Abstract

A method for operating a storage device for storing electrical energy, having at least two storage cells. The storage cells are charged with the aid of a physical charge quantity provided by an electrical charging device, and a physical variable is monitored in each case in the storage cells. As a function of the monitored variables, a control signal is transmitted to the charging device for controlling same, and the charge quantity is successively reduced as a function of the control signal. A related storage device for storing electrical energy is also described.

Claims

1-6. -6. (canceled)

7. A method for operating a storage device for storing electrical energy, having at least two storage cells, which are charged with the aid of a physical charge quantity provided by an electrical charging device, the method comprising:

monitoring a physical variable in the at least two storage cells;

transmitting, as a function of the monitored variables, a control signal for controlling the charging device to the charging device; and

successively reducing the charge quantity as a function of the control signal.

8. The method of claim 7, wherein the storage cells are at least partially discharged as a function of the control signal.

9. The method of claim 7, wherein the electric physical charge quantity is at least one of an electrical charging current and an electrical charging voltage for inductively charging the storage cells.

10. The method of claim 7, wherein the charge quantity is reduced, at least partially, corresponding to a step function.

11. The method of claim 7, wherein the charge quantity is reduced, at least partially, corresponding to an exponential function.

12. A storage device for storing electrical energy, comprising:

at least two storage cells, which are chargeable with the aid of a physical charge quantity provided by an electrical charging device;

a monitoring device to monitor a physical variable in each case in the storage cells; and

a control device to output a control signal, which is a function of the monitored variables, to control the electrical charging device to successively reduce the charge quantity.
