Abstract

A battery arrangement for the structural integration of batteries in a vehicle, in particular an aircraft or spacecraft, includes at least one battery; and two supporting, multi-layered structural laminates, between which the at least one battery is held on both sides via battery holders, wherein each multi-layered structural laminate has a cooling plate layer and a current collector layer, wherein the at least one battery is coupled electrically to the current collector layer.

First claim

The invention claimed is:

1. A battery arrangement for structural integration of batteries in a vehicle comprising:
at least one battery; and
two supporting, multi-layered structural laminates comprising battery holders, between which the at least one battery is held on both sides;
wherein each multi-layered structural laminate has a cooling plate layer and a current collector layer, the at least one battery being coupled electrically to the current collector layer;
wherein at least one of the multi-layered structural laminates comprises a plurality of electrical insulating layers, which are arranged on both sides around the cooling plate layer; and
wherein a multiplicity of fluid ducts from a metal material is integrated within each cooling plate layer.

2. The battery arrangement according to claim 1 , wherein the multi-layered structural laminates each comprise a signal conducting layer to which the at least one battery is electrically coupled.

3. The battery arrangement according to claim 1 , wherein the multi-layered structural laminates each comprise at least one electrical insulating layer.

4. The battery arrangement according to claim 1 , wherein the cooling plate layer in each case forms a core of the multi-layered structural laminate.

5. The battery arrangement according to claim 1 , wherein at least one of the multi-layered structural laminates comprises a plurality of current collector layers and/or signal conducting layers, which are arranged on both sides around the cooling plate layer.

6. The battery arrangement according to claim 1 , wherein the at least one battery is coupled at least on one side via an electrically conductive spring to the current collector layer.

7. The battery arrangement according to claim 1 , wherein the battery holders are designed with a battery receptacle for receiving the at least one battery on one side.

8. The battery arrangement according to claim 1 , wherein the at least one battery is fastened to the battery holder via an integrally bonded connection.

9. The battery arrangement according to claim 1 , comprising
at least two cover plates which close off the multi-layered structural laminates with the at least one battery lying in between.

10. The battery arrangement according to claim 9 , wherein the cover plates close off a multiplicity of multi-layered structural laminates with batteries lying in between.

11. An aircraft or spacecraft with a battery arrangement for structural integration of batteries in an aircraft or spacecraft, the battery arrangement comprising:
at least one battery; and
two supporting, multi-layered structural laminates comprising battery holders, between which the at least one battery is held on both sides;
wherein each multi-layered structural laminate has a cooling plate layer and a current collector layer, the at least one battery being coupled electrically to the current collector layer;
wherein at least one of the multi-layered structural laminates comprises a plurality of electrical insulating layers, which are arranged on both sides around the cooling plate layer; and
wherein a multiplicity of fluid ducts from a metal material is integrated within each cooling plate layer.

12. The aircraft or spacecraft according to claim 11 , wherein the battery arrangement forms part of a structural component of the aircraft or spacecraft.
