A virtual-component-embedded equivalent circuit model for lithium-ion battery state estimation

International Journal of Electrical Power & Energy Systems
Accurate modeling of batteries is the preconditon for Battery Management Systems. However, under conditions such as battery aging, low temperatures and volatile charge/discharge cycles, Equivalent Circuit Model (ECM) tends to generate significant ...

Equivalent circuit modeling of a superconducting synchronous generator

Electrical Engineering in Japan, 1977
A method is proposed for deriving the equivalent circuit of a superconducting synchronous generator of coreless structure. In deriving the equivalent circuit, account was taken of the nonlinearity of the electromagnetic shield. Linear constants of this equivalent circuit can be calculated directly using design data, and nonlinear constants are ...

Single Solid‐State Ion Channels as Potentiometric Nanosensors

Advanced Functional Materials, EarlyView.
Single gold nanopores functionalized with mixed self‐assembled monolayers act as solid‐state ion channels for direct, selective potentiometric sensing of inorganic ions (Ag⁺). The design overcomes key miniaturization barriers of conventional ion‐selective electrodes by combining low resistivity with suppressed loss of active components, enabling robust

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications

Advanced Functional Materials, EarlyView.
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...
