[0043] Based on the above, in view of the defects of poor assembly efficiency, unchanged maintenance and expansion caused by the need to first install the mechanical unit into the cabinet during the assembly of conventional battery charging and discharging equipment, and then connect the sampling lines, signal lines, power lines and other wires of each component on the mechanical unit to the electrical cabinet in the cabinet one by one, the inventive concept of this application is to realize internal electrical connection of each component on the mechanical unit 10 on one side of the press 100, so that when the mechanical unit 10 is connected to the cabinet 20, all electrical connections can be made by connecting them with independent connecting lines, thereby improving assembly efficiency and making maintenance and expansion more convenient.

[0044] It should be noted that, in the battery formation and capacity separation in the embodiments of the present application, formation refers to the implementation of low-current charging and discharging, constant temperature static and other process measures on the initially charged battery to stabilize its performance; capacity separation refers to the evaluation of the capacity and performance of the battery through specific testing means after the battery has been formed, so as to screen out batteries with performance that meets the requirements; the battery formation and capacity separation is often achieved through the battery charging and discharging equipment 1000.

[0045] refer to Figures 1 to 3 As shown, Figure 1 A schematic diagram of the overall structure of the mechanical unit provided in an embodiment of the present application; Figure 2 A schematic diagram of a partial structure of a mechanical unit provided in an embodiment of the present application; Figure 3 This is a front view of the maintenance area of ​​the mechanical unit provided in an embodiment of the present application.

[0046] An embodiment of the present application provides a mechanical unit 10, including: a press 100, capable of supporting a battery for lifting and lowering movements; a probe module 200, connected to the press 100, and provided with a plurality of probes 220 on the probe module 200 for pressing the battery; a power module 300, connected to the press 100 and electrically connected to the probe module 200; a docking component 400, arranged on the press 100, and electrically connected to the probe module 200 and the power module 300, respectively, and the docking component 400 is used to dock with an external cabinet 20 through an independent connecting line.

[0047] It can be understood that the press 100, as the main structure of the mechanical unit 10, can support the battery and drive it to rise and fall during the process of chemical division and capacity formation, so that the battery can be accurately positioned to the contact position of the probe 220 and complete the pressing contact with the probe 220; the probe module 200 is fixedly connected to the press 100, for example, it can be arranged at the top of the battery lifting area and connected to the press 100, and the probe module 200 includes a plurality of probes 220, and the plurality of probes 220 are arranged in pairs, that is, the positive probe and the negative probe are arranged in pairs, and can realize current input and output after pressing the battery cell to perform charging and discharging operations; the power supply module 300 is electrically connected to the probe module 200 to provide the probe with high-precision charging and discharging current. It can be arranged above the probe module 200 and fixed on the press to reduce line loss.

[0048] The docking component 400 is a key component for connecting the mechanical unit 10 to the external cabinet 20. The docking component 400 is arranged on the press 100 and is connected to the wiring harnesses led out of the probe module 200 and the power module 300 respectively. During the assembly process, the sampling lines, signal lines, power lines and other wires of the probe module 200 and the power module 300 can be electrically connected to the docking component 400 in the press 100 to form a modular mechanical unit 10. Then, an independent connecting line is used to dock the cabinet 20 with the docking component 400. In this way, the mechanical unit 10 The wires of components such as the probe module 200 and the power module 300 on the cabinet 20 no longer need to be connected one by one, which greatly shortens the wiring time of a single device and effectively improves the assembly efficiency. Since there are only independent connecting lines between the mechanical unit 10 and the cabinet 20, there is no need to remove a large number of cables during maintenance. Only the connecting lines connected to the docking component 400 need to be disconnected. When adding a new functional module to the mechanical unit 10, there is no need to rewire between the mechanical unit 10 and the cabinet 20, which effectively improves the convenience of maintenance and the expansion performance.

[0049] It should be clear that in the embodiment of the present application, the press machine 100 may have one or more mounting positions for the probe module 200 and the power module 300, for example Figure 1 As shown, the press machine 100 can have three installation positions for the probe module 200 and the power module 300 (only the case of installing the power module 300 in one installation position is shown in the figure); the probe module 200 and the power module 300 correspond in quantity, for example, the probe module 200 and the power module 300 can both be one, or both can be multiple of the same quantity.

[0050] refer to Figure 2In order to further improve the assembly efficiency of the mechanical unit 10, in some embodiments, a sampling adapter plate 210 is connected to the probe module 200, and the sampling adapter plate 210 is connected to the docking component 400 through a signal line; a plurality of probes 220 are arranged at intervals on one side of the sampling adapter plate 210 along the length direction of the sampling adapter plate 210, and are respectively connected to the sampling adapter plate 210 through a wiring harness.

[0051] The sampling adapter plate 210 can be a circuit board integrated into the probe module 200. Multiple probes 220 are arranged at intervals on one side of the sampling adapter plate 210 along the length direction of the sampling adapter plate 210. The multiple probes 220 are linearly arranged with a fixed spacing to ensure precise alignment with the battery tabs. All probes 220 are located on the same side of the sampling adapter plate 210. The sampling adapter plate 210 is directly connected to the sampling adapter plate 210 through a short line, so that the sampling adapter plate 210 can centrally manage the sampling signals of all probes 220. As a result, the length of the probe sampling line can be shortened, and the connection between the probe 220 and the sampling adapter plate 210 is pre-welded before assembly. The mechanical unit 10 assembly site only needs to plug a single signal harness into the docking component 400, which effectively reduces the assembly time and effectively improves the assembly efficiency. It also makes the probe module 200 in the mechanical unit 10 highly modular, which is more conducive to expansion and maintenance.

[0052] It should be understood that in conventional technology, the sampling lines of multiple probes 220 are generally led out independently, and all the sampling lines of the probes 220 are integrated into a harness. In the embodiment of the present application, the sampling adapter plate 210 is connected to the probe module 200, and all the probes 220 are connected to the sampling adapter plate 210 in turn. Finally, the sampling adapter plate 210 leads out the signal harness and is plugged into the docking component 400 of the press 100. Therefore, the length of the sampling line is shortened, and there is only a small section between the probe 220 and the sampling adapter plate 210, and the assembly efficiency is significantly improved.

[0053] refer to Figure 2 In terms of the optimization of the power supply module 300, in some embodiments, the power supply module 300 includes: a power adapter plate 310, which is connected to the press 100 and connected to the docking component 400 through a power line and a signal line; a plurality of DCDC power supply modules 320, which are correspondingly arranged on the top of the plurality of probes 220 and are arranged at intervals on one side of the power adapter plate 310 along the length direction of the power adapter plate 310; each DCDC power supply module 320 is connected to the power adapter plate 310 through a wiring harness, and is electrically connected to the positive and negative poles of the adjacent probes 220.

[0054] The power modules 300 are arranged at intervals in the top space of the probe module 200 and are fixedly connected to the press 100. In each power module 300, multiple DCDC power modules 320 are arranged linearly at a fixed interval and are arranged at intervals on one side of the power adapter board 310 along the length direction of the power adapter board 310. Each DCDC power module 320 has a pair of positive and negative probes 220 at the bottom, and each pair of positive and negative probes 220 is connected to the DCDC power module 320 at the top through a braided wire. All DCDC power modules 320 are connected to the power adapter board 310 on the side, and the power adapter board 310 then leads out the power line and signal line to connect to the docking component 400, thereby reducing the number of wires and improving assembly efficiency.

[0055] refer to Figure 2 In order to dissipate heat from the power module 300 on the press 100, in some embodiments, the mechanical unit 10 further includes a fan module 500, which includes: a fan mounting plate 510, arranged between the probe module 200 and the power module 300 and connected to the press 100; a plurality of fans 520, arranged at intervals along the length direction of the fan mounting plate 510, and connected to the fan mounting plate 510; a fan adapter plate 530, arranged on one side of the plurality of fans 520 and connected to the press 100, the fan adapter plate 530 being connected to the docking component 400 via a power cord, and each fan 520 being connected to the fan adapter plate 530 via a wiring harness.

[0056] It should be noted that the wires of each fan in the fan assembly in traditional technology are independent, while the fan assembly on the press will leave multiple fan wire ends, which need to be plugged into the cabinet one by one to realize the power supply of the fan. In the present application, each fan module 500 in the press 100 is arranged between the corresponding probe module 200 and the power module 300, and multiple fans 520 are connected to the fan mounting plate 510 and correspond to the multiple DCDC power modules 320 on the top. Therefore, during the assembly process, multiple fans 520 are first assembled as a whole on a fan mounting plate 510, and the wire ends are concentrated on the fan adapter plate 530. All fans 520 are integrated and connected, and then the fan adapter plate 530 is used to lead out the power harness. This power harness is plugged into the docking component 400 of the press 100, wherein the fan mounting plate 510 and the fan adapter plate 530 are both installed on the press 100. Therefore, during assembly, only the single power cord of the fan adapter plate 530 needs to be plugged into the docking component 400 on site, the wiring process is reduced, and the maintenance cost is significantly improved.

[0057] To enable speed regulation of the fan 520, in some embodiments, the fan module 500 further includes a speed regulating box 540, which is connected to the press 100 and to the fan adapter plate 530 via a speed regulating harness. The speed regulating box 540 is connected to the fan adapter plate 530 via the speed regulating harness, eliminating the need to connect the speed regulating harnesses to each fan 520 separately. This enables speed regulation of the fan 520 while reducing the number of speed regulating harnesses and improving assembly efficiency.

[0058] refer to Figure 1 and Figure 3 In some embodiments, a temperature acquisition module 600 is further included. The temperature acquisition module includes multiple temperature acquisition probes 610. The multiple temperature acquisition probes 610 are connected side by side with the corresponding multiple probes 220 on one side of the multiple probes 220; wherein each temperature acquisition probe 610 is connected to the corresponding DCDC power module 320 via a sampling line. In the embodiment of the present application, the temperature acquisition module 600 is designed to correspond to the number of probe modules 200. In each temperature acquisition module 600, the multiple temperature acquisition probes 610 are installed side by side with the corresponding multiple probes 220 to collect the temperature of the battery after heating; each temperature acquisition probe 610 is directly connected to the corresponding DCDC power module 320 via a sampling line. The DCDC power module 320 has an integrated temperature acquisition function, which can perform data acquisition, eliminating the need for a temperature box and saving equipment space.

[0059] Some embodiments provide another different layout of the temperature acquisition module 600, that is, the temperature acquisition module 600 also includes a temperature box 620, the temperature box 620 is connected to the press 100, and each temperature acquisition probe 610 is connected to the temperature box 620 via a temperature line, that is, temperature data can also be collected through the temperature box 620.

[0060] refer to Figures 1 to 3 As shown, in some embodiments, the press 100 includes a lifting frame 110, at least one mounting plate 120 and a fixed frame 130; the lifting frame 110 is connected to the fixed frame 130 and can support the battery for lifting and lowering movements, and the probe module 200 and the power supply module 300 are both connected to the fixed frame 130; an inspection area is provided on the fixed frame 130, the mounting plate 120 is arranged in the inspection area and is connected to the fixed frame 130; the docking component 400 is provided on the mounting plate 120.

[0061] The fixed frame 130 in the embodiment of the present application is composed of an upper frame and a lower frame, and a plurality of guide columns and support columns arranged vertically are designed between the upper frame and the lower frame, wherein the probe module 200 and the power module 300 are both connected to the upper frame of the fixed frame 130, and the lifting frame 110 is installed on the guide columns. The upper frame is provided with a drive motor, which is connected to the lifting frame 110 to drive the lifting frame 110 to move up and down along the guide columns so that the battery can be pressed by the probe 220. The fixed frame 130 is provided with an inspection area, which is located at the rear of the press 100. The mounting plate 120 is arranged in the inspection area and is respectively connected to the upper frame and the lower frame of the fixed frame 130; the docking component 400 is provided on the mounting plate 120 for easy inspection.

[0062] refer to Figure 1 In some embodiments, the temperature box 620 and the speed regulating box 540 are both mounted on the mounting plate 120 , and the mounting plate 120 provides greater convenience for the installation, storage, and maintenance of these components.

[0063] In some embodiments, the mechanical unit 10 also includes a sensor module, which includes at least one of a CO sensor, a smoke sensor, or a displacement sensor, all of which are installed on the press 100, and are connected to the docking component 400 through a wiring harness terminal. All sensors are directly connected to the docking component 400 through standardized wiring harness terminals. The time required for accessing a single sensor is significantly shortened. When a sensor fails, there is no need to shut down and disassemble structural parts, which reduces maintenance costs. New sensors can be plug-and-play, which facilitates expansion.

[0064] In some embodiments, the docking component 400 includes a quick-plug connector and / or a terminal block. The docking component 400 mainly provides a power interface and / or a signal interface to achieve power docking and / or signal docking with the cabinet 20. The docking component 400 can select a quick-plug connector and a terminal block to achieve power docking, and the docking component 400 can select a terminal block to achieve signal docking. In addition, when the docking component 400 in the embodiment of the present application is a quick-plug connector (for example, a plug-and-play quick-plug connector), it is a quick-plug female connector, and both ends of the independent connection line adapted therewith are quick-plug male connectors, and the interface at one end of the cabinet is also a quick-plug female connector, so as to achieve quick plug-in and unplugging of the independent connection line relative to the docking component 400 and the cabinet 20.

[0065] refer to Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the assembly of the mechanical unit and cabinet in the battery charging and discharging device provided in an embodiment of the present application; Figure 5 This is a schematic diagram of the overall structure of the battery charging and discharging equipment provided in an embodiment of the present application.

[0066] Another embodiment of the present application provides a battery charging and discharging device 1000, including at least one mechanical unit 10 and a cabinet 20 as described above; the cabinet 20 includes an electrical cabinet 21 and at least one distribution box 22, and the distribution box 22 is connected to the electrical cabinet 21; a distribution component is encapsulated in the distribution box 22, and a matching component connected to the distribution component is provided on the distribution box 22, so as to be connected to the docking component 400 of the mechanical unit 10 through an independent connecting line during assembly.

[0067] In the embodiment of the present application, the cabinet 20 includes an electrical cabinet 21 and one or more distribution boxes 22. The distribution boxes 22 are fixedly connected to the electrical cabinet 21. The electrical cabinet 21 can supply power to the distribution boxes 22. The distribution boxes 22 are encapsulated with conventional power distribution components such as a PLC control module and a voltage conversion module. The selection of the power distribution components can be based on the requirements of the mechanical unit 10. This is something that can be obtained by those skilled in the art without any creative effort and is therefore not described in detail. The matching components on the distribution box 22 can be located at the bottom of the housing of the distribution box 22 so as to connect to the docking components 400 of the mechanical unit 10 via independent connecting lines during assembly.

[0068] It should be understood that in conventional technology, electrical components and wire ducts are conventionally provided on the cabinet body, but in the present application, the corresponding distribution components of a mechanical unit 10 are encapsulated in a distribution box 22, and the distribution box 22 is provided with input and output quick-plug connectors, and the quick-plug connectors can be selected as heavy-duty connectors, so that the wire ducts can be eliminated, and the electrical components are directly installed in the distribution box 22.
