Abstract

A battery carrier for accommodating at least one battery for an electric motor vehicle is disclosed having tension spring elements being arranged underneath a base of the battery carrier. The tension spring elements press a temperature adjustment element, which is likewise arranged underneath the base, onto the base, such that heat conduction from the base into the temperature adjustment element takes place.

First claim

1 .- 11 . (canceled)

12 . A battery carrier for accommodating at least one battery for an electric motor vehicle, comprising:
a trough-shaped inner space having a base for accommodating batteries therewithin and arranged in abutting contact with the base; the base having an outer side; a plurality of temperature adjustment elements being arranged in areal abutting contact with the base; wherein extensions are embodied as protruding lugs on a planar region of the outer side of the base; and, at least one spring element coupled to the extensions in such a manner that the temperature adjustment elements are pressed onto the base.

13 . The battery carrier of claim 12 , wherein the temperature adjustment elements are embodied as cooling ducts, and wherein the cooling ducts are produced from lightweight metal or plastic.

14 . The battery carrier of claim 12 , wherein the temperature adjustment elements are embodied as latent heat stores.

15 . The battery carrier of claim 12 , wherein the spring element is a tension spring element, the tension spring element are embodied as a bracket component.

16 . The battery carrier of claim 15 , wherein the base is produced as an extruded component, the temperature adjustment elements being arranged in the hollow chamber.

17 . The battery carrier of claim 12 , wherein the base is a base plate.

18 . The battery carrier of claim 15 , wherein the extensions are produced in one piece and in a materially integral manner in the base, wherein the extensions are as a separate component coupled to the base.

19 . The battery carrier of claim 18 , wherein the base is formed from light-weight metal and/or wherein a thermally conductive paste is arranged between the base and the battery base and/or between the base and the temperature adjustment element.

20 . The battery carrier of claim 19 , wherein an underride guard is arranged at a spacing from the tension spring element.

21 . The battery carrier of claim 12 , wherein the base is a hollow component of closed cross section, a top side forming the base of the trough of the battery carrier and a bottom side forming an underride guard.

22 . The battery carrier of claim 21 , wherein the ribs are formed on the bottom side.

23 . The battery carrier of claim 12 , wherein the cooling ducts are extruded components.

24 . The battery carrier of claim 15 , wherein the base is produced as an extruded component in cross section as a hollow component with a hollow chamber.

25 . The battery carrier of claim 15 , wherein the extensions are produced in one piece and in a materially integral manner in the base by embossing.
