Enhancing Q‐Learning via State‐Space Design for Active Battery Balancing

open access: yesBattery Energy, Volume 5, Issue 2, March 2026.
This study investigates the profound impact of state definition on the efficacy of Q‐learning for active battery balancing in lithium‐ion battery packs. We define and evaluate three distinct state representations—[State 1, 11‐state space definition], [State 2, 27‐state space definition], and [State 3, 81‐state space definition]—within a reinforcement ...
