Abstract
A cooling device for battery cells assembled to form a module, having a base body and an insert which has receptacles for an end portion of the battery cells with recesses in the cell head. The insert together with the base body delimits a flow channel for a temperature control fluid A cooling device of this type permits operationally reliable accommodation of the battery cells with low manufacturing costs and high temperature control performance, without having to take manufacturing tolerances into account in advance. The receptacles form a fluid-tight membrane which encloses the end portion of the battery cells, which membrane is deformable for tolerance compensation of the individual battery cells and rests against the cell bottom when the flow channel is filled.
