Description

Battery activation process equipment

[0001] The present invention relates to a battery activation process facility, and more specifically, to a battery activation process facility capable of effectively discharging heat from charging and discharging devices.

[0002] This application claims priority to Korean Patent Application No. 10-2024-0014068, filed on January 30, 2024, and all contents disclosed in the specification and drawings of the said application are incorporated by reference into this application.

[0003] Secondary battery production is largely divided into pre-process and post-process. The pre-process includes the electrode process, which creates the positive and negative electrode plates, and the assembly process, which processes and assembles the electrodes and raw materials to create the finished product. The activation process, which activates the battery's polarity through alternating charging and discharging, and the life testing, which calculates the battery's lifespan, capacity, and efficiency, are post-processes.

[0004] Immediately after assembly, batteries are essentially inert, possessing only a form. Activation involves charging and discharging the battery to impart electrical properties. An aging process allows the positive and negative electrodes to be fully impregnated with electrolyte. After repeated cycles, degassing, which removes internal gases if necessary (but only for pouch batteries), is performed. After completing these processes, the batteries are tested for internal resistance and open-circuit voltage, and a final grade is assigned before the cells are shipped.

[0005] Meanwhile, during the conventional battery activation process, there is a problem that the temperature of the charging / discharging device increases due to the heat generated by the large number of batteries charged / discharged, thereby reducing the charging / discharging efficiency. Furthermore, activating a large number of battery cells simultaneously requires a large number of charging / discharging devices. If the heat generated by these charging / discharging devices is not properly dissipated, problems such as deterioration of the quality of the battery cells, problems with smooth charging / discharging, or device defects that prevent the activation process from continuing may occur.

[0006] Accordingly, a method is required to effectively dissipate the heat generated by battery cells in the power supply during the battery activation process.

[0007] The present invention was created to solve the above problems, and its primary purpose is to provide a battery activation process facility capable of effectively dissipating heat generated from a plurality of charging and discharging devices.

Therefore, it should be understood that the embodiments described in this specification and the configurations illustrated in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical idea of ​​the present invention, and various equivalents and modifications may exist as of the time of this application.

[0035] In the drawings, the sizes of each component or specific parts of that component are exaggerated, omitted, or schematically illustrated for convenience and clarity of explanation. Therefore, the size of each component does not entirely reflect its actual size. If a detailed description of a related known function or configuration is deemed to unnecessarily obscure the gist of the present invention, such description will be omitted.

[0036] The term 'joint' or 'connection' as used herein includes not only cases where one member is directly joined or directly connected to another member, but also cases where one member is indirectly joined or indirectly connected to another member through a connecting member.

[0037] FIG. 1 is a drawing schematically showing the main configuration of a battery activation process facility according to one embodiment of the present invention, FIG. 2 is a drawing schematically showing the configuration of a charging / discharging device according to one embodiment of the present invention, FIG. 3 is a drawing showing a part of the battery activation process facility of FIG. 1, and FIG. 4 is a drawing schematically showing a charging / discharging device and a duct module according to one embodiment of the present invention in isolation.

[0038] Referring to these drawings, a battery activation process equipment (10) according to one embodiment of the present invention includes a plurality of charge / discharge devices (100) arranged in a horizontal direction (X direction) and a vertical direction (Z direction), and a duct module (200) connected to the charge / discharge devices (100) to provide cold air to the charge / discharge devices (100) or to remove heat from the charge / discharge devices (100).

[0039] The above charging / discharging device (100) may be configured to include a jig unit (110), a power supply unit (120), and an outer case (130).

[0040] The above jig unit (110) is a part that charges and discharges battery cells (B), and may include a charging and discharging jig (111) that receives power from a power supply unit (120) and charges the battery cells (B) or transmits the discharge current of the battery cells (B) to the power supply unit (120), and a cell tray (114) for storing the battery cells (B).

[0041] The above cell tray (114) can be configured to store and transport battery cells (B) as a whole. The battery cells (B) are loaded into the charging / discharging device (100) while stored in the cell tray (114), and are repeatedly charged / discharged. When activation is completed through charging / discharging, they can be removed from the charging / discharging device (100). At this time, the cell tray (114) can be transported by a stacker crane (not shown) that can move along the arrangement direction of the charging / discharging devices (100). The charging / discharging jig (111) will be described later for convenience of explanation.

[0042] The power supply unit (120) may include a power supply unit that supplies power to the charge / discharge jig (111). The power supply unit may include a main board (122) and a channel board (123), and the main board (122) may be configured to include an AC / DC converter or a DC / DC converter that rectifies and compresses power from an external power system and transmits it to the channel board (123) or vice versa. The channel board (123) receives power from the main board (122) and supplies it to the battery cell (B) or transmits power to the main board (122) when the battery cell (B) is discharged. The channel board (123) may be configured to include a DC / DC converter for converting the power supplied from the main board (122) to suit the charge / discharge characteristics of the battery cell (B).

[0043] The power supply unit (120) may further include a power circuit breaker (121). The power circuit breaker (121) is a component that functions to block overcurrent. The power circuit breaker (121), the main board (122), the channel board (123), and the charge / discharge jig (111) may be electrically connected by connecting members (C1, C2, C3) such as cables.

[0044] Each charging / discharging device (100) can be configured to receive power from an external distribution / distribution board, convert the power in accordance with the charging / discharging characteristics of the battery cell (B) in the power supply unit (120), and supply it to the jig unit (110), or vice versa.

[0045] The above outer case (130) is a component that can store or combine the jig part (110) and the power part (120) inside.

[0046] Within the above-described outer case (130), it is preferable that the jig unit (110) and the power unit (120) be housed in physically separated spaces. For example, when charging and discharging battery cells (B), heat may be generated in the jig unit (110) or a fire may occur due to abnormal heat generation of the battery cells (B). In this case, it is safe and advantageous for fire suppression for the power unit (120) to be placed in a space separate from the jig unit (110). Meanwhile, since heat generation from the power unit (120) may affect the battery cells (B) being charged and discharged, it is preferable that the jig unit (110) and the power unit (120) be placed in a space that is as thermally separated as possible.

[0047] The above-mentioned outer case (130) may be provided with a ventilation hole (132, 133) on at least one side to remove heat from the jig section (110) and / or the power supply section (120). The ventilation hole (132, 133) may be configured to communicate directly with the duct module (200).

[0048] The above-mentioned outer case (130) may be configured to be stacked in the form of a roughly rectangular parallelepiped frame, cabinet, or box. In other words, a plurality of outer cases (130) may be stacked vertically on top of each other, and, although not shown in detail, may be configured to be mutually fixedly connected using, for example, bolts or the like.

[0049] A battery activation process facility (10) including such a charging and discharging device, as shown in FIGS. 1 and 3, may include charging and discharging device groups (10A, 10B, 10C...) in which charging and discharging devices (100) are stacked in a vertical direction (Z direction) to a predetermined height. The charging and discharging device groups (10A, 10B, 10C...) may be arranged along a horizontal direction (X direction).

[0050] The duct module (200) may be arranged between the charging and discharging device groups (10A, 10B, 10C...) arranged in a horizontal direction. That is, the duct module (200) may be arranged alternately with the charging and discharging device groups (10A, 10B, 10C...) along the horizontal direction. In addition, the duct modules (200) may be connected to at least one integrated pipe (300). The integrated pipe (300) may be arranged above the charging and discharging device groups (10A, 10B, 10C...) as shown in FIG. 1.

[0051] The above integrated pipe (300) communicates with the duct modules (200) and may extend, for example, to the outside of the factory (where the battery activation process equipment (10) is constructed). Meanwhile, the integrated pipe (300) is not an essential component and may be omitted. That is, the battery activation process equipment (10) according to the present invention may be configured to exhaust or supply air only using the duct module (200) without using the integrated pipe (300).

[0052] Below, the connection configuration between the duct module (200) and each charging / discharging device (100) will be described in more detail.

[0053] As illustrated in FIG. 3, for example, the duct module (200) disposed between two adjacent charging and discharging device groups (10B, 10C) may be configured to communicate with the ventilation holes of the charging and discharging devices (100) forming the two charging and discharging device groups (10B, 10C).

[0054] To this end, the duct module (200) may include a duct body (210) and a plurality of connecting portions (220), as illustrated in FIG. 4. The duct body (210) may be configured to extend along the stacking direction (Z direction) of the charging and discharging devices (100) and to be in close contact with the outer surface of each charging and discharging device group. In addition, the plurality of connecting portions (220) may be connected to the ventilation holes (132, 133) of the charging and discharging devices (100). For example, the ventilation holes (132, 133) may be configured to be at least partially fitted into the connecting portions (220) of the corresponding duct body (210). The plurality of connecting portions (220) may be provided at predetermined intervals along the extending direction of the duct body (210) to correspond to the ventilation holes (132, 133) of the vertically stacked charging and discharging devices (100).

[0055] According to this configuration, the operating temperature of the charging and discharging devices (100) can be appropriately maintained by supplying cooling air to each charging and discharging device (100) through the duct module (200) or by extracting heat from each charging and discharging device (100) through the duct module (200).

[0056] More specifically, referring mainly to FIG. 5 together with FIG. 3 to FIG. 4, the duct body (210) includes a plurality of direct pipes (211a to 215a, 211b to 215b) therein, and the plurality of direct pipes (211a to 215a, 211b to 215b) can be configured to be connected one-to-one with the plurality of connecting portions (220).

[0057] The stacked charging and discharging devices (100) are connected to the respective ventilation holes (132, 133) of the corresponding connecting portions (220) of the duct module (200), and the connecting portions (220) are individually connected to different direct pipes (211a to 215a, 211b to 215b). Accordingly, the heat generated in each charging and discharging device (100) can be individually exhausted along the respective corresponding direct pipes (211a to 215a, 211b to 215b). Therefore, the temperature of the charging and discharging devices (100) can be managed more efficiently.

[0058] In addition, according to the plurality of direct pipes (211a to 215a, 211b to 215b), cooling air can be individually provided to each charging / discharging device (100) and heat can be extracted from each charging / discharging device (100).

[0059] As shown in FIGS. 2 and 4, the outer case (130) according to the present embodiment has a covering plate (131) that partitions the jig part (110) and the power unit (120) inside and is provided to allow ventilation, and the jig part (110) and the power unit (120) can be arranged on the left and right sides with the covering plate (131) therebetween. In addition, the ventilation holes (132, 133) provided in the outer case (130) may include a first ventilation hole (132) on the left side (134), which corresponds to the outer side facing the covering plate (131), with the jig part (110) therebetween, and a second ventilation hole (133) on the right side (135), which corresponds to the outer side facing the covering plate (131), with the power unit (120) therebetween.

[0060] Referring to FIGS. 3 and 4 together, duct modules (200) are arranged on the left and right sides of the charging and discharging device (100), respectively, with respect to the charging and discharging device (100), and the first ventilation hole (132) of the charging and discharging device (100) can be connected to the connection part (220) of the left-side duct module (200), and the second ventilation hole (133) of the charging and discharging device (100) can be connected to the connection part (220) of the right-side duct module (200).

[0061] With reference to the above duct module (200), charging and discharging devices (100) are arranged on the left and right sides of the duct module (200), respectively, and the second ventilation holes (133) of the left-side charging and discharging devices (100) can be connected to the left-side connecting portions (220) of the duct module (200), and the first ventilation holes (132) of the right-side charging and discharging devices (100) can be connected to the right-side connecting portions (220) of the duct module (200).

[0062] And referring to FIG. 5, the second ventilation holes (133) of the left-side charging and discharging devices (100) may be configured to communicate one-to-one with some of the direct pipes (211b to 215b) among the plurality of direct pipes accommodated inside the duct module (200), and the first ventilation holes (132) of the right-side charging and discharging devices (100) may be configured to communicate one-to-one with the remaining direct pipes (211a to 215a) among the plurality of direct pipes.

[0063] Here, among the plurality of direct pipes, the direct pipes (211a to 215a) connected to the first ventilation holes (132) can be used as supply pipes for supplying cooling air, and the direct pipes (211b to 215b) connected to the second ventilation holes (133) can be used as exhaust pipes for removing heat.

[0064] That is, the battery activation process equipment (10) according to the present invention may be configured such that the charging and discharging device groups (10A, 10B, 10C...) and the duct modules (200) are alternately arranged, and the ventilation holes (132, 133) of the charging and discharging devices (100) are connected to the duct module (200) as described above. According to this implementation configuration, each charging and discharging device (100) allows cooling air to be introduced into the outer case (130) through the direct pipes (211a to 215a) used as the air supply pipes and the first ventilation hole (132), and the cooling air can absorb the heat of the jig unit (110) and the power supply unit (120). And the heat accumulated inside the outer case (130) can be discharged to the outside of the battery activation process equipment (10) through the second ventilation hole (133) and the direct pipes (211b to 215b) used as the exhaust pipe.

[0065] Next, with reference to FIG. 6 and FIG. 7 along with FIG. 2, the connection configuration between the charging / discharging jig (111) of the charging / discharging device (100) and the power supply (120) will be examined.

[0066] As described above, the charging / discharging device (100) according to one embodiment of the present invention has a cover plate (131) that is provided to allow ventilation and partition the jig portion (110) and the power unit (120) within the outer case (130), and the jig portion (110) and the power unit (120) can be arranged on the left and right sides with the cover plate (131) between them.

[0067] The above jig (110) may include a charging / discharging jig (111) and a cell tray (114).

[0068] The above charging / discharging jig (111) may include a positive electrode jig (112) connected to the positive electrode of the battery cells (B) and a negative electrode jig (113) connected to the negative electrode of the battery cells (B).

[0069] Referring to FIG. 6, the positive electrode jig (112) includes positive electrode grippers (112a) that make one-to-one contact with the positive electrodes (leads) of the battery cells (B). The positive electrode grippers (112a) may be provided in a roughly clamp-like shape capable of clamping the positive electrodes (leads) of the battery cells (B). This embodiment schematically shows an example of the positive electrode grippers (112a). The positive electrode grippers (112a) may have any shape as long as they can maintain a stable contact state with the positive electrodes (leads) of the battery cells (B). Although not shown for convenience of the drawing, the positive electrode grippers (112a) may be connected one-to-one with the positive electrode terminals of the channel boards (123) of the power supply unit (120), and at this time, the positive electrode grippers (112a) and the positive electrode terminals of the channel boards (123) may be connected by power cables (C3).

[0070] The above-described negative electrode jig (113) includes negative electrode grippers (113a) that make one-to-one contact with the negative electrodes (leads) of the battery cells (B). The negative electrode grippers (113a), like the positive electrode grippers (112a), may be provided in a roughly clamp-like shape capable of clamping the negative electrodes (leads) of the battery cells (B). The shape of the negative electrode gripper (113a) of the present embodiment is shown as an example. That is, the negative electrode gripper (113a) may have any shape as long as it can stably maintain contact with the negative electrodes (leads) of the battery cells (B).

[0071] Meanwhile, the negative electrode jig (113) according to one embodiment of the present invention may further include a gripper negative electrode bus bar (113b). The gripper negative electrode bus bar (113b) may be provided in the form of a rod or plate as a metal material having electrical conductivity. In addition, the gripper negative electrode bus bar (113b) may be configured to be connected to each negative electrode gripper (113a), as illustrated in FIG. 7. In this case, the negative electrode grippers (113a) are electrically connected in parallel, and the voltages at the negative electrode grippers (113a) may be equal potential. The gripper negative electrode bus bar (113b) may be connected to the channel board negative electrode bus bar (124) (see FIG. 2).

[0072] The above-mentioned channel board negative bus bar (124) is a connecting member that is formed in the form of a bar or plate made of a metal material having electrical conductivity and extends from the jig section (110) to the power section (120). The above-mentioned channel board negative bus bar (124) may be provided in an insulated form with its surface wrapped with an insulating film or an insulating tube.

[0073] The above-mentioned channel board negative bus bar (124) can have one side connected to the gripper negative bus bar (113b) in the jig section (110) and the other side connected to the negative terminals of a plurality of channel boards (123) in the power supply section (120). In this way, by connecting the negative grippers (113a) and the negative terminals (not shown) of the channel board (123) using the gripper negative bus bar (113b) and the channel board negative bus bar (124), a plurality of power cables can be omitted. According to this configuration, the amount of power cables used can be reduced, which reduces line resistance, thereby reducing voltage drop and energy loss and reducing heat generation.

[0074] Next, with reference to FIGS. 8 to 10, a battery activation process facility (10) according to other embodiments of the present invention will be briefly described. The same member numbers as those of the aforementioned embodiments represent the same members, and duplicate descriptions of the same members will be omitted, with the differences from the aforementioned embodiments being primarily described.

[0075] Referring to FIG. 8, a battery activation process equipment (10) according to another embodiment of the present invention includes a charging / discharging device (100) in which a jig unit (110) and a power supply unit (120) are vertically arranged inside an outer case (130), unlike the above-described embodiment.

[0076] The above charging / discharging device (100A) has a covering plate (131) that is provided to allow ventilation and partition the jig portion (110) and the power supply portion (120) within the outer case (130). The covering plate may be provided in a grating structure so as to be horizontal to the ground and allow ventilation. Based on the covering plate (131), the jig portion (110) may be placed above the covering plate (131) and the power supply portion (120) may be placed below the covering plate (131).

[0077] The above charging / discharging device (100A), compared to the charging / discharging device (100) of the above-described embodiment, can individually provide cooling air to the jig unit (110) and the power supply unit (120) and remove heat, so that the cooling efficiency for the charging / discharging devices (100A) can be increased compared to the above-described embodiment.

[0078] Specifically, referring to FIGS. 8 and 9, the ventilation hole (132) of the charging / discharging device (100) according to the present embodiment includes an upper first ventilation hole (132a) located above the cover plate (131) and provided on the left side of the jig part (110) and an upper second ventilation hole (133a) provided on the right side of the jig part (110). In addition, the ventilation hole (132) further includes a lower first ventilation hole (132b) located below the cover plate (131) and provided on the left side of the power supply part (120) and a lower second ventilation hole (133b) provided on the right side of the power supply part (120).

[0079] The upper first ventilation hole (132a) and the lower first ventilation hole (132b) may be configured to be connected to the duct module (200) arranged on the left side of the charging / discharging device (100), and the upper second ventilation hole (133a) and the lower second ventilation hole (133b) may be configured to be connected to the duct module (200) arranged on the right side of the charging / discharging device (100).

[0080] The above duct module (200) has no substantial structural difference compared to the embodiment of FIG. 4 described above, except for the number and location of the direct pipes. That is, the duct module (200) has a plurality of direct pipes inside and can be placed between two vertically stacked charging and discharging groups.

[0081] And among the plurality of direct pipes, the direct pipes connected to the upper first ventilation hole (132a) and the lower first ventilation hole (132b) of the charging / discharging device (100) located on the right side of the duct module (200) are used as supply pipes for supplying cooling air, and the direct pipes connected to the upper second ventilation hole (133a) and the lower second ventilation hole (133b) of the charging / discharging device (100) located on the left side of the duct module (200) can be used as exhaust pipes for removing heat. In this pattern, the charging / discharging device groups (10A, 10B, 10C, 10D) and the duct module (200) according to another embodiment of the present invention can be alternately arranged, as shown in FIG. 10.

[0082] According to this configuration, the jig unit (110) of each charging / discharging device (100) can receive cooling air through the duct module (200) provided on the left side and the upper first ventilation hole (132a), and can remove heat through the upper second ventilation hole (133a) and the duct module (200) provided on the right side. In addition, separately from the jig unit (110), the power supply unit (120) of each charging / discharging device (100) can receive cooling air through the duct module (200) provided on the left side and the lower first ventilation hole (132b), and can remove heat through the lower second ventilation hole (133b) and the duct module (200) provided on the right side. Therefore, according to this embodiment configuration, the cooling efficiency of each charging / discharging device (100) can be further increased and heat transfer between the jig unit (110) and the power supply unit (120) can be minimized.

[0083] As described above, the battery activation process equipment according to the present invention can effectively dissipate heat generated from multiple charging and discharging devices. In particular, the battery activation process equipment according to the present invention can independently discharge heat from each charging and discharging device through a duct module, thereby more effectively and quickly maintaining the appropriate temperature of each charging and discharging device.
