[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the directional words such as "upper" and "lower" used generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0039] See also Figure 1 and Figure 2 The present application provides a battery cell support 1, the battery cell support 1 has a first direction and a second direction, and the battery cell support 1 includes:

[0040] A frame 11, the frame 11 is provided with a first slot group and a second slot group, the first slot group and the second slot group are arranged at intervals along the second direction, the first slot group includes a plurality of first busbar mounting slots 111, the second slot group includes a plurality of second busbar mounting slots 112, the plurality of first busbar mounting slots 111 and the plurality of second busbar mounting slots 112 are arranged in sequence along the first direction, and the plurality of first busbar mounting slots 111 and the plurality of second busbar mounting slots 112 are arranged at intervals along the second direction;

[0041] Each first busbar mounting groove 111 includes a first mounting sub-groove 1111 and a second mounting sub-groove 1112, and the first mounting sub-groove 1111 and the second mounting sub-groove 1112 at least partially overlap along the second direction;

[0042] And / or, each second busbar mounting groove 112 includes a third mounting sub-groove 1121 and a fourth mounting sub-groove 1122 , and the third mounting sub-groove 1121 and the fourth mounting sub-groove 1122 at least partially overlap along the second direction.

[0043] It should be noted that the at least partial overlap of the first mounting sub-groove 1111 and the second mounting sub-groove 1112 along the second direction includes two situations, the first being that the first mounting sub-groove 1111 and the second mounting sub-groove 1112 are staggered along the second direction, and the second being that the first mounting sub-groove 1111 and the second mounting sub-groove 1112 are aligned along the second direction, i.e., completely overlapped. Similarly, the at least partial overlap of the third mounting sub-groove 1121 and the fourth mounting sub-groove 1122 along the second direction includes two situations, the first being that the third mounting sub-groove 1121 and the fourth mounting sub-groove 1122 are staggered along the second direction, and the second being that the third mounting sub-groove 1121 and the fourth mounting sub-groove 1122 are aligned along the second direction, i.e., completely overlapped. In this embodiment, whether the first mounting sub-groove 1111 and the second mounting sub-groove 1112 or the third mounting sub-groove 1121 and the fourth mounting sub-groove 1122 are used, they are all the first situation, i.e., staggered settings.

[0044] The technical solution provided in the present application is mainly achieved by opening a plurality of first bus bar mounting grooves 111 and a plurality of second bus bar mounting grooves 112 which are spaced apart on the frame 11, and each first bus bar mounting groove 111 opens a first mounting sub-groove 1111 and a second mounting sub-groove 1112 which are staggered, and each second bus bar mounting groove 112 opens a third mounting sub-groove 1121 and a fourth mounting sub-groove 1122 which are staggered, so as to open as many mounting sub-grooves as possible in the limited space of the frame 11, thereby improving the space utilization of the battery cell holder 1 and achieving a higher density battery module installation. In detail, it is mainly through opening a plurality of first bus bar mounting grooves 111 and a plurality of second bus bar mounting grooves 112 on the frame 11, and the plurality of first bus bar mounting grooves 111 and the plurality of second bus bar mounting grooves 112 are staggeredly arranged along the second direction, so that the first bus bar mounting grooves 111 and the second bus bar mounting grooves 112 can compress the space as much as possible in the first direction, and increase the number of bus bar mounting grooves that can be opened on the frame 11; further, each first bus bar mounting groove 111 includes a first mounting sub-groove 1111 and a second mounting sub-groove 1112 that are staggered, and each second bus bar mounting groove 112 includes a third mounting sub-groove 1121 and a fourth mounting sub-groove 1122 that are staggered, so that the structures of the first bus bar mounting grooves 111 and the second bus bar mounting grooves 112 themselves are more compact, which can further improve the space utilization rate of the battery cell holder 1.

[0045] It should be noted that the first busbar mounting slots 111 arranged in a staggered manner along the second direction may be arranged in one row or in multiple rows, and correspondingly, the second busbar mounting slots 112 may be arranged in a staggered manner along the second direction in one row or in multiple rows, which is not limited here. Also, in this embodiment, the first busbar mounting slot 111 includes a first mounting sub-groove 1111 and a second mounting sub-groove 1112. In other embodiments, the first busbar mounting slot 111 may also include more mounting sub-grooves, and all of them are arranged in a staggered manner along the second direction, which is not limited here. Similarly, the mounting sub-grooves in the second busbar mounting slot 112 may also include only the third mounting sub-groove 1121 and the fourth mounting sub-groove 1122, or may include more mounting sub-grooves, which is not limited here.

[0046] Furthermore, the first busbar mounting groove 111 and the second busbar mounting groove 112 are both used to set the busbar, and the busbar set in the first busbar mounting groove 111 and the busbar set in the second busbar mounting groove 112 have opposite electrical conduction properties. In other embodiments, the busbar set in the first busbar mounting groove 111 and the busbar set in the second busbar mounting groove 112 are respectively alternately connected to the positive polarity tabs and the negative polarity tabs of the battery cells, thereby connecting multiple battery cells in series.

[0047] In some embodiments, the plurality of first mounting sub-grooves 1111 and the plurality of second mounting sub-grooves 1112 are connected alternately in sequence along the first direction; and / or, the plurality of third mounting sub-grooves 1121 and the plurality of fourth mounting sub-grooves 1122 are connected alternately in sequence along the first direction. The plurality of first mounting sub-grooves 1111 and the plurality of second mounting sub-grooves 1112 are connected alternately in sequence along the first direction, which means that the first mounting sub-grooves 1111 and the second mounting sub-grooves 1112 are arranged adjacent to each other in the first direction, and there is no gap between the adjacent first mounting sub-grooves 1111 and the second mounting sub-grooves 1112 in the first direction, thereby improving the space utilization of the frame 11. Similarly, the plurality of third mounting sub-grooves 1121 and the plurality of fourth mounting sub-grooves 1122 are connected alternately in sequence along the first direction, which can also improve the space utilization of the frame 11. It should be noted that, the multiple first mounting sub-grooves 1111 and the multiple second mounting sub-grooves 1112 being alternately connected in sequence along the first direction means that along the first direction, the second mounting sub-groove 1112 of the previous first bus mounting groove 111 is connected with the first mounting sub-groove 1111 of the next first bus mounting groove 111; similarly, the multiple third mounting sub-grooves 1121 and the multiple fourth mounting sub-grooves 1122 being alternately connected in sequence along the first direction means that the third mounting sub-groove 1121 of the previous second bus mounting groove 112 is connected with the fourth mounting sub-groove 1122 of the next second bus mounting groove 112.

[0048] In some embodiments, multiple first mounting sub-grooves 1111 are connected with multiple second mounting sub-grooves 1112 through overlapping portions along the second direction, so that one bus can be installed in two connected mounting sub-grooves, thereby reducing the number of installation times of the bus; and / or, multiple third mounting sub-grooves 1121 are connected with multiple fourth mounting sub-grooves 1122 through overlapping portions along the second direction. Similarly, one bus can be installed in two connected mounting sub-grooves, thereby reducing the number of installation times of the bus.

[0049] In some embodiments, a first through slot 1113 for inserting a tab is provided at the bottom of the first busbar mounting slot 111. The first through slot 1113 is provided from the first mounting sub-slot 1111 and overlaps with the second mounting sub-slot 1112 along the second direction; and the first through slot 1113 connects the first mounting sub-slot 1111 and the second mounting sub-slot 1112 along the second direction. The first through slot 1113 is mainly used to allow the tab of the battery cell on the power core 4 to pass through, so that the tab of the battery cell can be electrically connected to the busbar located in the first busbar mounting slot 111. Providing the first through slot 1113 in the first busbar mounting slot 111 is conducive to saving the limited space of the frame 11, so that the first through slot 1113 does not occupy additional area of ​​the frame 11, but further provides a through slot on the basis of the first busbar mounting slot 111. And because the first through groove 1113 connects the first mounting sub-groove 1111 and the second mounting sub-groove 1112, when opening the first through groove 1113, there is no need to position and open the first through groove 1113 twice, and the through groove can be opened once at the connection point between the first mounting sub-groove 1111 and the second mounting sub-groove 1112.

[0050] And / or, the bottom of the second busbar mounting groove 112 is provided with a second through groove 1123 for inserting the pole ear, and the second through groove 1123 is opened from the third mounting sub-groove 1121 and overlaps with the fourth mounting sub-groove 1122 along the second direction. And the second through groove 1123 connects the third mounting sub-groove 1121 and the fourth mounting sub-groove 1122 along the second direction. The second through groove 1123 is mainly used to allow the pole ear of the battery cell on the power core 4 to pass through, so that the pole ear of the battery cell can be electrically connected to the bus located in the second busbar mounting groove 112. Providing the second through groove 1123 in the second busbar mounting groove 112 is conducive to saving the limited space of the frame 11, so that the second through groove 1123 does not occupy the area of ​​the frame 11 additionally, but further opens a through groove on the basis of the second busbar mounting groove 112. And because the second through groove 1123 connects the third mounting sub-groove 1121 and the fourth mounting sub-groove 1122, when opening the second through groove 1123, there is no need to position and open the second through groove 1123 twice, and the through groove can be opened once at the connection point between the third mounting sub-groove 1121 and the fourth mounting sub-groove 1122.

[0051] It should be noted that the area of ​​the busbar is larger than the contact area between the cell pole ear and the busbar, which is beneficial to increase the heat dissipation area and help the cell pole ear to dissipate heat. And for the first through groove 1113 connecting the first mounting sub-groove 1111 and the second mounting sub-groove 1112, it does not distinguish whether the connected first mounting sub-groove 1111 and the second mounting sub-groove 1112 belong to the same first busbar mounting groove 111, that is, the first through groove 1113 includes the first mounting sub-groove 1111 and the second mounting sub-groove 1112 connected in the same first busbar mounting groove 111, and also includes the second mounting sub-groove 1112 in a first busbar mounting groove 111 and the first mounting sub-groove 1111 in another first busbar mounting groove 111 adjacent thereto. For the second through groove 1123, it is the same as the first through groove 1113 and will not be repeated.

[0052] In some embodiments, along the first direction, in two adjacent first bus bar mounting grooves 111, a second mounting sub-groove 1112 in one first bus bar mounting groove 111 is provided with a third through groove 1114 for passing a pole ear, and the third through groove 1114 extends along the second direction and connects to the first mounting sub-groove 1111 in another first bus bar mounting groove 111, and the third through groove 1114 is located between the two adjacent first through grooves 1113. In other words, a third through slot 1114 is opened in a first busbar mounting slot 111, and the third through slot 1114 extends along the second direction to another first busbar mounting slot 111 adjacent to the first busbar mounting slot 111. The third through slot 1114 is located between two adjacent first through slots 1113, and the pole ears that were originally only allowed to be inserted into the first through slot 1113 are increased to the pole ears that can be inserted into both the first through slot 1113 and the third through slot 1114. The third through slots 1114 do not occupy other positions of the frame 11, but are regularly arranged in sequence along the first direction in each first busbar mounting slot 111. Compared with only setting the first through slot 1113, the number of pole ears can be increased without changing the area of ​​the frame 11.

[0053] And / or, along the first direction, in two adjacent second busbar mounting grooves 112, a fourth mounting sub-groove 1122 in one second busbar mounting groove 112 is provided with a fourth through-groove 1124 for passing a pole ear, the fourth through-groove 1124 extends along the second direction and communicates with the third mounting sub-groove 1121 in another second busbar mounting groove 112, and the fourth through-groove 1124 is located between two adjacent second through-grooves 1123. Similarly, the beneficial effects of providing the fourth through-groove 1124 are the same as those of providing the third through-groove 1114, and are not described in detail herein.

[0054] Further, a plurality of first isolation walls 12 and a plurality of second isolation walls 13 are provided on the side of the frame 11 away from the first busbar mounting groove 111. Each first isolation wall 12 is located between the adjacent first through groove 1113 and the third through groove 1114, and each second isolation wall 13 is located between the adjacent second through groove 1123 and the fourth through groove 1124. The first through groove 1113, the second through groove 1123, the third through groove 1113 and the fourth through groove 1124 are all used to allow the cell tabs to pass through so that the cell tabs can be electrically connected to the busbar, and the main parts of the plurality of cells 4 connected to the cell tabs are respectively located directly below the first through groove 1113, the second through groove 1123, the third through groove 1113 and the fourth through groove 1124. By providing the first isolation wall 12 and the second isolation wall 13, two adjacent cells 4 can be effectively isolated, and the first isolation wall 12 and the second isolation wall 13 here are mainly used to isolate the cell tab parts of the cell 4. Since the battery cell tabs are prone to heat up, isolating adjacent battery cell tabs with isolation walls can reduce heat concentration to a certain extent.

[0055] In some embodiments, the frame 11 is further provided with a first output slot 14 and a second output slot 15. A plurality of first busbar mounting slots 111 form a first slot group, and a plurality of second busbar mounting slots 112 form a second slot group. The first output slot 14 is arranged on one side of the first slot group along the first direction, and the first output slot 14 is connected to the first slot group, where the connection here means that the first output slot 14 is connected to the first busbar mounting slot 111 on one side of the first slot group. The second output slot 15 is arranged on the other side of the second slot group along the first direction, where the other side here is relative to the first output slot 14, and the second output slot 15 is connected to the second slot group, where the connection here means that the second output slot 15 is connected to the second busbar mounting slot 112 on one side of the second slot group. The first output slot 14 and the second output slot 15 are mainly used to set the output aluminum bar, and the output aluminum bar set in the first output slot 14 and the second output slot 15 has opposite electrical properties, thereby forming an output positive electrode and an output negative electrode, so that the battery module can be connected to an external device. The first output slot 14 is connected to the first slot group, so that the first output slot 14 can be close to the first slot group, thereby improving the space utilization of the frame 11. Similarly, the second output slot 15 is connected to the second slot group, which also has the effect of improving the space utilization of the frame 11.

[0056] And, along the first direction, the first output slot 14 and the second output slot 15 are respectively arranged on opposite sides of the frame 11; along the second direction, multiple first bus mounting slots 111 and multiple second bus mounting slots 112 are staggered along the second direction, so that the first bus mounting slots 111 and the second bus mounting slots 112 can compress the space as much as possible in the first direction, increase the number of bus mounting slots that can be opened in the frame 11, and improve the space utilization rate of the battery cell 4 bracket 1.

[0057] It should be noted that the first output slot 14 and the second output slot 15 can be arranged on the same side or on opposite sides along the first direction. In the present embodiment, the first output slot 14 and the second output slot are arranged on opposite sides.

[0058] Furthermore, conductive through holes 151 are provided on the bottom of the first output slot 14 and the second output slot 15 . The conductive through holes 151 can be provided with conductive posts or conductive posts connected to external devices to facilitate electrical connection between the battery module and external devices.

[0059] In some embodiments, the frame 11 is further provided with a harness groove 113. The harness groove 113 is located between the first groove group and the second groove group and extends along the first direction. The harness groove 113 is mainly used to place the harness, so that the harness can be stored in the harness groove 113, and the harness can extend along the harness groove 113, so that the harness can be distributed in each bus mounting groove, so as to electrically connect each bus mounting groove to complete information collection. The harness groove 113 is arranged between the first bus mounting groove 111 and the second bus mounting groove 112, which not only utilizes the area that must be set apart between the first bus mounting groove 111 and the second bus mounting groove 112, but also enables the harness groove 113 to extend through each bus mounting groove, which is convenient for wiring harness.

[0060] Furthermore, at least one temperature probe mounting hole 1131 is provided at the bottom of the wiring harness slot 113, so that a probe for monitoring temperature can extend to one side of the battery cell 4 through the temperature probe mounting hole 1131, without having to set a probe mounting position elsewhere on the frame 11, and the probe wiring can also be directly connected from the wiring harness slot 113, making wiring more convenient.

[0065] The multiple battery cells 4 in the battery module are mainly installed through the battery cell holder 1 described in the above embodiment, mainly by opening a plurality of staggered first bus mounting grooves 111 and a plurality of second bus mounting grooves 112 on the frame 11, and each first bus mounting groove 111 opens a staggered first mounting sub-groove 1111 and a second mounting sub-groove 1112, and each second bus mounting groove 112 opens a staggered third mounting sub-groove 1121 and a fourth mounting sub-groove 1122, and opens as many mounting sub-grooves as possible in the limited space of the frame 11, thereby improving the space utilization of the battery cell holder 1 and achieving higher density battery module installation. In detail, the first busbar mounting grooves 111 and the second busbar mounting grooves 112 are mainly provided on the frame 11, and the first busbar mounting grooves 111 and the second busbar mounting grooves 112 are arranged in a staggered manner along the second direction, so that the first busbar mounting grooves 111 and the second busbar mounting grooves 112 can compress the space as much as possible in the first direction, and increase the number of busbar mounting grooves that can be provided on the frame 11; further, each first busbar mounting groove 111 includes a staggered first mounting sub-groove 1111 and a second mounting sub-groove 1112, and each second busbar mounting groove 112 includes a staggered third mounting sub-groove 1121 and a fourth mounting sub-groove 1122, so that the structures of the first busbar mounting grooves 111 and the second busbar mounting grooves 112 are more compact, and the space utilization rate of the battery holder 1 can be further improved. While improving the space utilization rate of the battery holder 1, the number of integrated battery cells 4 is also increased, and the energy density of the battery module is improved.

[0066] It should be noted that, in this embodiment, see Figure 4 and Figure 5, the first conductive member 2 and the second conductive member 3 are both aluminum bars, and a plurality of first conductive members 2 constitute a series aluminum bar, and a plurality of second conductive members 3 also constitute a series aluminum bar. In the parallel embodiment, the first conductive member 2 and the second conductive member 3 have opposite conductivity, and the first conductive member 2 is defined as conducting positive electricity and the second conductive member 3 is defined as conducting negative electricity. The battery cell 4 has a positive electrode and a negative electrode, and the electricity of the positive electrode and the negative electrode is output through the first pole ear 41 and the second pole ear 42. In this embodiment, the first pole ear 41 is a positive pole ear, and the second pole ear 42 is a negative pole ear. The first pole ear 41 is connected to the first conductive member 2, so that the electricity of the battery cell 4 can be output to the first conductive member 2, and the second pole ear 42 is connected to the second conductive member 3, so that the electricity of the battery cell 4 can be output to the second conductive member 3, and the first conductive member 2 and the second conductive member 3 have the same shape and are shaped. A first conductive member 2 is disposed in a first mounting sub-groove 1111 and a second mounting sub-groove 1112 adjacent to each other along the second direction, and a second conductive member 3 is disposed in a third mounting sub-groove 1121 and a fourth mounting sub-groove 1122 adjacent to each other along the second direction. Such an arrangement can increase the area of ​​the first conductive member 2 and the second conductive member 3, reduce the number of times the conductive members are installed, improve the assembly efficiency of the conductive members, increase the heat dissipation area, and facilitate the heat dissipation of the tab.

[0067] In addition, the first pole tab 41 and the first conductive member 2 are connected by welding, and the second pole tab 42 and the second conductive member 3 are connected by welding. Compared with bolt connection, the risk of the pole tab being crushed can be avoided, and the connection standard is easier to unify.

[0068] In some embodiments, the battery module further includes a positive output aluminum bar and a negative output aluminum bar. The positive output aluminum bar is disposed in the first output slot 14, and the negative output aluminum bar is disposed in the second output slot 15. Both the positive output aluminum bar and the negative output aluminum bar are provided with output through holes, which are connected to the conductive through holes 151 to facilitate the arrangement or connection of the conductive column.

[0069] In some embodiments, the battery module further includes a collection harness 5 having a plurality of branch lines and a collection connector 6. One end of the collection harness 5 is connected to the collection connector 6, and the collection connector 6 is used to integrate the current, voltage and temperature conditions of the plurality of battery cells 4 collected by the collection harness 5 and connect to an external detection device to collect information of the battery cells 4. A harness slot 113 is provided on the frame 11, and the harness slot 113 is located between the first busbar mounting slot 111 and the second busbar mounting slot 112 and extends along the first direction. One end of the collection harness 5 away from the collection connector 6 extends into the harness slot 113, and a plurality of branch lines are respectively connected to the first conductive member 2 and the second conductive member 3 to collect current and voltage information of each battery cell 4.

[0070] Furthermore, at least one temperature collection probe 51 branches out from the collection harness 5, and at least one temperature probe mounting hole 1131 is provided at the bottom of the harness slot 113. Each temperature collection probe 51 extends to one side of the battery cell 4 through a temperature probe mounting hole 1131 for monitoring the temperature of the battery cell 4.

[0071] In some embodiments, a plurality of battery cells 4 are arranged in sequence along the first direction. Due to the adjacent through-slot structure of the battery cell holder 1, the distance between two adjacent battery cells 4 is very small, and the structure is more compact. In order to avoid a large amount of heat and heat concentration between adjacent battery cells 4, a separator 7 is provided between adjacent battery cells 4. The separator 7 has a low thermal conductivity and is insulating, and can isolate the temperature between adjacent battery cells 4. On the one hand, it can make the temperature acquisition probe 51 more accurate in monitoring the temperature of the battery cell 4. On the other hand, it can prevent the battery cells 4 from influencing each other, reduce and delay the propagation speed of thermal runaway between the battery cells 4, so as to ensure a safe reaction time and provide the safety of the battery module.

[0072] In some embodiments, among the multiple battery cells 4 arranged in sequence along the first direction, the first and last battery cells 4 are both provided with an insulating plate 9 on the side facing away from the other battery cells 4 to form basic protection for the multiple battery cells 4 .

[0073] Furthermore, the battery module includes a glass fiber tape 8. The plurality of battery cells 4 are arranged in sequence along the first direction, and the glass fiber tape 8 is wound around the outer sides of the battery cells 4 to bundle the plurality of battery cells 4 together, thereby fixing the plurality of battery cells 4. Compared with the method of fixing with a steel belt and an end side plate in the related art, the use of the glass fiber tape 8 is lower in cost and simpler in fixing.

[0074] The battery module in this embodiment can be used as a power battery for new energy vehicles, new energy operating machinery, etc.
