1. A method for manufacturing a crash frame for a battery compartment for electric drive vehicles, the battery compartment including the crash frame and a battery housing, the battery housing enclosing at least one battery module, the method comprising the steps of:
providing at least two metallic sheets and arranging the at least two metallic sheets on top of each other;
joining the at least two metallic sheets together essentially at the circumference of at least one sheet to form joined sheets;
introducing a medium between at least two sheets of the joined sheets;
applying a pressure to the medium, causing a deformation of at least one sheet of the joined sheets; and
producing a crash frame including a plurality of wall components, each of the wall components comprising the joined sheets and a deformation space between the at least two sheets, the deformation space produced by the deformation of the at least one sheet;
wherein producing the crash frame includes:
after forming the deformation space, bending the joined sheets along at least one bend line to form the plurality of wall components joined at the at least one bend line;
wherein the crash frame including the plurality of wall components is configured such that in an installed position, the battery housing is inserted into the crash frame.
