RFSR-MI-MPC: Ranking-Based Feasible-Set Restriction for Real-Time Control of Reconfigurable Battery Packs
Albert Škegro, Quan Ouyang, Torsten Wik +1
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 swit…
Reducing Combinatorial Redundancy in Mixed-Integer MPC via Ranking-Based Feasible-Set Restriction for Reconfigurable Batteries
Albert Škegro, Torsten Wik, Changfu Zou
When mixed-integer model predictive control must select which of several similar units to activate, many same-size selections can yield closely spaced predicted outcomes, and branc…
Timescale-aware surrogate-assisted multi-objective optimization of battery cell design for energy density, fast charging, and degradation
Qingbo Zhu, Changfu Zou, Yicun Huang +2
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…
