State of charge estimation and battery balancing control
2015 54th IEEE Conference on Decision and Control (CDC), 2015In 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.

Adaptive state of charge (SOC) estimator for a battery
2006 American Control Conference, 2006This 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.

Combination Algorithm for State of Charge Estimation
2013 International Conference on Communication Systems and Network Technologies, 2013When 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 ...

On battery State of Charge estimation: A new mixed algorithm
2008 IEEE International Conference on Control Applications, 2008A 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

Charge State Estimation for Tandem MassSpectrometry Proteomics
OMICS: A Journal of Integrative Biology, 2005High-throughput protein analysis by tandem mass spectrometry produces anywhere from thousands to millions of spectra that are being used for peptide and protein identifications. Though each spectrum corresponds only to one charged peptide (ion) state, repetitive database searches of multiple charge states are typically conducted since the resolution of

State and state of charge estimation for a latent heat storage
Control Engineering Practice, 2018Abstract A nonlinear state observer is designed for a thermal energy storage with solid/liquid phase change material (PCM). Using a physical 2D dynamic model, the observer reconstructs transient spatial temperature fields inside the storage and estimates the stored energy and the state of charge.

State of Charge Estimator Design for a Gas Charged Hydraulic Accumulator
Journal of Dynamic Systems, Measurement, and Control, 2015The gas charged hydraulic accumulators under consideration are used as energy storage devices in automotive hydraulic hybrid systems. The knowledge of the state of charge (SOC) is of utmost importance for an efficient energy management of the hybrid drive-train. Since the direct measurement of the SOC is difficult and costly, an SOC estimator design is

Li-ion battery parameter estimation for state of charge
Proceedings of the 2011 American Control Conference, 2011Battery 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.

Robust state-of-charge estimation of ultracapacitors for electric vehicles
2015 IEEE 13th International Conference on Industrial Informatics (INDIN), 2015Ultracapacitors (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
