Battery condition is the single most important — and most expensive — variable in a used EV. Ask for a State of Health (SOH) report: in China, dealers and authorized service centers can read it via the manufacturer diagnostic system. It shows remaining capacity as a percentage of the original. Rule of thumb: above 90% is excellent, 85-90% is acceptable for the price, below 80% needs a serious price cut or battery refurbishment. Also get the battery's full charge and discharge history (次数) — a 3-year-old car with 800 fast-charge cycles has lived a harder life than one with 200. Physically, inspect the battery pack enclosure on a lift for dents, corrosion, or coolant leaks. Check that DC fast charging works during a test charge. Finally, verify the battery is not covered by an open recall or replacement program — this is both a risk and sometimes a free upgrade.

A proper pre-shipment inspection is more than photos — it is a documented technical examination covering four areas. 1. Structure: paint thickness readings across the body, weld inspection of pillars and chassis rails, rust assessment underneath. 2. Mechanical: engine compression or at least a cold-start video, transmission shifts through all gears, suspension noise test on uneven roads, brake pad and disc thickness measurements. 3. Electronics: full OBD diagnostic scan with printed fault codes, all lights, windows, AC, infotainment, and driver-assistance functions tested. 4. Documentation: VIN and engine number physically matched to the registration certificate, photos of the certificate itself. Insist on a written report with photos, measured values, and a clear pass/fail conclusion per section. Make final payment conditional on this report, not on the seller's word or showroom-condition photos.

Under CIF terms, the beneficiary of the insurance policy will be endorsed to the buyer. Once the claim is successful, the insurance company's foreign currency compensation will be directly deposited into the buyer's designated overseas company or personal account.
