The embodiments described below by referring to the drawings are exemplary and are only used to explain the utility model and cannot be understood as limiting the utility model.

Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used in the specification of the template herein are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0046] In the related art, the battery formation cabinet uses a liquid cooling system for temperature control. The liquid cooling system uses the characteristics of high specific heat capacity of the cooling fluid to take away the heat generated by the battery, and has high heat dissipation efficiency and good comprehensive performance. However, since the cooling pipeline of the liquid cooling system cannot be in close contact with the battery, it is only arranged on the outer periphery of the battery formation tray, and the battery formation trays are stacked, there is a situation of uneven temperature distribution, which is not conducive to improving the quality of battery formation.

[0047] As Figure 1As shown, to solve the above technical problems, the battery formation tray provided by the embodiments of the present application includes a tray body 400 having a bearing surface with a heat dissipation area 420 and a battery placement area 450, the battery placement area 450 being located on the periphery of the heat dissipation area 420, the heat dissipation area 420 of the tray body 400 being provided with at least one heat dissipation hole 430, and the battery placement area 450 having a plurality of battery 1100 placement stations arranged in sequence on the periphery of the heat dissipation area 420, the battery 1100 placement station being used for placing a battery 1100.

[0048] In these embodiments, the present application aims to optimize temperature management during the battery 1100 formation process, particularly to solve the problem of uneven temperature distribution in the conventional liquid cooling system. The specific composition and working principle of the battery formation tray are as follows:

[0049] The tray body 400 has a bearing surface, that is, an end surface for bearing the battery 1100, usually the end surface of the tray body 400 facing upward, and the bearing surface is divided into a heat dissipation area 420 and a battery placement area 450. Among them, the heat dissipation area 420 is arranged at the center position of the bearing surface and is provided with at least one heat dissipation hole 430. The role of these heat dissipation holes 430 is to promote air circulation and help heat to be dissipated more effectively. In this way, the gas flowability inside the entire tray can be improved, thereby improving the uniformity of temperature distribution.

[0050] For example, in the present embodiment, the number of heat dissipation holes 430 is 1, and when the number of heat dissipation holes 430 is 1, the inner diameter of the heat dissipation hole 430 should be appropriately increased, such as covering the entire heat dissipation area 420, which is conducive to air circulation and heat dissipation. Of course, in other embodiments, the number of heat dissipation holes 430 can also be 2, 3, 4, 5, 6, or 7, etc., which is not limited here.

[0051] In addition, the battery placement area 450 is located around the heat dissipation area 420 and includes a plurality of battery 1100 placement stations for placing the battery 1100. These battery 1100 placement stations are arranged in sequence around the heat dissipation area 420, ensuring that each battery 1100 can benefit from the improved air flow path, which helps to maintain a relatively consistent working temperature. Among them, the battery 1100 placement station is configured to stably accommodate a single battery 1100 and maintain the position of the battery 1100 during the formation process. Such a layout is not only conducive to heat management, but also ensures the safety and efficiency of the operation.

[0052] It should be noted that since the plurality of battery 1100 placement sites are arranged on the circumferential side of the heat dissipation area 420, there is a gap between the batteries 1100 placed in the battery 1100 placement sites. The gap facilitates the flow of gas between the heat dissipation holes 430 and the battery 1100 gap, further facilitating temperature uniformity.

[0053] Obviously, during the formation of the battery 1100, the battery 1100 will release heat due to chemical reactions. Although the traditional liquid cooling system can carry away part of the heat, the cooling pipeline cannot directly contact the battery 1100, resulting in uneven temperature distribution. By arranging the heat dissipation holes 430 in the heat dissipation area 420 of the disc body 400, the present application increases the air convection between the upper and lower trays, so that the heat can be dispersed faster and more uniformly. This not only improves the heat dissipation efficiency, but also improves the temperature consistency in the entire formation cabinet. More uniform temperature distribution means that all batteries 1100 complete formation under similar conditions, which is crucial for improving the consistency and overall performance of the battery 1100.

[0054] As shown in Figure 1 In some embodiments, the battery formation tray further includes an inner side plate 410 and a plurality of circuit control modules. The inner side plate 410 is arranged on the bearing surface, and the inner side plate 410 extends along the circumferential direction of the heat dissipation area 420. The plurality of circuit control modules are arranged one-to-one corresponding to the plurality of battery 1100 placement sites. The circuit control module has a conductive contact, and the conductive contact is arranged on the side of the inner side plate 410 away from the bearing surface. The conductive contact is used to contact and conduct with the tab 1110 of the battery 1100 located in the corresponding battery 1100 placement site.

[0055] In these embodiments, the battery formation tray is additionally provided with an inner side plate 410, which not only enhances the functionality of the tray, but also improves the safety and efficiency of the battery 1100 formation process.

[0056] The inner side plate 410 is arranged on the bearing surface, i.e. the inner side plate 410 is located on the bearing surface, and the inner side plate 410 is arranged along the circumferential direction of the heat dissipation area 420. The inner side plate 410 is arranged around the heat dissipation area 420 to form a closed or semi-closed space. It should be noted that the main function of the conductive contact on the outer side of the inner side plate 410 is to electrically connect with the tab 1110 (i.e. the positive and negative electrode contacts of the battery 1100) of the battery 1100 placed in the battery 1100 placement site. That is, this design allows current to be directly conducted to the corresponding battery 1100 through the conductive contact, ensuring the stability and reliability of the current path.

[0057] Since the conductive contacts are usually made of materials with good electrical conductivity, the contact resistance can be reduced, the electrical conductivity efficiency of the entire system can be improved, and thus the quality of the battery 1100 formation can be improved. Furthermore, for the batch battery 1100 formation process, the design of the inner side plate 410 simplifies the installation and disassembly process of the battery 1100, and improves the work efficiency.

[0058] Moreover, since the inner side plate 410 is close to the battery 1100, it can also play a certain heat dissipation role, helping to quickly transfer the heat generated by the battery 1100, and cooperating with the heat dissipation holes 430 to optimize the heat management performance of the entire tray.

[0059] Furthermore, the present device can introduce an overheat protection, a leakage detection and an automatic shutdown system to improve the safety of the device and an intelligent fan control system to adjust the fan speed in real time according to the temperature of the device to achieve the best heat dissipation effect and energy efficiency. It should be noted that the overheat protection, the leakage detection and the automatic shutdown system are conventional settings in the art, and will not be described in detail here.

[0060] Exemplarily, in the present embodiment, the inner side plate 410 and the disc body 400 are integrally arranged. Of course, in other embodiments, the inner side plate 410 and the disc body 400 are arranged by welding, or the inner side plate 410 and the disc body 400 are arranged by detachable connection, such as bolt fixing, screw fixing, etc.

[0061] In addition, each battery 1100 placement station is provided with a corresponding circuit control module, so that each battery 1100 has an independent constant current and constant voltage source, and each battery 1100 channel can be independently controlled to achieve precise charge and discharge management.

[0062] Exemplarily, the conductive contacts include positive and negative contacts to respectively connect the positive and negative tabs 1110 of the battery 1100.

[0063] As shown in Figure 1 In some embodiments, the inner side plate 410 has a plurality of structural segments, and the plurality of structural segments are sequentially connected in the circumferential direction of the heat dissipation area 420. The side of each structural segment away from the bearing surface is arranged as a plane, and the plurality of structural segments and the plurality of battery 1100 placement stations correspond one by one.

[0064] In these embodiments, the inner side plate 410 is configured to have a plurality of structural segments, and the plurality of structural segments are sequentially connected in the circumferential direction of the heat dissipation area 420. The side of each structural segment away from the heat dissipation area 420 is arranged as a plane, optimizing the functionality and applicability of the battery formation tray.

[0065] That is, the inner side plate 410 is composed of multiple structural segments, which are connected in sequence along the circumference of the heat dissipation area 420 to form a complete annular or partial annular structure. The side of each structural segment away from the heat dissipation area 420 is designed as a plane, which means that this side is parallel to other components on the bearing surface (such as the battery 1100 placement station), providing a flat and regular contact surface, which helps to increase the stability of the conduction between the battery 1100 and the conductive contacts on the inner side plate 410, making the connection between other electrical components more direct and stable, reducing the need for complex connectors, and facilitating installation and subsequent maintenance.

[0066] In addition, the design of multiple structural segments allows the inner side plate 410 to better adapt to batteries 1100 of different sizes or shapes, improving the support capability of the tray for various types of batteries 1100.

[0067] For example, the number of structural segments can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or 11, etc., which is not limited here, and can be set according to actual application requirements.

[0068] In addition, the multiple structural segments and the multiple battery 1100 placement stations are one-to-one corresponding, that is, the tab 1110 of the battery 1100 placed on the battery 1100 placement station and the conductive contact on the side of the corresponding structural segment away from the bearing surface are in contact and conduction.

[0069] As shown in Figure 1 In some embodiments, the compression device presses the disc body 400 downward so that the battery 1100 and the tab 1110 on each layer of the disc body 400 are compressed and fixed in alignment by the upper disc body 400.

[0070] As shown in Figure 1 In some embodiments, the inner side plate 410 is arranged in an annular structure, and the heat dissipation area 420 is located in the area surrounded by the inner side plate 410, so that the side of the inner side plate 410 away from the heat dissipation area 420 forms a regular polygonal structure.

[0071] In these embodiments, the inner side plate 410 is configured in an annular structure, and the heat dissipation area 420 is located in the area surrounded by the inner side plate 410, so that the side of the inner side plate 410 away from the heat dissipation area 420 forms a regular polygonal structure.

[0072] The inner side plate 410 is annular as a whole, surrounding the heat dissipation area 420 in the center of the tray, ensuring that each battery 1100 placement station is evenly distributed around it. The side of the inner side plate 410 away from the heat dissipation area 420 forms a regular polygonal structure, which means it is not completely circular, but has multiple flat segments, which can be optimized according to the specific layout of the battery 1100 placement station.

[0073] The regular polygonal structure can better adapt to the placement station of batteries 1100 of different shapes and sizes, maximizing the use of tray space and improving equipment flexibility. Furthermore, the gap between adjacent batteries 1100 gradually increases in the direction away from the inner side plate 410, which facilitates increased gas flow.

[0074] Furthermore, the regular polygonal structure provides more planar contact surfaces, which helps to ensure a stable connection between the battery 1100 tabs 1110 and other electrical components, reducing the risk of loosening or poor contact. The annular inner plate 410 can form a closed current loop, ensuring that the current is evenly distributed among all batteries 1100, improving the consistency of the formation process. The annular structure surrounds the heat dissipation area 420, enhancing the effect of air convection, while the planar portion of the regular polygonal structure also facilitates rapid heat transfer, improving heat dissipation efficiency.

[0075] Furthermore, since the inner side plate 410 is arranged around the heat dissipation area 420, it can serve as an additional heat dissipation path, helping to dissipate the heat generated by the battery 1100 more evenly and avoid local overheating.

[0076] For example, a regular polygon structure can be a regular triangular shape, a regular quadrilateral, a regular pentagon, a regular hexagon, a regular heptagon, etc.

[0077] like Figure 1 As shown, in some embodiments, the battery 1100 placement station on the bearing surface has a positioning mark 440, which is used to indicate the placement position of the battery 1100, so that the tab 1110 of the battery 1100 and the inner side plate 410 make contact and conduction.

[0078] In these embodiments, the battery 1100 placement station on the bearing surface has positioning marks 440, which are used to accurately indicate the placement position of the battery 1100 to ensure that the tabs 1110 of the battery 1100 can accurately contact and conduct with the inner side plate 410.

[0079] Each battery 1100 placement station has a clear positioning mark 440, which can typically be a physical mark (such as a groove, raised area, or positioning line), color code, or graphic symbol, to guide the correct placement of the battery 1100. The positioning mark 440 is designed to ensure that the tabs 1110 (positive and negative contacts) of the battery 1100 can be aligned with the conductive contacts on the inner side plate 410 to achieve a reliable electrical connection.

[0080] It is clear that by providing clear placement guidelines, the positioning mark 440 reduces the problem of poor connection caused by the operator misplacing the battery 1100, ensuring that each battery 1100 is correctly connected to the circuit. Moreover, the correct placement position makes the contact between the battery 1100 tab 1110 and the inner side plate 410 more compact, reducing the contact resistance, improving the current transmission efficiency, and enhancing the reliability of the entire system. Especially for batch processing battery 1100 formation tasks, the positioning mark 440 simplifies the installation process of the battery 1100, improves work efficiency, and reduces the probability of error.

[0081] Furthermore, since all batteries 1100 are placed according to the specified position, the current can be evenly distributed among all batteries 1100, helping to maintain a consistent working temperature and improve the quality of battery 1100 formation. Good electrical connection reduces unnecessary heat generation, reduces the risk of local overheating, and prolongs the service life of the battery 1100.

[0082] For example, in this embodiment, the positioning mark 440 is set as a positioning line, and the positioning line of each battery placement area 450 is parallel to the side of the corresponding structure section facing away from the heat dissipation area 420.

[0083] In some embodiments, each of the battery 1100 placement stations is configured with a station number.

[0084] In these embodiments, not only does it help improve the accuracy and efficiency of the operation, but it also provides convenience for management and tracking during the battery 1100 formation process. Each battery 1100 placement station has a unique station number, usually represented in numbers, letters, or combinations. The station number should be designed to be easily identifiable and can be fixed on the bearing surface through printing, engraving, or labeling, etc. to ensure that the operator can quickly find the corresponding station.

[0085] The station number allows the position of each battery 1100 to be accurately located and recorded, facilitating the management and tracking of the battery 1100 during the entire formation process. Through clear numbering guidance, the operator can place the battery 1100 more quickly in the correct position, reducing the probability of error and improving work efficiency.

[0086] When processing batteries 1100 in batches, the station number can help the factory better plan the production schedule and arrange different batches or types of batteries 1100 for formation, improving the flexibility and response speed of production.

[0087] Furthermore, when a certain battery 1100 needs to be inspected or maintained, the station number makes it easier to locate, reduces the search time, and improves the efficiency of maintenance. Optionally, in combination with an automated system or recording tool (such as a barcode scanner), the station number can be used to establish a detailed battery 1100 formation file, supporting quality control and problem tracking.

[0088] In addition, if a certain battery 1100 placement station has a problem, the station number can help quickly locate and solve the problem, avoiding affecting the formation effect of other batteries 1100.

[0089] In some embodiments, the circuit control module has a circuit board, the circuit board and the conductive contact are electrically connected, and the circuit board is arranged on one side of the inner side plate 410 close to the heat dissipation area 420.

[0090] In these embodiments, the circuit board is placed near the middle of the disc body 400. Since the circuit board no longer occupies external space, the internal space can be fully utilized, the number of battery 1100 placement stations can be increased, and the layout is more reasonable.

[0091] As shown in Figure 2 , Figure 3 and Figure 4 , some embodiments of the present application also provide a battery formation cabinet, which comprises a cabinet body 300 and a tray group. The cabinet body 300 has a formation cavity 310, and the tray group comprises a plurality of battery formation trays according to any one of the above embodiments. The plurality of battery formation trays are stacked in the formation cavity 310 of the cabinet body 300, and the heat dissipation holes 430 of the plurality of battery formation trays are arranged in communication. In addition, uniform style LED alarm light strips 330 are assembled on the upper and lower ends of the outer surface of the cabinet body 300, which can provide visual alarm when the equipment is running abnormally. Moreover, PTEE is used as an insulating material in the cabinet body to protect the key parts of the electronic equipment, ensuring the safety of the electrical appliances and the stability of the equipment. Safety signs can be added (designed) in the later actual use to ensure the safety of the workers.

[0092] In these embodiments, the present application not only covers the improved battery formation tray, but also provides a battery formation cabinet containing these trays. This battery formation cabinet realizes more efficient heat management and temperature distribution uniformity by stacking a plurality of optimized battery formation trays in the formation cavity 310 of the cabinet body 300 and ensuring that the heat dissipation holes 430 of these trays are arranged in communication.

[0093] Cabinet body 300 and formation cavity 310: The battery formation cabinet is composed of a solid cabinet body 300, which has a formation cavity 310 inside for placing battery formation trays. The design of the formation cavity 310 takes into account the maximum space utilization, which can accommodate a plurality of stacked battery formation trays.

[0094] Tray assembly: The tray assembly includes multiple battery formation trays as described in any of the above embodiments, each tray being specially designed to optimize heat dissipation and electrical connections. Multiple battery formation trays can be vertically stacked within the formation chamber 310 to form a multi-layer structure, increasing the number of batteries 1100 that can be processed in a single operation.

[0095] The heat dissipation holes 430 of each tray are interconnected, forming a continuous airflow path from bottom to top, which helps to quickly dissipate heat. The interconnected heat dissipation holes 430 ensure uniform airflow distribution throughout the formation chamber 310, avoiding local overheating and improving temperature uniformity.

[0096] Clearly, the interconnected heat dissipation vents 430 promote air convection, enhancing gas flow throughout the system and allowing heat to dissipate more quickly and evenly. This uniform airflow ensures that all batteries 1100 on all trays benefit from good heat dissipation, reducing temperature gradients and improving the quality and consistency of battery formation. Furthermore, the stackable tray design simplifies equipment installation and maintenance, facilitates batch processing of batteries 1100, and reduces space requirements.

[0097] For example, at least two guide posts are provided in the formation cavity 310. The guide posts extend in a preset direction, and the disk 400 is provided with a guide hole. The guide posts slide through the corresponding guide posts, thereby ensuring the neatness and coaxiality of the stack of multiple disks 400, and also helping to ensure the coaxiality of the heat dissipation holes 430 of the multiple disks 400, reducing the flow resistance of gas in the heat dissipation holes 430 of the multiple disks 400.

[0098] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, a heat dissipation gap is defined between the inner wall of the formation cavity 310 and the periphery of the battery formation tray.

[0099] In these embodiments, a heat dissipation gap is defined between the inner wall of the formation cavity 310 and the periphery of the battery formation tray. By adding an additional heat dissipation path, heat dissipation is further optimized, ensuring a more uniform temperature distribution.

[0100] In other words, a certain space is left between the inner wall of the formation chamber 310 and the periphery of the battery formation tray, forming a heat dissipation gap. This gap acts as an additional airflow channel, promoting air convection and enhancing the heat dissipation effect. Obviously, the heat dissipation gap provides an additional heat dissipation path, allowing heat to be discharged not only through the heat dissipation holes 430 on the tray, but also quickly dissipated through the gap, improving the overall heat dissipation efficiency.

[0101] Exemplarily, the formation cavity 310 is provided in a cylindrical shape, and the disc body 400 is provided in a circular shape, and the two are gap-fitted. It should be noted that generally, a square cabinet body 300 is divided into two formation areas, and only 4 battery 1100 placement points can be arranged on each side of one layer, and a total of 8 points are arranged on both sides. Such a layout not only has a small number of points, but also causes interference between the battery 1100 placement stations in actual operation, affecting the formation effect. In the present application, the cylindrical cabinet body 300 places the point electronic accessories uniformly at a position close to the middle of the disc body 400, that is, the inner side of the inner side plate 410, so that the internal space can be fully utilized, and the number of battery 1100 placement stations is increased. Since the electronic accessories no longer occupy the external space, the area of the battery 1100 placement points is significantly increased, and the layout is more reasonable.

[0102] By comparison, one layer of circular disc body 400 can accommodate more battery 1100 placement points, and compared with the square disc body 400, 4 more points can be arranged on each layer. Therefore, under the condition of the same number of layers, the total number of battery 1100 placement points of the cylindrical formation cabinet is obviously more, and the formation efficiency is improved.

[0103] Moreover, the space utilization of the cylindrical structure is higher, especially in the utilization of the internal space. Since the electronic accessories are uniformly distributed in the interior, the waste of the external space is reduced, so that more battery 1100 points can be arranged in the effective area.

[0104] Exemplarily, the cabinet body 300 is internally provided with 18 layers of disc bodies 400, each layer has 12 independent battery 1100 placement stations, and a total of 216 battery 1100 placement stations are arranged, which meets the high-density storage and processing requirements.

[0105] As shown in Figure 3 and Figure 5 In some embodiments, the formation cavity 310 has a preset direction, the preset direction is a vertical direction, and a plurality of battery formation trays are sequentially arranged in the preset direction.

[0106] The battery formation cabinet further comprises a pressing device, the pressing device comprises a pressing member 700 and a driving member, the driving member is arranged in the cabinet body 300, the pressing member 700 is connected with the driving member, the pressing member 700 is located above the tray group, and the driving member is used to drive the pressing member 700 to move along the preset direction, so that the pressing member 700 can extrude all the batteries 1100 on the uppermost disc body 400 in the preset direction; wherein the pressing member 700 has a communication hole 710, the communication hole 710 and the heat dissipation hole 430 are communicated, and the connection position of the driving member and the pressing member 700 is away from the communication hole 710.

[0107] In these embodiments, a pressing device is introduced to ensure that the batteries 1100 are subjected to uniform pressure during the formation process. In addition, the formation cavity 310 has a preset direction (vertical direction), which is also the stacking direction of the plurality of disc bodies 400, i.e., the plurality of battery formation trays are sequentially stacked along this direction.

[0108] The preset direction of the formation cavity 310 is the vertical direction, which means that the plurality of battery formation trays are sequentially stacked along the vertical direction. This arrangement maximizes the use of vertical space, increases the number of batteries 1100 processed at a time, improves production efficiency, and reduces the floor area occupied by the formation cabinet.

[0109] The plurality of battery formation trays are stacked along the vertical direction to form a multi-layer structure, facilitating batch processing of the batteries 1100. The heat dissipation holes 430 on each tray are interconnected, forming a continuous airflow path from the bottom to the top, enhancing the heat dissipation effect.

[0110] The extrusion member 700 is located above the tray group and is used to apply uniform pressure downward to all the batteries 1100 on the uppermost tray, thereby sequentially pressing all the batteries 1100 on all the disc bodies 400. The driving member is installed on the cabinet body 300 and is connected with the extrusion member 700, responsible for driving the extrusion member 700 to move along the vertical direction. The extrusion member 700 is provided with a communication hole 710 that communicates with the heat dissipation holes 430 on the tray, ensuring unobstructed airflow and maintaining good heat dissipation performance.

[0111] Obviously, through the pressing device, it can be ensured that each battery 1100 is subjected to uniform pressure, avoiding the problem of poor contact due to uneven placement or looseness, and improving the reliability of electrical connection. Applying appropriate pressure helps to achieve close contact between the tab 1110 of the battery 1100 and the inner side plate 410, reducing contact resistance and improving current transmission efficiency.

[0112] Appropriate pressing force can prevent the batteries 1100 from shifting during the formation process due to vibration or other reasons, ensuring the safety of the equipment and the quality of the batteries 1100.

[0113] For example, an adjustable pressure system is configured to allow adjustment of the applied pressure according to different types and needs of the batteries 1100, ensuring optimal contact effect. The extrusion member 700 is made of a material with good electrical conductivity and high temperature resistance to ensure optimal electrical connection and heat dissipation performance.

[0114] For example, the side of the extrusion member 700 facing the disc body 400 is the extrusion end face, which is parallel to the disc body 400 and can abut and press all the batteries 1100 on the disc body 400.

[0115] For example, the extrusion member 700 is provided with a plurality of extrusion protrusions 720, which are arranged in a staggered manner and can abut and press all the batteries 1100 on the disc body 400. Figure 5As shown, in some embodiments, the pressing member 700 is configured as a pressing disc, which is coaxially arranged with the disc body 400, and the communication holes 710 are arranged through the middle part of the pressing disc. The driving member includes the telescopic part 100 and at least two adapter parts 600. The telescopic part 100 has a fixed end 110 and a telescopic end 120, which can perform a telescopic action in a preset direction relative to the fixed end 110. The telescopic end 120 is connected with one end of the adapter part 600, and the other end of the adapter part 600 is connected with the pressing disc. The at least two adapter parts 600 are arranged along the circumference of the telescopic end 120, and the gap between any two adjacent adapter parts 600 is in communication with the communication holes 710. The connection between the at least two adapter parts 600 and the telescopic end 120 is uniformly distributed along the circumference of the telescopic end 120, and the connection between the at least two adapter parts 600 and the pressing disc is uniformly distributed along the circumference of the pressing disc.

[0116] In these embodiments, the pressing device adopts a specific pressing disc and driving member, which not only ensures that the battery 1100 receives uniform pressure during the formation process, but also enhances the heat dissipation effect and the reliability of operation by optimizing the structure. The following is a specific analysis of this design and its advantages:

[0117] The pressing disc is coaxially arranged with the disc body 400 of the tray set, ensuring that the pressure is uniformly distributed on the entire disc surface. The middle part of the pressing disc is provided with communication holes 710, which are in communication with the heat dissipation holes 430 on the tray, ensuring smooth airflow and maintaining good heat dissipation performance.

[0118] The driving member includes a fixed end 110 and a telescopic end 120, which can perform a telescopic action in the vertical direction (preset direction) to drive the pressing disc to move up and down. The at least two adapter parts 600 are arranged along the circumference of the telescopic end 120 and connected with the telescopic end 120 and the pressing disc. The design of the adapter part 600 ensures the stability of the pressing disc and the uniform distribution of pressure. The connections between the adapter part 600 and the telescopic end 120 and the pressing disc are uniformly distributed along the circumference, respectively, ensuring the symmetry and stability of the structure. Through coaxial arrangement and uniform connection of multiple adapter parts 600, the pressing disc can apply uniform pressure to all batteries 1100 on the uppermost tray, avoiding poor contact or damage caused by uneven local pressure.

The upper heat dissipation vent and the upper compartment are connected, and the lower heat dissipation vent 320 is connected to the lower compartment. Electronic components are respectively installed in the upper compartment and the lower compartment.

[0121] For example, a line terminal equipment 1000 is installed in the lower engine compartment, and the line terminal equipment 1000 is electrically connected to the circuit control module. Optionally, the circuit control module and the circuit control module are detachably connected, such as by plug-in connection, etc. A control panel 200, etc., is installed in the upper engine compartment, and the control panel 200 is electrically connected to the line terminal equipment 1000. A heat dissipation component 800, such as a radiator, fan, etc., is installed in the upper engine compartment.

[0122] In some embodiments, the battery formation cabinet also includes a dehumidifier 900, which is disposed in the cabinet body 300 and is used to dry the air inside the formation cabinet.

[0123] For example, in this embodiment, the dehumidifier 900 includes a drying box, which is connected to the formation chamber 310 through micropores, and the drying box is filled with a desiccant. Of course, in other embodiments, the dehumidifier 900 may also be a molecular sieve, etc.
