    The invention relates to an electrical energy store, in particular for motor vehicles, having at least one battery module with a plurality of individual modules each having at least one cell, wherein the individual modules are arranged between two outer end plates in a stack.
    It is known to connect the cells by screwing the printing plates together. However, this type of connection is very space, time and parts consuming.
    The object of the invention is to enable a space, time and part-saving connection of the cells.
    This is achieved by the fact that the battery module is looped around by at least one preferably formed by a steel band clamping band, wherein the cells are pressed together by the pressure plates.
    It is preferably provided that in the area of at least one end of each tension band is crimped overlapping with itself. Additionally or alternatively, it may also be provided that in the region of at least one end of each tension band is welded inextricably overlapping with itself.
    A particularly simple assembly results when the clamping band has at least one preferably preformed form-fitting region, wherein preferably at a first end of the clamping band arranged positive-locking region is positively connected to an end plate. Thus, only more tension needs to be applied to the second end prior to joining the two ends. Thereafter, the two ends can be connected permanently or non-detachably, for example, by welding and / or crimping.
    The invention will be explained in more detail below with reference to FIG.
    1 shows an electrical energy store according to the invention in an oblique view, FIG. 2 shows a detail of the energy store and FIG. 3 shows a tightening strap.
    The electrical energy storage device 1 includes at least one battery module 2 with a stack of 3 individual cells 5 having cells 4, wherein the individual modules 5 are pressed together by end plates 6. The bias is applied by a plurality of straps formed by steel straps 7, which wrap around the stacked individual modules 5 and the end plates 6. Each clamping band 7 is hooked to the end plate 6 of the battery module 2 with a preformed first end 8 forming a form-fit region 10 and subsequently wrapped around the battery module 2. Thereafter, the necessary biasing force is adjusted by train on the overlap of the steel strip to be welded - it must therefore be applied only at the second end 9 of the tension band 7, a tensile stress. By applying a defined tensile force F on the free second end 9 of the clamping band 7, the biasing force on the housing of the battery module 2 and thus also on the individual modules 5, is generated. Finally, the tension band 7 is crimped overlapping and / or welded. In Fig. 3, reference numeral 11 denotes welds of laser welding. By laser welding, the steel strip after application of the biasing force on a corresponding length inextricably connected annularly around the battery module 2.
    This type of connection allows significant savings in terms of parts, assembly time, space and cost. Furthermore, there is the advantage of a uniform pressure distribution. Warped plastic parts have no significant adverse effects on the pre-tensioning pressure.
