The invention discloses an equalization management system and method for a power battery and the power battery. The equalization management system comprises a battery management module and a plurality of battery monitoring modules, the battery management module is connected with each battery monitoring module through wireless communication; the battery monitoring module is used for collecting battery information of a corresponding battery pack, sending the battery information to the battery management module and receiving equalization information from the battery management module for battery equalization, the battery equalization comprises single cell equalization and battery pack equalization, and the battery pack equalization comprises adjustment of communication parameters of wireless communication to realize battery pack equalization; the battery management module is used for receiving the battery information, judging whether battery equalization is started or not, generating equalization information and issuing the equalization information to the battery monitoring module. According to the invention, the equalization starting of the single batteries does not depend on the decision of the battery management module any more, and participates in battery pack electric quantity equalization through the wireless communication module, so that acquisition and equalization are carried out at the same time, and full-time equalization and efficient equalization of the power batteries are realized.
