摘要：A method is described for ascertaining an internal resistance of an electrical
energy accumulator. For this purpose, an analog voltage signal and an analog currentsignal are subjected to an analog to digital conversion and subsequently to band-passfiltering in order to obtain filtered voltage values and filtered current values. These arethen checked with regard to different calculation prerequisites, whereupon a zero-phaseresistance is calculated. Then, the calculated zero-phase resistance is supplied as internalresistance
