Abstract | SoH (State-of-Health) evaluation is of pressing need in the health management of commercial Li-ion batteries and has been a topic of intensive research. A simple route to supply a quick, non-destructive, and preferably on-site assessment of SoH with high fidelity is desired. In this paper, analysis based on a partial (dis)charge and a sliding voltage window on the constant-current (dis)charge voltage-time curve may fulfill the need. The incremental State-of-Charge (Delta SoC) (derived from the sliding window) is proportional to the SoH within a suitable voltage region. The slope k of the SoH - Delta SoC curve and its extrapolated interception at SoH=1, denoted as Delta S1oC, can then be used to differentiate the remaining life of batteries of the same SoH. The proposed SoH evaluation method, along with the linearity characterized by k and Delta S1oC, make it an appealing route toward quick and on-site health management of batteries. |
