Various embodiments include a method for analyzing an electrode layer for a battery storage device in an electrode layer production facility. The method may include: acquiring an image comprising two pixels of the electrode layer, wherein a first pixel represents a first location of the electrode layer and a second pixel represents a second location of the electrode layer, wherein the first location and the second location are disposed adjacent to each other; determining a first value for a material property of the electrode layer at the first location based on the first pixel; determining a second value for the material property of the electrode layer at the second location based on the second pixel; comparing the first value and the second value and determining a comparison value; and determining characteristic properties of the electrode layer based on the comparison value.

Various embodiments of the teachings herein include methods and/or systems for operating a power system having a central control unit and two power system components. The method may include: determining a self-estimated value for each power system component based on a respective state value; providing the central control unit with a present maximum amount of power for each of the components; receiving a request for a demanded electrical power; ascertaining a distribution variable relating to the demanded power for each component based on the self-estimated values and the maximum amount of power output; and distributing a demanded electrical power to the power system components. The power system components comprise an energy generator unit, an energy consumer unit, or an energy storage unit.

Various embodiments include a method for ascertaining the residual value of a used battery. The method may include: feeding the battery to a test station; bringing it to a test temperature; stabilizing the temperature within less than 2 K; measuring a load cycles using a high-precision coulometry apparatus; carrying out measurement until fulfilment of a termination criterion; ascertaining a first and a second value for a discharging capacity using two different calculation rules, wherein calibration is handled differently in the two calculation rules; carrying out an optimization process; determining a residual value of the battery; and determining whether the used battery is to be employed for use in a static energy storage device.
