Abstract
The invention relates to a battery (10) having a plurality of battery cells (12) which form a cell stack (14) which stands on a bottom plate (18) of the battery (10). At least one wedge (20, 22) is provided to brace the battery cells (12) against one another. The at least one wedge (20, 22) and the cell stack (14) are secured in their position relative to the bottom plate (18) by at least one bracket (24) which is mounted to the bottom plate (18). Manufacturing tolerances of the battery cells (12) can be compensated by the at least one wedge (20, 22), and the bracket (24) secures both the wedge (20, 22) and the cell stack (14).

A battery formed as an energy store, said battery comprising:
- a bottom plate;
- a plurality of battery cells arranged to form a cell stack which rests on the bottom plate, said battery cells being configured in the shape of a flat block having narrow sides which stand on the bottom plate;
- at least one wedge bracing of the battery cells of the cell stack against each other such that a force acts on contacting sides of the battery cells to hold the cell stack together;
- and
- at least one bracket mounted on the bottom plate and securing the at least one wedge and the cell stack in their position in relation to the bottom plate, said at least one bracket having a U-shaped configuration and spanning the cell stack.
