Background
Battery tabs refer to assemblies or components used to connect batteries, typically to establish electrical connection between batteries or between batteries and other electronic devices. They play an important role in battery technology, particularly in battery assembly and battery management systems.
The battery tabs are typically made of conductive materials, such as copper, because they are capable of efficiently transferring electrical current. The tabs may take different shapes and designs to accommodate particular types of batteries and connection requirements. They may have different ways of attachment, such as welding, screwing, crimping, etc., depending on the application and design.
During battery assembly, battery tabs are used to connect multiple battery cells together to create a battery pack. This helps to increase the voltage and capacity of the battery. In addition, the battery connection piece is also used for connecting the battery pack with a circuit of electronic equipment (such as a mobile phone, an electric vehicle, a solar energy system and the like) so as to supply power or charge.
In summary, battery tabs are a critical component in battery technology for establishing electrical connections between batteries and other electronic devices to ensure efficient current transfer and to achieve the desired transfer of electrical energy.
For connecting sheets with long connecting distance, for example, connecting sheets with the length of 1 meter or 2 meters or even longer, copper is generally adopted in the prior art, because copper is convenient to connect with a terminal of a battery, but when copper is adopted as the connecting sheet, the effect is not good because copper is higher in weight, for example, copper is used in places needing to be light in weight such as electric vehicles, airplanes and the like, and in addition, the price of copper is high, so that the manufacturing cost of the copper is high.

Detailed Description
The terminology used in the description of the embodiments of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application, as will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a battery connecting piece includes an aluminum row body portion 1, and an end portion of the aluminum row body portion 1 is provided with a lap joint portion 2.
As shown in fig. 3, the lap joint 2 includes a lap joint aluminum sheet 21 and a lap joint copper sheet 22, the lap joint copper sheet 22 is welded on the lap joint aluminum sheet 21 to form the lap joint 2, and the lap joint 2 is welded on the aluminum row body part 1 through the lap joint aluminum sheet 21.
Under the service environment of connecting sheets with longer length, compared with the whole connecting sheet adopting copper, the application has the advantages that: the aluminum row body part 1 is adopted as a main body, and the lap joint part 2 is arranged at the end part of the aluminum row body part, wherein the lap joint part 2 is formed by welding the lap joint aluminum sheet 21 and the lap joint copper sheet 22 together, so that the whole connecting sheet is lighter; in addition, the whole part of the application is aluminum, so the cost is lower than copper, and the cost of the application is low;
In addition, the application introduces the small lap joint part 2, because the application is applied to the field of connecting sheets with longer length and more than 1 meter, if the aluminum bar is directly welded on the copper terminal of the battery, the welding between copper and aluminum needs to be performed in a compound welding mode, and the compound welding needs to be provided with a pressing mechanism, so that the aluminum bar body part 1 is difficult to be directly welded on the copper terminal of the battery, while the application adopts the lap joint part 2, namely, the small lap joint copper sheet 22 is firstly welded on the lap joint aluminum sheet 21, and then the lap joint aluminum sheet 21 is welded on the aluminum bar body, and the lap joint part 2 is easy to clamp and position due to small volume area, thereby facilitating the welding in compound welding equipment, and after the welding, the aluminum bar body part 1 is welded on the copper terminal of the battery in a laser welding mode, and the welding of the battery is convenient due to no pressing of the laser welding.
In this embodiment, the welding mode of the lap copper sheet 22 and the lap aluminum sheet 21 is a composite welding.
In this embodiment, the welding mode of the overlap aluminum sheet 21 of the overlap portion 2 and the aluminum row body portion 1 is laser welding.
As shown in fig. 3, in the present embodiment, the welding portion of the lap portion 2 of the aluminum row body portion 1 is provided with a first positioning hole 11. The locating holes may be used to fix the position of the lap joint 2, ensuring that it does not move or shift during welding. This helps to maintain consistency and stability of the weld.
As shown in fig. 3, in the present embodiment, the overlapped aluminum sheet 21 is provided with a second positioning hole 211 corresponding to the first positioning hole 11. The second positioning holes 211 may help to fix the position of the aluminum tabs 21 to ensure that no unintended movement occurs during welding. This helps to maintain stability and consistency of the weld. The second positioning holes 211 may further ensure accurate alignment of the aluminum scrap sheet 21 and the aluminum busbar body part 1. Thus, the offset or error in the assembly process can be reduced, and the connection accuracy can be improved.
As shown in fig. 3, in the present embodiment, the lap copper sheet 22 includes a first welded portion 221, a bent portion 222, and a second welded portion 223, the bent portion 222 is bent and extended downward from one side of the first welded portion 221, and the second welded portion 223 is bent and extended to one side from the lower side of the bent portion 222. The presence of the bent portion 222 and the second welded portion 223 may increase the mechanical strength of the lap copper sheet 22 to make it more resistant to tensile and shear forces. This is important for applications requiring high strength connections. The presence of the bent portion 222 may alleviate thermal stress between the first and second welded portions 221 and 223 because the bent portion 222 serves as a buffer area, helping to disperse and absorb heat generated during welding.
As shown in fig. 3, in the present embodiment, a first welding void 224 is provided on the first welding portion 221. The clearance holes allow the welding material to penetrate more easily deep into the connection portion during the welding process. This helps to ensure adequate penetration of the weld, thereby improving the strength and reliability of the connection.
As shown in fig. 3, in this embodiment, the bending portion 222 is provided with a void-avoiding groove 225. The blind slots are typically used to make the connection at the bend 222, rather than being welded directly. This allows the bend 222 to have some bend tolerance so that the connection can accommodate some complex shapes or curves.
As shown in fig. 3, in the present embodiment, the second welding portion 223 is provided with a second welding void 226. The clearance holes can be used for removing potential bubbles or other bad substances, so that the purity of the welding area is ensured. This helps to reduce defects and holes in the weld.
