One surface of the panel 1 is provided with the positive electrode connecting piece 2 and the negative electrode connecting piece 3, and the other surface is provided with the external positive electrode 4 and the external negative electrode 5. The positive electrode connecting piece 2 and the external positive electrode 4 are electrically connected through the panel 1, and the negative electrode connecting piece 3 and the external negative electrode 5 are electrically connected through the panel 1. The positive electrode connecting piece 2 connects to the positive electrode wire of the battery assembly, and the negative electrode connecting piece 3 connects to the negative electrode wire of the battery assembly.

In this embodiment, the positive and negative electrode connecting pieces are fixed in the panel of the battery box cover, making the connection performance of the battery assembly stable, safe, reliable, convenient, and practical, with standardized, neat, and aesthetically pleasing wiring.

[0024] As an optional solution, in this embodiment, the panel 1 is provided with two positioning grooves 7, and the positive electrode connecting piece 2 and the negative electrode connecting piece 3 are respectively engaged in one positioning groove 7. In this embodiment, the positioning grooves 7 are used to position the two electrode connecting pieces, which helps to use automated welding equipment for welding, realize standardized operations, and improve the stability and aesthetics of the connection. Among them, the negative electrode riveting point is located at the center of the panel 1, and the positive electrode riveting point is located in the non-central area of ​​the panel 1. The specific positions can be changed according to design requirements.

[0025] As an optional solution, in this embodiment, panel 1 is used to seal the upper opening of the battery box. Panel 1 is provided with several limiting posts 6, which are used to abut against the upper surface of the battery assembly, so that the battery block can be stably placed in the battery box without shaking up and down.

[0026] As an optional solution, in this embodiment, the number and position of the limiting posts 6 are matched one-to-one with the battery blocks in the battery assembly. The limiting posts 6 are located on the surfaces where the positive electrode connecting piece 2 and the negative electrode connecting piece 3 are located. One limiting post 6 is used to match one battery block, thus avoiding material waste.

[0027] As an optional solution, in this embodiment, the positive electrode connecting piece 2 is riveted to the external positive electrode 4 by rivets 8, and the negative electrode connecting piece 3 is riveted to the external negative electrode 5 by rivets 8 for positioning, fixing, and conductive connection. This facilitates subsequent welding of the electrode connecting pieces and the electrodes of the battery module using automated welding equipment. The rivets 8 are made of conductive material. The panel 1 has two positioning through holes as riveting points for the positive and negative electrodes.

[0028] As an optional solution, in this embodiment, both the positive electrode connecting piece 2 and the negative electrode connecting piece 3 include an integrally formed annular connecting piece and a rectangular connecting piece. The annular connecting piece is connected to the external electrode, and the rectangular connecting piece is connected to the electrode wire of the battery assembly.

[0029] As an optional solution, in this embodiment, the length of the negative electrode connecting piece 3 is greater than the length of the positive electrode connecting piece 2. Both the positive electrode connecting piece 2 and the negative electrode connecting piece 3 protrude from the edge of the panel 1, so as to avoid the area of ​​the panel 1 during subsequent welding. The width of the positive electrode connecting piece 2 and the negative electrode connecting piece 3 is 2mm-5mm and the thickness is 0.5mm-2mm.

[0030] As an optional solution, in this embodiment, the thickness of panel 1 is greater than the thickness of positive electrode connecting piece 2 and negative electrode connecting piece 3 by 2mm-5mm, providing good flexibility and ease of bending, which facilitates bending during packaging. Panel 1 is made of insulating material, which is waterproof and moisture-proof.

[0032] As an optional solution, in this embodiment, the materials of the positive electrode connecting piece 2, the negative electrode connecting piece 3, the external positive electrode 4, and the external negative electrode 5 include any one of conductive metal and conductive metal alloy. In this embodiment, hand-tearable steel and copper are preferred, as they are sturdy, durable, and have good conductivity.

[0033] In this embodiment, during the assembly of the electrode panel 1 for the combined battery assembly, the electrode connecting pieces are first manually placed in their corresponding positions according to the orientation of the positioning grooves 7. The circular connecting pieces are then inserted into the circular holes of the panel 1 using rivets 8. On the other side of the panel 1, the spring electrodes are correspondingly mounted on the rivets 8. The connecting pieces are then riveted together with the positive and negative spring electrodes of the panel 1. The riveted positive and negative connecting pieces are then automatically spot-welded to the corresponding positive and negative terminals on the battery assembly using spot welding equipment. Because the panel 1 has positioning grooves 7, no manual support is required during automatic welding; spot welding can be performed directly, saving labor. This embodiment uses automatic spot welding to fix the positive and negative connecting pieces to the corresponding positive and negative batteries, cleverly securing them to the head panel of the first battery pack. The connection performance is stable, safe, reliable, convenient, practical, and aesthetically pleasing, with excellent performance.
