Embodiment Construction

[0026] figure 1A plan view of a schematic illustration of an exemplary embodiment of a motor vehicle according to the invention is shown. The motor vehicle 1 here has two longitudinal supports 5 between which a plurality of battery modules 3 of a first type and a plurality of battery modules 4 of a second type are arranged. Attached to the vehicle longitudinal carrier 5 are modules 4 of the second type. A second type of module 4 is a compact arrangement of battery elements 2 , ie, battery cells, which are embedded by the frame 11 of the module into the longitudinal carrier and transverse carrier structure. The frame 11 is mainly used to achieve the rigidity of the module 4 of the second type, so that the module can move as a whole under the application of force and the individual battery elements 2 are not damaged. Due to the stable design, the second type of module 4 can at the same time serve as a structural reinforcement of the vehicle. For this purpose it is possible, f...

Abstract

The invention relates to a motor vehicle (1) having a plurality of battery elements (2) which are present in modules of a first type (3) and of a second type (4), each containing a plurality of battery elements (2), wherein, in a module of the first type (3), the battery elements are arranged in a group in such a way as to be able to be shifted relative to one another, depending on an introduction of force, with the group being deformed, and, in a module of the second type (4), the arrangement of the battery elements (2) is able to be shifted, depending on an introduction of force, without any damage being caused but only while retaining its shape, wherein battery elements (2) are installed as modules of the first type (3) in a first region of the motor vehicle (1) having a low stiffness in comparison to a second region of the motor vehicle (1), in which first region a body of the motor vehicle (1) is designed for force-dissipating deformation in the event of an accident, and battery elements (2) are installed as modules of the second type (4) in the second region of the motor vehicle (1) having an increased stiffness in comparison to the first region of the motor vehicle (1), in which second region the body of the motor vehicle (1) is designed to retain its shape in the event of an accident, in order to increase the operational safety of the motor vehicle (1) and to reduce the weight.

Description

technical field [0001] The invention relates to a motor vehicle with a plurality of battery elements according to the preamble of claim 1 . Background technique [0002] The storage of electrical energy plays an increasing role in motor vehicles. The battery elements used to store energy in motor vehicles are often arranged in large battery systems. These battery systems generally have a plurality of battery elements and are installed in the vehicle in an area where forces are low. So either the battery size is limited or the battery components must be protected by robust protective measures. This in turn leads to great overweight. Solutions describing so-called crash-proof battery systems are known. These battery systems comprise modules having, for example, a trapezoidal shape and thus allow force-relieving, group-deformed movements without damaging the battery elements. The additional energy can be reduced by means of additional crash profiles. [0003] Thus, for ex...
