Abstract

The present invention relates to a lid for a battery module, in particular in an electric vehicle, comprising a cover section for pole-side attachment of the lid to the battery module, and tabs which are provided at opposite ends of the cover section, are arranged inclined relative to the cover section and, in a state in which the lid is installed on the battery module, extend from the cover section in a direction pointing away from the battery module.

First claim

1 : A lid for a battery module, comprising a cover section for pole-side attachment of the lid to the battery module, and tabs which are provided at opposite ends of the cover section, arranged inclined relative to the cover section and, in a state in which the lid is configured to be installed on the battery module, extend from the cover section in a direction pointing away from the battery module.

2 : The lid according to claim 1 , wherein the tabs each form a flange, in particular for attaching the cover to a carrier structure of at least one of: a battery and a further cover of a battery module.

3 : The lid according to claim 1 , wherein the tabs have at least one connecting element which is complementary to a mounting tool, wherein the at least one connecting element is configured to mechanically connect the lid to the mounting tool in a detachable fashion.

4 : The lid according to claim 3 , wherein the at least one connecting element is a through-opening which passes through the tabs.

5 : The lid according to claim 1 , wherein the tabs extend along a longitudinal side of at least one of: the lid and the battery module.

6 : The lid according to claim 1 , wherein in the state in which the lid is mounted on the battery module the tabs project beyond the battery module along a transverse direction of at least one of: the lid and the battery module on at least one side.

7 : The lid according to claim 1 , wherein in the state in which it is mounted on the battery module, a width of the lid along a transverse direction (Y) of at least one of: the lid and the battery module is greater than or equal to a width of the battery module.

8 : The lid according to claim 1 , wherein the tabs are inclined substantially about 90° relative to the cover section.

9 : The lid according to claim 1 , wherein said lid has a U-shaped profile in cross section, wherein the cover section forms a web, and the tabs adjoining the web form limbs of the U-shaped profile, and wherein in the state in which the lid is mounted on the battery module the outer side of the web of the U-shaped profile at least one of: bears against the battery module and lies opposite the battery module.

10 : The lid according to claim 1 , wherein the cover section comprises at least one positively engaging element which is complementary to a structure of the battery module, in particular in the form of a cutout, for at least one of: positioning the lid relative to the battery module and connecting the lid to the battery module in a positively engaging fashion.

11 : The lid according to claim 1 , wherein the cover section has two cutouts for poles of the battery module, wherein in the mounted state on the battery module the poles are at least one of: arranged in the cutouts and project through the cutouts and are, in particular, in positively engagement therewith.

12 : A battery module arrangement, in particular for an electric vehicle, having at least one battery module and one lid, wherein the lid is configured to be attached on a pole side to the battery module.

13 : A battery, comprising at least two battery module arrangements, wherein at least one of the at least two battery module arrangements comprise at least one battery module and one lid, wherein the lid is configured to be attached on a pole side to the battery module, wherein the at least two battery module arrangements are connected to one another via tabs, lying opposite one another, of the lids of the battery module arrangements.

14 : The battery according to claim 13 , wherein the tabs, lying opposite one another, of the respective lids bear one on the other and are connected to one another in at least one of: a frictionally engaging and a materially joined fashion, in particular by means of semi-tubular punch rivets.

15 : The lid according to claim 4 , wherein the through-opening is at least one of: a drilled through-hole, an elongate hole, a punched-out portion, and a polygonally formed opening.

16 : The lid according to claim 5 , wherein the tabs extend along at least 50% of the longitudinal side of at least one of: the lid and the battery module.

17 : The lid according to claim 5 , wherein the tabs extend along 90% of the longitudinal side of at least one of: the lid and the battery module.

18 : The lid according to claim 6 , wherein the tabs have a flange for connecting to at least one of: a battery component and a further flange of an adjacent battery module, wherein the flange is formed bent outward with respect to the plane of the tab.

19 : The lid according to claim 1 , wherein the battery module is configured to be used in an electric vehicle.

20 : The battery according to claim 13 , wherein the battery is configured to be used in an electric vehicle.
