Battery management system

The invention provides a battery management system. A distributed cache structure is realized by setting a slave control module, a master control module and a stack control module of different levels; the slave control module arranged for the battery module can directly collect the data of the battery monomers; the slave control module and the master control module are each provided with a storage unit, so that the obtained data can be stored, meanwhile, the stored data are uploaded when the data are inquired, and therefore the master control module and the slave control module can support continuous data collection, and high density of the collected data is achieved. 本发明提出一种电池管理系统，通过设置不同层级的从控模块、主控模块以及堆控模块实现分布式缓存结构；针对电池模组设置的从控模块能够直接对电池单体的数据进行采集；从控模块与主控模块中均设置存储单元，使得能够将获取到的数据进行存储，同时，在被问询时将存储的数据进行上传，从而使得主控模块、从控模块能够支持持续的数据采集，实现了采集数据的高密度。
