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.

    本发明公开了一种用于动力电池的均衡管理系统、方法及动力电池,包括电池管理模块和若干个电池监控模块;电池管理模块与各个电池监控模块之间通过无线通讯相连接;电池监控模块用于采集对应电池组的电池信息,并发送至电池管理模块,以及接收来自电池管理模块的均衡信息进行电池均衡,电池均衡包括单体电芯均衡和电池组均衡,电池组均衡包括调整无线通讯的通讯参数以实现电池组均衡;电池管理模块用于接收电池信息,判断是否开启电池均衡,生成均衡信息并下发至电池监控模块。本发明使电池单体的均衡开启不再依赖于电池管理模块的决策,并通过无线通讯模块参与电池组电量均衡,实现了采集与均衡的同时进行,实现了动力电池的全时均衡和高效均衡。
