abstract = {An accurate estimation of the residual energy, i. e.,
State of Energy (SoE), for lithium-ion batteries is crucial
for battery diagnostics since it relates to the remaining
driving range of battery electric vehicles. Unlike the State
of Charge, which solely reflects the charge, the SoE can
feasibly estimate residual energy. The existing literature
predominantly focuses on showcasing diverse methods with a
gap in conducting in-depth analysis and comparison of the
SoE. The scope of this work is to provide a comprehensive
understanding of the SoE by discussing the feasibility and
applicability of various definitions and estimation
approaches from the literature. For the first time, we
classify existing SoE definitions, considering the
differences between the inherent stored and usable energy.
In the absence of a unified definition in the literature, we
propose two physically feasible definitions. Based on the
proposed definitions, we critically analyze the practical
challenges of SoE estimation. Additionally, to examine the
accuracy of the most suitable SoE definition, we conduct an
experimental evaluation using a commercial NCA/C+Si cell.
Compared to the State of stored Energy, we demonstrate that
the State of Charge underestimates the residual energy by
more than $3 \%,$ highlighting the importance of adequate
SoE estimation.},
