Battery carrier for an electric motor vehicle with a cooling system
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.
1. 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,
wherein the temperature adjustment elements are embodied as cooling ducts, and
wherein the cooling ducts are produced from lightweight metal or plastic.
2. The battery carrier of claim 1 , wherein the temperature adjustment elements are embodied as latent heat stores.
3. The battery carrier of claim 1 , wherein the spring element is a tension spring element, the tension spring element embodied as a bracket component.
4. The battery carrier of claim 3 , wherein the base is produced as an extruded component, the temperature adjustment elements being arranged in a hollow chamber of the base.
5. The battery carrier of claim 1 , wherein the base is a base plate.
6. The battery carrier of claim 3 ,
wherein the extensions are produced in one piece and in a materially integral manner in the base, or
wherein the extensions are as a separate component coupled to the base.
7. The battery carrier of claim 6 , 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 elements.
8. The battery carrier of claim 7 , wherein an underride guard is arranged at a spacing from the tension spring element.
9. The battery carrier of claim 1 , 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.
10. The battery carrier of claim 9 , wherein ribs are formed on the bottom side.
11. The battery carrier of claim 1 , wherein the cooling ducts are extruded components.
12. The battery carrier of claim 3 , wherein the base is produced as an extruded component in cross section as a hollow component with a hollow chamber.
13. The battery carrier of claim 3 , wherein the extensions are produced in one piece and in a materially integral manner in the base by embossing.
14. 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,
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.
15. 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,
wherein the spring element is a tension spring element, the tension spring element embodied as a bracket component, and
wherein the extensions are produced in one piece and in a materially integral manner in the base by embossing.
