Abstract
A battery system having at least a pair of battery modules, each battery module having a base plate and a cell stack secured on a base surface of the base plate. A first offset is arranged on a first side of the base plate and a first section is arranged on a second side opposite the first side. First threaded holes are arranged in the first offset and in the first section, parallel to the direction of extent of the first offset and of the first section. The battery modules are connected to one another via the auxiliary frame by screwing into the first threaded holes through through-holes arranged in the auxiliary frame.
Claims19
A battery system comprising:
- a plurality of battery modules, each of the battery modules comprising a base plate and a group of cells on a base surface of the base plate, the cells on the base surface of the base plate being arranged adjacent each other in a first direction, the base plate having:
- a first offset extending from a first side of the base plate in a second direction perpendicular to the first direction beyond a footprint of the group of cells and extending along the group of cells in the first direction;
- a first section extending from a second side of the base plate opposite the first side in the second direction beyond a footprint of the group of cells and extending along the group of cells in the first direction;
- and
- a first threaded hole arranged in each of the first offset and the first section, the first threaded holes respectively extending through the first offset and the first section in the first direction;
- and
- an auxiliary frame having auxiliary frame through-holes which correspond to the first threaded holes to connect the battery modules to one another,
- wherein the first offset protrudes above the base surface of the base plate in a third direction perpendicular to the first and second directions to be above the first section of the base plate such that a bottom edge of the first offset of a second one of the battery modules is arranged spatially above a top edge of the first section of a first one of the battery modules in an installed position of the battery system.

A battery system comprising:
- a plurality of battery modules, each of the battery modules having a base plate and a cell stack on a base surface of the base plate, the cell stack comprising a plurality of cells arranged adjacent each other in a first direction, the base plate having a first offset extending from a first side of the base plate in a second direction perpendicular to the first direction and protruding above the base surface in a third direction perpendicular to the first and second directions, a first section extending from a second side of the base plate opposite the first side in the second direction, a first threaded hole arranged in each of the first offset and the first section that respectively extend though the first offset and the first section in the first direction, second threaded holes arranged in the first offset that extend through the first offset perpendicularly to the base surface in the third direction, and second through-holes arranged in the first section that extend through the first section perpendicularly to the base surface in the third direction;
- a first auxiliary frame arranged at a first end of the battery modules and having first auxiliary frame through-holes which correspond to the first threaded holes to connect the battery modules to one another;
- a second auxiliary frame arranged at a second end of the battery modules opposite the first end of the battery modules and having second auxiliary frame through-holes which correspond to the first threaded holes to connect the battery modules to one another;
- and
- a housing having a housing shell, a housing cover, housing through-holes, and housing threaded holes which respectively correspond to the second through-holes and to the second threaded holes to connect the battery modules to the housing shell,
- wherein, in an installed state, the first offset of a second one of the battery modules is over the first section of a first one of the battery modules, and the second threaded holes in the first offset of the second one of the battery modules are respectively aligned with the second through-holes in the first section of the first one of the battery modules.
