Abstract
A method for determining the operating state of an energy-storage battery in assumed temperature and state of charge conditions, which has the following steps: a) measurement of a temperature variable (T.sub.ACT) which is correlated with the battery temperature (T.sub.BAT), b) determination of the state of charge (SOC.sub.ACT) of the energy-storage battery, c) determination of a further state variable (A.sub.ACT) of the energy-storage battery, d) formation of a reference value (B.sub.V) from the reference between the determined state variable (A.sub.ACT) and a corresponding state variable (A.sub.NEW) of an identical, new energy-storage battery with the same temperature variable (T.sub.ACT) and the same state of charge (SOC.sub.ACT), and e) determination of a predicted state variable (A.sub.P) as a measure of the operating state for an assumed temperature variable (T.sub.P) and an assumed state of charge (SOC.sub.P) from known comparison reference values (B.sub.T), which have been recorded as a function of temperature variables (T), states of charge (SOC) and the aging state of identical energy-storage batteries.
