A method for determining the state of charge of a storage battery, wherein at least two methods of different approach for determining state of charge are simultaneously applied. The individually obtained results of the different methods are weighted in accordance with their respective reliability in the respective current or former operating situation of the storage battery, and the weighted mean value of the individual methods thus obtained is used as final output variable of the method and displayed. The voltage of the storage battery, the current flowing through it and its temperatures are measured, and the different methods use these input variables and variables derived from these input variables as final input variables. At least one of the different methods uses the integration of the current flowing through the storage battery to determine the changes in the charge content of the storage battery. At least one other of the different methods uses a mathematical model which is implemented on an electronic computer and simulates the behavior of the storage battery.
