Abstract
The utility model discloses a power battery pack boundary busbar, which comprises a strip-shaped copper plate. A long edge of the copper plate is provided with a plurality of nickel straps, and the copper plate is further provided with a bolt. Carrying capacity and assembly efficiency of the power battery pack boundary busbar are increased.
Description
Technical field
The utility model relates to the battery technology field, especially relates to a kind of power battery pack border bus-bar.
Background technology
Because advantages such as lithium ion battery have the voltage height, capacity is big, volume is little, light weight, and operating temperature range is wide, the lithium ion battery group has been widely used in every field, especially is applied to the motor vehicle field.At present electric vehicle battery string and number are more, and in order to guarantee the safety in the battery pack process of assembling and to improve production technology, and battery is maintainable after sale, and battery system is taked modularized design, and the battery strings of different numbers and together forms a module.Connect between the battery between the module by relatively thinner bus-bar connection, single mode group border has certain requirement because need afflux to bus-bar thickness.At present, also good without comparison solution countermeasure.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of power battery pack border bus-bar, improves the current capacity and the packaging efficiency of power battery pack border bus-bar.
For achieving the above object, the utility model by the following technical solutions: a kind of power battery pack of the present utility model border bus-bar, comprise a bar shaped copper coin, the long limit of copper coin is provided with some nickel straps, also is provided with double-screw bolt on the copper coin.
Further, adopt welding manner to interconnect between described copper coin and the nickel strap; Adopt welding or riveted joint mode to interconnect between double-screw bolt and the copper coin.
The beneficial effects of the utility model are: compared with prior art, as the material that connects electric core, be the material of concentrating electric current with copper coin with nickel strap.Nickel strap and copper coin adopt the technology of Laser Welding to weld together, and electric core pole plate and nickel strap are connected together by Resistance Welding.The single battery electric current focuses on the copper coin by nickel strap, focuses on an end by copper coin again, links to each other with next power brick by bolt column.Because structural design is reasonable, has significantly improved assembling efficiency, improved the manufacturability in the assembling.Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can realize and obtain by specifically noted structure in following specification and the accompanying drawing.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in drawings, power battery pack of the present utility model border bus-bar comprises a bar shaped copper coin 1, and the long limit of copper coin 1 is provided with some nickel straps 3, is 6 nickel straps 3 in the present embodiment, also is provided with double-screw bolt 2 on the copper coin 1; During use, electric core pole plate and nickel strap 3 are connected together by Resistance Welding, and nickel strap 3 thickness, afflux can be determined according to actual conditions with copper coin 1 thickness; Adopt the technology of Laser Welding to weld together between described copper coin 1 and the nickel strap 3; Adopt welding or riveted joint mode to interconnect between double-screw bolt 2 and the copper coin 3.During work, as the material that connects electric core, be the material of concentrating electric current with copper coin 1 with nickel strap 3.The single battery electric current focuses on the copper coin 1 by nickel strap 3, focuses on an end by copper coin 1 again, links to each other with next power brick by bolt column 2.Because structural design is reasonable, has significantly improved assembling efficiency, improved the manufacturability in the assembling.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
