Wherein, battery transfer apparatus 4 can be further connected with foundation 6 through fixed knot constructs (e.g. screw thread fixed knot constructs etc.) to prevent battery transfer apparatus 4 to produce the removal with respect to foundation 6, improve the stability of trading the power plant.

As shown in fig. 2, since the battery transferring device 4 is used for transferring the battery pack 7 between the charging rack 3 and the battery changing device 2, the battery transferring device mounting area 63 is disposed on the side of the charging rack mounting area 62 facing the moving channel 61 in this embodiment, that is, the battery transferring device 4 can be mounted on the side of the charging rack 3 facing the battery changing device 2, so that the battery transferring device 4 is located between the charging rack 3 and the battery changing device 2, which is convenient for the battery transferring operation of the battery transferring device 4, and improves the battery changing efficiency.

The battery pack 7 can be stored in the space of the charging frame 3 above the foundation 6, and the battery transferring device 4 can take the battery pack 7 above the foundation 6 and then move to the battery transferring device mounting area 63 to transfer the battery pack 7 with the battery changing device 2.

Further, as shown in fig. 5, the lengths of the moving path 61, the charging rack mounting area 62, and the battery transferring apparatus mounting area 63 in the vehicle traveling direction are the same, so that the processing of the foundation 6 is more convenient. In other alternative embodiments, the lengths of the moving path 61, the charging rack mounting area 62, and the battery transfer apparatus mounting area 63 in the vehicle traveling direction may also be different from each other, or two of them may also be the same and one different.

As shown in fig. 2 and 4, the vehicle platform 5 is mounted in a vehicle platform mounting area 64, and the vehicle platform mounting area 64 provides a mounting space for the vehicle platform 5, so that the vehicle platform 5 can be conveniently mounted and fixed. Specifically, the upper surface of the foundation 6 is recessed downward to form a vehicle-carrying platform mounting region 64, the vehicle-carrying platform mounting region 64 is located directly above the moving channel 61, the lower end of the vehicle-carrying platform mounting region 64 directly penetrates through to the moving channel 61, and the length of the vehicle-carrying platform mounting region 64 in the vehicle traveling direction (Y direction in fig. 3) is longer than the length of the moving channel 61 in the vehicle traveling direction, so that the vehicle-carrying platform 5 can be mounted at the upper end opening of the foundation 6 without sinking into the moving channel 61. One end of the rail 611 in the moving channel 61 extends to a region close to the battery transferring device mounting region 63, and the other end extends to a position right below the vehicle platform mounting region 64, so as to realize the power exchanging operation of the power exchanging device 2.

In this embodiment, the moving channel 61, the charging frame installation area 62, the battery transferring device installation area 63 and the vehicle loading platform installation area 64 are designed into a concave structure, so that on one hand, the quick positioning of the battery changing device 2, the charging frame 3, the battery transferring device and the vehicle loading platform 5 on the foundation 6 is facilitated, the installation efficiency is improved, and the positioning structure is not required to be independently arranged on the foundation 6, so that the cost is reduced. On the other hand, the sunken structure can also play a limiting role on the battery replacement equipment 2, the charging frame 3, the battery transfer equipment and the vehicle carrying platform 5, so that the possibility that the battery replacement equipment 2, the charging frame 3, the battery transfer equipment and the vehicle carrying platform 5 move relative to the foundation 6 is reduced, and the stability of the battery replacement station is improved. In addition, since the power exchanging device 2 is disposed in the recessed moving channel 61, the power exchanging operation can be directly performed under the electric vehicle 1 without lifting the electric vehicle 1, so that the power exchanging step is simplified, and the potential safety hazard is reduced.

In order to prevent the battery changing apparatus 2 from interfering with the vehicle platform 5 when the electric vehicle 1 is changed under the vehicle platform 5, the depth of the vehicle platform mounting area 64 needs to be smaller than the depth of the moving path 61.
