Problems solved by technology

[0004] In order to form such a battery housing for battery modules arranged one above the other in several layers in a correspondingly airtight manner or to provide the battery housing with sufficient stability and rigidity in the event of force loading caused by an accident, it is necessary extensive structural and correspondingly expensive measures
In addition, in the event of force loading caused by an accident, the leak-tightness of the battery housing must be ensured with great structural effort.

Abstract

The invention relates to a battery (B) for an electric drive of a motor vehicle, comprising a plurality of battery modules (1) which are arranged in an associated layer (2, 3, 4, 5) and are accommodated in at least one associated battery housing (8). In order to produce a battery which is optimized both in terms of its manufacture and also in terms of sealing tightness and properties in the eventof a crash, the battery housing (8) is accommodated in a protective housing (14) of the battery (B).

Description

technical field [0001] The invention relates to a battery for an electric drive of a motor vehicle according to the preamble of claim 1 . The invention also relates to a protective housing for such a battery and to a motor vehicle having such a battery. Background technique [0002] The vast majority of batteries for electric drives of motor vehicles are today installed in the floor area of ​​the passenger compartment. For examples of such installations, reference is made to the documents DE 10 2012 015 919 A1 and DE 10 2015 014 033 A1, in which the corresponding battery modules each comprising a plurality of interconnected battery cells are arranged in one layer or in one plane and is received in the battery housing. This known design is also very expensive due to the active cooling required with refrigerant. Furthermore, since the battery housing is often relatively difficult to seal, the enormous size of the battery creates constraints in terms of design and production...
