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.

Chinese standard electric vehicles use the national standard (GB/T) charging interface. If your country uses the European standard (CCS2), American standard (CCS1), or Japanese standard (CHAdeMO), the vehicle cannot be plugged directly into local charging stations. To address this issue, we will recommend or provide high-quality certified adapters (Adapter) with CE/UL safety certification. Please confirm the charging station specifications in your area with our sales personnel before purchasing.

Obtaining precise internal resistance at different SOC levels requires disassembling the battery pack and connecting it to a professional charge-discharge cabinet for several days of cycling tests. This is beyond the scope of non-destructive used car inspections; we only provide real-time estimated internal resistance data based on OBD port readings.
