    The invention relates to an electrical energy store, in particular for motor vehicles, having at least one battery module with a plurality of arranged between two outer end plates in a stack of individual cells, preferably at least one single cell in one; Single module is arranged. +
    It is known to carry out the cooling and / or heating of a battery case with: a cooling medium. The disadvantage is that it coolant connections are required you take the cooling channels in the battery module relatively much space. The relatively large number of components also has a disadvantageous effect on the manufacturing costs.
    The object of the invention is to avoid these disadvantages and to enable optimal conditioning of the battery module with little effort.
    According to the invention this is achieved in that between at least two individual cells, preferably between two individual modules, a preferably flexible electrical heating element is arranged, wherein preferably the heating element is formed by a preferably flexible heating foil. Due to the flexible design, a contour adjustment is possible.
    The heating element may be a resistance heating element with heating wires.
    It is particularly advantageous that the heating element is at least partially surrounded by a cooling element and laser welded. The cooling element may be formed by a preferably made of sheet metal cooling plate. But it is also possible that the cooling plate is made of plastic.
    A particularly good cooling effect can be achieved if the cooling element is folded over a large area around the heating element and thus both sides of the • «· < »Ö *, · ί« • · * · »^ *« • «(* · * 4 · *« · ·
    Heating element encloses. Equally, however, a one-sided contacting of the cooling element with the heating element is possible.
    The cooling element may be glued to the heating element. Alternatively or additionally, the connection between the heating element and the cooling element can also take place by positive locking.
    The invention will be explained in more detail below with reference to FIG.
    FIG. 2 shows a stack of individual cells of this energy store in an oblique view, FIG. 3 shows the stack in a side view, FIG. 4 shows a heating and cooling element in an oblique view, FIG Heating and cooling element in a partially sectioned oblique view and Fig. 6, the heating and cooling element in a further oblique view.
    The electrical energy storage device 1 contains at least one battery module 2 with a stack 3 of individual modules 5 having individual cells 4a, 4b, an end plate 6 being arranged at each end of the stack. Each individual module 5 has a single cell frame 7, wherein in the exemplary embodiment each individual cell frame accommodates a cell pair 4 with a first and a second single cell 4a, 4b.
    Between two adjacent cells 4b and / or between two adjacent individual modules 5, a combined heating and cooling unit 8 with a heating element 9 and a cooling element 10 is arranged.
    The heating element is formed by a thin flexible heating foil 9a, which may comprise resistance wires 9b. The flexible shape makes it possible to adapt to different surfaces. The heating element 9a is enclosed by a cooling element 10 made of, for example, folded sheet metal and is laser-welded. Thus, the cooling element forms on both sides of the heating element, a cooling plate 10a, 10b, which rests flat against the Einzellzellen the battery module 2. The heating and cooling unit 8 can be clamped between two individual cell frames 7 and thus have maximum possible surface contact with the adjacent individual cells 4b. The heat removal from the cooling plates 10a, 10b can be done by air or liquid cooling. Optionally, Peltier elements can also be used for cooling.
    The connection between the cooling element 10 and heating element 9 can be done by gluing or by positive locking.
    Due to the extremely thin and flat design, the heating and cooling unit 8 requires only little space. The full-surface edition ensures a particularly good heat transfer.
