Abstract

A method, device, and computer-readable medium for operating an electrical energy store is provided. The electrical energy store includes a storage cell for storing electrical energy and a control unit. State variables of the electrical energy store are detected. The state variables are transmitted to a computation unit outside of the electrical energy store. The electrical energy store is operated based on operating parameters provided by the computation unit.

Claims (19)

1. A method for operating an electrical energy store ( 12 ), which comprises a storage cell ( 14 ) for storing electrical energy and a control unit ( 16 ), wherein the control unit ( 16 ) is configured to detect state variables of the electrical energy store ( 12 ), the method comprising:

detecting state variables via the control unit ( 16 );

transmitting the state variables detected by the control unit to a computation unit outside of the electrical energy store ( 12 ), wherein the computation unit determines estimated state variables of the electrical energy store ( 12 ) using the state variables detected by the control unit ( 16 ), and wherein the estimated state variables includes at least one selected from the group consisting of: temperature, current, and electric charge, and

operating the electrical energy store ( 12 ) based on an operating parameter determined by the computation unit using the estimated state variables, wherein the operating parameter is an internal resistance of the electrical store ( 12 ).

2. The method as claimed in claim 1 , wherein the operating parameter provided by the computation unit are determined using the state variables detected by the control unit ( 16 ).

3. The method as claimed in claim 2 , wherein the operating parameter is identified using models, wherein the models are suitable for identifying the estimated state variables of the electrical energy store ( 12 ) from the detected state variables of the electrical energy store ( 12 ) and the operating parameter is identified proceeding from the estimated state variables.

4. The method as claimed in claim 2 , wherein the operating parameter provided by the computation unit are identified by means of neural networks.

5. The method as claimed in claim 1 , wherein the computation unit is a cloud ( 20 ).

6. The method as claimed in claim 5 , wherein the electrical energy store ( 12 ) is located in a vehicle ( 10 ) and a connection between the control unit ( 16 ) and the cloud ( 20 ) is effected via a wireless communication module ( 18 ).

7. The method as claimed in claim 6 , wherein the control unit ( 16 ) stores values of the operating parameter provided by the cloud ( 20 ) and uses these to operate the electrical energy store ( 12 ) until updated values of the operating parameter is available from the cloud ( 20 ).

8. A device configured to operate an electrical energy store ( 12 ), which comprises a storage cell ( 14 ) for storing electrical energy and a control unit ( 16 ), wherein the control unit ( 16 ) is configured to

detect state variables of the electrical energy store ( 12 );

transmit the state variables to a computation unit outside of the electrical energy store ( 12 ), wherein the computation unit determines estimated state variables of the electrical energy store ( 12 ) using the state variables detected by the control unit ( 16 ), and wherein the estimated state variables includes at least one selected from the group consisting of: temperature, current, and electric charge; and

operate the electrical energy store ( 12 ) based on an operating parameter determined by the computation unit using the estimated state variables, wherein the operating parameter is an internal resistance of the electrical store ( 12 ).

9. A non-transitory, computer-readable medium containing instructions that when executed by a computer cause the computer to control an energy store to

detect state variables of the electrical energy store ( 12 );

transmit the state variables to a computation unit outside of the electrical energy store ( 12 ), wherein the computation unit determines estimated state variables of the electrical energy store ( 12 ) using the state variables detected by the control unit ( 16 ), and wherein the estimated state variables includes at least one selected from the group consisting of: temperature, current, and electric charge; and

operate the electrical energy store ( 12 ) based on an operating parameter determined by the computation unit using the estimated state variables, wherein the operating parameter is an internal resistance of the electrical store ( 12 ).

10. An electrical energy store ( 12 ), which comprises the system as claimed in claim 8 .
