All our measuring instruments (especially calipers, paint thickness gauges, and refrigerant pressure gauges) are calibrated quarterly according to ISO quality management system requirements to ensure the data we provide you is objective, accurate, and reliable.

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.

Our technical report will read the environmental information from the vehicle's factory-issued documentation (including certifications like National V, National VI, etc.). You need to submit the specific emission limit data we provide (such as grams of CO, THC, NOx emissions) to your country's environmental or customs authorities for compliance comparison.
