The battery pack is 30–50% of an EV's value, so its inspection should be the most detailed part of the pre-shipment check. Require these items: 1. BMS data readout: state of health (SOH), full-charge voltage, cell voltage deviation, cycle count, and fast-charging percentage. SOH above 90% is good; below 80% means a costly pack replacement is approaching. 2. Physical inspection: check the underbody for pack dents, coolant leaks from the battery cooling circuit, and corrosion on high-voltage connectors. 3. Range test: a real drive of at least 30–50 km, comparing energy consumption against the rated figure. A pack with poor cells overheats and depletes fast. 4. Charging test: verify both AC and DC charging work, and record charging speed and any error messages. Get the raw diagnostic data, not just a summary. If the inspector won't share the BMS report, assume the battery is the reason why.

Odometer rollback happens everywhere, so never trust the dashboard number alone. Cross-check at least three sources: 1. Maintenance records: Chinese 4S dealerships keep service logs tied to the VIN. Ask the exporter for screenshots showing recorded mileage at each visit — the numbers should rise consistently. 2. Inspection reports: China requires periodic emissions/safety inspections, and the mileage is logged at each one. The exporter can pull the car's inspection history. 3. Tire and wear clues: Compare the claimed mileage with brake pedal rubber, steering wheel shine, seat bolster wear, and the tire production dates. A car showing 30,000 km with a polished steering wheel and second set of tires is suspicious. Also check the dashboard for uneven digits or scratches around the odometer area in photos. If maintenance and inspection records roughly agree, the reading is usually trustworthy; if the seller refuses to share records, treat the mileage as unknown and negotiate accordingly.

You can watch the car through live streaming or VR, or entrust a local third-party agency to inspect the car for you. Transparency about the car's condition is the foundation of trust.
