Estimation of State of Charge of Battery

2021 5th International Conference on Trends in Electronics and Informatics (ICOEI), 2021
Most common man would think Electric Vehicles are the future, but it is not, Electric Vehicles are here and as we push importance of green energy in the present world EVs are becoming the best choice for environment. And most important thing in Electric Vehicles is Battery Management System (BMS). Our proposed work is helpful in selecting more suitable

Battery state-of-charge estimation

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
This paper discusses the problem of lead acid battery state-of-charge estimation for (hybrid) electric vehicles. The problem is to accurately estimate the remaining battery capacity for both driver notification and automated energy management. The article presents a review of the problem, existing solution methods, presentation of a new solution method,

Estimating the state of charge of a battery

IEEE Transactions on Control Systems Technology, 2004
This brief considers the state of charge (SOC) estimation problem for electrochemical batteries. Using an electric circuit model of the battery given in the literature, it is shown how the open-circuit voltage (which is directly related to the SOC) can be estimated based on the terminal voltage and current measurements provided there is sufficient ...

State of charge estimator for NiMH batteries

Proceedings of the 41st IEEE Conference on Decision and Control, 2002., 2003
A state of charge estimator for Nickel-Metal Hydride batteries, suitable for hybrid vehicles automotive applications, is proposed. The estimator is based on a statespace dynamic model of the battery which is obtained by modeling the kinetic of reactions and the diffusion phenomena.

Battery equalization based on state of charge

The 2014 2nd International Conference on Systems and Informatics (ICSAI 2014), 2014
With the development and popularity of Lithium battery powered PEVs (Pure Electric Vehicles), BMS (Battery Management System) with equalization techniques become a key issue in high performance PEV design. This paper introduces a linear regression based real-time State of Charge calculation method through a second-order RC model of Lithium batteries ...

Gap states of charged solitons in polyacetylene

Physical Review B, 1989
Abstract : By considering the electron interactions in polyacetylene, it is found that there exist two gap states in charged solitons of trans- polyacetylene: one is deep level, and the other is shallow level. The deep one shifts 0.23 eV down (for a positive soliton) or up (for a negative soliton) from the center of the gap, while the shallow one is 0 ...

State of charge

IEEE Spectrum, 2012
In a cloud of car exhaust during a Friday rush hour, I'm humming over San Francisco's Golden Gate Bridge in an all-electric, tailpipe-free Nissan Leaf. I've plotted a course for Vacaville, 88 kilometers (55 miles) north, known for its sprawling outlet mall.

BATTERIES | Adaptive State-of-Charge Determination

2009
This article gives an overview of available state-of-charge (SoC)-indication methodologies and highlights many related practical implementation issues. First of all, a brief history of the developments in SoC indication is given. The lithium-ion battery technology is briefly discussed as illustration, because battery behavior needs to be understood and

Micro power battery state-of-charge monitor

IEEE Transactions on Consumer Electronics, 2008
This paper presents the design and implementation of a micro power battery state of charge monitor. The novelty of this design lies in the extreme low power consumption and accurate prediction of the battery reserve time. The average current drawn is successfully limited to 60 muA, which is significantly smaller than those in currently available ...
