| Popis: | In this paper, the use of binary sequences for electrochemical impedance spectroscopy (EIS) of battery cells is experimentally investigated by implementing them on a VLSI 1-bit current digital-to-analog converter. Two types of binary sequences are considered, i.e. sigma-delta modulated multisine sequences and maximum-length binary sequences. Their performance is evaluated using a low-complexity experimental setup. Results prove that the two types of sequences are capable of estimating the complex impedance of a battery in the frequency range of interest 1 Hz-200 Hz with an RMSE smaller than 5% with respect to a reference instrument. Both sequences are suitable for implementing online in-situ EIS monitoring, because they enable fast measurement and simple integration within the battery cell itself. |
