In the power exchanging process, the lifting driving member 61 drives the transmission shaft 711 to rotate, and the first platform 21 is driven to ascend through the rotation of the cam 717 under the action of the first transmission mechanism 71.

Alternatively, when the alignment mechanism on the second platform 22 moves to the first alignment position, the positioning mechanism on the first platform 21 can follow up to the corresponding position. For example, when the first platform 21 moves horizontally to the battery replacement position of the electric vehicle 13, the second platform 22 is far away from the battery replacement position of the electric vehicle 13 compared with the first platform 21; when the second platform 22 moves horizontally to the battery replacement position of the electric vehicle 13, the first platform 21 is far away from the battery replacement position of the electric vehicle 13 compared with the second platform 22.
