Abstract
The utility model provides low-cost lithium battery pack connecting components, comprising single batteries, wherein electrode lugs are welded at electrodes of the single batteries, each electrode lug comprises a lug part and a handle part, each lug part and the corresponding handle part are connected through an arched connecting part, the bottom end face of each lug part is welded on the corresponding electrode of the corresponding single battery, and the upper end faces of the handle parts are welded on a collector plate for connecting the single batteries in series and parallel for forming a lithium battery pack. The electrode lugs are made of aluminum and nickel composite materials, and the collector plate is made of aluminum, so that reliable connection between the aluminum collector plate and the nickel electrodes of the single batteries is realized, the production cost of the connecting component is reduced, and the performance of the lithium battery pack is ensured.
Description
Technical field
The utility model relates to technical field of lithium batteries, is specifically related to one lithium battery group link cheaply.
Background technology
Because lithium battery environmental pollution is little, noiselessness, energy advantages of higher, be now widely used on new-energy automobile as its power source.Its power source gets up to form jumbo battery pack by multiple battery cell series and parallels.In the series parallel structure of battery pack, mainly by link, connect with electric current and collect.
Due to normally nickel or the steel nickel plating of electrode surface material of battery cell, so will realize the connection in series-parallel between each battery cell in battery pack, the material of its link will adopt nickel material, copper material or copper nickel plating material conventionally, then by resistance welding technology, by between them, connects.The cost of nickel material, copper material or copper nickel plating material is higher, be generally aluminum price 3-10 doubly.If link is directly adopted to aluminum, can affect the overall performance of firm welding and lithium battery group.
Utility model content
The purpose of this utility model is just to provide one lithium battery group link cheaply, reaches that cost is low, firm welding, object that performance is good.
In order to reach above-mentioned effect, the utility model provides one lithium battery group link cheaply, comprise battery cell, the electrode place of described battery cell is welded with electrode ear, described electrode ear comprises ear, shank, between described ear, shank, by arc connecting portion, connected, the bottom face of described ear is welded on the electrode of battery cell, and the upper surface of shank is welded in collector plate battery cell connection in series-parallel is formed to lithium battery group.
Further, described ear is nickel sheet; Described connecting portion and shank are double-decker, and its lower floor is nickel sheet, and upper strata is aluminium flake; Described collector plate is aluminium flake.
Further, in described collector plate, with respect to the position of the ear on electrode ear and connecting portion, offer porose.
Electrode ear is by the synthetic one side of hot melt compression technology, to be that aluminium one side is that the composite material of nickel is made by one deck aluminium flake, one deck nickel sheet, after its addition moulding, with etching, remove aluminium technique the upper strata aluminium flake of the ear being connected with battery cell electrode in electrode ear is removed.First with resistance welding technology, the shank aluminium flake in electrode ear is welded in the collector plate of aluminium material, then the ear in electrode ear is welded on the electrode of battery cell.Remaining nickel sheet only after the upper strata aluminium flake of ear is removed, because nickel sheet and battery electrode surfacing are commaterial, its welding characteristic is consistent, thereby more reliable and more stable between electrode ear and battery cell while making resistance welded; Realize the reliable connection of aluminium collector plate to battery cell nickel electrode, thereby guaranteed the performance of batteries of electric automobile group.
So the beneficial effects of the utility model have:
1, because electrode ear middle interconnecting piece is arc, make itself and collector plate form shockproof flexibly connecting.
2, the utility model is used the material of aluminium as collector plate, thereby has greatly reduced the production cost of link;
3, the utility model has been realized mature and stable reliable processing process that can suitability for industrialized production, can realize industrialized mass, reduces production costs.
