[0003] The current battery swapping field is still a relatively new field, and there is no systematic device that can perform self-inspection on the battery swapping process of the battery swapping station. For the operating battery swapping stations, after each day's business, the staff of the battery swapping station can only perform appearance or functional inspections on the control system of the battery swapping station and the facilities in the battery swapping station, but cannot inspect the dynamic battery swapping process, because the dynamic battery swapping process requires the battery swapping vehicle to enter the battery swapping channel before the battery swapping process of the battery swapping station can be triggered. If the dynamic battery swapping process is not self-checked and the business is started directly, it will also cause business accidents due to abnormal battery swapping process that lead to the inability to swap batteries, seriously affecting the operation of the battery swapping station.

[0046] In step three, after the battery swap station searches and connects to the corresponding Bluetooth or WIFI module based on the vehicle's unique identifier, the vehicle information simulation module of the self-test system establishes a Bluetooth or WIFI communication channel with the battery swap station control system. The vehicle information simulation module of the self-test system sends information to the battery swap station control system through the established Bluetooth or WIFI communication channel at a fixed frequency.
