Abstract

A battery arrangement for structurally integrating batteries in a vehicle, in particular an aircraft or spacecraft, includes at least one battery, two supporting cooling plates between which the at least one battery is held on both sides via battery holders, and connecting rods which connect the two cooling plates to one another.

First claim

The invention claimed is:

1. A battery arrangement for structurally integrating batteries in a vehicle, the battery arrangement comprising:
at least one battery;
two supporting cooling plates integrally produced from a metal material having a multiplicity of fluid channels, wherein the at least one battery is held between the two supporting cooling plates on both sides via battery holders;
a plurality of connecting rods which connect the two supporting cooling plates to one another; and
at least two side walls which close off the supporting cooling plates with the at least one battery in between, each of the at least two side walls comprising fastening lugs used to mount or couple the battery arrangement inside the vehicle, wherein at least one of the side walls comprises a plurality of cooling ribs configured as a heat exchanger for dissipating heat produced by the batteries to outside the battery arrangement;
wherein each respective cooling plate is connected to the respective battery holder via shear pins.

2. The battery arrangement according to claim 1 , wherein the shear pins contain a plastic material.

3. The battery arrangement according to claim 1 , wherein the at least one battery is mounted on both sides in the battery holders in a form-fitting manner.

4. The battery arrangement according to claim 1 , wherein the battery holders are in a form of plates having a battery receptacle for accommodating the at least one battery on one side.

5. The battery arrangement according to claim 1 , further comprising:
two current collectors to which the at least one battery is respectively electrically coupled on both sides on which the battery is held by the battery holders.

6. The battery arrangement according to claim 1 , wherein the connecting rods contain a metal material.

7. The battery arrangement according to claim 1 , wherein the side walls close off a multiplicity of cooling plates with batteries in between.

8. An aircraft or spacecraft having a battery arrangement for structurally integrating batteries in an aircraft or spacecraft, the battery arrangement comprising:
at least one battery;
two supporting cooling plates integrally produced from a metal material having a multiplicity of fluid channels, wherein the at least one battery is held between the two supporting cooling plates on both sides via battery holders;
a plurality of connecting rods which connect the two supporting cooling plates to one another; and
at least two side walls which close off the supporting cooling plates with the at least one battery in between, each of the at least two side walls comprising fastening lugs used to mount or couple the battery arrangement inside the vehicle, wherein at least one of the side walls comprises a plurality of cooling ribs configured as a heat exchanger for dissipating heat produced by the batteries to outside the battery arrangement;
wherein each respective supporting cooling plate is connected to the respective battery holder via shear pins.

9. The aircraft or spacecraft according to claim 8 , wherein the battery arrangement is coupled to the aircraft or spacecraft via the at least two side walls which close off the cooling plates with the at least one battery in between.
