A compressible, planar pressure switch, battery cell module with at least one such pressure switch, rechargeable battery with at least one such battery cell module and method for operating such a battery cell module or such a battery

摘要

The invention relates to a compressible, flat pressure switch (1), with a front (3) and a back (5) and at least one side surface (7), wherein the body of the compressible, flat pressure switch (1) is formed of a porous material , and the body of the pressure switch (1) at least one contact plate (9) on or in the front (3), and at least one contact plate (11) on or in the back (5) of the body of the compressible, surface pressure switch (1), wherein the respective two contact plates (9, 11) are arranged opposite to each other, and wherein one of the respective contact plates (9) has a spike-like or oblong elevation (13) with a tapering, distal end facing in the direction the other contact plate (11) points. In an alternative embodiment, both opposing contact plates (9, 11), in each case one or more of the aforementioned mandrel-like or elongated elevation 13 with tapered, distal end, each facing in the direction of the other contact plate 9, 11 and have. The invention further relates to a battery cell module with the compressible, planar pressure switch (1), a rechargeable battery with the battery cell module and a method for operating a battery cell module according to the invention or a rechargeable battery according to the invention.
