SOC Estimation of Lithium-Ion Battery Packs Based on Thevenin Model

open access: yesApplied Mechanics and Materials, 2013
Due to the immeasurability of SOC in battery and inevitability of error in current collection, SOC estimation of Lithium-ion battery has become a focus of EV research. With Thevenin equivalent circuit model, this paper employs EKF algorithm to estimate SOC, which takes into consideration both precision requirement of the estimation and amount of ...

A Parameter Extraction Method for the Thevenin Equivalent Circuit Model of Li-ion Batteries

open access: yes2019 IEEE Industry Applications Society Annual Meeting, 2019
This paper presents a novel parameter extraction method for the Thevenin equivalent circuit model of Lithium-ion batteries. The proposed approach represents each of the RC parallel branches of the Thevenin equivalent circuit model of a Lithium-ion battery as a first order linear time-invariant (LTI) system.

A Dynamic Model of Impedance for Online Thevenin’s Equivalent Estimation

IEEE Transactions on Circuits and Systems II: Express Briefs, 2022
A time domain dynamic model of impedance has been developed in this work for online estimation of Thevenin’s equivalent impedance of a network seen from a bus. Although the time domain impedance (ratio of instantaneous AC voltage and current) is undefined in a period, a zone of definition and workability has been defined.
