Abstract

A plate element for a battery module for receiving battery cells of the battery module includes a first plate element part and a second plate element part. The first plate element part is connected to the second plate element part. The first plate element part includes a first base body and a first organosheet arranged on the first base body. The second plate element part includes a second base body and a second organosheet arranged on the second base body.

First claim

The invention claimed is:

1. A battery module for arrangement in a battery housing, comprising:
a plurality of battery cells;
a first plate element part; and
a second plate element part arranged opposite the first plate element part,
wherein the first plate element part is connected to the second plate element part,
wherein the first plate element part comprises a first base body and a first organosheet arranged on the first base body,
wherein the second plate element part comprises a second base body and a second organosheet arranged on the second base body,
wherein the plurality of battery cells is accommodated between first plate element and the second plate element, and
wherein a first fixing element that is a fixed bearing is integrated into the first plate element part, and a second fixing element that is a support is formed in the second plate element part for fixing the first and second plate elements to prevent rotational movement.

2. The plate element according to claim 1 , wherein the first plate element part and the second plate element part are connected to one another such that the first organosheet forms at least a portion of a first outer surface of the plate element and the second organosheet forms at least a portion of a second outer surface of the plate element that is opposite the first outer surface.

3. The plate element according to claim 1 , wherein the first base body and/or the second base body is made of a thermoplastic plastics material.

4. The plate element according to claim 3 , wherein the thermoplastic plastics material of the first base body, and/or
the thermoplastic plastics material of the second base body comprises a fiber reinforcement.

5. The plate element according to claim 1 , wherein the first base body and/or the second base body has a rib structure.

6. The plate element according to claim 1 , wherein the first base body and the second base body each have a rib structure, and
wherein, to form a connection of the first plate element part to the second plate element part, ribs of the rib structure of the first base body are connected to ribs of the rib structure of the second base body.

7. The plate element according to claim 1 , wherein the first plate element part is materially connected to the second plate element part.

8. The plate element according to claim 1 , wherein the first base body is injection-molded onto the first organosheet and/or in that the second base body is injection-molded onto the second organosheet.

9. The plate element according to claim 6 , wherein at least one tensioning strap guide in the form of a groove-shaped recess is formed on the first organosheet or on the second organosheet.

10. The plate element according to claim 1 , wherein at least 70% of fibers contained in the first organosheet and/or in the second organosheet are aligned in a main stress direction (R) of the plate element.

11. The plate element according to claim 9 , wherein, in a region of the at least one tensioning strap guide, the ribs of the rib structure of the first base body and/or the ribs of the rib structure of the second base body are spaced closer together than in a region outside of the region of the at least one tensioning strap guide.

12. The battery module according to claim 1 , wherein at least one tensioning strap is provided which spans the two plate elements and the battery cells arranged between the two plate elements, wherein the tensioning strap is guided in the tensioning strap guide of the plate elements.
