Resumen de: EP4704334A1

The invention relates to a computer-implemented method (100) for calculating an efficiency degradation rate of an energy conversion device (50) from measurement data (10) of the energy conversion device (50). The method comprises the steps of: a) providing first measurement data (14) of a first observation obtained at a first time point, the first measurement data including multiple measurement data points each relating an energy input value of the energy conversion device (50) to an energy output value of the energy conversion device (50); b) applying a mathematical model to the first measurement data (14) to obtain a function modelling the first measurement data (14); c) determining (130) a first coefficient of conversion from the obtained function, wherein the first coefficient of conversion represents a ratio of the energy input to the energy output at the first time; d) repeating (140) steps a) to c) with second measurement data of the energy conversion device (50) obtained at a second time point, the second time point being different than the first time point, thereby obtaining a second coefficient of conversion representing a ratio of the energy input to the energy output at the second time point; e) comparing (150) the first coefficient of conversion with the second coefficient of conversion to determine the efficiency degradation rate of the energy conversion device (50).
