[0025] The present invention will be further described and explained below in conjunction with specific embodiments and accompanying drawings:

[0026] Please refer to Figure 1 、 Figure 2 and Figure 3A modular charging and discharging aging cabinet includes a cabinet body 10 and a power supply module 20.

[0027] The power module 20 includes an AC-DC power module 21, a DC-DC power component 22, a first connecting bar 23 and a second connecting bar 24. The AC-DC power module 21 and the DC-DC power component 22 are arranged relatively inside the cabinet 10, and the positive and negative poles of the AC-DC power module 21 and the positive and negative poles of the DC-DC power component 22 are respectively connected in series through the first connecting bar 23.

[0028] One end of the second connection row 24 is connected to the access port of the AC-DC power module 21, and the other end of the second connection row 24 is connected to the external power supply. The cabinet 10 is provided with a cabinet door 12 corresponding to the first connection row 23 and the second connection row 24, and one side of the cabinet door 12 is rotatably connected to the cabinet 10.

[0029] The power supply module 20 includes an AC-DC power supply module 21 and a DC-DC power supply assembly 22. The positive and negative poles of the AC-DC power supply module 21 and the positive and negative poles of the DC-DC power supply assembly 22 are respectively connected in series through a first connecting row 23. The AC-DC power supply module 21 is connected to an external power supply through a second connecting row 24. When connecting, the first connecting row 23 and the second connecting row 24 can be fixed at the interface between the AC-DC power supply module 21 and the DC-DC power supply assembly 22 by conductive fixings such as screws. The first connecting row 23 and the second connecting row 24 can avoid the use of wires for connection, thereby solving the problem of wire organization and storage.

[0030] When people need to adjust, install, maintain or repair the AC-DC power module 21 and the DC-DC power assembly 22 respectively, they only need to unscrew the screws and other fixings, and the first connecting row 23 and the second connecting row 24 are directly fixed to the surface of the power module 20, and do not need to be stored, realizing true modular installation and use.

[0031] In addition, the cabinet body 10 is provided with a cabinet door 12 corresponding to the first connecting row 23 and the second connecting row 24. One side of the cabinet door 12 is rotatably connected to the cabinet body 10. When people make adjustments, they only need to open the cabinet door 12 to disassemble and adjust the first connecting row 23 and the second connecting row 24, thereby facilitating the electrical connection of each module and also facilitating daily maintenance and installation.

[0032] In the above solution, there are multiple power modules 20, which are arranged from top to bottom and connected in series via the second connecting bar 24. The power modules 20 can be configured in multiple ways according to different aging cabinet specifications, and each group of power modules 20 needs to be connected to an external power supply. Therefore, they can be connected in series from bottom to top via the second connecting bar 24, achieving a more efficient connection.

[0033] A circuit breaker 25 is connected in series to one end of the second connection bar 24 connected to the external power source, and the circuit breaker 25 protects the connected AC-DC power module 21 .

[0034] The DC-DC power supply assembly 22 includes several first DC-DC power supply modules 221 and several second DC-DC power supply modules 222. The first DC-DC power supply modules 221 and the second DC-DC power supply modules 222 are arranged side by side, and the first DC-DC power supply modules 221 and the second DC power supply modules are arranged from top to bottom. The positive and negative poles of the several first DC-DC power supply modules 221 are connected in series through the third connecting row 223, and the positive and negative poles of the several second DC-DC power supply modules 222 are connected in series through the fourth connecting row 224, and the positive and negative poles of the third connecting row 223 and the positive and negative poles of the fourth connecting row 224 are connected in parallel through the first connecting row 23.

[0035] For aging cabinets of different specifications, different numbers of DC-DC power modules need to be connected to the AC-DC power module 21, so that the DC-DC power module is divided into a first DC-DC power module 221 and a second DC-DC power module 22, and the corresponding first DC-DC power module 221 and the second DC-DC power module 22 are connected in series, and then connected in parallel with the AC-DC power module 21, so that the space inside the cabinet 10 is more reasonably utilized.

[0036] Please refer to Figure 3 For example, in Example 1, a 16-channel aging cabinet adopts four groups of power modules 20. Each group of power modules 20 includes two AC-DC power modules 21, two first DC-DC power modules 221 and two second DC-DC power modules 222. The two first DC-DC power modules 221 are connected in series through the third connecting bar 223, and the two second DC-DC power modules 222 are connected in series through the third connecting bar 223. Then, the AC-DC power modules 21 corresponding to the upper and lower rows are connected in parallel through the first connecting bar 23.

[0037] Please refer to Figure 4In Example 2, a 24-channel aging cabinet adopts three groups of power modules 20. Each group of power modules 20 includes an AC-DC power module 21, four first DC-DC power modules 221 and four second DC-DC power modules 222. The four first DC-DC power modules 221 are connected in series through a third connecting row 223, and the four second DC-DC power modules 222 are connected in series through the third connecting row 223. Then, the AC-DC power modules 21 corresponding to the upper and lower rows are connected in parallel through the first connecting row 23.

[0038] Please refer to Figure 5 , Example 3, a 32-channel aging cabinet includes seven AC-DC power modules 21, and the sum of the first DC-DC power modules 221 and the second DC-DC power modules 221 is 32.

[0039] The first, second, third, and fourth connecting bars 23, 24, 223, and 224 are each provided with fixing holes through which fixing members are inserted. The first, second, third, and fourth connecting bars 23, 24, 223, and 224 are all made of copper, ensuring good electrical conductivity.

[0040] A data interface 13 is provided on the side of the cabinet body 10, and the power module 20 is connected to the data interface 13 through a wire. After the power module 20 is installed, the power module 20 can be connected to the data interface 13 accordingly. Therefore, when the aging cabinet is in use, the external data can be directly connected to the data interface 13 on the side of the cabinet. At the same time, it also avoids the exposure of wires on the surface of the aging cabinet, making the overall structure more tidy.

[0041] A modular charging and discharging aging cabinet assembly method includes the following steps:

[0042] S1, slide the AC-DC power module 21 and the DC-DC power assembly 22 into the cabinet;

[0044] S3 , electrically connecting the positive and negative electrodes of the AC-DC power module 21 and the positive and negative electrodes of the DC-DC power assembly 22 through the first connecting bar 23 .

[0045] The DC-DC power supply assembly 22 described in the above steps includes a plurality of first DC-DC power modules 221, a plurality of second DC-DC power modules 222, a third connecting bar 223, and a fourth connecting bar 224. The positive and negative electrodes of the plurality of first DC-DC power modules 221 are first connected in series via the third connecting bar 223, and the positive and negative electrodes of the plurality of second DC-DC power modules 222 are connected in series via the fourth connecting bar 224.

[0046] The present invention provides a modular charging and discharging aging cabinet, wherein the power supply module comprises an AC-DC power supply module and a DC-DC power supply assembly, wherein the positive and negative poles of the AC-DC power supply module and the positive and negative poles of the DC-DC power supply assembly are respectively connected in series through a first connecting row, and the AC-DC power supply module is connected to an external power supply through a second connecting row. When the first connecting row and the second connecting row are connected, they can be fixed at the interface of the AC-DC power supply module and the DC-DC power supply assembly by conductive fixing members such as screws. The first connecting row and the second connecting row can avoid the use of wires for connection, thereby solving the problem of wire arrangement and storage. When we need to adjust, install, maintain and repair the AC-DC power module and DC-DC power assembly respectively, we only need to unscrew the screws and other fixings, and the first connecting row and the second connecting row are directly fixed to the surface of the power module and do not need to be stored, realizing true modular installation and use, and the cabinet body is provided with cabinet doors corresponding to the first connecting row and the second connecting row, one side of the cabinet door is rotatably connected to the cabinet body, when people make adjustments, they only need to open the cabinet door to disassemble and adjust the first connecting row and the second connecting row, thereby facilitating the electrical connection of each module and facilitating daily maintenance and installation.
