[0037] In the following, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The terms and words used in this specification and claims should not be construed as limited to their ordinary or dictionary meanings, but rather should be interpreted as having meanings and concepts consistent with the technical spirit of the present disclosure, based on the inventor's ability to appropriately define the concepts of the terms to best describe the principles of their invention. The embodiments described in this specification and the configurations shown in the accompanying drawings are some embodiments of the present disclosure and do not represent all technical ideas, aspects, and features of the present disclosure. It should be understood that various equivalents and modifications may exist at the time of filing this application.

[0038] It will be understood that when a component or layer is referred to as being "on" another component or layer, "connected" to another component or layer, or "bonded" to another component or layer, it can be directly on, directly connected to, or directly bonded to the other component or layer, or there may be one or more intermediate components or layers. When a component or layer is referred to as being "directly on" another component or layer, "directly connected" to another component or layer, or "directly bonded" to another component or layer, there are no intermediate components or layers. For example, when a first component is described as being "bonded" or "connected" to a second component, the first component can be directly bonded or connected to the second component, or the first component can be indirectly bonded or connected to the second component via one or more intermediate components.

[0039] In the accompanying drawings, the dimensions of various elements, layers, etc., may be exaggerated for clarity. The same reference numerals denote the same elements. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. Furthermore, when describing embodiments of this disclosure, the use of "may" refers to "one or more embodiments of this disclosure." Expressions such as "at least one of..." and "any one of..." modify the entire list of elements when following a list, without modifying individual elements within that list. For example, the expression "at least one of a, b, or c" indicates only a, only b, only c, both a and b, both a and c, both b and c, all of a, b, and c, or variations thereof. As used herein, the terms "use," "using," and "being used" may be considered synonymous with the terms "utilize," "exploit," and "be utilized," respectively. A statement that two elements are "identical" to each other can mean that they are "substantially identical." Therefore, cases where elements are "substantially identical" can include cases with what are considered to be a low degree of deviation (e.g., about 5% or less). When a parameter is uniform in a region, it can mean that it is uniform in terms of the average value.

[0040] It will be understood that although the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers, and / or portions, these elements, components, regions, layers, and / or portions should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or portion from another element, component, region, layer, or portion. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or portion discussed below may be referred to as the second element, component, region, layer, or portion.

[0041] For ease of description, spatial relation terms such as “below,” “under,” “down,” “above,” “above,” etc., are used here to describe the relationship between one element or feature and another element or feature as shown in the figure. It will be understood that, in addition to the orientation depicted in the figure, spatial relation terms are intended to also cover other different orientations of the device in use or operation. For example, if the device in the figure is flipped, the element described as “below” or “under” other elements or features will be oriented as “above” or “above” other elements or features. Therefore, the term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatial relation descriptors used herein should be interpreted accordingly.

[0042] 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 “an” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that, when used in this specification, the terms “comprising,” “including,” “including,” and / or “containing” specify the presence of the stated features, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0043] In view of the entire contents of this disclosure, those skilled in the art will understand that each suitable feature of the various embodiments of this disclosure may be combined or integrated with each other in part or in whole, and may be technically interconnected and operated in a variety of suitable ways, and each embodiment may be implemented independently of each other or in any suitable way in combination with each other, unless otherwise stated or implied.

[0044] Furthermore, any numerical ranges disclosed and / or enumerated herein are intended to include all subranges containing the same numerical precision within the enumerated range. 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, that is, all subranges having 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 contained therein, and any minimum numerical limit enumerated in this specification is intended to include all higher numerical limits contained therein. Therefore, the applicant reserves the right to amend this specification (including the claims) to expressly enumerate any subranges included within the ranges expressly enumerated herein. All such ranges are deemed to be inherently described in this specification.

[0045] Figure 1 This is a perspective view of a battery module according to an embodiment of the present disclosure. Figure 2 yes Figure 1 The exploded perspective view of the battery module shown in the image. Figure 3 It is along Figure 1 A cross-sectional view taken from line I-I' in the diagram. Figure 4 It is shown Figure 1 An enlarged view of part A in the image.

[0046] In the following embodiments, the x-axis, y-axis, and z-axis are not limited to three axes in an orthogonal coordinate system, but can be interpreted in a broader sense that includes them. In some embodiments, the x-axis, y-axis, and z-axis may be orthogonal to each other, but may also refer to different directions that are not orthogonal to each other. In the following description, for ease of description, the x-axis is defined as the longitudinal (or length) direction of the protective circuit board portion 200, the y-axis is defined as the width direction of the protective circuit board portion 200, and the z-axis is defined as the thickness direction of the battery module 10.

[0047] Reference Figure 1 and Figure 2 According to embodiments of the present disclosure, the battery module 10 may include a frame 100, battery cells 300, and a protective circuit board portion 200 mounted on the frame 100. The battery module 10 may have a minimal stacked structure, and therefore can be formed into a thin shape.

[0048] According to embodiments of this disclosure, the battery module 10 may include a frame 100, a protective circuit board portion 200, and a battery cell 300.

[0049] Reference Figure 1 and Figure 2 The frame 100 may include a single-unit mounting portion 110 and a plate mounting portion 120.

[0050] The battery cell 300 can be mounted on the cell mounting portion 110. The cell mounting portion 110 can support the battery cell 300 on its surface that contacts the battery cell 300, thereby stably mounting the battery cell 300 on the cell mounting portion 110.

[0051] In some embodiments, the cell mounting portion 110 may be formed in a shape corresponding to the battery cell 300. For example, when the battery cell 300 is mounted on the cell mounting portion 110, the battery cell 300 may be supported by the cell mounting portion 110 in contact with the inner peripheral surface of the cell mounting portion 110.

[0052] Reference Figure 2 and Figure 3Support ribs 111 may be formed on the cell mounting portion 110 (e.g., along the periphery of the cell mounting portion 110). In the cell mounting portion 110, the support ribs 111 may be formed to protrude toward the interior of the cell mounting portion 110, such that when the battery cell 300 is mounted on the cell mounting portion 110, the support ribs 111 can support the battery cell 300 in the thickness direction (e.g., the z-axis direction) of the battery module 10.

[0053] In some embodiments, in the cell mounting portion 110, the support rib 111 may be formed to extend along the inner circumferential surface of the cell mounting portion 110 to have a width (e.g., a predetermined width). For example, the battery cell 300 may be mounted on the cell mounting portion 110 and supported on the entire inner circumferential surface of the cell mounting portion 110 (or supported along the entire inner circumferential surface of the cell mounting portion 110). Therefore, the battery cell 300 can be stably supported by the cell mounting portion 110.

[0054] Reference Figure 2 and Figure 3 The single-unit mounting portion 110 may include a fixing portion 112. The fixing portion 112 may be connected to the single-unit mounting portion 110 on one side and may be configured to be connected to an external component on the other side, thereby allowing the battery module 10 to be connected to an external component.

[0055] The fixing portion 112 can be attached to one side of the outer surface of the cell mounting portion 110. The fixing portion 112 can be formed on the surface of the cell mounting portion 110 opposite to the surface where the support rib 111 is formed, to connect the battery module 10 to the external component without interfering with the installation of the battery cell 300. This allows the battery module 10 to be securely connected to the mobile device.

[0056] In one embodiment, the fixing portion 112 may have a fixing hole (e.g., a fixing opening) 112a into which a bolt can be inserted. The bolt passing through the fixing hole 112a can be connected to an external component, such as a mobile device that includes the battery module 10 as a power source, thereby connecting the battery module 10 to the external component. Therefore, the fixing portion 112 can fix the relative position of the battery module 10 with respect to the external component.

[0057] The method of connecting the battery module 10 to an external component (such as a mobile device that includes the battery module 10 as a power source) using the fixing part 112 is not limited to the method described above. In some embodiments, the fixing part 112 and the external component can be connected to each other by welding.

[0058] The external component may be an electronic device that receives power from the battery module 10 (e.g., is powered by the battery module 10). In some embodiments, the external component may be a mobile device that uses the battery module 10 as a power source.

[0059] In some embodiments, the single-unit mounting portion 110 may include a plurality of fixing portions 112. In some embodiments, at least one fixing portion 112 is connected in each direction of the outer periphery of the single-unit mounting portion 110. Thus, the battery module 10 can be stably fixed to the external component without any wobbling (e.g., no vibration) in its relative position and orientation with respect to the external component.

[0060] Reference Figure 1 and Figure 2 The plate mounting portion 120 can be connected to one side of the single-unit mounting portion 110.

[0061] The board mounting portion 120 can be connected to a plurality of individual cell mounting portions 110. In some embodiments, the board mounting portion 120 can be arranged between a pair of individual cell mounting portions 110 facing each other and can be connected to each individual cell mounting portion 110. A pair of battery cells 300 arranged on a pair of individual cell mounting portions 110 can be connected to a protection circuit board 210 arranged on the board mounting portion 120, thereby enabling efficient power control.

[0062] Reference Figure 4 The plate mounting portion 120 may have a wing portion 120a and a connecting portion 120b.

[0063] The wing portion 120a can receive the electrode terminal 301 drawn from one side of the battery cell 300 (see example). Figure 2 In some embodiments, the wing portion 120a may be arranged between the protective circuit board portion 200 and the battery cell 300, and an electrode terminal 301 with a width extracted from the battery cell 300 may be arranged on the protective circuit board portion 200. Therefore, when connected to the protective circuit board 210, the electrode terminal 301 may be supported by the wing portion 120a.

[0064] The connecting portion 120b can connect a pair of wing portions 120a to each other. In some embodiments, the connecting portion 120b can connect the ends of the wing portions 120a to each other, thereby fixing the relative position of each wing portion 120a.

[0065] In some embodiments, the connecting portions 120b may be provided in pairs and may securely connect a pair of wing portions 120a. In some embodiments, a pair of connecting portions 120b may connect one end and the other end of one wing portion 120a to one end and the other end of another wing portion 120a, thereby improving the structural stability of the plate mounting portion 120.

[0066] Reference Figure 2 and Figure 4 The board mounting portion 120 can accommodate the protective circuit board portion 200. In some embodiments, the board mounting portion 120 can form a space surrounded (e.g., around its periphery) by a pair of wing portions 120a and a pair of connecting portions 120b, thereby accommodating the protective circuit board 210 therein.

[0067] Figure 5 yes Figure 2 A magnified view of part B in the image. Figure 6 yes Figure 4 A magnified view of part C in the image. Figure 7 yes Figure 4 A magnified view of part D in the image. Figure 8 It is along Figure 1 The cross-sectional view taken from line II-II' in the diagram. Figure 9 It is along Figure 1 The cross-sectional view taken from line III-III' in the diagram.

[0068] Reference Figure 1 , Figure 2 and Figure 4 The protective circuit board portion 200 can be mounted on the board mounting portion 120. In some embodiments, the protective circuit board portion 200 can be mounted on the board mounting portion 120 by being inserted into the interior of the board mounting portion 120 and supported by each component of the board mounting portion 120.

[0069] Reference Figure 2 The board mounting portion 120 can accommodate the protective circuit board portion 200, wherein the opposite surface of the protective circuit board portion 200 is mounted as open (e.g., exposed).

[0070] The board mounting portion 120 can support the protective circuit board portion 200 housed therein. For example, a contact support portion 121 can be formed on the board mounting portion 120 to protrude inward, such that the protective circuit board portion 200 can be contact-supported in the thickness direction (e.g., the z-axis direction) of the battery module 10. Therefore, the protective circuit board portion 200 can be mounted on the board mounting portion 120.

[0071] Reference Figure 2 , Figure 6 and Figure 8The contact support portion 121 can be arranged inside the mating groove 211 formed in the protective circuit board 210 of the protective circuit board portion 200, and can contact the cover tab 220 covering the mating groove 211.

[0072] The contact support portion 121 may be disposed inside the mating groove 211 formed in the protective circuit board portion 200. In some embodiments, the contact support portion 121 may be formed in a shape corresponding to the mating groove 211 and may be disposed inside the mating groove 211.

[0073] The contact support portion 121 can be disposed inside the mating groove 211 to contact the cover tab 220. The contact support portion 121 can support the protective circuit board 210 in the thickness direction (e.g., z-axis direction) of the battery module 10 by supporting the cover tab 220 connected to the protective circuit board 210 in the thickness direction of the battery module 10. For example, the contact support portion 121 can be disposed inside the mating groove 211 to contact and support the protective circuit board portion 200.

[0074] The top end of the contact support portion 121 can contact the bottom end of the cover tab 220 covering the mating groove 211. For example, the top end of the contact support portion 121 can be arranged at substantially the same height as the top end of the protective circuit board 210. As a result, the contact support portion 121 and the protective circuit board 210 can be arranged at the same position as each other in the thickness direction of the battery module 10, and the contact support portion 121 and the cover tab 220 can be arranged to spatially overlap in the thickness direction of the battery module 10.

[0075] Reference Figure 8 The contact support portion 121 can support the protective circuit board portion 200 within the mating groove 211 via the cover tab 220, thereby reducing the height at which the protective circuit board portion 200 is arranged to reduce the thickness of the protective circuit board 210. For example, the height difference d between the bottom portion of the protective circuit board portion 200 and the bottom portion of the connecting portion 120b can be substantially 0, or can be within a range (e.g., a preset or predetermined range).

[0076] Reference Figure 1 and Figure 2 Multiple contact support portions 121 can be formed on the board mounting portion 120. The protective circuit board portion 200 can be stably mounted on the board mounting portion 120 by being supported by the multiple contact support portions 121. As the load applied to each contact support portion 121 decreases (e.g., as the load is distributed across more contact support portions 121), the structural stability of the battery module 10 can be improved.

[0077] In one embodiment, a pair of contact support portions 121 may be formed within the board mounting portion 120 to protrude toward each other. In some embodiments, the pair of contact support portions 121 may be formed to protrude inward from each connection portion 120b to face each other. Thus, the protective circuit board portion 200 can be supported at both ends in its longitudinal direction, and therefore can be stably mounted on the board mounting portion 120.

[0078] Reference Figure 1 , Figure 4 and Figure 9 The board mounting portion 120 can support and protect the circuit board portion 200 and the battery cell 300 by including the partition portion 122.

[0079] Reference Figure 1 , Figure 2 and Figure 5 The partition portion 122 can be mounted on the wing portion 120a of the board mounting portion 120. The partition portion 122 can be connected to the wing portion 120a having a width (e.g., a predetermined width) and can be stably mounted on the wing portion 120a. Therefore, the circuit board portion 200 and the battery cell 300 can be more stably supported by the partition portion 122.

[0080] The board mounting portion 120 may include a partition portion 122 to support the protective circuit board portion 200 and the battery cell 300 in the width direction (e.g., the y-axis direction) of the protective circuit board portion 200. In some embodiments, the partition portion 122 of the board mounting portion 120 may be arranged between the protective circuit board portion 200 and the battery cell 300 such that one surface of the partition portion 122 can contact the protective circuit board portion 200 and another surface of the partition portion 122 opposite to said one surface can contact the battery cell 300, thereby contacting and supporting the protective circuit board portion 200 and the battery cell 300.

[0081] Reference Figure 4 and Figure 5 The partition portion 122 may have a partition 122a and a reinforcing rib 122b.

[0082] The separator 122a may have a length (e.g., a predetermined length) and may be provided in a shape that extends along the thickness direction (e.g., the z-axis direction) of the battery module 10. For example, the separator 122a may be formed as a plate having an area (e.g., a preset or predetermined area).

[0083] The separator 122a may have a surface that contacts the protective circuit board portion 200 and another surface that contacts the battery cell 300. For example, the separator 122a may support the protective circuit board portion 200 and the battery cell 300 in a direction perpendicular to the surface of the separator (e.g., in the y-axis direction). Therefore, the protective circuit board portion 200 and the battery cell 300 may be stably mounted on the board mounting portion 120 and the cell mounting portion 110, respectively, without wobbling (e.g., without vibration).

[0084] The reinforcing rib 122b can support the partition 122a. In some embodiments, the reinforcing rib 122b can support the partition 122a by connecting the partition 122a to the wing portion 120a.

[0085] The reinforcing rib 122b may have a thickness sufficient to support the partition 122a. For example, the partition 122a may be connected to the reinforcing rib 122b having a thickness, thereby contacting the reinforcing rib 122b over a wider area.

[0086] The reinforcing rib 122b can be bent and connected to one end portion and the other end portion of the partition 122a. One end portion and the other end portion (e.g., opposite ends) of the reinforcing rib 122b can be connected to each end portion of the partition 122a, and the reinforcing rib 122b can be bent to increase the contact area between the reinforcing rib 122b and the wing portion 120a. Therefore, the reinforcing rib 122b can firmly support the partition 122a.

[0087] The board mounting portion 120 may include a plurality of partition portions 122. In some embodiments, the board mounting portion 120 may have a plurality of partition portions 122 arranged in the longitudinal direction of the wing portion 120a. Since the loads applied from the battery cell 300 and the protective circuit board portion 200 are separated and applied (e.g., distributed) to the plurality of partition portions 122, the structural stability of the board mounting portion 120 can be improved.

[0088] The plurality of partitions 122 arranged on the wing portion 120a can be arranged to be spaced apart from each other at a regular (or preset) interval. For example, adjacent partitions 122 on the wing portion 120a can be arranged to be spaced apart from each other at a regular interval, so that space can be provided in the interval for arranging electrode terminals 301. Therefore, electrode terminals 301 can be mounted on the single mounting portion 110, and thus can be stably connected to the protection circuit board 210.

[0089] Reference Figure 4 , Figure 5 , Figure 9The press support portion 122c may be formed in the partition portion 122. In some embodiments, the press support portion 122c may be formed on one side of the partition 122a of the partition portion 122 to protrude toward the interior of the plate mounting portion 120.

[0090] The press-support portion 122c can support the protective circuit board portion 200. In some embodiments, the press-support portion 122c can be formed to protrude from one side of the separator 122a and can contact the top portion of the protective circuit board portion 200. For example, the press-support portion 122c can contact the top portion of the protective circuit board portion 200 and can support the protective circuit board portion 200 in a direction opposite to the direction in which the contact support portion 121 supports the protective circuit board portion 200 (e.g., the -z axis direction).

[0091] The pressing support portion 122c can contact the protective circuit board portion 200 supported by the contact support portion 121. For example, the pressing support portion 122c can contact the protective circuit board portion 200 supported by the contact support portion 121 in the thickness direction (e.g., the z-axis direction) of the battery module 10 in a direction opposite to the height direction (e.g., the z-axis direction). Therefore, the protective circuit board portion 200 can be mounted on the board mounting portion 120 without wobbling.

[0092] The surface of the pressing support portion 122c that contacts the protective circuit board portion 200 can be parallel to the protective circuit board portion 200. Because the surfaces of the pressing support portion 122c and the protective circuit board portion 200 that contact each other are arranged parallel to each other, the contact area between the pressing support portion 122c and the protective circuit board portion 200 can be increased or maximized. Therefore, the pressure applied to the protective circuit board portion 200 by the pressing support portion 122c can be reduced, thereby maintaining the durability of the protective circuit board portion 200.

[0093] Multiple press-support portions 122c may be formed in the partition portion 122. In some embodiments, the multiple press-support portions 122c may be formed to protrude from one partition portion 122, or one press-support portion 122c may be formed in each partition portion 122 (or formed to protrude from each partition portion 122). Therefore, as the load applied to each of the press-support portions 122c and the protective circuit board portion 200 decreases, the durability of the battery module 10 can be improved.

[0094] Reference Figure 4 , Figure 7 and Figure 9The retaining support portion 122d may be formed in the partition portion 122. In some embodiments, the retaining support portion 122d may be formed on one side of the partition 122a of the partition portion 122, so as to protrude toward the interior of the plate mounting portion 120.

[0095] The retaining support portion 122d can support the protective circuit board portion 200. In some embodiments, the retaining support portion 122d can be formed to protrude from one side of the separator 122a toward the interior of the board mounting portion 120, and can be disposed inside the retaining groove 212 formed in the protective circuit board portion 200. The retaining support portion 122d can be disposed inside the retaining groove 212 such that when the protective circuit board portion 200 moves in a direction parallel to the wing portion, the retaining support portion 122d can support the protective circuit board portion 200 by contacting the supporting retaining groove 212.

[0096] The retaining support portion 122d can have a cylindrical shape. For example, the protection circuit board 210 can move in the thickness direction (e.g., the z-axis direction) of the battery module 10 while the retaining support portion 122d is arranged inside the retaining groove 212. Therefore, the protection circuit board 210 can be easily mounted on the board mounting portion 120.

[0097] Multiple retaining support portions 122d may be formed on the partition portion 122. In some embodiments, the multiple retaining support portions 122d may be formed to protrude from one partition portion 122, or a single retaining support portion 122d may be formed in each partition portion 122. Therefore, as the load applied to each of the retaining support portions 122d and the protective circuit board portion 200 decreases, the durability of the battery module 10 can be improved.

[0098] exist Figure 2 , Figure 4 , Figure 5 The illustration shows an embodiment where a pressing support portion 122c or a holding support portion 122d is formed on a partition portion 122, but this disclosure is not limited thereto. In some embodiments, at least one pressing support portion 122c and at least one holding support portion 122d may be formed on a single partition portion 122.

[0099] Reference Figure 1 , Figure 2 and Figure 4 The protection circuit board portion 200 can be mounted on the board mounting portion 120 and electrically connected to the battery cell 300. The protection circuit board portion 200 can control the voltage and current of the connected battery cell 300 to regulate the output of the battery module 10 and ensure stability during operation.

[0100] In one embodiment, the protective circuit board portion 200 may include a protective circuit board 210 and a cover tab 220.

[0101] The protection circuit board 210 can be electrically connected to the battery cell 300. In some embodiments, the protection circuit board 210 can be connected to the electrode terminal 301 that is pulled out from one side of the battery cell 300 to receive electrical energy from the battery cell 300 and / or control the electrical energy output from the battery cell 300.

[0102] The electrode terminals 301 of the protection circuit board 210 and the battery cell 300 can be connected to each other, for example, by laser welding, but this disclosure is not limited thereto.

[0103] Protection circuitry for controlling the voltage and current of the battery cells 300 can be formed on the protection circuit board 210. In some embodiments, the protection circuitry can be printed on the protection circuit board 210 to monitor and control the voltage and current of the electrically connected battery cells 300. This can prevent overvoltage or overcurrent of the battery module 10.

[0104] Reference Figure 1 , Figure 2 and Figure 4 The protection circuit board 210 can be mounted on the board mounting portion 120. In some embodiments, the protection circuit board 210 can be accommodated in the space defined by the connecting portion 120b and the wing portion 120a, and thus can be supported by each component of the board mounting portion 120.

[0105] The protection circuit board 210 can be supported by the contact support portion 121. The protection circuit board 210 can be supported in the thickness direction (e.g., z-axis direction) of the battery module 10 by the contact support portion 121 protruding toward the interior of the board mounting portion 120.

[0106] Reference Figure 2 , Figure 6 and Figure 8 The protective circuit board 210 can be supported by the contact support portion 121 through the cover tab 220.

[0107] In some embodiments, the protective circuit board 210 may have a mating groove 211 formed on one side, such that the contact support portion 121 can be disposed inside the mating groove 211, and the cover tab 220 covering the mating groove 211 can simultaneously contact the contact support portion 121 and the protective circuit board 210, so that the protective circuit board 210 is contact-supported by the contact support portion 121.

[0108] A mating groove 211 may be formed in the protective circuit board 210, wherein the contact support portion 121 is disposed inside the mating groove 211. In some embodiments, a mating groove 211 having a shape corresponding to the contact support portion 121 may be formed on one side of the protective circuit board 210, such that when the contact support portion 121 is disposed inside the mating groove 211, the inner peripheral surface of the mating groove 211 can be supported to contact the contact support portion 121.

[0109] Multiple mating grooves 211 may be formed in the protective circuit board 210. In some embodiments, a pair of mating grooves 211 may be formed on one side and the other side of the protective circuit board 210. The pair of mating grooves 211 may be covered by a pair of cover tabs 220, which are supported by a pair of contact support portions 121 formed on the board mounting portion 120. For example, the protective circuit board 210 may be stably mounted on the board mounting portion 120 by being supported on opposite sides of the board mounting portion 120.

[0110] The top portion of the protective circuit board 210 can be positioned at substantially the same height as the top portion of the contact support portion 121. For example, the top of the contact support portion 121 can contact the bottom end of the cover tab 220 covering the mating groove 211, such that the contact support portion 121 and the protective circuit board 210 can be positioned at the same location relative to each other in the thickness direction (e.g., the z-axis direction) of the battery module 10. As a result, the contact support portion 121 and the protective circuit board 210 can be positioned at the same location (or at the same level) relative to each other in the thickness direction (e.g., the z-axis direction) of the battery module 10, and can be arranged to spatially overlap in the thickness direction (e.g., the z-axis direction) of the battery module 10.

[0111] Reference Figure 8 The protective circuit board 210 can be supported by the contact support portion 121 via the cover tab 220 covering the mating groove 211, so that the height at which the protective circuit board 210 is arranged can reduce the thickness of the protective circuit board 210. Therefore, the height difference d between the bottom portion of the protective circuit board 210 and the bottom portion of the connecting portion 120b can be substantially 0, or can be within a range (e.g., a preset or predetermined range).

[0112] The protective circuit board 210 can be supported by the partition portion 122. The protective circuit board 210 can be supported by the partition portion 122 in a direction perpendicular to the surface of the partition 122a (e.g., the y-axis direction), or in a direction opposite to the direction supported by the contact support portion 121 (e.g., the -z-axis direction), or in a direction parallel to the wing portion 120a (e.g., the x-axis direction).

[0113] Reference Figure 9The protective circuit board 210 can be supported by the separator 122a. In some embodiments, the protective circuit board 210 can be supported in a direction perpendicular to the surface of the separator 122a (e.g., the y-axis direction) by contacting the surface of the separator 122a.

[0114] Reference Figure 4 and Figure 9 The protective circuit board 210 can be supported by a press-support portion 122c, which is formed to protrude from the partition 122a. In some embodiments, the top portion of the protective circuit board 210 can contact the press-support portion 122c protruding from one side of the partition 122a.

[0115] For example, the protective circuit board 210 can be supported by the pressing support portion 122c in a direction opposite to the direction in which the protective circuit board 210 is supported by the contact support portion 121 (e.g., the -z axis direction). Therefore, the protective circuit board 210 can be mounted on the board mounting portion 120 without excessive wobbling.

[0116] Reference Figure 8 and Figure 9 The protective circuit board 210 can contact the contact support portion 121 and simultaneously contact the pressing support portion 122c. In some embodiments, the protective circuit board 210 can be supported by the contact support portion 121 in the thickness direction (e.g., the z-axis direction) of the battery module 10, while it can be supported by the pressing support portion 122c in the opposite direction (e.g., the -z-axis direction) to the direction in which the protective circuit board 210 is supported by the contact support portion 121. Therefore, the protective circuit board 210 can be stably mounted on the board mounting portion 120 without wobbling in the height direction.

[0117] Reference Figure 4 and Figure 7 The protective circuit board 210 can be supported by a retaining support portion 122d that protrudes from the partition 122a. In some embodiments, the protective circuit board 210 can be supported by the retaining support portion 122d when the retaining support portion 122d protruding from one side of the partition 122a is arranged inside the retaining groove 212.

[0118] A retaining groove 212 can be formed in the protective circuit board 210, and a retaining support portion 122d is disposed inside the retaining groove 212. In some embodiments, the retaining groove 212 can be formed with a shape corresponding to the retaining support portion 122d. Therefore, when the retaining support portion 122d is disposed inside the retaining groove 212, the inner peripheral surface of the retaining groove 212 can contact the retaining support portion 122d, so that the protective circuit board 210 can be supported by the retaining support portion 122d without wobbling.

[0119] Reference Figure 2 and Figures 6 to 8 The cover tab 220 can cover the mating groove 211. The cover tab 220 can cover the top portion of the mating groove 211 and can contact the contact support portion 121 disposed inside the mating groove 211.

[0120] The cover tab 220 can be connected to the protective circuit board 210 while covering the mating groove 211. Therefore, the cover tab 220 can transfer the supporting force applied from the contact support portion 121 to the protective circuit board 210.

[0121] In some embodiments, the cover tab 220 can be attached to the protective circuit board 210 by methods such as laser welding, but this disclosure is not limited thereto.

[0122] The tab 220 may be contacted and supported by the contact support portion 121. In some embodiments, the tab 220 may cover the engagement groove 211 and may contact the top portion of the contact support portion 121 inserted into the engagement groove 211.

[0123] Reference Figure 6 and Figure 8 The bottom portion of the cover tab 220 can simultaneously contact the top portion of the contact support portion 121 and the top portion of the protective circuit board 210.

[0124] Therefore, the cover tab 220 can transmit the supporting force applied from the contact support portion 121 to the protective circuit board 210, while keeping the contact support portion 121 and the protective circuit board 210 arranged at the same height.

[0125] The protective circuit board portion 200 may include a plurality of cover tabs 220. In some embodiments, when a pair of mating grooves 211 are formed in one side and the other side of the protective circuit board 210, the protective circuit board portion 200 may include a pair of cover tabs 220 to cover each of the pair of mating grooves 211 respectively.

[0126] Each tab 220 can cover the mating groove 211, so that the opposite side of the protective circuit board portion 200 can be supported by the contact support portion 121. Therefore, the protective circuit board portion 200 can be stably mounted on the board mounting portion 120.

[0127] Reference Figure 1 and Figure 2 The battery cell 300 can store electrical energy and transmit it to the outside, and can be installed on the cell mounting part 110 so that the voltage and current of the battery cell 300 can be controlled by the protection circuit board part 200.

[0128] The battery cell 300 can be formed in the shape of a plate. The battery cell 300 can be, for example, a pouch-shaped cell, but this disclosure is not limited thereto. Therefore, the thickness of the battery module 10 can be thin.

[0129] The battery cell 300 can be mounted on the cell mounting portion 110. In some embodiments, the battery cell 300 can be contacted and supported by the cell mounting portion 110 and can be stably mounted on the cell mounting portion 110.

[0130] Reference Figure 2 The battery cell 300 can be supported by the cell mounting portion 110. In some embodiments, the cell mounting portion 110 can be formed in a shape corresponding to the battery cell 300, and its inner peripheral surface can support the battery cell 300 mounted on the cell mounting portion 110.

[0131] The battery cell 300 can be supported by a support rib 111 formed on the cell mounting portion 110. In some embodiments, the battery cell 300 can be supported in the thickness direction (e.g., the z-axis direction) of the battery module 10 by the support rib 111 extending a width along the inner peripheral surface of the cell mounting portion 110. Therefore, the battery cell 300 can be stably mounted by the cell mounting portion 110.

[0132] Reference Figure 1 , Figure 4 and Figure 5 The battery cell 300 may be supported by the partition portion 122. In some embodiments, the battery cell 300 may be supported by a partition 122a disposed between the protective circuit board 210 and the partition portion 122.

[0133] The electrode terminal 301 can be pulled out from one side of the battery cell 300. In some embodiments, the electrode terminal 301 connected to the electrode assembly housed inside the battery cell 300 can be pulled out from one side of the battery cell 300.

[0134] Battery cell 300 can be electrically connected to other components. In some embodiments, battery cell 300 can be electrically connected to another component via electrode terminals 301, which extend from the electrode assembly of battery cell 300 and extend out from one side of battery cell 300. In some embodiments, electrode terminals 301 of battery cell 300 can be electrically connected to protection circuit board 210 to electrically connect protection circuit board 210 to the electrode assembly. For example, battery cell 300 can be electrically connected to protection circuit board 210 via electrode terminals 301.

[0135] Electrode terminals 301 may be arranged between partition portions 122 mounted adjacent to each other on the wing portion 120a. In some embodiments, electrode terminals 301 may be connected to the protection circuit board 210 by providing space between the partition portions 122 mounted adjacent to each other. Therefore, the electrical connection between electrode terminals 301 and protection circuit board 210 can be stably maintained.

[0136] The configuration, operating principle, and effects of the battery module 10 and the mobile device including it according to embodiments of the present disclosure will be described below.

[0137] Reference Figure 1 and Figure 2 According to embodiments of the present disclosure, the battery module 10 may include a frame 100, a protective circuit board portion 200, and a battery cell 300.

[0138] The frame 100 can provide space in which the battery cell 300 and the protective circuit board portion 200 can be installed. The frame 100 may include components that support each of the battery cell 300 and the protective circuit board portion 200 to stably install the battery cell 300 and the protective circuit board portion 200.

[0139] Reference Figure 2 The frame 100 may include a single-unit mounting portion 110 and a plate mounting portion 120.

[0140] The cell mounting portion 110 can support the battery cell 300 mounted thereon. In some embodiments, the cell mounting portion 110 can be formed in a shape corresponding to the battery cell 300, such that its inner peripheral surface can contact and support the battery cell 300.

[0141] The single-cell mounting portion 110 may include a support rib 111, which is formed to extend along the inner peripheral surface of the single-cell mounting portion 110 and has a width sufficient to support the mounted battery cell 300 in the thickness direction (e.g., the z-axis direction) of the battery module 10.

[0142] Therefore, the battery cell 300 can be stably installed through the cell mounting part 110.

[0143] The individual mounting portion 110 may include a retaining portion 112 attached to its outer peripheral surface. The retaining portion 112 may connect the battery module 10 to an external component. In some embodiments, a retaining hole 112a may be formed in the retaining portion 112, such that the battery module 10 and the external component can be connected to each other by bolts passing through the retaining hole 112a and the external component.

[0144] Reference Figure 1 , Figure 4 and Figures 6 to 9The board mounting portion 120 can support the protective circuit board portion 200 mounted thereon. Each component provided in the board mounting portion 120 can form a layout relationship that keeps the thickness of the battery module 10 thin while stably supporting the protective circuit board portion 200.

[0145] The board mounting portion 120 may form a space therein for accommodating the protective circuit board portion 200. In some embodiments, the board mounting portion 120 may include a pair of wing portions 120a and a connecting portion 120b connecting the end portions of the respective wing portions 120a, thereby forming a space therein for arranging the protective circuit board portion 200.

[0146] The board mounting portion 120 can support the protective circuit board 210 in the thickness direction (e.g., the z-axis direction) of the battery module 10. In some embodiments, the board mounting portion 120 may have an inwardly formed contact support portion 121 to support the protective circuit board portion 200.

[0147] In some embodiments, the contact support portion 121 may be disposed inside the mating groove 211 formed in the protective circuit board 210, and may support the cover tab 220 covering the mating groove 211. Therefore, the thickness of the battery module 10 formed by mounting the protective circuit board 210 on the board mounting portion 120 can be reduced.

[0148] The board mounting portion 120 can support the protection circuit board 210, so that the protection circuit board 210 can be installed stably without shaking.

[0149] Reference Figure 2 and Figure 9 The board mounting portion 120 can support and protect the circuit board portion 200 through the partition portion 122 mounted on the wing portion 120a.

[0150] Reference Figure 9 The separator 122a of the separator 122 can support the protective circuit board portion 200 in a direction perpendicular to the surface of the separator 122a (e.g., the y-axis direction). In some embodiments, the separator 122a can be arranged between the protective circuit board portion 200 and the battery cell 300 to support the protective circuit board portion 200 without it wobbling.

[0151] The partition 122 may include a reinforcing rib 122b that supports the partition 122a. For example, the partition 122a may be supported by the reinforcing rib 122b, which is connected to the partition 122a on one side and to the wing portion 120a on the other side, so that the protective circuit board portion 200 and the battery cell 300 can be stably supported.

[0152] Reference Figure 5 and Figure 9 The press-support portion 122c may be formed to protrude from the partition 122a toward the interior of the board mounting portion 120 to support the protective circuit board portion 200. In some embodiments, the press-support portion 122c may contact the top portion of the protective circuit board portion 200 and support the protective circuit board portion 200 in a direction opposite to the direction in which the contact support portion 121 contacts and supports the protective circuit board portion 200.

[0153] In some embodiments, the pressing support portion 122c can contact the protective circuit board portion 200 that contacts the contact support portion 121, so that the protective circuit board portion 200 can be stably mounted on the board mounting portion 120 without wobbling in the thickness direction (e.g., the z-axis direction) of the battery module 10.

[0154] Reference Figure 7 and Figure 9 The retaining support portion 122d may be formed to protrude from the partition 122a toward the interior of the board mounting portion 120 to support the protective circuit board portion 200. In some embodiments, the retaining support portion 122d may be arranged inside the retaining groove 212 formed in the protective circuit board portion 200 to support the protective circuit board portion 200 in a direction parallel to the wing portion 120a (e.g., the x-axis direction).

[0155] Reference Figure 1 The protection circuit board portion 200 can be mounted on the board mounting portion 120 and can be electrically connected to the battery cell 300 to control the voltage and current of the battery cell 300.

[0156] In one embodiment, the protective circuit board portion 200 may include a protective circuit board 210 and a cover tab 220.

[0157] The protective circuit board 210 can be mounted on the board mounting portion 120 and can be supported by each component of the board mounting portion 120. In some embodiments, the protective circuit board 210 can be supported by the contact support portion 121 of the board mounting portion 120, and can be supported by the spacer 122a, the press support portion 122c, and the retaining support portion 122d of the partition portion 122.

[0158] Reference Figure 6 and Figure 8 The protective circuit board 210 can be mounted on the board mounting portion 120 while maintaining the thinness of the battery module 10. In some embodiments, a mating groove 211 can be formed in the protective circuit board 210, wherein a contact support portion 121 is arranged inside the mating groove 211 such that the contact support portion 121 can support the cover tab 220 covering the mating groove 211.

[0159] The tab 220 may cover the mating groove 211 formed in the protective circuit board 210. In some embodiments, the tab 220 may cover the mating groove 211 and may be supported by a contact support portion 121 disposed inside the mating groove 211.

[0160] The tab 220 can transmit the supporting force applied from the contact support portion 121 to the connected protective circuit board 210, thereby allowing the protective circuit board 210 to be supported by the contact support portion 121.

[0161] The cover tab 220 can simultaneously contact the top portion of the contact support portion 121 and the top portion of the protective circuit board 210. For example, the top portion of the contact support portion 121 and the top portion of the protective circuit board 210 can be arranged at the same height as each other by the cover tab 220.

[0162] The battery cell 300 can be mounted on the cell mounting portion 110 and supported by the inner peripheral surface of the cell mounting portion 110 and the support rib 111 formed along the inner peripheral surface of the cell mounting portion 110.

[0163] Electrode terminals 301, which are drawn out from one side of the battery cell 300, can be connected to an electrode assembly housed inside the battery cell 300 to electrically connect external components to the electrode assembly.

[0164] The electrode terminal 301 can be connected to the protection circuit board portion 200 by providing space between adjacent partition portions 122, so that the voltage and current of the battery cell 300 can be controlled by the protection circuit board 210.

[0165] The mobile device may include a battery module 10 to receive power from the battery module 10. In some embodiments, the mobile device may be electrically connected to a protection circuit board portion 200 of the battery module 10 to receive electrical energy stored in the battery cells 300. The mobile device may receive electrical energy with voltage and current controlled within a range (e.g., a preset or predetermined range) by the protection circuit board 210 of the protection circuit board portion 200.

[0166] The mobile device including the battery module 10 may be, for example, a mobile phone, a tablet computer, or a laptop computer, but this disclosure is not limited thereto.

[0167] In the battery module and mobile device including the battery module according to embodiments of the present disclosure, the battery cells and protection circuit board can be mounted on a frame to maintain the slim shape of the battery module.

[0168] However, the aspects and features of this disclosure are not limited to those described above, and those skilled in the art will clearly understand other aspects and features not mentioned from the description of this disclosure above.

[0169] The spirit of this disclosure should not be determined by limiting it to the above-described embodiments, and not only by the claims, but also by any scope that falls within the scope of this disclosure and is equivalent to or equivalent to the claims.

[0170] Although this disclosure has been described herein with reference to some embodiments and accompanying drawings, this disclosure is not limited thereto, and various modifications and changes can be made by those skilled in the art within the technical spirit and equivalent scope of the claims.
