Description

Technical Field

[0001] This disclosure relates to battery activation process equipment, and more specifically, to battery activation process equipment capable of effectively dissipating heat generated from charging and discharging devices.

[0002] This application is based on and claims priority to Korean Patent Application No. 10-2024-0014068, filed with the Korean Intellectual Property Office on January 30, 2024, the disclosure of which is incorporated herein by reference in its entirety. Background Technology

[0003] The production of secondary batteries is mainly divided into pre-processing and post-processing. The electrode process, which involves making the positive and negative electrode plates, and the assembly process, which involves processing and assembling the electrodes and raw materials to produce the finished product, belong to the pre-processing. The activation process, which involves alternating charging and discharging to activate the battery polarity, and the life test, which calculates the battery's lifespan, capacity, and efficiency, belong to the post-processing.

[0004] A battery that has just undergone assembly only has form and may not be functional at all. It then goes through an activation process involving charging and discharging to impart electrical characteristics, an aging process to allow the positive and negative electrode materials to be fully impregnated with the electrolyte, and a degassing process (limited to pouch cells) to remove internal gases if necessary after repeating this process extensively. Only then does the battery acquire battery performance. For batteries that have undergone these processes, a final rating is given by checking internal resistance and open-circuit voltage, and the individual cells are then shipped.

[0005] Meanwhile, in traditional battery activation processes, as a large number of batteries are charged and discharged, the temperature of the charging and discharging devices rises due to the heat generated by the numerous batteries, leading to reduced charging and discharging efficiency. Furthermore, a large number of charging and discharging devices are required to simultaneously activate a large number of battery cells. If the heat generated from these devices is not properly dissipated, problems such as battery cell quality degradation, charging and discharging difficulties, or device defects may prevent the activation process from continuing.

[0006] Therefore, there is a need for a method that can effectively dissipate the heat generated by individual battery cells in the power section during battery activation. Summary of the Invention

[0039] As used herein, the term “connection” or “link” refers not only to the direct connection or linking of one component to another, but also to the indirect connection or linking of one component to another through a joining component.

[0040] Figure 1 This is a schematic view illustrating the main configuration of a battery activation process apparatus according to an embodiment of the present disclosure. Figure 2 This is a schematic view illustrating the configuration of a charging and discharging device according to one embodiment of the present disclosure. Figure 3 It is shown Figure 1 A view of a portion of the battery activation process equipment, and Figure 4 This is a view showing the charging and discharging device and the pipeline module separated from each other according to an embodiment of the present disclosure.

[0041] Referring to these figures, a battery activation process apparatus 10 according to an embodiment of the present disclosure includes: a plurality of charging and discharging devices 100 arranged in a horizontal direction (X direction) and a vertical direction (Z direction); and a conduit module 200 connected to the charging and discharging devices 100 to provide cold air to the charging and discharging devices 100 or remove heat from the charging and discharging devices 100.

[0042] The charging and discharging device 100 can be configured to include a clamping section 110, a power section 120, and a housing 130.

[0043] The clamping section 110 is the part for charging and discharging battery cell B, and may include a charging and discharging clamp 111 and a cell tray 114. The charging and discharging clamp 111 receives power from the power section 120 and charges the battery cell B or transmits the discharge current of the battery cell B to the power section 120. The cell tray 114 is used to store the battery cell B.

[0044] The individual cell tray 114 can be configured to integrally store and transport battery cells B. Battery cells B can enter the charging and discharging device 100 while stored in the individual cell tray 114 for repeated charging and discharging, and can be removed from the charging and discharging device 100 once activation is complete through the charging and discharging process. At this time, the individual cell tray 114 can be transported by a stacker crane (not shown) capable of moving along the arrangement direction of the charging and discharging device 100. For ease of description, the charging and discharging fixture 111 will be described later.

[0045] The power section 120 is the portion that supplies power to the charging and discharging fixture 111 and may include a power supply unit. The power supply unit may include a main board 122 and a channel board 123. The main board 122 may be configured to include an AC / DC converter or a DC / DC converter that rectifies and steps down power from an external power system and transmits the power to the channel board 123, and vice versa. The channel board 123 is used to receive power from the main board 122 and supply power to the battery cell B or transmit power to the main board 122 when the battery cell B is discharging. The channel board 123 may be configured to include a DC / DC converter for converting the power supplied from the main board 122 to match the charging and discharging characteristics of the battery cell B.

[0046] The power section 120 may also include a power circuit breaker 121. The power circuit breaker 121 is a component responsible for interrupting overcurrent. The power circuit breaker 121, the main board 122, the channel board 123, and the charging and discharging fixture 111 can be electrically connected by connecting components C1, C2, and C3, such as cables.

[0047] Each of the charging and discharging devices 100 can be configured to receive power from an external power distribution board and convert the power in the power section 120 to match the charging and discharging characteristics of the battery cell B, and supply power to the clamp section 110, or perform the reverse operation.

[0048] The housing 130 is a component capable of storing or connecting the clamp section 110 and the power section 120 therein.

[0049] Inside the housing 130, the clamping section 110 and the power section 120 are preferably housed in physically separate spaces. For example, when charging and discharging battery cell B, heat may be generated in the clamping section 110, or a fire may occur due to abnormal heat generation in battery cell B. In such cases, it is safe and advantageous for the power section 120 to be spaced apart from the clamping section 110 in a separate space for fire suppression. Simultaneously, since the heat generated by the power section 120 may affect the battery cell B that is being charged and discharged, it is preferable that the clamping section 110 and the power section 120 are arranged in thermally separated spaces as much as possible.

[0050] The housing 130 may have ventilation holes 132, 133 on at least one side surface to remove heat from the clamp section 110 and / or the power section 120. The ventilation holes 132, 133 may be configured to communicate directly with the duct module 200.

[0051] The housing 130 can be configured to be stacked in the form of a generally cubic frame, cabinet, or box. In other words, multiple housings 130 can be stacked on top of each other in the vertical direction and can be configured to be fixedly connected to each other using, for example, bolts, although not shown in detail.

[0052] like Figure 1 and Figure 3 As shown, the battery activation process equipment 10, which includes such charging and discharging devices, may include charging and discharging device groups 10A, 10B, 10C..., wherein the charging and discharging devices 100 are stacked to a predetermined height in the vertical direction (Z direction). The charging and discharging device groups 10A, 10B, 10C... may be arranged in the horizontal direction (X direction).

[0053] The conduit module 200 can be disposed among the charging and discharging device groups 10A, 10B, 10C... arranged horizontally. That is, the conduit module 200 can be alternately disposed with the charging and discharging device groups 10A, 10B, 10C... along the horizontal direction. Furthermore, the conduit module 200 can be connected to at least one integrated conduit 300. For example... Figure 1 As shown, the integrated conduit 300 can be positioned above the charging and discharging device groups 10A, 10B, 10C...

[0054] The integrated conduit 300 communicates with the conduit module 200 and can extend to the outside of, for example, a factory (where the battery activation process equipment 10 is constructed). Meanwhile, the integrated conduit 300 is not a necessary configuration and can therefore be omitted. That is, the battery activation process equipment 10 according to this disclosure can be configured to exhaust or supply air using only the conduit module 200, without using the integrated conduit 300.

[0055] The connection configuration between the pipeline module 200 and each charging and discharging device 100 will be described in more detail below.

[0056] like Figure 3 As shown, for example, a pipe module 200 disposed between two adjacent charging and discharging device groups 10B, 10C can be configured to communicate with the ventilation holes of the charging and discharging device 100 forming the two charging and discharging device groups 10B, 10C.

[0057] Therefore, the pipe module 200 may include a pipe body 210 and multiple connecting parts 220, such as Figure 4 As shown. The pipe body 210 can 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. Furthermore, the plurality of connecting portions 220 can be connected to the ventilation holes 132, 133 of the charging and discharging devices 100. For example, the ventilation holes 132, 133 can be configured to at least partially fit into the corresponding connecting portions 220 of the pipe body 210. The plurality of connecting portions 220 can be arranged at predetermined intervals along the extension direction of the pipe body 210 to correspond to the ventilation holes 132, 133 of the charging and discharging devices 100 stacked in the vertical direction.

[0058] According to this configuration, cooling air can be supplied to each of the charging and discharging devices 100 through the pipe module 200, or the heat of each of the charging and discharging devices 100 can be discharged through the pipe module 200 to maintain the appropriate operating temperature of the charging and discharging devices 100.

[0059] More specifically, the main reference Figure 5 as well as Figures 3 to 4 The pipe body 210 may include a plurality of direct pipes 211a to 215a, 211b to 215b, and the plurality of direct pipes 211a to 215a, 211b to 215b may be configured to be connected to the plurality of connection portions 220 in a one-to-one manner.

[0060] Each vent 132, 133 of the stacked charging and discharging devices 100 is connected to a connection portion 220 of the conduit module 200, and the connection portion 220 is connected to different direct pipes 211a to 215a, 211b to 215b. Therefore, the heat generated by each charging and discharging device 100 can be dissipated individually along the respective direct pipes 211a to 215a, 211b to 215b. Thus, the temperature of the charging and discharging devices 100 can be managed more effectively.

[0061] In addition, cooling air can be supplied to each charging and discharging device 100 individually according to the plurality of direct pipes 211a to 215a, 211b to 215b, and heat can be discharged from each of the charging and discharging devices 100.

[0062] like Figure 2 and Figure 4 As shown, the housing 130 according to this embodiment has a shielding plate 131, which divides the clamping section 110 and the power section 120 within the housing 130 and is configured to allow ventilation. The clamping section 110 and the power section 120 can be arranged on the left and right sides, respectively, with the shielding plate 131 as the boundary. Furthermore, the ventilation holes 132 and 133 provided in the housing 130 may include a first ventilation hole 132 provided on the left surface 134 and a second ventilation hole 133 provided on the right surface 135. The left surface 134 corresponds to the outer surface facing the shielding plate 131 across the clamping section 110, and the right surface 135 corresponds to the outer surface facing the shielding plate 131 across the power section 120.

[0063] Let's refer to each other. Figure 3 and Figure 4 Based on the charging and discharging device 100, pipe modules 200 are respectively provided on the left and right sides of the charging and discharging device 100. The first ventilation hole 132 of the charging and discharging device 100 can be connected to the connection part 220 of the left pipe 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 pipe module 200.

[0064] Based on the pipeline module 200, charging and discharging devices 100 are respectively provided on the left and right sides of the pipeline module 200. The second ventilation hole 133 of the left charging and discharging device 100 can be connected to the left connecting part 220 of the pipeline module 200, and the first ventilation hole 132 of the right charging and discharging device 100 can be connected to the right connecting part 220 of the pipeline module 200.

[0065] Furthermore, refer to Figure 5 The second vent 133 of the left charging and discharging device 100 can be configured to communicate one-to-one with some of the direct pipes 211b to 215b among the plurality of direct pipes housed inside the pipe module 200, and the first vent 132 of the right charging and discharging device 100 can be configured to communicate one-to-one with the remaining direct pipes 211a to 215a among the plurality of direct pipes.

[0066] Here, the direct pipes 211a to 215a connected to the first vent 132 can be used as supply pipes for supplying cooling air, and the direct pipes 211b to 215b connected to the second vent 133 can be used as exhaust pipes for removing heat.

[0067] In other words, the battery activation process apparatus 10 according to this disclosure can be configured such that charging and discharging device groups 10A, 10B, 10C... are alternately arranged with the piping module 200, and as described above, the ventilation holes 132, 133 of the charging and discharging devices 100 are connected to the piping module 200. According to this embodiment, in each charging and discharging device 100, cooling air can be introduced into the housing 130 through direct pipes 211a to 215a serving as air supply pipes and the first ventilation hole 132, and the cooling air can absorb heat from the clamp section 110 and the power section 120. Furthermore, the heat accumulated inside the housing 130 can be discharged to the outside of the battery activation process apparatus 10 along the second ventilation hole 133 and direct pipes 211b to 215b serving as discharge pipes.

[0068] Next, we will refer to Figure 6 and Figure 7 as well as Figure 2 This describes the connection configuration between the charging and discharging fixture 111 of the charging and discharging device 100 and the power section 120.

[0069] As described above, a charging and discharging device 100 according to an embodiment of the present disclosure has a shielding plate 131 that divides the clamping section 110 and the power section 120 within the housing 130 and allows ventilation. The clamping section 110 and the power section 120 may be arranged on the left and right sides with the shielding plate as the boundary.

[0070] The clamping section 110 may include a charging and discharging clamp 111 and a single tray 114.

[0071] The charging and discharging clamp 111 may include a positive clamp 112 connected to the positive terminal of the battery cell B and a negative clamp 113 connected to the negative terminal of the battery cell B.

[0072] refer to Figure 6 The positive electrode clamp 112 includes a positive electrode holder 112a that contacts the positive electrode (lead) of the battery cell B in a one-to-one manner. The positive electrode holder 112a can be configured in a generally clamp shape capable of holding the positive electrode (lead) of the battery cell B. This embodiment schematically illustrates an example of the positive electrode holder 112a. The positive electrode holder 112a can be of any shape, as long as it can maintain stable contact with the positive electrode (lead) of the battery cell B. Furthermore, although not shown for ease of drawing, each of the positive electrode holders 112a can be connected one-to-one to the positive terminal of the channel plate 123 of the power section 120, and in this case, the positive electrode holder 112a and the positive terminal of the channel plate 123 can be connected via a power cable C3.

[0073] The negative electrode clamp 113 includes a negative electrode holder 113a that contacts the negative electrode (lead) of the battery cell B in a one-to-one manner. The negative electrode holder 113a can be configured in a generally clamp shape capable of holding the negative electrode (lead) of the battery cell B, similar to the positive electrode holder 112a. The shape of the negative electrode holder 113a in this embodiment is shown as an example. That is, the negative electrode holder 113a can be of any shape, as long as it can maintain stable contact with the negative electrode (lead) of the battery cell B.

[0074] Additionally, according to one embodiment of this disclosure, the negative electrode clamp 113 may further include a clamping negative electrode busbar 113b. The clamping negative electrode busbar 113b may be in the form of a rod or plate made of a conductive metal material. Furthermore, the clamping negative electrode busbar 113b may be configured to connect to each of the negative electrode clamps 113a, such as... Figure 7 As shown. In this case, the negative electrode holder 113a is connected in parallel, and the voltage on the negative electrode holder 113a can be at the same potential. The negative electrode busbar 113b of this holder can be connected to the negative electrode busbar 124 of the channel plate (see...). Figure 2 ).

[0075] The SS channel plate negative busbar 124 is a connecting member that is made of a conductive metallic material in the form of a rod or plate, and extends from the clamp section 110 to the power section 120. The channel plate negative busbar 124 can be configured as an insulating form with its surface covered by an insulating film or insulating tube.

[0076] One side of the channel plate negative busbar 124 can be connected to the clamp negative busbar 113b in the clamp section 110, and the other side can be connected to the negative terminals of multiple channel plates 123 in the power section 120. Thus, by connecting the negative clamp 113a and the negative terminals (not shown) of the channel plates 123 using the clamp negative busbar 113b and the channel plate negative busbar 124, multiple power cables can be omitted. This configuration reduces the amount of power cable used, thereby reducing line resistance, which in turn reduces voltage drop and energy loss, and lowers the generated heat.

[0077] Next, refer to Figures 8 to 10 The following section will briefly describe the battery activation process apparatus 10 according to other embodiments of the present disclosure. Component reference numerals that are the same as those in the above embodiments denote the same components, therefore repeated descriptions of the same components will be omitted, and the differences from the above embodiments will be mainly described.

[0078] refer to Figure 8 Unlike the above embodiments, the battery activation process apparatus 10 according to another embodiment of the present disclosure includes a charging and discharging device (100A), wherein the clamping section 110 and the power section 120 are vertically disposed inside the housing 130.

[0079] The charging and discharging device 100A has a shielding plate 131 that divides the interior of the housing 130 into a clamping section 110 and a power section 120, and is configured to allow ventilation. The shielding plate 131 may be configured as a grid structure to be horizontal with respect to the ground and to allow ventilation. With the shielding plate 131 as a reference, the clamping section 110 may be located above the shielding plate 131, and the power section 120 may be located below the shielding plate 131.

[0080] Compared with the charging and discharging device 100 of the above embodiment, the charging and discharging device 100A can provide cooling air to the clamp section 110 and the power section 120 respectively and remove heat, thereby improving the cooling efficiency of the charging and discharging device 100A compared with the above embodiment.

[0081] Specifically, refer to Figure 8 and Figure 9According to this embodiment, the ventilation hole 132 of the charging and discharging device 100A includes an upper first ventilation hole 132a and an upper second ventilation hole 133a located above the shielding plate 131. The upper first ventilation hole is disposed on the left side of the clamping section 110, and the upper second ventilation hole is disposed on the right side of the clamping section 110. Furthermore, the ventilation hole 132 also includes a lower first ventilation hole 132b and a lower second ventilation hole 133b located below the shielding plate 131. The lower first ventilation hole is disposed on the left side of the power section 120, and the lower second ventilation hole is disposed on the right side of the power section 120.

[0082] The upper first ventilation hole 132a and the lower first ventilation hole 132b can be configured to connect to the pipe module 200 located on the left side of the charging and discharging device 100A, and the upper second ventilation hole 133a and the lower second ventilation hole 133b can be configured to connect to the pipe module 200 located on the right side of the charging and discharging device 100A.

[0083] and Figure 4 Compared to the above embodiments, the pipe module 200 differs only in the number and position of the direct pipes, but there is no substantial structural difference. That is, the pipe module 200 can have multiple direct pipes and can be positioned between two charging and discharging device groups stacked vertically.

[0084] Furthermore, among the plurality of direct pipes, the direct pipe connected to the upper first vent 132a and lower first vent 132b of the charging and discharging device 100A located on the right side of the pipe module 200 can be used as a supply pipe for supplying cooling air, and the direct pipe connected to the upper second vent 133a and lower second vent 133b of the charging and discharging device 100A located on the left side of the pipe module 200 can be used as an exhaust pipe for removing heat. In this manner, the charging and discharging device groups 10A, 10B, 10C, 10D and the pipe module 200 according to another embodiment of this disclosure can be alternately arranged, such as... Figure 10 As shown.

[0085] According to this configuration, the clamping section 110 of each charging and discharging device 100A can receive cooling air through the pipe module 200 on the left side and the upper first vent 132a, and can remove heat through the upper second vent 133a and the pipe module 200 on the right side.
