Abstract

The invention relates to a method for aging-optimized charging of an energy store of a motor vehicle, comprising:detecting a predetermined number of consecutive full charging processes of the energy store;creating a use profile of the energy store on the basis of discharging processes of the energy store between the consecutive full charging processes;determining whether the created use profile requires a full charging process as the next charging process, and, if the created use profile does not require a full charging process as the next charging process, proposing the charging strategy for the aging-optimized charging, wherein the charging strategy specifies a partial charging process of the energy store for at least the next charging process, in which the energy store is charged up to a predetermined partial charging limit of the operating capacity of the energy store that is smaller than the full charging limit.
