[0001] This application relates to the field of battery technology, specifically to a battery module and vehicle with a pressure strip. Background Technology

[0002] With the rapid development of new energy vehicles, the current assembly methods for power battery system cells on the market are mainly modules or CTP structures. CTP battery modules have been widely adopted and accepted by the market. However, most CTP structures use structural adhesive to bond the cells and frames together to ensure the overall structural strength of the battery module. This design does not allow for the removability of the cells. If a cell in the battery module malfunctions, the cell to be replaced cannot be replaced, resulting in material waste and significantly increasing the after-sales maintenance costs of the battery module. Utility Model Content

[0003] In view of this, this application provides a battery module with a pressure strip, which at least solves the problem of high after-sales maintenance costs caused by the inability to replace the battery cells within the battery module.

[0030] This application provides a battery module with a pressure strip, which at least solves the problem of high after-sales maintenance costs caused by the inability to replace battery cells within the battery module. This application also provides a vehicle including the aforementioned battery module with the pressure strip.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] like Figures 1 to 6As shown, this application embodiment provides a battery module with a pressure strip. The battery module is used in electrical equipment to supply power to the equipment, which can be a vehicle, especially a new energy vehicle. The battery module mainly includes a frame 1, a cell assembly 2, and a pressure strip 3. The cell assembly 2 includes at least a plurality of stacked cells 21, and the stacked cells 21 are electrically connected to each other. The cell assembly 2 is located within the frame 1, that is, the frame 1 provides space for the cell assembly 2. The pressure strip 3 includes a pressing part 31 that presses the cell assembly 2 and a connecting part 32 that is detachably connected to the frame 1. The pressing part 31 presses the cells 21 in the height direction of the cell assembly 2, and the connecting part 32 is connected to the frame 1. The pressing part 31 and the connecting part 32 cooperate to fix the cell assembly 2, so as to conveniently and securely fix the cell assembly 2 within the frame 1. At least two pressing parts 31 are provided to press the cells located on both sides of the connecting part 32 respectively. Group 2, generally speaking, the frame 1 has a plurality of battery cell groups 2 arranged sequentially in the width direction of the battery cell group 2. By providing at least two pressing parts 31 to press the battery cell groups 2 located on both sides of the connecting part 32 respectively, a pressing strip 3 can press and fix two adjacent battery cell groups 2, thereby improving the pressing efficiency of the pressing strip 3 on the battery cell groups 2. Furthermore, based on the connection between the connecting part 32 and the frame 1, the pressing part 31 is further connected to the battery cell group 2 through a detachable connector 4. This arrangement can further improve the stability of the connection between the pressing strip 3 and the battery cell group 2, as well as between the pressing strip 3 and the frame 1, thereby improving the stability of the connection between the pressing strip 3 and the battery cell group 2, and thus improving the stability of the fixation between the battery cell group 2 and the frame 1.

[0033] It should be noted that the detachable connection method between the pressing part 31 and the battery cell assembly 2 and the detachable connection method between the connecting part 32 and the frame 1 are not limited here. The detachable connection can be one or a combination of bolt connection, snap-fit ​​connection, magnetic connection, etc.

[0034] It should also be noted that the connection position between the connecting part 32 and the frame 1 is not limited here. The connecting part 32 can be connected to the beam of the frame 1, or it can be connected to the side wall or bottom wall of the frame 1.

[0035] It should also be noted that the height direction of cell pack 2 refers to... Figure 2 The direction indicated by the double-headed arrow Z.

[0036] The battery module with the above structure uses the pressing part 31 of the pressing strip 3 to press the cell group 2, and the pressing part 32 of the pressing strip 3 to connect with the frame 1, thereby fixing the cell group 2 in the height direction of the cell group 2. Furthermore, the pressing part 31 of the pressing strip 3 is connected to the cell group 2 via a detachable connector 4, which further improves the stability of the connection between the cell group 2 and the frame 1. With this configuration, when a cell 21 in the cell group 21 malfunctions, the pressing strip 3 can be disassembled to release its restriction on the cell group 2, and then the corresponding cell 21 can be replaced. This ensures the overall structural stability of the battery module while facilitating the replacement of the cells 21 in the cell group 21, saving materials and significantly reducing after-sales maintenance costs.

[0037] In some embodiments, please refer to Figures 2 to 4 The frame 1 includes first support beams 11 located on both sides of the battery cell assembly 2 in the width direction. Specifically, multiple first support beams 11 are spaced apart in the width direction of the battery cell assembly 2. Adjacent first support beams 11 limit the installation position of the battery cell assembly 2 in the width direction of the battery cell assembly 2. Multiple battery cell assemblies 2 are provided and are respectively arranged in the intervals between adjacent first support beams 11. Furthermore, the connecting part 32 is connected to the first support beam 11 to realize the fixation between the connecting part 32 and the frame 1. This arrangement can improve the stability of the connection between the pressure strip 3 and the frame 1. In addition, in the above embodiment, the pressing part 31 is detachably connected to the battery cell assembly 2, that is, the pressure strip 3 and the battery cell assembly 2 are connected together, which can more firmly realize the connection between the battery cell assembly 2, the pressure strip 3 and the frame 1.

[0038] It should be noted that the width direction of cell pack 2 refers to... Figure 2 The direction indicated by the double-headed arrow X.

[0039] In some embodiments, please refer to Figures 2 to 4 The connecting part 32 extends into the gap between adjacent cell groups 2 and connects with the first support beam 11. This arrangement allows the pressure strip 3 to limit the movement of the cell group 2 in the width direction, and also ensures a tight connection between the connecting part 32 and the first support beam 11, improving the connection stability and thus enhancing the structural strength of the connection between the cell group 2 and the frame 1. The connecting part 32 is connected to the first support beam 11 by bolts 5, thereby improving the structural strength of the connection between the bolts 5 and the first support beam 11. Furthermore, the bolts 5 penetrate the connecting part 32, further enhancing the connection strength between the connecting part 32 and the first support beam 11, and also improving the bending resistance of the connecting part 32, thus improving the overall structural stability of the battery module. Of course, the bolts 5 penetrating the connecting part 32 also facilitate the connection between the connecting part 32 and the first support beam 11, thereby improving the convenience of the connection.

[0040] In some embodiments, please refer to Figure 1 and Figure 2 The pressure strip 3 is installed along the entire length of the cell assembly 2. This means that the pressure strip 3 covers all parts of the cell assembly 2 along its length. This arrangement enhances the pressure effect of the pressure strip 3 on the cell assembly 2, thereby improving the stability of the connection between the cell assembly 2 and the frame 1. Furthermore, multiple bolts 5 are spaced apart along the length of the cell assembly 2. The presence of multiple bolts 5 ensures the connection between the pressure strip 3 and the first support beam 11 at various points along the length of the cell assembly 2, further enhancing the pressure effect of the pressure strip 3 on the cell assembly 2 and thus further improving the stability of the connection between the cell assembly 2 and the frame 1.

[0041] It should be noted that the length direction of cell pack 2 refers to... Figure 2 The direction indicated by the double-headed arrow Y.

[0042] In addition, the pressure strip 3 can also be set in a non-continuous manner. For example, multiple pressure strips 3 can be spliced ​​together along the length of the battery cell group 2; or multiple pressure strips 3 can be set at intervals along the length of the battery cell group 2.

[0043] In some embodiments, please refer to Figure 3 and Figure 4 The pressure strip 3 and the first support beam 11 are hollow frame structures. This design can reduce the weight of the pressure strip 3 and the first support beam 11 while ensuring the structural strength of the battery module. In turn, it can reduce the overall weight of the battery module while ensuring the structural strength of the battery module, thereby achieving the lightweight development of the battery module, reducing the weight of the vehicle equipped with the battery module, and ultimately improving the vehicle's driving range.

[0044] Furthermore, in the height direction of the battery cell assembly 2, the height of the connecting part 32 is at least half the height of the battery cell assembly 2. That is, when the connecting part 32 and the first support beam 11 are connected together by bolts 5, the height of the connecting part 32 is half the height of the battery cell assembly 2, and the height of the first support beam 11 is the other half of the height of the battery cell assembly 2. This can improve the limiting effect of the connecting part 32 and the first support beam 11 on the battery cell assembly 2, further improve the stability of limiting the battery cell assembly 2, and thus improve the fixing effect of the frame 1 on the battery cell assembly 2.

[0045] In some embodiments, please refer to Figure 5The cross-section of the pressure strip 3 is T-shaped. That is, a pressure strip 3 has two pressing portions 31 to form two horizontal portions of the T-shape, and a connecting portion 32 located in the middle to form the vertical portion of the T-shape. This arrangement allows one pressure strip 3 to simultaneously press the battery cells 2 located on both sides of the pressure strip 3 in the width direction of the battery cell assembly 2, making the layout of the battery cell assembly 2 and the pressure strip 3 more compact, improving the tightness of the pressure strip 3 pressing the battery cell assembly 2, and thus improving the overall stability of the battery module.

[0046] Here, the cross-sectional shape of the pressure strip 3 is not limited. For example, the cross-sectional shape of the pressure strip 3 can be L-shaped, V-shaped, M-shaped, etc.

[0047] In some embodiments, please refer to Figure 2 In the height direction of the cell assembly 2, the projection of the pressure strip 3 does not coincide with the projection of the explosion-proof valve of the cell 21. That is, the pressing part 31 of the pressure strip 3 does not press against the explosion-proof valve of the cell 21. After the cell assembly 2 is assembled into the battery module and the battery module is installed in the electrical equipment, during the use of the electrical equipment, when a cell 21 in the battery module experiences thermal runaway, the thermally runaway cell 21 will eject high-temperature, high-pressure gas from the location of its explosion-proof valve, achieving directional discharge of the high-temperature, high-pressure gas and thus improving the safety of the battery module during use. In this embodiment, ensuring that the projection of the pressure strip 3 does not coincide with the projection of the explosion-proof valve of the cell 21 ensures that the high-temperature, high-pressure gas inside the cell 21 can be quickly ejected when thermal runaway occurs, avoiding obstruction of the explosion-proof valve by the pressure strip 3, thereby improving the safety of the battery module during use.

[0048] In some embodiments, please refer to Figures 2 to 4 The cell assembly 2 includes end plates 22 disposed at both ends along its length, and a pressing portion 31 connected to the end plates 22. Specifically, the pressing portion 31 is detachably connected to the end plates 22 via connectors 4. In the above embodiment, the end plates 22 abut against the second support beam 12 of the frame 1, and the pressing portion 31 is then connected to the end plates 22. The connecting portion 32, integrally formed with the pressing portion 31, is connected to the first support beam 11 of the frame 1. This further enhances the stability of the connection between the cell assembly and the frame 1, preventing the cell assembly 2 from shaking when the battery module experiences unavoidable vibrations, thus improving the structural strength of the connection between the cell assembly 2 and the frame 1. Furthermore, connecting the pressing portion 31 to the end plates 22 via connectors 4 prevents contact between the pressing portion 31 and the cell 21, thereby protecting the cell 21.

[0049] Of course, the pressing part 31 can also be connected to other positions of the cell assembly 2, for example, the pressing part 31 can be connected to the end plates 22 at both ends of the cell assembly 2 in the width direction.

[0050] For example, the connector 4 can be a bolt, which can improve the stability of the connection between the pressing part 31 and the end plate 22.

[0051] In some embodiments, please refer to Figure 1 and Figure 2 The battery cell assembly 2 includes end plates 22 disposed at both ends along its length, and foam (not shown in the figure) is disposed between adjacent battery cells 21. The frame 1 includes second support beams 12 disposed at both ends along the length of the battery cell assembly 2. The battery cell assembly 2 is placed between the two second support beams 12, that is, in the space between two adjacent first support beams 11 and two adjacent second support beams 12. The end plates 22 are in limiting contact with the second support beams 12, and the compressed foam applies a force to the end plates 22 to press against the second support beams 12, thereby limiting the battery cell assembly 2 along its length. Specifically, when placing the battery cell assembly 2 between two adjacent second support beams 12, a compressive force is applied to the battery cell assembly 2 along its length using a compression tool (not shown in the figure). Because the foam between the battery cells 21 has a certain elasticity, the compression makes the length of the battery cell assembly 2 less than its initial length. The compressed battery cell assembly 2 is then placed between the two second support beams 12. Afterwards, the compression tool is released, and the rebound force of the foam in the battery cell assembly 2 causes the end plate 22 of the battery cell assembly 2 to abut against the second support beam 12. This arrangement conveniently limits the battery cell assembly 2 along its length. Combined with the pressure strip 3 limiting the height of the battery cell assembly 2, the stability of the connection between the battery cell assembly 2 and the frame 1 is further improved, enhancing the fixing effect of the frame 1 on the battery cell 21.

[0052] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 6At least one of the end plate 22 and the second support beam 12 is provided with a limiting protrusion 121 protruding along the length direction of the cell assembly 2, and at least the other is provided with a limiting groove 221 adapted to the limiting protrusion 121. An exemplary embodiment in this case provides the following implementation: a limiting protrusion 121 is provided on the end plate 22, and a limiting groove 221 is provided on the second support beam 12; a limiting protrusion 121 is provided on the second support beam 12, and a limiting groove 221 is provided on the end plate 22; a limiting protrusion 121 is provided on the end plate 22, and a limiting groove 221 is provided on the second support beam 12, while simultaneously a limiting protrusion 121 is provided on the second support beam 12, and a limiting groove 221 is provided on the end plate 22. Here, through the aforementioned limiting protrusion 121 and limiting groove 221, after the battery cell assembly 2, which is in a compressed state, is placed between adjacent second support beams 12, the compression of the battery cell assembly 2 by the compression fixture is released. Under the action of the elastic force of the foam in the battery cell assembly 2, the limiting protrusion 121 in the end plate 22 of the battery cell assembly 2 extends into the limiting groove 221 in the second support beam 12, thereby achieving rapid positioning between the end plate 22 and the second support beam 12, improving the stability of the contact between the end plate 22 and the second support beam 12, further improving the fixing effect of the frame 1 on the battery cell assembly 2, and improving the structural stability of the frame 1 in fixing the battery cell assembly 2. Furthermore, by setting the aforementioned limiting protrusion 121 and limiting groove 221, a limiting effect can be achieved during the installation of the battery cell assembly 2 into the frame 1, thereby improving the installation efficiency of the battery cell assembly 2. In addition, by setting the aforementioned limiting protrusion 121 and limiting groove 221, the battery cell assembly 2 can be limited not only in the length direction but also in the width and / or height direction. This setting can further improve the stability of the frame 1 in fixing the battery cell assembly 2, and improve the overall stability of the battery module structure through multi-directional limiting.

[0053] Since the extrusion fixture that applies extrusion force to the battery cell assembly 2 along its length is typically a clamp, after the extruded battery cell assembly 2 is placed into the frame 1 by the clamp, the clamp needs to be removed from the frame 1. During the removal process, the clamp will interfere with the frame 1. Therefore, in some embodiments, please refer to... Figure 2 , Figure 3 and Figure 6The limiting protrusions 121 and limiting grooves 221 are spaced apart along the width of the cell assembly 2. This arrangement allows the clamping jaws of the extrusion fixture to easily hold the extruded cell assembly 2 within the frame 1 after it has been placed into the frame 1, as the gaps between the limiting protrusions 121 facilitate placement. Furthermore, it allows the clamping jaws to easily move out of the gaps between the limiting protrusions 121 after the cell assembly 2 has been placed in the frame 1. This design improves the efficiency of placing the cell assembly 2 into the frame 1 and the efficiency of removing the extrusion fixture from the frame 1, thereby increasing the assembly efficiency of the battery module.

[0054] It should be noted that the limiting protrusion 121 on the end plate 22 is correspondingly provided with the limiting groove 221 on the second support beam 12, and the limiting groove 221 on the end plate 22 is correspondingly provided with the limiting protrusion 121 on the second support beam 12.

[0055] This application provides a vehicle including the battery module described in the above embodiments. The battery includes the aforementioned battery module, with a cell assembly 2 pressed against it by a pressing portion 31 of a pressing strip 3, and connected to a frame 1 by a connecting portion 32 of the pressing strip 3. This fixes the cell assembly 2 in the height direction of the cell assembly 2. Furthermore, the pressing portion 31 of the pressing strip 3 is connected to the cell assembly 2 by a detachable connector 4, further improving the stability of the connection between the cell assembly 2 and the frame 1. With this configuration, when a cell 21 within the cell assembly 21 malfunctions, the pressing strip 3 can be disassembled to release its restriction on the cell assembly 2, and then the corresponding cell 21 can be replaced. This ensures the overall structural stability of the battery module while facilitating the replacement of the cells 21 within the cell assembly 21, saving materials and significantly reducing after-sales maintenance costs.
