Description

[0001] This utility model relates to the field of battery technology, and in particular to a data acquisition component and a battery module. Background Technology

[0002] To collect voltage and temperature data from the battery module, a sampling circuit electrically connected to the battery module is typically required. This includes information acquisition units such as FPC, FFC, FDC, and acquisition harnesses. The sampling terminals of these acquisition units are soldered to the busbars of the battery module to collect the data.

[0003] The aforementioned sampling circuit connection method means that the welding quality between the information acquisition unit and the busbar directly affects the accuracy of signal acquisition and indirectly impacts the performance of the battery module. Furthermore, the fixed connection between the information acquisition unit and the busbar prevents the information acquisition unit from being disassembled from the busbar without damage. This means the information acquisition unit cannot be reused when acquiring information from the next battery module, increasing costs.

[0004] Therefore, a new solution is needed to address the aforementioned technical problems. Utility Model Content

Detailed Implementation

[0019] The following specific examples 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. This utility model can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0022] Please see Figures 1 to 5 This utility model provides a data acquisition component, including an information acquisition unit 1 and a connection terminal 2. The information acquisition unit 1 is used for electrical connection with a battery management system. The connection terminal 2 includes a first connection component 21 and a second connection component 22 connected together. The first connection component 21 is electrically connected to the information acquisition unit 1, and the second connection component 22 is used for electrical connection with a busbar (not shown). That is, through the connection terminal 2, the information acquisition unit 1 can achieve electrical connection with the busbar, thereby enabling the information acquisition unit 1 to acquire information from the battery module.

[0023] It should be noted that the second connecting component 22 is detachably connected to the busbar, allowing the data acquisition component to be reused. This means the same data acquisition component can be used to acquire information from different battery module models, which helps reduce the cost of data acquisition from battery modules. It is understood that the first connecting component 21 of the connecting terminal 2 can be fixedly connected to the information acquisition unit 1, or it can be detachably connected to the information acquisition unit 1.

[0024] Specifically, the second connecting component 22 is provided with a plug-in portion 221 and an elastic pressing portion 222, with the elastic pressing portion 222 disposed within the plug-in portion 221. The plug-in portion 221 is used to plug into and cooperate with the busbar. When the busbar is inserted into the plug-in portion 221 under the action of external force, the elastic pressing portion 222 is used to press the busbar against the plug-in portion 221 to realize the electrical connection between the busbar and the second connecting component 22, that is, to realize the electrical connection between the battery module and the acquisition component.

[0025] Furthermore, to improve the stability of the connection between the busbar and the second connecting component 22, the elastic pressing part 222 is provided with a first limiting structure 2221 that cooperates with the busbar. After the busbar is inserted into the plug-in part 221, the first limiting structure 2221 is used to limit the busbar within the plug-in part 221, preventing poor contact between the busbar and the plug-in part 221 or the busbar from coming out of the plug-in part 221 during the information collection process of the battery module. This helps to ensure the accuracy and continuity of the information collection unit 1 in collecting information from the battery module.

[0026] After the battery module information is collected, the busbar needs to be pulled out of the connector 221. With the first limiting structure 2221 provided in the elastic pressing part 222, the elastic pressing part 222 extends at least partially out of the connector 221 to form a pressing release part 223. The pressing release part 223 can deform the elastic pressing part 222 under external force, causing the elastic pressing part 222 to move away from the busbar, thereby causing the first limiting structure 2221 to move away from the busbar, achieving the purpose of releasing the busbar.

[0027] Please see Figures 3 to 5 In some embodiments, the first connecting component 21 and the second connecting component 22 are integrally formed, avoiding the assembly of the connecting terminal 2 and also improving the stability of the connecting terminal 2 structure. Furthermore, to achieve electrical connection between the connecting terminal 2 and the information acquisition unit 1 and the busbar, both the first connecting component 21 and the second connecting component 22 are made of conductive materials, such as conductive metals.

[0028] In one example, the second connecting component 22 includes a base plate 224, a support plate 225, and a limiting plate 226. The support plate 225 is connected to the base plate 224, and the limiting plate 226 is connected to the side of the support plate 225 opposite to the base plate 224. Specifically, support plates 225 are connected to opposite sides of the base plate 224, and the line connecting the two support plates 225 is perpendicular to the insertion direction of the busbar. The limiting plate 226 is disposed opposite to the base plate 224, and there is a certain gap between them, so that the base plate 224, the support plate 225, and the limiting plate 226 form a U-shaped structure, forming the insertion part 221.

[0029] It should be noted that the support plate 225 is designed to limit the width of the busbar inserted into the connector 221.

[0030] In one example, the elastic pressing part 222 is configured as an elastic member and a pressing plate connected together. The pressing plate is disposed away from the base plate 224 and towards the limiting plate 226, and the end of the elastic member away from the pressing plate is connected to the base plate 224. It should be noted that the elastic member is elastic and can extend and retract between the pressing plate and the base plate 224.

[0031] In another example, the elastic pressing part 222 is configured as an elastic plate, which is connected to the base plate 224 and located between the base plate 224 and the limiting plate 226, and the elastic plate arches toward the limiting plate 226.

[0032] When the busbar is inserted into the connector 221, the busbar is compressed by the elastic plate under the action of external force. The elastic plate deforms, increasing the minimum distance between the elastic plate and the limiting plate 226, so that the busbar can be inserted into the connector 221. After the external force disappears, the elastic plate applies a force towards the limiting plate 226 under its own restoring force, so that the busbar abuts against the limiting plate 226. At this time, the two opposite sides of the busbar parallel to the base plate 224 are in contact with the limiting plate 226 and the elastic plate respectively, so that the busbar is electrically connected to the second connecting component 22, that is, the battery module and the acquisition component are electrically connected.

[0033] For example, the fixed end of the elastic plate is connected to the base plate 224, and the connection point between the two is located at the insertion end of the plug-in portion 221. Because the elastic plate arches towards the limiting plate 226, a first guide surface 2222 is formed on the side of the elastic plate near the insertion end of the plug-in portion 221, and a second guide surface 2261 is provided on the side of the limiting plate 226 near the insertion end of the plug-in portion 221. When the busbar is inserted into the plug-in portion 221, the first guide surface 2222 and the second guide surface 2261 guide the insertion of the busbar.

[0034] It should be noted that the fixed end of the elastic plate is one end in the direction of extension of the elastic plate.

[0035] In one example, the first limiting structure 2221 is configured as a limiting protrusion protruding from the elastic plate, such as a cylindrical structure or an arc structure, and the limiting protrusion is located on the side of the elastic plate facing the limiting plate 226. The busbar is configured with a limiting hole that mates with the limiting protrusion. The limiting of the busbar is achieved through the cooperation of the limiting protrusion and the limiting hole.

[0036] In another example, the first limiting structure 2221 is a limiting hole provided on the elastic plate, which extends through the elastic plate. In this case, the busbar is configured with a limiting protrusion that mates with the limiting hole. Through the cooperation of the limiting hole and the limiting protrusion, the busbar is limited.

[0037] In this example, the free end of the elastic plate is connected to the pressure release part 223 so that the pressure release part 223 can cause the elastic plate to deform. It should be noted that the fixed end and the free end of the elastic plate are opposite ends in the extension direction of the elastic plate.

[0038] In some embodiments, for ease of operation, the pressure release part 223 is located on the same side of the base plate as the elastic plate. The pressure release part 223 includes a pressing plate 2231 and an adapter 2232 connected to each other. The end of the adapter 2232 away from the pressing plate 2231 is connected to the free end of the elastic plate. The pressing plate 2231 is spaced apart from the base plate 224 via the adapter 2232 to facilitate pressing operation. Furthermore, the base plate 224 is provided with a clearance hole 2241 to accommodate the pressure release part 223. The pressure release part 223 can extend into the clearance hole 2241 under the action of external force. The elastic plate deforms and moves away from the busbar under the action of the pressure release part 223, thereby releasing the busbar and allowing it to be pulled out from the insertion part 221.

[0039] Specifically, when it is necessary to pull the busbar out of the plug-in portion 221, pressing the pressing plate 2231 causes the adapter 2232 to extend into the clearance hole 2241. The elastic plate deforms under the action of the adapter 2232 and moves away from the limiting plate 226, thereby increasing the distance between the elastic plate and the limiting plate 226 so that the busbar can be separated from the first limiting structure 2221, and then the busbar can be pulled out of the plug-in portion 221.

[0040] For example, the adapter 2232 is arranged perpendicularly to the base plate 224, and the pressing plate 2231 is located above the base plate 224 and is arranged parallel to the base plate 224.

[0041] In one example, a limiting plate 226 is connected to two support plates 225 simultaneously.

[0042] In another example, each support plate 225 is connected to a limiting plate 226, with a gap between the two limiting plates 226. The elastic pressing part 222 includes two elastic plates, and each limiting plate 226 is correspondingly provided with an elastic plate. This helps to reduce the contact area between the busbar and the elastic plates and limiting plates 226, which helps to reduce the damage to the busbar caused by the insertion part 221 during the insertion of the busbar, and thus helps to improve the service life of the busbar.

[0043] Furthermore, the pressure release part 223 is connected to at least one elastic plate, which simplifies the operation when the busbar is pulled out of the insertion part 221. In this embodiment, one pressure release part 223 is connected to two elastic plates simultaneously, so that the deformation of all elastic plates can be controlled by one pressure release part 223, which helps to simplify the structure and facilitates operation.

[0044] In some embodiments, the information acquisition unit 1 includes at least one third connecting component 11, which is electrically connected to a first connecting component 21. Simultaneously, each third connecting component 11 is connected to a battery cell (not shown) within the battery module. It should be noted that the number of third connecting components 11 can be adaptively set according to the number of battery cells in the battery module, to satisfy the requirement of completing information acquisition of all battery cells in the battery module at once, or to satisfy the requirement of acquiring information of the battery cells in the battery module in batches.

[0045] In some embodiments, in order to enable the connection terminal 2 to be compatible with information acquisition units 1 of different structural forms, the first connection component 21 of the connection terminal 2 is configured with different structural forms to match the structural form of the information acquisition unit 1.

[0046] In one example, the information acquisition unit 1 is configured as a flexible circuit board, the third connecting component 11 is configured as a flat plate structure extending outward from the flexible circuit board, and the first connecting component 21 is also configured as a flat plate structure. By soldering the first connecting component 21 onto the third connecting component 11 of the flexible circuit board, the information acquisition unit 1 and the first connecting component 21 are electrically connected, that is, the information acquisition unit 1 and the terminal block 2 are electrically connected.

[0047] In another example, the information acquisition unit 1 is configured as an acquisition harness, which has at least one wire bundle, and the third connecting component 11 is a connecting segment near the end of the wire bundle. The first connecting component 21 is configured as an arc-shaped structure, and the connecting segment of the wire bundle is placed inside the hollow interior of the first connecting component 21. The connecting component 21 is then clamped by a wire clamping tool to achieve an electrical connection between the information acquisition unit 1 and the first connecting component 21, that is, an electrical connection is achieved between the information acquisition unit 1 and the terminal block 2.

[0048] Please see Figures 5 to 8 This utility model also provides a battery module that uses the aforementioned acquisition component to collect information from the battery module. The battery module includes a busbar 3 and battery cells 4. At least one battery cell 4 is provided, and each battery cell 4 is electrically connected to at least one busbar 3. The busbar 3 is electrically connected to the second connection component 22 of the acquisition component. Through the busbar 3, the acquisition component can collect information such as the temperature and voltage of the battery cells 4 and transmit the collected information to the battery management system, thereby realizing real-time monitoring of the voltage and temperature of the battery module, which helps to ensure the safety of the battery module.

[0049] Specifically, each battery unit 4 includes multiple individual cells 41, and a busbar 3 is electrically connected to each individual cell 41 within a battery unit 4. Furthermore, the busbar 3 is detachably electrically connected to the second connection component 22 of the acquisition assembly, enabling the acquisition assembly to collect information from different types of battery modules. This facilitates the reuse of the acquisition assembly and reduces the information collection cost of the battery module.

[0050] The busbar 3 includes a plug plate 31. During the connection process between the busbar 3 and the acquisition component, the plug plate 31 is inserted into the plug portion 221 of the second connecting component 22 under the action of external force. The plug plate 31 abuts against the plug portion 221 under the action of the elastic pressing portion 222 of the second connecting component 22, so that the plug plate 31 and the second connecting component 22 maintain an electrical connection, that is, maintain the electrical connection between the battery module and the acquisition component.

[0051] Furthermore, to prevent poor contact between the insert plate 31 and the plug-in portion 221, or to prevent it from dislodging from the plug-in portion 221, a second limiting structure 32 is provided on the insert plate 31. This second limiting structure 32 matches the first limiting structure 2221 on the elastic pressing portion 222 to limit the busbar 3 within the plug-in portion 221. When it is necessary to pull the busbar 3 out of the plug-in portion 221, the busbar 3 is released through the pressing release portion 223 of the second connecting member 22, causing the busbar 3 to disengage from the plug-in portion 221.

[0052] Please see Figure 8 For example, when the first limiting structure 2221 is a limiting protrusion, the second limiting structure 32 is a limiting hole. In another example, when the first limiting structure 2221 is a limiting hole, the second limiting structure 32 is a limiting protrusion.

[0053] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
