A Novel Discharge Mode Identification Method for Series-Connected Battery Pack Online State-of-Charge Estimation Over A Wide Life Scale

Shiqi Liu et al.

Summary: This article proposes a new discharge mode identification (DMI) method for online SOC estimation of series-connected battery packs, which simplifies the process of searching for poorly performing cells by analyzing inconsistencies. The pack SOC is estimated based on the average or all cells during different discharge phases. Furthermore, a segmented coulomb counting (SCC) method based on partial adaptive forgetting factors recursive least square (PAFFRLS) is introduced to address the computational load issue in a battery management system (BMS).
