METHOD OF DETERMINING FREQUENCY CHARACTERISTICS OF BATTERY TYPE SUPPLY SOURCES

摘要

FIELD: electrical engineering. SUBSTANCE: nonsinusoidal voltages applied to battery and battery current are recorded and expanded into harmonic F-series, and by values of amplitudes and initial phases of voltage and current harmonics, complex impedance of battery for each harmonic are determined and also their resistive and reactive components. By frequency characteristics of chemical supply source one can judge serviceability of supply sources, their condition, state of charge and carry out automatic control of charging process. EFFECT: increased accuracy of checking of amplitude-frequency and phase-frequency characteristics of all types of storage batteries within wide frequency.
