Abstract :
This paper is devoted to impedance measurements over the frequency band corresponding to the Randles model of the first order. An estimation technique is proposed to assess the state of charge of a battery using a developed experimental system. Randles parameter identification is carried out based on frequency response. This paper focuses on the analysis of the propagated uncertainty of input variables determining the measurement accuracy of battery parameters.
