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. Furthermore, the first separating element 12 and the second separating element 14 enclose a chamber 16 between them, and the chamber 16 is filled with a flame-retarding and / or insulating fluid.

Description

technical field [0001] The invention relates to a separator for battery modules. The partition device comprises a first partition element and a second partition element, which are arranged side by side one above the other. The invention also relates to a battery module comprising a separator according to the invention and a motor vehicle having a battery module according to the invention. Background technique [0002] Battery modules with battery cells, especially lithium-ion cells, generate heat during the charging and discharging phases. If the temperature reaches a critical value, autoignition occurs, which can also be referred to as thermal runaway propagation / expansion. In addition, the battery cells also expand during the charge and discharge phases, which may also be referred to as bulge. In order to prevent thermal runaway of one battery cell from spreading to the nearest battery cell or damage due to expansion of the battery cells, it is known from the prior art ...
