Description
Technical field
The invention belongs to battery apparatus field, be specifically related to a kind of pectination flexible connection structure for energy-storage battery.
Background technology
In the application of large-scale energy-storage system, cell need to be realized the capacity of energy-storage system and the expansion of power characteristic by parallel connection, to support the application of large electric current, therefore between the pole of cell, just need to connect the requirement that realizes cell parallel connection by copper bar.Because electrochemical reaction and the heating effect of cell in the time discharging and recharging can produce stress and deformation, the vibrations of cell application scenario also can cause stress and deformation, these stress and deformation cause between cell and pole stressed excessive, thereby damage battery, therefore need connection between each pole be resilient be that being connected between cell is flexible coupling, will avoid like this because the stress between cell and connection copper bar causes the damage of cell pole, thereby affect the reliability of system.
As depicted in figs. 1 and 2, the mode that at present cell is flexible coupling is to connect by the copper bar 2 with curved surface between the pole of adjacent two cells 1, the two ends of copper bar 2 are fixed on the pole of adjacent two cells 1 by hold-down nut 4 respectively, in the time that current ratio is larger, can adopt multilayer copper bar to increase the ability of overcurrent.Due to all very large (thickness of cell is greater than 4cm conventionally) of thickness of general cell, therefore the curved surface span to copper bar, the processing of thickness and adjacent two layers copper bar spacing is all than being easier to, be easy to realize, so generally this mode that is flexible coupling is enough to meet the needs of energy type energy-storage battery, but while being used in the powerful energy-storage system such as extended-range electric vehicle or hybrid electric vehicle, there is following problem: (1) is because needs are considered the problem of dispelling the heat, energy-storage system designs more and more thinlyyer, in order to improve space availability ratio, cell is all close together, cause like this span of copper bar curved surface sharply to be dwindled, (2) power of energy-storage system is increasing, electric current is increasing, although cell electric current in parallel is little, but all electric currents all can pass through each pole, copper bar must be supported large electric current, therefore the thickness of copper bar will be thickeied, copper bar thickness increases, the span of curved surface is dwindled again, causes the thickness of copper bar and the conflicting situation of the span of curved surface, and the difficulty of processing of copper bar increases, if adopt above-described traditional flexible connection structure, will cause shape strain and stress, the span of copper bar curved surface reduces as shown in Figure 3, affects the reliability of system.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of pectination flexible connection structure for energy-storage battery, by the copper bar of surfacing and the pectination flexible connection structure that connects and composes cell of bus-bar, without the contradiction between copper bar thickness and the curved surface span considered in the past, simple structure, length changes flexibly, has a good application prospect.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of pectination flexible connection structure for energy-storage battery, it is characterized in that: comprise several cells and be located at the bus-bar on cell, on the pole of each cell, be equipped with a copper bar arranging along cell Width, the surface of described copper bar is plane, one end of described copper bar is connected with pole, and the other end of described copper bar is connected with bus-bar.
Aforesaid a kind of pectination flexible connection structure for energy-storage battery, is characterized in that: described copper bar and bus-bar are one-body molded.
Aforesaid a kind of pectination flexible connection structure for energy-storage battery, is characterized in that: described copper bar is fixed and is connected by connector with bus-bar.
Aforesaid a kind of pectination flexible connection structure for energy-storage battery, is characterized in that: described connector is the compliant conductive braid over braid of metal wire braiding.
The invention has the beneficial effects as follows: a kind of pectination flexible connection structure for energy-storage battery provided by the invention, comprise several cells, on the pole of each cell, connecting separately one end of a copper bar, the other end of each copper bar is all connected with a bus-bar, by the pectination flexible connection structure that connects and composes cell of a bus-bar and several copper bars, simple in structure being easy to realized; Because the electric current of each road copper bar is little, reduce the width of the copper bar of each connecting post, thinner copper bar is with regard to flexible, the thickness of copper bar and width are determined by the demand of overcurrent, the Design of length of this pectination flexible connection structure is more flexible, in the time of situation larger as electrokinetic cell width, just can use flexibly; Each road copper bar and bus-bar couple together, and the total current handling capacity of bus-bar is all pectination branch electric current sums; And the surfacing of copper bar, without curved surface, does not need to consider the problem between curved surface span and copper bar thickness.Copper bar and bus-bar can be integrated, can be also by connector as the compliant conductive braid over braid of metal wire braiding etc. is fixed connection, manufacture and design simply, have a good application prospect.
