[0022] The following disclosure provides many different implementations or examples for carrying out different structures of this application. To simplify the disclosure of this application, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit this application.

[0023] The battery module includes multiple individual cells and a sampling circuit. The sampling circuit, connected to the connector, can collect information such as voltage and temperature of the individual cells and transmit it to the battery management system.

[0024] However, when the conductor is connected to the connecting piece, it bends toward the connecting piece to extend toward and connect with the connecting piece, which increases the difficulty of connecting the connecting piece and the conductor.

[0025] To address the technical challenge of connecting the connector 200 and the conductor 320, the first embodiment of this application provides a battery module. (See also...) Figure 1 , Figure 2 and Figure 3 The battery module includes multiple individual cells 100, a connecting piece 200, and a data acquisition component 300. At least some of the individual cells 100 are arranged along a first direction X. Each individual cell 100 includes a cover plate 110 and a terminal post 120, with the terminal post 120 passing through the cover plate 110. The connecting piece 200 connects the terminal posts 120 of adjacent individual cells 100. The data acquisition component 300 includes a connector 310 and a conductor 320. The conductor 320 extends along the first direction X and is connected to the side of the connecting piece 200 facing the cover plate 110. One end of the conductor 320 along the first direction X is connected to the connector 310.

[0026] Specifically, the connecting piece 200 connects multiple individual cells 100 in series.

[0027] Each individual cell 100 in the battery module is connected to the connector 310 via a connecting piece 200 and at least one conductor 320, so that information from each individual cell 100 can be output through the acquisition component 300.

[0028] In some embodiments, a plurality of individual cells 100 are arranged along a first direction X; in some embodiments, please refer to Figure 1 Some of the individual cells 100 are arranged along the first direction X, and some of the individual cells 100 are arranged along the second direction Y; in some embodiments, the multiple individual cells 100 are arranged in a matrix about the first direction X and the second direction Y.

[0029] In some embodiments, the conductor 320 is welded to the connecting piece 200.

[0030] Firstly, it is understandable that the gap between the connecting piece 200 and the cover plate 110 is small, and the conductor 320 disposed in the gap only needs slight bending to connect with the connecting piece 200. In the above embodiment, by disposing the conductor 320 in the acquisition component 300 within the gap between the connecting piece 200 and the cover plate 110, the conductor 320 can be allowed to contact and be connected with the connecting piece 200 without undergoing large-angle bending, thereby reducing the difficulty of connecting the connecting piece 200 and the conductor 320. Specifically, it reduces the difficulty of positioning the connecting piece 200 and the conductor 320 before welding.

[0031] Secondly, in the above embodiments, the connection direction of the connecting piece 200 and the conductor 320 is the same as the position direction. The connection between the connecting piece 200 and the conductor 320 is less prone to additional shearing forces, making the connection between them more reliable. Simultaneously, the reduced likelihood of additional shearing forces and the more reliable connection also eliminates the need for the battery module to add nickel sheets to the connecting piece 200 and conductor 320 support brackets to improve connection reliability, thereby further reducing the connection difficulty between the connecting piece 200 and the conductor 320.

[0032] Thirdly, in the above embodiments, placing the conductor 320 between the connecting piece 200 and the cover plate 110 allows the conductor 320 to be as far away from the explosion-proof valve 130 as possible along the second direction Y, reducing the possibility that the connecting piece 200 may block or hinder the release of high-pressure gas in the explosion-proof valve 130, thereby improving the safety performance of the battery module.

[0033] In some embodiments, please refer to Figure 1 The single cell 100 also includes an explosion-proof valve 130, which is connected to the cover plate 110. The explosion-proof valve 130 and the terminal post 120 are spaced apart along the second direction Y. The explosion-proof valve 130 and the acquisition component 300 are staggered along the third direction Z. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0034] Specifically, the cover plate 110 has a first surface 111 on the side facing the connecting piece 200. The fact that the explosion-proof valve 130 and the acquisition component 300 are intersected along the third direction Z means that, along the third direction Z, there is no overlap between the orthographic projection of the acquisition component 300 on the plane where the first surface 111 is located and the orthographic projection of the explosion-proof valve 130 on the plane where the first surface 111 is located.

[0035] In some embodiments, along the third direction Z, the orthographic projection of the acquisition component 300 onto the plane containing the first surface 111 and the orthographic projection of the explosion-proof valve 130 onto the plane containing the first surface 111 are spaced apart. That is, not only is there no overlapping area, but there is also a gap between their orthographic projections.

[0036] In the above embodiments, by making the explosion-proof valve 130 and the acquisition component 300 staggered in the third direction Z, the possibility of the high-pressure gas leaking from the explosion-proof valve 130 being blocked or obstructed by the acquisition component 300 is reduced, thereby improving the safety performance of the battery module.

[0037] In some embodiments, the connecting piece 200 and the explosion-proof valve 130 are staggered along the third direction Z, that is, along the third direction Z, the orthographic projection of the connecting piece 200 on the plane where the first surface 111 is located and the orthographic projection of the explosion-proof valve 130 on the plane where the first surface 111 is located do not overlap, so as to reduce the possibility that the high-pressure gas leaking out of the explosion-proof valve 130 is blocked or obstructed by the collection component 300.

[0038] In some embodiments, please refer to Figure 1 and Figure 2 The single cell 100 includes multiple terminals 120, each terminal 120 including a first terminal 121 and a second terminal 122, which are spaced apart along a second direction Y. The battery module includes multiple connecting pieces 200, each connecting piece 200 including a first connecting piece 220 and a second connecting piece 230. The first connecting piece 220 connects to the first terminal 121 of an adjacent single cell 100 along a first direction X; the second connecting piece 230 connects to the second terminal 122 of an adjacent single cell 100 along a first direction X. The acquisition component 300 includes multiple conductors 320, each conductor 320 including a first conductor 331 and a second conductor 341, where the first conductor 331... One end is connected to the first connecting piece 220, and the other end is connected to the connector 310; one end of the second conductor 341 is connected to the second connecting piece 230, and the other end is connected to the connector 310; the first conductor 331 and the second conductor 341 are spaced apart along the second direction Y; the cover plate 110 has a first surface 111 on the side facing the connecting piece 200; along the third direction Z, the orthographic projection of the explosion-proof valve 130 on the plane where the first surface 111 is located is the first orthographic projection, the orthographic projection of the first conductor 331 on the plane where the first surface 111 is located is the second orthographic projection, and the orthographic projection of the second conductor 341 on the plane where the first surface 111 is located is the third orthographic projection, and the first orthographic projection is located between the second orthographic projection and the third orthographic projection.

[0039] It is understood that, of the two first terminals 121 connected to the first connecting piece 220, one is the positive terminal 120 and the other is the negative terminal 120; of the two second terminals 122 connected to the second connecting piece 230, one is the positive terminal 120 and the other is the negative terminal 120; in the same single battery cell 100, the polarities of the first terminals 121 and the second terminals 122 are opposite. The battery module connects multiple single batteries 100 in series through the first connecting piece 220 and the second connecting piece 230.

[0040] It is understood that the acquisition component 300 needs to be equipped with multiple conductors 320 to connect to each connecting piece 200, and the connecting piece 200 includes a first connecting piece 220 and a second connecting piece 230 located on both sides of the explosion-proof valve 130. In the above embodiment, the conductor 320 is divided into a first conductor 331 and a second conductor 341 located on both sides of the explosion-proof valve 130 to connect to the first connecting piece 220 and the second connecting piece 230 located on both sides of the explosion-proof valve 130, which allows the first conductor 331 and the second conductor 341 to connect to the first connecting piece 220 or the second connecting piece 230 on the same side of themselves, thereby preventing the conductor 320 from crossing the explosion-proof valve 130 from one side to the other side and connecting to the connecting piece 200 on the other side, thereby reducing the possibility of the conductor 320 obstructing the explosion-proof valve 130 and improving the safety performance of the battery module.

[0041] In some embodiments, please refer to Figure 1 and Figure 4 The acquisition component 300 also includes a third conductor 351, one end of which is connected to one end of the first conductor 331, and the other end of the third conductor 351 away from the first conductor 331 is connected to the connector 310. A portion of the third conductor 351 extends along the second direction Y toward the second conductor 341.

[0042] In the above embodiment, by providing a third conductor 351 having a portion extending along the second direction Y, such that the portion of the conductor 320 for connecting the first connecting piece 220 and the connector 310, which is spaced apart from the second conductor 341 along the second direction Y, can be close to the portion of the second conductor 341 and the connector 310 connected in the second direction Y, thereby allowing the connector 310 to have a smaller size in the second direction Y.

[0043] In some embodiments, when the acquisition component 300 includes a third conductor 351, the second conductor 341 also has a fourth conductor 320, one end of the fourth conductor 320 being connected to one end of the second conductor 341, the other end of the fourth conductor 320 being connected to a connector 310 away from the second conductor 341, and a portion of the fourth conductor 320 extending toward the second conductor 341 along a second direction Y.

[0044] In the above embodiments, by providing a third conductor 351 and a fourth conductor 320, and by adjusting the length of the third conductor 351 extending along the second direction Y and the length of the fourth conductor 320 extending along the second direction Y respectively, the position of the connector 310 in the second direction Y can be adjusted, thereby facilitating the use of the connector 310.

[0045] In some embodiments, please refer to Figure 1 , Figure 4 and Figure 5 The battery module includes multiple first connecting pieces 220, which are spaced apart along a first direction X; the battery module also includes multiple second connecting pieces 230, which are spaced apart along the first direction X; the acquisition component 300 includes a first conductor group 330 and a second conductor group 340. The first conductor group 330 is disposed between the first connecting pieces 220 and the cover plate 110 and is connected to the multiple first connecting pieces 220. The first conductor group 330 includes multiple first conductors 331, which are spaced apart along a second direction Y; the second conductor group 340 is disposed between the second connecting pieces 230 and the cover plate 110 and is connected to the multiple second connecting pieces 230. The second conductor group 340 includes multiple second conductors 341, which are spaced apart along the second direction Y.

[0046] It is understandable that by setting multiple first connecting pieces 220 and multiple second connecting pieces 230, it is possible to allow at least three individual cells 100 arranged along the first direction X in the battery module to be connected in series.

[0047] In some embodiments, the battery module includes a plurality of first connecting pieces 220, at least a portion of which extend at intervals along a first direction X, and each first connecting piece 220 is connected to the connector 310 via at least one first conductor 331; the battery module includes a plurality of second connecting pieces 230, at least a portion of which are spaced at intervals along a second direction Y, and each second connecting piece 230 is connected to the connector 310 via at least one second conductor 341.

[0048] In the above embodiments, since the plurality of first conductors 331 are spaced apart along the second direction Y and since each first conductor 331 is connected to the side of the first connecting piece 220 facing the cover plate 110, the distance between each first conductor 331 and each connecting piece 200 is similar, and they can all be connected to the first connecting piece 220 with only a small warp, further reducing the difficulty of connecting the first conductor 331 and the first connecting piece 220. Similarly, since the plurality of second conductors 341 are spaced apart along the second direction Y and since each second conductor 341 is connected to the side of the second connecting piece 230 facing the cover plate 110, the distance between each second conductor 341 and each connecting piece 200 is similar, and they can all be connected to the second connecting piece 230 with only a small warp, further reducing the difficulty of connecting the second conductor 341 and the second connecting piece 230.

[0049] In some embodiments, the acquisition component 300 further includes a third conductor group 350, which includes a plurality of third conductors 351.

[0050] In some embodiments, please refer to Figure 5 Both the first conductor group 330 and the second conductor group 340 are flexible flat cables.

[0051] Specifically, the flexible flat cable is FFC.

[0052] Specifically, the first conductor group 330 includes a plurality of first conductors 331 and a first insulating member. The first insulating member has a plurality of first insulating holes spaced apart along the second direction Y. The first conductors 331 pass through the first insulating holes, and adjacent first conductors 331 are insulatedly connected through the first insulating member. The second conductor group 340 includes a plurality of second conductors 341 and a second insulating member. The second insulating member has a plurality of second insulating holes spaced apart along the second direction Y. The second conductors 341 pass through the second insulating holes, and adjacent second conductors 341 are insulatedly connected through the second insulating member.

[0053] In the above embodiments, using the first conductor group 330 and the second conductor group 340 as the cable for the acquisition component 300 can reduce the manufacturing difficulty of the acquisition component 300 by using the pre-compression connector 310 compared to using a flexible circuit board as the cable for the acquisition component 300.

[0054] In some embodiments, please refer to Figure 1 The battery module also includes a hot-pressing film 400, which is connected to the side of the connecting piece 200 near the housing. The hot-pressing film 400 is connected to the first conductor 331 and the second conductor 341 respectively.

[0055] In some embodiments, the hot press film 400 has a through hole 410. Along the third direction Z, the orthographic projection of the explosion-proof valve 130 on the plane of the side of the hot press film 400 near the cover plate 110 is located in the through hole 410, so that the gas leaking out of the explosion-proof valve 130 can pass through the hot press film 400 through the through hole 410.

[0056] In some embodiments, the first electrode post 121 and the second electrode post 122 are respectively disposed in the hot-pressing film 400.

[0057] In the above embodiments, by setting a hot-pressing film 400 to integrate the first conductor 331, the second conductor 341, the first connecting piece 220, and the second connecting piece 230 into a component, the assembly of the battery module is facilitated and the integration level of the battery module is improved.

[0058] In some embodiments, a portion of the first conductor 331 is located on the side of the hot-pressing film 400 away from the first connecting piece 220, and the portion of the first conductor 331 passes through the hot-pressing film 400 and is welded to the first connecting piece 220; a portion of the second conductor 341 is located on the side of the hot-pressing film 400 away from the second connecting piece 230, and the portion of the second conductor 341 passes through the hot-pressing film 400 and is welded to the second connecting piece 230.

[0059] In some embodiments, please refer to Figure 4 The connecting piece 200 has a second surface 210 facing the cover plate 110, and the pole post 120 is connected to the second surface 210; along the third direction Z, the orthographic projection of the portion of the conductor 320 along the first direction X onto the plane where the second surface 210 is located is within the second surface 210.

[0060] Specifically, the conductor 320 does not exceed the two sides of the connecting piece 200 connected to it along the second direction Y.

[0061] In the above embodiment, by limiting the positional relationship between the conductor 320 and the connecting piece 200 connected thereto along the second direction Y, the conductor 320 can be further moved away from the explosion-proof valve 130, reducing the possibility of the conductor 320 blocking the explosion-proof valve 130 and improving the safety performance of the battery module.

[0062] In some embodiments, please refer to Figure 1 , Figure 4 and Figure 6The battery module includes a plurality of individual cells 100 arranged along the second direction Y; the plurality of connecting pieces 200 also include a third connecting piece 240, wherein in at least two individual cells 100 arranged along the second direction Y, the first terminal 121 of one and the second terminal 122 of the other are connected to the third connecting piece 240; the battery module also includes at least two acquisition components 300, wherein the first conductor 331 of one of the acquisition components 300 is connected to the third connecting piece 240, and the second conductor 341 of the other is connected to the third connecting piece 240.

[0063] Specifically, multiple individual battery cells 100 are arranged along the first direction X to form a battery column, and the battery module includes multiple acquisition components 300 spaced apart along the second direction Y. Each acquisition component 300 is used to acquire information of individual battery cells 100 in a battery column.

[0064] In the two acquisition components 300, the first conductor 331 of one and the second conductor 341 of the other are connected to the third connecting piece 240.

[0065] In the above embodiment, a third connecting piece 240 is provided to connect two individual battery cells 100 arranged in series along the second direction Y. At the same time, the third connecting piece 240 connects two acquisition components 300 respectively to further prevent the acquisition components 300 from crossing the explosion-proof valve 130 along the second direction Y, thereby reducing the possibility of the acquisition components 300 obstructing the explosion-proof valve 130 and improving the safety performance of the battery module.

[0066] Accordingly, this application also provides a vehicle including a battery module as described in any of the above embodiments.
