The first preset position may be the position at the center of the power exchange platform 7 , the first preset angle may also be the angle shown in FIG. 5 , and the first preset position may be the position along the first direction X.

Exemplarily, as shown in FIGS. 6 and 7 , the power exchange device 5 rotates at an angle of 90° to the second preset angle as the power exchange platform 7 rotates. The power exchange platform 7 in Figure 6 reaches the second preset angle after rotating 90° clockwise, and the power exchange platform 7 in Figure 7 reaches the second preset angle after rotating 90° counterclockwise. FIG. 8 shows a schematic diagram of the power swapping device 5 on the power swapping platform 7 in a second preset position. The second preset position may be the initial position where the power swapping device 5 just enters the power swapping platform 7 .

While adjusting the placement angle of the power exchange equipment 5, the vertical height of the power exchange equipment 5 is raised, which shortens the time for the power exchange equipment 5 to move toward the power device 6, effectively improving the power exchange efficiency.

Optionally, the above-mentioned steps S31 and S32 can also be performed simultaneously with step S2. During the process of using the power exchange platform 7 to move the power exchange equipment 5 from the power device 6 to the first preset position, the power exchange equipment can be adjusted at the same time. 5, and at the same time increase the vertical height of the electrical device 6. The above process will simultaneously adjust the movement of the power exchange equipment 5 in three dimensions, including horizontal displacement, vertical displacement and rotation angle adjustment, further improving the movement of the power exchange equipment 5 to the electrical device. 6 efficiency.

S51. The rotation of the power exchange platform 7 drives the power exchange equipment 5 to rotate from the second preset angle to the first preset angle;

S52. At the same time, the power exchange device 5 moves from the first preset position to the second preset position along the first direction X;

S53. At the same time, the floating platform of the power exchange platform 7 drives the power exchange equipment 5 down.

The above-mentioned steps S51, S52 and S53 are performed simultaneously, that is, in the process of using the power exchange platform 7 to move the power exchange equipment 5 from the power device 6 to the second preset position, the placement angle and position of the power exchange equipment 5 are adjusted at the same time. , and at the same time reduce the vertical height of the electrical device 6 .
