Current estimation using Thevenin battery model
Proceedings of the Joint International Conference on Electric Vehicular Technology and Industrial, Mechanical, Electrical and Chemical Engineering (ICEVT & IMECE), 2015 Current sensor is an important part of Battery Management System (BMS). Current information of a battery is very important to estimate the value of State of Charge (SOC) as a component of fault detection. Fault detection is very important to implement in BMS because of its function to protect battery from damage caused by over discharge and overcharge.

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

Accurate Method for Calculating the Effective Capacitance with RC Loads Based on the Thevenin Model
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2009In deep submicron designs, predicting gate delays with interconnect load is a noteworthy work for Static Timing Analysis (STA). The effective capacitance Ceff concept and the Thevenin model that replaces the gate with a linear resistor and a voltage source are usually used to calculate the delay of gate with interconnect load.

Osculating Thevenin model for predicting delay and slew of capacitively characterized cells
Proceedings 2002 Design Automation Conference (IEEE Cat. No.02CH37324), 2002 To extrapolate from one point to another using a line, one had better get the slope right. In this paper we apply a similar concept to the important problem in Static Timing Analysis (STA) of predicting cell timing for RC loads using capacitive characterization data.

Modeling of voltage source converters in microgrids using equivalent thevenin circuit
2018 9th Annual Power Electronics, Drives Systems and Technologies Conference (PEDSTC), 2018 In this paper, a new modelling approach based on the equivalent Thevenin circuit is proposed for voltage source converters in islanded microgrids. The proposed method approximate the entire network connected to the voltage source converter with an equivalent Thevenin circuit. The equivalent circuit is first considered with a non-dynamic impedance. This
