Abstract

A motor vehicle includes several battery elements placed in modules of a first type and modules of a second type. The battery elements in each module of first type are grouped together in an assembly such that the battery elements can shift when exposed to a force, while the assembly is deformable. In each module of second type, the battery elements can shift, when exposed to the force, without being damaged while retaining their shape. The modules of first type are installed in a first region of the motor vehicle of a low stiffness compared to a second region, in which a body of the motor vehicle is designed for force-dissipating deformation in the event of an accident, and the modules of second type are installed in the second region, in which the body of the motor vehicle is designed to retain its shape in the event of an accident.

First claim

What is claimed is:

1. A motor vehicle, comprising:
a body;
a module of a first type accommodating battery elements which are grouped to form an assembly which, when exposed to a force, is deformable while the battery elements are able to shift relative to one another, said module of first type being installed in a first region of the motor vehicle of low stiffness in comparison to a second region of the motor vehicle, in which first region the body of the motor vehicle is designed for a force-dissipating deformation in the event of an accident; and
a module of a second type accommodating battery elements, said module of second type being shiftable without causing damage thereto, when exposed to a force, while retaining its shape, said module of second type being installed in the second region, in which the body of the motor vehicle is designed to retain its shape in the event of the accident.

2. The motor vehicle of claim 1 , further comprising a frame, said module of second type being arranged on the frame and/or part thereof.

3. The motor vehicle of claim 1 , further comprising a longitudinal member, said module of second type being arranged longitudinally on the longitudinal member.

4. The motor vehicle of claim 1 , further comprising two longitudinal members in spaced-apart relationship, said module of second type configured to connect the two vehicle longitudinal members in a manner of a cross member.

5. The motor vehicle of claim 1 , further comprising a longitudinal member, said module of second type being connected to the longitudinal member such as to form a section of the longitudinal member.

6. The motor vehicle of claim 5 , wherein the module of second type is connected to the longitudinal member at a surface oriented in or in opposition to a travel direction of the motor vehicle.

7. The motor vehicle of claim 1 , further comprising two of said module of first type, said two modules of first type being arranged adjacent to the module of second type.

8. The motor vehicle of claim 7 , wherein the two modules of first type are arranged transversely to a travel direction of the motor vehicle.

9. The motor vehicle of claim 1 , wherein the module of first type adjoins on two opposite sides modules of the second type.

10. The motor vehicle of claim 1 , further comprising an underfloor, at least one of the modules of first type and second type being connected with the underfloor in a force-fitting manner.

11. The motor vehicle of claim 1 , further comprising a seating area, said module of second type being arranged underneath the seating area.

12. The motor vehicle of claim 1 , further comprising two seating areas, and a tunnel region extending between the two seating areas, said module of first type being arranged underneath the tunnel region.

13. The motor vehicle of claim 1 , further comprising a forward structure, said module of first type and said module of second type being arranged in the forward structure.

14. The motor vehicle of claim 1 , wherein the module of first type is located in a deformation zone of the motor vehicle.
