State of Charge Estimation of EV Secondary Battery Pack Using Hybrid Hedge Feedforward Feedback‐Based Gated Recurrent Unit to Extend Lifespan

open access: yesBattery Energy, Volume 5, Issue 2, March 2026.
SOC estimation is performed using a newly developed online HFF‐GRU method. Improves charge balancing among battery cells, leading to a substantial increase in the battery pack's lifespan. ABSTRACT Accurate estimation of state of charge (SoC) and maintaining balanced charge levels across secondary battery cells are crucial in battery management systems (

First Observation of Banded Electron Cyclotron Harmonic Waves at Earth's Magnetopause

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract This letter presents the first observation of banded Electron Cyclotron Harmonic (ECH) waves by Magnetospheric Multiscale (MMS) satellites near the Earth's subsolar magnetopause. The observation shows the fundamental mode (n=1 $n=1$) and its higher harmonics (n=2 $n=2$–6), each with distinct lower and upper bands separated by a spectral gap at
