[0028]The two functions 3, 4 reflect two different boundary conditions A and B. In a first step, the secondary battery is operated under boundary conditions A from a first charge throughput a to a second charge throughput b. The boundary condition changes from A to B at the first endpoint value 5. The change from boundary condition A to B describes in this example a temperature change of 5° C. from the original operating temperature.
[0029] For the continuation under boundary condition B for the same capacity loss as the first end point value 5 of boundary condition A, an intersection point with the function for boundary condition B is determined. This point of intersection is now used as the second starting value 6 for the secondary battery operation under boundary condition B. The secondary battery is now operated under boundary condition B from the second charge throughput b to the third charge throughput c. The second charge flux b moves to the fourth charge flux b2 w...
