The user manual says to that HPPC data can be inputted into the parameter estimation tool to get an estimate for internal resistances\/capacitances, however the Battery Modeling course in the Ansys learning hub states that this is only accurate at one operating point. My main questions are:<\/p>\n<ul>\n<li>If we collect our HPPC data at various temperatures\/SOC&#8217;s, does Ansys create a lookup table for the different operating points? If so, how reliable are Ansys&#8217;s interpolations\/extrapolations of these operating points? Ideally, we&#8217;d have internal battery parameters as functions of SOC and temperature.<\/li>\n<li>I&#8217;ve noticed mention of a &#8220;state-space model&#8221; crafted from Electrochemical Impedance Spectroscopy data.
