For example, when the distance between the battery and the battery replacement position is within a preset distance range, the battery transferring and conveying line is controlled to operate at a reduced speed, so that the accuracy of battery conveying is improved. When the distance between the battery and the exchange position is within the preset distance range, the battery transfer conveying line is controlled to operate in a speed reduction mode, and therefore the accuracy of battery conveying is improved.

In the battery conveying process, 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 reducing mode, and the stability of battery conveying can be improved.

As an optional implementation manner, during the battery transportation process, the stopping mechanism is controlled to be started to position the battery based on the battery replacement instruction and the in-position transmission information generated by the first detection element or the second detection element.

For example, when the battery is conveyed to the battery replacement position, the first detection part detects the trigger part, the in-place transmission information is generated, the stopping mechanism is started according to the in-place transmission information to stop the battery, the battery is limited to move continuously, and the battery is positioned. When the battery is conveyed to the exchange position, the second detection piece detects the trigger piece, in-place transmission information is generated, the stopping mechanism is started according to the in-place transmission information to stop the battery, the battery is limited to move continuously, and the battery is positioned.

At least one of the front side and the rear side along the battery conveying direction is provided with a blocking mechanism, the transmission of the battery is further ensured to be in place through the blocking mechanism, the blocking mechanism is controlled to be started to position the battery based on the battery replacement instruction and the transmission in-place information generated by the first detection piece or the second detection piece, the blocking mechanism can be timely and effectively started to position the battery, and the accuracy of battery transmission is improved.

Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
