Abstract
Highlights Modelling provides requirements for impedance reconstruction via current interruption A Gaussian window must be introduced in Fourier transform to damp measurement noise Sampling at 70 μs for 40 s enables reconstruction at 1% accuracy within 10−1-103 Hz The technique may be integrated for on-line state-of-health evaluation of batteries
