Description

Technical Field

[0001] This application relates to the field of lithium battery production equipment, and in particular to a formation device and a formation cabinet. Background Technology

[0002] Battery formation, a crucial step in battery manufacturing, involves activating the positive and negative electrode materials within the battery using specific charging and discharging methods in formation equipment. This process forms a stable solid electrolyte interphase (SEI) film, thereby improving the battery's cycle life, safety, and electrochemical performance.

[0003] Traditional formation equipment typically comprises two main functional areas: a battery testing area and a power module installation area. The battery testing area is equipped with positive and negative electrode probe assemblies and fixing mechanisms for physically securing the battery cells and performing charge / discharge operations. The power module installation area houses the power module, which is electrically connected to the positive and negative electrode probes in the battery testing area via cables to supply power for battery charging and discharging. During battery formation, the battery testing area needs to maintain a high temperature of 45°C to meet the battery formation temperature requirements, while the power module, due to the temperature resistance limitations of its electronic components, must be kept at a normal temperature below 25°C. To avoid temperature interference, the two areas are usually isolated in different locations, resulting in long electrical connection cables between the power module and the probe assembly. This leads to higher costs, increased power loss, and a larger footprint for the formation equipment.

[0018] Compared with the prior art, the chemical formation equipment and chemical formation cabinet provided in this application have at least the following advantages:

[0019] This application employs a modular structural design for the formation equipment. The formation equipment includes a power supply unit and a probe assembly, which are respectively arranged in a power supply housing space and a battery testing space for housing the battery to be formed, formed along a first direction. The probe assembly is used to perform a compression test on the battery in the battery testing space.

[0045] As for the foregoing, the general concept of this application embodiment is to provide a formation device 10. By designing a power supply device 200 with a heat-insulating enclosure 210, the power module 220 is isolated from the external high-temperature environment. Furthermore, a first temperature control component 230 is set inside the heat-insulating enclosure 210 to ensure that the power module 220 inside the power supply device 200 can operate in a normal temperature environment, while the external battery can be formed at a higher temperature. Since the power module 220 is isolated from the external high-temperature environment, the power supply housing space R1 can be located near the battery testing space R2 to shorten the electrical connection distance between the power module 220 and the probe assembly 100, reduce cable costs and transmission losses, and reduce the overall space occupied by the device through a compact spatial layout.

[0046] Based on the above concept, and referring to Figures 1 to 6As shown, this application embodiment provides a formation device 10, which has a power supply housing space R1 and a battery testing space R2 for housing a battery to be formed along a first direction H. The formation device 10 includes: a probe assembly 100 disposed in the battery testing space R2; and a power supply device 200, including: a heat insulation box 210 disposed in the power supply housing space R1, the heat insulation box 210 forming an independent temperature control chamber 210A; a power module 220 disposed in the independent temperature control chamber 210A, the power module 220 being electrically connected to the probe assembly 100; and a first temperature control component 230 disposed in the independent temperature control chamber 210A for maintaining the operating temperature in the independent temperature control chamber 210A below the external ambient temperature of the power supply device 200.

[0047] It should be noted that in the embodiments of this application, the first direction H is the height direction of the formation device 10, the second direction D is the width direction of the formation device 10, and the third direction L is the length direction of the formation device 10. The first direction H, the second direction D, and the third direction L are perpendicular to each other.

[0048] It should be understood that in the embodiments of this application, the power supply housing space R1 and the battery testing space R2 are distributed vertically in the first direction H, that is, the power supply housing space R1 and the battery testing space R2 are adjacent, and the power supply housing space R1 can be located on top of the battery testing space R2; the power supply device 200 is located in the power supply housing space R1, the battery can be formed in the battery testing space R2, and the probe assembly 100 is disposed in the battery testing space R2, directly contacting the electrode of the battery to be formed, so as to realize the electrical conduction between the power module 220 and the battery, which helps to shorten the electrical connection distance between components, reduce cable costs and transmission losses, and reduce the overall space occupied by the equipment through a compact spatial layout.

[0049] The structural design of the power supply unit 200 is crucial for meeting the low-temperature requirements of the power module 220 and the high-temperature requirements of the battery formation environment. The power supply unit 200 mainly consists of a heat-insulating enclosure 210, a power module 220, and a first temperature control component 230. Both the power module 220 and the first temperature control component 230 are arranged inside the heat-insulating enclosure 210. Specifically, the heat-insulating enclosure 210 can be a rectangular enclosure made of heat-insulating materials. The independent temperature control chamber 210A formed by the heat-insulating enclosure 210 can effectively isolate the external high-temperature environment. The power module 220 is protected from high temperatures. The power module 220 is directly or shortly connected to the probe assembly 100 through the heat insulation box 210 via an electrical connection cable to provide power for the formation. The first temperature control assembly 230 can maintain the temperature of the independent temperature control chamber 210A below the external environment (i.e., the temperature of the battery test space R2) through heat dissipation methods such as water cooling or air cooling, ensuring that the power module 220 works stably below 25°C, so as to achieve compatibility between the high-temperature formation environment of the battery in the formation equipment 100 and the low-temperature working environment of the power module 220.

[0050] refer to Figure 2 To further improve the heat exchange capacity within the power supply device 200, in some embodiments, the power supply device 200 further includes a duct support 233, which is arranged within an independent temperature control chamber 210A and forms a receiving cavity 233A; the first temperature control component 230 includes a heat exchanger 231 and a fan 232, the heat exchanger 231 is arranged within the independent temperature control chamber 210A and mounted on the duct support 233, the fan 232 is arranged within the receiving cavity 233A and mounted on the duct support 233, and the fan 232 is located between the heat exchanger 231 and the power module 220 in the first direction H; the power module 220 is mounted on the duct support 233 and stacked and spaced apart from the heat exchanger 231, and the power module 220 is arranged in the receiving cavity 233A.

[0051] In this embodiment, the air duct support 233 is arranged within the independent temperature-controlled chamber 210A, serving as a core component for support and airflow guidance. Its interior forms a receiving cavity 233A to accommodate the fan 232 and the power module 220. The heat exchanger 231 is mounted on the air duct support 233, located within the independent temperature-controlled chamber 210A, and is responsible for absorbing heat from the chamber. The fan 232 is arranged within the receiving cavity 233A of the air duct support 233, positioned along the first direction H between the heat exchanger 231 and the power module 220, driving directional airflow. The power module 220 is mounted on the air duct support 233. The power module 220 is stacked and spaced apart with the heat exchanger 231, and is completely contained within the housing cavity 233A to ensure concentrated airflow coverage. Thus, the heat generated by the power module 220 during operation is transferred to the air duct support 233 and the heat exchanger 231 through heat conduction. After the fan 232 is started, the airflow first passes through the heat exchanger 231, which transfers the heat to the external cooling system (such as cooling water) through water cooling circulation. After being accelerated by the fan 232, the cooled airflow flows directly over the surface of the power module 220, carrying away its residual heat and enabling the power module 220 to maintain a low temperature during operation.

[0052] In some embodiments, the receiving cavity 233A is connected to the independent temperature control chamber 210A; one end of the air duct support 233 along the first direction H is fixed to the inner wall of the heat insulation box 210, and the rest is spaced apart from the inner wall of the heat insulation box 210, so that the airflow after heat exchange by the heat exchanger 231 can circulate between the receiving cavity 233A and the independent temperature control chamber 210A through the gap.

[0053] Figure 2 The dashed arrows indicate the airflow circulation path. The air duct support 233 is arranged in the independent temperature control chamber 210A. One end of the air duct support 233 along the first direction H can be directly fixed to the inner wall of the heat insulation box 210, while the rest is spaced apart from the inner wall of the heat insulation box 210, so as to facilitate the circulation of gas between the independent temperature control chamber 210A and the receiving chamber 233A through the spaced part. The air duct support 233 not only provides support for the fixation of the first temperature control component 230 and the power module 220, but also forms a double heat insulation structure through its structural design in conjunction with the heat insulation box 210, which further enhances the isolation effect of the power module 220 from the external high temperature environment. After the fan 232 is started, the airflow flows out from the power module 220 and flows back to the inlet of the heat exchanger 231 through the space between the air duct support 233 and the inner wall of the heat insulation box 210 (except for the fixed end), forming a closed loop, which effectively suppresses the temperature rise of the power module 220.

[0054] It should be noted that the air duct bracket 233 integrates support and airflow guiding functions, which helps reduce the number of independent components and saves space in the independent temperature control chamber 210A, making the power supply unit 200 more compact to match the arrangement of the high-density power modules 220. Ventilation holes can be provided on the air duct bracket 233 to facilitate gas circulation between the independent temperature control chamber 210A and the receiving chamber 233A. Through the structural design of the air duct bracket 233, heat exchanger 231, fan 232, and power module 220, the heat exchange capacity of the power supply unit 200 is significantly improved, ensuring stable operation of the power module 220 at lower temperatures, while optimizing space utilization and energy consumption.

[0055] In some embodiments, the heat insulation enclosure 210 is provided with a heat insulation layer 211 made of glass fiber composite polypropylene material. For example, the heat insulation enclosure 210 may be composed of an outer shell layer covering an inner shell layer, with the inner shell layer forming an independent temperature-controlled chamber 210A. There is a space between the outer shell layer and the inner shell layer, and the space is filled with a heat insulation layer 211 made of glass fiber composite polypropylene material, so as to significantly improve the heat insulation performance of the heat insulation enclosure 210, thereby ensuring efficient isolation between the external high-temperature environment and the power module 220.

[0056] In some embodiments, heat exchanger 231 is a water-cooled heat exchanger. Compared with air-cooled heat exchangers, water-cooled heat exchangers use water as a cooling medium, have a higher energy efficiency ratio, and can save energy and reduce operating costs.

[0057] refer to Figures 3-5 In order to install the power supply device 200 and the probe assembly 100, in some embodiments, the formation device 10 further includes a mounting bracket 300 disposed along a first direction H between the probe assembly 100 and the heat insulation box 210, and connected to the heat insulation box 210 and the probe assembly 100 respectively.

[0058] The mounting bracket 300 directly connects the probe assembly 100 and the power supply unit 200 along the first direction H, making them spatially close to each other. The electrical connection lines between the power module 220 and the probe assembly 100 can be arranged along a short distance inside or on the surface of the mounting bracket 300, significantly reducing cable length.

[0059] In some embodiments, the mounting bracket 300 includes a first support 310, a second support 320, and a plurality of first support columns 330; the first support 310 and the second support 320 are arranged at intervals along a first direction H, and the first support columns 330 are arranged between the first support 310 and the second support 320 along the first direction H, and the two ends of the first support columns 330 along the first direction H are respectively connected to the first support 310 and the second support 320; the first support 310 is disposed on the battery to be formed along the first direction H and is connected to the probe assembly 100, and the second support 320 is connected to the power supply device 200.

[0060] In this embodiment, the first support 310 can serve as the boundary between the power supply housing space R1 and the battery testing space. The first support 310 is located at the bottom of the second support 320 and is spaced apart from the second support 320 along the first direction H. Multiple first support columns 330 are connected to both sides between the first support 310 and the second support 320. The first support 310 serves as a fixing base for the probe assembly 100, ensuring precise connection between it and the positive and negative terminals of the battery. The second support 320 can be located at the bottom of the power supply housing space R1 and the battery testing space. Within the space R1, and serving as the fixed end of the power supply device 200, it can be tightly connected to the heat insulation box 210 by bolts or clips to prevent electrical connection loosening due to vibration; multiple first support columns 330 are arranged at intervals along the first direction H between the first support member 310 and the second support member 320; each support column is rigidly connected to the first support member 310 and the second support member 320 at both ends along the first direction H to form a stable frame structure, providing stable support for the probe assembly 100 and the power supply device 200.

[0061] refer to Figure 4 As shown, in order to further realize temperature control in the formation device 10, in some embodiments, the formation device 10 further includes a second temperature control component 400. The second temperature control component 400 is connected to the first support 310 and is located between the power supply device 200 and the probe component 100 along the first direction H, so as to exchange heat with the battery to be formed.

[0062] The second temperature control component 400 can be multiple fans arranged at intervals along the third direction L. The second temperature control component 400 is fixed on the top of the first support 310 and located between the power supply device 200 and the probe component 100. The second temperature control component 400 exchanges heat with the surface of the battery to be formed through hot air circulation, responds quickly to temperature changes, and ensures that the temperature around the battery is evenly distributed at about 45°C.

[0063] refer to Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the formation device 10 further includes a support frame 500, which forms a battery testing space R2 and a power supply housing space R1 that are interconnected; the mounting bracket 300 is slidably connected to the support frame 500 and is configured to simultaneously send the probe assembly 100 and the power supply device 200 into or out of the support frame 500.

[0064] In this embodiment, the battery testing space R2 and the power supply housing space R1 are integrated into a connected structure by the support frame 500, reducing cable redundancy and heat interference caused by spatial dispersion in traditional equipment, shortening the electrical connection distance between the probe assembly 100 and the power module 220, thereby reducing cable costs and transmission losses. The probe assembly 100, the power supply device 200, and the second temperature control component 400 are formed into an integral module by the mounting bracket 300. The sliding design of the mounting bracket 300 enables modular loading and unloading of the probe assembly 100, the power supply device 200, and the second temperature control component 400. Operators can complete the simultaneous loading / unloading of multiple components with a single slide, thereby significantly improving loading, unloading, and maintenance efficiency.

[0065] In some embodiments, the support frame 500 includes a guide support layer 510, a guide connecting post 520, a base support layer 530, and a movable support layer 540; the guide support layer 510, the movable support layer 540, and the base support layer 530 are stacked sequentially and spaced apart along a first direction H, and the guide connecting post 520 is connected to the guide support layer 510 and the base support layer 530; the guide support layer 510 is used to support the mounting frame 300 and is slidably connected to the mounting frame 300, and the movable support layer 540 is used to support the battery to be formed and is slidably connected to the guide connecting post 520, so as to drive the battery to be formed to move closer to or away from the probe assembly 100.

[0066] The guide support layer 510 is a fixed structure of the mounting frame 300. A power receiving space R1 is formed on its top. The mounting frame 300 is slidably connected to the top of the guide support layer 510 and can be pulled and pulled along the third direction L on the guide support layer 510. The guide support layer 510 is located on top of the movable support layer 540, and the base support layer 530 is located at the bottom of the movable support layer 540. Multiple guide connecting posts 520 are connected between the guide support layer 510 and the base support layer 530, and the movable support layer 540 is slidably connected to the guide connecting posts 520. When the mounting frame 300 is sent into the power receiving space R1 of the support frame 500, the bottom end of the probe assembly 100 on the mounting frame 300 is located at the bottom of the guide support layer 510. The movable support layer 540 can support the battery to be formed and move it closer to or away from the probe assembly 100 in the first direction H so as to achieve the pressing of the probe assembly 100 and the battery.

[0067] refer to Figure 5 As shown, in some embodiments, a guide rail 511 is provided on the guide support layer 510, and the mounting bracket 300 is slidably connected to the guide rail 511. For example, the guide rail 511 can be a linear guide rail. The cooperation between the guide rail 511 and the mounting bracket 300 can reduce sliding friction, ensure that the mounting bracket 300 is smoothly fed in / out, and avoid loose electrical connections or damage to components due to shaking.

[0068] In some embodiments, the formation device 10 further includes a drive mechanism 550, which is disposed on the guide support layer 510 and connected to the movable support layer 540 to drive the battery to be formed to move through the movable support layer 540; the drive mechanism 550 may specifically be a combination of a cylinder and a transmission rod system.

[0069] refer to Figure 6 As shown, in some embodiments, the formation device 10 further includes a guide frame 600, which is disposed on the guide support layer 510. The guide frame 600 includes a plurality of second support columns 610 arranged at intervals along the second direction D. The plurality of second support columns 610 are used to divide the space on the guide support layer 510 into a plurality of subspaces. Each subspace is provided with a mounting frame 300, and the guide support layer 510 is provided with a plurality of guide rails 511 along the second direction D for the plurality of mounting frames 300, so that the plurality of probe assemblies 100 and the corresponding power supply devices 200 can be simultaneously fed into or out of the support frame 500.

[0070] In this embodiment, the guide frame 600 divides the guide support layer 510 into multiple subspaces (e.g., 3 subspaces) through the second support column 610. Each subspace can independently accommodate a mounting frame 300, enabling the synchronous formation of multiple battery groups and significantly improving production capacity. Multiple guide rails 511 are arranged parallel to each other along the second direction D, supporting the synchronous sliding of multiple mounting frames 300, avoiding mutual interference, ensuring the independence of multi-station operation, and allowing for the replacement of a single mounting frame 300 module in a subspace during maintenance without stopping the entire equipment, thus improving production continuity.
