  • Abstract
    This work is devoted to impedance measurements in the frequency band corresponding to the Randles model of the first order. There was proposed the estimating technique of the battery SOC based on the Bode phase diagram. The frequency of the local minimum on the impedance phase characteristic makes it possible to assess the loss of the battery capacity at early stages of life. The proposed experimental setup may serve as a prototype for impedance testers in the field.
