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.

We will use a megohmmeter (insulation resistance tester) to measure the insulation resistance of the high-voltage bus. If the resistance value is below the national safety standard, it indicates a risk of leakage, and the vehicle will be deemed unqualified.

The original Chinese license plates are obscured to protect the previous owner's personal privacy, and also because the plates have been forcibly reclaimed by Chinese traffic management after the vehicle completed the "transfer pending export" registration. This serves as physical proof that the vehicle has legally and compliantly completed the upgrade.
