METHOD AND APPARATUS FOR CORRECTING SOC, BATTERY MANAGEMENT SYSTEM AND STORAGE MEDIUM

A method and apparatus for correcting a state of charge (SOC), a battery management system and a storage medium are provided. The method includes: acquiring (101) state data of a battery cell in a case where the battery cell meets a preset standing condition; determining (102), according to the state data of the battery cell, a near-steady-state battery model for characterizing a change in an open circuit voltage (OCV) over time in a near-steady-state and a steady-state time period threshold for characterizing whether a standing time period is sufficient; processing (103) the steady-state time period threshold by using the near-steady-state battery model to obtain an estimated steady-state OCV value; determining (104) a SOC corresponding to the estimated steady-state OCV value by using a preset correspondence between steady-state OCVs and SOCs; and correcting (105) a current SOC by using the SOC corresponding to the estimated steady-state OCV value. With embodiments of the disclosure, a steady-state OCV of a battery can be quickly estimated by using characteristics of an external circuit during a short standing time period of the battery, and applicability of an open-circuit voltage method can be improved.
