Fig. 3: Extraction of candidate features from the complete V-Q curve.

11 segments divided by various voltage intervals (a). (b), (c) convey the performance of each candidate feature in terms of charging time and initial SOC (state of charge). (d) depicts the variation trend of each candidate feature. The gradient in (a) corresponds to changes in battery SOH (state of health).
