      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.},
