The invention relates to the technical field of batteries, and discloses a double-branch power battery control system and method. A battery management module judges voltage data and current data acquired by an acquisition module to judge whether a current branch breaks down or not; further a cathode contactor of one branch or the cathode contactors of two branches are selected to be closed so as to enable a corresponding battery pack to work or be disconnected; and when one branch breaks down and can not work, the other branch can independently provide a reliable energy source for the whole vehicle. A problem that the whole vehicle is broken down due to power battery faults can be avoided.

    本发明涉及电池技术领域,公开一种双支路动力电池控制系统及方法,电池管理模块对采集模块采集到的电压数据以及电流数据进行判断,以判断当前支路是否出现故障,进而选择闭合其中一个支路的负极接触器或闭合两个支路的负极接触器,从而控制相应的电池组工作或者断开,当一个是出现故障无法工作时,另一条支路可以独立的为整车提供可靠的能量来源,能够避免动力电池故障而出现的整车抛锚的问题。
