Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

In this research study, a Thevenin equivalent circuit model (ECM) has been proposed for the Lithium-ion polymer battery (LiPo). Modeling the LiPo battery is essential to estimate (state of charge) SOC in the battery management system (BMS). Three RC parallel networks’ parameters have been analytically found based on analyzing voltage relaxations after each applied current pulse. The coulomb counting algorithm is utilized for SOC estimation of the battery. The simulation results of terminal voltage under constant 2C current rate and pulsed current discharge are in good agreement with experimental data obtained.
