We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).

Currently, in most developing countries, there is a severe lack of deep repair capabilities for the three electric systems. We recommend that B2B car dealers must have basic electrical insulation testing capabilities.

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.
