The invention discloses an equalization management system for a power battery, and particularly relates to the technical field of battery management, and the equalization management system comprises a data collection module, a battery pack operation analysis module, a battery pack abnormity analysis module, a wireless communication module, a battery cell equalization module, a battery pack equalization module and a battery management module. The battery management module is connected with the plurality of data collection modules through wireless communication, analyzes battery operation information, detects abnormal conditions and unbalance conditions, and triggers an equalization strategy of a battery cell or a battery pack to ensure efficient and safe operation of the battery pack; according to the method, a distributed equalization strategy and a centralized equalization strategy can be combined, more flexible and efficient equalization management can be provided for the system, dependence on central control is reduced, meanwhile, the flexibility and adaptability of the system are improved, key features are determined through technologies such as mutual information, subtle abnormal changes can be captured more sensitively, and the method is suitable for large-scale popularization and application. And the equalization strategy of each battery pack is individually set by dynamically adjusting the safety coefficient.

    本发明公开了一种用于动力电池的均衡管理系统,具体涉及电池管理技术领域,包括数据收集模块、电池组运行分析模块、电池组异常分析模块、无线通讯模块、电芯均衡模块、电池组均衡模块和电池管理模块。电池管理模块通过无线通讯连接多个数据收集模块,分析电池运行信息,检测异常情况和失衡情况,并分别触发电芯或电池组的均衡策略,确保电池组的高效、安全运行;本发明能够将分布式均衡策略与集中式均衡策略相结合,可以为系统提供更灵活和高效的均衡管理,减少了对中央控制的依赖,同时提高了系统的灵活性和适应性,使用互信息等技术确定关键特征,能够更敏感地捕捉到细微的异常变化,通过动态调整安全系数个性化地设定各电池组的均衡策略。
