step 210, the push-pull device 10 is controlled to push the battery pack 20 away from the extension mechanism 16.
In this step 210, the battery swapping system will drive the push-pull device 10 to move forward on the extending mechanism 16, so that the protrusion on the push-pull device 10 will abut against the battery pack 20 and push the battery pack 20 to leave the extending mechanism 16, and the battery pack 20 will be separated from the battery swapping device, thereby achieving pushing and placing of the battery pack 20.
After step 210, the method further includes steps 220, 230, and 240, namely, after controlling the push-pull device 10 to push the battery pack 20 away from the extension mechanism 16, the method further includes the following steps:

After step 210, the battery swapping system will control the first driving motor 102 to turn on, thereby disengaging the engaging mechanism 101 from the battery-side engaging portion 201. Then, the battery replacement system controls the first driving motor 102 to be turned off and the second driving motor 14 to be turned on, so that the push-pull device 10 moves backwards and retracts, and the push-pull device 10 retracts into the clamping mechanism 101.

In step 225, the detection device detects whether the engagement mechanism 101 is in the disengaged state; when the clamping mechanism 101 is not in the disengaged state, the detection device sends an un-disengaged signal to the battery replacement system and is used for controlling the first driving motor 102 to be turned on until the clamping mechanism 101 is disengaged from the battery side clamping part 201; when the engaging mechanism 101 is in a disengaged state, the detecting device sends a disengagement signal to the battery replacement system and is used to control the first driving motor 102 to be turned off and the second driving motor 14 to be turned on, so as to control the push-pull device 10 to retract into the engaging mechanism 101. By detecting whether the clamping mechanism 101 is in the disengagement state, the phenomenon that the battery pack 20 falls off due to the fact that the clamping mechanism 101 moves backwards in the non-disengagement state is effectively avoided, and the safety and stability of the battery replacement system in the process of taking and placing the battery pack 20 are greatly improved.
