  • Method and system for ascertaining operating parameters of an electrochemical storage battery
    Patent number: 8080990
    Abstract: A method for ascertaining operating parameters of an electrochemical storage battery, taking into account electrolyte stratification. The method including a) determining a first functional relationship between no-load voltage and state of charge as a value for the withdrawable charge in relation to nominal capacity of the storage battery, which is obtained in the state having electrolyte stratification in a discharge phase using the charge conversion since a prior no-load phase or pre-charge; b) determining a second functional relationship between no-load voltage and state of charge as a value for the withdrawable charge in relation to nominal capacity of the storage battery, obtained in the state having electrolyte stratification in a discharge phase using an accumulated charge conversion; and c) ascertaining operating parameters from the point of intersection of the first and second functional relationships and/or the slope of straight lines for describing the first and/or second functional relationships.
