Abstract
The utility model provides a current-collecting sheet and a battery pack containing the current-collecting sheet; the current-collecting sheet comprises a current-collecting body and connecting pieces which are extended out from two left and right sides of the current-collecting body, wherein the current-collecting body of the current-collecting sheet is made of copper, and the connecting piece of the current-collecting sheet is made of nickel. The technical proposal provided by the utility model saves cost and improves the stability of a product compared with the prior art.
Description
Technical field
The utility model relates to a kind of electric device, especially relates to the electric device in the battery pack.
Background technology
Along with global energy is more and more in short supply, electric automobile has become one of project that various countries' auto industry gives priority to.And battery is the subject matter of restriction electric automobile development, the potential safety hazard of, battery pack low excessively comprising the energy storage density of battery and electrical stability etc.
Adopt series connection and mode in parallel to form jumbo motive-power battery group by monocell, the flow collection sheet that battery pack inside is used for being electrically connected between monocell has various structures, disclosed the brace that a kind of flow collection sheet comprises the extended a plurality of symmetries of the conductive body and the conductive body left and right sides among the Chinese patent ZL200510007271.0, brace is used for welding with monocell, and each flow collection sheet can be electrically connected two row's monocells.Be compared to chip battery pole plates and the flow collection sheet that can only be electrically connected single monocell, this flow collection sheet more can be saved cost.Mentioning flow collection sheet in this patent document can be that simple nickel sheet or upper and lower surface layer are that nickel sheet intermediate layer is constituted by copper sheet is folded mutually.
But, because monocell is assembled into motive-power battery, as when being used for electric automobile, can consume a lot of flow collection sheets that are electrically connected usefulness, and flow collection sheet will carry very large electric current, though the upper and lower surface layer that discloses among the patent ZL200510007271.0 is nickel sheet intermediate layer is that the folded mutually flow collection sheet of copper sheet is compared to that pure nickel flow collection sheet resistivity is low, cost reduces, be compared to the welding of fine copper flow collection sheet easily, weld strength is high.But on the flow collection sheet conductive body, also still use the nickel sheet, not only cause flow collection sheet resistance to increase, also wasted nickel material simultaneously.
The utility model content
The technical problems to be solved in the utility model is to provide to be used in a kind of battery pack, is applicable to that big electric current passes through, and can with the flow collection sheet of battery firm welding, and the battery pack that comprises this flow collection sheet.
The utility model provides a kind of flow collection sheet, and this flow collection sheet comprises bar shaped conductive body and the brace that stretches out from bar shaped conductive body both sides, and described bar shaped conductive body is a copper sheet, and brace is the nickel sheet.
The conductive body of flow collection sheet and brace are electrically connected closely.Brace can weld or be riveted on the bar shaped conductive body of flow collection sheet, also can guarantee that the close-connected connected mode of bar shaped conductive body and brace is connected the bar shaped conductive body with brace by other.
On the described brace one or more projection can be arranged.
Preferred described each brace only stretches out in a side of flow collection sheet bar shaped conductive body.
Further preferred described all braces alternately stretch out in flow collection sheet bar shaped conductive body both sides.
The flow collection sheet conductive body that adopts in the utility model is a copper, and resistivity is low, and cost is low, and brace is a nickel, welding easily, the weld strength height reduces cost, reduces the effect that battery pack resistance and monocell are connected firmly so power battery pack adopts this flow collection sheet to reach.
On the brace that adopts in the utility model projection is arranged, it is more fastening to be convenient to the welding of brace and monocell, prevents that brace from coming off from monocell.
Flow collection sheet alternately stretches out in the conductive body both sides, and the monocell that goes for battery pack is arranged structure more closely.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
As depicted in figs. 1 and 2, flow collection sheet 1 is made up of conductive body 2 and brace 3, brace 3 stretches out from the both sides of conductive body 2, and the connected mode of conductive body 2 and brace 3 can be welding, riveted joint, and perhaps other can guarantee the connected mode that conductive body 2 and brace 3 closely are electrically connected.Conductive body 2 is riveted joint with brace 3 in the present embodiment, and wherein conductive body 2 is a copper sheet, and brace 3 is the nickel sheet.As shown in Figure 3, on brace 3, be useful on and the more firm projection 4 of monocell 7 welding.
As Fig. 3, Fig. 4, shown in Figure 5, a plurality of parallel flow collection sheets 1 are connected with a positive conductive plate 5 or negative conductive plate 6, are used for drawing of battery pack positive pole or negative pole.
