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.

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).

- estimate an ageing behavior by means of an expected ageing characteristic (34);
- determine a quick-charge profile for an 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;
