A data driven model for accurate SOC estimation in EVs
2017 IEEE International Conference on Industrial Technology (ICIT), 2017Accurate state of charge (SOC) is critical for battery energy management system in electric vehicle (EV) application. Overcharge and over discharge will shorten battery's lifespan and induce potential safety problem, which may even permanently damage the lithium-ion battery.

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.

On the analytic accuracy of battery SOC, capacity and resistance estimation
2016 American Control Conference (ACC), 2016The Cramer-Rao bounds for battery state of charge, capacity and resistance estimation are derived in this paper. Independent of any specific form of observers, the bounds explore the quality of the data collected for estimation and indicate the best achievable accuracy of any (unbiased) estimator under measurement noise.
