A method is described for determining the charge state of a secondary intercalation cell having an anode, a cathode, a separator, and an electrolyte phase, which saturates the anode, the cathode, and the separator, in which the charge state is back-calculated on the basis of measured variables, which are measured on the intercalation cell, with the aid of an electrochemical simulation model. In the fundamental simulation model, physical-chemical properties in the anode and the cathode are each considered in simplified form as being homogeneously distributed in the anode and in the cathode and Butler-Volmer reaction kinetics are calculated in each case for the anode and for the cathode. The Butler-Volmer reaction kinetics are expanded on the anode side by a potential component (Φ2) in the electrolyte phase of the anode.
