It's extremely difficult. Unauthorized modifications can lead to module current overload protection, resulting in a lock. In China, you need to use the factory online engineer account to reprogram it. It's basically impossible to perform online decoding overseas. We strongly warn against blindly modifying the electrical systems of modern integrated circuit vehicles.

We understand that the power battery is the core asset of an EV. Before export, our technical team will use professional OBD diagnostic equipment to read the underlying data from the Battery Management System (BMS). We will provide you with a technical report that includes key indicators such as battery health percentage (SOH), cell pressure differences, and charge-discharge cycle counts. If the SOH is below our established export safety standard (usually above 80%, depending on the vehicle's age), the vehicle will be intercepted and not sent overseas.

Start by checking the after-sales clause in your contract—reputable exporters typically offer 3-12 months of parts support. The usual process: send the exporter a fault description with photos or a short video, plus your VIN and contract number. They will confirm whether it is a warranty case or a paid parts order. For warranty claims, common resolutions are free parts shipped with your next container, or a credit/refund for parts you source locally. Keep all communication in writing. To avoid long waits, ask for the OE part numbers in advance and check whether local dealers stock the same components—many Chinese brands share suppliers. Ordering common wear parts (filters, brake pads) together with the car shipment is the cheapest option by far.
