[0044] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0045] As Figures 1 to 16 shown, the CCS component 10 of the embodiment of the present invention includes a bracket 1, a busbar 2 and a pressure strip 3. The bracket 1 is provided with a first connecting part 11, and the busbar 2 is connected to the first connecting part 11. The pressure strip 3 is disposed on at least one side of the first connecting part 11 in its width direction. At least one of the bracket 1 and the busbar 2 is connected to the pressure strip 3.

[0046] When the CCS component 10 of the embodiment of the present invention is assembled with the battery cell 20, the busbar 2 is electrically connected to the terminal 201 of the battery cell 20, and the pressure strip 3 is connected to the top cover 202 of the battery cell 20, which not only realizes the series connection and parallel connection of multiple battery cells 20, but also realizes the connection of the pressure strip 3 with multiple battery cells 20. Since the pressure strip 3 is connected to at least one of the bracket 1 and the busbar 2, the pressure strip 3 is integrated into the CCS component 10. On the one hand, the number of components of the battery module 100 can be reduced. On the other hand, the operation of separately connecting the pressure strip 3 to the battery cell 20 is omitted, and the assembly efficiency of the battery module 100 is improved.

[0047] In some embodiments, such as Figure 3 , Figure 4 , Figure 8 , Figure 12 and Figure 13As shown, the bracket 1 is provided with a second connecting portion 12, and the second connecting portion 12 is disposed on at least one side of the first connecting portion 11 in the width direction of the pressure strip 3. The pressure strip 3 and the second connecting portion 12 are stacked, and the pressure strip 3 is connected to the second connecting portion 12.

[0048] Among them, the second connecting portion 12 is disposed on at least one side of the first connecting portion 11 in the width direction of the pressure strip 3, which can be understood as: the second connecting portion 12 is disposed on both sides of the first connecting portion 11 in the width direction of the pressure strip 3, or the second connecting portion 12 is disposed on one side of the first connecting portion 11 in the width direction of the pressure strip 3.

[0049] By providing the second connecting portion 12 on the bracket 1 and stacking the second connecting portion 12 with the pressure strip 3, the connection area between the pressure strip 3 and the bracket 1 can be increased, the connection stability between the pressure strip 3 and the bracket 1 can be improved, and thus the reliability of the CCS assembly 10 can be improved.

[0050] Optionally, the second connecting portion 12 is in the shape of a sheet, and the width of the second connecting portion 12 is greater than or equal to the width of the second connecting portion 12.

[0051] By setting the second connecting portion 12 as a sheet and the width of the second connecting portion 12 being greater than or equal to the width of the second connecting portion 12, it is beneficial to further improve the connection stability between the pressure strip 3 and the bracket 1 and improve the reliability of the CCS assembly 10.

[0052] Optionally, as Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 12 shown, the pressure strip 3 and the bus bar 2 are respectively disposed on both sides of the bracket 1 in the thickness direction of the pressure strip 3.

[0053] For example, as Figure 2 、 Figure 5 and Figure 12 shown, the thickness direction of the pressure strip 3 is consistent with the up and down direction, the pressure strip 3 is disposed on the lower side of the bracket 1, and the bus bar 2 is disposed on the upper side of the bracket 1. The lower surface of the pressure strip 3 is used to connect to the top cover 202 of the battery cell 20.

[0054] The pressure strip 3 and the bus bar 2 are respectively arranged on both sides of the bracket 1, which not only facilitates the electrical connection between the bus bar 2 and the pole 201 of the battery cell 20, but also facilitates the direct connection between the pressure strip 3 and the top cover 202 of the battery cell 20, improving the stiffness of the battery module 100.

[0055] The bracket 1 is an insulating bracket, and the pressure strip 3 is a metal pressure strip. Among them, the bracket 1 being an insulating bracket means that: the material of the bracket 1 is an insulating material; or, the surface of the bracket 1 is provided with an insulating layer. For example, the bracket 1 is a plastic bracket.

[0056] By setting the pressing strip 3 as a metal pressing strip, the structural strength of the pressing strip 3 can be improved. On the one hand, the overall stiffness of the CCS component 10 can be increased; on the other hand, when the pressing strip 3 is connected to the battery cell 20, the overall stiffness of the battery module 100 can be increased.

[0057] It can be understood that setting the pressing strip 3 as a metal pressing strip results in the pressing strip 3 having certain electrical conductivity, and electrical insulation needs to be carried out between the pressing strip 3 and the bus bar 2. By arranging the pressing strip 3 and the bus bar 2 on both sides of the bracket 1 in the thickness direction of the pressing strip 3, the insulating bracket can be used to separate the pressing strip 3 and the bus bar 2, thereby achieving electrical insulation between the pressing strip 3 and the bus bar 2. Thus, there is no need to additionally provide other insulating components between the pressing strip 3 and the bus bar 2 to achieve electrical insulation between the pressing strip 3 and the bus bar 2, which is beneficial to reducing the number of components of the CCS component 10 and improving the assembly efficiency of the CCS component 10.

[0058] Optionally, the pressing strip 3 is bonded to the second connecting portion 12.

[0059] For example, the pressing strip 3 and the second connecting portion 12 are bonded by structural adhesive or double-sided adhesive.

[0060] In some other embodiments, the pressing strip 3 and the second connecting portion 12 can also be thermally riveted.

[0061] For example, thermal riveting posts are provided on the second connecting portion 12, and riveting holes are provided on the pressing strip 3, and the thermal riveting posts pass through the riveting holes and are thermally riveted and welded.

[0062] Optionally, as Figure 5 , Figure 5 , Figure 10 and Figure 11 shown, the second connecting portion 12 has a cavity 121, and the pressing strip 3 is arranged in the cavity 121. Among them, the pressing strip 3 can be connected to the cavity wall of the cavity 121; the pressing strip 3 can also not be connected to the cavity wall of the cavity 121, and only the cavity wall of the cavity 121 is used to limit the pressing strip 3 to achieve the fixation of the pressing strip 3.

[0063] By providing the cavity 121 in the second connecting portion 12 and arranging the pressing strip 3 in the cavity 121, the pressing strip 3 can be more reliably combined with the bracket 1, improving the overall stiffness of the CCS component 10, so that when the pressing strip 3 is connected to the top cover 202 of the battery cell 10, the overall stiffness of the battery module 100 is further improved. In addition, when the pressing strip 3 is a metal pressing strip and the bracket 1 is an insulating bracket, the cavity wall of the cavity 121 can be used to wrap the pressing strip 3, which can more effectively separate the pressing strip 3 and the bus bar 2 and improve the insulation performance between the pressing strip 3 and the bus bar 2.

[0064] Optionally, as Figure 5 , Figure 7 , Figure 9 andFigure 10 As shown, the cavity 121 has a first cavity wall 1211 and a second cavity wall 1212 that are oppositely arranged along the thickness direction of the bead 3, and the first cavity wall 1211 is provided with a hollowed-out portion 1213.

[0065] For example, the first cavity wall 1211 is disposed on the upper side of the second cavity wall 1212, and the first cavity wall 1211 is provided with a plurality of hollowed-out portions 1213. The provision of the hollowed-out portions 1213 can expose the lower surface of the bead 3, so as to connect the lower surface of the bead 3 to the top cover 202 of the battery cell 20.

[0066] By providing the hollowed-out portions 1213 on the first cavity wall 1211, the bead 3 can be directly connected to the top cover 202 of the battery cell 20, improving the overall stiffness of the battery module 100.

[0067] As Figure 6 and Figure 11 shown, the second connecting portion 12 includes a first coating layer 1214 and a second coating layer 1215. The first coating layer 1214 and the second coating layer 1215 are stacked along the thickness direction of the bead 3, and the first coating layer 1214 is connected to the second coating layer 1215. A cavity 121 is formed between the first coating layer 1214 and the second coating layer 1215. Among them, the first coating layer 1214 forms the first cavity wall 1211, and the second coating layer 1214 forms the second cavity wall 1212.

[0068] Optionally, the second coating layer 1215 and the first connecting portion 11 can be integrally injection-molded, and the second coating layer 1215 and the first connecting portion 11 can also be vacuum-formed; the first coating layer 1214 is injection-molded or vacuum-formed. The first coating layer 1214 and the second coating layer 1215 are bonded or thermally riveted.

[0069] For example, the bracket 1 includes a tray and a connecting piece. Both the first coating layer 1214 and the first connecting portion 11 are disposed on the tray, and the connecting piece forms the first coating layer 1214. When manufacturing the CCS assembly 10, first, the tray, the connecting piece, and the bead 3 are respectively manufactured; then, the bead 3 is clamped between the tray and the connecting piece, and the connecting piece is connected to the tray, so as to place the bead 3 in the cavity 121 formed by the first coating layer 1214 and the second coating layer 1215.

[0070] Optionally, as Figure 11 shown, the bracket 1 is an injection-molded part, the bead 3 is a metal bead, and the bracket 1, the bus bar 2, and the bead 3 are integrally injection-molded. That is, the first coating layer 1214 and the second coating layer 1215 are integrally injection-molded. A part of the bus bar 2 and the bead 3 are both covered inside the bracket 1.

[0071] Optionally, as Figure 12As shown, the number of busbars 2 is multiple, and the multiple busbars 2 form multiple busbar groups. The multiple busbar groups are arranged at intervals in the width direction of the pressing strip 3, and the multiple busbars 2 in the same busbar group are arranged at intervals in the length direction of the pressing strip 3. The busbar 2 includes a busbar body 21 and a connecting arm 22. The busbar body 21 is connected to the first connecting portion 11, and the connecting arm 22 is provided on at least one side of the busbar body 21 in the width direction of the pressing strip 3. The connecting arm 22 is stacked with the pressing strip 3, and the connecting arm 22 is connected to the second connecting portion 12. Among them, the busbar body 21 is used for electrically connecting with the pole 201 of the battery cell 20; the connecting arm 22 and the second connecting portion 12 can be bonded or thermally riveted.

[0072] For example, the width direction of the pressing strip 3 is the same as the left-right direction, and the length direction of the pressing strip 3 is the same as the front-back direction. As Figure 12 shown, the multiple busbars 2 form four busbar groups. The four busbar groups are arranged at intervals in the left-right direction, and the multiple busbars 2 in the same busbar group are arranged at intervals in the front-back direction. In the left-right direction, the connecting arm 22 and the pressing strip 3 are arranged on the same side of the busbar body 21. The connecting arm 22 is arranged on the upper side of the second connecting portion 12, and the connecting arm 22 is connected to the second connecting portion 12. The multiple busbars 2 in the same busbar group are all connected to the same second connecting portion 12, so that the multiple busbars 2 in the same busbar group are all connected to the same pressing strip 3.

[0073] By designing the busbar 2 as above, the multiple busbars 2 can be connected into a whole by using the pressing strip 3, so that when the pressing strip 3 is connected to the top cover 202 of the battery cell 20, the stiffness of the entire battery module 100 can be improved.

[0074] Optionally, the bracket 1 is an insulating bracket, and the second connecting portion 12 is arranged between the connecting arm 22 and the pressing strip 3.

[0075] Thus, the connecting arm 22 and the pressing strip 3 can be separated by using the bracket 1 to realize insulation between the busbar 2 and the pressing strip 3. It is not necessary to additionally provide other insulating components between the connecting arm 22 and the pressing strip 3, which is beneficial to reducing the number of components of the CCS assembly 10 and improving the assembly efficiency of the CCS assembly 10.

[0076] Optionally, the pressing strip 3 is arranged between the busbar bodies 21 of two adjacent busbar groups, and the multiple connecting arms 22 in the two adjacent busbar groups are connected to the same second connecting portion 12.

[0077] For example, as Figure 13As shown, in two adjacent busbar groups, the busbar 2 in one of the busbar groups is the first busbar 23, and the busbar 2 in the other busbar group is the second busbar 24. The first busbar 23 is arranged on the left side of the second busbar 24. The second connecting part 12 is arranged between the busbar plate body 21 of the first busbar 23 and the busbar plate body 21 of the second busbar 24 in the left-right direction. The connecting arm 22 of the first busbar 23 is the first connecting arm 231, and the connecting arm 22 of the second busbar 24 is the second connecting arm 241. Both the first connecting arm 231 and the second connecting arm 241 are connected to the second connecting part 12.

[0078] Thus, the strip 3 can be used to connect multiple busbars 2 in two busbar groups into a whole. Therefore, more busbars 2 can be connected into a whole by the strip 3, so that when the strip 3 is connected to the top cover 202 of the battery cell 20, the stiffness of the entire battery module 100 is further improved.

[0079] Optionally, the strip 3 includes a fixing part 32 and a blocking part 33. The blocking part 33 and the connecting arm 22 are both arranged on the same side of the fixing part 32 in the thickness direction of the strip 3. The blocking part 33 is arranged between two adjacent connecting arms 22 in the width direction of the strip 3.

[0080] For example, both the blocking part 33 and the connecting arm 22 are arranged on the long side of the fixing part 32. The blocking part 33 is arranged between the first connecting arm 231 and the second connecting arm 241 in the left-right direction.

[0081] Thus, the blocking part 33 can be used to separate two adjacent connecting arms 22, avoiding contact between two adjacent busbars 2 in the width direction of the strip 2, which may cause a short circuit problem of the battery cell 20, and is beneficial to improving the safety of the battery module 100.

[0082] Optionally, as Figure 12 and Figure 13 shown, the blocking part 33 is in a long strip shape extending along the length direction of the strip 3.

[0083] In some embodiments, as Figures 14 to 16 shown, the bracket 1 and the strip 3 are integrally formed.

[0084] For example, the bracket 1 and the strip 3 are integrally injection molded or integrally thermoformed.

[0085] By integrally forming the bracket 1 and the strip 3, the number of components of the CCS component 10 can be further reduced, and the assembly efficiency and manufacturing cost of the CCS component 10 can be improved.

[0086] Optionally, as Figure 14As shown, the caulking strip 3 is provided with weight-reducing grooves 31 and / or weight-reducing holes. Among them, the caulking strip 3 being provided with weight-reducing grooves 31 and / or weight-reducing holes can be understood as: the caulking strip 3 is provided with weight-reducing grooves 31 and weight-reducing holes; or, the caulking strip 3 is provided with weight-reducing grooves 31 or weight-reducing holes

[0087] For example, as Figure 14 , the caulking strip 3 is provided with a plurality of weight-reducing grooves 31, and the plurality of weight-reducing grooves 31 are arranged in a matrix form.

[0088] By providing weight-reducing grooves 31 and / or weight-reducing holes in the caulking strip 3, it is beneficial to reduce the cost and weight of the CCS component 10.

[0089] The CCS component 10 further includes a circuit board, and the circuit board is electrically connected to the busbar 2 to realize the acquisition of the temperature and voltage of the battery cells 20. Among them, the circuit board can be an FPC (Flexible Printed Circuit).

[0090] The battery module 100 of the embodiment of the present invention includes a CCS component 10 and a plurality of battery cells 20. The CCS component 10 is the CCS component 10 described in any of the above embodiments. The battery cell 20 includes a pole column 201 and a top cover 202. The busbar 2 is electrically connected to the pole column 201, and the caulking strip 3 is connected to the top cover 202.
