Abstract
This disclosure provides a method and an apparatus for correcting a state of health of a battery, a battery management system, and a storage medium, and relates to the field of battery technologies. The method includes: determining whether a current voltage value of a battery cell is within a correction OCV section of the battery cell; if yes, using the current voltage value of the battery cell as a correction voltage value; and acquiring an SOC correction value, and correcting a state of health (SOH) of the battery cell. According to the method, the apparatus, the battery management system, and the storage medium in this disclosure, reliability of an SOH correction result is improved, thereby providing accurate estimation of the state of health of the battery, a prolonged service life of the battery, and better user experience.
