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

A Robust Algorithm for State-of-Charge Estimation With Gain Optimization
IEEE Transactions on Industrial Informatics, 2017The 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.

State-of-charge estimation for supercapacitors: A Kalman filtering formulation
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014Supercapacitors are an attractive option for energy buffering because of their high efficiency, durability, and low environmental impact. For energy-aware applications, it is desirable to accurately estimate the buffered energy. Under conditions of varying energy supply and demand, estimation of buffered energy by using only the supercapacitor terminal

On-line battery state-of-charge estimation based on an integrated estimator
Applied Energy, 2017Energy crises and environmental issues have promoted research into development of various types of electric vehicles (EVs). Since the control strategy of EVs is essentially dependent on the state-of-charge (SoC) estimation of the batteries, one of the most critical issues of battery management system (BMS) is to accurately estimate the SOC in real-time.

Quantum neural network for State of Charge estimation
2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE), 2014State of Charge (SoC) estimation is one of the most important parts of Battery Management System (BMS). Inaccurate estimation of SoC may cause overcharge or overdischarge which could lead permanent damage to battery cells. Neural Network (NN) models can yield quite accurate SoC estimation. However, the computation effort is also quite huge and it takes
