When the power change vehicle drives into the vehicle positioning power change bin, the battery quick-change device in the first power change bin 500 and the battery quick-change device in the second power change bin 600 move to corresponding positions of a battery box to be transferred according to information sent by the control system; for example, the battery replacement vehicle comprises a first battery box 402 arranged on the top surface of the longitudinal beam and second battery boxes 403 respectively arranged on two side surfaces of the longitudinal beam;

the first bracket 202 of the battery quick-change device in the first battery compartment 500 drives the first insertion arm 203 to adjust to a position corresponding to the bottom of the first battery box 402; the first inserting arm 203 extends out and is inserted into the bottom of the first battery box 402, and after the first inserting arm 203 reaches a set position, the first bracket 202 drives the first inserting arm 203 to ascend, so that the first battery box 402 is separated from the battery replacing vehicle; the second bracket 302 of the battery quick-change device in the first battery compartment 500 drives the second insertion arm 303 to adjust to a position corresponding to the bottom of the second battery box 403; the second inserting arm 303 extends out and is inserted into the bottom of the second battery box 403, and after the second inserting arm 303 reaches a set position, the second bracket 302 drives the second inserting arm 303 to ascend, so that the second battery box 403 is separated from the battery replacing vehicle; the first inserting arm 203 drives the first battery box 402 to retract into the first frame 201, and the second inserting arm 303 drives the second battery box 403 to retract into the second frame 301; then the battery quick-change device in the first battery compartment 500 carries the detached first battery box 402 and second battery box 403 to move, and the first battery box 402 and second battery box 403 are placed on the empty battery rack through the arm inserting action, and the charging device on the first battery rack 502 performs the charging operation on the battery quick-change device in the replaced first battery compartment 500. The battery quick-change device in the first battery change bin 500 moves to a battery rack position with a fully charged battery box, and the fully charged battery box is moved into the first frame 201 and the second frame 301 through the action of the inserting arm; then moving to the vicinity of the battery replacement vehicle; and mounting the fully charged battery box to the corresponding position of the battery replacement vehicle. Then the battery quick-change device in the first power battery compartment 500 is retracted to the corresponding position of the first power battery compartment.

All the above-mentioned actions of detaching the battery box, placing the battery box and the like of the first battery transfer part and the second battery transfer part can be performed simultaneously, and can also be performed successively according to actual requirements, for example; when the battery box is placed, the first battery transfer part can be placed on one first battery rack 502, and the second battery transfer part can be placed on the other battery rack later; the first battery transfer unit and the second battery transfer unit may also be operated simultaneously to place the first battery box 402 and the second battery box 403 on the first battery rack 502 of one double layer.

The method for replacing and transferring the battery box of the battery quick-change device in the second battery replacing bin refers to the method for replacing and transferring the battery box of the battery quick-change device in the first battery replacing bin; the battery quick-change device in the second battery replacing bin can act simultaneously with the battery quick-change device in the first battery replacing bin, and therefore battery replacing time is saved. The action time interval between the battery quick-change device in the second battery replacing bin and the battery quick-change device in the first battery replacing bin can be adjusted according to actual requirements.

A fourth aspect of the embodiment of the present application provides a battery swapping system, which includes a control system and the battery swapping station;

the control system is electrically connected with the battery quick-change device in the first electricity-changing cabin 500 and the battery quick-change device in the second electricity-changing cabin 600 respectively;

the control system is configured to control the battery quick-change device in the first battery compartment 500 to transfer the first battery box 402 and the second battery box 403 to the first battery placement portion along the first travel track 501;

the control system is further configured to control the battery quick-change device in the second power change bin 600 to transfer the third battery box 404 and/or the fourth battery box to the second battery placement portion along the second travel track 601.

In this embodiment of the application, a first battery replacement monitoring system and a first charging system are further disposed in the first battery replacement bin 500;

a second battery replacement monitoring system 603 and a second charging system 604 are arranged in the second battery compartment.
