Description

Technical Field

[0001] The utility model relates to the technical field of power batteries, in particular to an integrated busbar and battery module. Background Art

[0002] With the rapid development of the new energy field, especially the advancement of technologies such as electric vehicles, the space requirements for power battery packs and energy storage battery packs are becoming increasingly higher. How to design a reasonable space layout has become particularly important.

[0003] Existing integrated busbar systems (CCS) generally use a single connector placed above the battery module for signal collection. Placing a single connector above the battery module increases the height of the entire module, resulting in a less compact layout and wasted space. Furthermore, when a battery module contains a large number of soft-pack cells, the number of signal points that need to be collected increases accordingly. In this case, a single connector cannot meet the signal collection requirements.

[0004] Therefore, it is necessary to provide an integrated busbar and battery module to solve the above problems existing in the prior art. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide an integrated busbar and battery module to solve the technical problem of unreasonable spatial layout of the integrated busbar in the prior art.

[0006] In order to solve the above technical problems, the utility model provides an integrated busbar, comprising:

[0007] A bottom plate, with cutouts formed at both ends of the bottom plate;

[0008] Two support plates, the support plates covering the corresponding cutouts and enclosing a semi-open accommodating cavity together with the corresponding cutouts;

[0009] Two connectors, the connectors being fixed to the lower side of the support plate and placed in the corresponding accommodating cavities;

[0010] The signal acquisition component includes a circuit board, wherein the two ends of the circuit board are respectively connected to the corresponding support plates; and the connector is electrically connected to the circuit board.

[0011] The integrated busbar provided by the utility model has the following beneficial effects:

[0012] A cavity is formed between the cutout of the base plate and the support plate to accommodate the connector. At this time, the connector is fixed to the lower side of the support plate, and the circuit board of the signal acquisition component is placed above the support plate and the base plate. This design not only effectively reduces the overall height of the module, but also makes the overall spatial layout of the integrated busbar compact. At the same time, a connector is electrically connected at each end of the circuit board, which can still meet the signal acquisition requirements when more signal acquisition points are collected.

[0013] Preferably, the support plate is provided with a first fixing hole and a second fixing hole; the connector is provided with a snap fastener, which is inserted into the first fixing hole to fix the connector and the support plate; the base plate is provided with a first fixing post, which is inserted into the second fixing hole to fix the support plate and the base plate. This has the beneficial effect of: the snap fastener is inserted into the first fixing hole to fix the connector and the support plate, and the first fixing post is inserted into the second fixing hole to place the support plate on the base plate and form an accommodating cavity with the cutout of the base plate. At this time, the connector is placed in the accommodating cavity, thereby achieving the connection and fixation of the connector, base plate, and support plate, saving the height space of the module.

[0014] Preferably, the ends of the circuit board are provided with connection holes, and the first fixing posts are respectively inserted into the second fixing holes and the connection holes to sequentially connect the base plate, the support plate, and the circuit board. This advantageously provides connection holes at both ends of the circuit board, allowing the circuit board to be placed on the support plate and the base plate, thereby rationally planning the overall spatial layout of the integrated busbar.

[0015] Preferably, the support plate comprises a transverse plate, a first bent member, and a second bent member, with the first and second bent members connected at both ends of the transverse plate. The transverse plate covers the cutout, with the first and second bent members positioned on either side of the cutout. This advantageously provides the following advantages: the support plate structure, comprising the transverse plate, the first bent member, and the second bent member, strengthens the bottom plate when the support plate covers the cutout of the bottom plate, thereby reducing the risk of the bottom plate breaking due to prolonged vibration.

[0016] Preferably, the system further comprises a plurality of aluminum bars, the base plate being provided with a plurality of mounting slots corresponding to the aluminum bars, the mounting slots being provided with second fixing posts, and the aluminum bars being provided with mounting holes; the second fixing posts being inserted into the mounting holes for mounting the aluminum bars in the mounting slots. This advantageous effect is that by mounting the aluminum bars in the mounting slots, base plate space is conserved, and this structural design also saves height space.

[0017] Preferably, the signal acquisition assembly further includes a plurality of nickel sheets corresponding to the aluminum bars, the nickel sheets being disposed on the circuit board and connected to the aluminum bars. This advantageously allows for connection between the signal acquisition assembly and the aluminum bars and enhances the stability of the overall structure through the design of the nickel sheets.

[0018] Preferably, the nickel sheet includes a first horizontal member, a vertical member, and a second horizontal member. The vertical member is connected to the first and second horizontal members at both ends. The first horizontal member is connected to the circuit board, and the second horizontal member is connected to the aluminum bar. This advantageously provides the following advantages: because the vertical member is at a certain height relative to the second horizontal member, the signal acquisition assembly is raised as a whole, effectively increasing the width of the signal acquisition assembly. Furthermore, the second horizontal member and the aluminum bar are welded in the same position, enabling overlap welding and effectively improving welding efficiency.

[0019] The utility model also provides a battery module, comprising:

[0020] An integrated busbar as described above;

[0021] The battery cell assembly is provided with the integrated busbar.

[0022] For the beneficial effects of the battery module provided by the present invention, reference can be made to the description of the integrated busbar described above.

[0023] Preferably, the battery cell assembly further includes end plates, two of which are arranged on both sides of the battery cell assembly, and the support plate abuts against the end plates. The beneficial effect is that the support function of the entire module is strengthened by designing the support plate abutting against the end plates.

[0024] Preferably, a battery management system is further included, which is arranged on the side wall of the end plate and is electrically connected to the corresponding connector. The beneficial effect is that the battery management system is arranged on the side wall of the end plate, making the overall spatial layout of the battery module compact and reasonable.

[0041] like Figures 1-11As shown, an embodiment of the present invention provides an integrated busbar 10 comprising a base plate 1, two support plates 2, two connectors 3, and a signal acquisition assembly 4. The signal acquisition assembly 4 is used to collect battery temperature and cell voltage. The signal acquisition assembly 4 includes a circuit board 41. Both connectors 3 are electrically connected to the circuit board 41, thereby transmitting the temperature and voltage signals collected by the signal acquisition assembly 4 to the battery management system.

[0042] Both ends of the base plate 1 are provided with cutouts 11. In other words, there are two cutouts 11, and the number of cutouts 11, support plates 2, and connectors 3 corresponds one to one. The support plates 2 cover the corresponding cutouts 11 and, together with the corresponding cutouts 11, form a semi-open receiving cavity. The connector 3 is fixed to the underside of the corresponding support plate 2 and placed in the corresponding receiving cavity. The two ends of the circuit board 41 are respectively connected to the corresponding support plate 2. At this point, the circuit board 41 is placed on the two support plates 2 and the base plate 1.

[0043] By designing the accommodating cavity enclosed by the cutout 11 of the base plate 1 and the support plate 2, the connector 3 is fixed to the lower side of the support plate 2 when placed in the accommodating cavity, that is, the connector 3 is inverted, which effectively reduces the overall height of the battery module and makes the overall spatial layout design of the integrated busbar 10 reasonable and compact; and the design of two connectors 3 effectively solves the technical problem of being unable to meet the signal acquisition requirements when the number of battery cells is too large. At the same time, the two connectors 3 are electrically connected to the two ends of the circuit board 41, thereby transmitting the signals collected by the signal acquisition component 4.

[0044] Specifically, the signal acquisition component 4 is a flexible printed circuit (FPC) component. Made of polyimide or polyester film, FPC is a highly reliable and flexible printed circuit board with high wiring density, light weight, thin thickness, and good bendability.

[0045] like Figure 6-Figure 7 As shown and combined with reference Figure 9In some embodiments of the present invention, a first fixing hole 21 and a second fixing hole 22 are provided on the support plate 2. A snap fastener 31 is provided on the connector 3. The snap fastener 31 is inserted into the first fixing hole 21 to fix the connector 3 and the support plate 2. A first fixing column 12 is provided on the base plate 1. The first fixing column 12 is inserted into the second fixing hole 22 to fix the support plate 2 and the base plate 1. Through this connection method, the connector 3 is inverted, that is, the connector is placed below the support plate 2. The design of the inverted connector 3 saves the height space of the battery module. Exemplarily, the process of installing one of the support plates 2 and the connector 3 on the base plate 1 is as follows: first align the second fixing hole 22 of the support plate 2 with the first fixing column 11 of the base plate 1, so that the first fixing column 11 passes through the second fixing hole 22. At this time, the support plate 1 and the cutout 11 of the base plate 1 form a receiving cavity; then place the connector 3 in the receiving cavity, align the snap member 31 with the first fixing hole 21 of the support plate 2, and then snap it into the first fixing hole 21, thereby fixing the connector 3 and the support plate 2 to the base plate 1 together. The installation method of the other support plate 2 and the connector 3 is as described above and will not be repeated here. It should be noted that this installation sequence is only an example.

[0046] like Figure 6-Figure 7 As shown and combined with reference Figure 3 In some embodiments of the present invention, a connection hole 42 is provided at the end of the circuit board 41. The first fixing post 12 is respectively inserted into the second fixing hole 22 and the connection hole 42 to sequentially connect the base plate 1, the support plate 2, and the circuit board 41. For example, there are two connection holes 42, corresponding to two first fixing posts 12 and two second fixing holes 22. The first fixing post 12 inserted into the second fixing hole 22 is aligned with the connection hole 42 and then inserted, thereby fixing the circuit board 41 to the support plate 2. At this time, the circuit board 41 is placed on the two support plates 2 and the base plate 1.

[0047] like Figure 6 and Figure 7As shown, in some embodiments of the present utility model, the support plate 2 includes a cross plate 23, a first bending member 24, and a second bending member 25. The two ends of the cross plate 23 are respectively connected to the first bending member 24 and the second bending member 25. It should be noted that the cross plate 23, the first bending member 24, and the second bending member 25 can be either an integral structure or a split structure. The cross plate 23 covers the cut 11. It should be noted that the cut 11 is a "C"-shaped opening formed at the end of the bottom plate 1. When the cross plate 23 is placed on the upper side of the "C"-shaped opening, a semi-open receiving cavity is formed with the "C"-shaped opening to receive the connector 3. The first bending member 24 and the second bending member 25 are respectively placed on both sides of the cut 11. That is, the first bending member 24 and the second bending member 25 are clamped on both sides of the "C"-shaped opening, thereby strengthening the support strength of the bottom plate 1 and ensuring that there is no risk of fracture at the end of the bottom plate 1 during the long-term vibration of the electric vehicle.

[0048] As Figure 3-Figure 5 shown, in some embodiments of the present utility model, the integrated busbar further includes a plurality of aluminum bars 5. The bottom plate 1 is provided with a plurality of mounting grooves 13 corresponding to the aluminum bars 5. The mounting grooves 13 are provided with second fixing columns 14. The aluminum bars 5 are provided with mounting holes 51. The second fixing columns 14 pass through the mounting holes 51 to mount the aluminum bars 5 in the mounting grooves 13. Exemplarily, there are two second fixing columns 14 in each mounting groove 13, and there are also two mounting holes 51 on each aluminum bar 5. After aligning the second fixing columns 14 with the mounting holes 51 and passing them through, the aluminum bars 5 are fixed in the mounting grooves 13.

[0049] Specifically, both the first fixing column 12 and the second fixing column 14 are hot riveting columns. The bottom plate 1, the support plate 2, and the circuit board 41 are connected by using the hot riveting process, and the aluminum bars 5 are also installed in the mounting grooves 13 by using the hot riveting process.

[0050] As Figure 1-Figure 3 shown, in some embodiments of the present utility model, the signal acquisition component 4 further includes a plurality of nickel sheets 43 corresponding to the aluminum bars 5. The nickel sheets 43 are arranged on the circuit board 41 and the nickel sheets 43 are connected to the aluminum bars 5. It should be noted that the numbers of the nickel sheets 43, the aluminum bars 5, and the mounting grooves 13 are set to correspond to each other. Through the design of the nickel sheets 43, the signal acquisition component 4 and the aluminum bars 5 are connected, and the stability of the overall structure is improved.

[0051] As Figure 5 and Figure 8As shown, in some embodiments of the present invention, the nickel sheet 43 includes a first horizontal member 431, a vertical member 432, and a second horizontal member 433. The two ends of the vertical member 432 are connected to the first horizontal member 431 and the second horizontal member 433, respectively. It should be noted that the first horizontal member 431, the vertical member 432, and the second horizontal member 433 can be either an integrated structure or a separate structure. The first horizontal member 431 is connected to the circuit board 41, and the second horizontal member 433 is connected to the aluminum bar 5. The vertical member 432 is arranged at a certain height, thereby elevating the circuit board 41 relative to the base plate 1, so that the signal acquisition component 4 is arranged as a whole directly above the base plate 1. This design concept solves the problem of an overly wide aluminum bar that leaves no space for the signal acquisition component 4 when designing a high-current module. At the same time, the welding position of the nickel sheet 43 and the welding position of the aluminum bar 5 are in the same position, thereby achieving overlap welding, that is, the second horizontal member 433 and the aluminum bar 5 are welded together in one go, effectively reducing production costs and improving module assembly efficiency. Exemplarily, the nickel sheet 43 formed by the first horizontal piece 431 , the vertical piece 432 and the second horizontal piece 433 is in a “Z” shape.

[0052] like Figures 1-11 As shown, the present invention also provides a battery module comprising: the integrated busbar 10 and a cell assembly 20 as described above. The integrated busbar 10 is disposed on the cell assembly 20. The integrated busbar 10 connects the various components into a single unit through processes such as thermal compression or riveting, enabling high-voltage series and parallel connection of the cells in the cell assembly 20, as well as battery temperature and cell voltage sampling functions.

[0053] The battery cell assembly 20 is composed of, for example, soft-pack battery cells. Since a large number of soft-pack battery cells can be stacked, the more signal points that need to be collected, the more pins of the connector 3 will be correspondingly large. When the number of pins is too large, the connector 3 needs to use a greater force to plug and unplug the connector, but using a greater force will damage the copper wire in the circuit board 41. Therefore, the utility model provides a connector at both ends of the circuit board 41, that is, a double-headed inverted connector is used, which can evenly divide the number of collection points of the signal collection assembly 4 to meet the signal point collection requirements, and effectively reduce the number of pins of the connector 3, making the connector 3 easy to plug and unplug, and avoiding the risk of damaging the copper wire due to excessive plugging and unplugging force.

[0054] At the same time, the signal acquisition component 4 of the integrated busbar 10 is placed directly above the base plate 1, and the aluminum bar 5 is placed at the lower end of the signal acquisition component 4. At this time, the nickel sheet 43 and the aluminum bar 5 can be stacked and welded. Compared with the high cost of first integrating the CCS assembly and then welding the CCS assembly to the battery cell assembly 20 in the prior art, the stacking welding realized by the present invention can directly weld the nickel sheet 43, aluminum bar 5, copper busbar and tab together at one time, which greatly reduces the cost and improves the efficiency of module assembly.

[0055] like Figure 10-11 As shown, in some embodiments of the present invention, the battery module further includes end plates 30. Two end plates 30 are disposed on either side of the battery cell assembly 20, and the support plate 2 abuts against the end plates 30. When the integrated busbar 10 is placed on the battery cell assembly 20, the first bent member 24 and the second bent member 25 of the support plate 2 abut against the upper ends of the end plates 30. Because the support plate 2 is inherently rigid, it effectively increases the strength of the base plate 1 at the mounting location of the connector 3. Furthermore, because the first bent member 24 and the second bent member 25 abut against the upper ends of the end plates 30, the support function is enhanced.

[0056] like Figure 11 As shown, some embodiments of the present invention also include a battery management system. The battery management system is disposed on the side wall of the end plate 30 and is electrically connected to the corresponding connector 3. The temperature and voltage signals collected by the signal acquisition component 4 are transmitted to the battery management system via the connector 3.

[0057] It should be understood that the Battery Management System (BMS) is a device that monitors the status of energy storage batteries. Its main function is to intelligently manage and maintain each battery unit, prevent overcharging and over-discharging of the battery, extend the battery life, and monitor the battery status.

[0058] It should be noted that the above and below described in this article are Figures 1-6 Shown above and below.

[0059] In summary, the utility model provides an integrated busbar and battery module, which forms an accommodating cavity by designing the incision of the base plate and the support plate. When the connector is placed in the accommodating cavity, it is placed below the support plate, that is, an inverted connector is designed, which can save the height space of the battery module and the installation space of the connecting copper busbar; and a connector is connected to each end of the circuit board, that is, two connectors are designed. When the number of battery cells is too large, the number of pins of the connector can be effectively reduced, which is convenient for plugging and unplugging the connector connectors, and can also meet the needs of multi-signal point acquisition; at the same time, by designing the support plate structure of the horizontal plate, the first bent member and the second bent member, not only the strength of the base plate is enhanced, but also supporting force is provided when abutting the end plate; and, by designing the nickel sheet structure of the first horizontal member, the vertical member and the second horizontal member, the height of the signal acquisition component relative to the base plate is raised, that is, it is placed above the aluminum bar, thereby increasing the width design space of the signal acquisition component; at the same time, the welding position of the nickel sheet is at the same position as the welding position of the aluminum bar, and can be directly overlapped, reducing the welding steps, reducing costs, and effectively improving the module assembly efficiency. Therefore, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0060] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
