Abstract: Described herein are methods and systems for updating SOC estimates of individual cells in battery packs. Specifically, SOC estimates are updated in-situ, e.g., while the battery packs remain operational. For example, a cell is charged or discharged, independently from other cells, until the cell OCV is at a set value, corresponding to one of target zones. The target zones have more prominent correlations between the OCV and SOC than other parts of the OCV profile. A new SOC value, corresponding to the cell OCV, is used to update the SOC estimate. In some examples, a set of voltages is obtained while the cell is charged or discharged at a constant current/power, e.g., outside of the target zones. One or more differential capacities are determined from this voltage set, and a new SOC value is obtained based on these differential capacities.
