Abstract: An accumulator arrangement may include a plurality of battery cells respectively having a plurality of bearing surfaces. The plurality of battery cells may be stacked in a stacking direction to form at least one battery block. The arrangement may further include at least one cooling device that may include a plurality of cooling elements through which a cooling fluid is flowable. A respective cooling element may be arranged between and abut against adjacent battery cells and clamped thereto. The at least one cooling device may further include at least one fluid guide tube having at least one fluid guide duct through which the cooling fluid is flowable. The at least one fluid guide tube may include at least one deformable adaptation area that may, via deformation, compensate at least one of an expansion and a compression of the at least one battery block in the stacking direction.
