Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a battery module, a battery device, and a vehicle. Background Technology

[0002] In the field of battery technology, battery modules typically include multiple cell groups. In order to achieve parallel or series connection between multiple cell groups, busbars are usually used to electrically connect multiple cell groups. However, due to the space limitations of battery modules, the distance between the positive and negative electrodes of battery modules is generally small, which makes it easy for short circuits to occur between the positive and negative electrodes.

[0003] In related technologies, battery modules are specially equipped with output electrode insulating bases to electrically isolate the positive and negative electrodes. However, the output electrode insulating bases need to be assembled separately, which increases the number of processing steps for battery modules, makes the assembly process cumbersome, and reduces production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a battery module, battery device and vehicle to overcome the problems of complicated assembly process and low production efficiency of battery modules in related technologies.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] According to a first aspect of this application, this application provides a battery module, which includes a battery cell assembly, a busbar, a positive output electrode, and a negative output electrode. The busbar includes an insulating base and a busbar body disposed on the insulating base. The busbar body is electrically connected to the battery cell assembly and is connected to the positive output electrode and the negative output electrode. The insulating base includes a connected main body and an isolation part. The busbar body is disposed on the main body, the positive output electrode and the negative output electrode are located at one end of the busbar body, and the isolation part is located between the positive output electrode and the negative output electrode.

[0007] According to the above-mentioned technical means, by integrating the isolation part and the main body part used for electrical isolation of the positive output electrode and the negative output electrode to form an insulating base, it is no longer necessary to set up a separate output electrode insulating base while effectively ensuring electrical safety. This helps to reduce the number of parts and simplify the assembly steps, thereby improving the production efficiency of battery modules.

[0008] In one possible implementation, the height of the isolation section is greater than the height of the main body section.

[0009] Based on the above technical means, the isolation section can form a physical isolation between the positive output pole and the negative output pole, so as to effectively avoid electrical faults such as short circuits between the positive output pole and the negative output pole.

[0010] In one possible implementation, the isolation section has a cavity.

[0011] The above-mentioned technical means are conducive to achieving a lightweight design for the insulating base.

[0012] In one possible implementation, a first reinforcing groove is formed on the surface of the insulating base. The first reinforcing groove includes a first sub-groove and a second sub-groove that are continuous and connected. The first sub-groove is located in the main body and the second sub-groove is located in the isolation part.

[0013] Based on the above-mentioned technical means, the structural strength and rigidity of the entire insulating base can be improved without significantly increasing the weight, and the connection area between the isolation part and the main body can be prevented from becoming a weak area, thus avoiding damage to the insulating base.

[0014] In one possible implementation, a notch is formed on one end face of the isolation portion along the height direction, and a reinforcing flange is formed on the other end face of the isolation portion.

[0015] Based on the aforementioned technical means, the notch and reinforced flange design can enhance the structural strength of the isolation section.

[0016] In one possible implementation, the battery module further includes an insulating sheet covering the side of the busbar away from the battery cell assembly. The insulating sheet includes a connected sheet-like body and a protrusion. The sheet-like body covers the busbar body and the main body. The protrusion is opposite to both the positive output terminal and the negative output terminal.

[0017] Based on the above technical means, the insulating sheet can provide electrical isolation protection, and the sheet-like body can prevent short circuits between the metal parts of the bus body and the battery box, thereby improving the electrical safety of the battery module; in addition, the protrusion is conducive to achieving effective insulation isolation between the positive output terminal, the negative output terminal and the battery box.

[0018] In one possible implementation, the protrusion includes a first protrusion and a second protrusion. The projection of the first protrusion onto the reference plane is a first projection, and the projection of the positive output electrode onto the reference plane is a second projection, which is located within the range of the first projection. The projection of the second protrusion onto the reference plane is a third projection, and the projection of the negative output electrode onto the reference plane is a fourth projection, which is located within the range of the third projection. The reference plane is a plane perpendicular to the height direction of the busbar.

[0019] Based on the above technical means, the protrusions of the insulating sheet can achieve full coverage of both the positive and negative output poles, thereby effectively ensuring the insulation effect.

[0020] In one possible implementation, the battery module further includes a first output busbar and a second output busbar, one end of the first output busbar being connected to the positive output terminal and one end of the second output busbar being connected to the negative output terminal, and the other ends of the first output busbar and the other ends of the second output busbar extending away from each other along a first direction.

[0021] Based on the above technical means, the design of keeping the first output busbar and the second output busbar far apart can significantly increase the air gap and creepage distance between them, effectively reduce the risk of short circuit, and avoid mutual interference between them.

[0022] In one possible implementation, the insulating base is a thermoformed base.

[0023] Based on the above-mentioned technical means, the vacuum forming process is beneficial to achieve precise shaping of the insulating base in order to meet the functional requirements of the busbar.

[0024] According to the second aspect of this application, this application provides a battery device, which includes the aforementioned battery module and battery housing, with the battery module disposed within the battery housing.

[0025] The aforementioned technical methods can help optimize the assembly process of battery devices, thereby improving the production efficiency of battery devices.

[0026] According to a third aspect of this application, this application provides a vehicle including a vehicle body and the aforementioned battery device, the battery device being disposed within the vehicle body.

[0027] The aforementioned technical methods are beneficial for improving vehicle production efficiency.

[0028] The beneficial effects of this utility model are:

[0029] (1) The battery module of this application integrates the isolation part and the main body for electrical isolation of the positive output electrode and the negative output electrode into the insulating base. In this way, while effectively ensuring electrical safety, there is no need to set up a separate output electrode insulating base, which helps to reduce the number of parts and simplify the assembly steps, thereby improving the production efficiency of the battery module.

[0030] (2) By integrating the protrusion and the sheet-like body into the insulating sheet, the insulating sheet can simultaneously achieve insulation isolation between the bus body and the battery box, as well as insulation isolation between the positive output electrode, the negative output electrode and the battery box.

[0031] It should be noted that the technical effects of the implementation methods of the second and third aspects can be found in the technical effects of the corresponding implementation methods in the first aspect, and will not be repeated here.

[0032] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0043] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0044] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0045] Next, see Figures 1-7 The battery module 100 and battery device 1000 provided in some embodiments of this application will be described in the context of a vehicle.

[0046] See Figures 1-7 In some embodiments, this application provides a battery module 100, which includes a cell assembly 7, a busbar 2, a positive output electrode 23, and a negative output electrode 24. The busbar 2 includes an insulating base 21 and a busbar body 22 disposed on the insulating base 21. The busbar body 22 is electrically connected to the cell assembly 7 and is connected to the positive output electrode 23 and the negative output electrode 24 respectively. The insulating base 21 includes a connected main body portion 211 and an isolation portion 212. The busbar body 22 is disposed on the main body portion 211. The positive output electrode 23 and the negative output electrode 24 are located at one end of the busbar body 22, and the isolation portion 212 is located between the positive output electrode 23 and the negative output electrode 24.

[0047] For ease of description, the arrangement direction of the positive output terminal 23 and the negative output terminal 24 can be defined as the first direction, the arrangement direction of the isolation part 212 and the main body part 211 can be defined as the second direction, and the arrangement direction of the busbar 2 and the cell group 7 can be defined as the third direction. The first direction can be seen as direction e1 in the figure, the second direction can be seen as direction e2 in the figure, and the third direction can be seen as direction e3 in the figure.

[0048] The battery module 100 typically includes multiple battery cells in its cell group 7. For example, the multiple cells are arranged in rows and columns to form a rectangular or cubic structure. Specifically, the multiple cells can be arranged along a second direction. Of course, the battery module 100 may also include multiple cell groups 7.

[0049] The isolation section 212 can form a physical isolation between the positive output electrode 23 and the negative output electrode 24, so as to effectively prevent contact between the positive output electrode 23 and the negative output electrode 24, and greatly improve the safety of the battery module 100.

[0050] It should be noted that the bus body 22 is the conductive part of the bus 2 and can be connected to the battery pack 7 by welding. For example, the bus body 22 can be a copper bus or an aluminum bus, etc., and this application does not make specific limitations in this regard.

[0051] For example, the insulating base 21 can be manufactured using injection molding or vacuum forming processes.

[0052] Based on this, by integrating the isolation part 212 and the main body part 211 for electrically isolating the positive output electrode 23 and the negative output electrode 24 to form an insulating base 21, the output electrode insulating base 21 is no longer required while effectively ensuring electrical safety. This helps to reduce the number of parts and simplify the assembly steps, thereby improving the production efficiency of the battery module 100.

[0053] Optionally, the battery module 100 of the cell pack 7 also includes a module end plate 6, which is located on opposite sides of the cell pack 7. The end plates on opposite sides can apply a supporting force to multiple cells, so that the multiple cells can be stably arranged in parallel.

[0054] See Figure 2 and Figure 7 In some embodiments, the height of the isolation portion 212 is greater than the height of the main body portion 211. For example, along the height direction of the busbar 2, the isolation portion 212 protrudes to one side relative to the main body portion 211, so that the height of the isolation portion 212 is greater than the height of the main body portion 211.

[0055] It should be noted that the height direction of busbar 2 is consistent with the third direction.

[0056] Based on this, the isolation section 212 can form a physical isolation between the positive output pole 23 and the negative output pole 24, so as to effectively avoid electrical faults such as short circuits between the positive output pole 23 and the negative output pole 24.

[0057] See Figure 2 and Figure 7 In some embodiments, the isolation section 212 has a cavity.

[0058] The isolation section 212 has an internal cavity, and the isolation section 212 is a hollow structure. Compared with a solid structure, it reduces the amount of material used while maintaining a certain mechanical strength. This allows for lightweight design without sacrificing structural strength, meeting the lightweight requirements of the battery module 100.

[0059] For example, along the height direction of the busbar 2, one end face of the isolation portion 212 is coplanar with the main body portion 211. Along the second direction, the side of the isolation portion 212 facing the main body portion 211 forms an opening that communicates with the cavity.

[0060] Optionally, the wall thickness of the cavity of the insulating part 212 is the same as the wall thickness of the main body 211. This helps to ensure the overall consistency of the insulating base 21, reduces the difficulty of production and molding of the insulating base 21, and improves the molding quality of the insulating base 21.

[0061] For example, the insulating base 21 is a vacuum-formed base, and the wall thickness of the insulating portion 212 is the same as the wall thickness of the main body 211. During the vacuum forming process of the insulating base 21, the plastic sheet is heated to its softening point and then formed by vacuum or pressure. If the wall thickness of the insulating portion 212 and the main body 211 differs significantly, it may lead to inconsistent material flow and cooling rates in different areas, resulting in localized material accumulation or insufficiency, affecting the dimensional accuracy and appearance quality of the final product.

[0062] Furthermore, if the wall thicknesses of the insulating portion 212 and the main body 211 differ significantly, it can easily lead to different shrinkage rates within the insulating portion 212 and the main body 211. This can cause the insulating base 21 to warp, twist, or deform due to internal stress after demolding, severely affecting assembly accuracy and performance. Therefore, having the same wall thickness for the insulating portion 212 and the main body 211 is beneficial for improving the molding quality of the insulating base 21.

[0063] Based on this, it is beneficial to achieve a lightweight design for the insulating base 21.

[0064] See Figure 2 and Figure 7 In some embodiments, a first reinforcing groove 213 is formed on the surface of the insulating base 21. The first reinforcing groove 213 includes a first sub-groove 2131 and a second sub-groove 2132 that are continuous with each other. The first sub-groove 2131 and the second sub-groove 2132 are connected. The first sub-groove 2131 is located in the main body 211 and the second sub-groove 2132 is located in the isolation part 212.

[0065] Since the overall wall thickness of the insulating base 21 is usually small, by setting the first reinforcing groove 213, the first reinforcing groove 213 can effectively disperse the concentrated stress, which is beneficial to strengthening the structural strength of the connection area between the isolation part 212 and the main body part 211.

[0066] Based on this, the structural strength and rigidity of the entire insulating base 21 can be improved without significantly increasing the weight, and the connection area between the isolation part 212 and the main body part 211 can be prevented from becoming a weak area, thus avoiding damage to the insulating base 21.

[0067] See Figure 7Optionally, a second reinforcing groove 214 may also be formed on the main body 211. The second reinforcing groove 214 may be disposed on both sides of the first reinforcing groove 213 along the first direction. For example, the second reinforcing groove 214 may be formed as an arc-shaped reinforcing groove to further improve its reinforcing effect. Furthermore, at the end of the second reinforcing groove 214 near the isolation part 212 along the second direction, material reduction may be used to avoid defects such as excessive wrinkles on the end face of the insulating base 21 caused by the forming of the arc-shaped reinforcing groove.

[0068] See Figure 2 and Figure 7 In some embodiments, along the height direction of the isolation portion 212, a notch 2121 is formed on one end face of the isolation portion 212, and a reinforcing flange 2122 is formed on the other end face of the isolation portion 212.

[0069] Specifically, since the wall thickness of the insulating base 21 is usually small, providing a notch 2121 on one end face of the isolation portion 212 helps to improve its end face strength, thereby improving the overall structural strength of the isolation portion 212. The reinforcing flange 2122 can enhance its strength and rigidity by increasing the local material thickness on the other end face of the isolation portion 212.

[0070] Based on this, the notch 2121 and the reinforced flange 2122 can enhance the structural strength of the isolation section 212.

[0071] See Figure 2 and Figure 7 Furthermore, the first reinforcing groove 213 and the notch 2121 are arranged along the second direction. This makes the overall structural strength of the insulating base 21 higher and more uniform.

[0072] See Figure 2 and Figure 7 Optionally, the notch 2121 includes a first notch 2121 and a second notch 2121 arranged along the first direction. The first notch 2121 is close to the positive output pole 23, and the second notch 2121 is close to the negative output pole 24. In this way, the first notch 2121 and the second notch 2121 can also be used to avoid the connection operation of other components and the positive and negative output poles 24.

[0073] See Figures 1-6 In some embodiments, the battery module 100 further includes an insulating sheet 1, which covers the side of the busbar 2 away from the cell assembly 7. The insulating sheet 1 includes a connected sheet-like body 11 and a protrusion 12. The sheet-like body 11 covers the busbar body 22 and the main body 211. The protrusion 12 is opposite to the positive output electrode 23 and the negative output electrode 24.

[0074] Optionally, the insulating sheet 1 can be a plastic film or a ceramic sheet, etc. Through the cooperation of the protrusion 12 and the isolation portion 212 of the insulating sheet 1, effective insulation protection can be formed in multiple positions of the positive output pole 23 and the negative output pole 24.

[0075] Optionally, the insulating sheet 1 can be bonded to the side of the busbar 2 away from the battery cell assembly 7 by means of an adhesive layer.

[0076] When the battery module 100 is applied to the battery device 1000, the battery device 1000 includes a battery housing, the battery module 100 is disposed in the battery housing, some battery housings may include metal parts, and the insulating sheet 1 can form an effective insulating protection between the battery housing and the busbar 2.

[0077] Based on this, the insulating sheet 1 can provide electrical isolation protection, and the sheet-like body 11 can prevent short circuits between the bus body 22 and the metal parts of the battery box, thereby improving the electrical safety of the battery module 100. In addition, the protrusion 12 is conducive to achieving effective insulation isolation between the positive output terminal 23, the negative output terminal 24 and the battery box.

[0078] In addition, the protrusion 12 and the sheet-like body 11 are integrated into one piece, so that there is no need to set up a separate component for insulating the positive and negative output poles 24 and the battery box in the height direction of the busbar 2. This also helps to further reduce the number of components and simplify the assembly steps.

[0079] See Figures 1-6 In some embodiments, the protrusion 12 includes a first protrusion 121 and a second protrusion 122. The projection of the first protrusion 121 onto the reference plane is a first projection, and the projection of the positive output electrode 23 onto the reference plane is a second projection, which is located within the range of the first projection. The projection of the second protrusion 122 onto the reference plane is a third projection, and the projection of the negative output electrode 24 onto the reference plane is a fourth projection, which is located within the range of the third projection. The reference plane is a plane perpendicular to the height direction of the busbar 2.

[0080] Based on this, the protrusion 12 of the insulating sheet 1 can fully cover the positive output pole 23 and the negative output pole 24, thereby effectively ensuring the insulation effect.

[0081] See Figures 1-6 Optionally, the first protrusion 121 and the second protrusion 122 are arranged along a first direction, and the first protrusion 121 and the second protrusion 122 are located on both sides of the isolation portion 212. The first protrusion 121 and the second protrusion 122 are spaced apart, and the spaced area between the first protrusion 121 and the second protrusion 122 is opposite to the isolation portion 212 along a third direction.

[0082] See Figure 2In some embodiments, the battery module 100 further includes a first output busbar 3 and a second output busbar 4. One end of the first output busbar 3 is connected to the positive output terminal 23, and one end of the second output busbar 4 is connected to the negative output terminal 24. The other ends of the first output busbar 3 and the second output busbar 4 extend in a first direction away from each other.

[0083] Optionally, the first output busbar 3 and the second output busbar 4 can be used to connect to electrical components outside the battery module 100, and can also be used to connect to adjacent battery modules 100 in the battery device 1000.

[0084] For example, the battery module 100 can be connected to a high-voltage box or inverter via the first output bus 3 and the second output bus 4.

[0085] Based on this, the design of keeping the first output busbar 3 and the second output busbar 4 far apart can significantly increase the air gap and creepage distance between them, effectively reduce the risk of short circuits, and avoid mutual interference between them.

[0086] See Figure 2 Optionally, the first output busbar 3 and the positive output pole 23 can be fixedly connected by bolts 10, and the second output busbar 4 and the negative output pole 24 can also be fixedly connected by bolts 10.

[0087] For example, the battery module 100 includes an insulating sheet 1, a first output busbar 3 and a second output busbar 4. During the assembly process of the battery module 100, the assembly order of the first output busbar 3 and the second output busbar 4 can be flexibly adjusted according to the assembly requirements of the production line. Finally, by covering the insulating sheet 1, the positive output electrode 23 and the negative output electrode 24 are completely isolated and insulated.

[0088] In some embodiments, the insulating base 21 is a vacuum-formed base. The vacuum forming process facilitates the precise shaping of the insulating base 21 to meet the functional requirements of the busbar 2.

[0089] See Figures 1-3 In some embodiments, this application provides a battery device 1000, which includes the battery module 100, battery housing and insulating sheet 1 described above, with the battery module 100 disposed inside the battery housing.

[0090] For example, the battery housing includes a housing base 9 and a top cover 8 disposed on top of the housing base 9, with an insulating sheet 1 disposed between the busbar 2 and the top cover 8 to form effective insulation protection between the top cover 8 and the busbar 2.

[0091] Based on the above-mentioned technical means, it is beneficial to optimize the assembly process of the battery device 1000, thereby improving the production efficiency of the battery device 1000.

[0092] See Figure 8 In some embodiments, this application provides a vehicle 200, which includes a vehicle body and the aforementioned battery device 1000, the battery device being disposed within the vehicle body. Based on this, by providing the battery device 1000, the production efficiency of the vehicle 200 can be improved.

[0093] In this application, the specific type of vehicle 200 is not specifically limited. For example, the vehicle 200 provided in this application can be an electric vehicle, a hybrid electric vehicle, or a solar-powered vehicle. Furthermore, the vehicle 200 provided in this application can also be of different forms. For example, the vehicle 200 provided in this application can be a sedan, a sport utility vehicle (SUV), or a multi-purpose vehicle (MPV).

[0094] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
