COOLING DEVICE FOR BATTERY CELLS ASSEMBLED INTO A MODULE

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 the exception of the cell head (), the insert () together with the base body () delimiting a flow channel () for a temperature control fluid, is described. In order to design a cooling device of this type in such a way as to permit 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, it is proposed that the receptacles () form a fluid-tight membrane () which encloses the end portion () of the battery cells (), which membrane () is designed to be deformable for tolerance compensation of the individual battery cells () and is resting against the cell bottom () when the flow channel () is filled.
