17. A method for ascertaining a state value in connection with aging of a rechargeable battery, where the method comprises:
ascertaining a current aging value of the battery,
ascertaining a future aging value of the battery by means of an aging model and based on the current aging value, and
ascertaining the state value of the battery based on several aging characteristic variables which comprise at least the current aging value and the future aging value,
selecting a specific application scenario from the several application scenarios depending on a comparison of the several future aging values, and
installing the battery or at least one cell of the battery into a device which is selected depending on the selection of the specific application scenario, where different application scenarios are associated with different devices,
wherein the aging model ascertains several future aging values based on several anticipated load profiles,
wherein the several anticipated load profiles correspond to several application scenarios, and
where the several application scenarios are selected from the following group: static energy store in a microgrid; energy store for mobile applications; low-load energy store; energy store for light electric vehicles; energy store for electric passenger cars; indoor application; and outdoor application.
