Description

Technical Field

[0001] The utility model relates to the field of CCS components, in particular to a CCS component. Background Art

[0002] CCS components are used in the field of electrochemical energy storage. Taking lithium-ion batteries as an example, the smallest unit of electrochemical energy storage is the battery cell, followed by a module composed of multiple battery cells, and CCS components are a common and key component of battery modules.

[0003] As a clean and efficient new energy source, electrochemical energy storage has a wide range of uses. It is used for energy storage in various types of transportation, and as backup energy or main energy source for various industries such as power plants, factories, commercial buildings, scientific research, etc. In response to the usage requirements of working conditions in different scenarios, when making energy design plans, several single cells are connected in series and parallel as needed to form a battery module, and then several battery modules are integrated with various electrical components into an energy storage box to form a battery pack for user convenience.

[0004] The so-called energy storage CCS component (integrated busbar Cells Contact System) is mainly composed of signal acquisition components (for example: FPC, FFC, PCB, etc.), copper and aluminum busbars, plastic structural parts, etc., which are integrated into a whole through riveting or hot pressing processes to realize high-voltage series and parallel connection of battery cells, as well as battery cell voltage sampling, battery temperature sampling and other functions. The voltage and temperature are collected through FPC / FFC / PCB and connector components for the BMS battery control system.

[0005] Taking lithium batteries as an example of existing electrochemical energy storage, in lithium battery modules, CCS components are very important module design parts. Usually, the voltage collection lines and temperature collection harnesses of the battery cells on the module are connected to the surface of the aluminum bar. The more battery cells there are in the module, the more voltage collection points and temperature collection points there are on the module. A large number of collection harnesses will be piled up in the limited space at the top of the module. In the face of this situation, PCB boards and FPC boards are mainly used for integrated optimization. Although PCB boards and FPC boards greatly simplify the voltage collection lines and temperature collection lines of the module battery cells, the manufacturing process is complicated and the cost is greatly increased.

[0006] If the module acquisition lines and acquisition points are not integrated and optimized using PCB or FPC boards, and traditional multi-acquisition harnesses are used for integration, the problems faced are how to securely fix the acquisition harness on the top of the entire module; how to lay out the acquisition lines neatly and beautifully; how to prevent the harness from occupying the space above each battery cell explosion-proof valve; how to quickly identify which acquisition line is faulty during after-sales maintenance, and how to quickly troubleshoot, identify, and replace it. Therefore, it is necessary to design a CCS component that is easy to sort out the harness and make the acquisition line layout neat. Utility Model Content

[0032] Furthermore, at least a portion of the connecting plate 8 is provided with two welding positions respectively welded to two battery cell poles, and the connecting plate 8 is bent between the two welding positions so as to form a "J" shape.

[0033] Furthermore, the connecting plate 8 is provided with a nickel sheet 10 which is bent into a "X" shape. A nickel sheet mounting hole 81 is provided on the connecting plate 8.

[0035] Furthermore, the connecting plate mounting groove 6 is provided with a locking protrusion 62 on at least two groove walls in the length direction, which is used to clamp the two ends of the connecting plate 8 in the length direction between the locking protrusion 62 and the groove bottom of the connecting plate mounting groove 6, and the top surface of the locking protrusion 62 is inclined downward in the direction away from the groove wall where the locking protrusion 62 is located, and the bottom surface of the locking protrusion 62 is inclined upward in the direction away from the groove wall where the locking protrusion 62 is located.

[0037] Furthermore, the cover plate 13 has buckles 14 on both sides that are perpendicular to the bottom surface of the blister plate 1. The buckles 14 cooperate with the slots 12 to fix the cover plate 13 on the blister plate 1 to cover the convex strip 5 and the two wiring grooves 4. The convex strip 5 and the cover plate 13 are both provided with explosion-proof valve clearance holes 51 through which the explosion-proof valve of the power supply core passes; the cover plate 13 is provided with a backing glue 15 at least at the position corresponding to the top surface of the convex strip 5, and is fitted with the top surface of the convex strip 5 through the backing glue 15.

[0038] Furthermore, the fastening directions of the buckles at both ends of the cover plate in the length direction are arranged in opposite directions. The buckle of this embodiment is L-shaped. In other embodiments, a double-head buckle can also be used.

[0039] Furthermore, the middle part of the top surface of the cable tie seat 7 is concave to form a harness groove 71, and the top surface of the cable tie seat 7 is provided with wire holes 72 on both sides of the harness groove 71 for the cable tie to pass through, and the height of the back of the harness groove 71 is higher than the height of the back of the wiring groove 4.

[0040] In the specific structure, the front of the blister board 1 of this embodiment is provided with two wiring grooves 4, a convex strip 5 and two rows of connecting plate mounting grooves 6. The two wiring grooves 4 are located between the two rows of connecting plate mounting grooves 6. The convex strip 5 is located between the two wiring grooves 4 to separate the two wiring grooves 4. The convex strip 5 and the two wiring grooves 4 extend along the length direction of the blister board 1. The convex strip 5 is provided with a row of explosion-proof valve clearance holes 51 for the explosion-proof valves of the power supply core to pass through. Each wiring groove 4 is provided with a plurality of wire binding seats 7. Each row of connecting plate mounting grooves 6 has a plurality of connecting plate mounting grooves 6. The wiring groove 4 is separated from an adjacent row of connecting plate mounting grooves 6 by a retaining strip 11, and the retaining strip 11 is provided with a notch for the connecting plate mounting groove 6 to connect to the wiring groove 4 at the position corresponding to each connecting plate mounting groove 6. Compared with the traditional intermediate centralized wiring arrangement, the blister board 1 of this embodiment has arranged the collection lines of the same side poles on the same side and the same road. From the structural point of view, the direction of the wiring harness is clarified, which is convenient for rapid installation, inspection and maintenance.

[0041] In the specific structure, the blocking bar 11 is provided with a notch for the connection plate installation slot 6 to connect to the wiring slot 4 at the position corresponding to each connection plate installation slot 6, that is, the groove wall of the connection plate installation slot 6 is hollowed out in the direction toward the inner side of the battery cell, and the metal connector of the signal collection line is connected to the connection plate from the notch. The electrical signal collection is placed on one side of the battery module, which is convenient for electrical connection and increases the utilization rate of the wiring space.

[0042] In the specific structure, preferably, each end of the convex strip 5 in the length direction is at a certain distance from the same end face of the blister board 1, that is, the length of the convex strip 5 is shorter than the total length of the blister board 1, so that the wire harnesses of the two wiring grooves 4 are conveniently combined into one bundle at the end of the convex strip 5. Preferably, the two ends of the convex strip 5 are set as arc end faces to avoid scratching the wire harness.

[0043] In the specific structure, the back of the blister board 1 is concave at the position of the wire tie seat 7, and the concave part is formed on the front of the blister board 1 to form the wire tie seat 7. Preferably, the top surface of the convex strip 5 and the baffle 11 is the top surface of the blister board 1, and such a design can simplify the mold used to manufacture the blister board 1. On the front of the blister board 1, the wire tie seat 7 is raised relative to the wiring groove 4 and its height is lower than the convex strip 5 and the baffle 11, that is, the wire tie seat 7 does not increase the height of the blister board 1.

[0044] The middle part of the top surface of the wire tie seat 7 is concave to form a wire harness groove 71, and the top surface of the wire tie seat 7 is provided with wire holes 72 on both sides of the wire harness groove 71 for the wire tie to pass through. The structural design of adding the wire tie seat 7 at the bottom of the blister board 1 can not only bundle the collected wire harness in the side direction on the wire tie seat 7, but also the layout of multiple wire tie seats 7 can strengthen the strength of the blister board 1.

[0045] The back of the wiring trough 4 is the back of the blister board 1, and the two are located in the same plane. Preferably, the height of the back of the harness trough 71 is higher than the height of the back of the wiring trough 4, and the height difference between the back of the harness trough 71 and the back of the wiring trough 4 is not less than the thickness of the cable tie, so that after the cable tie is added, the cable tie does not protrude from the back of the blister board 1, and is neat and beautiful.

[0046] The specific shape of the harness groove 71 is not limited, and there can be many shapes, such as an arc groove, a square groove, an elliptical groove with a notch, etc. In this embodiment, the harness groove 71 is preferably an arc groove (the arc groove should be understood in a broad sense, including a circular arc groove, an elliptical arc groove, etc.), and the bottom height of the arc groove does not affect the wire harness tie passing through the two wire holes 72 on the wire tie seat 7. The arc groove is easy to form by vacuum forming and demolding, and the wire harness is tied into a bundle with a tie. The design of the arc groove is more in line with the shape of the wire harness after being tied, making the wire harness more concentrated.

[0047] As a preferred solution, the cable holder 7 is as wide as the wiring groove, that is, the cable holder 7 is as wide as possible, so that the width of the arc groove can be increased as much as possible, reducing the influence of the cable holder 7 on the wiring harness, and preventing the wiring harness from being affected by the cable holder 7 and protruding from the top surface of the blister board 1. The cable holder 7 and the cable tie do not increase the height of the blister board 1, and the wiring harness is well fixed in the wiring groove 4. The integrated CCS component is installed on the top surface of the battery module, which does not increase the height of the module itself. Therefore, CCS improves the performance of the Pack product while not occupying the valuable internal space of the Pack box.

[0048] Adjacent connection plate mounting slots 6 in the same row are isolated by slot walls, so as to prevent each string of connection plates 8 from accidentally touching during production or use, causing a short circuit between the positive and negative electrodes of the battery cells.

[0049] Two opposite groove walls of each connecting plate installation groove 6 are provided with clamping protrusions 62, which are used to clamp the two ends of the connecting plate 8 between the clamping protrusions 62 and the groove bottom of the connecting plate installation groove 6. At least two groove walls in the length direction of the connecting plate installation groove 6 are provided with clamping protrusions 62, which are used to clamp the two ends of the connecting plate 8 in the length direction, and the clamping protrusions 62 on the two groove walls in the length direction of the connecting plate installation groove 6 are symmetrically arranged. Preferably, the top surface of the clamping protrusion 62 is inclined downward in the direction away from the groove wall where the clamping protrusion 62 is located (facilitating the connection plate 8 to be pressed down to the bottom of the clamping protrusion 62), and the bottom surface of the clamping protrusion 62 is inclined upward in the direction away from the groove wall where the clamping protrusion 62 is located (facilitating the connection plate 8 to be pulled up from the bottom of the clamping protrusion 62), that is, the top surface and the bottom surface of the clamping protrusion 62 are both inclined surfaces, which not only meets the installation limit of the connecting plate 8, but also facilitates the installation and removal of the connecting plate 8, thereby improving the pre-installation efficiency of the connecting plate 8.

[0050] Since the spacing accuracy between each connecting plate 8 is very high, any deviation may cause the welding of the connecting plate 8 and the battery cell pole surface to be offset, and the laser may skip the connecting plate 8 and directly hit the battery cell pole surface, causing the battery cell pole surface to exceed the standard melting depth and weld through the battery cell pole, so the connecting plate 8 needs to be accurately positioned. In this embodiment, at least two positioning columns 61 are provided at the bottom of each connecting plate mounting groove 6 to cooperate with the positioning holes on the connecting plate 8 for positioning. After the connecting plate 8 is inserted into the connecting plate mounting groove 6, at least two positioning columns 61 are used to assist in positioning the connecting plate 8. The positioning columns are fixed to the connecting plate by hot riveting, the two ends of the connecting plate are clamped by the clamping protrusions 62, and the connecting plate is limited by the groove wall around it, which ensures the accurate positioning of the connecting plate 8 and maintains the accuracy and stability of the position.

[0051] The connection plate installation groove 6 of this embodiment is a square groove (not strictly in square shape, but slightly adjusted according to the specific shape of the connection plate 8), the groove wall of the connection plate installation groove 6 limits the connection plate 8 on all sides, the side wall of the blocking bar 11 is a part of the groove wall of the connection plate installation groove 6, and the blocking bar 11 has a limiting effect on the side of the connection plate 8. The two ends of the connection plate 8 are clamped by the clamping protrusions 62, and the positioning column 61 positions the connection plate 8. The connection plate 8 can be pre-installed before welding to achieve pre-positioning of the welding points of the CCS component, so that the welding points of the two components are automatically aligned after the assembly is installed with the battery module. After alignment, the module laser welding process is directly entered, and direct welding is performed to improve the welding efficiency of the battery module, thereby improving the pack grouping efficiency.

[0052] Each connecting plate mounting groove 6 is provided with a through hole at the bottom to allow the pole of the power core to pass through and connect to the connecting plate 8. The blister plate 1 is made into an avoidance hole for the pole, which is convenient for connecting the connecting plate 8 and the battery core.

[0053] The blister board 1 is provided with a cover plate 13, and preferably, the length of the cover plate 13 is not less than the convex strip 5. The blister board 1 is provided with two rows of slots 12, which are respectively provided on the baffles 11 on both sides of the convex strip 5, and the baffles 11 are formed by the depression of the back of the blister board 1. The cover plate 13 is parallel to the bottom surface of the blister board 1, and the cover plate 13 has buckles 14 on both sides perpendicular to the bottom surface of the blister board 1. The buckles 14 cooperate with the slots 12 to fix the cover plate 13 on the blister board 1 to cover the convex strip 5 and the two wiring grooves 4. The buckles 14 are accommodated in the grooves corresponding to the baffles 11 on the back of the blister board 1, and the height of the baffles 11 is used to accommodate the buckles 14, so that the buckles 14 do not protrude from the bottom surface of the blister board 1.

[0054] The cover plate 13 is provided with an explosion-proof valve clearance hole 51 corresponding to the explosion-proof valve clearance hole 51 on the convex strip 5, and the cover plate 13 is provided with a backing adhesive 15 at least at the top surface position corresponding to the convex strip 5. The cover plate 13 itself is designed with a positive and negative two-way buckle 14 and a local backing adhesive 15 to assist in the installation of the cover plate 13 on the blister plate 1, so as to achieve the encapsulation of each collection harness and avoid the harness being exposed. Compared with the existing CCS solutions of the same type, this solution adds a cover plate 13, so that the scattered collection wires can be removed from the battery box cover, and the module level can better display the status of the module, which is more neat and beautiful. At the same time, the harness also has an extra layer of protection to prevent the damage to the collection harness by objects dropped during the process or maintenance.

[0055] The cover plate 13 has the following advantages:

[0056] The cover plate 13 is combined with the blister plate 1 by means of a buckle 14 + adhesive 15. The buckle 14 makes it easier to disassemble and easier for production and maintenance personnel to operate. The adhesive 15 is used at the edge of the wire harness cover plate 13 to prevent the wire harness cover plate 13 from warping, making the overall combination good, and easy to use and beautiful. The cover plate 13 also has an explosion-proof valve avoidance structure, which does not affect the performance of the explosion-proof valve.

[0057] The connection plate 8 in this embodiment includes various objects with electrical circuit connections, such as copper blocks and aluminum bars.

[0058] As a preferred design, a countersunk hole 9 is provided on the front side of each connecting plate 8 at the position corresponding to the battery cell pole, so as to control the flow direction of the welding solution during welding of the connecting plate 8 and the pole to be limited to the designed countersunk hole 9 area, thereby avoiding turbulence of individual welding solutions caused by other problems.

[0059] The assembly process of the CCS component is:

[0060] 1. Place the connecting plate 8 into the corresponding connecting plate installation groove 6 on the blister plate 1 for hot pressing, and hot melt the positioning column 61 in the connecting plate installation groove 6 to firmly fix the connecting plate 8 in the connecting plate 8 groove.

[0061] 2. Weld the module temperature and voltage collection lines to the nickel sheet 10 installed on the connecting plate 8 respectively.

[0062] 3. Arrange the temperature collection wire and voltage collection wire of the pole on the same side of the module together and tie them with a cable tie. When tying each cable tie, pass the cable tie through the wire hole 72 of the cable tie seat 7 of the blister board 1 to fix the whole bundle of collection wires on the cable tie seat 7 of the blister board 1. Do the same on the other side.

[0063] 4. After welding, arranging, bundling and fixing the collection harnesses on both sides, install the cover plate 13 on the blister plate 1.

[0064] 5. Install the cover 13 on the blister board 1: first tear off the adhesive 15 on the back of the cover 13; slightly arch the C cover 13; from one end of the cover to the other, insert the buckles 14 into the slots on the blister board 1 one by one, and then smooth the top of the cover 13 so that the adhesive 15 is firmly attached to the blister board 1.

[0065] Through the above 5 steps, the whole set of CCS is integrated. In this state, it enters the battery module process, and then enters the module connection row 2 welding process to complete the welding of the whole set of CCS on the module, so that the module changes from a semi-finished module to a finished module, which can be directly put into the pack box.

[0066] This CCS component has the following features:

[0067] 1. For the PCB board structure, since the PCB board is too hard, its ability to resist battery cell expansion and Pack anti-vibration performance is poor, and the FPC is relatively expensive. Therefore, from the perspective of reducing costs, the wiring harness + CCS method, although it has some shortcomings, it is not without advantages. In addition to low-cost, non-hardened collection harnesses, it has better flexibility to adapt to anti-battery cell expansion and vibration testing, and will not break.

[0068] 2. The blister plate 1 structurally realizes convenient installation and precise positioning of the connecting row 2 through the convex protrusions 62 and the positioning columns 61 on the blister plate 1 , and the hot pressing process enables the connecting row 2 to be firmly adsorbed on the blister plate 1 .

[0069] 3. Under the premise of lower cost, compared with the traditional wire harness fixation, usually all the collection wire harnesses on a single module are bundled together and then fixed with tape. This solution adopts a decentralized method, and the collection wire harnesses on the same side are one strand, which is firmly fixed on the wire binding seat 7 of the blister board 1.

[0070] 4. The cover plate 13 is designed with a two-way snap-on 14 + auxiliary adhesive 15, which makes installation by the production line operator easy and can prevent it from falling off in the later long-term use conditions.

[0071] 5. The design of the cover plate 13 not only realizes the encapsulation of the collection harness, but also does not affect the heat dissipation of the connecting row 2, making the single module more beautiful and covering the collection harness.

[0072] 6. Compared with the traditional blister plate 1, which is often limited to hot pressing to fix the connecting row 2, this solution uses the buckle 14 + hot pressing + positioning column 61 to install the connecting row 2. The limit of the connecting row 2 on the blister plate 1 is 360° in all directions. During the turnover process, the module may tilt or flip. At this time, the blister plate 1 of this solution can ensure that the aluminum row does not fall off, avoiding the aluminum row falling off and falling on other battery core aluminum rows, causing module short circuit, spontaneous combustion and explosion and other safety accidents;

[0073] 7. Compared with the traditional centralized wiring arrangement, the CCS solution arranges the collection lines of the poles on the same side in the same route. From the structural point of view, the direction of the wire harness is clarified, which is convenient for installation, inspection and maintenance. At the same time, a special wire harness tie seat 7 structure is made for the wire harness on the same side for bundling and fixing the wire harness. In addition, the CCS wiring method of the same route on the same side better avoids the explosion-proof space required by the explosion-proof valve, avoids the explosion-proof failure caused by the accumulation of wire harnesses on the protective film of the explosion-proof valve, and avoids the accumulation of wire harnesses, causing the explosion-proof valve protective film to fall off or be damaged, so that the explosion-proof valve loses the outermost layer of protection.

[0074] 8. Compared with similar solutions, this solution adds a wiring harness sealing plate, so that the scattered collection lines can be removed by removing the battery box cover, and the module status can be better displayed at the module level, which is more neat and beautiful. At the same time, the wiring harness also has an extra layer of protection to prevent the collection harness from being damaged by objects dropped during the process or maintenance. The wiring harness sealing plate is combined with the blister plate 1 in the form of a buckle 14 + adhesive 15. The buckle 14 method is more convenient to disassemble and easier to operate for production and maintenance personnel. Adhesive 15 is used on the edge end of this wiring harness sealing plate to prevent the wiring harness sealing plate from warping. The overall combination is easy to use and beautiful. The wiring harness sealing plate also has an explosion-proof valve avoidance structure, which does not affect the performance of the explosion-proof valve.

[0075] 9. Compared with similar output connecting plates 8, which are more straight, at least part of the connecting plates 8 used to connect two cells in this solution are bent. Specifically, the middle part of the connecting plate 8 is bent so that the connecting plate 8 is in a "F" shape. The two positions for welding with the cell poles are located on both sides of the bent part. This structure can better transfer the torque and force of the screw tightening received by the cell poles at the output end to avoid stress on the poles and the welds between the connecting plate 8 and the poles. Avoid tearing of the welds, resulting in poor contact between the total positive and total negative, generating a lot of heat, and causing safety hazards such as spontaneous combustion of the module.

[0076] 10. Compared with PCB and FPC, this CCS component greatly reduces the manufacturing cost of the module, and at the same time, it also avoids the disadvantages of the scattered line collection method to the greatest extent.

[0077] 11. The connection row 2 on the blister board 1 has a sink hole 9 at all welding points with the battery pole, which is convenient for controlling the flow direction of the welding solution when welding the connection board 8 and the pole to be limited to the designed sink hole 9 area, avoiding turbulence caused by other problems of individual welding solutions. In addition, the nickel sheet 10 is nested in the square through hole on the connection board 8, which is convenient for pre-welding of the nickel sheet 10.

[0078] The connection bar 2 in this embodiment includes various objects having electrical circuit connections, such as copper bars and aluminum bars.
