The present disclosure relates to the field of battery technologies, and more particularly, to a method and apparatus for equalizing a battery pack, a vehicle, and a storage medium. The method includes: determining whether a current battery pack meets a predetermined offline equalization condition; determining, in response to the current battery pack meeting the predetermined offline equalization condition, a target cell to be equalized in the current battery pack, an equalization time length of the target cell, and a periodic wake-up duration; and equalizing the target cell based on the equalization time length of the target cell, controlling a battery management system to enter a sleep mode, obtaining a duration for which the battery management system is in the sleep mode, waking up the battery management system in response to the duration reaching the periodic wake-up duration, and re-determining whether the current battery pack meets the predetermined offline equalization condition. Therefore, problems in the related art that the target cell that needs to be equalized fails to be accurately determined and a balance between a consistency among battery cells and high energy of the vehicle cannot be maintained are solved, making the equalization target more accurately determined.
