Abstract
In order to analyze the dynamic behavior of a
Lithium-ion (Li-ion) battery and to determine their suitability
for various applications, battery models are needed. An
equivalent electrical circuit model is the most common way of
representing the behavior of a Li-ion battery. There are
different circuit models proposed and various techniques for
parameterization of these models available in literature.
Nevertheless, in this paper a second order equivalent circuit is proposed and the current pulse technique is used for its parameterization. This study shows results of extensive experimental characterization tests performed for a wide range of operating conditions (temperature, load current and state-ofcharge) on a commercial available 13Ah high-power lithium titanate oxide battery cell. The obtained results were used to parametrize the proposed dynamic model of the battery cell. To assess the accuracy of the proposed dynamic model, simulation results are presented and compared against laboratory measurements, performed for different conditions.
