[0037] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.

[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] In related technologies, in order to collect the electrical signals of the battery cells of the battery pack, connecting plates are set at both ends of the battery cells of the battery pack. A unified wiring port is set on one end of the connecting plate for welding the sampling line. Thermistors are scattered around the battery pack and connected to the sampling line at the same time. The entire battery pack uses a single sampling board to collect the electrical signals of the battery cells and is fixed on one side of the bracket of the battery pack. A single sampling line interface is set on the sampling board, and the sampling line is uniformly connected by a connector to realize the electrical signal collection of the battery cells.

[0040] However, in the above-mentioned related technologies, the sampling line interface on the sampling board is relatively simple, the internal space of the battery pack is relatively small, the structure is relatively complex, and the installation positions of the connecting plates and thermistors are relatively hidden. It is necessary to first connect the sampling line to the unified wiring port of the connecting plates connected to the two ends of the battery cell, and then connect it to the thermistor on the peripheral side of the battery cell to bypass the battery cell or pass through the bracket to connect to the sampling line interface. The path that the sampling line needs to pass through is relatively long, and it is easy to be crushed by the battery bracket or the battery cell to form a short circuit.

[0041] In view of this, please refer to Figure 1 and Figure 2 The present application provides a battery pack 100. The battery pack 100 includes a mounting bracket 10, a battery cell 30, and a sampling assembly 50. The battery cell 30 is disposed on the mounting bracket 10. The sampling assembly 50 is disposed on the mounting bracket 10 and is located at at least one end of the battery cell 30 in the axial direction. The sampling assembly 50 is electrically connected to the electrode terminal 31 of the battery cell 30.

[0042] Specifically, the battery cell 30 can be arranged on the mounting bracket 10 by means of a snap fit, so that the battery cell 30 can be easily installed and removed, and the mounting bracket 10 can prevent the battery cell 30 from swaying in the axial position and moving radially. The sampling component 50 can be arranged on the mounting bracket 10 by means of a screw connection or a snap fit and is located at at least one end of the axial direction of the battery cell 30, and is electrically connected to the electrode terminal 31 of the battery cell 30, so that the sampling component 50 can collect the electrical signal of the battery cell 30.

[0043] In one embodiment, when the battery cell 30 is set on the mounting bracket 10, the sampling components 50 can be respectively set at one axial end of the battery cell 30 and contact and connect with the electrode terminal 31 of the battery cell 30, so as to reduce the wiring length inside the battery pack 100 while facilitating the sampling components 50 to collect the electrical signals of the battery cell 30.

[0044] In another embodiment, when the battery cell 30 is set on the mounting bracket 10, the sampling components 50 can be respectively set at both ends of the axial direction of the battery cell 30 and contact and connect with the electrode terminals 31 of the battery cell 30, so as to further reduce the wiring length inside the battery pack 100 and facilitate the sampling component 50 to collect the electrical signal of the battery cell 30.

[0045] It should be noted that the mounting bracket 10 can be made of thermally conductive nylon or other materials with high thermal conductivity and excellent thermal radiation performance, so that the production process is relatively simple and the production cost can be reduced. The sampling component 50 can be made of copper or other materials with good electrical conductivity, so that the component can accurately collect the electrical signal of the battery cell 30.

[0046] It can be understood that, in the related art, when the sampling board is connected to the connecting piece, the sampling line on the sampling board has only one connector, which leads to the elongation and confusion of the routing of the sampling line. The sampling line is easily crossed and squeezed by the battery cell and the bracket during routing, resulting in the excessive attachment of the sampling line to the battery cell when the battery cell is working at full power and the temperature of the battery cell rises. There is a risk of softening and accumulation of the wire and carbonization at high temperature, which leads to the risk of short circuit of the sampling line after carbonization. In the embodiment of the present application, the sampling assembly 50 is arranged at at least one end of the axial direction of the battery cell 30, so that when the sampling assembly 50 is electrically connected to the battery cell 30, the sampling line 55 of the sampling assembly 50 is When routing, the sampling line can be directly connected vertically to the electrode terminal 31 of the battery cell 30. Compared with the related art, there is no need to significantly bypass the battery cell 30 group or pass through the bracket. In the process of connecting the battery cell 30, the sampling line is not easy to be squeezed by the battery cell 30 and the bracket due to crossing. Therefore, the implementation method of the present application can shorten the routing length of the sampling line 55 inside the battery pack 100, reduce the effective area of ​​the sampling line 55 directly contacting the battery cell 30, improve the safety of collection, reduce the possibility of the sampling line 55 being entangled, crossed and squeezed, reduce the risk of short circuit of the sampling line 55 after carbonization of the wire, and manual welding is relatively simple.

[0047] In this way, the battery pack 100 of the embodiment of the present application sets the sampling component 50 on the mounting bracket 10 and is located at at least one end of the axial direction of the battery cell 30, and is electrically connected to the electrode of the battery cell 30, so that the battery cell 30 can be coaxial with the sampling component 50 in the vertical direction, shortening the routing length of the sampling line 30 inside the battery module, while not being easily crushed by the mounting bracket 10 or the battery cell 30 to form a short circuit, and the collection safety is higher.

[0048] See also Figure 2In some embodiments, the mounting bracket 10 includes a first bracket 11 and a second bracket 13 that cooperates with the first bracket 11 and is detachable, and the battery cell 30 is disposed between the first bracket 11 and the second bracket 13. That is, the first bracket 11 can be detachably connected to the second bracket 13 by snapping, screwing, or snapping and screwing. The battery cell 30 can be disposed between the first bracket 11 and the second bracket 13, so that the electrode terminals 31 of the battery cell 30 are respectively located in the mounting holes of the first bracket 11 and the second bracket 13, so that the electrode terminals 31 of the battery cell 30 are electrically connected to the sampling assembly 50. It should be noted that the number of battery cells 30 inserted in the first bracket 11 and the second bracket 13 can be one or more. When the number of battery cells 30 is multiple, it can be 2, 4, 6, 8, 12, 14, 16, 18, 20, 22, 24, 26, 28 or 30, etc., which is not limited here.

[0049] Please combine Figures 2 to 4 In some embodiments, a first mounting plane 111 is provided on the first bracket 11. A second mounting plane 131 opposite to the first mounting plane 111 is provided on the second bracket 13. The second mounting plane faces away from the first bracket 11. The sampling assembly 50 includes a connecting piece 51. The connecting piece 51 is respectively provided on the first mounting plane 111 and the second mounting plane 131 along the axial direction of the battery cell 30, and is electrically connected to the electrode terminal 31 of the battery cell 30.

[0050] Specifically, a first mounting plane 111 may be provided on a side of the first bracket 11 away from the battery cell 30, so that the connecting piece 51 can be mounted flatly on the first mounting plane 111 along the axial direction of the battery cell 30 in a snap-fit ​​or screw-fit manner. A second mounting plane 131 may be provided on a side of the second bracket 13 opposite to the first mounting plane 111, so that the second mounting plane 131 is away from the first bracket 11, so that the connecting piece 51 can be mounted flatly on the second mounting plane 131 along the axial direction of the battery cell 30 in a snap-fit ​​or screw-fit manner.

[0051] In one embodiment, the electrode terminal 31 of the battery cell 30 may include a positive terminal 311 and a negative terminal 313. The number and shape of the connecting pieces 51 disposed on the first mounting plane 111 and the second mounting plane 131 are related to the arrangement of the positive terminal 311 and the negative terminal 313 on the same side of the battery cell 30. That is, if the positive terminal 311 and the negative terminal 313 on the same side of the battery cell 30 are as follows: Figure 2 As shown in the arrangement, four connecting pieces 51 corresponding to the arrangement of the positive terminal 311 and the negative terminal 313 can be respectively provided on the first mounting plane 111 and the second mounting plane 131, and each connecting piece 51 is connected to the positive terminal 311 and the negative terminal 313 of the corresponding battery cell 30, so that the subsequent sampling component 50 can collect the electrical signal of the battery cell 30.

[0052] It should be noted that Figure 2 The arrangement of the positive terminal 311 and the negative terminal 313 on the same side of the battery cell 30, and the number and shape of the connecting piece 51 are only for illustration. The arrangement of the positive terminal 311 and the negative terminal 313 on the same side of the battery cell 30, and the number and shape of the connecting piece 51 can be set according to the actual application situation, and are not limited here. The connecting piece 51 can be stamped from copper material and made by a tin plating process to facilitate soldering connection between the connecting piece 51 and the sampling line 55. The connecting piece 51 can play the role of connecting multiple battery cells 30 in parallel to increase the current of the battery pack 100 and to increase the voltage in series.

[0053] It is understandable that if Figure 1 In the related art, the connecting piece 1 provided on the battery cell 7 is relatively large in size, which makes it inconvenient to disassemble and transport the connecting piece 1. However, in the embodiment of the present application, according to the arrangement of the positive terminal 311 and the negative terminal 313 on the same side of the battery cell 30, a plurality of connecting pieces 51 of corresponding smaller sizes are provided, which can facilitate the disassembly and transportation of the connecting piece 51.

[0054] Please combine Figure 1 and Figure 5 In some embodiments, the sampling assembly 50 further includes a sampling plate 53 and a sampling line 55. The sampling plate 53 is disposed on the first bracket 11. The connecting piece 51 disposed on the first mounting plane 111 is located between the first mounting plane 111 and the sampling plate 53. The connecting piece 51 is electrically connected to the sampling plate 53 through the sampling line 55. That is, the sampling plate 53 can be detachably disposed on the first bracket 11 by snapping or screwing. The connecting piece 51 disposed on the first mounting plane 111 can be located between the first mounting plane 111 and the sampling plate 53, so that the connecting piece 51 and the sampling plate 53 are parallel to each other in the axial direction of the battery cell 30, so that when the connecting piece 51 is electrically connected to the sampling plate 53 through the sampling line 55, the sampling line 55 can be routed along the axial direction of the battery cell 30, shortening the routing length of the sampling line 55 inside the battery module, reducing the effective area of ​​the sampling line 55 directly contacting the battery cell 30, and improving the safety of the collection.

[0055] It should be noted that the sampling line 55 can be a sampling line 55 of model UL3385 AWG22, or other types of sampling lines 55 that meet current carrying requirements and certification requirements, ensure insulation and voltage resistance, and meet the requirements of the use environment. There is no limitation here.

[0056] Please combine Figure 5 and Figure 6In some embodiments, a positioning portion 113 is provided on the first bracket 11 . A positioning hole 531 is provided on the sampling plate 53 . The positioning portion 113 is passed through the positioning hole 531 to set the sampling plate 53 on the first bracket 11 .

[0057] That is, the positioning portion 113 can be provided on the first bracket 11 in an integrated manner to reduce production costs. The sampling plate 53 can be provided with a positioning hole 531 corresponding to the positioning portion 113. When the sampling plate 53 is set on the first bracket 11, the positioning portion 113 can be passed through the positioning hole 531, so that the sampling plate 53 can be detachably set on the first bracket 11. It should be noted that, on the basis of setting the sampling plate 53 on the first bracket 11 through the positioning portion 113 and the positioning hole 531, the sampling plate 53 can also be set on the first bracket 11 by screws, so that the sampling plate 53 is locked on the first bracket 11, so that the sampling plate 53 is more firmly set on the first bracket 11.

[0058] Please combine Figure 3 and Figure 5 In some embodiments, a circumferential side of the first bracket 11 is provided with an avoidance groove 115, and the avoidance groove 115 is used to avoid the sampling line 55 when the connecting piece 51 is electrically connected to the sampling plate 53 through the sampling line 55. That is, one or more avoidance grooves 115 may be provided on the circumferential side of the first bracket 11. When the connecting piece 51 is connected to the sampling plate 53 through the sampling line 55, the sampling line 55 can pass through the avoidance groove 115 to electrically connect the connecting piece 51 and the sampling plate 53, so that the sampling line 55 can be routed vertically along the axial direction of the battery cell 30, without having to bypass the first bracket 11 from the circumferential side of the first bracket 11 and then route, thereby reducing the routing length of the sampling line 55, reducing the possibility of the sampling line 55 being entangled, crossed and squeezed, and improving the safety of collection. It should be noted that when a plurality of avoidance grooves 115 may be provided on the peripheral side of the first bracket 11 , the number of the plurality of avoidance grooves 115 may be, for example, 2, 3, 4, 5, 6, 7 or 8, and is not limited here.

[0059] Please combine Figure 1 and Figure 7 In some embodiments, the connecting piece 51 includes a main body 511 and a pin 513 disposed on the main body 511 , and the pin 513 is electrically connected to the electrode terminal 31 of the battery cell 30 .

[0060] Specifically, the main body 511 and the pins 513 may be integrally formed to reduce production costs. The contact surface of the pins 513 disposed on the main body 511 may be lower than the contact surface of the main body 511 in contact with the mounting bracket 10, so that the pins 513 pass through the first bracket 11 or the second bracket 13 to contact the electrode terminals 31 of the battery cells 30. The number of pins 513 disposed on the main body 511 corresponds to the number of battery cells 30, that is, when, for example, the number of battery cells 30 disposed on the mounting bracket 10 is multiple, the number of pins 513 disposed on the main body 511 may also be multiple.

[0061] In one embodiment, when the connecting piece 51 is disposed on the first mounting plane 111 of the first bracket 11 , the pin 513 can pass through the first mounting hole on the first bracket 11 to contact and connect with the electrode terminal 31 of the battery cell 30 .

[0062] In another embodiment, when the connecting piece 51 is disposed on the second mounting plane 131 of the second bracket 13 , the pin 513 can pass through the second mounting hole on the second bracket 13 to contact and connect with the electrode terminal 31 of the battery cell 30 .

[0063] Please combine Figure 1 , Figures 5 to 7 In some embodiments, a welding hole 533 is provided on the sampling plate 53 , and the welding hole 533 corresponds to the interface 515 on the connecting piece 51 along the axial direction of the battery cell 30 , and the sampling line 55 is electrically connected to the sampling plate 53 through the welding hole 533 .

[0064] Specifically, a welding hole 533 may be provided at a position of the sampling plate 53 corresponding to the interface 515 on the connecting piece 51 along the axial direction of the battery cell 30. A tin point 535 corresponding to the welding hole 533 may be provided near the welding hole 533 on the sampling plate 53 to prevent the risk of short circuit caused by the sampling line 55 being routed on the sampling plate 53.

[0065] In one embodiment, when the connecting piece 51 is connected to the sampling plate 53 through the sampling line 55, one end of the sampling line 55 can be welded to the interface 515 on the connecting piece 51, and the other end of the sampling line 55 can pass through the welding hole 533 and be welded to the tin point 535 near the welding hole 533. It should be noted that the welding hole 533 can be Figure 6 The slot 5331 and through hole 5333 are shown.

[0066] In some embodiments, the sampling plate 53 is provided with a welding mark 537 at the periphery of the welding hole 533, and the welding mark 537 is used to identify the routing and welding position of the sampling line 55. Fig. 9As shown, the sampling plate 53 may be printed with a welding mark 537 at the periphery of the welding hole 533. The welding mark 537 may be pure numbers, pure letters, pure Chinese characters, or a combination of letters and numbers. When the user is routing, the corresponding sampling line 55 may be passed through the welding hole 533 and welded to the corresponding tin point 535 according to the welding mark 537 on the sampling plate 53, which facilitates the routing and welding position identification of the sampling line 55. Manual welding is relatively simple, and welding misalignment is not likely to occur, thereby improving the accuracy and efficiency of welding.

That is, the second bracket 13 can be engaged with the first bracket 11 through the buckle 133, and the screw is screwed to the first bracket 11 through the screw mounting column 135, so that the first bracket 11 and the second bracket 13 are locked and connected, so that the connection between the first bracket 11 and the second bracket 13 is more firmly.

[0068] Please combine Figure 1 , Figure 3 and Figure 4 In some embodiments, a first mounting hole 117 is provided on the first bracket 11 , a second mounting hole 137 matching with the first mounting hole 117 is provided on the second bracket 13 , and the battery cell 30 is passed through the first mounting hole 117 and the second mounting hole 137 .

[0069] Specifically, the first bracket 11 may be provided with a plurality of first mounting holes 117, and the second bracket 13 may be provided with a second mounting hole 137 that matches the first mounting hole 117. The first mounting holes 117 provided on the first bracket 11 and the second mounting holes 137 provided on the second bracket 13 may correspond to the number of the battery cells 30. That is, for example, when the number of the battery cells 30 is 10, the first mounting holes 117 provided on the first bracket 11 and the second mounting holes 137 provided on the second bracket 13 may also be 10, so that the 10 battery cells 30 can be respectively passed through the corresponding first mounting holes 117 and the second mounting holes 137 and arranged on the mounting frame, and at the same time, it is convenient for the pins 513 of the connecting piece 51 to pass through the first mounting holes 117 or the second mounting holes 137 to contact and connect with the electrode terminals 31 of the battery cells 30.

[0070] It should be noted that Figure 6 The number and Figure 7The number of second mounting holes 137 set on the second bracket 13 shown is only for example. The number of first mounting holes 117 set on the first bracket 11 and the number of second mounting holes 137 set on the second bracket can be set according to the actual number of battery cells 30, and are not limited here.

[0071] In summary, it should be noted that the battery pack 100 may include one or more battery modules 200. Each battery module 200 may be composed of a first bracket 11, a second bracket 13, one or more battery cells 30 inserted through the first bracket 11 and the second bracket 13, a connecting piece 51 disposed on the first plane of the first bracket 11, a connecting piece 51 disposed on the second plane of the second bracket 13, and a sampling plate 53 disposed on the first bracket 11.

[0072] In one embodiment, when the battery pack 100 includes a plurality of battery modules 200, for example, two battery modules 200 may be included. The installation process of the battery pack 100 is as follows:

[0073] First, if Figure 8 As shown, the battery cell 30 is installed in the first bracket 11 and the second bracket 13 of each battery module 200, respectively. At this time, the first bracket 11 and the second bracket 13 can be detachably connected by using the buckle 133 and the first screw 15 and the screw mounting column 135. Then, as Fig. 9 As shown, the connecting pieces 51 are respectively arranged at both ends of the battery cells 30 of the two battery modules 200 and connected to the electrode terminals 31 of the battery cells 30, and one end of the sampling line 55 is connected to the interface 515 of the connecting piece 51. Then, as shown in FIG. Fig.10 As shown, the sampling plate 53 can be respectively set on the first bracket 11 of the two battery modules 200 by the second screw 17, and the other end of the sampling line 55 can pass through the slot 5331 or the through hole 5333 and be welded to the corresponding position of the sampling plate 53 according to the welding mark 537. Fig.11 As shown, the second brackets 13 of the two battery modules 200 can fit together on one side away from the first bracket 11. At this time, the third screws 19 can be passed through the mounting brackets 10 of the two battery modules 200 in sequence to detachably connect the two battery modules 200, thereby completing the assembly of the battery pack 100.

[0074] It should be noted that when the connecting piece 51 is connected to the sampling plate 53 through the sampling line 55, if one end of the sampling line 55 is located between the two battery modules 200, the other end of the sampling line 55 can be routed along the periphery of the battery module 200, so that the other end of the sampling line 55 can subsequently pass through the cutout 5331 of the sampling plate 53 and then be welded at the corresponding position. If one end of the sampling line 55 is not located between the two battery modules 200, the sampling line 55 can directly pass through the through hole 5333 of the sampling plate 53 and be welded at the corresponding position.

[0075] The first screw 1515 and the second screw 17 can be screws of M3 or above and have a strength of 8.8. The length of the third screw 19 can be greater than the sum of the heights of the two battery modules 200, and the third screw 19 can be screws of M4 or above and have a strength of 8.8.

[0076] The present application also provides a vehicle. The vehicle includes the battery pack 100 described above. The specific structure of the battery pack 100 is as described above, and for the sake of brevity, it will not be repeated here.

[0077] In this way, the vehicle of the embodiment of the present application sets the sampling component 50 on the mounting bracket 10 and is located at at least one end of the axial direction of the battery cell 30, and is electrically connected to the electrode of the battery cell 30, so that the battery cell 30 can be coaxial with the sampling component 50 in the vertical direction, thereby shortening the routing length of the sampling line 30 inside the battery module, and is not easily crushed by the mounting bracket 10 or the battery cell 30 to form a short circuit, thereby increasing the safety of sampling.

[0078] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
