abstract = {In order to meet the required power and energy demand of
battery‐powered applications, battery packs are
constructed from a multitude of battery cells. For safety
and control purposes, an accurate estimate of the
temperature of each battery cell is of vital importance.
Using electrochemical impedance spectroscopy (EIS), the
battery temperature can be inferred from the impedance.
However, performing EIS measurements simultaneously at the
same frequency on each cell in a battery pack introduces
crosstalk interference in surrounding cells, which may cause
EIS measurements in battery packs to be inaccurate. Also,
currents flowing through the pack interfere with impedance
measurements on the cell level. In this paper, we propose,
analyse, and validate a method for estimating the battery
temperature in a battery pack in the presence of these
disturbances. First, we extend an existing and effective
estimation framework for impedance‐based temperature
estimation towards estimating the temperature of each cell
in a pack in the presence of crosstalk and (dis)charge
currents. Second, the proposed method is analysed and
validated on a two‐cell battery pack, which is the first
step towards development of this method for a full‐size
battery pack. Monte Carlo simulations are used to find
suitable measurement settings that yield small estimation
errors and it is demonstrated experimentally that, over a
range of temperatures, the method yields an accuracy of
±1°C in terms of bias, in the presence of both
disturbances.},
