Abstract

The invention relates to a clamping device for clamping a cell stack having multiple battery cells disposed next to each other in a stacking direction (x), wherein the clamping device comprises at least one fastening element for fastening the clamping device to a battery housing, and first and second end plate units, wherein at least the first end plate unit includes an end plate which is firmly connected to the at least one fastening element and a deformation plate. The deformation plate is configured such that the deformation plate can be deformed by a deformation force (F) applied to the deformation plate in the case of a cell stack received in the clamping device when at least one battery cell of the cell stack swells.
