According to the daisy chain reverse wake-up method, the battery management system and the battery management equipment provided by the invention, when the main control unit is in the dormant state, each front-end unit monitors the communication state of the corresponding battery pack and the daisy chain, and if a fault is detected, the battery pack is waken up; if yes, the corresponding front-end unit transmits an alarm signal to the battery management unit along a direction opposite to the communication direction so as to wake up the main control unit; when the main control unit is in a working state, starting from the front-end units connected with the bridging chip, each front-end unit monitors the corresponding battery pack, and when a fault is detected, the corresponding front-end unit sends an alarm signal to the main control unit along a direction opposite to the communication direction, the transmission directions of the alarm signal and the communication data coding signal are opposite, and the main control unit sends the alarm signal to the bridging chip; when the alarm signal and the communication data coding signal are located in the same communication line, the alarm signal and the communication data coding signal are mutually superposed and transmitted; therefore, when the main control unit is in the dormant state and the working state, the main control unit can receive the alarm signal in time.
本发明提供的菊花链的反向唤醒方法、电池管理系统以及设备,通过在主控单元处于休眠状态时,每个前端单元均对对应的电池组以及菊花链的通信状态进行监测,若检测到故障,则对应的前端单元沿通信方向的反方向向电池管理单元传递告警信号以唤醒主控单元;在主控单元处于工作状态时:从桥接芯片连接的前端单元开始,每个前端单元均对对应的电池组进行监测,且在检测到故障时,对应的前端单元沿通信方向的反方向向主控单元发送告警信号,告警信号和通信数据编码信号的传递方向相反,在告警信号和通信数据编码信号位于同一根通信线时,告警信号和通信数据编码信号相互叠加传送;从而实现主控单元在休眠状态以及工作状态时,均能及时接收到告警信号。
