wherein the flange of each wall element comprises an opening for passage of a threaded portion of a screw which is screwed into the threaded bore of an adjacent wall element;
wherein the opening and the through bore of each wall element lie on a common axis oriented in the stacking direction; and
wherein the flange of each wall element comprises, in a region of intersection with an axis running through the threaded bore of this wall element, a continuous region for covering the through bore of the adjacent wall element.
3 . The battery housing according to claim 2 , wherein the wall elements are each designed in the form of a casting, and wherein the bores of the pair are formed in domes formed on the wall element.
4 . The battery housing according to claim 3 , wherein each wall element comprises a base plate extending in the stacking direction and perpendicularly thereto.
5 . The battery housing according to claim 4 , wherein at least one of: the threaded bore and the through bore of a pair are arranged next to each other perpendicular to the stacking direction and parallel to an extent of a base plate of the wall element and the threaded bores and the through bores extend in the stacking direction.
6 . The battery housing according to claim 5 , wherein the through bore of each wall element is formed in the stacking direction for passage of a tool.
7 . The battery housing according to claim 6 , wherein the pairs of bores are arranged one above each of the other pairs of bores in the stacking direction.
8 . The battery housing according to claim 7 , wherein the threaded bore of each wall element is designed as a continuous bore.
9 . The battery housing according to claim 3 , wherein the wall elements are each designed in the form of a high-pressure die casting.
10 . The battery housing according to claim 3 , wherein the bores of the pair are formed in domes cast on each of the wall elements.
11 . The battery housing according to claim 3 , wherein the bores of the pair are formed on an outer side of each of the wall elements.
12 . The battery housing according to claim 4 , wherein each of the base plates extends in the stacking direction from a first side to a second side.
13 . The battery housing according to claim 12 , wherein at least one reinforcing rib extends perpendicularly from each of the base plates on an outer side of each of the wall elements.
14 . The battery housing according to claim 12 , wherein the at least one reinforcing rib extends perpendicularly to the stacking direction, and comprises in the stacking direction at least one recess for passage of a tool.
15 . The battery housing according to claim 14 , wherein the stacking direction is at the level of the bores, and wherein the at least one recess for the passage of a tool is configured to receive a tool blade of a screwdriver.
16 . The battery housing according to claim 6 , wherein each of the through bores are configured to receive a tool blade of a screwdriver.
17 . A vehicle-Vehicle battery comprising:
at least one battery cell, characterized by a battery housing, wherein the battery housing comprises:
at least two wall elements, stacked one above each of the other wall elements in a stacking direction, in order to form in each case a housing wall;
