Equivalent Circuit Model for High-Power Lithium-Ion Batteries under High Current Rates, Wide Temperature Range, and Various State of Charges

open access: yesBatteries, 2023
The most employed technique to mimic the behavior of lithium-ion cells to monitor and control them is the equivalent circuit model (ECM). This modeling tool should be precise enough to ensure the system’s reliability.

Particle Size Effects on Dynamic Behavior of Heated Spheroidal Particles in Shear Flow

open access: yesChemical Engineering &Technology, Volume 49, Issue 3, March 2026.
Understanding the dynamics of nonspherical particles in shear‐driven flows is essential for a wide range of engineering applications. This study examines how confinement ratio, thermal effects, and interparticle interactions influence the migration, equilibrium positions, and rotation of nonspherical particles in such flows.

Trait‐based approaches to restoration ecology: Synthesizing insights from diverse systems

open access: yesEcological Applications, Volume 36, Issue 2, March 2026.
Abstract Under accelerating global change, trait‐based approaches are emerging as essential tools in the ecological restoration toolbox. Where restoration has traditionally focused on the recovery of focal species in isolated systems, trait‐based methods can provide a common language that extends beyond species‐ or system‐specific contexts, allowing ...

Optimized State‐of‐Health Estimation for Electric Vehicle Battery Under Operating Condition using Impedance and Resistance: A Robust Fusion Model

open access: yesEnergy Technology, Volume 14, Issue 3, March 2026.
This study proposes an state‐of‐health estimation algorithm that integrates electrical and electrochemical information through alternating current signal conversion and a probability density‐based fusion model. Results demonstrate that the fusion model achieves significantly higher accuracy across varying conditions, particularly under both room‐ and ...
