and suspension | Original record and clear VIN-linked media | Controls condition and destination-use risk |
| seller, contract and beneficiary | Dated test with method, result and limits | Controls payment, export and arrival risk |
| destination approval and landed boundary | Named party, cost or approval in writing | Controls payment, export and arrival risk |
Use a red/amber/green status with an owner and expiry date. Green means supported by current evidence, not guaranteed forever. Amber items need a priced consequence or condition before payment; red items stop the transaction.
Claims that commonly fail
Watch for copied trim names, another market’s brochure, range figures from a different test cycle, an inlet inferred from the badge, diagnostic screenshots without VIN, edited walk-around videos, excluded export work, and connected features assumed to operate overseas.
Do not convert missing evidence into a positive claim. Record what is unknown, who must prove it and what happens if it remains unresolved. Price uncertainty separately from confirmed defects so a buyer can compare candidates consistently.
Destination boundary
China-side inspection and export work cannot guarantee destination tax, conformity, registration, public charging, app access, warranty, insurance or future software service. Obtain local advice before a deposit and refresh it whenever vehicle, route or rules change.
Carry the decision to handover
Keep the accepted VIN, specification, condition and included work on the quotation, contract, invoice, export documents and loading record. Before carrier handover, record odometer, state of charge, keys, cables, accessories, faults and all exterior panels.
Verify the contract entity and beneficiary independently. Any changed bank instruction, vehicle, exporter, freight route, delivery term or price reopens approval. Preserve the final evidence pack after delivery for registration, service and dispute handling.

Request a Tai 3Buyer questions
Is there one reliable winter-range reduction for every Tai 3?
No. Temperature, battery temperature, speed, cabin heat, tyres, wind, gradient, load and parking exposure change consumption. Build ordinary and severe route cases and retain an arrival reserve.
How should a Tai 3 cold-weather charging test be recorded?
Record ambient and battery temperature, starting state of charge, preconditioning, charger type and power, charging curve, cabin use and session duration on the selected VIN.
Should a Tai 3 always be charged to 100 percent in winter?
No single target suits every trip. Follow the vehicle guidance and battery limits, then choose a starting charge and reserve for the actual route, temperature and available fallback chargers.
