[0059] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0060] Example 1

[0061] like Figure 1 and Figure 2 As shown, this embodiment discloses a battery swap station for replacing the battery pack of an electric vehicle. The battery swap station includes a battery swap room 1, a battery swap platform 2, and a battery swap device 3. The battery swap room 1 is used to store the battery pack and realize the charging and discharging of the battery pack. The battery swap platform 2 is used to dock the electric vehicle. The battery swap device 3 is used to transfer the battery pack between the battery swap room 1 and the battery swap platform 2.

[0062] Specifically, Figure 1-Figure 3 As shown, the battery exchange room 1 includes a battery exchange box 13, a control cabinet 14, a charging cabinet 15, a charging rack 16, a battery transfer device 17, a counterweight block 18, and a hydraulic station 19.

[0063] like Figure 1 and Figure 2 As shown, this embodiment adopts the structure of a container to form a battery exchange box 13, and the control cabinet 14, charging cabinet 15, charging rack 16, counterweight 18, and hydraulic station 19 are all arranged in the battery exchange box 13; the charging cabinet 15 is connected to the charging rack 16, and the charging rack 16 is used to store the battery pack and charge and discharge the battery pack through the charging cabinet 15; the battery transfer device 17 is used to transfer the battery pack between the charging rack 16 and the battery exchange equipment 3; the counterweight 18 is connected to the battery transfer device 17 to reduce the driving force of the battery transfer device 17 to drive the battery pack to move up and down, improve the service life of the driving motor of the battery transfer device 17, and ensure the stability of the operation of the battery transfer device 17; the hydraulic station 19 is used to provide power for the battery transfer device 17 and other structures. The control cabinet 14 is used to control the electrical and communication in the battery exchange room 1 to ensure the reliability of the battery exchange operation.

[0064] In other alternative embodiments, the battery exchange box 13 may also be formed by splicing plates of other structures.

[0065] like Figure 1 As shown, the battery exchange box 13 in this embodiment is an integral structure and is placed vertically. Compared with the traditional horizontal placement of the container-type battery exchange room, the vertically placed battery exchange box 13 occupies a relatively smaller area, saving land resources and reducing the cost of station construction. Among them, the vertical placement of the battery exchange box 13 specifically means that after the battery exchange box 13 is placed, the length and width of the battery exchange box 13 in the horizontal direction are smaller than the height of the battery exchange box 13 in the vehicle height direction, thereby reducing the footprint of the battery exchange box 13.

[0066] In other alternative embodiments, the battery exchange room 1 also includes a plurality of battery exchange boxes 13, which are stacked in sequence along the height direction of the vehicle, so that the volume of the battery exchange room 1 can be adjusted according to actual needs to accommodate different numbers of battery packs. In addition, the height of a single battery exchange box 13 can be reduced, thereby reducing the manufacturing cost of the battery exchange box 13.

[0067] Example 2

[0068] Based on Example 1, this embodiment further discloses an assembly method of a power exchange room 1, which is used to assemble the power exchange room 1 in Example 1. The power exchange box body 13 in this embodiment is an integral structure.

[0069] like Figure 4 and Figure 5 As shown, the assembly method of the power exchange chamber 1 includes the following steps:

[0070] Before installing other structures inside the battery swap box 13, the battery swap box 13 is placed horizontally to reduce the need for high-altitude operations, reduce the assembly difficulty for workers, and improve the safety of workers.

[0071] In other alternative embodiments, the assembly method of the battery exchange room 1 may not include the step of placing the battery exchange box 13 horizontally, and the battery exchange box 13 is directly placed vertically, that is, the charging rack 16, the charging cabinet 15, the battery transfer device 17, the counterweight 18 and other structures are directly installed inside the battery exchange box 13 when the battery exchange box 13 is placed vertically.

[0072] The charging rack 16 is installed inside the battery swap box 13. Specifically, the charging rack 16 is installed inside the battery swap box 13 when the battery swap box 13 is placed horizontally, which makes installation more convenient, reduces the need for high-altitude operations, reduces the difficulty of assembly for workers, and improves the safety of workers. The charging rack 16 can be first independently assembled and then connected and fixed to the battery swap box 13 as a whole, or the charging rack 16 can be formed by directly erecting columns and beams inside the battery swap box 13. After the charging rack 16 is installed in the battery swap box 13, the battery swap box 13 is vertically aligned.

[0073] In other alternative embodiments, the charging rack 16 can also be installed by hoisting it into the battery exchange box 13 through a hoisting device (such as a crane, etc.) after the battery exchange box 13 is vertically aligned.

[0074] A charging cabinet 15 is installed inside the battery exchange box 13. Specifically, the charging cabinet 15 is installed inside the battery exchange box 13 when the battery exchange box 13 is placed horizontally, which makes installation more convenient, reduces the need for high-altitude operations, reduces the difficulty of assembly for workers, and improves the safety of workers. The charging cabinet 15 can be first independently assembled and then connected and fixed to the battery exchange box 13 as a whole, or the charging cabinet 15 can be formed by directly erecting columns and beams inside the battery exchange box 13. After the charging cabinet 15 is installed in the battery exchange box 13, the battery exchange box 13 is vertically aligned.

[0075] like Figure 5 As shown, since the charging cabinet 15 is installed on the upper side of the charging rack 16, even if the battery exchange box 13 is in a horizontal position, it is necessary to transport the charging cabinet 15 to the inside of the battery exchange room 1 for installation through a lifting device (such as a crane, etc.). The lifting transportation method is simple and convenient to operate.

[0076] In other alternative embodiments, the charging cabinet 15 can also be installed by hoisting it into the battery exchange box 13 through a hoisting device (such as a crane, etc.) after the battery exchange box 13 is vertically aligned.

[0077] In other alternative embodiments, if the charging cabinet 15 is installed on the lower side of the charging rack 16, the charging cabinet 15 can be directly transported to the interior of the battery exchange box 13 without lifting.

[0078] The battery transport device 17 is installed inside the battery exchange box 13. Specifically, the battery transport device 17 is installed inside the battery exchange box 13 after other structures are installed in the battery exchange box 13 and it is vertically aligned, thereby facilitating the installation and commissioning of the battery transport device 17. Among them, "installing other structures in the battery exchange box 13" here refers to the structural parts that need to be installed when the battery exchange box 13 is placed horizontally (such as the charging rack 16, the charging cabinet 15, etc.).

[0079] A counterweight 18 is installed inside the battery exchange box 13. Specifically, the counterweight 18 is installed after the battery transfer device 17 is installed in the battery exchange box 13, that is, the counterweight 18 is also installed when the battery exchange box 13 is in a vertical position.

[0080] The control cabinet 14 is pre-integrated inside the battery exchange box 13. Specifically, the control cabinet 14 is installed inside the battery exchange box 13 when the battery exchange box 13 is placed horizontally, which makes installation more convenient, reduces the need for high-altitude operations, reduces the difficulty of assembly for workers, and improves the safety of workers. The control cabinet 14 in this embodiment is directly built inside the battery exchange box 13. After the control cabinet 14 is installed in the battery exchange box 13, the battery exchange box 13 is vertically aligned.

[0081] In other alternative embodiments, the control cabinet 14 may be first independently assembled and then integrally connected and fixed to the battery exchange box 13 .

[0082] The control cabinet 14 in this embodiment is installed on the upper side of the charging rack 16 and is located between the two charging cabinets 15. Therefore, even if the battery exchange box 13 is in a horizontal position, it is necessary to use a lifting device (such as a crane, etc.) to transport the control cabinet 14 to the inside of the battery exchange room 1 for installation. The lifting transportation method is simple and convenient to operate.

[0083] In other alternative embodiments, the control cabinet 14 can also be installed by hoisting it into the inside of the battery exchange box 13 through a hoisting device (such as a crane, etc.) after the battery exchange box 13 is vertically aligned.

[0084] In other alternative embodiments, if the control cabinet 14 is installed on the lower side of the charging rack 16, the control cabinet 14 can be directly transported to the interior of the battery exchange box 13 without lifting.

[0085] It should be noted that the installation order of the charging rack 16, the charging cabinet 15, and the control cabinet 14 in the battery exchange box 13 is not fixed, but it is more preferred to install the charging rack 16 first, and then install the charging cabinet 15 and the control cabinet 14. In addition, the installation of the charging rack 16, the charging cabinet 15, and the control cabinet 14 in this embodiment refers to the installation of the external frame structure of the charging rack 16, the charging cabinet 15, and the control cabinet 14, so as to facilitate the later installation of working equipment such as chargers and electrical components. The assembly method of the battery exchange room 1 in this embodiment does not include the installation of working equipment such as chargers and electrical components.

[0086] A hydraulic station 19 is installed inside the battery exchange box 13. Specifically, the hydraulic station 19 can be installed when the battery exchange box 13 is placed vertically. The hydraulic station 19 is installed below the control cabinet 14, making full use of the space in the height direction of the battery exchange room 1, making the internal structure of the battery exchange room 1 more compact, improving the utilization rate of the internal space of the battery exchange room 1, reducing the floor space of the battery exchange room 1, and thus reducing the floor space of the battery exchange station and reducing the cost of station construction.

[0087] Furthermore, the hydraulic station 19 in this embodiment can be transported to the interior of the battery exchange room 1 by a forklift or other structure, and the transportation method is simple and convenient to operate.

[0088] In this embodiment, the battery exchange box 13 can be vertically adjusted by a lifting device (such as a crane, etc.), and the adjustment method is simple and convenient to operate.

[0089] Example 3

[0090] This embodiment is basically the same as Embodiment 2, except that the battery exchange room 1 in this embodiment includes a plurality of battery exchange boxes 13 stacked in sequence along the height direction of the vehicle.

[0091] The assembly method of the power exchange chamber 1 also includes the following steps:

[0092] By splicing a plurality of battery exchange boxes 13, the volume of the battery exchange room 1 can be adjusted according to actual needs to accommodate different numbers of battery packs.

[0093] Specifically, multiple battery exchange boxes 13 are laid horizontally on a horizontal plane, and multiple battery exchange boxes 13 are horizontally spliced ​​on the horizontal plane. After the multiple battery exchange boxes 13 are spliced, the whole formed by the multiple battery exchange boxes 13 is vertically aligned. The horizontal splicing method eliminates the need for workers to splice the battery exchange boxes 13 at a height, improves safety, reduces the alignment accuracy requirements between the battery exchange boxes 13, and improves splicing efficiency.

[0094] In this embodiment, the charging rack 16 is installed in the battery exchange box 13 before the multiple battery exchange boxes 13 are horizontally spliced ​​together, which facilitates the installation of the charging rack 16 in the battery exchange box 13.

[0095] After multiple battery exchange boxes 13 are horizontally spliced, the charging racks 16 in different battery exchange boxes 13 are spliced. The charging racks 16 in different battery exchange boxes 13 are connected to each other to ensure the stability of the battery transfer device 17 during operation.

[0096] Multiple battery exchange boxes 13 are spliced ​​before installing the battery transport device 17 to facilitate the installation and debugging of the battery transport device 17.
