Abstract
The invention relates to a method for determining the state of charge and loading capacity of an electrical storage battery by measuring current, voltage and temperature and comparing the measured values with the corresponding values for the response of an equivalent circuit diagram of the storage battery, the parameters of the components in the equivalent circuit diagram and the state variables being varied such that the measured values are matched and that the state of charge and loading capacity are determined from the adjusted parameters and state variables determined.
