    专利说明:

    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 relatively space, time and parts consuming.
    The object of the invention is to enable a space, time and part-saving connection of the cells.
    According to the invention this is achieved in that each individual module has a single cell frame for receiving at least one cell, and that at least two adjacent single cell frame are connected to each other by at least one positive connection.
    At least one single cell frame may be connected to an end plate by at least one positive connection, wherein preferably the positive connection is formed by a first positive locking element on the single cell frame and a reciprocal shaped second Formschiusselement on adjacent single cell frame or adjacent end plate
    The positive connection is preferably formed by a snap connection. This allows a particularly simple mating of the individual cell frames.
    It when at least two arranged on different longitudinal sides of the single frame form-fitting elements are arranged rotationally symmetrical with respect to a vertical axis of the single frame is particularly advantageous. This mutual arrangement of the positive locking elements makes it possible to obstruct every second single cell frame rotated by 180 °.
    Especially with integrated cooling channels, it is favorable if a seal is arranged between at least two adjacent individual cell frames.
    The adjacent single cell frames may eventually be interconnected by laser welding. It is particularly advantageous if the individual cell frames are formed by plastic injection molding. For laser welding, it is particularly advantageous if juxtaposed individual cell frames have different reflection or absorption behavior.
    The invention will be explained in more detail below with reference to FIG.
    FIG. 2 shows a detail of the energy store and FIG. 3 shows a single cell frame in an oblique view.
    The electrical energy storage device 1 includes at least one battery module 2 with a stack 3 of individual modules 5 not shown further cells, wherein an end plate 6 is arranged at each end of the stack. Each individual module 5 has a single cell frame 7 for receiving at least one battery cell.
    In order to easily connect the individual modules 5 to a battery module 2, 7 each Formschlussverbtndungen 8 are provided at least between two adjacent single cell frame, each positive connection 8 is formed in the embodiment as a snap connection. Each positive connection 8 consists of a first positive locking element 9 and a reciprocating positive locking element 10, wherein the first and second form-fitting part are formed interlocking. By mutual arrangement of the first and second positive locking element 9, 10, each second single cell frame 7 can be installed rotated by 180 ° about a vertical axis 7a. This optionally allows a parallel or serial connection of two cells within a single module 5.
