As some embodiments of the present application, the batteries of the battery storage device 100 are transferred by the first battery replacement trolley and the second battery replacement trolley. In addition, the first layer and the second layer of the battery storage device 100 each have a bearing mechanism 20. The first battery replacement trolley can lift the full battery upwards from below along the height direction (i.e., the Z direction shown in the figure) of the storage rack 10, so as to transfer the full battery to the preset position of the second layer of the battery storage device 100.

The first battery replacement trolley can lift the full battery upwards from below along the height direction (i.e. the Z direction shown) of the storage rack 10, so as to transport the full battery to the preset position of the second last layer of the battery storage device 100. Then, the driving member 21 of the second last layer can drive the bearing member 23 to move at least part of the bearing member 23 towards the inside of the frame 11 through the transmission assembly 22, so as to bear the full battery. Then, the second battery replacement trolley can lift the depleted battery upwards from below along the height direction (i.e. the Z direction shown) of the storage rack 10, so as to transport the depleted battery to the preset position of the last layer of the battery storage device 100. The driving member 21 of the last layer can drive the bearing member 23 to move at least part of the bearing member 23 towards the inside of the frame 11 through the transmission assembly 22, so as to bear the depleted battery.

Then, the driving member 21 of the second last layer can drive the bearing member 23 to move at least part of the bearing member 23 towards the inside of the frame 11 through the transmission assembly 22, so as to bear the full battery. Then, the second battery replacement trolley can lift the depleted battery upwards from below along the height direction (i.e. the Z direction shown) of the storage rack 10, so as to transport the depleted battery to the preset position of the last layer of the battery storage device 100. The driving member 21 of the last layer can drive the bearing member 23 to move at least part of the bearing member 23 towards the inside of the frame 11 through the transmission assembly 22, so as to bear the depleted battery. Through the above process, the depleted battery and the full battery can be stored in the storage rack 10.

[0085] Then, the first battery replacement trolley receives the depleted battery upwards, and the driving member 21 of the last layer can drive the bearing member 23 to move at least part of the bearing member 23 towards the outside of the frame 11 through the transmission assembly 22, so that the first battery replacement trolley can transport the depleted battery transported by the second battery replacement trolley away, for example, to the charging device to charge the depleted battery.

[0086] ​Subsequently, the second battery replacing trolley upwardly receives the full battery, since the drive member 21 of the last layer drives the carrier 23 to move, so that at least part of the carrier 23 moves towards the outside of the frame 11, therefore the second battery replacing trolley will not interfere with the bearing mechanism 20 arranged on the last layer, the drive member 21 of the second last layer can drive the carrier 23 to move through the transmission assembly 22, so that at least part of the carrier 23 moves towards the outside of the frame 11, thereby enabling the second battery replacing trolley to transfer the full battery transferred by the first battery replacing trolley, thereby enabling the vehicle to replace the full battery.

[0087] In this way, the frame 11 is provided with a plurality of bearing mechanisms 20, which can reduce the risk of battery overturning and improve the use reliability of the battery storage device 100.
