Method for prediction of electrical characteristics of an electrochemical storage battery

A method for prediction of electrical characteristics of an electrochemical storage battery, the method comprising:

• determining a functional relationship between a first 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;
• determining at least one characteristic variable using the functional relationship for the second phase and a functional relationship for a previous first phase of use of the storage battery;
• predicting electrical characteristics of the storage battery utilizing the characteristic variable;
• and
• determining an amount of charge which can be drawn in an instantaneous state from the difference between a state of charge value and the characteristic variable as the value of the state of charge value which is related to the second parameter from the functional relationship with the state of charge value which is related to the first parameter and is equal to zero, and with the difference multiplied by the battery capacity representing the amount of charge which can still be drawn in the instantaneous state.
