[0002] The battery cell usually includes a core pack and a top cover assembly arranged on the core pack. The top cover assembly usually includes a pole, a mounting part for mounting the pole, etc. One end of the pole is used to connect to the pole ear on the core pack, and the other end is exposed outside the battery cell as a contact point when the battery cell is discharged.

[0003] Integrated busbar (CCS or IBB) is a highly integrated battery signal acquisition and management system. The existing CCS mainly consists of an insulating film, a signal acquisition component (FPC component or FFC component) and a conductive bus connection structure (aluminum bus). The FPC component includes an FPC board, a nickel sheet, an NTC resistor, etc. The conductive bus connection structure is usually a single formed aluminum connection sheet during processing.

[0004] In the existing energy storage pack, it is necessary to connect several battery cells in series with their welded battery cells through an integrated busbar. When welding the integrated busbar and the battery cells, the operation requirements for the staff are very high. During the production process, for those technicians who have just been exposed to battery cell welding, they are very unfamiliar and cannot directly perform actual welding on the physical battery cells and the integrated busbar, otherwise it is easy to cause damage to the battery cells and the integrated busbar. Therefore, an auxiliary tool that simulates the battery cell welding integrated busbar is needed for technicians to conduct operation drills. Utility Model Content

The following is a description of the embodiments of the present invention based on its overall structure.

[0027] See also Figure 1-4A simulated battery cell 14 welding integrated busbar auxiliary tool includes a support frame 1 and a limiting plate 2; the limiting plate 2 is covered on the support frame 1, and a plurality of mounting grooves 3 are opened on the top of the support frame 1; a plurality of welding openings 4 are opened on the limiting plate 2, and the plurality of welding openings 4 are arranged in two rows horizontally along the limiting plate 2, wherein one row of welding openings 4 is located at one end of the mounting groove 3, and the other row of welding openings 4 is located at the other end of the mounting groove 3, and the positions of the welding openings 4 in one row are staggered relative to the welding openings 4 in the other row, and each welding opening 4 is arranged across two adjacent mounting grooves 3.

[0028] In the above scheme, the battery cell 14 for simulated welding is installed on the installation groove 3, and the limiting plate 2 has an area larger than the area of ​​the top of the support frame 1. When the limiting plate 2 is covered, each welding opening 44 on each row of the limiting plate 2 spans one end of two adjacent installation grooves 3, and each welding opening 44 on the other row spans the other end of the other two adjacent installation grooves 3, such as Figure 1 As shown, taking three adjacent mounting slots 3 as an example, the first welding slot 4 of the first row of welding slots 45 is arranged across one end of the first mounting slot 7 and the second mounting slot 8, and the first welding slot 4 on the second row of welding slots 46 spans the second mounting slot 8 and the third mounting slot 9, and is located at the other end of the third mounting slot 9. In this way, the first row of welding slots 4 and the second row of welding slots 4 are staggered, and the battery cells 14 installed on the first mounting slot 7, the second mounting slot 8 and the third mounting slot 9 can be connected in series, and then the simulated integrated busbar is welded to the battery cells 14, and finally the battery cells in the three mounting slots 3 are connected in series. Similarly, the battery cells 14 in other mounting slots 3 are welded in this way.

[0029] like Figure 1 As shown, rectangular notches 10 are provided on both sides of the welding opening 4. The rectangular notch 10 is arranged at the center of the side of the welding opening 4, and the rectangular notch 10 and the welding opening 4 form a welding window of a cross-shaped structure, which is convenient for taking and placing the simulated integrated busbar across two adjacent mounting slots 3, that is, for welding the simulated integrated busbar to the simulated battery cell 14 installed on the mounting slot 3 for series welding.

[0030] like Figure 1 As shown, adjacent mounting grooves 3 are separated by partitions 11, and the partitions 11 are arranged directly below the rectangular notch 10. In order to make the integrated busbar better and symmetrically placed on two adjacent mounting grooves 3, two battery cells 14 are symmetrically welded at both ends of the integrated busbar, and the partitions 11 are arranged directly below the rectangular notch 10, and the partitions 11 are just at the center line position of the rectangular notch 10.

[0031] like Figure 1 As shown, the bottom of the support frame 1 is a frame-like structure. The bottom of the support frame 1 is a hollow frame-like structure, which reduces the weight of the support frame 1 and facilitates the handling of the support frame 1.

[0032] like Figure 1 , 4 As shown, both sides of the support frame 1 are provided with square holes 12. When carrying the support frame 1, the support frame 1 can be moved by hand through the square holes 12 on both sides, which is helpful to move the support frame 1 and saves effort.

[0033] like Figure 1 , 2 As shown, the number of welding ports 4 in two rows is equal. In this embodiment, the number of welding ports 4 in each row is 6, and other numbers of welding ports 4 can be selected in other embodiments. The battery cells 14 can be better connected in series in a complete and neat manner, and the entire structure is more stable.

[0034] In addition, reinforcing plates (not shown) are fixed at intervals inside the support frame 1. The reinforcing plates are arranged at the bottom of the support frame 1 to improve the stability of the entire support frame 1.

[0035] like Figure 2 As shown, the bottom of the limit plate 2 is provided with a slot 13 corresponding to the partition 11, and the limit plate 2 is plugged into the partition 11 through the slot 13. In order to cover the limit plate 2 on the top of the support frame 1, slots 13 corresponding to the number and size of the partitions 11 are provided, wherein the slots 13 can be arranged across the entire bottom of the limit plate 2, or can be arranged to have a width that is equal to the width of the partition 11. During installation, the battery cell 14 to be simulated for welding is first placed in the installation slot 3. At this time, the partition 11 partially protrudes from the upper surface of the simulated battery cell 14, and the protruding part of the partition 11 is snapped into the slot 13. During the process of simulated welding, the limit plate 2 slides, causing welding deviation.
