Abstract

A method and a device for using an electrochemical energy store so as to optimize the service life is provided. The cyclical aging of the energy store is expressed in the form of a nonlinear function based on the temperature which can be influenced by a charging and/or discharging process of the energy store and the energy throughput. The nonlinear function is linearly approximated in order to determine the cyclical aging in each interval which can be specified for subdividing a specifiable usage planning period and is used to calculate a service life-optimizing plan for using the energy store.
