Procedure for the computer-aided determination of the parameters of an electrochemical energy accumulator

摘要

Provided is a method for determining parameters of an electrochemical energy store in a computer-aided manner, wherein a plurality of temporally successive measurement data records having respective assigned measurement times and a predefined model of the energy store are processed. A particular measurement data record includes a measured voltage value of a terminal voltage of the energy store, a measured current value of a current flow in the form of a charging or discharging current of the energy store and a state of charge measured value of the state of charge of the energy store Equation parameters of at least one linear equation system are stipulated in the method, which equation system is based on the predefined model.
