Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to side-mounted cell modules, battery boxes, and electrical equipment. Background Technology

[0002] Electric vehicles utilize batteries as their power source. Compared to gasoline-powered vehicles, electric vehicles offer advantages such as lower cost, greater convenience, and environmental friendliness. With increasing environmental awareness, the development of new energy vehicles has been rapid. As electric vehicles continue to evolve, manufacturers are focusing on improving battery range and integration efficiency to capture market share. To monitor battery voltage and temperature during operation, battery modules typically incorporate data acquisition mechanisms.

[0003] In existing technologies, a portion of the acquisition structure is welded to the positive and negative terminals of the battery to acquire the status of a single battery. However, when welding the acquisition structure to the positive and negative terminals of the battery, the acquisition structure is prone to shaking and is not easy to align with the positive and negative terminals of the battery, resulting in low operating efficiency and increased operating costs. Utility Model Content

[0004] This application provides a side-mounted battery cell module, battery box, and electrical equipment, which can improve operating efficiency and reduce operating costs.

[0005] The first aspect of this application provides a side-mounted battery cell module, including a battery cell assembly, a data acquisition structure, a mounting frame, and a support. The battery cell assembly has multiple battery cell units arranged along a first direction. The data acquisition structure has an information acquisition unit corresponding to the electrode of each battery cell unit. The mounting frame and the support are disposed around the periphery of the battery cell assembly. The data acquisition structure is connected to the support, and the support is detachably connected to the mounting frame. A limiting space is provided between the support and the mounting frame to define the position of the battery cell assembly. When the support is connected to the mounting frame, the battery cell assembly can be defined within the limiting space, and the information acquisition unit of the data acquisition structure can correspond one-to-one with the electrode of the battery cell unit.

[0006] According to the side-mounted battery cell module described in the first aspect of this application, by detachably connecting the bracket to the fixing frame, a limited space can be formed between the bracket and the fixing frame to restrict the movement of the battery cell assembly in a predetermined direction. When the battery cell assembly is located in this limited space, the battery cell assembly can be fixed relative to the bracket and the fixing frame in the first and second directions. Furthermore, because the acquisition structure is connected to the bracket, when the bracket and the fixing frame are connected, the acquisition structure and the battery cell assembly can be relatively fixed, ensuring that the information acquisition part of the acquisition structure corresponds one-to-one with the corresponding electrode and remains in a fixed position. This guarantees the stability of the welding between the acquisition structure and the battery cell assembly, increases welding efficiency, and reduces operating costs.

[0008] In one possible implementation, the mounting bracket is provided with a protrusion, and the bracket is provided with a hanging hole corresponding to the position of the protrusion, the protrusion being able to be inserted into the hanging hole.

[0009] In one possible implementation, the mounting bracket includes two fixing portions spaced apart along a first direction, the battery cell assembly is located between the two fixing portions, and the bracket includes a frame plate with both ends connected to the fixing portions.

[0010] In one possible implementation, the acquisition structure includes a plurality of acquisition plates forming the information acquisition part of the acquisition structure. The acquisition plates are detachably connected to the frame plate. When the frame plate and the fixing frame are connected, the acquisition plates face the electrodes of the battery cell unit.

[0011] In one possible implementation, the frame plate is provided with a receiving hole, and the frame plate is also provided with a positioning structure located in the receiving hole, the collection bar can be received in the receiving hole, and the positioning structure can fix the collection bar in the receiving hole.

[0012] In one possible implementation, the positioning structure includes a limiting member and a positioning member, the limiting member and the positioning member being spaced apart, and the acquisition bar can be confined within the gap between the limiting member and the positioning member.

[0013] In one possible implementation, the support further includes a base disposed at one end of the frame plate, at least one of the sampling pads being disposed close to the base, and the sampling pad close to the base having a bend that can be accommodated in the base.

[0014] In one possible implementation, the base includes a seat body and a protective cover connected to the seat body, the seat body being integrally formed on the frame plate, a protective space being provided between the seat body and the protective cover, and the bent portion being accommodating the protective space.

[0015] In one possible implementation, the frame plate is provided with a plurality of receiving holes, which are spaced apart along a first direction.

[0016] In one possible implementation, the acquisition structure further includes an output component connected to the frame plate, the output component having an output end, and the output component and the acquisition plate being connected via a sampling component.

[0017] In one possible implementation, the shelf plate is further provided with a placement slot, into which the output component can be adapted.

[0018] In one possible implementation, the bracket further includes a support portion disposed on the frame plate, and the output end is connectable to the support portion.

[0019] In one possible implementation, at least two brackets are provided, spaced apart along a second direction perpendicular to the first direction, with the battery pack sandwiched between the two brackets, and a data acquisition structure connected to each bracket.

[0033] Electric vehicles are equipped with a battery box that supplies power to the vehicle. The battery box can house multiple battery modules, and each battery module can contain multiple battery cells. Each battery module also has a data acquisition structure with copper plates that connect to the electrodes of the battery cells. These copper plates collect information such as voltage and temperature from the battery cells. Typically, when multiple battery cells are stacked together in a predetermined direction, welding equipment is used to weld the copper plates from the data acquisition structure to the electrodes of the corresponding battery cells.

[0034] In related technologies, there is no positioning structure for locating the acquisition structure. This easily leads to several problems. For example, the copper sheet of the acquisition structure may not align with the corresponding electrode, or the acquisition structure may wobble or tilt during welding, causing subsequent welding position deviations. These problems in related technologies can all lead to welding errors between the acquisition structure and the battery electrodes. Welding errors require re-welding, thus reducing welding efficiency and increasing operating costs due to repeated work.

[0035] This application provides a side-mounted battery cell module to address the above-mentioned problems. The side-mounted battery cell module includes multiple battery cells and a data acquisition structure. Before the electrodes of the data acquisition structure and the battery cells are welded, the data acquisition structure can be fixed relative to the battery cells, so that the position to be welded between the data acquisition structure and the battery cells is not easily shifted, ensuring the accuracy of welding, increasing welding efficiency, and reducing operating costs.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] This application provides a side-mounted battery cell module for use in a battery box. The side-mounted battery cell module includes a battery cell assembly 10, a fixing frame 20, a data acquisition structure 30, and a support 40.

[0038] For ease of description, see Figure 1 As shown, the first direction is defined as the X direction, the second direction as the Y direction, and the third direction as the Z direction. For example, the length direction of the battery cell assembly 10 is the X direction, the height direction of the battery cell assembly 10 is the Z direction, and the width direction of the battery cell assembly 10 is the Y direction.

[0039] Specifically, see Figure 1 As shown, the battery cell assembly 10 is used to provide electrical energy, and the battery cell assembly 10 has multiple battery cell units 11 arranged along a first direction. The acquisition structure 30 is provided with an information acquisition unit for each electrode of the battery cell unit 11. In the battery cell module manufacturing process, the information acquisition unit and the electrode of the battery cell unit 11 need to be welded together in order to acquire information such as voltage or temperature of the battery cell unit 11.

[0040] Both the fixing frame 20 and the bracket 40 are disposed on the periphery of the battery cell assembly 10. A portion of the bracket 40 is detachably connected to the fixing frame 20, and a defined space is formed between the bracket 40 and the fixing frame 20, allowing the battery cell assembly 10 to be confined within this space. It should be noted that the periphery of the battery cell assembly 10 refers to its sides in the first and second directions. Therefore, the cooperation between the fixing frame 20 and the bracket 40 restricts the movement of the battery cell assembly 10 within the plane formed by the first and second directions.

[0041] The acquisition structure 30 is connected to the bracket 40. When the bracket 40 is connected to the fixed frame 20, the battery cell group 10 is confined within a confined space, and the information acquisition part of the acquisition structure 30 can correspond one-to-one with the electrodes of the battery cell unit 11. At this time, the position of the acquisition structure 30 relative to the battery cell unit 11 is fixed.

[0042] By detachably connecting the bracket 40 to the fixing frame 20, a limited space can be formed between the bracket 40 and the fixing frame 20 to restrict the movement of the battery cell assembly 10 in a predetermined direction. When the battery cell assembly 10 is located in this limited space, it can be fixed relative to the bracket 40 and the fixing frame 20 in the first and second directions. Furthermore, because the acquisition structure 30 is connected to the bracket 40, when the bracket 40 and the fixing frame 20 are connected, the acquisition structure 30 and the battery cell assembly 10 can be relatively fixed, ensuring that the information acquisition part of the acquisition structure 30 corresponds one-to-one with the corresponding electrode and remains in a fixed position. This guarantees the stability of the welding between the acquisition structure 30 and the battery cell assembly 10, increases welding efficiency, and reduces operating costs.

[0043] See also some of the possible implementation methods. Figure 1 and Figure 2As shown, there are multiple ways to connect the fixing frame 20 and the bracket 40. For example, the fixing frame 20 and the bracket 40 can be connected by a snap-fit ​​structure, or they can be connected by a fastening structure, or they can be connected together by screws.

[0044] For example, the fixing frame 20 and the bracket 40 can be connected together by one of the above-described connection methods, or they can be connected together by a combination of the above-described connection methods.

[0045] For example, when the fixing frame 20 and the bracket 40 are connected, a defined space is provided, and the shape and size of the defined space need to be adapted to the external dimensions of the battery cell assembly 10.

[0046] By making the fixing bracket 20 and the support bracket 40 detachable, it is convenient to install, remove and replace them.

[0047] In some feasible implementations, the mounting bracket 20 is provided with a protrusion 21, and the support 40 is provided with a hanging hole 411 corresponding to the position of the protrusion 21, so that the protrusion 21 can be inserted into the hanging hole 411. The support 40 can be detachably connected to the mounting bracket 20 through the cooperation of the protrusion 21 and the hanging hole 411.

[0048] For example, in order to stabilize the relative position between the bracket 40 and the fixing frame 20, a plurality of spaced protrusions 21 are provided on the fixing frame 20, and a hanging hole 411 is provided on the bracket 40 corresponding to the position of each protrusion 21. The plurality of protrusions 21 and the plurality of hanging holes 411 correspond one-to-one, which can make the relative position between the fixing frame 20 and the bracket 40 relatively stable.

[0049] In other possible implementations, the protrusion 21 can also be provided on the bracket 40, and a hanging hole 411 can be provided at the corresponding position of the fixing bracket 20.

[0050] In some possible implementations, the mounting bracket 20 includes two mounting portions 22 spaced apart along a first direction, with the battery cell assembly 10 located between the two mounting portions 22. The battery cell assembly 10 has two side ends along the first direction and two side ends along a second direction, wherein the second direction is perpendicular to the first direction. The two mounting brackets 20 are respectively located on the two side ends of the battery cell assembly 10 along the first direction.

[0051] It should be noted that when welding the electrodes of the battery cell unit 11 to the acquisition structure 30, external equipment is needed to clamp the fixing frame 20 and the battery cell assembly 10 in the first direction to ensure that the position of the battery cell unit 11 is relatively stable. At this time, the fixing frame 20 will be close to the side of the battery cell assembly 10. In order to prevent the fixing frame 20 from squeezing and damaging the surface of the battery cell unit 11, a buffer is provided on the side wall of the fixing frame 20 facing the battery cell unit 11, such as a layer of silicone pad or sponge pad. The buffer is sandwiched between the fixing frame 20 and the battery cell unit 11 to buffer the squeezing of the fixing part 22.

[0052] See Figures 1 to 3 As shown, the bracket 40 of this embodiment includes a bracket plate 41, which is located between two fixed brackets 20 and is close to the side end of the battery cell assembly 10 along the second direction. The length direction of the bracket plate 41 is parallel to the first direction, and both ends of the bracket plate 41 are disposed close to the fixing part 22. At least a part of the structure of the bracket plate 41 can overlap with the fixing part 22. The fixing part 22 has a protrusion 21 at the position where it overlaps with the bracket plate 41. The bracket plate 41 has a hanging hole 411 at the corresponding position. Both fixed brackets 20 can be connected to the bracket plate 41 through the cooperation of the protrusion 21 and the hanging hole 411, so that both ends of the bracket plate 41 are respectively connected to the two fixing parts 22.

[0053] In some feasible implementations, the acquisition structure 30 includes multiple acquisition plates 33, which form the information acquisition section of the acquisition structure 30. The acquisition plates 33 can be welded to the electrodes of the battery cell unit 11. The acquisition plates 33 are connected to the frame plate 41 and can be fixedly mounted relative to the frame plate 41. When the frame plate 41 is connected to the fixing frame 20, the acquisition plates 33 face the electrodes of the battery cell unit 11.

[0054] It should be noted that one sampling plate 33 can be used to weld one electrode, so the number of sampling plates 33 needs to be determined according to the number of electrodes.

[0055] Alternatively, a single acquisition plate 33 may be provided with multiple acquisition areas. When the frame plate 41 is connected to the fixing frame 20, the multiple acquisition areas on a single acquisition plate 33 can each correspond to an electrode. In this embodiment, an example is given where a single acquisition plate 33 has multiple acquisition areas.

[0056] It is worth mentioning that the data acquisition device 33 is detachably connected to the frame plate 41. For example, a snap-fit ​​structure or a fastening structure can be provided between the data acquisition device 33 and the frame plate 41, and the two are connected by the snap-fit ​​structure or the fastening structure. Alternatively, the data acquisition device 33 can be fixedly connected to the frame plate 41 by screws. The embodiment of this application facilitates the assembly and disassembly of the data acquisition device 33 and the frame plate 41 by making them detachable, which is convenient for maintenance and repair.

[0057] In some feasible embodiments, the frame plate 41 is provided with a receiving hole 413, and the frame plate 41 is also provided with a positioning structure 412 located in the receiving hole 413. The shape and size of the receiving hole 413 are adapted to the outer dimensions of the collection plate 33, so that the collection plate 33 can be received in the receiving hole 413. When the collection plate 33 is located in the receiving hole 413, the positioning structure 412 can fix the collection plate 33 in the receiving hole 413.

[0058] For example, the receiving hole 413 is a through hole that passes through the frame plate 41. When the sampling pad 33 is located in the receiving hole 413, the surface of the sampling pad 33 can be attached to the electrode.

[0059] See Figure 1 , Figure 4 and Figure 5 As shown, in some possible implementations, the positioning structure 412 includes a limiting member 4121 and a positioning member 4122, which are spaced apart in the second direction. The edge of the sampling pad 33 can be inserted into the gap between the limiting member 4121 and the positioning member 4122, so that the sampling pad 33 is fixed relative to the battery cell unit 11 in the second direction.

[0060] Specifically, both the limiting member 4121 and the positioning member 4122 are connected to the groove wall of the receiving hole 413, and the limiting member 4121 and the positioning member 4122 protrude from the groove wall of the receiving hole 413. Multiple limiting members 4121 and multiple positioning members 4122 can be disposed within the receiving hole 413, and the multiple positioning members 4122 and multiple limiting members 4121 cooperate to form multiple gaps for fixing the acquisition plate 33. The multiple limiting members 4121 and multiple positioning members 4122 are spaced apart around the hole wall of the receiving hole 413.

[0061] For example, the positioning member 4122 includes a first positioning member 4123 and a second positioning member 4124. The positions of the first positioning member 4123 and the limiting member 4121 relative to the frame plate 41 are fixed, so that the gap between the first positioning member 4123 and the limiting member 4121 is fixed.

[0062] The second positioning member 4124 is configured as an elastic member. One end of the second positioning member 4124 is fixedly connected to the frame plate 41, and the other end is provided with a snap-fit ​​part 41241. The frame plate 41 is provided with a relief groove 415 communicating with the receiving hole 413 at the position corresponding to the second positioning member 4124. In the free state, the snap-fit ​​part 41241 of the second positioning member 4124 can extend into the receiving hole 413 through the relief groove 415, and a gap can be formed between the snap-fit ​​part 41241 of the second positioning member 4124 and the limiting member 4121 to limit the position of the collection bar 33.

[0063] It should be noted that the first positioning member 4123 and the second positioning member 4124 are disposed opposite to each other on the opposite side of the receiving hole 413, which enables the opposite ends of the collection plate 33 to be fixed. For example, in the embodiment of this application, the first positioning member 4123 and the second positioning member 4124 are disposed on both sides of the receiving hole 413 along the third direction.

[0064] In this embodiment, when it is necessary to fix the collection pad 33 in the receiving hole 413, one edge of the collection pad 33 can be first inserted into the gap between the first positioning member 4123 and the limiting member 4121. Then, the other edge of the collection pad 33 is moved toward the gap between the second positioning member 4124 and the limiting member 4121. After moving to a certain extent, the edge of the collection pad 33 can abut against the locking part 41241. At this time, by squeezing the locking part 41241, the second positioning member 4124 can be forced to abut against the locking part 41241. When the positioning member 4124 undergoes elastic deformation, the locking part 41241 retracts into the relief groove 415, thereby allowing the sampling bar 33 to smoothly abut against the limiting member 4121. When the sampling bar 33 enters the gap between the locking part 41241 and the limiting member 4121, the locking part 41241 springs back into the receiving hole 413 under elastic action. In this way, the end of the sampling bar 33 away from the first positioning member 4123 can be locked between the locking part 41241 and the limiting member 4121.

[0065] For example, in order to ensure that the collection bar 33 does not easily shake, the thickness of the edge of the collection bar 33 is set to be adapted to the size of the gap between the limiting member 4121 and the first positioning member 4123 and the limiting member 4121 and the snap-fit ​​part 41241.

[0066] In this embodiment, the limiting member 4121 is a strip-shaped structure. The length direction of the limiting member 4121 is parallel to the third direction, and the two ends of the limiting member 4121 are respectively connected to the wall of the receiving hole 413.

[0067] For example, multiple limiting members 4121 are arranged at equal intervals along a first direction. The spacing between two adjacent limiting members 4121 is consistent with the size of the corresponding collection area on the collection bar 33 in the first direction. The multiple limiting members 4121 divide the receiving hole 413 into multiple sub-regions, and the shape and size of each sub-region are adapted to the shape and size of the collection area on the collection bar 33. By setting the limiting members 4121 as strip structures and enabling the limiting members 4121 to divide the receiving hole 413 into multiple sub-regions, when the collection bar 33 is connected to the frame plate 41, the collection area can be located within the corresponding sub-region. When the electrode and the collection bar 33 are welded, the two adjacent electrodes are separated by the limiting members 4121, which is beneficial for insulating the two adjacent electrodes.

[0068] For example, the frame plate 41 is provided with a plurality of receiving holes 413 along its length direction, and each receiving hole 413 corresponds to a collection bar 33. The plurality of receiving holes 413 are spaced apart along the first direction. By providing a plurality of receiving holes 413 and spaced apart from adjacent receiving holes 413, the two adjacent collection bars 33 will not affect each other.

[0069] In some feasible ways, the bracket 40 also includes an end cap 44, which can be fixed to the bracket plate 41 by a snap-fit ​​structure, a fastening structure or by screws. The end cap 44 is specifically connected to the end of the bracket plate 41 facing away from the battery pack 10. The end cap 44 can cover the receiving hole 413 to protect the acquisition bar 33 within the receiving hole 413.

[0070] For example, the receiving hole 413 is provided with a protrusion on the side edge facing away from the battery pack 10, and the end cap 44 can abut against the protrusion structure of the receiving hole 413, so that there is a certain gap between the end cap 44 and the sampling plate 33. This can prevent the end cap 44 from directly abutting against the sampling plate 33, which is beneficial to protect the sampling plate 33 from damage.

[0071] In related technologies, the sensor strip 33 near the end of the rack plate 41 usually needs to be bent. When the sensor strip 33 is connected to the rack plate 41, the bent part of the sensor strip 33 faces the end face of the battery cell assembly 10 in the third direction. When the battery cell module is packed into a box, arcing is more likely to occur. In order to ensure the insulation of the bent part of the sensor strip 33, related technologies use heat shrink tubing or dip coating to insulate the bent part of the sensor strip 33. However, these methods of treating the bent part of the sensor strip 33 are relatively complicated and costly.

[0072] Based on this, see Figure 4 As shown in this embodiment, the bracket 40 further includes a base 42, which is fixedly connected to the frame plate 41. The base 42 is positioned near the bent portion of the sampling pad 33, and the bent portion of the sampling pad 33 can be accommodated in the base 42. By setting the base 42, the bent portion of the sampling pad 33 can be housed inside the base 42, ensuring the insulation of the bent portion when the battery cell module is placed in the box. The base 42 eliminates the need for heat shrinking and other processes to process the bent portion in related technologies, simplifying the box placement process and reducing costs.

[0073] For example, the base 42 includes a base body 421 and a protective cover 422 connected to the base body 421. The base body 421 is integrally formed on the frame plate 41, and a protective space is formed between the base body 421 and the protective cover 422, and the bent portion can be accommodated within the protective space. Through the cooperation between the base body 421 and the protective cover 422, the bent portion can be protected within the protective space.

[0074] For example, the protective cover 422 can be detachably connected to the base 421, such as by a snap-fit ​​structure, a fastening structure, or screws.

[0075] For example, when the frame plate 41 is connected to the fixed frame 20, the base 42's seat 421 can overlap the battery cell assembly 10, thereby providing support for the combined structure of the entire bracket 40 and the acquisition structure 30. Additionally, a plastic sheet can be protruded from the middle of the frame plate 41. When the frame plate 41 is connected to the fixed frame 20, the plastic sheet can overlap the upper end of the battery cell assembly 10 to prevent the middle part of the bracket 40 from sinking and causing poor welding.

[0076] See Figure 3 and Figure 4 As shown, in some possible implementations, the acquisition structure 30 also includes an output component 31, which is connected to the frame plate 41 and has an output terminal 311. The output component 31 and the acquisition bar 33 are connected via a sampling component 32. The information acquired by the acquisition bar 33 can be transmitted to the output component 31 via the sampling component 32, and the output component 31 outputs the acquired information of the battery cell unit 11 through the output terminal 311.

[0077] For example, the shelf plate 41 is also provided with a placement slot 414, and the output component 31 can be adapted into the placement slot 414. By providing the placement slot 414, a placement space can be provided for the output component 31 on the shelf plate 41, and the adaptation between the placement slot 414 and the output component 31 can define the position of the output component 31 relative to the shelf plate 41. The output component 31 and the shelf plate 41 can be connected together by a snap-fit ​​structure, a fastening structure, or screws.

[0078] For example, the output end 311 is located at the end of the output component 31, and the output end 311 has a certain bending angle relative to the output component 31 as a whole. In order to ensure that the relative angle between the output end 311 and the output component 31 is fixed, the bracket 40 also includes a support part 43, which is disposed on the frame plate 41. When the output component 31 is installed on the frame plate 41, the support part 43 is positioned directly opposite the output end 311, so that the output end 311 can be connected to the support part 43.
