2. The battery module according to claim 1 , characterized in that the device for the coiling of a current-carrying or data-conducting cable comprises at least two projections ( 24 ) which project from the surface of the battery module cover ( 14 ) in a vertical direction in relation to said surface.

3. The battery module according to claim 1 , characterized in that the terminal ( 16 ) for a current-carrying or data-conducting cable ( 26 ) and the device for the coiling of a current-carrying or data-conducting cable are arranged in a recess ( 18 ) in the battery module cover ( 14 ).

4. The battery module according to claim 1 , characterized in that at least three cable guides ( 20 d - 20 f ) are provided for the routing of a data-conducting or current-carrying cable, which is connected to the terminal ( 16 ) for the current-carrying or data-conducting contacting of the battery module ( 10 ), to a further battery module or data receiver, wherein each of the cable guides ( 20 d - 20 f ) has a cable guide length which originates at the terminal ( 16 ) for the current-carrying or data-conducting contacting of the battery module ( 10 ) and terminates at an outer periphery of the battery module housing ( 14 ), wherein the sum of a respective first cable guide length of a first cable guide ( 20 d ) and a second cable guide length of a second cable guide ( 20 e ) is exactly equal to the sum of the first cable guide length of the first cable guide ( 20 d ) and a third cable guide length of a third cable guide ( 20 f ).

5. The battery module according to claim 1 , comprising at least two terminals ( 16 ) for a data-conducting or current-carrying cable ( 26 ) and at least four cable guides for the routing of a data-conducting or current-carrying cable ( 26 ), which is connected to the terminals ( 16 ), to a further battery module or data receiver, wherein the cable guides terminate at outer edges of the battery module housing, each of the cable guides having a cable guide length which originates at one of the terminals and terminates at an outer edge of the battery module housing, and in that the sum of a cable guide length of a first cable guide ( 20 d ) originating at a first terminal ( 16 ) and terminating at a first outer edge of the battery module housing and the cable guide length of a second cable guide originating at a second terminal and likewise terminating at the first outer edge of the battery module housing is equal to the sum of a cable guide length of a third cable guide ( 20 f ) originating at the first terminal ( 16 ) and terminating at an outer edge of the battery module housing which is arranged opposite the first outer edge, and a cable guide length of a fourth cable guide originating at the second connecting point and likewise terminating at the outer edge of the battery module housing which is arranged opposite the first outer edge.

6. The battery module according to claim 4 , characterized in that the calculated cable guide length respectively further incorporates length segments of a cable ( 26 ) which is to be routed, which are secured by the take-up of the cable ( 26 ) on the device for the coiling of the current-carrying or data-conducting cable ( 26 ) to form a cable coil of the current-carrying or data-conducting cable ( 26 ).

7. The battery module according to claim 4 , characterized in that the cable guides ( 20 d - 20 f ) are configured in the form of a cable duct.

8. The battery module according to claim 7 , characterized in that the cable duct is impressed into at least one outer surface of the battery module housing.

9. The battery module according to claim 4 , characterized in that at least a part of the cable guides ( 20 d - 20 f ), in the plane of the battery module cover ( 14 ), are respectively routed to an outer edge of the battery module cover ( 14 ).

10. A battery pack having at least three battery modules ( 10 ) according to claim 1 , characterized in that, in an adjoining arrangement of the battery modules ( 10 ), a cable ( 26 ) connecting a first terminal ( 16 ) of the first battery module ( 10 ) to a second terminal of a second battery module and routed in the cable guides ( 20 d - 20 f ) of the first and second battery modules is of equal length to a second data-conducting or current-carrying cable connecting the second terminal of the second battery module to a third terminal of the third battery module and routed in the cable guides of the second and third battery modules.

11. The battery pack having at least two battery modules ( 10 ) according to claim 1 , characterized in that, in an adjoining arrangement of the battery modules ( 10 ), a cable connecting a first terminal ( 16 ) of the first battery module ( 10 ) to a second terminal of a second battery module and routed in the cable guides ( 20 d - 20 f ) of the first and second battery modules ( 20 ) is of equal length to a second data-conducting or current-carrying cable ( 26 ) connecting the second terminal of the first battery module ( 10 ) to a first terminal of the second battery module and routed in the cable guides ( 20 d - 20 f ) of the first and second battery modules ( 10 ).
