Modeling and SOC estimation of LiFePO4 battery

2016 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2016
In order to estimate the state of charge (SOC) of LiFePO4 battery more accurately, an improved Extended Kalman Filter (EFK) algorithm is proposed to estimate the parameters in the least squared identification model. A second-order RC equivalent circuit is used as the battery model, and an additive term is introduced into the state equation for real ...

High frequency jitter estimator for SoCs

2015 20th IEEE European Test Symposium (ETS), 2015
This paper presents an Embedded Test Instrument (ETI) for the estimation of the High Frequency (HF) jitter of an observed clock signal. The ETI uses a second reference clock for under-sampling the observed signal similar to previous approaches. However, the analysis of the test response does not require the construction of the Cumulative Distributed ...

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
