Abstract
Official abstract text for this publication.
A battery cell, in particular a lithium-ion battery cell, includes a housing, at least two electrical storage elements and a conductive cooling sheet metal. The at least two storage elements and the conductive cooling sheet metal are situated in the housing.
First claim
Opening claim text (preview).
What is claimed is: 1. A battery cell, comprising: a housing; at least two electrical storage elements; and a conductive cooling sheet metal, wherein the at least two electrical storage elements and the conductive cooling sheet metal are situated in the housing, wherein the conductive cooling sheet metal includes a first conductive cooling sheet metal section, the first conductive cooling sheet metal section being disposed between the at least two electrical storage elements, and wherein the conductive cooling sheet metal includes a deformation, the deformation connecting the first conductive cooling metal section and a second conductive cooling sheet metal section, the deformation rising up from a plane of the conductive cooling sheet metal and being contained within the housing; and a molding compound, wherein the housing includes an opening, through which the second conductive cooling sheet metal section of the cooling sheet metal engages, and which is sealed off by the molding compound. 2. A battery cell, comprising: a housing; at least two electrical storage elements; and a conductive cooling sheet metal; wherein the at least two electrical storage elements and the conductive cooling sheet metal are situated in the housing, wherein the conductive cooling sheet metal includes a first conductive cooling sheet metal section, the first conductive cooling sheet metal section being disposed between the at least two electrical storage elements, and wherein the conductive cooling sheet metal includes a deformation, the deformation connecting the first conductive cooling metal section and a second conductive cooling sheet metal section, the deformation rising up from a plane of the conductive cooling sheet metal and being contained within the housing, wherein the conductive cooling sheet metal includes a third conductive cooling sheet metal section, the third conductive cooling sheet metal section being located outside of the housing on a heat sink that has a cooling fluid flowing therethrough, and wherein the conductive cooling sheet metal is fixed in the third conductive cooling sheet metal section on the heat sink. 3. The battery cell as recited in claim 2 , wherein the conductive cooling sheet metal includes at least one perforation in the third conductive cooling sheet metal section, the perforation extending from a first planar surface of the cooling sheet metal to an opposite, second planar surface of the cooling sheet metal. 4. The battery cell as recited in claim 3 , wherein the heat sink engages through the at least one perforation of the conductive cooling sheet metal. 5. The battery cell as recited in claim 4 , wherein the at least one perforation of the conductive cooling sheet metal includes a sleeve that is open on both sides. 6. The battery cell as recited in claim 5 , wherein exactly one conductive cooling sheet metal and exactly two electrical storage elements are situated in the housing.
