abstract = {In order to guarantee safe and proper use of Lithium-ion
batteries during operation, an accurate estimate of the
(internal) battery temperature is of paramount importance.
Electrochemical impedance spectroscopy (EIS) can be used to
estimate the (internal) battery temperature and several
EIS-based temperature estimation methods have been proposed
in the literature. In this paper, we argue that all existing
EIS-based temperature estimation methods implicitly
distinguish two steps: experiment design and parameter
estimation. The former step consists of choosing the
excitation frequency (or frequencies) and the latter step
consists of estimating the battery temperature based on the
measured impedance resulting from the chosen excitation(s).
By distinguishing these steps and by performing Monte-Carlo
simulations, all existing estimation methods are compared in
terms of accuracy (mean-square error) of the temperature
estimate. The results of the comparison show that, due to
different choices in the two steps, significant differences
in accuracy of the temperature estimate exist. More
importantly, by jointly selecting the parameters of the
experiment-design and parameter-estimation step, a more
accurate temperature estimate can be obtained. This novel
more-accurate method estimates the temperature with an rms
bias of 0.4°C and an average standard deviation of 0.7° C
using a single impedance measurement for the battery under
consideration.},
