An Improved Equivalent Circuit Model and a Variable Scale Unscented Kalman Filter for State‐of‐Charge Estimation of Lithium‐Ion Batteries at Variable Ambient Temperatures

Y. B. Li, Yitao Shen, S.J. Chen, Zheyu Wang et autres

State of charge (SOC) is a key index of lithium‐ion batteries, and the equivalent circuit model is widely used in engineering to estimate the SOC of batteries, but its estimation accuracy is poor under complex dynamic conditions. To solve this problem, an …

Principle and Analysis of Structure of Low-Speed High-Torque Gear Meshing Motor Driven by Radial Force

Guodong Yu, Shuqi Sun, Y. B. Li, Yongxiang Xu et autres

This paper proposes a new motor structure based on the electromagnetic radial force drive. The radial electromagnetic force is converted into output torque through the meshing action of the gear pair, thereby significantly improving the torque density. In this study, the magnetic …

Dynamic Responses of Composite Marine Propeller in Spatially Wake

Y. Hong, Xiaoshu He, R. G. Wang, Y. B. Li et autres

Dynamic responses of a composite marine propeller in spatially wake were investigated in this paper. A hydroelastic model was developed to identify the response characteristics of the composite propeller blades using a finite element method (FEM) coupled with a computational fluid dynamics …

Anomalous capacitance-voltage characteristics of Al/Al-rich Al2O3/p-Si capacitors and their reconstruction

Zhaoqin Liu, T. P. Chen, Yi Liu, Ming Chi Yang et autres

Anomalous capacitance-voltage (C-V) characteristics of Al/Al-rich Al2O3/p-Si capacitors have been observed. The measured C-V curves exhibit rolloffs and frequency dispersion in the accumulation region and voltage stresses cause both horizontal and vertical shifts of the C-V curves. These anomalous behaviors are mainly …

Light-induced instability in current conduction of aluminum nitride thin films embedded with Al nanocrystals

Zhaoqin Liu, T. P. Chen, Yong Liu, Lu Ding et autres

Al nanocrystals (nc-Al) embedded in AlN thin films have been synthesized by rf magnetron sputtering. The influence of ultraviolet (UV) illumination on electrical characteristics of the nc-Al∕AlN thin film system has been investigated. It is shown that the UV illumination could lead …
