[0049] The storage device 2 comprises at least one transfer station 202 and a plurality of storage stations 203. The transfer station 202 and the storage station 203 are used to place the batteries. The transfer station 202 is arranged opposite to the battery replacement device 1. Optionally, at least one storage station 203 can be reserved as the transfer station 202 because there is no difference in structure between the transfer station 202 and the storage station 203. As shown in the drawings, the plurality of storage stations 203 are arranged in a row. At least one of the plurality of storage stations 203 is arranged as the transfer station 202. Optionally, the storage device 2 and the battery replacement work station 4 are arranged on the two sides of the battery replacement device 1 respectively. Figures 1-3

[0050] The transfer device 3 is used to transfer the batteries between the transfer station 202 and the storage station 203.

[0051] The battery replacement station provided in the embodiment of the present application drives the grabbing mechanism to rotate through the rotating platform 101, so that the grabbing mechanism can face any one of the battery replacement work station 4, the charging device and the transfer station 202. During the battery replacement process, the transfer device 3 transfers the full battery of the storage station 203 to the transfer station 202. The battery replacement device 1 removes the low battery of the vehicle 5 parked in the battery replacement work station 4 and places the full battery of the transfer station 202 on the battery position of the vehicle 5. The battery replacement device 1 places the low battery on the charging device. The charging device is used to charge the low battery. After the charging is completed, the battery replacement device 1 places the battery on the charging device on the transfer station 202. The transfer device 3 transfers the battery of the transfer station 202 to the storage station 203 for storage.

[0052] ​In this way, compared with the prior art in which the battery can only be stored at the periphery of the battery replacing device 1, in the battery replacing station provided in the embodiment of the present application, the charging device at the periphery of the battery replacing device 1 is used to charge the battery, and the storage device 2 is used to store the battery, and the battery can be transferred between the battery replacing station 4, the charging device and the transfer position 202 through the battery replacing device 1, and the battery can be transferred between the transfer position 202 and the storage position 203 through the transfer device 3, so that a large number of batteries can be stored in the storage device 2 of the battery replacing station, and the number of batteries that can be stored in the battery replacing station is increased, and the problem that the number of batteries arranged along the periphery of the battery replacing device 1 is small and it is difficult to meet the demand for battery replacement in a large environment in the prior art is solved. Moreover, the charging device is arranged at the periphery of the battery replacing device to charge the battery, and the storage device is responsible for storing the battery, so that the space utilization of the battery replacing station is improved, and the number of batteries that can be placed in the battery replacing station is increased.

[0053] In some embodiments provided in the present application, the storage device 2 comprises a pair of storage racks 201, the pair of storage racks 201 has a spacing therebetween, and the transfer device 3 is arranged between the pair of storage racks 201. As shown in FIG. 1, the storage rack 201 close to the battery replacing device 1 in the pair of storage racks 201 is provided with the transfer position 202. The transfer device 3 is used to transfer the battery between the transfer position 202 and the storage position 203 of any one of the storage racks 201. By arranging the pair of storage racks 201 and arranging the transfer device 3 between the pair of storage racks 201, the battery replacing station provided in the embodiment of the present application can store the battery by using the pair of storage racks 201, so that the number of batteries that can be stored in the battery replacing station is further increased, and the battery replacing capacity of the battery replacing station is improved. Figure 1

[0054] In some embodiments provided in the present application, the storage rack 201 comprises at least two layers of storage positions 203, and each layer comprises a plurality of storage positions 203 arranged in sequence. In this way, the space in the battery replacing station can be fully utilized to store the battery, so that the battery replacing capacity of the battery replacing station is improved. Alternatively, the storage rack 201 can be a rack structure formed by welding or fastening a profile.

[0055] ​In some embodiments provided by the present application, at least one storage position 203 is provided with a charging device. As described above, the space on the side of the battery swap device 1 is limited, so the charging device is also limited. In the case of a large amount of battery swap, the charging may not be timely, so by providing a charging device in the storage position 203, the low-battery battery can be charged in the storage position of the storage device, thereby improving the charging efficiency of the battery swap station, and further enabling the battery swap station to quickly provide more fully charged batteries, thereby further meeting the working scenario with a large amount of battery swap. It should be noted that the volume of the charging device is usually large, so when the charging device is arranged in the storage position, the number of charging devices should be determined based on the actual battery swap amount to avoid occupying the storage space of the battery.

[0056] In some embodiments provided by the present application, the transfer device 3 is a stacker. In this way, the structure of the transfer device 3 is simple.

[0057] In some embodiments provided by the present application, the stacker comprises a first walking device 301, a lifting device 302, a telescopic device 303, and a first connecting device 304. The first walking device 301 is movably arranged. Optionally, a guide rail is arranged on the ground of the battery swap station, and the extension direction of the guide rail is the same as the length direction of the storage rack 201. The first walking device 301 is slidably arranged on the guide rail, and the first walking device 301 can move along the guide rail under the drive of a walking wheel, a screw nut driving mechanism, a gear and rack driving mechanism, or an oil cylinder. The lifting device 302 is installed on the first walking device 301. The telescopic device 303 is installed on the lifting device 302, and the lifting device 302 is used to drive the telescopic device 303 to lift. For example, the lifting device 302 comprises a support, a sliding seat, and a driving mechanism. The support is connected with the first walking device 301, the sliding seat is slidably arranged on the support in the vertical direction, and the driving mechanism is used to drive the sliding seat to lift. The driving mechanism can be a screw nut driving mechanism, a gear and rack driving mechanism, a hoist wire rope, or an oil cylinder. The telescopic device 303 is installed on the lifting device 302, and the lifting device 302 is used to drive the telescopic device 303 to lift. The telescopic device 303 can be arranged as a telescopic fork, for example, the telescopic device 303 is a multi-stage telescopic fork. The telescopic direction of the telescopic device 303 is towards both sides of the moving track of the first walking device 301. The first connecting device 304 is installed on the telescopic device 303, and the first connecting device 304 is used to connect with the battery. The telescopic device 303 is used to drive the first connecting device 304 to move. For example, the first connecting device 304 is provided with a telescopic latch, and the first connecting device 304 can be placed into the top frame of the battery, and the latch is extended to be able to be clamped with the top frame of the battery.

[0058] The stacker first moves by the cooperation of the first walking device 301 and the lifting device 302 to enable the first connecting device 304 to be aligned with the transfer position 202 or the storage position 203, and then the first connecting device 304 is driven by the telescopic device 303 to extend to the top of the battery, and the first connecting device 304 is placed into the top frame of the battery by the lifting device 302, and the first connecting device 304 is connected to the top frame by the extended bolt. Then the first connecting device 304 is lifted by the lifting device 302 to lift the battery. The telescopic device 303 is reset, so that the battery is taken out from the transfer position 202 or the storage position 203. The placing process of the battery is the same as the above, and will not be repeated here.

[0059] In some embodiments provided by the application, the grabbing mechanism of the battery replacing device 1 is provided in pairs, and the moving tracks of the pair of grabbing mechanisms are arranged in parallel. As shown in the figure, the grabbing directions of the pair of grabbing mechanisms are opposite, and of course the grabbing directions of the pair of grabbing mechanisms can also be the same. The working process of the battery replacing device 1 provided with the pair of grabbing mechanisms includes: before the vehicle 5 arrives at the battery replacing station, the full battery placed in the transfer position 202 by the transfer device 3 can be grabbed by the first grabbing mechanism, after the vehicle 5 enters the battery replacing position 4, the low battery of the vehicle 5 is grabbed by the second grabbing mechanism, and then the full battery is placed on the battery position of the vehicle 5 by the first grabbing mechanism, the battery replacing process is completed, and the vehicle 5 can leave the scene. The second grabbing mechanism places the low battery on the charging device for charging. In this way, the vehicle 5 does not need to wait for the battery replacing device 1 to grab the full battery, nor does it need to wait for the battery replacing device 1 to place the low battery on the charging device, that is, the grabbing of the full battery and the placing of the low battery can be operated when the vehicle 5 is not present, so as to reduce the waiting time of the vehicle 5 and improve the battery replacing speed of the vehicle 5.

[0060] In some embodiments provided by the application, the battery replacing device 1 further includes a second walking device 104, and the second walking device 104 is movably arranged, and the rotating platform 101 is installed on the second walking device 104. For example, the bottom surface of the battery replacing station is provided with a guide rail, the extension direction of the guide rail is the same as the length direction of the battery replacing position 4, the second walking device 104 is slidably arranged on the guide rail, and the second walking device 104 can move along the guide rail under the drive of the walking wheel, the screw nut driving mechanism, the gear and rack driving mechanism or the oil cylinder. In this way, when the parking position of the vehicle 5 is not accurate, the position of the grabbing mechanism can be adjusted to be opposite to the battery position of the vehicle 5 by the second walking device 104, so as to facilitate the battery replacing device 1 to replace the battery of the vehicle 5, and at the same time, the accuracy requirement of the parking position of the vehicle 5 can be reduced, thereby reducing the proficiency requirement of the driver.

[0061] Reference Figures 1-6As shown, the embodiment of the present application also provides a battery replacement method, which is implemented based on the battery replacement station, for example, can be implemented based on the battery replacement station described above. It should be noted that the subject of the execution of the battery replacement method can be the battery replacement station control system. The battery replacement method includes steps S100-S800.

[0062] Step S100, control the transfer device 3 to transfer the full battery on the storage position 203 of the storage device 2 to the transfer position 202. Wherein, the storage device 2 includes at least one transfer position 202 and a plurality of storage positions 203.

[0063] Specifically, the storage device 2 includes a pair of storage racks 201, and the pair of storage racks 201 has a spacing therebetween, and the transfer device 3 is arranged between the pair of storage racks 201. Referring to Figure 1 As shown, the storage rack 201 of the pair of storage racks 201 close to the battery replacement device 1 is provided with the transfer position 202. The transfer device 3 can be a stacker. The moving track of the stacker is arranged between the pair of storage racks 201, and is parallel to the length direction of the storage rack 201. The transfer device 3 can realize the transfer of the battery between the transfer position 202 and any one of the storage positions 203 of the storage rack 201. Since the transfer position 202 and the storage position 203 have no difference in structure, at least one storage position 203 can be reserved as the transfer position 202. The storage position 203 is mainly used for storing the full battery, and is usually stored with the full battery. The transfer position 202 is reserved as a transfer space, which is usually kept vacant, and only when there is a demand for transferring the battery between the battery replacement device 1 and the storage position 203, the transfer position 202 will be placed with the battery by the battery replacement device 1 or the transfer device 3.

[0064] Step S200, control one of the grabbing mechanisms of the battery replacement device 1 to grab the full battery on the transfer position 202. Wherein, the battery replacement device 1 includes a rotating platform 101 and a pair of grabbing mechanisms.

[0065] Specifically, the grabbing mechanism is movably arranged on the rotating platform 101. The moving tracks of the pair of grabbing mechanisms are arranged in parallel, and the grabbing directions of the pair of grabbing mechanisms can be opposite or the same. For example, before the vehicle 5 enters the battery replacement station, the full battery on the transfer position 202 can be grabbed by the first grabbing mechanism of the two grabbing mechanisms. The first grabbing mechanism described herein is only for ease of description and should not be understood as a specific limitation of the grabbing mechanism.

Optionally, the battery swapping station 4 and the storage device 2 are respectively arranged on the two sides of the battery swapping device 1.

[0068] Step S400, control the battery swapping device 1 to place the full-power battery on the battery position of the vehicle 5.

[0069] Specifically, taking the battery swapping device 1 with a pair of grabbing mechanisms in opposite directions as an example, after the second grabbing mechanism takes out the low-power battery of the vehicle 5, the rotating platform 101 is controlled to rotate 180°, so that the first grabbing mechanism is opposite to the vehicle 5, and the first grabbing mechanism is controlled to place the full-power battery on the battery position of the vehicle 5.

[0070] Step S500, control the battery swapping device 1 to place the low-power battery on the charging device. The charging device is arranged in multiple, and the multiple charging devices are arranged along the circumference of the battery swapping device 1.

Optionally, the multiple charging devices are arranged in a ring structure, and the side opposite to the battery swapping station 4 of the ring structure is provided with a gap, so that the battery swapping device 1 can pass through the gap to swap the battery of the vehicle 5. Similarly, the side opposite to the transfer position 202 of the ring structure is also provided with a gap, so that the battery swapping device 1 can take and place the battery to the transfer position 202.

[0072] Step S600, control the charging device to charge the low-power battery.

[0073] Specifically, the low-power battery is charged by the charging device to increase the power of the low-power battery.

[0074] Step S700, control the battery swapping device 1 to place the battery on the charging device which has been fully charged on the transfer position 202.

[0075] Specifically, the grabbing mechanism of the battery swapping device 1 is controlled to take off the battery on the charging device which has been fully charged, and place it on the transfer position 202.

[0076] Step S800, control the transfer device 3 to transfer the battery of the transfer position 202 to the storage position 203.

[0077] Specifically, the transfer device 3 is controlled to take out the battery of the transfer position 202, and store the battery to the storage position 203, so as to be taken out for use during battery swapping.
