[0037] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0038] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effects and objectives of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0039] See Figures 1 to 6In some optional embodiments, this utility model provides a cell assembly module 100, which includes multiple cell stacks 1, multiple connecting beams 2, and two side plate assemblies 3. In addition to the above-mentioned components, the cell assembly module may also include a Battery Management System (BMS). Multiple cell stacks 1 are arranged along a first direction, and each cell stack 1 includes multiple cells 11 stacked along a second direction. Connecting beams 2 are arranged at both ends of each cell stack 1 along the first direction, and two side plate assemblies 3 are distributed along the second direction on both sides of the cell stack 1. Each side plate assembly 3 includes multiple side plate segments 31 distributed along the first direction and detachably connected. The side plate segments 31 located on both sides of the same cell stack 1 are detachably connected to the connecting beams 2 located at the corresponding ends of the cell stack 1, and clamp and fix the cell stack 1 during connection. That is, the side plate segments 31 located around the same cell stack 1 and the connecting beams 2 are interconnected to provide preload force to fix the cell stack 1.

[0040] In this application, the first direction is perpendicular to the second direction. Specifically, the arrangement direction of the multiple cell stacks 1, the arrangement direction of the multiple side plate segments 31 in each side plate group 3, the length direction of the side plate segments 31, the arrangement direction of the multiple connecting beams 2, the length direction of the cell stack 1, and the length direction of the cell 11 are the same as the first direction, i.e., the X direction in the figures; the arrangement direction of the multiple cells 11 in each cell stack 1, the arrangement direction of the two side plate groups 3, the length direction of the connecting beams 2, the width direction of the cell stack 1, and the thickness direction of the cell 11 are the same as the second direction, i.e., the Y direction in the figures.

[0041] Optionally, some of the connecting beams 2 are end beams, and the other part are intermediate beams. Specifically, the connecting beam 2 located between two adjacent cell stacks 1 is an intermediate beam, which can correspond to two cell stacks 1 at the same time, and the connecting beam 2 located on the side is an end beam, which corresponds to one cell stack 1.

[0042] Optionally, multiple side plate segments 31 of the same side plate group 3 correspond one-to-one with multiple battery cell stacks 1. That is, each battery cell stack 1 has an independent side plate segment 31 arranged on each side along the second direction. The assembly is simple and flexible. The number of side plate segments 31 in the side plate group 3 can be increased or decreased according to the actual number of battery cell stacks 1, so as to meet the needs of different charge levels and facilitate universal setting.

[0043] Optionally, the side plate segment 31 can be an aluminum profile, an injection-molded part, or a die-cast part. The side plate segment 31 has a first connecting part 311 corresponding to the connecting beam 2, and the first connecting part 311 is connected and locked to the connecting beam 2 by a first locking member 41. Further, the first locking member 41 includes a bolt, which makes the connection simple, convenient, and reliable.

[0044] Optionally, the two ends of the cell stack 1 distributed along the first direction are electrode tabs. There is a gap between the connecting beam 2 and the electrode tabs of the cell stack 1. That is, the length of the side plate segment 31 is greater than the length of the cell stack 1, so that the connecting beam 2 does not contact the electrode tabs of the cell stack 1. This helps to avoid squeezing the electrode tabs and affecting the performance of the cell stack 1, and also helps to ensure the insulation effect. The side plate segments 31 located on both sides of the same cell stack 1 cooperate to clamp and fix the cell stack 1 along the second direction. The two sides of the cell 11 distributed along the second direction are the sides with the largest surface area of ​​the cell 11. The two side plate segments 31 cooperate to clamp the sides with the largest surface area of ​​the cell 11, which helps to improve the stability of the overall structure.

[0045] Optionally, cell 11 may include pouch cells.

[0046] In the above embodiment, the battery cell assembly module, with the side plate assembly 3 cooperating with the connecting beam 2, can provide pre-tightening force to clamp the battery cell stack 1 to fix the battery cell stack 1. The structure is stable and does not require additional support plates to support the battery cell stack 1, which can meet the transportation requirements, thus reducing production steps and costs. In addition, the side plate assembly 3 includes multiple independently set side plate segments 31. The side plate segments 31 can be detachably connected to each other and to the connecting beam 2, which facilitates flexible assembly according to the number of battery cell stacks 1, avoids space waste, and helps to improve space utilization and further reduce costs.

[0047] See Figures 1 to 6 In some optional embodiments, the connecting beam 2 located between two adjacent battery cell stacks 1 is an intermediate beam among the multiple connecting beams 2. The two adjacent battery cell stacks 1 are separated by the intermediate beam. The first connecting parts 311 of the two adjacent side plate segments 31 in the same side plate group 3 are stacked to form an overlapping structure 312 corresponding to the same intermediate beam. The first locking member 41 passes through the overlapping structure 312 and is connected and locked with the intermediate beam.

[0048] Optionally, the side plate segment 31 is an injection-molded part, and the two first connecting parts 311 forming the overlapping structure 312 are stacked along the second direction. The first locking member 41 passes through the overlapping structure 312 along the second direction and is connected and locked to the intermediate beam. The stacking direction of the two first connecting parts 311 is the same as the direction in which the side plate segment 31 clamps the battery cell stack 1, which makes installation and adjustment simple and convenient, and helps to reduce the requirements for installation tolerance, thereby reducing the difficulty of production. Furthermore, the first locking member 41 includes a bolt, and the connecting beam 2 is provided with a threaded sleeve 42 that cooperates with the bolt for locking. One end of the bolt passes through the overlapping structure 312 and is threadedly connected to the threaded sleeve 42, making the connection simple and convenient.

[0049] Optionally, one of the two first connecting parts 311 forming the overlapping structure 312 has an L-shaped cross-section, and the other first connecting part 311 has an inverted L-shaped cross-section that fits and conforms to the L-shaped structure. The structure is simple and the connection and assembly are convenient.

[0050] In the above embodiment, two adjacent side plate segments 31 are connected to the same intermediate beam, so that two battery cell stacks 1 can share the same intermediate beam, which helps to simplify the structure. Moreover, multiple side plate segments 31 and connecting beams 2 can be connected to each other as a whole, which helps to improve the overall structural rigidity of the battery cell module.

[0051] See Figures 1 to 6 In some optional embodiments, the battery management system includes a main control board and a plurality of slave control boards 91, which are mounted and fixed on the side plate section 31 and electrically connected to the cell stack 1 corresponding to the side plate section 31.

[0052] Optionally, each side plate segment 31 is equipped with a slave control board 91, which is electrically connected to the cell stack 1 corresponding to the side plate segment 31, so as to diagnose and control the cell stack 1 according to the voltage signals of the multiple cells 11 in the cell stack 1.

[0053] The main control board is connected to multiple slave control boards 91. The slave control boards 91 can collect the voltage signal of the battery cell 11 through a flexible printed circuit (FPC). The main control board diagnoses and controls each battery cell 11 through the multiple slave control boards 91.

[0054] The battery cell module in the above embodiment can be assembled into a battery device without a casing, so that it can be directly installed and used in the future, which helps to simplify the subsequent installation and use process.

[0055] See Figures 7 to 11In some alternative embodiments, the side plate segment 31 is a die-cast part, and the connecting beam 2 is provided with a second connecting part 21 facing the side plate segment 31. The second connecting part 21 and the two first connecting parts 311 are stacked in a third direction. The first locking member 41 passes through the first connecting part 311 and the second connecting part 21 in a third direction to lock the side plate segment 31 and the connecting beam 2.

[0056] In this application, the height direction of the cell stack 1, the height direction of the connecting beam 2, the height direction of the side plate segment 31, the height direction of the cell 11 and the third direction are the same, namely the Z direction in the figure.

[0057] Optionally, the second connecting portion 21 on each end of the end beam is superimposed on the first connecting portion 311 on only one side plate segment 31 in the third direction; the second connecting portion 21 on each end of the intermediate beam is superimposed on the first connecting portion 311 of two adjacent side plate segments 31 in the same side plate group 3 in the third direction, and the second connecting portion 21 is located between the two first connecting portions 311.

[0058] The battery cell module described in the above embodiment is easy to assemble and helps to reduce the space requirements for assembly operations.

[0059] See Figures 1 to 11 In some optional embodiments, the present invention also provides a battery pack 200, including a cell assembly module 100 as described in any of the above embodiments and a plate-shaped lower housing 5. Side plate segments 31 are connected to the lower housing 5 to mount the cell stack 1 onto the lower housing 5. The side plate assembly 3 and connecting beam 2 in the cell assembly module cooperate to fix the cell stack 1, eliminating the need for additional beam structures on the outer periphery of the plate-shaped lower housing 5 to secure the cell stack 1. This simplifies the structure, reduces weight, and lowers costs.

[0060] Optionally, the battery pack also includes a top cover 8, which is sealed to the lower housing 5 to define an installation space for accommodating the cell stack 1. The installation space is filled with coolant that submerges the cell stack 1. Furthermore, the outer shell formed by the connection of the top cover 8 and the lower housing 5 is provided with an inlet and an outlet. Coolant is filled into the installation space from the inlet until it flows out from the outlet, so that the coolant fills the installation space completely. The cell stack 1 in the installation space is completely submerged in the coolant, achieving immersion cooling with good cooling effect.

[0061] Optionally, the lower housing 5 is provided with a reinforcing protrusion 6 corresponding to the side plate section 31. The reinforcing protrusion 6 and the side plate section 31 are connected and locked together by a locking structure 7. Further, the locking structure 7 includes a threaded connection structure, with a portion of the locking structure 7 passing through the side plate section 31 along a third direction to connect and lock with the reinforcing protrusion 6. When the second connecting part 21 and the first connecting part 311 are stacked along a third direction and locked together by the first locking member 41, the first locking member 41 passes through the first connecting part 311 and the second connecting part 21 and connects with the reinforcing protrusion 6. The installation direction of the first locking member 41 is the same as the installation direction of the locking structure 7, which helps to reduce the requirements for installation space and thus further improves space utilization. The threaded connection structure includes a second locking member and a locking sleeve. The second locking member includes a bolt, and the locking sleeve includes a nut or a threaded sleeve. The locking sleeve is disposed on the reinforcing protrusion 6.

[0062] Optionally, the battery pack 200 contains only one cell module 100. The assembled cell module 100 can be directly installed into the lower casing 5 of the battery pack 200, simplifying the subsequent installation steps and making the installation simple and efficient.

[0063] For details, see Figure 6 During the assembly process, the side plate section 31 of the side plate assembly 3 is connected to the connecting beam 2 to clamp and fix the corresponding cell stack 1. The slave control board 91 of the battery management system is fixed on the side plate section 31 and electrically connected to the corresponding cell stack 1. After the cell assembly module 100 is assembled, the assembled cell assembly module 100 is placed on the lower housing 5. The side plate section 31 is connected and fixed to the lower housing 5 to fix the cell assembly module 100. The upper cover 8 is installed and sealed to the lower housing 5 to define the installation space. Coolant is poured into the installation space and the coolant immerses the cell stack 1 to achieve immersion cooling, thus completing the final assembly.

[0064] The battery pack in the above embodiment can be directly installed on the lower housing 5 of the battery pack after the cell assembly module is completed. The structure is simple and the installation operation is simple and convenient.

[0065] See Figure 6 and Figure 12 In some alternative embodiments, the present invention also provides a vehicle 300, including a battery cell module 100 as described in any of the above embodiments. The bottom of the vehicle 300 has an installation space 301, and the battery cell module 100 is installed in the installation space 301 to form a power supply module for the vehicle.

[0066] Optionally, the vehicle 300 has a chassis with an installation space 301. The battery cell module 100 can be connected to the chassis so that it can be directly installed in the installation space 301, resulting in a simple structure and compact layout, which is beneficial for improving space utilization. Furthermore, the side plate section 31 of the battery cell module 100 is connected to the chassis to fix the battery cell stack 1.

[0067] Optionally, the vehicle may have only one battery cell module 100. The assembled battery cell module 100 can be directly installed into the vehicle’s installation space 301. The overall structure of the battery cell module 100 does not require secondary assembly, which simplifies the later installation steps and makes the installation simple and efficient.

[0068] In the vehicle described above, the battery cell module can be directly installed in the vehicle's installation space after assembly. The vehicle's shell protects the battery cell module, eliminating the need for an additional outer shell to protect it. This simplifies the structure and helps reduce costs.

[0069] The battery cell module, battery pack, and vehicle of this utility model are connected and cooperated by the side plate group 3 and the connecting beam 2 to achieve the fastening of the battery cell stack 1. The overall structure is stable and reliable. While meeting transportation requirements, the structure is simplified.
