[0036] ​It is known that the conductive row (also known as busbar or busbar row) is used in the power storage device to connect a plurality of batteries or battery modules. Taking the battery module as an example for description: the battery module includes a plurality of battery cells, and the conductive row is used to connect the plurality of battery cells in series or parallel to realize the electrical connection between the plurality of battery cells. On the other hand, the conductive row also needs to collect the battery cells connected in series or parallel into one positive electrode and one negative electrode to be electrically connected with the circuit outside the battery module. At the same time, in order to ensure the stability of the tab of the battery cell and the conductive row, the conductive row is often installed on a specific bracket to fix and support the conductive row.

[0037] The conductive row is usually made of a metal material with high conductivity, such as copper, aluminum, nickel, titanium alloy or magnesium alloy, to ensure efficient transmission of electric energy. However, due to different use scenarios, the material of the conductive row needs to be determined comprehensively according to factors such as conductivity, mechanical strength, corrosion resistance and thermal stability. Therefore, when the use scenario is different, the conductive row needs to be replaced.

[0038] However, in the related art, the conductive row and its corresponding bracket are often fixed by one-piece molding such as injection molding, so that the conductive row cannot be detached from the bracket, and the bracket and the conductive row can only be replaced as a whole, which not only increases the cost, but also causes waste of energy.

[0039] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0040] It should be noted that if the present application embodiments involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), if the specific posture changes, the directional indications will also change accordingly.

[0041] In addition, in the description of the present application, the terms used are only for the purpose of illustration, and are not intended to limit the scope of the present application. The terms "include" and / or "contain" are used to specify the presence of the elements, steps, operations and / or components, but do not exclude the presence or addition of one or more other elements, steps, operations and / or components. The terms "first", "second" and the like can be used to describe various elements, which do not represent the order and do not limit the elements. In addition, in the description of the present application, unless otherwise stated, the meaning of "multiple" is two and more than two. These terms are only used to distinguish one element from another. These and / or other aspects become apparent from the following drawings, and those skilled in the art can more easily understand the description of the embodiments described in the present application. The drawings are only used to depict the embodiments described in the present application for illustrative purposes. Those skilled in the art will easily realize from the following description that alternative embodiments of the structures and methods shown in the present application can be used without departing from the principles of the present application.

[0042] The support assembly described in the embodiments of the present application comprises a first conductive row 21, a second conductive row 22 and a support 1. Among them, the first conductive row 21 can be used for electrical connection between the tab of the battery cell and the external circuit, for example; the second conductive row 22 can be used for electrical connection between the tabs of the adjacent two battery cells, for example. It is easy to understand that the first conductive row 21 can include two, one as the positive electrode of the battery cell group, and the other as the negative electrode of the battery cell group. The first conductive row 21 and the second conductive row 22 are installed on the support 1 to realize the support and fixation of the first conductive row 21 and the second conductive row 22.

[0043] For ease of understanding, the X-axis in the drawings of the present application is the length direction of the support assembly, the Y-axis is the width direction of the support assembly, and the Z-axis is the height direction of the support assembly.

[0044] As shown in Figure 1 and Figure 3 The first conductive row 21 comprises a first plate body 211 and a second plate body 212 arranged at an angle; the support 1 comprises a platform part 11 and a main body part 12 arranged at an angle. For example, the angle between the first plate body 211 and the second plate body 212 is A, and the angle between the platform part 11 and the main body part 12 is B. The values of A and B are both 0-180°, and the values of A and B can be the same or different.

[0045] Preferably, the values of A and B are the same, for example, the values of A and B can be 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110° or 120°, etc.

[0046] More preferably, the values of A and B are both 90°, that is, the first plate body 211 and the second plate body 212 are perpendicular to each other; the platform portion 11 and the main body portion 12 are perpendicular to each other, and then the first plate body 211 is parallel to the main body portion 12, and the second plate body 212 is parallel to the platform portion 11. Thus, when the first conductive row 21 is installed on the support 1, not only the first plate body 211 and the main body portion 12 are in close contact, but also the second plate body 212 and the platform portion 11 can be in close contact, thereby improving the stability of the first conductive row 21 installed on the support 1.

[0047] Please refer to Figures 3-4 The first surface of the main body portion 12 is formed with a first recess 121, and the second surface of the main body portion 12 is adjacent to the first surface and is provided with a plug-in interface 122 communicating with the first recess 121, and the bottom wall of the first recess 121 is provided with a clamping portion, and the platform portion 11 is located at the plug-in interface 122; the first plate body 211 passes through the plug-in interface 122 and extends into the first recess 121, and the clamping portion is detachably connected with the first plate body 211, and the second plate body 212 is located on the side of the platform portion 11 away from the main body portion 12, and the second plate body 212 is detachably connected with the platform portion 11.

[0048] The first surface of the main body portion 12 is, for example, the upper surface of the main body portion 12, and the second surface of the main body portion 12 is, for example, the right side surface connected with the upper surface thereof. The first recess 121 is provided on the upper surface of the main body portion 12 and is matched in shape and size with the first conductive row 21. The first recess 121 is provided with two, for example, for placing the first conductive row 21 corresponding to the positive and negative electrodes. In this way, the first recess 121 can play a certain limiting role on the first conductive row 21, avoiding the first conductive row 21 from shaking on the support 1, and further improving the stability of the first conductive row 21 on the support 1.

[0049] As described above, the plug-in interface 122 is provided on the right side surface of the main body portion 12 and communicates with the first recess 121, and the platform portion 11 is located at the plug-in interface 122. Specifically, the plug-in interface 122 communicates with the rightmost end of the first recess 121, and the platform portion 11 is located at the rightmost end of the support 1 and extends a certain height upward perpendicular to the main body portion 12. The plug-in interface 122 penetrates the platform portion 11, so that the first plate body 211 can be inserted into the support 1 from the right side of the support 1 through the plug-in interface 122 and extend into the first recess 121 on the upper surface of the main body portion 12. At the same time, the second plate body 212 is located on the right side of the platform portion 11 due to the blocking of the platform portion 11 and abuts against the right side surface of the platform portion 11 to play a certain limiting or fixing role on the first conductive row.

[0050] Please refer to Figures 3-4A clamping portion is arranged on the bottom wall of the first groove 121, for example, a clamping portion is arranged on the surface of the first groove 121 facing the first plate body 211, for detachable connection between the first plate body 211 and the main body 12. The clamping portion can be a buckle, for example, to achieve detachable connection between the first plate body 211 and the main body 12 by clamping. The clamping portion can also be arranged as other structures capable of achieving detachable connection in addition to buckles, such as magnetic attraction, riveting, etc., which are not limited in the present application.

[0051] At the same time of achieving detachable connection between the first plate body 211 and the main body 12, the second plate body 212 and the platform 11 are also connected in a detachable manner. Thus, when different materials of the first conductive row are required due to different use scenarios or performance requirements, the first conductive row 21 can be disassembled and replaced, avoiding the situation that the first conductive row 21 cannot be disassembled from the support 2, causing the entire support assembly to be invalid, effectively reducing the maintenance cost.

[0052] In an optional embodiment, the clamping portion includes a clamping column 123, and a strip-shaped hole 124 is arranged on the bottom wall of the first groove 121, and the strip-shaped hole 124 is arranged on the side of the clamping column 123; the first plate body 211 is provided with a groove or a first through hole 213 matched with the clamping column 123.

[0053] Specifically, as shown in Figures 1-4 The clamping column 123 is arranged on the upper surface of the main body 12, for example, and the clamping portion is located on the side of the main body 12 away from the plug-in port 122. It can be understood that the clamping column 123 has a certain height, that is, the clamping column 123 extends a certain height along the height direction of the support assembly, so as to be inserted into the corresponding groove or first through hole 213 of the first plate body 211. For example, the clamping column 123 is inserted into the first through hole 213, so that the first plate body 211 can be fixed, avoiding the first plate body 211 from sliding along the upper surface of the main body 12 and then being pulled out of the plug-in port 122. That is, when the first plate body 211 is located in the first groove 121, the clamping column 123 will be inserted into the first through hole 213 of the first plate body 211, and through the cooperation of the first groove 121, the clamping column 123 and the first through hole 213, the first conductive row 21 can be stably fixed on the main body 12, and the clamping column 123 and the first through hole 213 can also achieve detachable connection between the first conductive row 21 and the main body 12.

[0054] It can be understood that the first conductive row 21 is inserted from the plug-in interface 122 through the first plate body 211 and moves along the direction of the first groove 121 on the upper surface of the main body part 12. When the first plate body 211 contacts the clamping column 123, a greater external force is required to make the first plate body 211 continue to move against the resistance of the clamping column 123. In this process, the clamping column 123 is deformed by the force of the first plate body 211, and the corresponding position of the main body part 12 is deformed. The strip-shaped hole 124 is arranged on the side of the clamping column 123, so that the main body part 12 at the position of the clamping column 123 is connected with the main body part 12 at the surrounding position. In this way, the clamping column 123 is more likely to deform when subjected to the force of the first plate body 211, thereby reducing the external force required to overcome the resistance of the clamping column 123. In addition, the deformation amount of the main body part 12 can be reduced to some extent, thereby prolonging the service life of the support.

[0055] Preferably, the end of the clamping column 123 away from the bottom wall is provided with an inclined surface. It can be understood that the inclined surface is arranged at the upper end of the clamping column 123, which can be an inclined surface inclined toward the plug-in interface, that is, the inclined direction of the inclined surface is arranged in the same direction as the moving direction of the first plate body 211. When the first plate body 211 contacts the clamping column 123 and continues to move toward the clamping column 123, the clamping column 123 can more easily slide into the first through hole 213 under the action of the inclined surface, further reducing the resistance of the clamping column 123 to the first plate body 211.

[0056] Further, the strip-shaped hole 124 is U-shaped, and the two ends of the strip-shaped hole 124 extend toward the plug-in interface.

[0057] Continuing to refer to Figures 3-4 The strip-shaped hole 124 is U-shaped, and it can be understood that the strip-shaped hole 124 is arranged on three sides around the clamping column 123, for example, the strip-shaped hole 124 is arranged at the upper side, the left side and the lower side of the clamping column 123. The clamping column 123 is fixedly connected with the main body part 12 only through the right side. Thus, the resistance of the clamping column 123 can be reduced as much as possible, so that the clamping column 123 can be deformed under the action of a smaller force and enter the first through hole 213 under the action of its own elastic force. In use, the strip-shaped hole 124 can also be arranged in other shapes as long as the resistance of the clamping column 123 can be reduced, and the shape of the strip-shaped hole 124 is not limited in the present application.

[0058] In an alternative embodiment, the support 1 assembly further comprises a detection module, which comprises an electrically connected detection unit 3 and a wire harness 4; the bottom wall of the first groove 121 is provided with a second through hole 126, and at least part of the detection unit 3 is located in the second through hole 126 and contacts the first plate body 211.

[0059] Please refer to Figures 3-6It is known that the electrode tab of the battery cell can extend through the opening 129 through the main body 12 to the top of the first conductive bus 21, and be welded to the first conductive bus 21 after appropriate bending. In this application, the electrode tab of the battery cell is welded to its corresponding first plate 211. By contacting the detection unit 3 with the first plate 211 through the second through hole 126 provided on the bottom wall of the first groove 121, an electrical connection between the detection unit 3 and the electrode tab can be achieved, thereby detecting information such as the current, voltage, or temperature of the electrode tab for battery cell control.

[0060] It is readily understood that the detection unit 3 can be, for example, a sensor or a thermistor. During use, the type of detection unit 3 can be adaptively selected based on the information to be detected, and is not limited to the types of detection units 3 listed above. The detection unit 3 can be bonded to the first plate 211, for example, using conductive adhesive, to improve the stability of the connection between the detection unit 3 and the first plate 211, avoiding errors or inconsistencies in the detection structure due to unstable connections. Of course, other methods can also be used to achieve the connection between the detection unit and the first plate 211; this application does not specifically limit its application.

[0061] The wiring harness 4 can be understood as a collection of signal lines connected to multiple detection units 3. The detection unit 3 can be connected to the circuit board through the wiring harness 4. The circuit board can be, for example, a BMS protection board, so as to transmit the information such as current, voltage or temperature detected by the detection unit 3 to the BMS protection board, thereby controlling the working state of the battery cell.

[0062] Preferably, a plurality of partitions 14 are provided on a second surface of the main body 12 that is away from the first surface, and the extension direction of the plurality of partitions 14 is the same as the extension direction of the first plate 211; in the orthographic projection of the first surface, the first conductive busbar 21 and the plurality of partitions 14 do not overlap.

[0063] by Figures 5-6 Taking an example, the second surface of the main body 12 can be understood as the lower surface (or back surface) of the main body 12. Multiple partitions 14 are provided on the lower surface of the main body 12, and the length direction of the partitions 14 is parallel to the length direction of the first plate 211. Alternatively, the partitions 14 and the first plate 211 can be understood as corresponding and compatible. For example, two opposing partitions 14 can correspond to one first plate 211, and the detection unit 3 in contact with the first plate 211 and / or the signal line connected to the detection unit 3 is located between the two opposing partitions 14 to isolate adjacent detection units 3 and signal lines, achieving insulation and preventing short circuits between cells or mutual interference between signals caused by contact between adjacent detection units 3.

[0064] The length of the partition plate 14 can be determined according to the length of the first plate body 211, for example. The length of the partition plate 14 can be equal to or slightly smaller than the length of the first plate body 211, for example, so that the partition plate 14 can isolate the adjacent detection units 3 and also isolate the tabs of the adjacent battery cells, to avoid the risk of contact between the tabs of the adjacent battery cells and thus short circuit. The gap between the two oppositely arranged partition plates 14 can be determined according to the size of the detection unit 3. The gap between the two partition plates 14 can be slightly larger than the width of the detection unit 3, to facilitate the connection between the detection unit 3 and the first plate body 211.

[0065] At the same time, it can be understood that the baffle 14 at the position where the detection unit 3 and the signal line are connected can be provided with an appropriately sized notch to form a clearance space, to facilitate welding or other operations between the detection unit 3 and the signal line.

[0066] More preferably, the main body 12 further comprises a plurality of wire clamps 127, which are arranged at intervals on the first surface and / or the second surface; and / or, the main body 12 is provided with a notch 13, which is located on the side of the main body 12 away from the platform 11.

[0067] Referring to Figures 3-6 A plurality of wire clamps 127 are arranged on the upper surface and the lower surface of the main body 12. The wire clamps 127 arranged on the lower surface of the main body 12 can be used to fix the signal lines connected to the detection units 3, or can be used to fix the wire harness 4 after the plurality of signal lines are gathered, so that the plurality of signal lines are located between the two partition plates corresponding to the signal lines and are finally gathered into the wire harness 4. For example, the plurality of wire clamps 127 arranged on the lower surface of the main body 12 can be arranged at the end of the partition plate 14 and / or between the two adjacent partition plates 14, to define the direction of the signal lines or the wire harness 4.

[0068] The plurality of wire clamps 127 arranged on the upper surface of the main body 12 can be used to fix the wire harness 4 located on the upper surface of the main body 12, to ensure the direction of the wire harness 4. The plurality of wire clamps 127 arranged on the upper surface of the main body 12 can be arranged near the upper edge or the lower edge of the upper surface of the main body 12, for example, so that the wire harness 4 passes from the edge of the main body 12, to avoid interference between the wire harness 4 and the first conductive row 21 and / or the second conductive row 22 on the upper surface of the main body 12.

[0069] In use, the arrangement position of the wire clamp 127 can be adaptively selected according to the specific requirements or arrangement scheme of the signal line or the wire harness 4, and is not limited to the arrangement modes listed above. The arrangement mode of the wire clamp 127 is not limited in the present application.

[0070] As Figures 3-4As shown, a notch 13 is provided on the side of the main body 12 away from the insertion interface 122. For example, it can be understood that the notch 13 is provided at the middle position of the left edge of the main body 12. Thus, the wire harness 4 located on the lower surface of the main body 12 can pass through the notch 13 to the upper surface of the main body 12. The notch 13 forms a clearance space for the wire harness 4, so that the size of the support assembly will not increase due to the passage of the wire harness 4, at least not increasing the size of the support assembly in the length direction. This is conducive to reducing the volume of the energy storage device, and thus conducive to improving the energy density of the energy storage device.

[0071] In one optional embodiment, the support assembly further includes a second conductive bus 22 and a second groove 128. The second conductive bus 22 is located within the second groove 128, which is formed on a first surface and parallel to the first groove 121. A plurality of positioning posts 125 integrally formed with the main body 12 are provided on the first surface, and the second conductive bus 22 is fixedly connected to the main body 12 through the plurality of positioning posts 125. And / or a connecting post 111 is provided on the side of the platform portion 11 facing away from the main body 12, and a third through hole 214 is provided on the second plate 212. The second plate 212 is detachably connected to the platform portion 11 through the connecting post 111 and the third through hole 214.

[0072] by Figures 1-3 For example, the second conductive busbar 22 is parallel to the first conductive busbar 21, and the second groove 128 is parallel to the first groove 121. The second groove 128 is also provided on the upper surface of the main body 12. The second conductive busbar 22 is disposed in the second groove 128 to limit the movement of the second conductive busbar 22 on the surface of the main body 12.

[0073] The second conductive bus 22 can be used for connecting adjacent battery cells, such as to realize series and / or parallel connections between adjacent cells. The placement of the second conductive bus 22 can be determined according to the arrangement and connection method between adjacent battery cells, and this application does not impose specific limitations on it.

[0074] Furthermore, a plurality of positioning posts 125 are provided on the upper surface of the main body 12, and the plurality of positioning posts 125 and the main body 12 can be integrally injection molded. Each second groove 128 can be provided with two positioning posts 125, and the two positioning posts 125 are respectively located at the left and right ends of the second groove 128. The left and right ends of the second conductive bus 22 are provided with insertion holes adapted to the two positioning posts 125, and the two positioning posts 125 pass through the corresponding insertion holes to fix the second conductive bus 22. For example, a riveting structure is provided at the end of the positioning post 125 away from the main body 12, that is, the size of this end is larger than the size of the insertion hole, so as to prevent the second conductive bus 22 from coming out of the end of the positioning post 125.

[0075] The platform section 11, facing away from the main body section 12, can be understood as having a connecting post 111 on its right side.
