At the remote server side, there may be manual support, or it may be provided by an automated running program that may search for similar situations from the electric vehicle history maintenance database and feed back the corresponding solution based on, for example, existing information. For example, the external data processing device can also be configured to perform the entire diagnostic process in accordance with instructions from the remote data server side. In this case, the operator on site can collect status information and fault codes from the electronic control unit through an external data processing device, and then transmit the relevant information to the remote data server, which can be used by professionals on the server side. The processing device guides the operator on site, for example, instructing the field operator to further provide auxiliary information such as photos and videos to assist in fault diagnosis, or perform some trials to correct the problem. With such a remote diagnostic system, engineers can detect problems and determine the root cause of the fault via the communication network without having to go to the repair store to check the problem. As a result, the user of the electric motor vehicle can even obtain after-sales maintenance service without leaving the house.
