[0003] However, when battery packs are used in vehicles and other equipment, the overall thickness is subject to significant limitations, which restricts the length of the battery cells and affects their capacity. Utility Model Content
[0004] This application provides a cell module and battery pack, which facilitates flexible adjustment of the cell length according to requirements, thereby adjusting the cell capacity.
[0005] On one hand, this application provides a battery cell module, including: a fixing plate, wherein at least two rows of slots are provided on both sides of the fixing plate along a first direction, the slots are arranged along a second direction, and the slots include a plurality of fixed slots arranged along a third direction; a plurality of battery cells, each battery cell corresponding to a fixed slot, and the sidewall of the battery cell is at least partially connected to the slot wall of the fixed slot; the first direction, the second direction and the third direction are perpendicular to each other.
[0006] In one possible implementation, the battery cell is cylindrical, the fixing groove is an arc-shaped groove, and the arc-shaped groove is coaxially arranged with the battery cell; and / or, the fixing grooves located on opposite sides of the fixing plate along the first direction are staggered along the third direction.
[0007] In one possible implementation, a support member is also included, which is disposed between the side wall of the battery cell and the fixing groove to create a gap between the side wall of the battery cell and the fixing groove.
[0008] In one possible implementation, the support includes a first support and a second support; the first support and the second support are respectively fixed at both ends of the fixing groove along the second direction, and both the first support and the second support are connected to the side wall of the battery cell; the first support, the second support, the battery cell and the fixing groove together define a fixing space, and the fixing space is used to fill structural adhesive.
[0009] In one possible implementation, the fixing groove has two rows along the second direction; the end of the battery cell along the second direction has a tab, and the ends of the two rows of battery cells with tabs located on the same side of the fixing plate are arranged opposite to each other.
[0010] In one possible implementation, a liquid cooling plate is also included; the liquid cooling plate is located between two rows of cells along the second direction, and the end of the cell away from the tab is connected to the liquid cooling plate.
[0011] In one possible implementation, an insulating plate is also included; the insulating plate is connected to one end of the battery cell where the tabs are located.

[0015] The battery cell module and battery pack provided in this application fix the battery cells by setting a fixing plate.

The side wall of the battery cell is at least partially connected to the fixing groove. The fixing plate is parallel to the bottom of the battery pack shell. In this way, after the battery cell is fixed on the fixing plate, the length of the battery cell extends along the second direction. When it is necessary to adjust the length of the battery cell, the battery cell module will only increase its length in the second direction. When the number of battery cells is increased, the length of the battery cell module will increase in the third direction. Neither will affect the thickness of the battery cell module in the first direction. Since the battery pack is mainly limited by the space in the first direction during application, the battery cell module provided in this application can flexibly adjust the length of the battery cells according to different requirements for battery cell capacity, which is conducive to improving the flexibility of battery cell setting and expanding the applicability of the battery pack.

[0028] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation
[0029] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0030] As shown in the background section, in the prior art, a battery pack is an integral unit assembled from multiple cells for storing and providing electrical energy. In the prior art, the bottom of each cell is fixedly connected to the bottom of the battery pack casing, thereby fixing it inside the battery pack.
[0031] When battery packs are actually put into use, the length of the cells usually needs to be adjusted according to different capacity requirements. However, when battery packs are used in vehicles and other equipment, the overall thickness of the battery pack is greatly restricted, which limits the length of the cells and makes it impossible to adjust them flexibly, thus affecting the capacity of the cells.
[0032] To address the aforementioned technical problems, this application provides a cell module and a battery pack. The cell module includes a fixing plate and multiple cells. The fixing plate has slots arranged along a second direction on both sides along a first direction. Each slot includes multiple fixing slots arranged along a third direction. The cell module fixes the cells using the fixing plate, and the fixing slots on the fixing plate secure each cell to a specific position, preventing displacement due to rolling and improving the stability of the connection between the cell and the fixing plate. At least part of the sidewall of the cell is connected to the fixing slot. The fixing plate is parallel to the bottom of the battery pack housing. Thus, after the cell is fixed to the fixing plate, its length extends along the second direction. When the cell length needs adjustment, the cell module only increases its length in the second direction. Increasing the number of cells increases the length in the third direction, without affecting the thickness of the cell module in the first direction. Since the battery pack is mainly limited by space in the first direction during application, the cell module provided in this application can flexibly adjust the cell length according to different cell capacity requirements, which is beneficial for improving the flexibility of cell arrangement and expanding the applicability of the battery pack.
[0033] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings:
[0034] It should be noted that the cell module provided in this application embodiment can be applied to various different battery packs.
[0035] See Figure 1 and Figure 2 As shown, the battery cell module 100 of this application embodiment includes a fixing plate 110 and a plurality of battery cells 120. Figure 1 The middle section contains two sets of 100 battery cell modules.
[0036] The fixing plate 110 is provided with at least two rows of slots 111 on both sides opposite to each other along the first direction. The slots 111 are arranged along the second direction. Each slot 111 includes a plurality of fixing slots 1111 arranged along the third direction. Each fixing slot 1111 can be configured to extend along the second direction. The fixing plate 110 is configured to be parallel to the bottom of the battery pack housing.
[0037] The battery cell 120 corresponds one-to-one with the fixing groove 1111. The shape of the fixing groove 1111 matches the shape of the battery cell 120, and the side wall of the battery cell 120 is at least partially connected to the groove wall of the fixing groove 1111, so that the extension direction of the battery cell 120 is consistent with the extension direction of the fixing groove 1111.
[0038] The first direction, the second direction, and the third direction are all perpendicular to each other. Figure 1 The Z-direction is the first direction, the Y-direction is the second direction, and the X-direction is the third direction.
[0039] For example, when a battery pack is used in a vehicle, it is usually placed on the vehicle floor. In order not to affect the distance between the vehicle floor and the ground and to ensure the driving safety of the vehicle, the thickness of the battery pack along the third direction is greatly limited. In addition, the battery pack also needs to be equipped with explosion-proof valves and other devices in the third direction. This results in the limited length of the battery cell 120 in the third direction, which cannot be flexibly adjusted according to the capacity requirements of the battery cell 120.
[0040] In this embodiment, the fixing plate 110 fixes multiple battery cells 120 in preset positions through the fixing slots 1111. For battery cells 120 with different lengths due to capacity requirements, it is only necessary to change the length of the fixing slots 1111 along the second direction to match the battery cells 120 of different lengths. Therefore, the change in the length of the battery cells 120 only affects the length of the battery cell module 100 in the second direction. When it is necessary to increase the number of battery cells 120, the slot groups 111 and the number of battery cells 120 in each slot group 111 can be increased. Increasing the slot groups 111 will cause the length of the battery cell module 100 to increase in the second direction, and increasing the number of battery cells 120 in each slot group 111 will cause the length of the battery cell module 100 to increase in the third direction. In this way, adjusting either the number or length of the battery cells 120 will only affect the length of the battery pack in the second and third directions, without causing a change in the thickness of the battery pack in the first direction. Therefore, the length and number of the battery cells 120 can be flexibly adjusted according to the different usage requirements of the battery pack and the capacity requirements of the battery cells 120. This is beneficial to improving the flexibility of the battery cell 120 settings within the battery pack, expanding the applicability of the battery pack, and improving the space utilization rate of the battery pack.
[0041] Furthermore, the battery cell module 100 provided in this application embodiment can fix two layers of battery cells 120 along the first direction with only one fixing plate 110, which is beneficial to further reduce the thickness of the battery cell module 100 in the first direction and save the space occupied by the battery pack in the first direction.
[0042] See also some of the possible implementation methods. Figure 1 and Figure 2As shown, the battery cell 120 in this embodiment is cylindrical, and the fixing groove 1111 is an arc-shaped groove. The arc-shaped groove is coaxially arranged with the battery cell 120. The cylindrical battery cell 120 has a larger heat dissipation area, which is beneficial to improving the heat dissipation efficiency of the battery cell module 100. When the cylindrical battery cell 120 is placed on the fixing plate 110 without being fixed, it is easy to roll relative to the fixing plate 110. Therefore, the fixing groove 1111 is set as an arc-shaped groove, and the arc-shaped groove has the same radius of curvature as the battery cell 120. In this way, it can be ensured that the battery cell 120 is stably placed in the fixing groove 1111, which is beneficial to improving the stability of the connection between the battery cell 120 and the fixing plate 110 and improving the assembly efficiency of the battery cell module 100.
[0043] In some embodiments, the fixing grooves 1111 located on opposite sides of the fixing plate 110 along the first direction are staggered along the third direction. This can ensure the uniformity of the thickness of the fixing plate 110. For example, when the battery cell 120 is cylindrical, the fixing plate 110 as a whole can be wavy, thus presenting a plurality of fixing grooves 1111 staggered along the third direction. Of course, the specific shape of the fixing plate 110 is not limited in this embodiment and can be adjusted according to the actual shape of the fixing grooves 1111.
[0044] See also some of the possible implementation methods. Figures 1 to 3 As shown, the embodiment of this application also includes a support member 130, which is disposed between the side wall of the battery cell 120 and the fixing groove 1111, so that there is a gap between the side wall of the battery cell 120 and the fixing groove 1111.
[0045] It is understandable that the side wall of the battery cell 120 needs to be fixedly connected to the fixing groove 1111 with structural adhesive. Therefore, when assembling the battery cell module 100, a support member 130 needs to be set between the side wall of the battery cell 120 and the fixing groove 1111. This allows space to be left between the side wall of the battery cell 120 and the groove wall of the fixing groove 1111 for filling with structural adhesive, which helps to improve assembly efficiency. At the same time, it ensures that the thickness of the structural adhesive between the side wall of each battery cell 120 and the fixing groove 1111 is consistent, avoiding it being too thick or too thin, thereby improving the stability of the connection between the battery cell 120 and the fixing plate 110.
[0046] See also some of the possible implementation methods. Figures 1 to 3 As shown, the support member 130 in this embodiment includes a first support member 131 and a second support member 132.
[0047] The first support member 131 and the second support member 132 are respectively fixed at both ends of the fixing groove 1111 along the second direction. The first support member 131 and the second support member 132 are both connected to the side wall of the battery cell 120. In this way, the first support member 131, the second support member 132, the battery cell 120 and the fixing groove 1111 can jointly define a fixing space, which is used to fill structural adhesive.
[0048] In practical implementation, the shapes of the first support member 131 and the second support member 132 are matched with the fixing groove 1111 and the battery cell 120. After the side wall of the battery cell 120 is connected to the first support member 131 and the second support member 132, structural adhesive can be directly injected into the fixing space from the fixing plate 110 along the third direction, thereby completing the fixing of a groove group 111 and the battery cell 120 at one time, which is beneficial to improving the assembly efficiency of the battery cell module 100. The first support member 131 and the second support member 132 are set at both ends of the fixing groove 1111 along the second direction, which can also prevent the structural adhesive from flowing out of the fixing space, which is beneficial to ensuring the stability of the connection between the battery cell 120 and the fixing groove 1111, thereby ensuring that the battery pack can operate safely and stably.
[0049] The specific type of structural adhesive used in this embodiment is not limited, as long as it can stably connect the battery cell 120 and the fixing groove 1111. For example, polyurethane structural adhesive is used. The first support member 131 and the second support member 132 can be glued to the fixing plate 110 with acrylic adhesive to ensure the stability of the connection between the first support member 131 and the second support member 132 and the fixing plate 110, and to ensure the proper functioning of the structural adhesive by the first support member 131 and the second support member 132.
[0050] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, the fixing groove 1111 of this application embodiment has two rows along the second direction. The end of the battery cell 120 along the second direction has a tab 121, and the two rows of battery cells 120 located on the same side of the fixing plate 110 have one end of the tab 121 arranged opposite to each other.
[0051] In practical implementation, assembling the cell module 100 requires first fixing the cell 120 onto the fixing plate 110 before processing the tab 121 and welding the tab 121 onto the cell 120. Therefore, two rows of cells 120 are arranged along the second direction in a cell module 100, and the ends of the two rows of cells 120 without tabs 121 are arranged opposite each other. This allows all cells 120 in the cell module 100 to have their tabs 121 facing outwards, thus enabling the tabs 121 to be quickly welded onto the cell 120 or processed, which helps improve the assembly efficiency of the cell module 100 and leaves sufficient space for processing the tabs 121.
[0052] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, the embodiment of this application also includes a liquid cooling plate 140; the liquid cooling plate 140 is located between two rows of battery cells 120 along the second direction, and the end of the battery cell 120 away from the tab 121 is connected to the liquid cooling plate 140.
[0053] Furthermore, there can be two liquid cooling plates 140, which are respectively disposed on opposite sides of the fixing plate 110 along the first direction. Alternatively, there can be one liquid cooling plate 140, which penetrates the fixing plate 110 along the third direction, so that the battery cells 120 located on opposite sides of the fixing plate 110 can simultaneously contact the same liquid cooling plate 140. Of course, the specific cooperation method between the liquid cooling plate 140 and the fixing plate 110 is not limited in this embodiment, as long as it can ensure that all battery cells 120 in the battery cell module 100 can contact the liquid cooling plate 140 for heat dissipation. The battery cells 120 and the liquid cooling plate 140 can be fixed together with thermally conductive adhesive or thermally conductive structural adhesive. Of course, the specific fixing method is not limited in this embodiment, as long as it does not affect the heat exchange between the battery cells 120 and the liquid cooling plate 140. This can further limit the movement of the battery cells 120 in the third direction, which is beneficial to ensuring the stability of the battery cells 120.
[0054] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, the embodiment of this application also includes an insulating plate 150, which is connected to one end of the battery cell 120 where the tab 121 is provided.
[0055] In some embodiments, a battery pack typically requires multiple cell modules 100. An insulating plate 150 is provided between the cells 120 of adjacent cell modules 100 to ensure a certain distance is maintained between the cells 120. The insulating plate 150 also acts as a buffer, preventing collisions between the cell modules 100 when the battery pack experiences significant shaking, thus improving battery pack safety. The connection method between the insulating plate 150 and the cell 120 is not limited in this embodiment. For example, the insulating plate 150 can be connected to the end of the cell 120 using acrylic adhesive.
[0056] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, the fixing plate 110 in this embodiment is at least one of steel and aluminum, which can ensure the structural strength of the fixing plate 110, improve the stability of the cell 120 fixing, and ensure the safe and stable operation of the battery pack.
[0057] In addition, at least one of the first support member 131, the second support member 132 and the insulating plate 150 is a plastic part, which has insulating properties. The first support member 131 and the second support member 132 can ensure the insulation between the battery cells 120 located between the two sides of the fixing plate 110, and the insulating plate 150 can ensure the insulation between the battery cells 120 of two adjacent battery cell modules 100.
[0058] See Figure 1As shown in the embodiment of this application, a battery pack is also provided, including at least one of the above-mentioned cell modules 100.
[0059] The structure and working principle of the components have been described in detail in the above embodiments, and will not be repeated here.
[0060] In this embodiment of the application, by setting the above-mentioned cell module 100, the length and number of cells 120 can be adjusted without changing the thickness of the battery pack along a third direction, which is beneficial to make the battery pack adapt to more needs and improve the applicability of the battery pack.
[0061] See also some of the possible implementation methods. Figure 1 and Figure 2 As shown, the embodiment of this application includes a coolant supply device 10; there are at least two battery cell modules 100, which are spaced apart along a second direction; the liquid cooling plate 140 of each battery cell module 100 is connected to the coolant supply device 10.
[0062] In practice, multiple cell modules 100 are configured, and a certain gap is maintained between the insulating plates 150 of two adjacent cell modules 100 to ensure insulation between the cells 120. At the same time, the liquid cooling plates 140 in each cell module 100 can be connected to the same coolant supply device 10, thereby enabling multiple liquid cooling plates 140 to cool simultaneously, ensuring the uniformity of temperature inside the battery pack, and thus ensuring the safe and stable operation of the battery pack.
[0063] In summary, the battery cell module 100 and battery pack provided in this application embodiment have multiple battery cell modules 100 spaced apart along a second direction in the battery pack. Each battery cell module 100 includes a fixing plate 110 and multiple battery cells 120. The fixing plate 110 has at least two slot groups 111 arranged along the second direction on both sides along the first direction. Each slot group 111 has multiple fixing slots 1111 arranged along a third direction. The sidewalls of the multiple battery cells 120 are connected to the fixing slots 1111 one by one. Both the fixing slots 1111 and the battery cells 120 extend along the second direction. In this way, when the length of the cell 120 needs to be adjusted or the number of modules needs to be adjusted, the length of the cell module 100 along the second direction will change. When the number of cells 120 in each module is adjusted, the length of the cell module 100 along the third direction will change. Therefore, neither adjusting the length nor the number of cells 120 will affect the overall thickness of the battery pack along the first direction, thus giving the cells 120 more room for adjustment. This is beneficial for flexibly adjusting the length and number of cells 120 according to different requirements for the battery pack and the capacity of cells 120, thereby expanding the applicability of the battery pack.
