[0006] In certain embodiments, the power connection mechanism includes a support frame and conductive terminals.

[0012] In certain embodiments, the bracket includes a base and a first stopper. The tray is disposed on the base.

[0035] In the description of the embodiments of the present invention, "top" refers to the side of the component facing horizontally upward when the battery or battery cell is in normal use.

[0036] During the battery R&D process, battery cells need to be tested. For example, parameters such as current, voltage, and resistance need to be tested. Only after all performance tests are passed can they be put into production. When testing battery cells, a tray is used to support the battery cells to be tested. The tray and the battery cells are placed on a supporting mechanism to establish an electrical connection between the battery cells to be tested and external testing equipment.

[0037] In the related art, after the tray is placed on the supporting mechanism, wires need to be manually connected between the tray and the external testing device, resulting in low electrical connection efficiency between the tray and the external testing equipment, and thus low testing efficiency of the battery cells.

[0038] In order to solve the technical problem of low electrical connection efficiency between the tray and the external testing equipment, in the testing device of the embodiment of the present invention, when the battery cell needs to be tested, the battery cell can form a module with the tray and be electrically connected to the power connection mechanism, the electrical adapter mechanism can remain connected to the external testing equipment, and the driving component drives the electrical adapter mechanism to abut or separate from the power connection mechanism, so that the external testing equipment can collect the parameters of the battery cell through the electrical adapter mechanism and the power connection mechanism, so that the testing of the battery cell is automated, and the battery cell does not need to be manually connected to the external testing equipment, thereby improving the testing efficiency of the battery cell.

[0039] It should be pointed out that the battery cell testing process referred to in the present invention refers to the entire process from the time the battery cell is placed on the tray to the time the external testing equipment completes the testing of the battery cell.

[0040] See also Figures 1-4 The testing device 1000 according to the embodiment of the present invention includes a tray 100, an electrical adapter mechanism 300, a drive assembly 400, a carrier mechanism 500, and a guide mechanism 600. The tray 100 is disposed on the carrier mechanism 500. The tray 100 includes a tray body 10 and a power connection mechanism 20 disposed on the tray body 10. The tray body 10 is used to support battery cells 1100, and the power connection mechanism 20 is used to electrically connect to the battery cells 1100. The guide mechanism 600 includes a guide rail 610 and a slider 620 disposed on the guide rail 610. The guide rail 610 is mounted on the carrier plate 510. The electrical adapter mechanism 300 is disposed on the slider 620 and is used to electrically connect to external testing equipment. The drive assembly 400 is connected to the electrical adapter mechanism 300 and is used to drive the electrical adapter mechanism 300 to abut or separate from the power connection mechanism 20.

[0041] Specifically, tray 100 is used to hold battery cells 1100. For example, battery cells 1100 can be secured to tray 100 using fixing elements such as straps, ensuring that the position of tray 100 relative to tray 100 remains stable. Tray body 10 is a load-bearing member that provides support for battery cells 1100. Tray body 10 can be made of metal materials such as stainless steel and aluminum alloy, or plastic.

[0042] The power connection mechanism 20 is an intermediary for achieving electrical connection between the battery cell 1100 and the external testing equipment. In other words, the external testing equipment can achieve electrical connection with the battery cell 1100 through the power connection mechanism 20 .

[0043] The electrical adapter mechanism 300 maintains electrical connection with the external testing equipment. Therefore, during battery testing, after the electrical adapter mechanism 300 abuts the power connection mechanism 20, the battery cell 1100 can be electrically connected to the external testing equipment. The drive assembly 400 can be driven by, but not limited to, electrical drive, fluid drive, and other methods. The drive assembly 400 can drive the power connection mechanism 20 to move and / or rotate.

[0044] The support mechanism 500 can support the tray 100, thereby stabilizing the position of the tray 100 and, in turn, the position of the battery cells 1100, facilitating smooth testing of the battery cells 1100. The support frame 21 can move relative to the support mechanism 500. That is, the drive assembly 400 can drive the support frame 21 to move relative to the support mechanism 500.

[0045] In one example, the battery cell 1100 can be first fixed on the tray 100 and then transferred to the supporting mechanism 500 together with the tray 100. Then, the driving component 400 support frame 21 moves relative to the supporting mechanism 500 so that the conductive probe 310 abuts against the conductive terminal 22, thereby collecting and testing the parameters of the battery cell 1100.

[0046] The slider 620 can be slidably mounted on the guide rail 610 and can move linearly on the guide rail 610. Since the support frame 21 is mounted on the slider 620, the movement path of the support frame 21 is also linear. The support frame 21 can be connected to the slider 620 by threading, welding, or other means. The guide rail 610 can be connected to the support plate 510 by threading, welding, or other means. The guide rail 610 and the slider 620 cooperate to guide the movement of the support frame 21 and reduce resistance during the movement of the support frame 21.

[0047] Therefore, when the battery cell 1100 needs to be tested, the battery cell 1100 can form a module with the tray 100 and be electrically connected to the power connection mechanism 20, the electrical adapter mechanism 300 can remain connected to the external testing equipment, and the driving component 400 cooperates to drive the electrical adapter mechanism 300 to abut or separate from the power connection mechanism 20 through the guide rail 610 and the slider 620, so that the external testing equipment can collect the parameters of the battery cell 1100 through the electrical adapter mechanism 300 and the power connection mechanism 20, so that the testing of the battery cell 1100 is automated, and the battery cell 1100 does not need to be manually connected to the external testing equipment, thereby improving the testing efficiency of the battery cell 1100.

[0048] See also Figure 2-Figure 4 In some embodiments, the power connection mechanism 20 includes a support frame 21 and conductive terminals 22. The conductive terminals 22 are disposed on the support frame 21, which is mounted on the tray 10. The conductive terminals 22 are used to electrically connect to the battery cells 1100 and to abut or separate from the power transfer mechanism 300.

[0049] Specifically, the support frame 21 provides support for the conductive terminals 22, ensuring that the conductive terminals 22 remain in a stable position. It will be appreciated that the conductive terminals 22 are conductive elements. Therefore, to reduce the risk of short circuits between the conductive terminals 22, the support frame 21 is generally made of an insulating material. For example, the support frame 21 may be made of plastic. The support frame 21 may be secured to the tray body 10 by screws, adhesive bonding, welding, or other methods.

[0050] The conductive terminal 22 is a conductive member in a sheet, block, or columnar shape. It can be made of a conductive material such as copper. The conductive terminal 22 can be electrically connected to the battery cell 1100's terminal post 1110, the battery housing, and other components. The conductive terminal 22 can be embedded in the support frame 21, with one side of the conductive terminal 22 exposed outside the support frame 21 to facilitate electrical connection.

[0051] In this way, the support frame 21 can provide support for the conductive terminal 22 so that the conductive terminal 22 can be stably electrically connected to the battery cell 1100 .

[0052] In some embodiments, the electrical switching mechanism 300 includes a conductive probe 310 and a mounting frame 320, the conductive probe 310 is set on the mounting frame 320, the mounting frame 320 is set on the slider 620, and the driving assembly 400 is connected to the mounting frame 320 and is used to push the mounting frame 320 to move so that the conductive probe 310 abuts or separates from the conductive terminal 22.

[0053] Specifically, the mounting frame 320 of the electrical switching mechanism 300 provides support for the conductive probes 310, thereby maintaining a stable position of the conductive terminals 22. The mounting frame 320 is generally made of an insulating material, such as plastic. The mounting frame 320 can be connected to the drive assembly 400 via screws, adhesive bonding, welding, or other methods. The mounting frame 320 can be configured as an irregular structure depending on the number and arrangement of the conductive probes 310.

[0054] The conductive probe 310 can be cylindrical. The conductive probe 310 can maintain electrical connection with external testing equipment. After the conductive probe 310 contacts the conductive terminal 22, the battery cell 1100 can be electrically connected to the external testing equipment. In this way, the testing device 1000, through the conductive probe 310 of the electrical adapter mechanism 300 abutting the conductive terminal 22, allows the battery cell 1100 to be electrically connected to the external testing equipment through the conductive terminal 22 and the conductive probe 310, facilitating smooth testing of the battery cell 1100.

[0055] In this way, the mounting frame 320 can provide support for the conductive probe 310, so that the driving assembly 400 can push the support frame 21 to move so that the conductive probe 310 abuts or separates from the conductive terminal 22, so that the electrical adapter mechanism 300 and the power connection mechanism 20 are electrically connected or disconnected to complete the test of the battery cell 1100.

[0056] In some embodiments, there are multiple pairs of conductive probes 310 , which are spaced apart on the mounting frame 320 , and there are multiple pairs of conductive terminals 22 , which are in contact with or separated from corresponding conductive probes 310 .

[0057] It will be appreciated that a pair of conductive terminals 22 includes two conductive terminals 22. Therefore, in the embodiment of the present invention, the number of conductive terminals 22 is at least four. The pair of conductive terminals 22 forms a loop for the acquisition circuit of the battery cell 1100, thereby facilitating the acquisition of parameters of the battery cell 1100. The parameters of the battery cell 1100 include, but are not limited to, temperature, voltage, resistance, and current.

[0058] When the tray 10 carries the battery cell 1100, multiple pairs of conductive terminals 22 can be electrically connected to the battery cell 1100, so that external testing equipment outside the tray 100 can collect multiple parameters of the battery cell 1100 through the multiple pairs of conductive terminals 22, so as to simultaneously test the multiple parameters of the battery cell 1100, thereby improving the testing efficiency of the battery cell 1100.

[0059] See also Figure 3 and Figure 4In some embodiments, the driving assembly 400 includes a cylinder 410 , which includes a fixed portion 411 and a movable portion 412 connected to the fixed portion 411 , and the movable portion 412 is connected to the mounting bracket 320 .

[0060] Specifically, the fixed portion 411 of the cylinder 410 is, for example, a cylinder body, and the movable portion 412 of the cylinder 410 is, for example, a piston rod. The piston rod can move within the cylinder body under the action of gas. The movable portion 412 of the cylinder 410 can be connected to the mounting bracket 320 by threaded connection, bonding, clamping, welding, etc.

[0061] In this way, the cylinder 410 can easily form a linear motion, and the cylinder 410 can be easily controlled, so that the mounting bracket 320 can be driven to move more easily.

[0062] See also Figure 4 and Figure 5 In some embodiments, the carrying mechanism 500 includes a carrying plate 510 and a bracket 520 disposed on the carrying plate 510 , the tray 100 is disposed on the bracket 520 , and the guide rail 610 is installed on the carrying plate 510 .

[0063] Specifically, the support plate 510 is a fundamental component of the support mechanism 500 and provides support for the bracket 520. The support plate 510 can be made of a strong material such as steel or aluminum alloy, so that the support mechanism 500 is not easily deformed when carrying the tray 100 and battery cells 1100. This facilitates accurate contact between the conductive terminals 22 and the conductive probes 310, allowing for smooth testing of the battery cells 1100.

[0064] In this way, the carrier plate 510 can provide support for the bracket 520 , and the bracket 520 can support the tray 100 , thereby stabilizing the position of the tray 100 and allowing the battery cells 1100 to be tested smoothly.

[0065] See also Figure 5 and Figure 6 In some embodiments, the bracket 520 includes a base 521 and a first limiter 522, the tray 100 is set on the base 521, and the first limiter 522 is set on the side of the base 521 away from the driving assembly 400, for limiting the position of the tray 100 in the first direction X.

[0066] Specifically, the base 521 may include two hollow support columns 5211, which are arranged substantially parallel to the carrier plate 510. The first position-limiting member 522 is, for example, a sheet-shaped member. The first position-limiting member 522 may be fixedly connected to the carrier plate 510 or the base 521 by welding or other means to fix the position of the first position-limiting member 522, thereby enabling the first position-limiting member 522 to limit the position of the tray 100.

[0067] For example, when the tray 100 is supported on the base 521, the tray 100 can move in a first direction under the action of an external force. The tray 100 stops when it abuts against the first stopper 522, thus positioning the tray 100 against the first stopper 522. This position allows the tray 100 to be more accurately loaded onto the bracket 520. In the embodiment of the present application, the first direction X is the direction of movement of the support frame 21.

[0068] In this way, the first limiting member 522 can limit the position of the tray 100 in the first direction X, thereby improving the stability of the battery cells 1100 in the first direction during the test process, which is beneficial to the testing of the battery cells 1100.

[0069] See also Figure 5 and Figure 6 In some embodiments, the bracket 520 further includes a second limiter 523, which is arranged on one side of the base 521 along the second direction Y, and is used to limit the position of the tray 100 in the second direction Y, where the second direction Y is perpendicular to the first direction X.

[0070] Specifically, the second limiting member 523 is, for example, a sheet-shaped part, and the second limiting member 523 can be fixedly connected to the supporting plate 510 or the base 521 by welding or other means to fix the position of the second limiting member 523, so that the second limiting member 523 can limit the tray 100.

[0071] In this way, the second limiting member 523 can limit the position of the tray 100 in the second direction Y, thereby improving the stability of the battery cell 1100 in the second direction Y during the test process, which is beneficial to the test of the battery cell 1100.

[0072] See also Figure 5 and Figure 6 In some embodiments, there are multiple brackets 520 , and the multiple brackets 520 are arranged at intervals, and a tray 100 is provided on each bracket 520 .

[0073] Specifically, a plurality of brackets 520 are arranged at intervals along the second direction Y. The number of brackets 520, trays 100, drive assemblies 400, and electrical adapter mechanisms 300 may correspond one to one, so that each drive assembly 400 can move the corresponding electrical adapter mechanism 300 to complete the test of the corresponding battery cell 1100.

[0074] In this way, the cooperation of the multiple brackets 520 and the multiple trays 100 can test the multiple battery cells 1100 at the same time, which is beneficial to improving the testing efficiency of the battery cells 1100.

[0075] like Figure 7 and Figure 8 As shown, in some embodiments, the tray body 10 includes a bottom plate 11 and support bars 12, which are connected to the bottom edge of the bottom plate 11. The support bars 12 are provided on two opposite edges of the bottom plate 11, so that the tray 100 can be more stably placed on the supporting mechanism 500 via the support bars 12. The bottom plate 11 is used to support the battery cells 1100, or in other words, the battery cells 1100 are placed on the bottom plate 11.

[0076] like Figure 7 and Figure 8 As shown, in some embodiments, the support frame 21 may include a body 211 and a connecting piece 212. The connecting piece 212 may be detachably connected to the body 211. For example, the connecting piece 212 may be mounted on the body 211 using screws. A portion of the conductive terminals 22 is disposed on the body 211, and a portion of the conductive terminals 22 is disposed on the connecting piece 212. The size of the conductive terminals 22 on the body 211 is larger than that of the conductive terminals 22 on the connecting piece 212, so that conductive terminals 22 of different sizes can be disposed on different parts, which facilitates stable installation of the conductive terminals 22. The body 211 may be an irregular shape as a whole, so that the body 211 can adapt to the shape of the tray 10.

[0077] In some embodiments, multiple pairs of conductive terminals 22 are arranged in the same direction. In other words, the centers of all conductive terminals 22 are arranged on the same virtual straight line. This simplifies the arrangement of multiple pairs of conductive terminals 22, making the power connection mechanism 20 easier to manufacture and reducing the manufacturing cost of the tray 100. Furthermore, arranging multiple pairs of conductive terminals 22 in the same direction also makes it easier to connect the conductive terminals 22 to the battery cells 1100.

[0078] In some embodiments, at least two pairs of conductive terminals 22 have different flow areas. Specifically, the flow areas of the conductive terminals 22 may be the cross-sectional areas of the conductive terminals 22. It is understood that the larger the flow area of ​​the conductive terminals 22, the greater the flow conductivity of the conductive terminals 22.

[0079] For example, when testing the current of a battery cell 1100, the output current of the battery cell 1100 may be relatively high, thus requiring a conductive terminal 22 with a larger flow area. When testing the temperature of the battery cell 1100, the current generated by the sensor is relatively small, so a conductive terminal 22 with a smaller flow area can be used. Thus, conductive terminals 22 with different cross-sectional areas have different flow capacities, allowing multiple pairs of conductive terminals 22 to meet different parameter testing requirements.

[0080] like Figure 7 and Figure 8For example, among the multiple conductive terminals 22, the conductive terminals 22 located on both sides have a larger conduction area, and the conductive terminal 22 located in the middle has a smaller conduction area.

[0081] In some embodiments, the support frame 21 is connected to the side surface 13 of the tray 10 , the top surface 14 of the tray 10 is configured to support the battery cells 1100 , and the multiple pairs of conductive terminals 22 are located on the side facing the top surface 14 of the tray 10 .

[0082] Specifically, the upper surface of the bottom plate 11 of the tray body 10 forms the top surface 14 of the tray body 10, while the bottom plate 11 and the support bars 12 together form the side surfaces 13 of the tray body 10. The body 211 of the support frame 21 is disposed on the side surfaces 13 of the tray body 10. Multiple pairs of conductive terminals 22 are located on the side of the tray body 10 facing the top surface 14. In other words, all conductive terminals 22 are located above the top surface 14 of the tray body 10.

[0083] During testing, the battery cell 1100 is placed on the top surface 14 of the tray 10, with the bottom of the battery cell 1100 in contact with the top surface 14 of the tray 10, and the terminal 1110 of the battery cell 1100 is located on top of the battery cell 1100. Placing all of the conductive terminals 22 above the top surface 14 of the tray 10 facilitates connection between the conductive terminals 22 and the terminal 1110 of the battery cell 1100.

[0084] Therefore, the support frame 21 is connected to the side surface 13 of the tray body 10, which reduces the space occupied by the support frame 21 on the top surface 14 of the tray body 10, leaving more space on the top surface 14 of the tray body 10 to support the battery cells 1100, thereby miniaturizing the tray body 10. In addition, multiple pairs of conductive terminals 22 are located on the side facing the top surface 14 of the tray body 10, which facilitates the connection between the conductive terminals 22 and the battery cells 1100.

[0085] See also Figure 1 、 Figure 2 and Figure 7 In some embodiments, the conductive terminal 22 includes a conductive surface 221 , which is used to contact the conductive probe 310 , and the conductive surface 221 is perpendicular to the top surface 14 of the disk body 10 .

[0086] Specifically, the conductive surface 221 is the surface of the conductive terminal 22 facing away from the battery cell 1100. The conductive surface 221 can be a flat surface, and its shape includes but is not limited to a circle or a square. The top surface 14 of the tray 10 is generally arranged horizontally to provide greater stability for the battery cell 1100. The conductive surface 221 is perpendicular to the top surface 14 of the tray 10, that is, the conductive surface 221 can be a vertical surface. During the movement of the conductive probe 310, the conductive probe 310 generally moves horizontally, which increases the contact area between one end of the conductive probe 310 and the conductive surface 221.

[0087] Therefore, the conductive surface 221 is perpendicular to the top surface 14 , making the contact between the conductive surface 221 and the conductive probe 310 more stable. The conductive terminal 22 can be electrically connected to an external testing device through the conductive probe 310 , thereby improving the stability of the battery cell 1100 test.

[0088] See also Figure 7 and Figure 8 In some embodiments, the tray 100 includes a wire 30 , one end of which is connected to the conductive terminal 22 , and the other end of which is used to connect to the battery cell 1100 or the sensor.

[0089] Specifically, the wire 30 can be a flexible wire. One end of the wire 30 can be fixedly connected to the conductive terminal 22, for example, by welding the conductive terminal 22. The other end of the wire 30 can be detachably connected to the battery cell 1100, for example, by adhesively securing the wire 30 to the battery cell 1100. The cross-section of the wire 30 matches the current-passing surface of the conductive terminal 22. Thus, the connection between the conductive terminal 22 and the battery cell 1100 via the wire 30 provides a more stable electrical connection.

[0090] The test system of the present invention includes the test device 1000 of any of the above embodiments. The test system may include external test equipment and a transfer device. The transfer device may be, for example, a manipulator or the like.

[0091] In one embodiment, when testing the battery cell 1100, the battery cell 1100 can be first placed on the tray 100 and fixed with a fixing element such as a strap, and then the battery cell 1100 can be connected using a wire 30, or a sensor can be arranged on the battery cell 1100. After that, the tray 100 with the battery cell 1100 can be transferred to the supporting mechanism 500 through a transfer device, and then the driving component 400 drives the electrical adapter mechanism 300 to move so that the conductive probe 310 contacts the conductive terminal 22, so that the test equipment can collect the parameters of the battery cell 1100 to complete the test of the battery cell 1100.
