Transfer learning-based SOH estimation from partial charging data with polarization-aware modeling
Yuxia Li, Yuanyuan Gao, Xianbao Wang, C Wang, Zi Wang, Chuxiong Wu, et al.
Accurate state-of-health (SOH) estimation from incomplete charging data remains difficult when batteries are operated under variable charging protocols and when the prior polarization history is unknown. Many existing data-driven methods either rely on handcrafted health indicato…
