Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The following describes in detail, with reference to the accompanying drawings, the chemical composition tray 10 according to an embodiment of the present invention.

[0037] Reference Figures 1-6 As shown, the formation and capacity tray 10 includes: a support tray 1, a positive electrode conductive bus, and a negative electrode conductive bus. The support tray 1 has a positive electrode interface 11, a negative electrode interface 12, and multiple cell slots 13. The positive electrode conductive bus has a positive electrode probe contact and multiple positive electrode cell contacts 21. The positive electrode probe contact is located at the positive electrode interface 11. The multiple positive electrode cell contacts 21 correspond one-to-one with the multiple cell slots 13, and each positive electrode cell contact 21 is located in the corresponding cell slot 13. The negative electrode conductive bus has a negative electrode probe contact and multiple negative electrode cell contacts 31. The negative electrode probe contact is located at the negative electrode interface 12. The multiple negative electrode cell contacts 31 correspond one-to-one with the multiple cell slots 13, and each negative electrode cell contact 31 is located in the corresponding cell slot 13.

[0038] Specifically, the carrier tray 1 has multiple cell slots 13, each of which can be used to fix a cell 20. The cell 20 has a cell body 203, a positive electrode tab 201 and a negative electrode tab 202. The positive electrode tab 201 and the negative electrode tab 202 are connected to both sides of the cell body 203. The positive and negative conductive busbars can be conductive copper busbars. The positive and negative conductive busbars can be embedded in the carrier tray 1. The carrier tray 1 is made of insulating material to prevent leakage and short circuit of the capacitance tray 10.

[0039] The positive electrode busbar has a positive electrode probe contact and multiple positive electrode cell contacts 21. Each positive electrode cell contact 21 is connected to the positive electrode probe contact. The multiple positive electrode cell contacts 21 correspond one-to-one with multiple cell slots 13. The positive electrode cell contacts 21 can contact and connect with the positive electrode tabs 201 in the cell slots 13. That is to say, the cell 20 in each cell slot 13 is connected to the positive electrode probe contact through the corresponding positive electrode cell contact 21.

[0040] The negative electrode busbar has a negative electrode probe contact and multiple negative electrode cell contacts 31. Each negative electrode cell contact 31 is connected to the negative electrode probe contact. The multiple negative electrode cell contacts 31 correspond one-to-one with multiple cell slots 13. The negative electrode cell contacts 31 can contact and connect with the negative electrode tabs 202 in the cell slots 13. That is to say, the cell 20 in each cell slot 13 is connected to the negative electrode probe contact through the corresponding negative electrode cell contact 31.

[0041] Meanwhile, the positive probe contact is located at the positive interface 11, and the negative probe contact is located at the negative interface 12. Thus, when the battery cell 20 is being formed and tested, the testing equipment for forming and testing the battery cell 20 only needs to insert the positive probe into the positive interface 11 and make it conductive with the positive probe contact, and insert the negative probe into the negative interface 12 and make it conductive with the negative probe contact, to achieve the connection between the testing equipment and each battery cell 20, so as to carry out the relevant process flow of forming and testing. After the process is completed, the positive probe and the negative probe are retracted. Thus, the testing equipment does not need to set a pair of probes for each battery cell 20 separately, thereby reducing the number of probes and corresponding circuits of the testing equipment.

[0042] According to the formulation and capacity tray 10 of this utility model embodiment, multiple battery cells 20 can be fixed by multiple battery cell slots 13. The positive electrode conductive busbar is connected to each positive electrode tab 201, and the negative electrode conductive busbar is connected to each negative electrode tab 202. The testing equipment can be connected to the positive copper sheet through the positive interface 11 and to the negative copper busbar through the negative interface 12, so as to facilitate the electrical connection between the testing equipment and each battery cell 20, thereby reducing the cost, failure rate and maintenance difficulty of the testing equipment.

[0043] In some embodiments of this utility model, reference is made to Figure 6As shown, in the depth direction perpendicular to the cell slot 13, the positive cell contact 21 and the negative cell contact 31 are located on opposite sides of the corresponding cell slot 13.

[0044] Specifically, the depth direction of the battery cell slot 13 can be... Figure 6 The vertical direction, perpendicular to the depth direction of the cell slot 13, can be... Figure 6 In the left-right direction, the positive electrode contact 21 and the negative electrode contact 31 are located on opposite sides of the corresponding cell slot 13, which can increase the spacing between the positive electrode contact 21 and the negative electrode contact 31, increase the creepage distance between the positive electrode contact 21 and the negative electrode contact 31, reduce the risk of short circuit between the positive electrode contact 21 and the negative electrode contact 31, and ensure the safety of the formation capacity tray 10.

[0045] In some embodiments of this utility model, reference is made to Figure 6 As shown, both the positive electrode cell contact 21 and the negative electrode cell contact 31 extend along the depth direction of the cell slot 13.

[0046] Specifically, both the positive electrode contact 21 and the negative electrode contact 31 extend in the vertical direction to increase the contact area between the positive electrode contact 21 and the positive electrode tab 201, and the contact area between the negative electrode contact 31 and the negative electrode tab 202. This helps to improve the conduction efficiency between the battery cell 20 and the positive and negative conductive busbars, and reduces the heat generation of the positive electrode contact 21 and the negative electrode contact 31.

[0047] It should be noted that, in the left-right direction, the positive electrode contact 21 can abut against the left side wall of the cell slot 13, and the negative electrode contact 31 can abut against the right side wall of the cell slot 13. When the cell 20 is installed in the cell slot 13, the positive electrode tab 201 at the left end of the cell 20 can abut against the positive electrode contact 21, and the negative electrode tab 202 at the right end of the cell 20 can abut against the negative electrode contact 31. Due to the support of the left side wall of the cell slot 13 for the positive electrode contact 21 and the right side wall for the negative electrode contact 31, the positive electrode contact 21 and the positive electrode tab 201 can form a stable contact, and the negative electrode contact 31 and the negative electrode tab 202 can form a stable contact, so as to avoid incomplete connection.

[0048] In some embodiments of this utility model, reference is made to Figure 4 , Figure 6 and Figure 7As shown, the formation and capacity tray 10 also includes multiple gaskets 4, each corresponding to a multiple cell slot 13. The gaskets 4 are laid on the bottom wall of the corresponding cell slot 13. Each gasket 4 includes a positive conductive sheet 41, a negative conductive sheet 42, and an insulating sheet 43. The positive conductive sheet 41 is in contact with the positive cell contact 21 and is conductive. The negative conductive sheet 42 is in contact with the negative cell contact 31 and is conductive. The insulating sheet 43 is connected between the positive conductive sheet 41 and the negative conductive sheet 42.

[0049] Specifically, the positive electrode conductive sheet 41 can make contact with the positive electrode cell contact 21 and the positive electrode tab 201 respectively, and the positive electrode conductive sheet 41 can increase the contact area between the positive electrode cell contact 21 and the positive electrode tab 201 at the bottom of the cell slot 13. The negative electrode conductive sheet 42 can make contact with the negative electrode cell contact 31 and the negative electrode tab 202 respectively, and the negative electrode conductive sheet 42 can increase the contact area between the negative electrode cell contact 31 and the negative electrode tab 202 at the bottom of the cell slot 13. This helps to improve the conduction efficiency between the cell 20 and the positive electrode and the negative electrode, and reduce the heat generation of the positive electrode cell contact 21 and the negative electrode cell contact 31.

[0050] The insulating sheet 43 is connected between the positive conductive sheet 41 and the negative conductive sheet 42. The insulating sheet 43 can support the battery cell body 203 and reduce the risk of leakage of the battery cell body 203. At the same time, the insulating sheet 43 connects the positive conductive sheet 41 and the negative conductive sheet 42 into one piece, which not only ensures the electrical insulation between the positive conductive sheet 41 and the negative conductive sheet 42, but also makes the gasket 4 a single piece, so that the gasket 4 can be installed into the battery cell slot 13.

[0051] In some embodiments of this utility model, reference is made to Figures 2-9 As shown, the cell filling tray 10 also includes a snap-fit ​​cover 5, which is detachably or movably connected to the carrier tray 1, and the snap-fit ​​cover 5 is adapted to cover the opening of each cell slot 13.

[0052] In some embodiments, the snap-fit ​​cover 5 can be detachably connected to the carrier tray 1. When the snap-fit ​​cover 5 is removed from the carrier tray 1, the cell slots 13 on the carrier tray 1 are exposed to facilitate the installation or removal of the cell 20. When the snap-fit ​​cover 5 is installed on the carrier tray 1, the snap-fit ​​cover 5 is adapted to cover the opening of each cell slot 13. The snap-fit ​​cover 5 can press against the cell 20, thereby pressing the cell 20 into the cell slot 13 to prevent the cell 20 from being improperly installed. The snap-fit ​​cover 5 can also prevent the cell 20 from coming out of the cell slot 13.

[0053] In other embodiments, the snap-fit ​​cover 5 can be movably connected to the carrier tray 1. For example, the snap-fit ​​cover 5 can be slidably connected or hinged to the carrier tray 1. When the snap-fit ​​cover 5 moves to avoid the slot of the cell slot 13, the cell slot 13 on the carrier tray 1 can be exposed to facilitate the installation or removal of the cell 20. When the snap-fit ​​cover 5 moves to cover the slot of the cell slot 13, the snap-fit ​​cover 5 can press against the cell 20, thereby pressing the cell 20 into the cell slot 13 to avoid the cell 20 not being installed properly. The snap-fit ​​cover 5 can also prevent the cell 20 from coming out of the cell slot 13.

[0054] In some embodiments of this utility model, reference is made to Figures 2-9 As shown, the snap-fit ​​cover 5 has a plurality of positive electrode blocks 51 and a plurality of negative electrode blocks 52 corresponding to a plurality of battery cell slots 13. In the depth direction of the battery cell slots 13, at least a portion of the positive electrode block 51 is located in the corresponding battery cell slot 13 and is directly opposite to the positive electrode conductive sheet 41, and at least a portion of the negative electrode block 52 is located in the corresponding battery cell slot 13 and is directly opposite to the negative electrode conductive sheet 42.

[0055] Specifically, when the cover 5 is pressed to seal the opening of the cell slot 13, the positive electrode block 51 can press down against the positive electrode tab 201 inside the cell slot 13, so that the positive electrode tab 201 presses against the positive conductive sheet 41 of the pad 4, thereby avoiding a loose connection between the positive electrode tab 201 and the positive conductive sheet 41. The negative electrode block 52 can press down against the negative electrode tab 202 inside the cell slot 13, so that the negative electrode tab 202 presses against the negative conductive sheet 42 of the pad 4, thereby avoiding a loose connection between the negative electrode tab 202 and the negative conductive sheet 42.

[0056] In some embodiments of this utility model, reference is made to Figure 6 As shown, the positive electrode block 51 is a conductor and is in contact with the positive electrode cell contact 21, and the negative electrode block 52 is a conductor and is in contact with the negative electrode cell contact 31.

[0057] Specifically, the positive electrode block 51 can make contact with the positive electrode cell contact 21 and the positive electrode tab 201 respectively, and the positive electrode block 51 can increase the contact area between the positive electrode cell contact 21 and the positive electrode tab 201 at the top of the cell slot 13. The negative electrode block 52 can make contact with the negative electrode cell contact 31 and the negative electrode tab 202 respectively, and the negative electrode block 52 can increase the contact area between the negative electrode cell contact 31 and the negative electrode tab 202 at the top of the cell slot 13. This helps to improve the conduction efficiency between the cell 20 and the positive electrode busbar and the negative electrode busbar, and reduce the heat generation of the positive electrode cell contact 21 and the negative electrode cell contact 31.

[0058] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5As shown, the carrying tray 1 also has a cover limiting groove 14, which is located on one side of the slot of the cell slot 13 and communicates with each cell slot 13. At least a portion of the cover 5 is located in the cover limiting groove 14.

[0059] Specifically, the length and width of the cap limiting groove 14 can be adapted to the length and width of the snap cap 5. The snap cap 5 can be partially or completely located in the cap limiting groove 14. The cap limiting groove 14 improves the stability of the connection between the snap cap 5 and the carrying tray 1, and can also be used to provide guidance and positioning functions for the installation of the snap cap 5.

[0060] In some embodiments of this utility model, reference is made to Figure 4 As shown, the snap-fit ​​cover 5 is a rectangular cover, and the snap-fit ​​cover limiting groove 14 is a rectangular groove to avoid incorrect installation orientation of the snap-fit ​​cover 5 when it is installed on the support tray 1, and to ensure that the positive electrode pressure block 51 and the negative electrode pressure block 52 on the snap-fit ​​cover 5 correspond to the cell slot 13, thus realizing the foolproof installation design of the snap-fit ​​cover 5.

[0061] In some embodiments of this utility model, at least one of the snap-on cover 5 and the carrier tray 1 is made of transparent material to facilitate observation of whether the battery cell 20 is loosely connected or abnormal.

[0062] In some embodiments of this utility model (not shown in the figures), the carrying tray 1 is provided with a latch, which selectively locks into the snap-on cover 5.

[0063] Specifically, when the latch and the pressure cover 5 are locked in place, the pressure cover 5 maintains the position of the opening of the battery cell slot 13, thereby preventing the pressure cover 5 from shifting or separating from the support tray 1, ensuring the stability of the battery cell 20 and preventing the battery cell 20 from falling out of the battery cell slot 13. When the latch and the pressure cover 5 are released from the locking engagement, the pressure cover 5 can move or separate relative to the support tray 1, so as to facilitate the installation of the battery cell 20 into the battery cell slot 13 or the removal of the battery cell 20 from the battery cell slot 13. Optionally, the latch can be a mechanical latch or a magnetic latch.

[0064] In some embodiments of this utility model, reference is made to Figure 3 As shown, the support tray 1 is an injection molded part, and multiple reinforcing ribs 15 are provided on the side of the support tray 1 away from the cell slot 13.

[0065] Specifically, the support tray 1 can be injection molded to facilitate its manufacturing and reduce its manufacturing cost. The support tray 1 has multiple reinforcing ribs 15 on the side opposite to the cell slot 13. The reinforcing ribs 15 can be convex rib structures. The reinforcing ribs 15 can improve the structural strength of the support tray 1 and reduce the risk of deformation of the support tray 1.

[0066] Reference Figure 3As shown, the reinforcing rib 15 can be a long strip of raised rib structure, and some reinforcing ribs 15 intersect to form a grid structure to further enhance the structural strength of the load-bearing tray 1.
