During concrete implementation, the preset distance range can be reasonably set according to the length of the battery transferring conveying line. Corresponding sensors are arranged on the battery transferring and conveying line, and the sensors sense the sensing parts on the batteries, so that the distance between the batteries and the exchange positions is within a preset distance range. When the distance between the battery and the potential changing position or the distance between the battery and the potential changing position is within a preset distance range, the battery transferring and conveying line is controlled to operate in a speed reduction mode, and therefore stability and accuracy of battery conveying are guaranteed. The sensor may be at least one of an infrared sensor, a touch sensor, a proximity sensor, and a vision sensor.
