Abstract
This paper describes the comparison and parameterization
process of dynamic battery models for cell and system simulation.
Three commonly used equivalent circuit battery models
are parameterized using a numeric optimization method and basic
electrical tests with a lithium-ion polymer battery cell. The maximum
model performance is investigated, and the parameterized
models are compared regarding the parameterization effort and
the model accuracy. For the model with the best tradeoff between
the parametrization effort and the model accuracy, a reasonable
simplification of the parameterization process is presented. This
model is parameterized with the simplified parameterization process
and, finally, validated by using a current profile obtained from
an electric vehicle simulation performing a real-life driving cycle.
