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.

A Chinese history report (查博士, 精真估, or 4S-shop records) usually contains several sections. Here's how to read them. Accident records: entries tagged 重大事故 (major accident) or listings at an insurance payout above 30% of the car's value are serious red flags. Airbag deployment is a deal-breaker for most buyers. Mileage timeline: check that mileage increases logically between service visits. A sudden drop between two dates means odometer tampering—walk away. Ownership count: more than 3 owners in 5 years suggests a problem car. Also check the 使用性质 field: a car registered as 营运 (commercial/taxi use) has a much shorter legal lifespan. Maintenance entries: consistent 4S dealership records are a good sign; long gaps aren't necessarily fatal if the owner used independent shops, but ask for receipts. Cross-check the report against the VIN plate, registration certificate, and physical inspection. If the report shows no accidents but paint thickness readings say otherwise, trust the metal, not the paper.

Most new car manufacturers' e-SIMs are directly soldered onto the T-Box motherboard (surface-mounted) and cannot be removed and replaced like a phone. Unauthorized desoldering of the motherboard may cause complete communication failure in the vehicle, and we strictly prohibit this operation.
