  "textContent": "A method and apparatus for correcting a 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), when a length of voltage data in the state data of the battery cell is greater than a first preset length and less than a second preset length, and a change value of the voltage data in the state data of the battery cell is greater than a preset change threshold, a first set of pending parameters of a predetermined near-steady-state battery model according to the state data of the battery cell; predicting (103), according to the first set of pending parameters, a second set of pending parameters of the predetermined near-steady-state battery model; calculating (104) an estimated steady-state OCV value according to the second set of pending parameters; and determining (104) a SOC correction value corresponding to the estimated steady-state OCV value by using a preset correspondence between steady-state OCVs and SOCs to correct current SOC. 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.",
