Abstract
A method for prediction of electrical characteristics of an electrochemical storage battery and includes determining a functional relationship between a state of charge value which is related to a first parameter for a storage battery and a second state of charge value which is related to a second parameter for the storage battery for a second phase of use of the storage battery. The method also includes determining at least one characteristic variable from the reference of the functional relationship for the second phase to a state characteristic variable profile for a previous first phase of use of the storage battery. The method further includes predicting electrical characteristics of the storage battery utilizing a functional relationship between the characteristic variable and the electrical characteristics.
