The invention provides a battery equalization control method, a battery management system, an electronic device and a storage medium, and the method comprises the steps: determining a to-be-equalized battery cell monomer and to-be-equalized charge data according to the current charge data of each battery cell monomer in a battery pack, and carrying out the equalization of the to-be-equalized battery cell monomer based on the to-be-equalized charge data of each to-be-equalized battery cell monomer; determining a first equalization duration for starting an active equalization operation on the battery pack; then, on the basis of the current charge data of each to-be-balanced battery cell monomer and the current working condition of the battery pack, determining one of the to-be-balanced battery cell monomers as a target battery cell monomer and the residual charge and discharge duration of the target battery cell monomer; and finally, based on the equalization duration segmentation coefficient, according to the
