## Abstract

The presented invention relates to a method for operating an electrical energy store, the ageing behaviour of which is estimated by means of an expected ageing profile, wherein a rapid-charging profile, which is to be used, of the electrical energy store is ascertained depending on a comparison between a detected state of ageing of the electrical energy store and a desired state of ageing, which is determined by means of the expected ageing profile, of the electrical energy store.

## Claims

### Claim 1

A method for operating an electrical energy store (12), the ageing behavior of which has been estimated by means of an expected ageing characteristic (34), the method comprising:
determining a quick-charge profile for the electrical energy store (12) depending on a comparison between a detected state of ageing of the electrical energy store and a setpoint state of ageing of the electrical energy store determined by means of the expected ageing characteristic;
wherein the quick-charge profile is determined in such a way that a future discrepancy between the detected state of ageing of the electrical energy store (12) and the setpoint state of ageing of the electrical energy store (12) determined by means of the expected ageing characteristic (34) is less than an associated discrepancy between the detected state of ageing of the electrical energy store (12) and the setpoint state of ageing of the electrical energy store (12) determined by means of the expected ageing characteristic (34), which discrepancy is to be expected when using a standard quick-charge profile (27).

### Claim 2 (depends on 1)

The method as claimed in claim 1, wherein the determination of the quick-charge profile includes selecting from among a multiplicity of stored quick-charge profiles which differ in terms of their influence on the ageing behavior of the electrical energy store.

### Claim 3 (depends on 1)

The method as claimed in claim 1, wherein the quick-charge profile is determined in such a way that the state of ageing of the electrical energy store detected at a future horizon time point (39) corresponds to an associated state of ageing determined from the expected ageing characteristic (34).

### Claim 4 (depends on 3)

The method as claimed in claim 3, wherein a selection of available quick-charge profiles are presented to user of the electrical energy store (12).

### Claim 5 (depends on 4)

The method as claimed in claim 4, wherein, prior to the selection of the quick-charge profile to be used, the horizon time point (39) or an item of selection information, which correlates with the horizon time point (39), of the available quick-charge profiles is displayed to the user of the electrical energy store (12).

### Claim 6 (depends on 1)
