Claim 0:
1. A control unit for an energy accumulator, comprising:
the control unit, wherein the control unit is configured to:
detect, during operation of the energy accumulator, event data relating to different discharging/charging events of the energy accumulator, wherein the event data for a discharging/charging event indicate an event discharge depth of the energy accumulator in the context of the discharging/charging event;
determine a discharge depth distribution on the basis of discharge data that, for different discharge depths, indicates a number of discharging/charging events having a corresponding event discharge depth during the operation of the energy accumulator;
determine state data relating to a cumulative loading of the energy accumulator on the basis of the discharge depth distribution and on the basis of a discharge depth characteristic curve of the energy accumulator, and/or adapt an operating strategy for the energy accumulator depending on the discharge depth distribution and the discharge depth characteristic curve;

determine a first discharge depth distribution at a first time point of the operation of the energy accumulator;
determine a second discharge depth distribution at a subsequent second time point of the energy accumulator;
predict a predicted discharge depth distribution for a future time point on the basis of the first discharge depth distribution and the second discharge depth distribution; and
determine the state data on the basis of the predicted discharge depth distribution and/or adapt the operating strategy of the energy accumulator on the basis of the predicted discharge depth distribution.
