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.

Testing is mandatory. Troubleshooting electrical devices in the car is part of the standard procedure. We will test the window lift motors, mirror folding, air conditioning compressor and fan, electric seat tracks, etc. Any stuttering or failure of electronic components will be recorded.

Our documentation department has the latest versions of UN38.3 (United Nations Transport of Dangerous Goods Test and Standards) and MSDS reports authorized or filed by major Chinese new energy brands (such as BYD, Geely, GAC), which are essential customs documents for declaring dangerous goods to the maritime authority.
