The driving mechanism 303 is connected to the platform body 302, and the driving mechanism 303 is also connected to the drive control device 304 in a communication manner. For example, the drive mechanism 303 may be communicatively coupled to the drive control apparatus 304 by a wired or wireless means. The driving control device 304 may control the driving mechanism 303 to drive the platform body 302 to move up and down along the guide rail 3010 between the power exchanging platform 20 and the floating platform 10. The driving control device 304 may be disposed on the battery replacement platform 20.

In some embodiments, since the lower docking portion 104 of the floating platform 10 is elevated with the water level, the lower docking position of the platform body 302 is adjusted with the water level, so that the platform body 302 can dock with the lower docking portion 104. Lift platform 30 further includes a first position sensing member 305 fixedly coupled to floating platform 10. The first position sensing element 305 is communicatively coupled to the drive control device 304, for example, the first position sensing element 305 may be communicatively coupled to the drive control device 304 via a wired connection.

For example, a fully charged battery on the power exchanging platform 20 is transported to the lifting platform 30, the lifting platform 30 lowers the fully charged battery to the floating platform 10, the driving control device 304 may control the driving mechanism 303 to drive the platform body 302 to move downward along the guide rail 3010, when the platform body 302 moves downward to a first position, the first position sensing element 305 outputs an approaching position state of the platform body 302 relative to the floating platform 10, the driving control device 304 controls the driving mechanism 303 to decelerate the platform body 302, the first position may be an installation position of the first position sensing element 305 or a position at the same altitude as the first position sensing element 305, and the approaching position state of the platform body 302 relative to the floating platform 10 may be a position state where a distance between the bottom of the platform body 302 and the low docking portion 104 is a first preset distance. When the platform body 302 continues to move downwards to the second position, the first position sensing element 305 outputs the docking position state of the platform body 302 relative to the floating platform 10, and the driving control device 304 controls the driving mechanism 303 to stop moving the platform body 302, so that the platform body 302 is accurately docked with the low docking portion 104. The second position may refer to a position where the bottom of the platform body 302 is flush with the lower docking portion 104, and the docking position state of the platform body 302 with respect to the floating platform 10 may refer to a position state where the bottom of the platform body 302 is aligned with the lower docking portion 104.
