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.

Absolutely not. The U.S. DOT and EPA have strict import restrictions on non-compliant vehicles. Any Chinese used car that is not 25 years old and not produced to U.S. standards will face mandatory crushing and destruction upon arrival at U.S. ports. We directly reject such non-compliant orders.

For dealers who purchase the same brand models in bulk over a long term, we can coordinate senior technicians domestically to offer paid, regular Zoom video technical Q&A to resolve the issues you encounter locally.
