Abstract
A state value for a rechargeable battery, for example a lithium-ion battery, is determined on the basis of several aging characteristic variables. The aging characteristic variables comprise at least one current aging value and one future aging value.
Claims17
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,
- 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 depending on a comparison of 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.
An apparatus comprising a processor and a memory, where the processor is designed to load program code from the memory and to execute it, where executing the program code causes the processor to execute:
- 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,
- ascertaining a 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 several application scenarios depending on a comparison of several future aging values, and
- selecting a device into which the battery is to be installed, the selection 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.
