N2 - State of health (SOH) estimation is critical for the lithium-ion battery health management. In this paper, a new set of health indicators (HIs) based on partial constant-current charging are extracted by scrutinizing the correlation against the SOH and the robustness to uncertainty of practical disturbance. A multiple linear regression model with an activation function is further established to construct the relationship between the extracted HIs and the battery capacity. Results give sufficient evidence for the low requirement on the charging integrity, the sufficient adaptability to the practical disturbances and the high robustness to cell inconsistency of the proposed method.
