Abstract
A method for correcting a SOH, an apparatus, a battery management system and a storage medium are provided. The method includes obtaining a relationship curve between a ratio of an accumulated charge/discharge capacity variation and a corresponding voltage-parameter variation of a battery cell and a voltage parameter itself; determining a valid peak point on the relationship curve; determining a SOH calibration value corresponding to voltage parameter datum at the valid peak point; correcting a current SOH according to the SOH calibration value. The estimation accuracy of the SOH can be improved according to this method.
