Battery cell design must balance energy density, fast charging, and degradation, yet these metrics evolve over different time scales and are costly to optimize jointly. We develop a timescale-aware surrogate-assisted framework that evaluates beginning-of-life volumetric energy density and 10--80% charging time together...

A ranked-prefix feasible-set restriction is proposed for real-time mixed-integer model predictive control of series-connected reconfigurable battery packs with per-cell bypass switching. Cells are ordered at each sampling instant by a one-step objective-informed suitability score, and the engagement variables are const...

Enhancing utilization rates of battery systems in electric vehicles (EVs) substantially benefits economic efficiency and environmental sustainability. However, cell-to-cell inconsistency remains a critical barrier to fully realizing these advantages, and its system-level impact under real-world EV operation is still...
