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 (35)

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 ).

2. 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.

3. 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 ).

4. 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 ).

5. 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 ).

6. The method as claimed in claim 1 , wherein the electrical energy store ( 12 ) comprises a battery of an electric vehicle ( 10 ).

7. An apparatus, configured to

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;

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 ).

8. A non-transitory computer-readable media containing instructions that when executed by a computer cause the computer to

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;

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 ).

9. 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 setpoint state of ageing of the electrical energy store by means of the expected ageing characteristic ( 34 );

detecting a stage of ageing of the electrical energy store;

comparing the state of ageing and the setpoint state of ageing to determine a real-time discrepancy;

selecting a quick-charge profile for the electrical energy store ( 12 ) based on the real-time discrepancy;

wherein in the event the quick-charge profile is different than a standard quick-charge profile, 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 ) is less than an associated discrepancy expected when using the standard quick-charge profile ( 27 ).

10. An apparatus, configured to:

determine a setpoint state of ageing of an electrical energy store by means of an expected ageing characteristic ( 34 );

detecting a stage of ageing of the electrical energy store;

compare the state of ageing and the setpoint state of ageing to determine a real-time discrepancy;

select a quick-charge profile for the electrical energy store ( 12 ) based on the real-time discrepancy;

wherein in the event the quick-charge profile is different than a standard quick-charge profile, 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 ) is less than an associated discrepancy expected when using the standard quick-charge profile ( 27 ).

11. A non-transitory computer-readable media containing instructions that when executed by a computer cause the computer to:

estimate an ageing behavior by means of an expected ageing characteristic ( 34 );

determine a setpoint state of ageing of an electrical energy store based on the expected ageing characteristic ( 34 );

detecting a stage of ageing of the electrical energy store;

compare the state of ageing and the setpoint state of ageing to determine a real-time discrepancy;
