A comprehensive EV battery inspection should include a State of Health (SOH) analysis, a diagnostic scan for fault codes, a physical inspection of the battery pack, and a complete charging system test.
For international buyers importing an electric vehicle from China, the battery isn't just a component—it's the most valuable and critical part of your investment. Unlike a traditional engine, its condition isn't obvious from a simple test drive. A thorough, documented inspection before shipment is essential to avoid costly surprises upon arrival. Here’s what a proper pre-export EV battery check must cover.
1. State of Health (SOH) Report
The State of Health is the single most important metric, showing the battery's current maximum capacity compared to its original capacity when new. Expressed as a percentage, a higher SOH means more range and a longer lifespan. For a nearly new or quality used EV, you should expect an SOH well above 90%. This report provides a clear, data-backed assessment of the battery’s value and remaining life.
2. Diagnostic Trouble Code (DTC) Scan
Every modern EV has a sophisticated Battery Management System (BMS) that monitors individual cells, temperatures, and charging behavior. A professional diagnostic tool can scan the BMS for any stored Diagnostic Trouble Codes (DTCs). A clean scan is a great sign, while codes related to cell imbalances, overheating events, or communication errors can be major red flags indicating hidden issues that need to be addressed before export.
3. Physical Casing and Component Inspection
The battery pack is housed in a protective casing underneath the vehicle. This casing must be inspected for any signs of impact, cracks, corrosion, or fluid leaks (coolant). Damaged seals or casings can compromise the battery's safety and weather resistance. At Starvia Automotive, our available 200-Point SGS/BV Inspection includes a detailed check of the battery's physical condition to ensure it is structurally sound and safe for shipment.
4. Charging System Functionality Test
Finally, the vehicle's entire charging system must be verified. The inspection should confirm that the EV charges correctly using both standard AC charging and DC fast charging. The test ensures the charging port is functional, the vehicle communicates properly with the charging station, and it can complete a full charging cycle without generating errors. This confirms the entire high-voltage system is operating as designed.
