Abstract

A method for determining a state of charge (SOC) characteristic variable for a storage battery including determining a first SOC value and a second SOC value. The method further including determining changes in the first and second SOC values. These changes in the first and second SOC values are measured between a first operating time and a second operating time. The method also including determining a characteristic variable relating to the state of charge as a function of the change in the first and second SOC values.
