EKF-based estimation of SOC and temperature in ultracapacitors

2013 10th IEEE International Conference on Control and Automation (ICCA), 2013
In this paper, simultaneous estimation of state-of-charge (SOC) and temperature is achieved by applying extended Kalman filter (EKF) algorithm with only the terminal measurement of voltage and current. For the application of EKF algorithm, a nonlinear model which consists of a voltageand-thermal-dependent equivalent circuit model and a thermal model is

A New SOC Estimation Algorithm

2018
The DE algorithm has strong global search ability and robustness, but also has the shortcoming of slow convergence speed and local search ability is insufficient, and TLBO algorithm has the advantage of strong local search ability and faster convergence speed, but will be fall into the local optimum when dealing with complex problems.

Overview of lithium-ion battery SOC estimation

2015 IEEE International Conference on Information and Automation, 2015
In this paper, different types of batteries are summarized which are used in electric vehicles. The performance of the battery, including material, duration, environment impact such factors can seriously restrain the development of renewable vehicles. Battery state-of-charge (SOC) plays an important role in vehicle driving regulation.

A Study on Estimation of SOC of Emus Batteries

2020 39th Chinese Control Conference (CCC), 2020
The on-board batteries of the Emus have extremely high accuracy requirements for real-time estimation of state of charge (SOC). The ordinary Ah integration method and the open-circuit voltage method cannot meet the actual requirements of the Emus. This paper estimates the battery SOC based on the extended Kalman filter (EKF) algorithm.

Design of EKF-based SoC estimator for an ultracapacitor module

IEEE EUROCON 2015 - International Conference on Computer as a Tool (EUROCON), 2015
This paper presents the design of ultracapacitor module state-of-charge (SoC) estimator based on an Extended Kalman Filter (EKF). A lumped-parameter resistive-capacitive (RC) electrical circuit representation of ultracapacitor module has been used for EKF design, wherein non-linear capacitance effects have been included through SoC-dependent ...

EV Modeling and Battery SOC Estimation

Journal of Institute of Control, Robotics and Systems, 2018
This paper describes an electric vehicle (EV) model using Matlab/Simulink software and compares the modeled performance with test data from an EV developed for actual use. To develop a 28 ㎾ EV using an induction motor, a gearbox with a 1 : 5.5 ratio is used in the powertrain. We utilized an 11.1 ㎾h battery pack that includes a battery management system

SOC and SOH estimation for Li-ion batteries based on an equivalent hydraulic model. Part I: SOC and surface concentration estimation [PDF]

2016 American Control Conference (ACC), 2016
Accurate state-of-charge (SOC) and state-of-health (SOH) estimation is critical to ensure a reliable battery-management system (BMS). This problem is addressed here by resorting to a grey box battery model based on the so-called equivalent hydraulic model (EHM). It allows taking into account in a simple way the difference between bulk concentration and

Hardware resource estimation for heterogeneous FPGA-based SoCs

Proceedings of the Symposium on Applied Computing, 2017
The increasing complexity of recent System-on-Chip (SoC) designs introduces new challenges for design space exploration tools. In addition to the time-to-market challenge, designers need to estimate rapidly and accurately both performance and area occupation of complex and diverse applications.

Power-supply noise in SoCs: ATPG, estimation and control

IEEE International Conference on Test, 2005., 2006
Noise on the power-supply lines has become a critical factor especially in low-voltage designs as excessive noise may cause intermittent functional error and eventually system failure. Having a realistic picture of the worst case noise throughout a chip is important as we can devise a remedy to alleviate the problem before it becomes too late.
