SOH (State of Health) measures the battery's remaining capacity as a percentage of its original capacity. Two EVs with the same mileage can have very different SOH depending on charging habits and climate exposure, and since the battery represents 30-50% of a used EV's value, the SOH number is effectively the real price tag. A proper certificate includes current SOH percentage, cell voltage balance, charge cycle counts, battery management system fault codes, and often a projected range estimate. In hot-climate markets like the Gulf, a degraded battery degrades even faster, so a documented SOH above 85-90% is strongly recommended. Exporters who provide verified SOH certificates close deals faster and command better prices, so treat the certificate as a core purchase document, not an extra.

Most models adjust through the central control screen menu, while a few models (like some BYD or MG) retain physical levers or paddles on the center console or steering wheel. We will check if the drag feel when the system engages is linearly normal.

A professional pre-purchase inspection in China normally covers five parts: exterior and interior condition, a lift inspection of the chassis and frame, engine bay checks, a road test, and OBD diagnostics. Prioritize the chassis rails and A/B/C pillars for cut-and-weld repairs, engine oil leaks and timing noises, transmission shift quality, and OBD fault codes — cleared codes leave telltale history data. For EVs, add battery pack casing, insulation values, and battery state of health (SOH). Insist on original timestamped photos with the VIN visible and a written conclusion such as 'fit for export' or 'major defects found.' A report that only says 'good condition' is not worth paying for.
