[0003] Current battery module designs tend to place voltage acquisition systems on both sides of the battery module, with each side equipped with a separate acquisition board and external wiring harness for monitoring the cell's operating status. However, this increases material usage, leading to higher material costs. Furthermore, the increased material requirements and space demands result in lower battery pack volume utilization and energy density. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a battery module, comprising: multiple battery cells arranged sequentially along a first direction, each battery cell including a cell body and two tabs electrically connected to the cell body; along a second direction, the cell body having a first side and a second side disposed opposite to each other, with the two tabs located on the first side and the second side respectively; a limiting member including a first limiting member and a second limiting member, the first limiting member having a first busbar region and a lead-out region, the second limiting member having a second busbar region, the first busbar region and the second busbar region being located on the first side and the second side respectively; multiple tabs on the first side being electrically connected to the first busbar region, and multiple tabs on the second side being electrically connected to the second busbar region, so that the multiple battery cells are connected in series or in parallel through the limiting member, wherein the lead-out region is located on the second side and is electrically connected to the first busbar region; and a collection member located on the second side, with the lead-out region and the second busbar region being electrically connected to the collection member respectively.

[0006] Furthermore, there are multiple first limiting members and multiple second limiting members. The first limiting members and the second limiting members are alternately arranged in the first direction. A first limiting member or a second limiting member is provided between two adjacent battery cells. The polarities of the two tabs adjacent to the first bus region are opposite and both are connected to the first bus region between them. The polarities of the two tabs adjacent to the second bus region are opposite and both are connected to the second bus region between them, so that multiple battery cells are connected in series.

[0007] Furthermore, the first limiting member includes: a first limiting plate located between two corresponding battery cells; a first busbar located on a first side; and a lead-out tab located on a second side. The first busbar and the lead-out tab are connected to both sides of the first limiting plate. The first busbar and the lead-out tab are both set at an angle to the first limiting plate. The side of the first busbar facing away from the battery cell body forms a first busbar area, and the side of the lead-out tab facing away from the battery cell body forms a lead-out area.

[0008] Furthermore, the first busbar is parallel to the first direction, and the first limiting plate is connected between the two ends of the first busbar in the first direction.

[0009] Furthermore, the first limiting plate includes a first plate segment, a second plate segment, and a third plate segment connected in sequence. The first plate segment and the third plate segment are respectively arranged at an angle to the second plate segment. In a first direction, the first plate segment and the third plate segment are located on the same side of the second plate segment.

[0010] Furthermore, the second limiting member includes: a second limiting plate located between two corresponding battery cells; and a second busbar connected to the second limiting plate and set at an angle, the second busbar located on the second side, and the side of the second busbar facing away from the battery cell body forming a second busbar area.

[0011] Furthermore, the second busbar is parallel to the first direction, and the second limiting plate is connected between the two ends of the second busbar in the first direction.

[0012] Furthermore, the second limiting plate includes a fourth plate segment, a fifth plate segment, and a sixth plate segment connected in sequence. The fourth plate segment and the sixth plate segment are respectively arranged at an angle to the fifth plate segment. In the first direction, the fourth plate segment and the sixth plate segment are located on the same side of the fifth plate segment.

[0013] Furthermore, there is one first limiting member and one second limiting member. The multiple tabs on the first side have the same polarity and are all connected to the first busbar area. The multiple tabs on the second side have the same polarity and are all connected to the second busbar area, so that multiple cells are connected in parallel.

[0014] Furthermore, the acquisition component includes an acquisition plate and two acquisition parts electrically connected to the acquisition plate. The two acquisition parts are spaced apart along a first direction, and the lead-out area and the second convergence area are electrically connected to the two acquisition parts respectively.

[0015] According to another aspect of the present invention, the present invention provides a battery pack, including a housing and the aforementioned battery module, wherein the battery module is located inside the housing.

[0016] By applying the technical solution of this utility model, a first current-collecting area and a lead-out area are set on the first limiting member, with the first current-collecting area located on the first side and the lead-out area located on the second side. The first current-collecting area can collect current from multiple battery cells and lead the voltage of multiple battery cells on the first side A to the second side B through the lead-out area. The second limiting member is provided with a second current-collecting area for collecting current from multiple battery cells, and the second current-collecting area is located on the second side B. In this way, voltage acquisition can be achieved by setting the acquisition component only on the second side B. Compared with the prior art of setting acquisition components on both sides of the battery module, this application sets the current-collecting component only on one side of the battery module, which can not only reduce materials (eliminating the single-sided acquisition board and wiring harness, reducing the number of parts) to reduce material costs, but also reduce the battery pack volume, thereby improving the battery pack space utilization rate, thereby improving the energy density of the battery pack, and also improving assembly efficiency.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 4 As shown, an embodiment of this utility model provides a battery module, including: a plurality of battery cells 10 arranged sequentially along a first direction, each battery cell 10 including a battery cell body 11 and two tabs 12 electrically connected to the battery cell body 11; along a second direction, the battery cell body 11 has a first side A and a second side B oppositely disposed, and the two tabs 12 are respectively located on the first side A and the second side B; and a limiting member, including a first limiting member 20 and a second limiting member 30, the first limiting member 20 having a first busbar region 21 and a lead-out region 22, and the second limiting member 30 having a first limiting member 20 and a second limiting member 30. The two bus regions 31, the first bus region 21 and the second bus region 31 are located on the first side A and the second side B respectively. Multiple tabs 12 on the first side A are electrically connected to the first bus region 21, and multiple tabs 12 on the second side B are electrically connected to the second bus region 31, so that multiple battery cells 10 are connected in series or in parallel through limiting members. The lead-out region 22 is located on the second side B and is electrically connected to the first bus region 21. The acquisition member 40 is located on the second side B, and the lead-out region 22 and the second bus region 31 are electrically connected to the acquisition member 40 respectively.

[0026] In the above technical solution, by setting a first current-collecting area 21 and a lead-out area 22 on the first limiting member 20, with the first current-collecting area 21 located on the first side and the lead-out area 22 located on the second side, the first current-collecting area 21 can collect current from multiple battery cells and lead the voltage of multiple battery cells on the first side A to the second side B through the lead-out area 22. The second limiting member 30 is provided with a second current-collecting area 31 for collecting current from multiple battery cells, and the second current-collecting area 31 is located on the second side B. In this way, voltage acquisition can be achieved by setting the acquisition component only on the second side B. Compared with the prior art of setting acquisition components on both sides of the battery module, this application sets the current-collecting component only on one side of the battery module, which can not only reduce materials (eliminating the single-sided acquisition board and wiring harness, reducing the number of parts) to reduce material costs, but also reduce the battery pack volume, thereby improving the battery pack space utilization rate, thereby improving the energy density of the battery pack, and also improving assembly efficiency.

[0027] In existing technologies, series and parallel connections between battery cells typically rely on conventional busbars. Generally, the positive and negative tabs of the battery cell are soldered to busbars on both sides, and the series and parallel connections are achieved through the conduction of the busbars. These busbars increase material costs. However, in this application, by providing a first busbar region 21, a second busbar region 31, and a lead-out region 22 on the limiting member, current can be drawn on both sides of each battery cell 10 while fixing multiple battery cells 10, thus achieving series or parallel connections between multiple battery cells 10. This reduces the need for traditional busbars and lowers material costs.

[0028] Preferably, in the embodiment of this utility model, the plurality of tabs 12 on the first side A are welded to the first busbar region 21, the plurality of tabs 12 on the second side B are welded to the second busbar region 31, and the lead-out region 22 and the second busbar region 31 are respectively welded to the acquisition component 40.

[0029] like Figure 1 and Figure 2 As shown in the embodiment of this utility model, there are multiple first limiting members 20 and multiple second limiting members 30. The first limiting members 20 and the second limiting members 30 are alternately arranged in the first direction. A first limiting member 20 or a second limiting member 30 is provided between two adjacent battery cells 10. The two tabs 12 adjacent to the first bus region 21 have opposite polarities and are both connected to the first bus region 21 between them. The two tabs 12 adjacent to the second bus region 31 have opposite polarities and are both connected to the second bus region 31 between them, so that multiple battery cells 10 are connected in series.

[0030] In the above technical solution, the first limiting member 20 and the second limiting member 30 not only serve to fix and limit the battery cell 10, but also each integrates the first bus region 21 and the second bus region 31. These two regions are respectively connected to the two tabs 12 with opposite polarities, thereby realizing the series connection of multiple battery cells without the need for additional busbars. This simplifies the internal connection structure of the battery module, effectively reduces material costs, and also improves the space utilization and energy density of the battery module.

[0031] Specifically, in the embodiments of this utility model, each first limiting member 20 contains a battery cell 10, and each second limiting member 30 contains a battery cell 10.

[0032] like Figure 1 and Figure 2As shown in the embodiment of this utility model, the first limiting member 20 includes: a first limiting plate 23, located between two corresponding battery cells 10; a first busbar 24, located on the first side A; and a lead-out tab 25, located on the second side B. The first busbar 24 and the lead-out tab 25 are connected to both sides of the first limiting plate 23. The first busbar 24 and the lead-out tab 25 are both set at an angle to the first limiting plate 23. The side of the first busbar 24 facing away from the battery cell body 11 forms a first busbar area 21, and the side of the lead-out tab 25 facing away from the battery cell body 11 forms a lead-out area 22.

[0033] In the above technical solution, the first limiting plate 23 is located between two battery cells, while the first busbar 24 and the lead-out tabs 25 are respectively disposed on both sides of the first limiting plate 23. This ensures that the positive and negative tabs of the battery cells can directly contact the first busbar 24 and form an electrical connection. Furthermore, the voltage of multiple battery cells on the first side A is sequentially led to the second side B through the first busbar 24, the first limiting plate 23, and the lead-out tabs 25. Voltage acquisition can be achieved by only setting up a sampling component on the second side B. This avoids the need for independent busbars and dual-sided sampling boards in traditional solutions, reducing material usage and lowering costs. Simultaneously, it optimizes the spatial layout of the module, improving volume utilization and indirectly increasing the energy density of the battery module.

[0034] like Figure 1 and Figure 4 As shown, in an embodiment of the present invention, the first busbar 24 is parallel to the first direction, and the first limiting plate 23 is connected between the two ends of the first busbar 24 in the first direction.

[0035] In the above technical solution, the first busbar 24 is parallel to the first direction, and the first limiting plate 23 is connected between the two ends of the first busbar 24 in the first direction, forming a stable and efficient cell connection platform. In this way, the two cells 10 adjacent to the first limiting member 20 can directly establish an electrical connection with the corresponding first busbar 24.

[0036] like Figure 4 As shown in the embodiment of this utility model, the first limiting member 20 further includes a bent plate for connecting the first busbar 24 and the first limiting plate 23. The first busbar 24, the first limiting plate 23, the lead-out electrode 25 and the bent plate are integrally formed and are formed by bending the sheet metal, which facilitates processing.

[0037] like Figure 4As shown in the embodiment of this utility model, the first limiting plate 23 includes a first plate segment 231, a second plate segment 232, and a third plate segment 233 connected in sequence. The first plate segment 231 and the third plate segment 233 are respectively arranged at an angle to the second plate segment 232. In the first direction, the first plate segment 231 and the third plate segment 233 are located on the same side of the second plate segment 232. In this way, a C-shaped frame can be formed to fix the corresponding battery cell 10. The first plate segment 231 and the third plate segment 233 are respectively located on the upper and lower sides of the corresponding battery cell 10, and the second plate segment 232 is located on one side of the corresponding battery cell 10 in the first direction to limit the position of the corresponding battery cell 10.

[0038] In this application, a welding plate (first busbar 24 or second busbar 33) is led out through a C-frame, and the electrode tabs of the battery cell are welded to the welding plate. In this way, the C-frame that fixes the battery cell integrates voltage acquisition and busbar functions, eliminating the need for a dedicated busbar. This integration of voltage acquisition and busbar functions into the C-frame simplifies the design, improves assembly efficiency, reduces material costs, and simultaneously increases volume utilization and energy density.

[0039] like Figure 1 and Figure 3 As shown, in the embodiment of this utility model, the second limiting member 30 includes: a second limiting plate 32, located between two corresponding battery cells 10; and a second busbar 33, connected to the second limiting plate 32 and set at an angle, the second busbar 33 being located on the second side B, and the side of the second busbar 33 facing away from the battery cell body 11 forming a second busbar area 31.

[0040] In the above technical solution, the second limiting plate 32 and the second busbar 33 effectively fix and electrically connect the battery cell 10. The second limiting plate 32 is placed between two adjacent battery cells 10 to ensure stable positioning of the battery cell, while the second busbar 33, which is connected at an angle to it, is located on the second side B. The side of the busbar 33 away from the battery cell body 11 forms the second busbar area 31, which allows the battery cell's tabs to be directly soldered to the second busbar 33 to form a series circuit. This simplifies the structure and assembly process of the battery module, thereby improving the overall energy density and assembly efficiency.

[0041] like Figure 2 and Figure 3 As shown, in an embodiment of the present invention, the second busbar 33 is parallel to the first direction, and the second limiting plate 32 is connected between the two ends of the second busbar 33 in the first direction.

[0042] In the above technical solution, the second busbar 33 is parallel to the first direction, and the second limiting plate 32 is connected between the two ends of the second busbar 33 in the first direction, forming a stable and efficient cell connection platform. This allows the two cells 10 adjacent to the second limiting member 30 to directly establish an electrical connection with the corresponding second busbar 33.

[0043] like Figure 3 As shown in the embodiment of this utility model, the second limiting member 30 further includes a bent plate for connecting the second busbar 33 and the second limiting plate 32. The second busbar 33, the second limiting plate 32 and the bent plate are integrally formed and are formed by bending sheet metal, which facilitates processing.

[0044] like Figure 3 As shown in the embodiment of this utility model, the second limiting plate 32 includes a fourth plate segment 321, a fifth plate segment 322, and a sixth plate segment 323 connected in sequence. The fourth plate segment 321 and the sixth plate segment 323 are respectively arranged at an angle to the fifth plate segment 322. In the first direction, the fourth plate segment 321 and the sixth plate segment 323 are located on the same side of the fifth plate segment 322. In this way, a C-shaped frame can be formed to fix the corresponding battery cell 10. The fourth plate segment 321 and the sixth plate segment 323 are respectively located on the upper and lower sides of the corresponding battery cell 10, and the fifth plate segment 322 is located on one side of the corresponding battery cell 10 in the first direction to limit the position of the corresponding battery cell 10.

[0045] In one embodiment, there is one first limiting member 20 and one second limiting member 30. The multiple tabs 12 on the first side A have the same polarity and are all connected to the first bus region 21. The multiple tabs 12 on the second side B have the same polarity and are all connected to the second bus region 31, so that multiple cells 10 are arranged in parallel.

[0046] like Figure 1 As shown in the embodiment of this utility model, the acquisition component 40 includes an acquisition plate 41 and two acquisition parts 42 electrically connected to the acquisition plate 41. The two acquisition parts 42 are arranged at intervals along a first direction, and the lead-out area 22 and the second confluence area 31 are electrically connected to the two acquisition parts 42 respectively.

[0047] In the above technical solution, the two acquisition units 42 are connected to the lead-out area 22 and the second busbar area 31 respectively, forming an efficient and simple voltage acquisition and current collection system.

[0048] like Figure 2As shown in the embodiment of this utility model, each collection unit 42 includes multiple collection nickel plates, which are spaced apart along a first direction. The multiple collection nickel plates of one of the two collection units 42 are electrically connected to multiple lead-out tabs, and the multiple collection nickel plates of the other collection unit 42 are electrically connected to multiple second busbars 33.

[0049] It should be noted that the acquisition component 40 can use existing technology, which will not be elaborated here.

[0050] like Figure 1 As shown in the embodiment of this utility model, two battery cells 10 are respectively placed inside the first limiting member 20 and the second limiting member 30, forming a whole for stacking. On the first side: the tabs of the two series-connected battery cells 10 are welded to the first busbar area 21 of the first limiting member 20, so that the voltage at this point can be guided to the other side through the first limiting member 20. At the same time, the first busbar area 21 can also serve as a busbar, replacing the busbar. On the second side: the voltage collected on the first side is welded to the collection part 42 through the lead-out area 22, and the voltage is transmitted to the wiring harness through the collection board. The tabs of the two series-connected battery cells 10 are welded to the second busbar area 31 of the second limiting member 30, so that the second busbar area 31 can also serve as a busbar, replacing the busbar. With the above structure, the busbars on both sides, as well as the collection component and wiring harness on the first side, are eliminated. The battery cells are connected in series by a C-shaped frame, and the voltage on the first side is guided to the second side. The voltage is collected only through the collection component on the second side.

[0051] An embodiment of this utility model provides a battery pack, which includes a housing and the aforementioned battery module, with the battery module located inside the housing.

[0052] Preferably, the battery module in the embodiment of this utility model can be a pouch module, and similarly, the battery pack can be a pouch battery pack.

[0053] The battery pack described above has all the advantages of the battery module described above, which will not be repeated here.

[0054] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: by setting a first current-collecting area and a lead-out area on the first limiting member, with the first current-collecting area located on the first side and the lead-out area located on the second side, the first current-collecting area can collect current from multiple battery cells and lead the voltage of multiple battery cells on the first side A to the second side B through the lead-out area. The second limiting member is provided with a second current-collecting area for collecting current from multiple battery cells, and the second current-collecting area is located on the second side B. In this way, voltage acquisition can be achieved by setting the acquisition component only on the second side B. Compared with the prior art of setting acquisition components on both sides of the battery module, this application sets the current-collecting component only on one side of the battery module, which can not only reduce materials (eliminating the single-sided acquisition board and wiring harness, reducing the number of parts) to reduce material costs, but also reduce the battery pack volume, thereby improving the battery pack space utilization rate, thereby improving the energy density of the battery pack, and also improving assembly efficiency.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
