We understand that the power battery is the core asset of an EV. Before export, our technical team will use professional OBD diagnostic equipment to read the underlying data from the Battery Management System (BMS). We will provide you with a technical report that includes key indicators such as battery health percentage (SOH), cell pressure differences, and charge-discharge cycle counts. If the SOH is below our established export safety standard (usually above 80%, depending on the vehicle's age), the vehicle will be intercepted and not sent overseas.

Start by asking the seller for a photo of the full vehicle registration certificate. Check that the registered owner matches the seller's company name. Any change of ownership should appear with a transfer stamp and date. Second, request a lien check. In China, vehicle mortgages are registered with the vehicle management office. A clean certificate shows no mortgage registration; if one exists, the car cannot be legally exported until the loan is settled and the lien released. Third, verify there are no unpaid traffic fines and no gaps in compulsory insurance, since these can block export clearance. Ask the platform to include a title verification step in the transaction flow, and only pay the balance after the title transfer to the export company is confirmed.

Once the car system (especially in a closed ecosystem) undergoes a major version upgrade, its bootloader is usually locked, preventing downgrades. If this happens, there is basically no solution in an overseas environment. Therefore, we strongly warn: do not blindly insert a USB drive to upgrade while offline.
