A battery management system and an addressing method, which relate to the technical field of battery management. The system comprises a master management module (110) and slave management modules (120), wherein the master management module (110) is used for obtaining the total voltage of batteries (130) managed by the slave management modules (120), for sending an addressing pulse signal to a first slave management module (120) by means of a control signal output interface (123) thereof, for receiving a battery voltage fed back by at least one slave management module (120) by means of a communication interface (112, 122) thereof, and for sending, by means of the communication interface thereof, an instruction for continuing to perform addressing to the slave management module (120) that feeds back the battery voltage after determining, according to the total voltage and the battery voltage fed back, to continue to address the slave management module (120); and each slave manag ement module (120) is used for receiving the addressing pulse signal, for setting an addressing address after level switching occurs on the addressing pulse signal, and for feeding back the voltage of the battery (130) managed by the slave management module to the master management module (110) by means of the communication interface (112, 122) thereof. By means of the solution provided by the system for addressing, the addressing efficiency can be improved.
一种电池管理系统及编址方法,涉及电池管理技术领域,上述系统包括:主管理模块(110)和从管理模块(120);主管理模块(110),用于获得各从管理模块(120)所管理电池(130)的总电压,通过其控制信号输出接口(123)向第一个从管理模块(120)发送编址脉冲信号;接收至少一个从管理模块(120)通过其通信接口(112,122)反馈的电池电压,在根据总电压和反馈的电池电压确定继续对从管理模块(120)编址后,通过其通信接口向反馈电池电压的从管理模块(120)发送继续编址指令;各个从管理模块(120),用于接收编址脉冲信号,在编址脉冲信号发生电平切换后,设置编址地址,并通过其通信接口(112,122)将其所管理电池(130)的电压反馈至所述主管理模块(110)。应用该系统提供的方案编址,能够提高编址效率。
