Abstract

A separating device 10 for a battery module 27. The separating device 10 includes a first separating element 12 and a second separating element 14, which are arranged congruently with respect to one another and adjacent one another. The first separating element 12 and the second separating element 14 are formed from a heat-conducting material. Furthermore, the two separating elements 12, 14 enclose a chamber 16 and the first separating element 12 and the second separating element 14 have embossments 18; 19 corresponding to one another for forming the chamber 16, wherein the embossments 18 of the first separating element 12 extend away from the second separating element 14 and the embossments 19 of the second separating element 14 extend away from the first separating element 12. The embossments (18; 19) are arranged opposite one another, and the chamber (16) is divided into a plurality of chamber region (16a, 16b, 16c) formed by the embossments (18; 19) of the first separating element (12) and the second separating element (14).

Description

technical field [0001] The present invention relates to a separator for battery modules. The separating device comprises a first separating element and a second separating element, which are arranged next to one another in a coinciding / overlapping manner. The first spacer element and the second spacer element are formed from a thermally conductive material. The invention also relates to a battery module comprising the separator according to the invention and to a motor vehicle with the battery module according to the invention. Background technique [0002] A battery module with battery cells, in particular lithium-ion cells, heats up during the charging and discharging phases. If the temperature reaches a critical value, auto-ignition occurs, which can also be referred to as thermal runaway propagation / expansion. In addition, the battery cells also expand during the charging and discharging phases, which may also be referred to as bulging. In order to prevent thermal ru...
