State of charge estimation for electrical vehicle batteries

2008 IEEE International Conference on Control Applications, 2008
Lithium ion batteries play an increasingly important role as high-rate transient power sources for hybrid electric vehicles, cycling around a relatively fixed state of charge (SOC). A crucial step in enhancing the performance of these batteries is the estimation of the state of charge as a function of the load.

State of charge estimation and battery balancing control

2015 54th IEEE Conference on Decision and Control (CDC), 2015
In this paper, we propose an algorithm to solve the balancing problem of multi-cell battery systems consisting in the equalization of all cells state of charge (SoC). A nonlinear cell model is presented and experimental LiFePO4 battery cell parameters are used.

Performance Comparison of Nonlinear State Estimators for State-of-Charge Estimation of Supercapacitor

2021 IEEE Second International Conference on Control, Measurement and Instrumentation (CMI), 2021
Accurate state-of-Charge (SOC) estimation of supercapacitor is very crucial for real-time energy management and control of the energy storage device. This paper deals with performance comparison and analysis of the two most commonly used SOC estimators, namely Extended Kalman Filter (EKF) and Unscented Kalman Filter (UKF) for remaining charge ...

Adaptive state of charge (SOC) estimator for a battery

2006 American Control Conference, 2006
This work proposes an adaptive least-squares estimation strategy to determine the state of charge (SOC) for an electro-chemical battery. An estimation analysis is presented which proves that under a set of qualifying conditions, that the SOC of the battery can be estimated.

On battery State of Charge estimation: A new mixed algorithm

2008 IEEE International Conference on Control Applications, 2008
A new SoC estimation algorithm is presented. The estimation is performed mixing the Coulomb-Counting and the Model-Based estimation approaches. The algorithm was tested on a brand new lithium-ion cell which use a nanoscale technology able to grant a more powerful and safer lithium-ion battery than the batteries currently on the market. The cell, called

Combination Algorithm for State of Charge Estimation

2013 International Conference on Communication Systems and Network Technologies, 2013
When using the Ah counting method to estimate state of charge of battery on electric vehicle, it is difficult to measure the initial SOC, and will bring accumulated errors. In order to solve the above problem, we design an algorithm which integrates the open circuit voltage method (OCV), Kalman filter (KF) and Ah counting method (Ah) in this paper ...

Li-ion battery parameter estimation for state of charge

Proceedings of the 2011 American Control Conference, 2011
Battery state of charge (SOC) is a critical parameter for the control of propulsion systems in plug-in hybrid electric vehicles (PHEV) and electric vehicles (EV). As SOC is not measureable during vehicle operation, an onboard adaptive algorithm is developed in this paper.

A Robust Algorithm for State-of-Charge Estimation With Gain Optimization

IEEE Transactions on Industrial Informatics, 2017
The charging and discharging procedure of a battery is a typical electrochemical process, which can be modeled as a dynamic system. State of charge (SoC) is a commonly used measure to quantify the charge stored in the battery in relation to its full capacity. Recent efforts of optimizing battery performance require more accurate SoC information.

Robust state-of-charge estimation of ultracapacitors for electric vehicles

2015 IEEE 13th International Conference on Industrial Informatics (INDIN), 2015
Ultracapacitors (UCs) are an important energy storage technology in automotive and grid applications. They have several advantages, including high power density and extraordinarily long lifespan. Accurate State-of-Charge (SOC) tracking of UCs is critical for the reliability, resilience, and safety in system operation. This paper presents a novel robust
