Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing, specifically a battery module separator with high buffering capacity and limiting function. Background Technology

[0002] During the assembly process of lithium battery modules, end plates and side plates are needed to securely constrain the stacked cells. The separator, as a key functional component between the end plates and the cells, must simultaneously perform multiple functions including mechanical buffering, insulation protection, heat conduction, and structural support. With the increasing prevalence of high-energy-density batteries and the increasing integration of battery modules, the performance of the separator directly affects the module's lifespan, safety, and energy efficiency. In existing technologies, buffer materials such as foam and mica sheets are typically used between the aluminum end plates on both sides of the battery module and the cells. However, a single buffer material cannot secure integrated busbars after cell assembly, failing to provide a limiting function and thus having a limited functionality. Utility Model Content

[0003] The purpose of this invention is to provide a battery module separator with high buffering capacity and limiting function to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A battery module separator with high buffering capacity and limiting function includes a separator panel, and a cell locking structure is fixedly connected to the top of the separator panel. The cell locking structure includes a locking top plate that is vertically fixedly connected to the top of the separator panel. The locking top plate is the same width as the separator panel. Locking side plates are vertically fixedly connected to both ends of the locking top plate. The locking side plates are located below the locking top plate and are also vertically fixedly connected to the separator panel. The locking top plate and the locking side plates on both sides together form a locking structure on the top of the separator panel.

[0006] In a further embodiment, the top of the locking top plate is provided with a module aluminum busbar connection structure.

[0007] In a further embodiment, the module aluminum busbar connection structure consists of several vertically fixed limiting columns connected to the top of the locking top plate.

[0008] In a further embodiment, the limiting columns comprise two sets symmetrically distributed at both ends of the locking top plate, and each set contains no fewer than two limiting columns.

[0009] Preferably, the partition panel and the battery cell locking structure are both made of ABS+PC composite material.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] I. This utility model uses a battery module separator that is the same size as the battery cell. When the battery cells are assembled, the top plate is attached to the top of the battery cell and the side plate is attached to the side of the battery cell, thereby playing a unified role in locking and limiting the battery cells.

[0012] Second, this utility model uses a limiting column to allow the battery cell busbar and other components to be placed on top of the battery module partition and fixed by the limiting column. When the battery cell module vibrates, the limiting column can effectively restrict the busbar and other structures to prevent them from shifting.

[0013] Third, this utility model is made of ABS+PC composite material. When the battery module is subjected to force, it can play a buffering role and prevent the force from being applied directly to the battery cell. Moreover, the separator has good insulation effect and can effectively insulate the battery cell and the end plates at both ends. In addition, the separator has good heat insulation performance and can effectively avoid the risk of thermal runaway caused by local temperature rise. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Implementation, for example Figure 1-2As shown, this embodiment provides a battery module separator with high buffering capacity and limiting function, including a separator panel 1. A cell locking structure is fixedly connected to the top of the separator panel 1. The cell locking structure includes a locking top plate 2 vertically fixedly connected to the top of the separator panel 1. The locking top plate 2 is the same width as the separator panel 1. Locking side plates 3 are vertically fixedly connected to both ends of the locking top plate 2. The locking side plates 3 are located below the locking top plate 2 and are also vertically fixedly connected to the separator panel 1. The locking top plate 2 and the locking side plates 3 on both sides together form a locking structure at the top of the separator panel 1. In this embodiment, by using a battery module separator with the same size as the cell 5, when the cells 5 are assembled, the locking top plate 2 is attached to the top of the cell 5, and the locking side plates 3 are attached to the sides of the cell 5, thereby uniformly playing a locking and limiting role for the cell 5.

[0019] The top of the locking top plate 2 is equipped with a module aluminum busbar connection structure. This connection structure consists of several vertically fixed limiting columns 4 connected to the top of the locking top plate 2. The limiting columns 4 comprise two sets symmetrically distributed at both ends of the locking top plate 2, with each set containing at least two limiting columns 4. In this embodiment, the limiting columns 4 allow the busbar 6 and other components to be placed on top of the battery module separator and fixed in place. When the battery cell 5 module vibrates, the limiting columns 4 effectively restrict the busbar 6 and other structures, preventing displacement.

[0020] The separator panel 1 and the cell locking structure are both made of ABS+PC composite material. In this embodiment, the overall structure uses ABS+PC composite material, which acts as a buffer when the battery module is subjected to force, preventing the force from being directly applied to the cell 5. Furthermore, the separator has good insulation properties, effectively insulating the cell 5 and its end plates 7. In addition, the separator has good thermal insulation performance, effectively avoiding the risk of thermal runaway caused by localized temperature increases.

[0021] During installation, follow the sequence of end plate 7 - partition panel 1 and cell locking structure - cell 5 - partition panel 1 and cell locking structure - end plate 7. The connection between the various structures will not be elaborated here.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
