TL;DR: In this article, a nonlinear mapping process is involved to recursively calculate the system state variable, thus the errors caused by Extended Kalman Filter (EKF) can be effectively restrained; besides, compared with many simple battery models recently, the comprehensive model presented in this paper can track the operating performance of valve regulated lead acid (VRLA) battery more correctly.

TL;DR: In this article, the authors investigated the relationship between the state-of-charge (SOC) and the dynamically changed open-circuit voltage of lead-acid batteries, and proposed a dynamic open circuit voltage method by taking account of the open circuit time and the previous charging/discharging rate.
Abstract: The charging and discharging characteristics of lead-acid batteries are investigated to learn the relationship between the state-of-charge (SOC) and the dynamically changed open-circuit voltage Experimental results indicate that the open-circuit voltage of the lead-acid battery varies methodically with the charging or discharging rates and the duration since they have been disconnected from the load or charger Accordingly, a dynamic open-circuit voltage method by taking account of the open-circuit time and the previous charging/discharging rate is capable of more precisely estimating the SOC in a shorter time Experiments that emulate practical operations are carried out to demonstrate the effectiveness and accuracy of the proposed method
