Battery Impedance Measurement by Laplace Transformation of Charge or Discharge Current/Voltage

Abstract: Impedance spectroscopy of Z(ω) is often used in the electrochemical field to analyze electrode reactions and to calculate transient responses. Our previous study measured the overpotential resistance for our thermal behavior model to calculate the temperature rise of Nickel/metal-hydride battery or Lithium-ion battery during charge and discharge cycles. However, the Z(ω) measured by AC impedance meter did not agreed with the ones induced by charge/discharge characteristics. Therefore, we focus on the impedance… Show more

“…20,21 And some singlechip impedance measurement systems are also designed. 22 For the impedance calculation methods, Fourier transform, 19 Laplace transform, 23 cross-correlation, 24 and Wavelet transform 25,26 are also widely studied. These provide a basis for the onboard application of impedance.…”

“…As it was aforementioned, in order to measure the impedance of a system, other signals than sinusoidal can be considered [67]. Many other studies in which impedance spectra was obtained from other signals rather than sinusoidal can be found [61][62][63][68][69][70].…”
