“…The Coulomb counting method measures the discharge current from the battery and integrates it in relation to time with the objective of estimating the SoC [32]. This method is realized to estimate the SoC(t), which is an estimate from the discharge current I(t), and the forecast values for SoC (SoC (t − 1)).…”

“…s∈I(n) π ρ (s)Pr ρ (E 1 = e|E 0 = s) = π ρ (e), ∀e ∈ E, (steady-state equations) (9) (Note that in this case, π ρ is independent of the initial state E 0 = e 0 ).…”

“…An online SOC estimation algorithm based on controlled discharge is thus proposed and shown to perform well, albeit at a small energy loss. In [9], [10], different algorithms are designed for the estimation of the open circuit voltage of an electrochemical battery, which is linearly related to the SOC. The complexity of the algorithms signifies that SOC estimation for electrochemical batteries is not a trivial task, hence precise knowledge of the SOC may be unreliable or too expensive.…”

“…Chiasson et al [1] used an equivalent circuit model of a class of electrochemical batteries to perform SOC estimation via open circuit voltage (OCV) estimation. Dominico et al [2] used an averaged, first principle, electrochemical lithiumion battery model for SOC estimation using Extended Kalman Filter (EKF).…”

“…There are two main approaches to the modeling of lithium-ion batteries, the first principles model approach [2], and the equivalent circuit model approach [1]. While there are advantages in using first principles model for battery controls, due to limited capabilities of microcontrollers used in automotive control modules, an equivalent circuit model is used.…”
