Abstract

An underbody of an electrically driven motor vehicle, with a vehicle supporting structure, which is bounded laterally in a transverse direction of the vehicle by two vehicle sills between which a multiplicity of battery modules is arranged, which battery modules are assigned a battery supporting structure and at least one battery temperature control device, and with supply and removal devices for a temperature control medium. The supply and removal devices for the temperature control medium are arranged in the region of the vehicle sills.

First claim

What is claimed is:

1. An underbody ( 1 ; 41 ) of an electrically driven motor vehicle, comprising:
a. a vehicle supporting structure ( 3 ; 43 ), said vehicle supporting structure comprising two vehicle sills ( 5 ; 45 ) located laterally in a transverse direction of the vehicle;
b. a plurality of battery modules ( 11 ; 51 ) arranged between the sills;
c. a battery supporting structure ( 13 ; 53 ) supporting the battery modules;
d. at least one battery temperature control device ( 15 ; 55 ) assigned to the battery modules, the battery temperature control device comprising a cooling device operated with a cooling liquid that cools the battery modules; and
e. one or more supply and/or removal devices ( 17 ; 57 ) for the cooling liquid, wherein the supply and/or removal devices ( 17 ; 57 ) for the cooling liquid are arranged in the region of the vehicle sills ( 5 ; 45 ).

2. The underbody as claimed in claim 1 , wherein the supply and/or removal devices ( 17 ; 57 ) for the temperature control medium are arranged on outer longitudinal sides of a battery frame ( 20 ; 60 ) for the battery modules ( 11 ; 51 ).

3. The underbody as claimed in claim 1 , wherein the one or more supply and/or removal devices ( 17 ; 57 ) for the temperature control medium are arranged in the transverse direction of the vehicle between the battery supporting structure ( 13 ; 53 ) and one of the vehicle sills ( 5 ; 45 ).

4. The underbody as claimed in claim 3 , wherein the supply or removal device ( 17 ) for the temperature control medium is arranged below a connecting region ( 30 ) which connects the battery supporting structure ( 13 ) to the vehicle sill ( 5 ).

5. The underbody as claimed in claim 3 , wherein the supply or removal device ( 57 ) for the temperature control medium is arranged in a connecting region ( 70 ) which connects the battery supporting structure ( 53 ) to the vehicle sill ( 45 ).

6. The underbody as claimed in claim 1 , wherein the battery supporting structure ( 15 ; 55 ) comprises a base structure and/or sealing structure ( 24 ; 64 ) which is arranged in a z-direction of the vehicle between a temperature control base structure ( 18 ; 58 ) and the battery modules ( 11 ; 51 ).

7. The underbody as claimed in claim 6 , wherein the temperature control base structure ( 18 ; 58 ) is arranged in the z direction of the vehicle between a base plate ( 26 ; 66 ) and the base structure and/or sealing structure ( 24 ; 64 ) of the battery supporting structure ( 15 ; 55 ).

8. A motor vehicle comprising an underbody ( 1 ; 41 ) as claimed in claim 1 .
