In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, "multiple" refers to at least two.

[0080] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0081] First refer to Figure 1 , the extended battery compartment of this application is introduced.

[0082] like Figure 1As shown, in order to solve the problem that existing battery swap stations cannot flexibly match changes in order volume, the extended battery compartment 10 of the present application includes a shell 11, a first battery rack 12 and a first docking piece 13. One side of the shell 11 is open, and the first battery rack 12 is arranged in the shell 11. The first battery rack 12 forms a plurality of bins for storing power batteries 30. Each bin is equipped with a charging connector, which can be connected to the power battery 30 in the bin to charge the power battery 30 and exchange data with the battery management system on the power battery 30. The first docking piece 13 is arranged on the shell 11 and is directly or indirectly connected to a plurality of charging connectors. The first docking piece 13 is arranged to be able to dock with a second docking piece arranged on the box of the battery swap station (to be described in detail below) to achieve the transmission of power and / or signals.

[0083] In this way, when the battery swap station needs to improve its service capacity, the extended battery compartment 10 can be transported to the battery swap station and quickly spliced ​​with the battery swap station, thereby increasing the available number of power batteries 30. After splicing, the first docking piece 13 docks with the second docking piece of the battery swap station to achieve power and signal transmission, so that the battery swap station can timely obtain the status of the power battery 30 in the extended battery compartment 10, and selectively allocate the power battery 30 in the station according to the status of the power battery 30.

[0084] The technical solution of the present application provides an extended battery compartment 10, which can be used as a separate module, so that the battery swap station can flexibly match the changes in order volume. Specifically, only a small battery swap station needs to be built to reduce the difficulty and cost of site selection. During non-holidays, the small battery swap station can meet the battery swap demand, and during holidays, the extended battery compartment 10 can be spliced ​​to one side of the battery swap station to quickly increase the number of batteries in the battery swap station and improve the service capacity of the battery swap station.

[0085] Refer to the following Figures 1 to 6 , and introduces a specific implementation method of the present application in combination with a battery swap station group.

[0086] First refer to Figure 1 In a possible implementation, the extended battery compartment 10 includes a shell 11, a first battery rack 12, a first docking member 13, a first guide member 14, a bidirectional power module 15, a charging device 16 and a distribution box 17.

[0087] The shell 11 is a rectangular structure assembled from a frame and sheet metal parts, one side of which is open, and the other side walls are closed by sheet metal parts. There are multiple first battery racks 12. In the figure, there are two first battery racks 12, and the two first battery racks 12 are arranged side by side inside the shell 11. Each battery rack is provided with multiple slots, each of which can store a power battery 30. Each slot is also provided with a charging connector, which can be connected to the power battery 30 through the charging connector to realize the transmission of power and signals. Among them, the charging connector is also a water and electricity connector, and its water connector and electric connector can be integrally arranged on a mounting base, or of course, they can be arranged separately. No matter how it is arranged, it is a conventional technical means in this field and will not be repeated in this application.

[0088] Those skilled in the art can understand that the specific formation method of the housing 11 is not unique. In addition to being assembled from a frame and sheet metal parts, it can also be other structures, such as being welded from sheet metal parts. In addition, the specific structure and number of the first battery rack 12 are not limited in this application, and those skilled in the art can make a selection based on specific application scenarios.

[0089] See also Figure 1 and Figure 5 The first docking member 13 can be a male end or a female end of a connector. Taking the male end as an example, a cable interface, a signal pin and a power pin are arranged on it. The cable interface is connected to the charging connector through a cable, and the signal pin and the power pin can be connected to the signal socket and the power socket of the female end of the connector to realize the transmission of power and signal. Figure 1 In the illustrated embodiment, two first docking members 13 are provided, the two first docking members 13 are provided on the bottom frame of the open side of the housing 11 , and the two first docking members 13 are respectively connected to part of the charging connectors.

[0090] Of course, the specific setting method of the first docking member 13 is not unique, and those skilled in the art can adjust it as long as the first docking member 13 can achieve docking with the second docking member 24 and effectively transmit power and / or signals. For example, the first docking member 13 can be provided with only a signal pin or a power pin, and the transmission of power and signals can be achieved by setting a plurality of first docking members 13 of different categories. For another example, the first docking member 13 can also use the female end of the connector. For another example, only one first docking member 13 can be provided, or more can be provided, and the number is not limited in this application. For another example, the first docking member 13 is provided on the bottom frame of the open side of the shell 11 to facilitate its connection with the box body of the battery swap station. Of course, those skilled in the art can adjust the setting position of the first docking member 13 as long as it can achieve effective connection with the second docking member. For example, the first docking member 13 can be fixed or movable, and the first docking member 13 can be manually connected to the second docking member to achieve docking between the two.

[0091] Continue to see Figure 1 and Figure 5 The first guide member 14 is a guide plate. Figure 1 In the embodiment shown, two guide plates are provided, and the two guide plates are fixedly connected to the bottom frame of the open side of the housing 11, and each guide plate is provided adjacent to a first docking member 13. A V-shaped notch is provided on the guide plate, and the first guide member 14 can be matched and docked with the second guide member provided on the box body of the battery swap station through the notch. In this way, by providing the first guide member 14, the difficulty of the docking process between the extended battery compartment 10 and the battery swap station can be reduced.

[0092] Those skilled in the art can understand that although the present application is described in conjunction with the first guide member 14 as an example, the first guide member 14 is not required, and those skilled in the art can choose whether to set the first guide member 14 based on the specific application scenario. When setting the first guide member 14, the setting position and setting quantity of the first guide member 14 can also be adjusted, as long as the guidance of the docking process can be achieved. For another example, the specific structure of the first guide member 14 can be adjusted, for example, it can also be set to a guiding structure such as a tapered groove, or it can be swapped with the second guide member 25 below.

[0093] See also Figure 1 and Figure 6 The distribution box 17 is arranged on an outer wall of the housing 11, and a plurality of bidirectional power modules 15 are arranged inside the distribution box 17. The first docking member 13 is connected to the plurality of bidirectional power modules 15, and each bidirectional power module 15 is connected to one or more charging connectors. The bidirectional power module 15 is relatively common in the art and will not be described in detail in this application.

[0094] The charging device 16 in the present application is a charging gun, which is connected to the bidirectional power module 15 and plugged into the distribution box 17 . Figure 1 In the illustrated embodiment, two charging guns are provided, and the two charging guns are respectively plugged into two sides of the distribution box 17 .

[0095] By providing a bidirectional power module 15, bidirectional transmission of power can be achieved. Not only can the power battery 30 be charged through the bidirectional power module 15, but the battery in the extended battery compartment 10 can also be discharged outward, thereby improving the utilization rate of the power battery 30. By providing a charging device 16, the bidirectional power module 15 can be used to release the power in the power battery 30 to the charging device 16, so that the charging device 16 can be used to charge the vehicle, further improving the service capability.

[0096] Those skilled in the art can understand that the setting of the distribution box 17 is not necessary. Those skilled in the art can choose whether to set the distribution box 17 based on the specific application scenario. When the distribution box 17 is not set, the related bidirectional power module 15 and other components can be set in the extended battery compartment 10 and other locations. In the case of setting the distribution box 17, the distribution box 17 can be set inside the shell 11 in addition to the outer wall of the shell 11, and those skilled in the art can freely choose. The setting of the bidirectional power module 15 is not necessary. Those skilled in the art can choose based on the specific application scenario. When the bidirectional power module 15 is not set, a unidirectional power module can be set to charge the power battery 30, or the power battery 30 can be charged by the power module in the charging box of the battery swap station. At this time, the charging device 16 can also be omitted. In addition to the charging gun, the charging device 16 can also be set as a charging pile. The charging pile and the shell 11 are set independently of each other. The charging pile can be independently installed near the shell 11 and connected to the bidirectional power module 15 through a cable. The number of charging devices 16 is also not restrictive, and those skilled in the art can adjust it. For example, only one charging device 16 can be set, or three or more can be set.

[0097] Refer to the following Figures 2 to 5 , the battery swap station of this application is introduced.

[0100] The second docking piece 24 is used in pairs with the first docking piece 13. For example, the second docking piece 24 can be selected from the female end or the male end of the connector. Taking the female end as an example, a cable interface, a signal socket and a power socket are provided thereon. The cable interface is connected to the charging cabinet and the electric control cabinet at the same time. The signal socket and the power socket can be connected to the signal pin and the power pin of the male end of the connector to realize the transmission of power and signals. In the present application, the number of the second docking pieces 24 is set to two corresponding to the number of the first docking pieces 13. The two second docking pieces 24 are arranged on the bottom frame of the first side of the box body 21, and each second docking piece 24 can be connected to one first docking piece 13.

[0101] The second guide member 25 is a guide block, and corresponding to the guide plate, two guide blocks are provided, and the two guide blocks are fixedly connected to the first side bottom frame provided on the box body 21, and each guide block is provided adjacent to a second docking member 24. The guide block is formed with a guide sharp angle matching the V-shaped notch, and the second guide member 25 can be matched and docked with the first guide member 14 provided on the shell 11 of the extended battery compartment 10 through the guide sharp angle.

[0102] By providing a door body 211 on the box body 21, it is convenient to achieve the connection between the box body 21 and the extended battery compartment 10. By providing a second docking member 24, power and / or signal transmission between the extended battery compartment 10 can be achieved. The second battery rack is provided between the stacker 23 and the battery exchange platform 22, so that after the extended battery compartment 10 is docked with the box body 21, the stacker 23 can directly dock with the battery in the extended battery compartment 10, so that the extended battery compartment can be connected and used immediately. By providing a second guide member 25, it is convenient to reduce the difficulty of docking the extended battery compartment 10 with the box body 21.

[0103] Of course, the above-mentioned configuration is merely exemplary, and those skilled in the art may adjust it based on specific application scenarios so that the present application can be applicable to more specific application scenarios.

For another example, the second docking member 24 is provided on the first side bottom frame of the box body 21 to facilitate its connection with the shell 11 of the extended battery compartment 10. Of course, those skilled in the art can adjust the setting position of the second docking member 24, as long as it can achieve effective connection with the first docking member 13. For example, the second docking member 24 can be fixedly provided or movably provided, and the first docking member 13 and the second docking member 24 are manually connected to achieve docking between the two.

[0107] For another example, the second guide member 25 is not required, and those skilled in the art can choose whether to set the second guide member 25 based on the specific application scenario. When setting the second guide member 25, the setting position and setting quantity of the second guide member 25 can also be adjusted, as long as the guidance of the docking process can be achieved. For another example, the specific structure of the second guide member 25 can be adjusted, for example, it can also be set to a structure that can achieve guidance, such as a tapered column, or it can be set in a swapped position with the first guide member 14 mentioned above.

[0108] The present application also provides a battery swap station group, including the battery swap station 20 and the extended battery compartment 10 in the above embodiment, the open side of the shell 11 of the extended battery compartment 10 faces the first side of the box body 21 of the battery swap station 20, and the first docking member 13 and the second docking member 24 are docked with each other.

[0109] The battery swap station group of the present application, through the combination of the battery swap station 20 and the extended battery compartment 10, can reduce the difficulty and cost of site selection, improve the service capacity of the battery swap station 20 during peak periods, and enable the battery swap station 20 to flexibly match changes in order volume.

[0110] A possible application process of the extended battery compartment of the present application is introduced below.

[0111] During non-holidays, the order volume is relatively small, and the battery swapping demand can be met by the battery swapping station 20. When the order volume is relatively large during holidays, the extended battery compartment 10 is transported and placed on one side of the battery swapping station 20, and the extended battery compartment 10 is spliced ​​together with the battery swapping station 20 under the guidance of the first guide member 14 and the second guide member 25. After splicing, the first docking member 13 and the second docking member 24 dock with each other. At this time, the extended battery compartment 10 can not only increase the number of batteries for the battery swapping station 20 and improve the service capacity of the battery swapping station 20, but also release the power of the fully charged battery to the charging pile through the discharge function of the bidirectional power module 15 to charge passing vehicles.

[0112] If the battery swap station 20 has power capacity, the power battery 30 in the extended battery compartment 10 can be directly charged. If the battery swap station 20 does not have power capacity, the power battery 30 in the extended battery compartment 10 can also be fully charged at a fixed location and then transported to the side of the battery swap station 20 for service.
