The invention provides a battery management method and device and a battery management circuit, and the method comprises the steps that a battery management system comprises a plurality of battery management modules, and the battery management modules are connected in parallel, each battery management module executes the following steps: judging chip selection signals of a plurality of other battery management modules connected in parallel with the battery management module; if the chip selection signals are all the chip selection signals indicating the slave mode, calculating the time when the chip selection signals of a plurality of other battery management modules connected in parallel with the battery management module are all the chip selection signals indicating the slave mode; and if the time of the chip selection signals indicating the slave mode exceeds the preset mode holding time of the battery management module, the battery management module enters the host mode. And the host and the slave are independently selected from the plurality of battery management modules, so that the normal work of the battery management system is ensured.
本申请提供了一种电池管理方法、装置及电池管理电路,其中,该方法包括:所述电池管理系统包括多个电池管理模块,每个电池管理模块之间并联连接,其中,每个电池管理模块执行以下步骤:判断与该电池管理模块并联的多个其他电池管理模块的片选信号;若均为指示从机模式的片选信号,则计算与该电池管理模块并联的多个其他电池管理模块的片选信号均为指示从机模式的片选信号的时间;若均为指示从机模式的片选信号的时间超过该电池管理模块预设的模式保持时间,该电池管理模块进入主机模式。达到了在多个电池管理模块中自主选择主机从机,保证电池管理系统正常工作的效果。
