Abstract

A method for using an electrochemical energy storage device within a specifiable usage plan time period so as to optimize the service life is provided. The calendar aging constitutes a variable which influences the service life of the energy storage device and which is expressed in the form of a nonlinear function based on the fill state and the temperature of the energy storage device, the temperature being influencable by at least one charging and/or discharging process.
