The specific battery swapping method is briefly as follows:

[0088] a. When two pure electric vehicles enter the battery swap station at the same time and are parked in the first parking station and the second parking station in turn, the specific steps include the following steps:

[0089] S1: The third transfer module 11 is located at the first battery handover station, the fourth transfer module 12 is located at the second battery handover station, and the external device places full batteries on the third transfer module 11 and the fourth transfer module 12 respectively.

The design, production and assembly time required by the battery disassembly and transfer device is greatly shortened. By introducing the buffer station and using two transfer modules for transferring batteries, the low battery can be removed and transferred to the buffer station while the full battery is ready at the unlocking and locking station during the battery swap process of the pure electric vehicle, so that the battery swap time of the battery disassembly and transfer device is greatly shortened, and the battery swap efficiency of the pure electric vehicle is improved. By setting the rotatable rotating plate, the angle of the rotating plate can be adjusted to select different battery support points for different sizes of batteries, so that the battery can run smoothly on the transfer module. By setting the angle sensor, the control unit of the battery disassembly and transfer device can accurately master the angle of the rotating plate, so that the rotating plate can be accurately rotated to the required angle. By setting the limiting strip and the limiting block, the situation that the transfer module deviates from the track due to failure during movement is avoided, and the reliability of the battery disassembly and transfer device is improved. By setting the displacement sensor, the control unit of the battery disassembly and transfer device can accurately master the movement position of the transfer module, which helps to realize accurate battery swap. By setting the battery in-place sensor, the control unit of the battery disassembly and transfer device can accurately master whether the battery is on the transfer module, which also helps to realize accurate battery swap.

[0096] It should be emphasized that: the above is only the preferred embodiment of the application, not any form of limitation on the application, any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the application still belongs to the scope of the technical solution of the application.

When the second transfer module (3) moves to the unlocking station, the unlocking platform rises and lifts the battery on the second transfer module (3) until the battery leaves the second transfer module (3), after which the second transfer module (3) moves to the buffer station; at the same time, the first transfer module (2) moves to the unlocking station.

2. The battery disassembly and transfer device according to claim 1, characterized in that: It also includes a drive mechanism (5) for driving the transfer module (1) to move on the track (4), and a connecting rod (6) for connecting the first transfer bracket (1a) and the second transfer bracket (1b).

3. The battery disassembly and transfer device according to claim 1, characterized in that: It also includes a rotating plate (7) that is rotatably connected to the first transfer bracket (1a) and is used to support the battery.

4. The battery disassembly and transfer device according to claim 3, characterized in that: The first transfer bracket (1a) is provided with an angle sensor for detecting the rotation position of the rotating plate (7).

5. The battery disassembly and transfer device according to claim 1, characterized in that: The transfer module (1) is provided with a limiting strip (9a), and the track (4) is provided with a limiting block (9b) for blocking the limiting strip (9a).

6. The battery disassembly and transfer device according to claim 1, characterized in that: It is also equipped with a displacement sensor for detecting the movement distance of the transfer module (1).

7. The battery disassembly and transfer device according to claim 1, characterized in that: The transfer module (1) is equipped with a battery in-situ sensor.

8. A battery swapping station, characterized in that: The device includes a ground floor (10a) and an underground floor (10b) located below the ground floor (10a). The underground floor (10b) is equipped with a battery disassembly and transfer device as described in any of claims 1-7. A vehicle parking area is provided in the area of ​​the ground floor (10a) corresponding to the unlocking / unlocking station. A battery storage rack is provided in the area of ​​the ground floor (10a) corresponding to the battery handover station. The external device is a palletizer for exchanging batteries between the battery handover station and the battery storage rack. The palletizer is located on the side of the battery handover station away from the unlocking / unlocking station.

9. A battery swapping method, characterized in that: Using any one of the battery disassembly and transfer devices according to claims 1-7, the battery disassembly and transfer device is located under the battery swapping vehicle, the transfer module (1) includes a first transfer module (2) that can freely move between the unlocking / unlocking station and the battery handover station, and a second transfer module (3) that can freely move between the unlocking / unlocking station and the buffer station, including the following steps: S1: The unlocking platform rises and removes the low-power battery from the bottom of the vehicle; at the same time, the first transfer module (2) is located at the battery handover station, the second transfer module (3) moves to the unlocking station, and the external device places the fully charged battery into the first transfer module (2). S2: The unlocking platform descends, and the low-power battery follows and descends synchronously until the low-power battery lands on the second transfer module (3), and continues to descend until the unlocking platform separates from the low-power battery; S3: The second transfer module (3) carries the low-power battery to the buffer station; at the same time, the first transfer module (2) carries the fully charged battery to the unlocking station; S4: The unlocking platform rises, allowing the fully charged battery to leave the first transfer module (2), and after the fully charged battery is installed on the vehicle, the unlocking platform descends until the low-charge battery on the second transfer module (3) can pass above the unlocking platform; S5: The first transfer module (2) moves to the battery handover station, and the second transfer module (3) carries the low-power battery to the unlocking station; S6: The unlocking platform rises to lift the low-power battery until it leaves the second transfer module (3). S7: The second transfer module (3) moves to the buffer station; at the same time, the first transfer module (2) moves to the unlocking station; S8: The unlocking platform descends, and the low-power battery follows and descends synchronously until the low-power battery lands on the first transfer module (2), and continues to descend until the unlocking platform separates from the low-power battery; S9: The first transfer module (2) carries the low-power battery to the battery handover station; S10: The external device receives a low-power battery.
