Description

Technical Field

[0001] The utility model relates to the technical field of new energy batteries, and in particular to a CCS component and a battery pack. Background Art

[0002] New energy technologies are developing rapidly in the context of today's era, among which new energy batteries are being applied to more and more scenarios. Battery packs are generally composed of components such as battery cells, buses and collection parts. After multiple battery cells are connected in sequence, a bus is set between two adjacent battery cells, and the collection part is connected to the bus. The collection part collects information such as the temperature and voltage of the battery cells and transmits it to the battery management system, and finally realizes the management and control of the battery pack. Common collection parts generally include wire harnesses and FPCs. Most of them are integrated with fuses on FPCs, which can prevent the collection circuit from short-circuiting and causing the battery cell to short-circuit during the data collection process. Therefore, FPC has high safety and can ensure the safety of battery pack use and avoid short-circuit burning of the battery pack. However, FPC corresponds to different projects and has a small scope of application. Different projects require different FPCs and have high costs. The cost of the wire harness collection part is low, it can adapt to different types of battery cells, and the manufacturing cycle is relatively short. However, when the wire harness is in use, it cannot prevent the battery cell from short-circuiting when the information collection circuit is short-circuited, so the safety of the wire harness is relatively poor.

[0003] As can be seen from the above, there is a problem in the prior art that the collection piece cannot have both low cost and safety. Utility Model Content

[0004] The main purpose of the utility model is to provide a CCS component and a battery pack to solve the problem that the collection components in the prior art cannot have both low cost and safety.

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0029] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0030] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0031] In order to solve the problem that the acquisition components in the prior art cannot have both low cost and safety, the utility model provides a CCS component and a battery pack. The battery pack includes the CCS component.

[0032] like Figure 1 and Figure 8 As shown, the CCS assembly includes an isolation plate 10, a busbar 20, a wire bar 30 and a fuse module 40. The busbar 20 is arranged on the isolation plate 10 for electrically connecting to the battery cell 50 of the battery pack. The wire bar 30 is electrically connected to the busbar 20. The fuse module 40 includes a mounting seat 41 and a fuse 42, wherein the mounting seat 41 is arranged on the isolation plate 10, and the fuse 42 is detachably mounted on the mounting seat 41, and the fuse 42 is connected in series with the wire bar 30.

[0033] By setting the mounting base 41 of the fuse module 40 on the isolation plate 10 and connecting the fuse 42 in series with the wire row 30, the safety of the CCS component is improved. When a short circuit occurs between the bus 20 and the wire row 30, the temperature of the fuse 42 is too high and it melts, thereby avoiding the short circuit of the CCS component causing the short circuit of the battery pack. The method of connecting the fuse 42 in series with the wire row 30 can make the CCS component safe at a low cost. At the same time, the wire row 30 can adapt to different types of battery cells 50 through simple adjustment, avoiding the cost increase caused by reprocessing new CCS components, so that the collection component has both low cost and safety.

[0034] like Figures 2 to 7 As shown, a clamping piece 411 is disposed on the mounting seat 41 , and the fuse 42 is clamped with the clamping piece 411 .

[0035] Specifically, the diameter of the fuse 42 is matched with the inner diameter of the clamping piece 411, so as to prevent the fuse 42 from being separated from the clamping piece 411. In the present embodiment, the fuse 42 is a structure with large ends and small middle, the middle is the main body of the fuse 42, and the two ends are the clamping parts. The clamping piece 411 is clamped with the two ends of the fuse 42, and the main body is suspended. When the fuse 42 is heated and melted, only the main body of the fuse 42 breaks and falls onto the mounting seat 41. Optionally, the mounting seat 41 is made of high temperature resistant material.

[0036] In this embodiment, there are multiple clamping members 411 , and the multiple clamping members 411 are arranged at intervals along the length direction of the mounting seat 41 .

[0037] It should be noted that after the fuse 42 is set on the mounting seat 41, it extends along the length direction of the mounting seat 41, and at least two clips are arranged at intervals along the length direction of the mounting seat 41 to facilitate the clipping of the fuse 42. Specifically, a plurality of clips 411 are arranged at intervals on the mounting seat 41, and the clipping of the plurality of clips 411 makes the installation and fixation of the fuse 42 more reliable. The manner in which the plurality of clips 411 are arranged at intervals makes it easy to observe the state of the fuse 42, and to observe whether the fuse 42 has artificial damage during assembly, so as to facilitate timely replacement and reduce the rework rate. Furthermore, at least two of the plurality of clips 411 are located at both ends of the mounting seat 41, respectively.

[0038] In the present embodiment, the clamping member 411 is a claw. Specifically, one clamping member 411 includes two opposing claws. When installing, the two claws are opened and the fuse 42 is then placed. Furthermore, there are two clamping members 411. The two clamping members 411 are integrally formed with the mounting seat 41 and are respectively located at the two ends of the mounting seat 41. The fuse 42 is fixed by the two clamping members 411. In the present embodiment, the clamping member 411 has a certain elasticity. Optionally, the clamping member 411 and the mounting seat 41 are injection molded structures. In other possible implementations, the clamping member 411 is a clamping hoop, which is detachably connected to the mounting seat 41 by screws. The fuse 42 is first placed on the mounting seat 41, and then the clamping hoop is buckled on the mounting seat 41. The two clamping members respectively define the two ends of the fuse 42. Of course, the clamping member 411 can also be other structural forms, which can be selected according to actual needs.

[0039] In this embodiment, there are two fuses 42 , which are arranged at an interval. One of the two fuses 42 is connected in series with the wire row 30 , and the other is a spare fuse.

[0040] Specifically, in this embodiment, two fuses 42 form a group, and one fuse module 40 includes a group of fuses 42. Correspondingly, one fuse module 40 includes two mounting seats 41. The two mounting seats 41 can be arranged in parallel or at intervals along the length direction of the isolation plate 10. They can be reasonably arranged according to the space on the isolation plate 10. When the working fuse 42 is blown, the maintenance personnel can directly replace the spare fuse 42 after eliminating the factors causing the fuse 42 to break. Among them, the length direction of the isolation plate 10 refers to the stacking direction of the battery cells 50.

[0041] In other possible embodiments, a fuse module 40 may also include a mounting base 41, two fuses 42 are arranged on the mounting base 41, and the two fuses 42 are arranged at intervals along the width direction of the mounting base 41. The mounting base 41 is provided with multiple groups of clips 411 along the width direction, and each fuse 42 corresponds to a group of clips 411, and each group of clips 411 is provided with multiple clips 411 along the length direction of the mounting base 41, thereby fixing the fuse 42.

[0042] In this embodiment, there are multiple fuse modules 40 and bus bars 20, and the wire row 30 includes multiple wires. The fuse modules 40, bus bars 20 and wires correspond one to one, wherein one end of the wire is connected to the bus bar 20 and connected in series with the fuse 42 of the fuse module 40, and the other end of the wire is used to connect to the adapter 60.

[0043] Specifically, there are multiple battery cells 50, and adjacent battery cells 50 are connected by a bus 20. Multiple bus bars 20 are connected to multiple wires in a one-to-one correspondence. One end of the multiple wires is connected to the multiple bus bars 20, and the other end is connected to the adapter 60. The data transmitted by the multiple wires is connected to the battery management system through the adapter 60, and the data signal collected by the wire bus 30 is transmitted to the battery management system through the adapter 60, so that the battery management system can monitor the entire battery pack.

[0044] Furthermore, multiple fuse modules 40 are arranged at intervals on the isolation plate 10, multiple wires correspond to multiple fuse modules 40, and one wire corresponds to at least one fuse module 40. Optionally, one wire is connected to one fuse module 40, and at least one spare fuse module is arranged near the wire. When the fuse module 40 connected to the wire is disconnected due to a large current, the spare fuse module near the wire is connected to the wire.

[0045] In this embodiment, the fuse 42 and the wire row 30 are connected by at least one of welding, crimping and plugging.

[0046] Specifically, the parts of both ends of the fuse 42 that extend beyond the mounting base 41 are connection ends. The fuse 42 is connected in series with the wire row 30, which means that the wires in the wire row 30 are disconnected, and the disconnected parts are connected to the connection ends. The use of welding and crimping can reduce processing time and improve assembly efficiency. In an undisclosed embodiment of the present application, a connector is provided at the connection end, and the wire is connected to the fuse 42 through the connector. This method is more convenient during installation and replacement, and is simple to operate.

[0047] In this embodiment, the mounting seat 41 is detachably connected to the isolation plate 10. For example, the mounting seat 41 and the isolation plate 10 are connected by bolts.

[0048] In other possible embodiments, the mounting base 41 can be bonded to the isolation plate 10. This method does not require the setting of additional structures for simple assembly. The bonding method is to set structural glue at the bottom of the mounting base 41, and place the clip 411 on the isolation plate 10 by holding it tightly. Furthermore, in order to prevent the fuse module 40 from moving after installation, the mounting base 41 is connected to the isolation plate 10 by screws to ensure the firmness of the installation of the fuse module 40.

[0049] In an optional embodiment, the mounting seat 41 and the isolation plate 10 are integrally formed.

[0050] In this embodiment, the isolation plate 10 is an injection molded plate or a vacuum molded plate.

[0051] Specifically, when the isolation plate 10 is an injection molding structure, the mounting seat 41 is integrally formed with the isolation plate 10. In order to further fix the wires of the wire row 30 to reasonably arrange the layout of the wire row 30, a plurality of slot rows are arranged at intervals along the width direction of the isolation plate 10. Each slot row is provided with a plurality of slots. The slots of the slot row are arranged at intervals along the length direction of the isolation plate. Each wire corresponds to a slot row, and the wire is fixed by the slot in the slot row. By arranging the wire in the slot, the direction and layout of the wire can be reasonably planned, so that the routing of the CCS component is reasonable and interference caused by cluttered lines can be avoided. Furthermore, a plurality of avoidance holes are also provided on the isolation plate 10 for avoiding the poles and explosion-proof valves of the battery cell 50. In some possible implementation methods, the isolation plate 10 can be set as one piece or two pieces, and the two isolation plates 10 are respectively located on both sides of the explosion-proof valve of the battery cell 50. Furthermore, the isolation plate 10 can be an injection molded plate or a blister plate. The structural quality of the injection molded plate will be better, and there will be no uneven thickness and burrs, but the processing cycle is relatively long. During the production of blister plates, multiple injection molded plates can be produced from one mold. The production cycle is relatively short, but the quality varies. A reasonable choice can be made according to actual needs.

[0052] The utility model also provides a battery pack, comprising the above-mentioned CCS component.

[0053] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: by setting the CCS assembly including the isolation plate 10, the bus bar 20, the wire bar 30 and the fuse module 40, the bus bar 20 is arranged on the isolation plate 10, and is used to be electrically connected to the battery cell 50 of the battery pack, the wire bar 30 is electrically connected to the bus bar 20, the fuse module 40 includes a mounting seat 41 and a fuse 42, the mounting seat 41 is arranged on the isolation plate 10, the fuse 42 is detachably mounted on the mounting seat 41, and the fuse 42 is connected in series with the wire bar 30, and the mounting seat 41 of the fuse module 40 is connected to the fuse module 42. The isolation plate 10 is provided with a fuse 42 in series with the wire row 30, thereby improving the safety of the CCS assembly. When a short circuit occurs between the bus bar 20 and the wire row 30, the temperature of the fuse 42 is too high and the fuse 42 is blown, thereby preventing the short circuit of the CCS assembly from causing a short circuit of the battery pack. The fuse 42 is connected in series with the wire row 30, so that the CCS assembly has both safety and low cost. At the same time, the wire row 30 can be adapted to different types of battery cells 50 through simple adjustment, thereby avoiding the cost increase caused by re-processing a new CCS assembly, so that the acquisition component has both low cost and safety.
