Abstract
The utility model provides a connecting structure of battery modules. The connecting structure comprises the battery modules each consisting of a plurality of battery cells, wherein the electrodes of the battery cells are connected through electrode plates fixedly arranged at the two ends of each battery module; every two battery modules are connected through a collector plate; the collector plates are fixedly arranged on the upper end surfaces of the electrode plates. The purpose of simply and quickly connecting the battery cells in parallel or in series is achieved through the welding of the electrode plates, the battery modules are connected through the collector plates to form a battery pack, the operation is easy, and the industrialization production can be realized.
Description
Technical field
The utility model relates to technical field of lithium batteries, is specifically related to a kind of syndeton of battery modules.
Background technology
Because lithium battery environmental pollution is little, noiselessness, energy advantages of higher, be now widely used on new-energy automobile and drive automobile to advance as its power source.Power set as electric automobile are in series by a plurality of battery modules, and its each battery modules is got up to form by a plurality of cell group series and parallels.And for the series and parallel of cell, traditional connected mode generally has two kinds: a kind of is to use firm cell is coupled together, and has increased its contact resistance, thereby can improve the thermal power that battery pack consumes when work; Another kind of mode is to use nickel sheet that battery is linked together by welding manner, and its shortcoming is that complex operation, installation cost are large, and will realizing a large amount of cells, to carry out actual series and parallel not easy to operate while getting up.
Utility model content
The purpose of this utility model is just to provide a kind of syndeton of battery modules, reaches object simple to operate, easy suitability for industrialized production.
In order to reach above-mentioned effect, the utility model provides a kind of syndeton of battery modules, comprises the battery modules consisting of a plurality of cells, and the two ends of described battery modules connect the electrode of each cell by the electrode slice setting firmly on it; Between battery modules, by collector plate, connect between two, described collector plate is fixedly arranged on electrode slice upper surface.
Further, described electrode slice is welded on the both positive and negative polarity of each cell in battery modules, and described collector plate is welded on electrode slice upper surface, and the position with respect to each cell electrode in collector plate is provided with hole.
Further, described electrode slice is flake aluminum or thin aluminium nickel composite band, and its thickness is 0.1-1mm; Described collector plate is aluminium flake.
According to application target and requirement, by form a battery modules some cell by half positive pole upward, second half negative pole arranges upward, then electrode slice is placed on it, lower end, then use resistance welded or ultra-sonic welded that the positive and negative electrode of electrode slice and each cell is welded.This just by same electrode towards cell be together in parallel, and then the two parts that are together in parallel are together in series and have formed a jumbo battery modules.Finally as required several battery modules are arranged in together; aluminium matter collector plate in the welding of the upper surface of electrode slice; battery modules is together in series and forms jumbo working battery group; collector plate is also as the large power, electrically circulation road of working battery group; thereby improved the operating power of battery pack, also protected the use safety of battery pack simultaneously.
The syndeton of battery modules of the present utility model has simple in structure, consistent, has realized structure module design, first by electrode slice, a plurality of cells is formed to battery modules, monomer whose battery also, serial operation is simple and service speed is fast; And strengthened the structure of whole battery modules; Again a plurality of battery modules are connected to form to battery pack by collector plate, easy to operate and can realize suitability for industrialized production.

In figure: 1-cell, 2-electrode slice, 3-collector plate, 4-hole, 5-battery modules, 6-battery pack.
Embodiment
As shown in Figure 1, 2, 3, a kind of syndeton of battery modules, comprises the battery modules consisting of a plurality of cells 1, is undertaken the electrode of each cell 1 to connect after parallel connection by the electrode slice 2 setting firmly thereon in the two ends of described battery modules again; Between battery modules, by collector plate 3, connect between two, described collector plate 3 is welded in electrode slice 2 upper surfaces, and its position with respect to each cell electrode is provided with hole 4.
During operation, first electrode slice 2 is welded on the positive and negative electrode of each cell in battery modules, by cell also, be together in series; Again collector plate 3 is welded on to electrode slice 2 upper surfaces, a plurality of battery modules are connected into a jumbo working battery group.
Further, the material of above-mentioned electrode slice 2 is flake aluminum or thin aluminium nickel composite band, and its thickness is 0.1-1mm; The material of described collector plate 3 is aluminium flake.
As shown in Figure 4, by nine battery modules 5, be groined type and arrange, by collector plate, connect and form a jumbo battery pack 6.
Above embodiment is not limited only to protection range of the present utility model, all based on basic thought of the present utility model, modify or change all belong to protection range of the present utility model.
