Description

Technical Field

[0001] The present disclosure relates to the technical field of battery packs, and in particular to battery packs and vehicles. Background Art

[0002] A battery pack typically includes a shell, battery cells installed in the shell, and an electrical module (such as a control module, etc.) installed in the shell. The electrical module is spaced apart on one side of the battery cell, and the electrical module is provided with a connector for electrically connecting to the battery cell. In the related art, during the production of the battery pack, it is necessary to pour glue into the shell so that the battery cells and other components are fixedly connected to the shell, thereby improving the stability of the internal components of the battery pack and the overall strength of the battery pack. During the glue pouring process, the positions of the shell corresponding to the battery cells need to be filled with glue, while the glue at the electrical module position needs to be lower than the connector to avoid damaging the connector. However, since the shell is a connected space, there will be a problem that the glue from the battery cell part overflows into the electrical module part and damages the connector.

DETAILED DESCRIPTION

[0039] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0040] Reference Figure 1-Figure 5The battery pack is exemplarily shown in the disclosure, which comprises a shell 1, a battery unit 2 arranged in the shell 1, a first electronic module 3 arranged in the shell 1 and located at one side of the battery unit 2, and a sealing part 4 arranged in the shell 1. The battery unit 2 can comprise one or more battery cells, and the battery cells can be connected in series or in parallel with each other. The first electronic module 3 can be a CMU (Cell Monitor Unit), which is responsible for measuring parameters such as voltage, current and temperature of the battery pack, and has functions such as balancing, or it can also be a communication module, a control module, etc. The first electronic module 3 has a first connector 31 for electrical connection with the battery unit 2, which can be a plug-in terminal formed on the first electronic module 3, etc., and can be electrically connected with the battery unit 2 through a connection wire harness, or can also be electrically connected with the battery unit 2 through the second electronic module 6 to be mentioned below, which is not limited in the disclosure, and the specific connection form can be referred to below. When the first electronic module 3 is a CMU, the electrical connection between the first connector 31 and the battery unit 2 is a sampling connection. The sealing part 4 separates the first space 101 and the second space 102 located on both sides of the sealing part 4 in the shell 1, and the first connector 31 is located in the first space 101.

[0041] In the embodiment of the disclosure, the sealing part 4 can abut between the shell 1 and the battery unit 2, or can also abut between the first electronic module 3 and the shell 1, or can also be located between the battery unit 2 and the first electronic module 3, as long as it can separate the first space 101 and the second space 102. The sealing part 4 is not limited in the disclosure, which can be a rubber strip, a silica gel strip, foam, a sealing plate, etc., as long as it can have the effect of separating the first space 101 and the second space 102, and its specific structure and material will be introduced below.

[0042] By using the above technical solution, by arranging the sealing part 4 in the shell 1, the first space 101 and the second space 102 located on both sides of the sealing part 4 in the shell 1 can be separated from each other, so that when the battery pack is filled with glue, the filling of the first space 101 and the second space 102 can be controlled separately according to the specific situation of the two spaces, that is, the two spaces can be separately filled and controlled according to the different filling needs of the two spaces, and the operability is better. For example, the second space 102 can be filled with filling glue to fill the filling glue between the battery unit 2 and the shell 1, so as to improve the stability and strength of the battery unit 2, and the sealing part 4 can prevent the filling glue in the second space 102 from overflowing to the first connector 31 in the first space 101; when the first space 101 is filled with filling glue, the height of the filling glue can be controlled to be lower than the first connector 31, so as to ensure the stability of the related components in the first space 101 while avoiding damage to the first connector 31 caused by the filling glue.

[0043] As described above, in the embodiment of the present disclosure, the first space 101 and the second space 102 can be respectively filled with filling glue 5, and the filling glue 5 can be foamed glue or non-foamed glue. Among them, the height of the filling glue 5 in the first space 101 can be lower than the first connector 31, so as to ensure the connection strength of the relevant components in the first space 101 and avoid the filling glue 5 being too high and affecting the first connector 31. It should be noted that if the filling glue 5 is foamed glue, the height of the filling glue 5 here refers to the height of the filling glue 5 after it is completely foamed and shaped. The second space 102 can be filled with filling glue 5, so that the space between the battery cell 2 and the shell 1 is filled with filling glue 5 to ensure the connection strength and stability of the battery cell 2, and the sealing portion 4 can prevent the filling glue 5 in the second space 102 from overflowing into the first space 101 and affecting the first connector 31. The present disclosure uses the sealing portion 4 to isolate the first space 101 and the second space 102, so that the two spaces can be filled with glue separately, avoiding the filling glue 5 in the two spaces from affecting each other. The above-mentioned “the second space 102 can be filled with filling glue 5” means that in the second space 102, the filling glue 5 can fill all empty areas, including the gaps within the battery cell 2 itself, the gaps between the battery cell 2 and the connection circuit 61 mentioned below, the gaps between the battery cell 2 and the frame of the tray 11 mentioned below, and the gaps between the battery cell 2 and the upper cover 12 mentioned below, etc.

[0044] Furthermore, in an embodiment of the present disclosure, the housing 1 may be provided with at least two filling ports (not shown in the figures), and the distance between the filling ports and the sealing portion 4 may be greater than or equal to 5 mm. The two filling ports may be used to pour glue into the corresponding one of the first space 101 and the second space 102, respectively. By configuring the distance between the filling port and the sealing portion 4 to be greater than or equal to 5 mm, it is possible to avoid the filling glue 5 being too close to the sealing portion 4 during pouring, thereby preventing the sealing effect of the sealing portion 4 from being affected, for example, by deformation or displacement of the sealing portion 4 under the action of the foaming force. The number of filling ports may be two, three, four, etc., as long as there is at least one filling port corresponding to each of the first space 101 and the second space 102.

[0045] Reference Figure 1-Figure 5In the embodiments of the present disclosure, the sealing portion 4 can be disposed at an end position of the battery cell 2 near the first electronic module 3 and surround the battery cell 2. Here, "end position near the first electronic module 3" refers to a position near the first electronic module 3 on a wall surface (e.g., a side wall, top wall, bottom wall, etc.) of the battery cell 2 extending along the arrangement direction of the battery cell 2 and the first electronic module 3. The portion of the battery cell 2 corresponding to the sealing portion 4 and the sealing portion 4 together divide the internal space of the housing 1 into a first space 101 and a second space 102. That is, the majority of the battery cell 2 is located within the second space 102, while the portion of the battery cell 2 corresponding to the sealing portion 4 is located at the junction of the first space 101 and the second space 102. This position completely isolates the battery cell 2 portion from the first electronic module 3 on the other side, further facilitating the separate control of the glue injection volume in the two spaces.

[0046] Reference Figure 2-Figure 4 In an embodiment of the present disclosure, the battery cell 2 can be sealed against the bottom of the shell 1, thereby forming an "inverted U-shaped" gap between the top wall and two side walls of the battery cell 2 and the shell 1. The sealing portion 4 can include two first rubber strips 41 extending along the height direction of the battery cell 2 and sealingly connected between the side walls of the battery cell 2 and the shell 1, and a second rubber strip 42 sealingly connected between the top wall of the battery cell 2 and the shell 1. The second rubber strip 42 extends along the arrangement direction of the two side walls of the battery cell 2. The two first rubber strips 41 and the second rubber strip 42 can seal the aforementioned "gantry-shaped" gap, thereby isolating the first space 101 from the second space 102. In an embodiment of the present disclosure, the two first rubber strips 41 and the second rubber strip 42 can be a single piece, or the two first rubber strips 41 and the second rubber strip 42 can be separate units. During installation, the three are installed in their respective positions, with the adjacent two rubber strips abutting against each other, thereby completely sealing the aforementioned "gap."

[0047] The present disclosure does not limit the structure of the housing 1. In an embodiment of the present disclosure, the housing 1 may include a tray 11 and an upper cover 12 covering the tray 11. The first rubber strip 41 may be disposed between the side walls of the battery cell 2 and the side walls of the tray 11, and the second rubber strip 42 may be disposed between the top wall of the battery cell 2 and the upper cover 12. By interferingly positioning the rubber strips between the battery cell 2 and the housing 1, a sealing effect is ensured. The housing 1 having the tray 11 and the upper cover 12 facilitates removal of the upper cover 12 for inspection and maintenance of the battery pack.

[0048] In the embodiment of the present disclosure, the upper cover 12 can be connected to the battery cells 2 via a filler 5 and to the tray 11 via fasteners and a sealant. The tray 11 primarily supports the battery cells 2 and the first electronic module 3, and is fixedly connected to the battery cells 2, the first electronic module 3, etc. via the filler 5.

[0049] In the embodiment of the present disclosure, the two first rubber blocking strips 41 can be elastically pressed between the side walls of the battery cell 2 and the housing 1. The second rubber blocking strip 42 can be elastically pressed between the top wall of the battery cell 2 and the housing 1. The elastic pressing can provide the rubber blocking strips with an elastic restoring force, which can keep the rubber blocking strips tightly pressed between the battery cell 2 and the housing 1, thereby improving their sealing performance.

[0050] The present disclosure does not limit the materials of the first rubber block strip 41 and the second rubber block strip 42. For example, in an embodiment of the present disclosure, the first rubber block strip 41 and the second rubber block strip 42 can be made of rubber or foam, respectively. The above-mentioned rubber and foam can be, for example, semi-hard rubber block foam or semi-hard rubber block rubber. For example, the Shore hardness range can be Shore A 30~Shore D 50. The rubber and foam can specifically be, for example, Si-based, PU-based, EPDM, CR, EVA, EPP, MPP, XPE and SBR, etc., prepared alone or in combination, but the present disclosure is not limited thereto. By configuring the first rubber block strip 41 and the second rubber block strip 42 as the aforementioned materials, it can be ensured that they have good elasticity and sealing properties, so that when they are interference-fitted into the corresponding gap, they can have a good sealing effect.

[0051] Reference Figure 3 and Figure 5In an embodiment of the present disclosure, the battery pack may further include a second electronic module 6, which may include a connection circuit 61 electrically connected to the battery cell 2 and a second connector 62 electrically connected to the connection circuit 61, such as a plug-in terminal. The second connector 62 may be located in the first space 101 and electrically connected to the first connector 31. Most of the connection circuit 61 may be located at the top of the battery cell 2 and electrically connected to the battery cell 2, and one end of the connection circuit 61 may extend to the first space 101 and be installed with the second connector 62. The second connector 62 may be directly plugged into the first connector 31 to form an electrical connection, or may be connected through a low-voltage wiring harness to form an electrical connection. The connection circuit 61 may be an FPC (Flexible Printed Circuit) or an FFC (Flexible Flat Cable). The second electronic module 6 is provided to achieve electrical connection between the first electronic module 3 and the battery cell 2. The second connector 62 is disposed within the first space 101. Similar to the first connector 31, the height of the filling glue 5 can be controlled to be lower than the first connector 31 and the second connector 62 when filling the first space 101, thereby preventing damage to the first connector 31 and the second connector 62. Furthermore, the sealing portion 4 prevents the filling glue 5 in the second space 102 from overflowing into the first space 101 and damaging the two connectors.

[0052] In some embodiments, the second connector 62 can be directly connected to the end of the connection circuit 61. Figure 5 In the illustrated embodiment, the second electronic module 6 may further include an adapter plate 63, which may be connected to the connection circuit 61. One end of the adapter plate 63 may overlap the top wall of the battery cell 2, while the other end of the adapter plate 63 may extend into the first space 101 and be configured as a cantilevered end. The second connector 62 may be provided on the adapter plate 63, and the first connector 31 and the second connector 62 may be connected via a wiring harness. The adapter plate 63 may be a PCB (Printed Circuit Board). The first electronic module 3 may be electrically connected to the battery cell 2 via the first connector 31, wiring harness, second connector 62, adapter plate 63, and connection circuit 61. The adapter plate 63 enhances circuit functionality and simplifies internal wiring.

[0053] In the case that the second electronic module 6 comprises the adapter plate 63, the second glue blocking strip 42 can comprise a first sub-glue strip 421 and a second sub-glue strip 422 stacked in the height direction, the first sub-glue strip 421 can abut against the top wall of the battery cell 2, and the second sub-glue strip 422 can abut against the top shell of the shell 1, and the adapter plate 63 is sealingly clamped between the first sub-glue strip 421 and the second sub-glue strip 422. Due to the filling glue 5 entering the inside of the connector or the plate surface of the adapter plate, there is a risk of poor electrical connection contact, additional pressure stress / tension, etc. Therefore, the first sub-glue strip 421 can prevent the filling glue 5 on the lower side of the adapter plate 63 from overflowing to the adapter plate 63 and the second connector 62, and the second sub-glue strip 422 can prevent the filling glue 5 on the upper side of the adapter plate 63 from overflowing to the adapter plate 63 and the second connector 62. By arranging the second glue blocking strip 42 to comprise two sub-glue strips and clamping the adapter plate 63 between the two sub-glue strips, the two sides of the adapter plate 63 can be elastically sealed and abutted by the glue blocking strip, ensuring that the two sides of the adapter plate 63 do not overflow. The two sub-glue strips are in sealing abutment with the top shell and the battery cell 2 respectively, thereby ensuring that the positions connected with the top shell and the battery cell 2 are also sealed, avoiding the existence of gaps that cause overflow.

[0054] Referring to Figure 1 In the embodiments of the present disclosure, the number of second electronic modules 6 can be multiple and arranged in sequence. In this way, each adapter plate 63 can be sealingly clamped between two sub-glue strips to achieve a sealing effect. The present disclosure can achieve sealing design for multiple adapter plates 63 through two sub-glue strips, which protects the adapter plate 63 and the second connector 62 from being sealed, without the need to design a seal for each adapter plate 63, which is beneficial to simplify the structure and reduce the cost.

[0055] In order to ensure the sealing effect of the first sub-glue strip 421, the second sub-glue strip 422 and the first glue blocking strip 41, in the embodiments of the present disclosure, the first sub-glue strip 421, the second sub-glue strip 422 and the first glue blocking strip 41 can be arranged with an interference in the corresponding gap. Specifically, in the height direction of the battery cell 2, the size compression of the first sub-glue strip 421 and the second sub-glue strip 422 can be greater than or equal to 10% and less than or equal to 90%, specifically 10%, 20%, 30%, 40%, 50%, 90%, etc. Similarly, in the lateral direction of the battery cell 2 (the arrangement direction of the two side walls), the size compression of the first glue blocking strip 41 can be greater than or equal to 10% and less than or equal to 90%, specifically 10%, 15%, 30%, 50%, 90%, etc. Here, the lower limit of the compression amount of each glue strip is to ensure that it has sufficient elastic force, thereby ensuring the required sealing effect, and the upper limit of the compression amount of each glue strip is to avoid the glue strip from being compressed too much and being invalid, and to avoid hard damage to the battery cell 2 or the shell 1.

[0056] Similarly, to ensure the sealing effect of the rubber barrier strip, in the embodiment of the present disclosure, along the arrangement direction of the first space 101 and the second space 102, the dimensions of the first sub-strip 421 and the second sub-strip 422 can be greater than or equal to 5 mm and less than or equal to 10 mm, for example, 5 mm, 7.5 mm, 10 mm, etc. The reason for setting an upper limit on the dimensions of the first sub-strip 421 and the second sub-strip 422 along the arrangement direction of the first space 101 and the second space 102 is to avoid interference between the two sub-strips and components (such as the connecting circuit 61) located at the top of the battery cell 2 in the second space 102. Similarly, along the arrangement direction of the first space 101 and the second space 102, the dimension of the first rubber barrier strip 41 can be greater than or equal to 5 mm, for example, 5 mm, 10 mm, 15 mm, etc., to ensure the sealing effect.

[0057] In the embodiment of the present disclosure, in order to avoid displacement of the first sub-strip 421 and the second sub-strip 422, in the embodiment of the present disclosure, the first sub-strip 421 can be bonded to the battery cell 2 and the adapter plate 63, the second sub-strip 422 can be bonded to the adapter plate 63, and the second sub-strip 422 and the upper cover 12 of the shell 1 are only simply abutted against each other, and there is no "bonding", so as to facilitate opening the upper cover 12 and inspecting the inside of the shell 1. The aforementioned "bonding" can form the battery cell 2, the first sub-strip 421, the adapter plate 63 and the second sub-strip 422 into a whole, thereby improving the stability of the sealing part 4. The aforementioned "bonding" can be achieved by applying glue, or it can be achieved by sticking adhesive on the corresponding surface of the sub-strip, and the present disclosure does not limit this.

[0058] According to a second aspect of the present disclosure, a vehicle is provided, comprising the above-mentioned battery pack. Since the vehicle has all the beneficial effects of the above-mentioned battery pack, they are not described in detail here.

[0059] In the foregoing detailed description, reference is made to the accompanying drawings, which illustrate, by way of illustration, specific aspects of the present disclosure in which it may be practiced. In this regard, terms indicating directions or expressing positional relationships, such as "center," "longitudinal," "lateral," "length," "width," "thickness," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," "clockwise," "counterclockwise," "axial," "radial," "circumferential," etc., may be used with reference to the orientation of the figures being described. Since the components of the described devices may be positioned in a plurality of different orientations, the directional terms may be used for illustrative purposes rather than restrictive. It should be understood that other aspects may be utilized and structural or logical changes may be made without departing from the concepts of the present disclosure. Therefore, the following detailed description should not be taken in a limiting sense.

[0060] It should be understood that, unless otherwise specifically noted, the features of the various embodiments of the present disclosure described herein may be combined with each other. As used herein, the term "and / or" includes any one of the relevant listed items and any combination of any two or more thereof; similarly, "at least one of" includes any one of the relevant listed items and any combination of any two or more thereof.

[0061] It should be understood that, unless otherwise expressly specified or limited, the terms "join," "attach," "install," "connect," "connect," "fix," etc. used in the embodiments of the present disclosure should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrated; they can be mechanically connected, electrically connected, or communicable with each other; they can be directly connected, or indirectly connected through an intermediate medium, and they can be internally connected between two elements or an interactive relationship between two elements, unless otherwise expressly limited. For those skilled in the art, the specific meanings of the above terms in this article can be understood according to specific circumstances.

[0062] Additionally, the term "over" as used in reference to a component, element, or material layer being formed "over" or located "over" a surface may be used herein to mean that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are disposed between the surface and the component, element, or material layer. However, the term "over" as used in reference to a component, element, or material layer being formed "over" or located "over" a surface may alternatively have a specific meaning: the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, e.g., in direct contact with the surface.

[0063] Although terms such as "first", "second" and "third" may be used herein to describe various components, parts, regions, layers or sections, these components, parts, regions, layers or sections are not limited to these terms. On the contrary, these terms are only used to distinguish one component, part, region, layer or section from another component, part, region, layer or section. Therefore, without departing from the teachings of each example, the first component, part, region, layer or section mentioned in the examples described herein may also be referred to as the second component, part, region, layer or section. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include at least one such feature. In the description herein, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0064] It should be understood that spatially relative terms, such as "above," "upper," "below," and "lower," are used herein to describe the relationship of one element to another element shown in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as being "above" or "upper" relative to another element would then be "below" or "lower" relative to the other element. Thus, the term "above" encompasses both above and below orientations, depending on the spatial orientation of the device. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein should be interpreted accordingly.

[0065] Furthermore, the word "exemplary" is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous over other aspects or designs. Rather, the use of the word exemplary is intended to present concepts in a concrete manner. As used herein, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or." That is, unless otherwise specified or clear from the context, "X applies to A or B" is intended to mean any of the natural inclusive permutations. That is, if X applies to A; X applies to B; or X applies to both A and B, then "X applies to A or B" satisfies any of the aforementioned instances. Furthermore, the articles "a" and "an," as used in this application and the appended claims, are generally understood to mean "one or more," unless otherwise specified or clear from the context to refer to the singular form.

[0066] Likewise, although the present disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. The present disclosure includes all such modifications and variations and is limited only by the scope of the claims. With particular regard to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, terms used to describe such components are intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if not structurally equivalent to the disclosed structure. In addition, although particular features of the present disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations as may be desired and advantageous for any given or particular application. Furthermore, to the extent that the terms "include," "have," "have," "have," or variations thereof are used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term "comprising."

[0067] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered as exemplary only, with the true scope and spirit of the present disclosure being indicated by the appended claims.

[0068] It should be understood that the present disclosure is not limited to the exact structures that have been described above and shown in the drawings, and that various modifications and changes can be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
