[0045] Exemplary embodiments will now be described more fully below with reference to the accompanying drawings; however, they may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey exemplary implementations to those skilled in the art.

[0046] In the drawings, the dimensions of layers and areas may be exaggerated for clarity. It will also be understood that when a layer or element is referred to as "on" another layer or element, it can be directly on that other layer or element, or there may be intervening layers. Furthermore, it will be understood that when a layer is referred to as "below" another layer, it can be directly below that other layer, or there may be one or more intervening layers. Additionally, it will be understood that when a layer is referred to as "between two layers," it can be the only layer between those two layers, or there may be one or more intervening layers. The same reference numerals refer to the same elements throughout.

[0047] The terms or words used in this specification and claims should not be construed as limited to their ordinary or dictionary meanings, and should be interpreted as meanings and concepts consistent with the technical ideas of this disclosure, based on the principle that the inventor is his / her own lexicographer in order to properly define the concepts of the terms.

[0048] The terms or words used in this specification and claims should not be construed as limited to their ordinary or dictionary meanings, and should be interpreted as having meanings and concepts consistent with the technical ideas of this disclosure, based on the principle that the inventor himself can be a lexicographer to properly define the concepts of the terms.

[0049] It is important to understand that when an element or layer is referred to as being "on" another element or layer, "connected to," or "linked to" another element or layer, it can be directly on, directly connected to, or linked to that other element or layer, or there may be one or more intermediary elements or layers. When an element or layer is referred to as being "directly on" another element or layer, "directly connected to," or "directly linked to" another element or layer, there are no intermediary elements or layers. For example, when a first element is described as being "linked" or "connected" to a second element, the first element can be directly linked or connected to the second element, or the first element can be indirectly linked or connected to the second element via one or more intermediary elements.

[0050] As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. Furthermore, the use of “may” in describing embodiments of this disclosure refers to “one or more embodiments of this disclosure.” When expressions such as “at least one of…” and “any one of…” follow a list of elements, they modify the entire list of elements, not individual elements within the list. When a list of elements A, B, and C is indicated by terms such as “at least one of A, B, and C,” “at least one selected from the group of A, B, and C,” or “at least one selected from A, B, and C,” the term may refer to any and all suitable combinations or suitable subsets of A, B, and C, such as A, B, C, A and B, A and C, B and C, or A and B and C. As used herein, the term “use” and variations thereof may be considered synonymous with the term “utilize” and variations thereof, respectively. As used herein, the terms “substantially,” “about,” and similar terms are used as approximations rather than terms of degree, and are intended to explain the inherent variations in measured or calculated values ​​that will be recognized by one of ordinary skill in the art.

[0051] It should be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, areas, layers, and / or portions, these elements, components, areas, layers, and / or portions should not be limited by these terms. These terms are used to distinguish one element, component, area, layer, or portion from another element, component, area, layer, or portion. Therefore, the first element, component, area, layer, or portion discussed below may be referred to as a second element, component, area, layer, or portion without departing from the teachings of the exemplary embodiments.

[0052] For ease of description, spatial relative terms such as “below,” “under,” “down,” “above,” and “above” are used herein to describe the relationship between one element or feature and another element(s) illustrated in the figures. It is to be understood that these spatial relative terms are intended to cover different orientations of the device in use or operation, in addition to those described in the figures. For example, if the device in the figures is flipped, the element described as “below” or “under” other elements will then be oriented “above” or “above” that other element or feature. Thus, the term “below” can encompass both above and below orientations. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relative descriptors used herein should be interpreted accordingly.

[0053] The terminology used herein is for the purpose of describing embodiments of this disclosure and is not intended to limit the disclosure. As used herein, the singular forms “a” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It is to be further understood that, when used in this specification, the term “comprising” and variations thereof indicate the presence of the described features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof.

[0054] Furthermore, any numerical ranges disclosed and / or enumerated herein are intended to include all subranges with the same numerical precision that are incorporated within the enumerated ranges. For example, the range “1.0 to 10.0” is intended to include all subranges between (and including) the enumerated minimum value of 1.0 and the enumerated maximum value of 10.0, i.e., all subranges with a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0, such as, for example, 2.4 to 7.6. Any maximum numerical limit enumerated herein is intended to include all lower numerical limits incorporated therein, and any minimum numerical limit enumerated herein is intended to include all higher numerical limits incorporated therein. Accordingly, the applicant reserves the right to amend this specification (including the claims) to expressly enumerate any subranges incorporated within the range expressly enumerated herein.

[0055] Referring to two compared elements, features, etc., as “identical” can mean that they are “substantially identical.” Therefore, the term “substantially identical” can include cases where there is a deviation considered low in the art (e.g., 5% or less). Furthermore, when a parameter is said to be uniform in a given region, this can mean that it is uniform in terms of average value.

[0056] Throughout the instruction manual, unless otherwise stated, each element may be singular or plural.

[0057] When any element is described as being set (or placed or positioned) "above (or below)" or "on top (or below)" a component, this can mean that the element is placed in contact with the upper (or lower) surface of the component, and it can also mean that another component can be inserted between the component and any element set (or placed or positioned) on (or below) the component.

[0058] Furthermore, it should be understood that when an element is referred to as being “connected,” “linked,” or “attached” to another element, these elements may be directly “connected,” “linked,” or “attached” to each other, or one or more intermediary elements may exist between them (through which the element may be “connected,” “linked,” or “attached” to the other element). Additionally, when a part is referred to as being “electrically connected” to another part, the part may be directly electrically connected to the other part, or one or more intermediary parts may exist between them, such that the part and the other part are indirectly electrically connected to each other.

[0059] Throughout the instruction manual, unless otherwise stated, when “A and / or B” is used, it means A, B, or A and B. That is, “and / or” includes any or all combinations of the listed items. Unless otherwise stated, when “C to D” is used, it means C and below D.

According to this embodiment, the housing cover 12 can be formed as a flat plate (the flat plate is positioned to face the upper surface of the housing body 11). The housing cover 12 can be attached to the housing body 11 using any of a variety of connection methods, such as welding and bolting.

[0066] The battery cell 2 can serve as a unit structure in the battery module for storing and supplying power.

[0067] The management module 3 can detect the status and / or operation information of the battery cell 2, and transmit the status and / or operation information of the battery cell 2 by communicating with the battery management system (BMS).

Figure 2 A schematic cross-sectional view of the configuration of a single battery cell.

[0070] refer to Figure 2 and Figure 3 The battery cell 2 may include: one or more electrode assemblies 24, wherein a positive electrode 241, a negative electrode 242 and a separator 243 (which is an insulator and disposed between the positive electrode 241 and the negative electrode 242) are wound around the electrode assemblies 241; a housing 20 in which the electrode assemblies 24 are mounted; and a cover assembly 21 connected to an opening of the housing 20.

[0071] In the following description, a prismatic lithium-ion secondary battery will be used as an example of battery cell 2. However, battery cell 2 can be a lithium polymer battery or a cylindrical battery.

[0072] The electrode assembly 24 may have a roll in which a positive electrode 241, a negative electrode 242, and a diaphragm 243 (which is an insulator and inserted between the positive electrode 241 and the negative electrode 242) are wound. However, the electrode assembly 24 may also be formed as a stacked structure in which a positive electrode 241 and a negative electrode 242 formed of a plurality of sheets are stacked together and a diaphragm 243 is inserted therebetween.

[0073] The positive electrode 241 and the negative electrode 242 may include coated portions (areas of the metal foil coated with active material) and uncoated portions (areas of the metal foil not coated with active material) (e.g., the uncoated portion 2411 of the positive electrode and the uncoated portion 2421 of the negative electrode).

[0074] The housing 20 can form the overall appearance of the battery cell 2 and provide space therein to accommodate the electrode assembly 24. According to this embodiment, the housing 20 can have a hollow rectangular hexahedral shape with an open side. The housing 20 can be formed of a conductive metal such as aluminum, aluminum alloy, or nickel-coated steel.

Positive terminals 221 and negative terminals 222, which are electrically connected to positive electrode 241 and negative electrode 242, may be mounted to pass through the cover plate 210 and protrude outward.

[0077] The upper outer peripheral surfaces of the positive terminal 221 and the negative terminal 222, which protrude outward from the cover plate 210, can be threaded and secured to the cover plate 210 with nuts. However, the positive terminal 221 and the negative terminal 222 can be formed with a riveted structure and riveted or welded to the cover plate 210.

[0078] An electrolyte injection hole 211 can be formed in the cover plate 210, and a sealing plug can be installed in the electrolyte injection hole 211.

[0081] For example, the positive terminal 221 and the negative terminal 222 can be welded to the first current collector 251 and the second current collector 252, respectively. However, the positive terminal 221 and the negative terminal 222 can be formed to be integrally connected to the first current collector 251 and the second current collector 252.

[0082] An insulating member can be installed between the electrode assembly 24 and the cover plate 210. In this case, the insulating member may include a first insulating member 261 and a second insulating member 262, and each of the first insulating member 261 and the second insulating member 262 may be installed between the electrode assembly 24 and the cover plate 210.

[0083] According to this embodiment, one end of the separation member, which is mounted to face one side surface of the electrode assembly 24, can be installed between the insulating member and the positive terminal 221. In this case, the separation member may include a first separation member 271 and a second separation member 272.

[0088] Figure 4 This is a plan view illustrating a management module disposed in a battery module according to one or more embodiments of the present disclosure, and Figure 5 This is a partial plan view illustrating a management module according to one or more embodiments of the present disclosure. Figure 6 This is a partial perspective view illustrating a management module according to one or more embodiments of the present disclosure, and Figure 7 This is a partially exploded top perspective view showing a management module according to one or more embodiments of the present disclosure. Figure 8 This is a partially exploded bottom perspective view illustrating a management module according to one or more embodiments of the present disclosure.

[0089] Figures 4 to 8 The battery cell 2 and the management module 3 shown in the figure are Figures 1 to 3 The battery cell 2 shown in the diagram is the same as the management module 3. Accordingly, the description of the same components can be omitted.

[0090] The configuration of management module 3 will be briefly described below.

[0091] The management module 3 may include a sensing module 31 and a communication module 32.

[0092] The sensing module 31 can be in contact with or electrically connected to the positive terminal 221 and / or negative terminal 222 of the battery cell 2, and can detect the operating information of the battery cell 2. The sensing module 31 can detect the operating information of the battery cell 2, such as voltage, current, and temperature. The sensing module 31 can detect the operating information of multiple battery cells 2.

[0093] The operational information of the battery cell 2 detected by the sensing module 31 can be transmitted to the communication module 32, which is electrically connected to the sensing module 31. According to one or more embodiments, the sensing module 31 and the communication module 32 can be connected by wiring, so that the operational information of the battery cell 2 can be transmitted to the communication module 32.

[0094] The communication module 32 can transmit the operation information of the battery cell 2 received from the sensing module 31 to the BMS. According to one or more embodiments, the communication module 32 can wirelessly transmit the operation information of the battery cell 2 to the BMS.

[0095] The management module 3 may further include a busbar retainer 33.

[0096] A busbar holder 33 may be disposed on the battery cell 2 and support the sensing module 31 and the communication module 32. According to one or more embodiments, the busbar holder 33 may be disposed on the battery cell 2. The busbar holder 33 may support a busbar electrically connected to the positive terminal 221 and / or the negative terminal 222 of the battery cell 2 (e.g., Figure 4 Busbar 3300). Since busbar 3300 is supported by busbar retainer 33, the movement of busbar can be restricted, and even when battery module 1 is subjected to external impact, busbar 3300 can be prevented from separating from positive terminal 221 and / or negative terminal 222.

[0097] The detailed configuration of management module 3 will be described below.

[0098] The sensing module 31 may include a sensing module body 310, a sensing element 311, and a sensing pad portion 312.

[0099] The sensing module body 310 can be provided as a flexible printed circuit board (FPCB). As described above, since the sensing module body 310 is provided as an FPCB, the shape of the sensing module body 310 can be changed relatively freely.

[0100] The sensing module 31 can be fixedly mounted on the busbar holder 33. For example, the sensing module 31 can be disposed on the busbar holder 33. According to one or more embodiments, the sensing module body 310 can be disposed on the busbar holder 33. The sensing module body 310 can be disposed on the busbar holder 33 and connected to the battery cell 2.

[0101] The sensing module 31 may include a sensing module body hole 3100, providing a hole for passing through the sensing module body 310 (in Figure 7(Best shown in the diagram). A plurality of sensing module body holes 3100 can be provided. A busbar retainer 33 can be inserted into the sensing module body holes 3100. According to one or more embodiments, a protruding busbar retainer portion 331 and / or a protruding busbar retainer pin 3311 of the busbar retainer 33 can be inserted into the sensing module body holes 3100. Accordingly, the sensing module body 310 can be secured to the busbar retainer 33.

[0102] The sensing element 311 can extend from the sensing module body 310. The sensing element 311 can be provided as an FPCB. The sensing element 311 can extend from the sensing module body 310 and contact or be connected to the busbar 3300 of the battery cell 2 and / or busbar holder 33. Multiple sensing elements 311 can be provided. Accordingly, operational or status information of the battery cell 2 and / or busbar 3300 can be detected by the sensing element 311.

[0103] When the sensing element 311 comes into contact with or is connected to the battery cell 2 and / or the busbar 3300, the sensing module 31 can detect the operation information of the battery cell 2. According to one or more embodiments, the sensing element 311 can detect the temperature, current, voltage, etc., of the battery cell 2. The operation information of the battery cell 2 detected by the sensing element 311 can be transmitted through the sensing line 3122 in the sensing module body 310 (see...). Figure 9 The signal is transmitted to the sensing pad portion 312. The sensing line 3122 can be disposed in the sensing module body 310.

[0104] The sensing pad portion 312 can be connected to the sensing line 3122. Multiple sensing lines 3122 connected to multiple sensors 311 can be connected to the sensing pad portion 312. The sensing pad portion 312 can be disposed on the sensing module body 310 and in contact with the communication module 32. The sensing pad portion 312 can be disposed on the sensing module body 310 and electrically connected to the sensing element 311.

[0105] According to one or more embodiments, the sensing pad portion 312 may contact the communication pad portion 321 of the communication module 32. When the sensing pad portion 312 and the communication pad portion 321 are in contact with each other and electrically connected, the operation information and / or status information of the battery cell 2 and / or busbar 3300 detected by the sensing element 311 can be transmitted to the communication module 32 through the sensing pad portion 312 and the communication pad portion 321.

[0106] Due to the sensing pad portion 312 and the communication pad portion 321 (see...) Figure 5 as well as Figure 9The sensing module bodies 310 are provided as contacts to each other, rather than as connectors, thus eliminating the need for a specific shape to accommodate connector movement. As described above, since a shape is not required for connector movement, the sensing module bodies 310 do not need to be cut, and since the sensing module bodies 310 are not cut, no waste is generated, minimizing material waste. Furthermore, since a shape is not required for connector connection, the sensing module bodies 310 do not need to be cut, the sensing lines 3122 do not need to be clustered, and no bottleneck phenomenon occurs.

[0107] The communication module 32 may include a communication module body 320, a communication pad portion 321, communication module components 322, and a communication module body hole 323 (see...). Figure 7 ).

[0108] The communication module body 320 can be provided as a printed circuit board (PCB), or it can be provided as an unprinted circuit board (FPCB). The communication module body 320 can be disposed on the sensing module 31. According to one or more embodiments, the communication module body 320 can be disposed on the sensing module body 310. As described above, since the communication module body 320 is disposed on the sensing module body 310, the busbar holder 33, the sensing module body 310, and the communication module body 320 can be stacked sequentially.

[0109] The communication pad portion 321, the communication module component 322, and the communication module body hole 323 can be disposed on the communication module body 320.

[0110] The communication pad portion 321 may be disposed on the communication module body 320 and contact the sensing pad portion 312 on the sensing module body 310. According to one or more embodiments, the communication pad portion 321 may be located on the lower part of the communication module body 320.

[0111] When the communication pad portion 321 contacts and is electrically connected to the sensing pad portion 312, the communication module 32 can receive signals from the sensing module 31. The signals transmitted from the sensing module 31 to the communication module 32 may include operation information and / or status information of the battery cell 2 and / or busbar holder 33.

[0112] The communication module element 322 can be disposed on the communication module body 320. The communication module element 322 can be electrically connected to the communication pad portion 321, receive signals transmitted from the sensing pad portion 312, and transmit signals to or receive signals from components outside the management module 3.

[0113] According to one or more embodiments, the management module 3 can communicate wirelessly with the BMS. When the management module 3 communicates wirelessly with the BMS, the operation information and / or status information of the battery cell 2 and / or busbar 3300 can be transmitted to the BMS.

[0114] The communication module 32 may include a communication module body hole 323, provided as a hole through which the communication module body 320 passes. Multiple communication module body holes 323 may be provided. According to one or more embodiments, a protruding busbar retainer pin 3311 of the busbar retainer 33 can be inserted into the communication module body hole 323. When the busbar retainer 33 is inserted into the communication module body hole 323, the communication module body 320 can be secured to the busbar retainer 33.

[0115] The busbar holder 33 may include a busbar holder body 330 and a busbar holder portion 331 protruding from the busbar holder body 330. The busbar holder 33 may further include a busbar 3300. The busbar holder 33 may further include a busbar holder fastener 332. The protruding busbar holder portion 331 of the busbar holder 33 can be inserted into the communication module body hole 323.

[0116] The busbar holder 33 can be disposed between the battery cell 2 and the sensing module 31. The busbar holder body 330 can be placed on the battery cell 2, and the busbar 3300, the protruding busbar holder portion 331 and the busbar holder fastener 332 can be disposed on the busbar holder body 330.

[0117] Busbar 3300 can connect the electrodes of battery cell 2. According to one or more embodiments, busbar 3300 can be connected to the positive terminal 221 and / or negative terminal 222 of battery cell 2. Accordingly, multiple battery cells 2 can be connected in series and / or in parallel. When multiple battery cells 2 are connected in series and / or in parallel, the voltage may increase or the limit on the flow current may increase. Accordingly, the capacity of battery module 1 can be increased.

[0118] The protruding busbar retainer portion 331 can be configured to protrude from the busbar retainer body 330. According to one or more embodiments, the protruding busbar retainer portion 331 can protrude upwards (e.g., in the +Z axis direction) from the busbar retainer body 330. The protruding busbar retainer portion 331 can protrude upwards from the busbar retainer body 330 and can be coupled to the busbar retainer fastener 332.

[0119] A protruding busbar retainer pin 3311 may be configured to protrude from the busbar retainer body 330. According to one or more embodiments, the protruding busbar retainer pin 3311 may protrude upwards (e.g., in the +Z axis direction) from the busbar retainer body 330. The protruding busbar retainer pin 3311 may be configured to pass through the sensing module body hole 3100 of the sensing module 31 and / or the communication module body hole 323 of the communication module 32. The protruding busbar retainer pin 3311 passing through the sensing module body hole 3100 and / or the communication module body hole 323 may be secured to the busbar retainer fixing member 332. The busbar retainer fixing member 332 may include a busbar retainer fixing body and a busbar retainer fixing groove 3321, which is recessed and located within the busbar retainer fixing body. According to one or more embodiments, the protruding busbar retainer pin 3311 can be inserted into the busbar retainer fixing groove 3321 of the busbar retainer fixing member 332. When the protruding busbar retainer pin 3311 is inserted into the busbar retainer fixing groove 3321, it can prevent the sensing module 31 and / or the communication module 32 from separating from the busbar retainer 33.

[0120] Busbar retainer 332 may be disposed on sensing module 31 and / or communication module 32 (e.g., in the +Z axis direction). According to one or more embodiments, busbar retainer 332 may be disposed on communication module 32 and coupled to protruding busbar retainer portion 331.

[0121] The management module 3 may further include an inflow prevention member 34 between the communication module 32 and the sensing module 31. (See also: Inflow prevention member 34) Figure 7 The inflow prevention member 34 can be disposed on the sensing module body 310. The inflow prevention member 34 can be disposed between the sensing module 31 and the communication module 32. According to one or more embodiments, the inflow prevention member 34 can be disposed on the sensing module body 310 to surround the sensing pad portion 312 and the communication pad portion 321. Since the inflow prevention member 34 is disposed to surround the sensing pad portion 312 and the communication pad portion 321, it is possible to prevent foreign matter such as moisture from being introduced into the sensing pad portion 312 and the communication pad portion 321.

[0122] exist Figure 7 The figure shows an inflow prevention member 34 configured around the sensing pad portion 312 and the communication pad portion 321, but examples of the inflow prevention member 34 are not limited thereto. The inflow prevention member 34 may be provided for each terminal in contact with the sensing pad portion 312 and the communication pad portion 321 (e.g., Figure 9 The recessed sensing pad portion 3121 or the protruding communication pad portion 3211, or Figure 15 The protruding sensing pad portion 3124 or the recessed communication pad portion 3216) surrounds a single terminal.

[0123] As described above, the sensing module 31 and / or the communication module 32 can be disposed on the busbar holder 33 and secured to the busbar holder 33 by the protruding busbar holder portion 331 and / or the busbar holder fastener 332. For example, the busbar holder fastener 332 can press the communication module 32 toward the sensing module 31.

[0124] Figure 9 This is a cross-sectional view illustrating a state in which a sensing module and a communication module are in contact according to one or more embodiments of the present disclosure, and Figure 10 This is a cross-sectional view illustrating a state in which the sensing module and the communication module are spaced apart according to one or more embodiments of the present disclosure. Figure 11 This is a cross-sectional view illustrating a state in which the sensing module and the communication module are spaced apart according to another embodiment of the present disclosure, and Figures 12 to 14 Each is a plan view illustrating the layout of the sensing pad portion of a sensing module and the communication pad portion of a communication module according to one or more embodiments of the present disclosure.

[0125] Figures 9 to 14 The sensing module 31, sensing module body 310, sensing pad portion 312, sensing line 3122, communication module 32, communication module body 320, and communication pad portion 321 shown in the figure are... Figures 1 to 8 The sensing module 31, sensing module body 310, sensing pad portion 312, sensing line 3122, communication module 32, communication module body 320, and communication pad portion 321 shown in the figure are identical. Accordingly, descriptions of identical components can be omitted.

[0126] refer to Figure 9 and Figure 10 As can be seen, the sensing pad portion 312 of the sensing module 31 and the communication pad portion 321 of the communication module 32.

[0127] Since the sensing pad portion 312 and the communication pad portion 321 are not implemented as connectors, and the sensing module 31 and the communication module 32 are configured to overlap each other, the sensing pad portion 312 and the communication pad portion 321 can contact each other and be electrically connected.

[0128] As described above, since the sensing pad portion 312 and the communication pad portion 321 overlap and are electrically connected, no additional connector structure is required. Because no connector structure is needed, the space required to connect the sensing module 31 and the communication module 32 can be reduced, and the circuit integration density can be lowered, thereby preventing bottlenecks and reducing the complexity of circuit design.

[0129] Furthermore, since the sensing module 31 provided as an FPCB does not require a connector structure, there is no need to cut the sensing module 31 for connection with a connector. Accordingly, the manufacturing process of the sensing module 31 can be simplified, the manufacturing time of the sensing component 31 can be reduced, and the cost of the sensing component 31 can be reduced.

[0130] When connector structures are implemented on sensing module 31 and / or communication module 32, workers must exercise close care when removing or attaching the connectors, and there is a high possibility of damaging sensing module 31 and / or communication module 32. Since connector structures are not required, communication module 32 can be easily attached to or removed from sensing module 31. Furthermore, the process of separating communication module 32 from sensing module 31 is greatly simplified, and the difficulty of the separation process is reduced.

[0131] refer to Figure 9 and Figure 10 The sensing line 3122 can be disposed in the sensing module body 310 of the sensing module 31. According to one or more embodiments, the sensing line 3122 can be disposed in the sensing module body 310. The sensing line 3122 can be connected to the sensing element 311 and transmit the information detected by the sensing element 311 to the sensing pad portion 312.

[0132] The sensing line 3122 can be connected to the sensing pad portion 312.

[0133] The sensing pad portion 312 may include a recessed sensing pad portion 3121 recessed in the sensing module body 310. The recessed sensing pad portion 3121 may be provided as a groove recessed downward (e.g., in the -Z-axis direction) from the upper side (e.g., in the +Z-axis direction) of the sensing module body 310.

[0134] A sensing plate 3123 may be disposed on a recessed sensing pad portion 3121. According to one or more embodiments, the sensing plate 3123 may be disposed on and electrically connected to the sensing line 3122 (e.g., in the +Z axis direction) and transmit electrical signals to the sensing line 3122. The sensing plate 3123 may contact the communication module 32. According to one or more embodiments, the sensing plate 3123 may contact and be electrically connected to the communication pad portion 321 of the communication module 32. The sensing plate 3123 may comprise a highly conductive material such as gold, silver, or copper. Since the sensing line 3122 and the communication module 32 are connected through the sensing plate 3123, rather than directly on it, the sensing plate 3123 can protect the sensing line 3122.

[0135] The communication pad portion 321 may be disposed in the recessed sensing pad portion 3121. According to one or more embodiments, the communication pad portion 321 may be inserted into the recessed sensing pad portion 3121.

[0136] Communication line 3212 may be disposed in the communication module body 320. According to one or more embodiments, communication line 3212 may be disposed in the communication module body 320. Communication line 3212 may be connected to communication pad portion 321 and may transmit electrical signals to communication pad portion 321. According to one or more embodiments, signals transmitted from sensing pad portion 312 to communication pad portion 321 can be transmitted via communication line 3212 to communication module element 322 of communication module 32 (see...). Figure 7 ).

[0137] The communication pad portion 321 may include a protruding communication pad portion 3211 that protrudes from the communication module body 320. The protruding communication pad portion 3211 may protrude downward (e.g., in the -Z-axis direction) from the upper side (e.g., in the +Z-axis direction) of the communication module body 320.

[0138] The protruding communication pad portion 3211 can be placed within the recessed sensing pad portion 3121. For example, the protruding communication pad portion 3211 can be inserted into and contact the recessed sensing pad portion 3121. When the protruding communication pad portion 3211 is inserted into and contacts the recessed sensing pad portion 3121, the protruding communication pad portion 3211 and the recessed sensing pad portion 3121 can be electrically connected to each other. Accordingly, the sensing module 31 and the communication module 32 can be electrically connected.

[0139] The protruding communication pad portion 3211 can be electrically connected to the communication line 3212, and the communication solder 3213 can be disposed below the communication line 3212 (e.g., in the -Z axis direction).

[0140] The communication solder 3213 can be solder that is set during the manufacturing process. The communication solder 3213 can electrically connect the communication line 3212 and the communication pad 3214, and fix the communication pad 3214.

[0141] Communication pad 3214 may be disposed below communication solder 3213 (e.g., in the -Z axis direction) and electrically connected to communication solder 3213. Communication pad 3214 may be electrically connected to sensing line 3122. Communication pad 3214 may be formed of a highly conductive conductor.

[0142] The communication board 3215 can be disposed below the communication pad 3214 (e.g., in the -Z axis direction) and is electrically connected to the communication pad 3214. Since the communication pad 3214 is connected to the sensing module 31 via the communication board 3215, rather than directly connected to it, the communication board 3215 can protect the communication pad 3214. The communication board 3215 can be formed of highly conductive conductors such as gold, silver, and copper.

[0143] refer to Figure 11 It can be seen that the shape of the recessed sensing pad portion 3121 and the shape of the protruding communication pad portion 3211 are different from each other.

[0144] The cross-sectional area of ​​the recessed sensing pad portion 3121 and the protruding communication pad portion 3211 can increase along one direction. According to one or more embodiments, the cross-sectional area of ​​the recessed sensing pad portion 3121 perpendicular to the Z-axis direction can increase along the +Z-axis direction.

[0145] An inclined portion intersecting the Z-axis direction may be provided on a portion of the sensing module body 310 and a portion of the cross-section of the sensing plate 3123 of the recessed sensing pad portion 3121. A communication board 3215 may contact and be electrically connected to the sensing plate 3123. According to one or more embodiments, the cross-sectional shape of a portion of the sensing module body 310 and a portion of the sensing plate 3123 of the recessed sensing pad portion 3121 may be set to a generally trapezoidal shape.

[0146] An inclined portion intersecting the Z-axis direction may be formed on a portion of the communication module body 320 and a portion of the cross-section of the communication pad 3214 of the protruding communication pad portion 3211 and the communication board 3215. According to one or more embodiments, the cross-sectional shape of the communication pad 3214 of the protruding communication pad portion 3211 and a portion of the communication board 3215 may be set to a generally trapezoidal shape.

[0147] As described above, since the cross-sectional shape is provided as a roughly trapezoidal shape, the contact between the sensing pad portion 312 and the communication pad portion 321 can be guided when the communication module 32 contacts the sensing module 31.

[0148] refer to Figures 9 to 11 The cross-sectional area of ​​the recessed sensing pad portion 3121 can be formed to be larger than the cross-sectional area of ​​the protruding communication pad portion 3211. According to one or more embodiments, the area obtained by cutting the recessed sensing pad portion 3121 in a direction perpendicular to the Z-axis can be formed to be larger than the area of ​​the protruding communication pad portion 3211.

[0149] As described above, because the cross-sectional area of ​​the recessed sensing pad portion 3121 is formed to be larger than the cross-sectional area of ​​the protruding communication pad portion 3211, the sensing module 31 and the communication module 32 can be electrically connected even when the communication module 32 is not positioned at the precise location desired by the designer. (Refer to...) Figures 12 to 14 To describe its example.

[0150] refer to Figure 12 As can be seen, the sensing module 31 and / or the communication module 32 are precisely positioned at the designed location, such that the protruding communication pad portion 3211 is positioned at the center of the recessed sensing pad portion 3121 of the sensing module 31. Correspondingly, it can be seen that the communication board 3215 of the protruding communication pad portion 3211 is positioned at the center of the sensing board 3123 of the recessed sensing pad portion 3121.

[0151] refer to Figure 13 As can be seen, the sensing module 31 and / or the communication module 32 are configured to be offset in one direction (e.g., the -X-axis direction) rather than precisely positioned at the designed location, such that the protruding communication pad portion 3211 is disposed in the end of one side (e.g., in the -X-axis direction) of the recessed sensing pad portion 3121. Accordingly, it can be seen that the communication board 3215 of the protruding communication pad portion 3211 is disposed in the end of one side (e.g., in the -X-axis direction) of the sensing board 3123 of the recessed sensing pad portion 3121.

[0152] refer to Figure 14As can be seen, the sensing module 31 and / or the communication module 32 are configured to be offset in one direction (e.g., in the -Y-axis direction) rather than precisely positioned at the designed location, such that the protruding communication pad portion 3211 is disposed in the end of one side (e.g., in the -Y-axis direction) of the recessed sensing pad portion 3121. Accordingly, it can be seen that the communication board 3215 of the protruding communication pad portion 3211 is disposed in the end of one side (e.g., in the -Y-axis direction) of the sensing board 3123 of the recessed sensing pad portion 3121.

[0153] like Figures 12 to 14 As such, since the cross-sectional area of ​​the recessed sensing pad portion 3121 is formed to be larger than the cross-sectional area of ​​the protruding communication pad portion 3211, the sensing module 31 and / or the communication module 32 can be electrically connected even when they are not precisely positioned at their designed locations. Consequently, the required precision for assembling the management module 3 can be reduced, and manufacturing (assembly) time can be decreased.

[0154] According to embodiments of this disclosure, the height of the protruding communication pad portion 3211 may be greater than the depth of the recessed sensing pad portion 3121.

[0155] Figure 15 This is a cross-sectional view illustrating a state in which the sensing module and the communication module are spaced apart according to another embodiment of the present disclosure, and Figure 16 The figure shows a plan view illustrating the arrangement relationship between the sensing pad portion of the sensing module and the communication pad portion of the communication module according to another embodiment of the present disclosure.

[0156] Figure 15 and 16 The implementation shown in the figure is similar to Figure 10 and 11 The implementation method is illustrated in the figure. Figure 15 and Figure 16 The middle figure shows an embodiment in which the sensing pad portion 312 protrudes from the sensing module body 310 and the communication pad portion 321 is recessed in the communication module body 320.

[0157] The sensing pad portion 312 may include a protruding sensing pad portion 3124, and the communication pad portion 321 may include a recessed communication pad portion 3216.

[0158] The protruding sensing pad portion 3124 can be inserted into and contact the recessed communication pad portion 3216. When the protruding sensing pad portion 3124 and the recessed communication pad portion 3216 are in contact with each other, the sensing module 31 and the communication module 32 can be electrically connected.

[0159] The protruding sensing pad portion 3124 may include protruding sensing solder 3124-1, protruding sensing pad 3124-2, and protruding sensing plate 3124-3.

[0160] The protruding sensing pad portion 3124 may be disposed in the communication pad portion 321 (e.g., disposed in the recessed communication pad portion 3216). According to one or more embodiments, the protruding sensing pad portion 3124 may be inserted into the communication pad portion 321.

[0161] Sensing line 3122 may be disposed in sensing module body 310. According to one or more embodiments, sensing line 3122 may be disposed in sensing module body 310. Sensing line 3122 may be connected to sensing pad portion 312 and transmit electrical signals to sensing pad portion 312.

[0162] The sensing pad portion 312 may include a protruding sensing pad portion 3124 formed to protrude from the sensing module body 310. The protruding sensing pad portion 3124 may protrude upward (e.g., in the +Z axis direction) from the lower side (e.g., in the -Z axis direction) of the sensing module body 310.

[0163] The protruding sensing pad portion 3124 can be inserted into and contact the recessed communication pad portion 3216. When the protruding sensing pad portion 3124 is inserted into and contacts the recessed communication pad portion 3216, the protruding sensing pad portion 3124 and the recessed communication pad portion 3216 can be electrically connected. Accordingly, the sensing module 31 and the communication module 32 can be electrically connected.

[0164] The protruding sensing pad portion 3124 can be connected to the sensing line 3122, and the protruding sensing solder 3124-1 can be disposed on the sensing line 2122 (e.g., in the +Z axis direction).

[0165] The protruding sensing solder 3124-1 can be solder and can be set during the manufacturing process. The protruding sensing solder 3124-1 can electrically connect the sensing line 3122 and the protruding sensing pad 3124-2, and fix the protruding sensing pad 3124-2.

[0166] A protruding sensing pad 3124-2 may be disposed on the protruding sensing solder 3124-1 (e.g., in the +Z axis direction) and electrically connected to the protruding sensing solder 3124-1. The protruding sensing pad 3124-2 may be electrically connected to the communication line 3212. The protruding sensing pad 3124-2 may be formed of a highly conductive conductor.

[0167] A protruding sensing plate 3124-3 may be disposed on the protruding sensing pad 3124-2 (e.g., in the +Z axis direction) and electrically connected to the protruding sensing pad 3124-2. Since the protruding sensing pad 3124-2 is connected to the communication module 32 via the protruding sensing plate 3124-3, rather than being directly connected to it, the protruding sensing plate 3124-3 can protect the protruding sensing pad 3124-2. The protruding sensing plate 3124-3 may be formed of a highly conductive conductor such as gold, silver, or copper.

[0168] The recessed communication pad portion 3216 may include a recessed communication board 3216-1.

[0169] A recessed communication board 3216-1 may be disposed within a recessed communication pad portion 3216. According to one or more embodiments, the recessed communication board 3216-1 may be disposed below (e.g., in the -Z-axis direction) and electrically connected to the communication line 3212, and may transmit electrical signals to the communication line 3212. The recessed communication board 3216-1 may contact the sensing module 31. According to one or more embodiments, the recessed communication board 3216-1 may contact and be electrically connected to the sensing pad portion 312 of the sensing module 31. The recessed communication board 3216-1 may comprise a highly conductive material such as gold, silver, or copper. Since the communication line 3212 is connected to the sensing module 31 via the recessed communication board 3216-1, rather than directly connected to it, the recessed communication board 3216-1 can protect the communication line 3212.

[0170] The area of ​​the recessed communication pad portion 3216 can be formed to be larger than the area of ​​the protruding sensing pad portion 3124. According to one or more embodiments, the area obtained by cutting the recessed communication pad portion 3216 in a direction perpendicular to the Z-axis can be formed to be larger than the area of ​​the protruding sensing pad portion 3124.

[0171] As described above, since the area of ​​the recessed communication pad portion 3216 is formed to be larger than the area of ​​the protruding sensing pad portion 3124, the sensing module 31 and / or the communication module 32 can be electrically connected even when they are not precisely positioned at their designed locations. Consequently, the required precision for assembling the management module 3 can be reduced, and manufacturing (assembly) time can be decreased.

[0172] refer to Figure 16 You can see and reference Figures 12 to 14 The advantages described in this disclosure correspond to the advantages.

[0173] Figure 17 This is a cross-sectional view illustrating a state in which the sensing module and the communication module are spaced apart according to another embodiment of the present disclosure.

[0174] Figure 17 The implementation shown in the figure is similar to Figure 10 and 11 The implementation method is illustrated in the figure. Figure 17 The middle figure shows an embodiment in which the contact guide 350 is positioned adjacent to the sensing pad portion 312 and the communication pad portion 321.

[0175] refer to Figure 17 The contact guide 350 can be disposed on the sensing module body 310 and the communication module body 320, and can guide the contact between the sensing pad portion 312 and the communication pad portion 321.

[0176] The contact guide 350 may include a guide member 351 and an adhesive member 352.

[0177] An attractive force can function between the two guide members 351. According to one or more embodiments, the guide member 351 can be provided as a magnet. The shape of the guide member 351 can be provided as any of a variety of shapes, such as a hexahedral shape and a wheel-like (ring-like) shape.

[0178] Multiple guide members 351 may be disposed on the sensing module body 310 and / or the communication module body 320 (e.g., on each of the sensing pad portion 312 and the communication pad portion 321), and attractive forces may act between them. When attractive forces act between the guide members 351, the sensing module 31 and the communication module 32 may be arranged to contact each other as desired by the designer when the sensing module 31 and the communication module 32 come into contact due to the attractive forces between the multiple guide members 351.

[0179] Furthermore, since the attraction between the multiple guide members 351 will take effect even after the sensing module 31 and the communication module 32 have come into contact with each other, the sensing module 32 and the communication module 31 can be fixed.

[0180] Adhesive component 352 may be disposed on sensing module body 310 and / or communication module body 320, and may fix guide component 351.

[0184] Figures 18 to 20 The diagram shows a sensing module 31, a sensing module body 310, a sensing element 311, a communication module 32, a communication module body 320, a busbar holder body 330, a busbar 3300, a protruding busbar holder portion 331, and a busbar holder fixing member 332. Figures 1 to 16 The sensing module 31, sensing module body 310, sensing element 311, communication module 32, communication module body 320, busbar holder body 330, busbar 3300, protruding busbar holder portion 331, and busbar holder fixing member 332 shown in the figure are identical. Accordingly, descriptions of identical components can be omitted.

[0185] refer to Figures 18 to 20 As can be seen, the sensing module body 310 and the communication module body 320 are fixed by the protruding busbar holder portion 331 and the busbar holder fastener 332.

[0186] The protruding busbar retainer portion 331 may include a protruding busbar retainer pin 3311 and / or a protruding busbar retainer protrusion 3312. Furthermore, the busbar retainer fastener 332 may include a busbar retainer retaining groove 3321 and / or a busbar retainer retaining protrusion 3322.

[0187] The protruding busbar retainer pin 3311 and the protruding busbar retainer protrusion 3312 can be configured to protrude from the busbar retainer body 330, for example, upward (e.g., in the +Z axis direction).

[0188] The protruding busbar retainer pin 3311 can pass through the elastic member 333, the sensing module body hole 3100 of the sensing module body 310, and the communication module body hole 323 of the communication module body 320, and can be inserted into the busbar retainer fixing member 332. According to one or more embodiments, the protruding busbar retainer pin 3311 can be inserted into the busbar retainer fixing groove 3321 formed in a recessed shape in the busbar retainer fixing member 332.

[0189] The protruding busbar retainer protrusion 3312 can be connected to the busbar retainer fixing member 332. According to one or more embodiments, the protruding busbar retainer protrusion 3312 can be connected to the busbar retainer fixing protrusion 3322 provided on the busbar retainer fixing member 332, and when the protruding busbar retainer protrusion 3312 is connected to the busbar retainer fixing protrusion 3322, the busbar retainer fixing member 332 can be prevented from separating from the busbar retainer body 330.

[0190] The busbar retainer 33 may further include an elastic member 333. The elastic member 333 may be disposed between the sensing module body 310 and the protruding busbar retainer portion 331 and / or between the communication module body 320 and the busbar retainer fixing member 332. The elastic member 333 may be formed of an elastic material such as rubber.

[0191] Because the elastic member 333 is disposed between the sensing module body 310 and the protruding busbar holder portion 331 and / or between the communication module body 320 and the busbar holder fastener 332, damage to the sensing module body 310 and / or the communication module body 320 can be prevented. Furthermore, when the elastic member 333 presses the sensing module body 310 and the communication module body 320 together, bringing them closer, the contact between the sensing pad portion 312 on the sensing module body 310 and the communication pad portion 321 on the communication module body 320 can be maintained.

[0192] Secondary batteries are widely used not only for powering or storing energy in small devices such as portable electronic devices, but also for powering and storing energy in medium and large devices such as electric vehicles or energy storage systems (ESS). In particular, in the case of medium and large devices, multiple battery cells are electrically connected to form a battery module in order to increase the battery's output power and capacity.

[0193] This battery module includes a sensing module for measuring the temperature and voltage of individual battery cells to detect potential explosion risks due to overheating and perform protective actions, and a communication module for transmitting the information measured by the sensing module. When communication between the sensing module and the communication module is performed via wiring, a method is needed for easily removing and attaching the communication module and the sensing module to maintain the connection of the communication module.

[0194] In the management module according to this disclosure and the battery module including the management module, the communication module and the sensing module can be easily removed and attached.

[0195] Furthermore, in the management module according to this disclosure and the battery module including the management module, it is possible to prevent damage to the sensing module and the communication module during the separation process.

[0196] Furthermore, the contact between the sensing module and the communication module can be improved in the management module according to this disclosure and the battery module including the management module.
