EV Modeling and Battery SOC Estimation
Journal of Institute of Control, Robotics and Systems, 2018This 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

Chip size estimation for SOC design space exploration
Journal of Systems Architecture, 2006At early design space exploration phases of architectures for Systems On a Chip (SOC) chip size estimation is of high interest. An accurate chip size estimation needs detailed knowledge of the transistor densities of a semiconductor process. This paper introduces a novel and simplified chip size estimator, which is independent of manufacturer specific ...

Battery SOC and SOH Estimation
2019Battery SOC and SOH estimation are core functions performed by the BMS. Accurate SOC and SOH estimation can ensure the safe and reliable operation of the battery system, and provide the basis for energy management and safety management of EVs. However, batteries exhibit the characteristics of limited measurable parameters, coupling feature, degradation

Power-supply noise in SoCs: ATPG, estimation and control
IEEE International Conference on Test, 2005., 2006Noise 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.

Estimation of SOC of Battery Based on RVM-EKF Algorithm
2018 11th International Symposium on Computational Intelligence and Design (ISCID), 2018In order to improve the accuracy of SOC estimation, a new algorithm based on the relevance vector machine (RVM) and an extended Kalman filter (EKF) method (RVM-EKF) is proposed. An error prediction model was built based on RVM, by which the measurement noise covariance of EKF was realtime revised.
