Claim One:
1. Method for determination of characteristic variables for electrical states of an energy storage battery, having the following steps: a) Subdividing the electrolyte volume (v) of the energy storage battery into at least two electrolyte volume components (v i ) with associated electrolyte balancing areas (S i ); b) Defining of at least two electrode plate balancing areas (P k ) by subdividing the total resistance (R M ) of the electrode plates in the energy storage battery into resistance components (R k M ) for the defined electrode plate balancing areas (P k ), and the total energy storage capacity (K M ) of the electrode plates in the energy storage battery into energy storage capacity components (K k M ) for the defined electrode plate balancing areas (P k ); c) Determining of the electrolyte concentration (r i ) of the electrolyte volume components (v i ) for the defined electrolyte balancing areas (S i ); d) Determining of the amounts of charge (KE k M ) which are in each case held in the electrode plates in the electrode plate balancing areas (P k ); and e) Determining of at least one characteristic variable for associated electrical states of the energy storage battery by means of a mathematical model for describing an electrical equivalent circuit at least by means of the variables of the resistance components (R k M ), of the energy storage capacity components (K k M ), of the electrolyte concentration (r i ) and of the amounts of charge (KE k M ) held.
