Abstract :
This paper provides a method and a system based on current pulse excitation and frequency spectrum analysis, which can complete battery impedance spectrum test and analysis. By exerting current excitation onto the battery, synchronously measuring current excitation and terminal voltage response, we count the amplitude spectrum and phase spectrum for current excitation and terminal voltage response under different frequencies. Also, we count the battery impedance under different frequencies according to spectrums of I and U, to get the complete spectrogram for the battery impedance. The technology provides a new solution for calculating and predicting the charge state and health state of the storage battery.
