In the circuit arrangement at least one inductive component and at least one capacitive component are arranged, forming a tuned circuit with the memory unit. The method has the following steps of energizing the tend circuit by temporary charging of the capacitive component, the energizing being carried out by an energizing device electrically supplied by the memory unit, and determining a time-dependent voltage change at the capacitive component after terminating the energizing and determining the characteristic status parameter from the time-dependence of the voltage change. The invention further relates to a corresponding electrical circuit arrangement and an electrical memory, including such a circuit arrangement.

The intermediate circuit capacitor is charged by an intermediate circuit current that is supplied by a battery. The output voltage of the battery is settable to one or more voltage values. A target value of the intermediate circuit current is determined, and an actual value of the intermediate circuit current is ascertained. The actual value of the intermediate circuit current is then compared with the target value of the intermediate circuit current. An optimal output voltage of the battery is determined on the basis of the comparison of the actual value of the intermediate circuit current with the target value of the intermediate circuit current.
