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 ...

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

Dual-sliding-mode observer for SOC estimations

2017 IEEE Southern Power Electronics Conference (SPEC), 2017
A sliding mode-based observer is proposed in order to estimate the state-of-charge (SOC) of a Li-ion battery. The proposed observer is designed based on high-order sliding modes attaining a low level of chattering, which becomes quite attractive. The battery's state estimation is made through a charge/discharge cycle, calculating the model's parameters.
