Referring to fig. 1 to 3 together, the present application discloses a conductive connection member 1 and a battery module 10, the conductive connection member 1 is applied to the battery module 10, specifically, the battery module 10 includes a plurality of battery cells 2 and an output structure 3, the conductive connection member 1 includes a first conductive connection portion 11 and a second conductive connection portion 12, the first conductive connection portion 11 has a first connection portion 111 and a second connection portion 112 connected to the first connection portion 111, the first connection portion 111 and the second connection portion 112 are connected and are respectively used for connecting with the end portions of two adjacent battery cells 2, the second conductive connection portion 12 is connected to the first connection portion 111 and/or the second connection portion 112, the extending direction y of the second conductive connection portion 12 is different from the first direction x, the second conductive connection portion 12 is used for connecting to the output structure 3, the second conductive connection portion 12 has a fusing portion 121, the first direction x is an arrangement direction of the first connection portion 111 and the second connection portion 112.
The conductive connection member 1 disclosed in the first aspect of the present application includes a first conductive connection portion 11 and a second conductive connection portion 12, a first connection portion 111 and a second connection portion 112 of the first conductive connection portion 11 are respectively used for connecting to two adjacent battery cells 2, and the second conductive connection portion 12 is connected to the output structure 3, so that, when energized, the current of the battery cells 2 is output from the output structure 3 through the first conductive connection portion 11 and the second conductive connection portion 12. Because the extending direction y and the first direction x of second electrically conductive connecting portion 12 are different, then, when this electrically conductive connecting piece 1 is applied to battery module 10, first electrically conductive connecting portion 11 is connected in the tip of electricity core 2, second electrically conductive connecting portion 12 is then not corresponding to the tip of electricity core 2, consequently, the fusing part 121 of second electrically conductive connecting portion 12 is also not corresponding to the tip of electricity core 2, thereby can avoid the condition that the fusing liquid that produces when fusing part 121 fuses drips to the tip of electricity core 2 and damages electricity core 2, be favorable to improving battery module 10's security. It can be understood that the battery module 10 having the conductive connection member 1 has high safety.
It should be noted that the conductive connecting member 1 is a conductive member, and the connection between the conductive connecting member and the battery cell 2 and the output structure 3 includes not only structural connection but also electrical connection, so as to achieve a conductive function.
It should be noted that the extending direction y of the second conductive connection portion 12 may be understood as a direction from one end of the connection of the second conductive connection portion with the first connection portion 111 and/or the second connection portion 112 to the other end opposite thereto. When the second conductive connection portion 12 is in an elongated structure, the extending direction y of the second conductive connection portion 12 is the length direction of the second conductive connection portion 12.
The first direction x is an arrangement direction of the first connection portions 111 and the second connection portions 112, and it is understood that the first connection portions 111 face the second connection portions 112, or the second connection portions 112 face the first connection portions 111.

It can be understood that the battery cell 2 has a generally square structure, and in order to reasonably utilize the gap between the battery cell 2 and the housing 4 of the battery module 10 to arrange the conductive connecting member 1, in some embodiments, an included angle between the extending direction y of the second conductive connecting portion 12 and the first direction x is 90 ° to 180 °, and optionally, an included angle between the extending direction y of the second conductive connecting portion 12 and the first direction x is 90 °, 120 °, 150 °, 180 °, and the like. Like this, can arrange electrically conductive connecting piece 1 in the clearance between electric core 2 and the casing 4 of battery module 10 of rational utilization, be favorable to improving battery module 10's integrated level. Exemplarily, the included angle between the extending direction y of the second conductive connecting portion 12 and the first direction x is 90 °, and when the first connecting portion 111 and the second connecting portion 112 are connected to the end portions of two adjacent battery cores 2, the second conductive connecting portion 12 is located at the side portion of the battery core 2 and is parallel to the side wall surface of the battery core 2, so that the second conductive connecting portion 12 has a simple structure and reasonably utilizes the space between the battery core 2 and the housing 4 of the battery module 10, which is beneficial for realizing the miniaturization design of the battery module 10.
Alternatively, the first conductive connecting portion 11 and the second conductive connecting portion 12 of the conductive connecting member 1 may be integrally formed, so as to simplify the processing process of the conductive connecting member 1, improve the structural strength of the conductive connecting member 1, and improve the conductive performance of the conductive connecting member 1.
Alternatively, the conductive connection member 1 may have a sheet structure, the first conductive connection portion 11 may have an elongated sheet structure, and the second conductive connection portion 12 also has an elongated sheet structure, and the length direction of the first conductive connection portion 11 is perpendicular to the length direction of the second conductive connection portion 12. In order to realize better conductivity of the conductive connecting member 1, the first conductive connecting portion 11 may be a metal sheet, such as an aluminum sheet, a copper sheet, or the like.
Specifically, the thickness of the conductive connecting member 1 may be 0.8mm to 1.2mm, for example, the thickness of the conductive connecting member 1 is 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, and the like, and by reasonably setting the thickness of the conductive connecting member 1, the conductive connecting member 1 can be ensured to be light and thin and have a better current-carrying capacity. When the thickness of the conductive connecting member 1 is greater than 1.2mm, the thickness of the conductive connecting member 1 is too thick, and the overall size of the battery module 10 is increased when the battery module 10 is assembled, which is not favorable for the miniaturization design of the battery module 10. When the thickness of the conductive connection member 1 is less than 0.8mm, the thickness of the conductive connection member 1 is small, resulting in a small structural strength and a weak current-carrying capacity.
In some embodiments, the first connection portion 111 and the second connection portion 112 are each provided with a connection hole 11a to be connected to two adjacent battery cells 2 through the connection hole 11a, and the aperture of the connection hole 11a is 1mm to 2 mm. All set up connecting hole 11a through first connecting portion and second connecting portion 112 to can supply laser through-hole 12a, in order to realize location and welding, be 1mm ~ 2mm through the aperture that sets up connecting hole 11a, can supply the laser of sufficient volume to pass through in order to realize the positioning action of preferred and improve welding strength.
In some embodiments, the cross-sectional area of the fusing part 121 is smaller than the cross-sectional area of the second conductive connecting part 12 in a direction perpendicular to the thickness direction of the conductive connecting part 1. Since the cross-sectional area of the fusing part 121 is small, the resistance of the fusing part 121 is large, so that more heat is generated when current flows through the fusing part 121, the fusing part 121 is more easily fused, and an overload protection function can be performed.
In an alternative embodiment, the width of the fusing part 121 is smaller than that of the second conductive connection part 12, thereby realizing a smaller sectional area of the fusing part 121 to perform an overload protection function.
In another alternative embodiment, as shown in fig. 3, the fusing part 121 is provided with a plurality of through holes 12a, and the plurality of through holes 12a are spaced apart in the width direction of the second conductive connecting part 12 such that the cross-sectional area of the fusing part 121 is smaller than that of the second conductive connecting part to perform an overload protection function.
Alternatively, the interval between two adjacent through holes 12a is 0.8mm to 1.5mm, and illustratively, the interval between two adjacent through holes 12a may be 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.5mm, or the like. By reasonably setting the distance between two adjacent through holes 12a, the fusing part 121 can be ensured to have sufficient structural strength and can effectively realize the overload protection function. When the interval between the adjacent two through holes 12a is greater than 1.5mm, the sectional area of the fusing part 121 is large, so that it is difficult to achieve a preferable overload protection effect, and if the interval between the adjacent two through holes 12a is less than 0.8mm, the structural strength of the fusing part 121 may be weak.
It should be noted that the pitch between two adjacent through holes 12a refers to the minimum pitch between the hole walls of two adjacent through holes 12 a.
Alternatively, the through hole 12a may be a circular hole, a square hole, a kidney-shaped hole, or the like, and the shape of the through hole 12a may be any shape, which is not particularly limited in this embodiment.
It can be understood that the first connection portion 111 and the second connection portion 112 of the first conductive connection portion 11 need to be connected to two adjacent battery cells 2, if the first connection portion 111 and the second connection portion 112 are not in the same plane due to processing errors, the connection difficulty between the first connection portion 111 and the second connection portion 112 and the two adjacent battery cells 2 is large, if the end portions of the two adjacent battery cells 2 are not in the same plane due to assembly errors of the battery cells 2, the connection difficulty between the first connection portion 111 and the second connection portion 112 and the two adjacent battery cells 2 is also large, therefore, the flatness of the first connection portion 111 and the second connection portion 112 needs to be adjusted during assembly, and similarly, one end of the second conductive connection portion 12 is connected to the first conductive connection portion 11, and the other end of the second conductive connection portion 12 is connected to the output structure 3, then, the flatness of both ends of the second conductive connecting portion 12 also needs to be adjusted at the time of assembly.
In view of this, in some embodiments, the first conductive connection portion 11 further has a first bent portion 113, the first bent portion 113 is connected between the first connection portion 111 and the second connection portion 112, and/or the second conductive connection portion 12 is provided with a second bent portion 122, and the second bent portion 122 is connected to the fusing portion 121. In other words, the first conductive connection portion 11 is provided with the first bending portion 113, and the second conductive connection portion 12 is provided with the second bending portion 122, or the first conductive connection portion 11 is provided with the first bending portion 113 and the second conductive connection portion 12 is provided with the second bending portion 122. By arranging the first bending part 113 between the first connecting part 111 and the second connecting part 112 of the first conductive connecting part 11, when the flatness of the first connecting part 111 and the second connecting part 112 needs to be adjusted to be adapted to the battery cell 2, the relative positions of the first connecting part 111 and the second connecting part 112 can be adjusted by bending the first bending part 113, and when the flatness of the two ends of the second conductive connecting part 12 needs to be adjusted, the flatness of the two ends of the second conductive connecting part 12 can be adjusted by bending the second bending part 122, so that the assembly is facilitated.
Optionally, when the second conductive connection portion 12 is provided with the second bending portion 122, the second conductive connection portion 12 further has a third connection portion 123, the second bending portion 122 is connected between the fusing portion 121 and the third connection portion 123, the third connection portion 123 is used for being connected to the output structure 3, and the fusing portion 121 is connected to the first connection portion 111 and/or the second connection portion 112. Like this, when this electrically conductive connecting piece 1 assembles in battery module 10, fusing part 121 is located the one side that second bending part 122 is close to the top of electric core 2, then, when fusing part 121 fuses, fusing liquid that fusing part 121 fusing produced can be accepted to second bending part 122, avoids fusing liquid to drip to other parts and leads to damaging the condition of other parts.
It can be understood that, when the conductive connecting member 1 is assembled to the battery module 10, the second conductive connecting portion 12 is closer to the inner wall surface of the housing 4 of the battery module 10, so as to avoid the contact between the second conductive connecting portion 12 and the inner wall surface of the housing 4, which may cause the housing 4 to be electrically connected, in some embodiments, the second conductive connecting portion 12 is sleeved with the insulating sleeve 13, when the second conductive connecting portion 12 is provided with the second bending portion 122, at least a portion of the insulating sleeve 13 is sleeved on the second bending portion 122, and the second bending portion 122 is an arc-shaped structure. Set up insulating cover 13 through second conductive connection portion 12 and can avoid second conductive connection portion 12 and box contact and lead to the condition that the box connects the electricity, and insulating cover 13 is at least partly the cover and locates second bending part 122, second bending part 122 has played the positioning action to insulating cover 13, make insulating cover 13 be fixed in second conductive connection portion 12 more firmly, and simultaneously, be the arc bending structure through setting up second bending part 122, thus, the arc bending structure does not have the edges and corners thereby it laminates with insulating cover 13 to change in, with the insulating nature of the reliability that improves insulating cover 13 and second conductive connection portion 12.
Specifically, the insulating sleeve 13 may be a heat-shrinkable sleeve, which is sleeved on the second conductive connecting portion 12 and then tightly sleeved on the second conductive connecting portion 12 by heating.
Further, the radius of curvature of the second bent portion 122 is 3.5mm to 5mm, and exemplarily, the radius of curvature of the second bent portion 122 is 3.5mm, 3.8mm, 4mm, 4.3mm, 5mm, and the like. The curvature radius of the second bending part 122 is 3.5 mm-5 mm, the second bending part 122 has a better curvature radius range, and the bending radian of the second bending part 122 is gentler, so that the second bending part can be better attached to the insulating sleeve 13.
As can be seen from the foregoing, the second conductive connecting portion 12 is electrically connected to the output structure 3, and in order to better fix the position of the second conductive connecting portion 12, in an optional embodiment, the battery module 10 further includes a cell baffle (not shown in the figure), the cell baffle is parallel to the side portion of the cell 2, and the second conductive connecting portion 12 is fixed to the cell baffle. Since the extending direction y of the second conductive connecting portion 12 is perpendicular to the second conductive connecting portion 12 of the first direction x, that is, the second conductive connecting portion 12 is parallel to the side surface of the battery cell 2, by connecting the second conductive connecting portion 12 to the baffle of the battery cell 2 parallel to the side portion of the battery cell 2, the mounting manner is simple and the reliability is high.
Considering that the second conductive connecting portion 12 is fixed to the cell baffle, when detaching the cell 2 baffle of the battery module 10, the second conductive connecting portion 12 needs to be detached from the cell baffle first, and the detachment of the cell baffle is cumbersome, based on this, in another optional embodiment, the end of the second conductive connecting portion 12 away from the first conductive connecting portion 11 is provided with the mounting portion 14, and the mounting portion 14 is used for connecting to the casing 4 of the battery module 10 and insulating from the casing 4. Like this, can improve the steadiness of the installation of second electrically conductive connecting portion 12, can also avoid influencing demolising of electric core 2 baffle.
Alternatively, the extension of the mounting portion 14 from the second conductive connecting portion 12 in a direction away from the second conductive connecting portion 12, in other words, when the conductive connecting member 1 is assembled to the battery module 10, the mounting portion 14 is substantially parallel to the bottom surface of the housing 4 of the battery module 10, thereby facilitating the mounting to the bottom surface of the housing 4.
Specifically, the bottom surface of the housing 4 may be provided with the bearing portion 41, and the mounting portion 14 is provided with the mounting hole 141, so that it can be mounted to the bearing portion 41 by passing a screw through the mounting hole 141.
More specifically, in order to achieve insulation between the mounting portion 14 and the housing 4, the bearing portion 41 may adopt an insulation structure, and exemplarily, the bearing portion 41 is an insulation column. It will be appreciated that in other embodiments, the mounting portion 14 may be insulated from the carrier portion 41 by providing an insulator between the mounting portion 14 and the carrier portion 41.
It is understood that the battery module 10 is provided with a voltage monitoring module for monitoring the voltage of each battery cell 2, and the voltage monitoring module needs to be electrically connected to the conductive connecting member 1 through a connecting wire to monitor the voltage of the battery cell 2, based on which, in some embodiments, the conductive connecting member 1 further includes a connecting portion 15, the connecting portion 15 is connected to the first connecting portion 111 and/or the second connecting portion 112, and a gap 16 is formed between at least part of the connecting portion 15 and the first connecting portion 111 or the second connecting portion 112. Since at least a part of the electric connecting part 15 has a gap 16 with the first connecting part 111 or the second connecting part 112, it is possible to provide a sufficient connecting space for the electric connecting wire.
It should be noted that the connection of the electrical connection part 15 to the first connection part 111 and/or the second connection part 112 includes the connection of the electrical connection part 15 to the first connection part 111, or the connection of the electrical connection part 15 to the second connection part 112, or the connection of the electrical connection part 15 to the first connection part 111 and the second connection part 112.
Further, the electric connection part 15 is connected to the first connection part 111, and the extending direction y of the electric connection part 15 is parallel to the first direction x, in other words, the electric connection part 15 extends from the first connection part 111 toward the second connection part 112, so that the electric connection part 15 has a sufficient extending length, and therefore, the length of the electric connection part 15 can be set long enough to be stably connected to the electric connection wire, and in addition, a space of the battery cell 2 in the direction perpendicular to the first direction x is not occupied compared with the case that the electric connection part 15 extends in the direction perpendicular to the first direction x, so that other components, for example, a bead pressed against the battery cell 2, can be arranged.
The electrically conductive connecting piece 1 of the first aspect of this application, extending direction y through setting up the electrically conductive connecting part 12 of second even is different with first direction x, then, when this electrically conductive connecting piece 1 is applied to battery module 10, first electrically conductive connecting part 11 does not correspond to the tip of electric core 2, therefore, the fusing part 121 of the electrically conductive connecting part 12 of second also does not correspond to the tip of electric core 2, thereby can avoid the condition that the fusing liquid that produces when fusing part 121 fuses drips to the tip of electric core 2 and damages electric core 2, be favorable to improving battery module 10's security.
The conductive connecting piece and the battery module disclosed in the embodiment of the present invention are described in detail above, and the principle and the implementation of the present invention are explained herein by applying specific examples, and the description of the above embodiments is only used to help understanding the conductive connecting piece and the battery module and the core idea thereof; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, and in summary, the content of the present specification should not be understood as the limitation of the present invention.
