Abstract: A method for estimating a present quality of the energy storage device comprises measuring a first length change of a first surface of the energy storage device; measuring a temperature and/or a second length change of a second surface of the energy storage device; and estimating the present quality of the energy storage device based on the first length change combined with the temperature and/or the second length change of the energy storage device.

Abstract: A method for estimating a consumed lifetime of the energy storage device includes measuring a time-series of an environmental relative humidity and a related temperature of the energy storage device; and estimating, based on the time-series and on a moisture diffusion model of the energy storage device, the consumed lifetime of the energy storage device.
