A pressure sensing cell for use in a battery pack that has a plurality of linearly stacked battery cells. The pressure sensing cell includes an at least partially fluid-filled and fluid-proof flexible pouch container having a plurality of electric feedthroughs, at least one pressure-sensitive member having a plurality of electric pins, that is arranged within the flexible pouch container, and a plurality of electric lines that electrically connect the plurality of electric feedthroughs and the plurality of electric pins. A battery pack is provided that includes a plurality of linearly stacked battery cells and at least one such pressure sensing cell. A method for at least one of detecting upcoming thermal runaway, supporting the evaluating of a state of safety, and supporting the evaluating of a state of health of a battery pack having a plurality of linearly stacked battery cells employs at least one such pressure sensing cell.
