Abstract
Description
Technical Field
[0001] The present application relates to the field of battery technology, and in particular to a battery board, a battery cell module and a battery. Background Art
[0002] In the battery field, when the copper busbar of the battery cell is directly welded to the slave board, the pins on both sides of the slave board are often divided into odd and even. For battery cells with odd and even terminals on both sides, the pins on both ends of the slave board can be connected to the corresponding battery cell terminals through wires. However, some battery cells may have a copper busbar jumper in the middle, that is, the terminals on both sides of the battery cell are not completely separated by odd and even. There may be an even terminal on the side of the odd terminal, and an odd terminal on the side of the even terminal. In this case, voltage still needs to be collected at both ends of the copper busbar, which disrupts the parity on both sides, resulting in a mismatch between the copper busbar terminals and the slave board pins on both sides, and the need to fly out a long wire for jumper connection, resulting in crossed flying wires, and the slave board cannot be used for all battery cells, resulting in increased costs. Utility Model Content

[0006] Furthermore, along the extension direction of the first side, the pins on the first side are numbered in descending order, and along the extension direction of the second side, the pins on the second side are numbered in descending order, and the size of the additional number is between the number size range of the two pins adjacent to the additional pin.
[0007] Furthermore, the pins are numbered sequentially starting from 1, and additional numbers include 8 and 17.
[0008] Furthermore, one of the two pins adjacent to the additional pin and the pin with the same number as the additional pin are arranged opposite to each other along a connection direction between the first side and the second side.

[0010] Furthermore, at least one of the pin with the same number as the additional number and the additional pin is electrically connected to the battery cell through a wire.
[0011] Furthermore, there are multiple slave plate bodies, and the slave plate bodies are connected in sequence along the extension direction of the first side.
[0012] Further, the first sides of all the slave board bodies are connected in sequence, so that the first sides of all the slave board bodies are located on the same side of the battery slave board.
[0013] Furthermore, for the same slave board body, the pins are numbered sequentially starting from 1, there are at least three slave board bodies, and among the three adjacent slave board bodies, the additional number of the middle slave board body is 8, and the additional number of the slave board bodies at both ends is 17.

[0015] Instruction manual PN279487HZYWLN
[0016] According to another aspect of the present application, a battery cell module is provided, comprising a battery cell and the above-mentioned battery slave board, wherein the battery cell has connection terminals on opposite sides, and the connection terminals are electrically connected to the pins of the battery slave board through wires.
[0017] According to another aspect of the present application, a battery is provided, comprising the above-mentioned battery cell module.
[0018] By applying the technical solution of the present application, an additional pin is provided, and the additional number of the additional pin is the same as the number of the pin, so that the additional pin can play the same role as the pin, and since the side where the additional pin is located is opposite to the side where the pin is located, that is, when the pin is located on the first side, the additional pin is located on the second side, and when the pin is located on the second side, the additional pin is located on the first side, in this way, the pin and the additional pin are respectively located on both sides of the board body, so that when the battery cell is connected to the copper busbar, the unconventional terminal can directly cross over part of the terminal and be connected to the pin with a larger number. Since the crossed pin cannot be left vacant, the crossed pin can be connected to the additional pin on its side through a wire, so that the crossed pin will not be left vacant, thereby ensuring accurate voltage acquisition.

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application 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 meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.
[0029] In this application, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; 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 directional words are not used to limit this application.
[0030] It should be noted that when connecting the voltage collection from the board body 10, the size of the pin 20 number is positively correlated with the voltage requirement it needs to meet. It is necessary to ensure that the voltage values collected are in order from small to large or remain unchanged. That is to say, among the two adjacent numbered pins 20, the voltage value collected by the larger pin 20 cannot be lower than the voltage value collected by the smaller pin 20, so as to ensure normal use.
[0031] In order to solve the problem of difficulty in wiring between the slave board and the battery cell 40 in the prior art, the present application provides a battery slave board, a battery cell module and a battery.
[0032] like Figures 1 to 4 A battery slave board shown includes a slave board body 10, the slave board body 10 has a plurality of pins 20, each pin 20 has a number, the slave board body 10 has a first side and a second side opposite to each other, the pins 20 with odd numbers are located on the first side, and the pins 20 with even numbers are located on the second side, the slave board body 10 also has additional pins 30, the additional pins 30 have additional numbers, and the additional number is the same as the number of one pin 20, and when the additional number is odd, it is located on the second side, and when the additional number is even, it is located on the first side.
[0033] In this embodiment, an additional pin 30 is provided, and the additional number of the additional pin 30 is the same as the number of the pin 20, so that the additional pin 30 can play the same role as the pin 20, and since the side where the additional pin 30 is located is opposite to the side where the pin 20 is located, that is, when the pin 20 is located on the first side, the additional pin 30 is located on the second side, and when the pin 20 is located on the second side, the additional pin 30 is located on the first side. In this way, the pin 20 and the additional pin 30 are respectively located on both sides of the board body 10, so that when the battery cell 40 is bridged by the copper bus, the unconventional terminal can directly bridge over part of the terminal and connect to the pin 20 with a larger number. Since the bridged pin 20 cannot be left vacant, the bridged pin 20 can be connected to the additional pin 30 on its side through a wire, so that the bridged pin 20 will not be left vacant, thereby ensuring accurate voltage collection. Due to the setting of the additional terminal, the above-mentioned setting method allows the unconventional terminals on the battery cell 40 to be adjusted to the connection terminals as needed. The connection terminals that are crossed by the unconventional terminals can be connected together with the additional terminals, thereby avoiding the situation where the pin 20 is vacant. In this way, the accuracy and reliability of voltage collection are guaranteed, and the use of flying wire jumper connection is avoided, thereby achieving convenience in wiring and helping to reduce costs.
[0034] Instruction manual PN279487HZYWLN
[0035] It should be noted that the numbers and additional numbers mentioned in this embodiment are not simply set arbitrarily. The numbers in the numbers and additional numbers actually represent the voltage relationship that needs to be collected between the pins 20. Therefore, each pin 20 has a unique number to represent the voltage size it needs.
[0036] like Figure 1As shown, in this embodiment, along the extension direction of the first side, the pins 20 on the first side are numbered sequentially from large to small, and along the extension direction of the second side, the pins 20 on the second side are numbered sequentially from large to small. In this way, the arrangement of the pins 20 is the same as the arrangement of the terminal of the battery cell 40, which facilitates sequential wiring and achieves the arrangement of the wires. For the additional pins 30, this embodiment adopts an additional number size that is between the number size range of the two pins 20 adjacent to the additional pin 30. That is to say, the additional pin 30 is not set in a separate position independent of the pin 20, but is integrated between the pins 20. The additional pin 30 is also arranged in sequence according to the size relationship between the additional number and the number of the side. For example, when there is no additional pin 30, the pins 20 are numbered 1, 3, 5, and 7 in sequence, and the additional number of the additional pin 30 is 6. When there is an additional pin 30, the overall number of the side is 1, 3, 5, 6, and 7. In this way, the position of the additional pin 30 can be adjacent to the terminal crossed by the unconventional terminal in the battery cell 40, so that the wiring can be connected in sequence, which is more convenient and the wires after wiring are avoided as much as possible.
[0037] Preferably, the pins 20 are numbered sequentially starting from 1, with additional pins 30 including 8 and 17. Considering the varying number of battery cells 40 in a string, this embodiment preferably includes additional pins 30 for the pins 20 numbered 8 and 17, thereby increasing the versatility of the battery module. Of course, other additional pins 30 may be added as needed.
[0038] In this embodiment, one of the two pins 20 adjacent to the additional pin 30 and the pin 20 with the same number as the additional pin are positioned opposite each other along the line connecting the first side and the second side. In other words, the additional pin 30 (PN279487HZYWLN) and the pin 20 with the same number and magnitude are positioned substantially opposite each other on opposite sides of the slave board body 10, thereby ensuring that the two are positioned substantially in the same direction, thereby facilitating wiring convenience.
[0039] Optionally, the pin 20 with the same number as the additional number is electrically connected to the additional pin 30 via a conductor. That is, the additional pin 30 and the corresponding pin 20 can be completely independent of each other, or they can be electrically connected. In this case, only one of the additional pin 30 and the corresponding pin 20 can be connected to the outside via a conductor, while the other can be left unconnected. The specific configuration can be customized based on actual needs.
[0040] At the same time, this embodiment also adopts a configuration method in which at least one of the pins 20 and the additional pins 30 with the same number as the additional number is electrically connected to the battery cell 40 via a conductor, while the other can be connected to an adjacent pin 20. The adjacent pin 20 is the pin 20 that the aforementioned unconventional terminal crosses. For some pins 20 or additional pins 30 that do not need to be connected to the terminal of the battery cell 40, they can be electrically connected to the adjacent pins 20 via a small piece of wire, thereby forming an electrical connection between the additional pin 30 and at least one adjacent pin 20 via a conductor; or the pin 20 with the same number as the additional number is electrically connected to at least one adjacent pin 20 via a conductor. Of course, if the additional pin 30 and the corresponding pin 20 are already electrically connected, one of the two can be left vacant.
[0041] Optionally, the number of slave board bodies 10 can be set as needed, and can be one or more. This embodiment adopts a method of providing multiple slave board bodies 10, and each slave board body 10 is connected sequentially along the extension direction of the first side. In this way, the pins 20 on each slave board body 10 can respectively mate with the corresponding terminal on the battery cell 40, thereby achieving corresponding matching between the battery slave board and the battery cell 40. The slave board bodies 10 can be connected by post-assembly or by an integrated arrangement, so that the battery slave board forms a whole.
[0042] Instruction manual PN279487HZYWLN
[0043] Taking into account practical wiring requirements, this embodiment sequentially connects the first sides of all slave board bodies 10 so that the first sides of all slave board bodies 10 are located on the same side of the battery slave board. That is, regardless of which slave board body 10 is used, for the entire battery slave board, one side of the slave board has odd-numbered pins 20, and the other side has even-numbered pins 20. Only the additional pins 30 are arranged in the opposite manner: the even-numbered additional pins 30 are located on the side of the odd-numbered pins 20, and the odd-numbered additional pins 30 are located on the side of the even-numbered pins 20.
[0044] Preferably, for the same slave board body 10, the pins 20 are numbered in sequence starting from 1, there are at least three slave board bodies 10, and among the three adjacent slave board bodies 10, the additional number of the middle slave board body 10 is 8, and the additional numbers of the slave board bodies 10 at both ends are both 17. Each slave board body 10 of this embodiment is provided with 18 pins 20 and one additional pin 30. Therefore, based on the above-mentioned setting method, the three slave board bodies 10 are, that is, the first side of the slave board body 10 at both ends is the pins 20 numbered 1, 3, 5, 7, 9, 11, 13, 15, 17, and the second side is the pins 20 and additional pins 30 numbered and additionally numbered 2, 4, 6, 8, 10, 12, 14, 16, 17, and 18; and the first side of the slave board body 10 in the middle of the two ends is the pins 20 and additional pins 30 numbered and additionally numbered 1, 3, 5, 7, 8, 9, 11, 13, 15, 17, and the second side is the pins 20 numbered 2, 4, 6, 8, 10, 12, 14, 16, and 18. Among them, a pin 20 numbered 0 may be additionally provided on the slave board body 10 at one end. Pin 20 numbered 0 is provided on the second side of the even-numbered section and is located before pin 20 numbered 2, thereby forming pins 20 numbered 0, 2, 4, 6, 8, 10, 12, 14, 16, 17, and 18. Through the above arrangement, the convenience and organization of wiring between the battery slave board and the battery cells 40 are improved, and the formed battery slave board has extremely high versatility and is compatible with battery cells 40 of various numbers such as 48S, 50S, and 52S.
[0045] This embodiment also provides a battery cell module, including a battery cell 40 and the above-mentioned battery slave board. The battery cell 40 has terminals on opposite sides, and the terminals are electrically connected to the pins 20 of the battery slave board through wires. Among them, most of the terminals are arranged in a manner that odd numbers are on one side and even numbers are on the other side. However, there are some additional terminals. Although the additional terminals are odd-numbered, they are arranged on the even-numbered side, thus forming a cross-copper busbar. When connecting, the additional terminals need to adjust the connected pins 20 to ensure the voltage relationship between the pins 20. Since the additional pins 30 of this embodiment are arranged on the side opposite to the odd and even numbers, after the additional terminals adjust the connected pins 20, the additional pins 30 can be easily connected to the cross-over pins 20 without flying wires or crossing.
[0046] This embodiment also provides a battery, including the above-mentioned battery cell module.
[0047] To facilitate explanation of the specific wiring method between the battery slave board and the battery cell 40, this embodiment shows the connection between the battery slave board and three types of battery cells 40 with different numbers of 48S, 50S, and 52S. The additional pin 30 with the additional number 8 plays a major role. The upper side in the figure is the first side, and the lower side is the second side. When wiring, it is necessary to meet the requirements of the numbering of pins 20. The voltage values need to increase or remain unchanged in sequence and cannot decrease. The specific wiring is as follows:
[0048] like Figure 2 As shown, for the battery cell 40 with a string number of 48S, the upper side is the odd-numbered terminals and the lower side is the even-numbered terminals, but there is a B25- terminal in the even-numbered terminals on the lower side. The B25- terminal is located between the B24 and B26 terminals, so B25 and B25- are additional terminals. Based on the above situation, since this embodiment adds an additional pin 30 with the number 8 on the upper side of the middle slave board body 10, the additional terminal B25- on the lower side is connected to the pin 20 with the number 10, while the terminal B25 on the upper side can cross the pin 20 with the number 9 and connect to the pin 20 with the number 11. The crossed pin 20 with the number 9 is connected to the additional pin 30 with the number 8 through a wire. In this way, the voltage of the pin 20 with the number 11 is higher than the voltage of the pin 20 with the number 10, meeting the wiring requirements. Since the pin 20 with the number 9 is connected to the additional pin 30 with the number 8, the situation where the pin 20 with the number 9 has no connection object and is left vacant can be avoided. In this way, it is ensured that the wiring meets the requirements and the occurrence of flying wires and crossing is avoided.
[0049] Instruction manual PN279487HZYWLN
[0050] With respect to the additional terminals numbered 17 attached to the slave board body 10 at both ends, in this embodiment, the pin 20 numbered 17 on the upper side of the leftmost slave board body 10 is left vacant, while the additional pins 30 and 20 numbered 17 and 18 on the lower side are connected to the pin 20 numbered 16 via wires. Simultaneously, the pin 20 numbered 17 on the upper side of the rightmost slave board body 10 is connected to the pin 20 numbered 15 via wires, while the additional pins 30 and 20 numbered 17 and 18 on the lower side are connected to the pin 20 numbered 16 via wires.
[0051] like Figure 3As shown, for the battery cell 40 with a string number of 50S, the upper side is the odd-numbered terminals and the lower side is the even-numbered terminals, but there is a B26- terminal among the odd-numbered terminals on the upper side. The B26- terminal is located between the terminals B25 and B27, so B26 and B26- are additional terminals. Based on the above situation, since this embodiment still utilizes the additional pin 30 with the additional number 8 on the middle slave board body 10, the additional terminal B26- on the upper side is connected to the pin 20 with the number 9, and the terminal B26 on the lower side can cross the pin 20 with the number 8 and be connected to the pin 20 with the number 10, and the crossed number 8 can be connected to the additional pin 30 with the additional number 8 through a wire between the pin 20 with the number 7, thereby satisfying the voltage values of the pins 20 with the number 7, the pin 20 with the number 8, the pin 20 with the number 9, and the pin 20 with the number 10 to increase or remain unchanged in sequence, while avoiding the situation where the pin 20 with the number 8 is vacant, and also avoiding the occurrence of flying wires and crossings.
[0052] As for the additional terminals numbered 17 and the pins 20 numbered 16 and 18 adjacent to the slave board body 10 at both ends, their specific connection methods can also be adjusted as needed, which will not be described in detail here.
[0053] like Figure 4 As shown, for a battery cell 40 with a string number of 52S, the upper side has odd-numbered terminals and the lower side has even-numbered terminals. However, among the lower odd-numbered terminals, there is a terminal B27- located between the terminals B26 and B28. Therefore, B27 specification PN279487HZYWLN and B27- are additional terminals. Based on the above situation, since this embodiment still utilizes the additional pin 30 numbered 8 on the middle slave board body 10, the additional terminal B27 on the upper side crosses the pin 20 numbered 9 and connects to the pin 20 numbered 11, while the terminal B27- on the lower side can be connected to the pin 20 numbered 10, and the terminal numbered 9 on the upper side can be connected to the additional pin 30 numbered 8 via a wire. In this way, the voltage of pin 20 numbered 11 is higher than the voltage of pin 20 numbered 10, which meets the wiring requirements. Pin 20 numbered 9 is connected to the additional pin 30 numbered 8, which can avoid the situation where pin 20 numbered 9 is not connected to an object and is left vacant. This ensures that the wiring meets the requirements and avoids the occurrence of flying wires and crossing.
[0054] The above three specific embodiments only illustrate the definition of the connection of 48S-52S. This range is mainly used for the 800V platform of the L300 battery cell. If it is the 800V platform of the L200 battery cell, there may be only two slave board bodies 10. At this time, two additional pins 30 with additional number 17 on the slave board body 10 can be used to achieve wiring.
[0055] It should be noted that, in the above embodiments, a plurality refers to at least two.
[0056] From the above description, it can be seen that the above embodiments of the present application achieve the following technical effects:
[0057] 1. Solve the problem of difficult wiring between the slave board and the battery cell in the prior art;
[0058] 2. Avoid pin vacancy to ensure accurate voltage acquisition;
[0059] 3. It avoids the use of flying wire jumper connection, thereby achieving the convenience of wiring and helping to reduce costs.
