The invention discloses a battery management system, a networking method and a power battery, the battery management system comprises a master node and a plurality of slave nodes, and the master node is in wireless communication with each slave node; the slave node monitors the communication state of the current channel in real time and sends a monitoring result to the master node; the main node receives and analyzes the monitoring result, and judges whether the communication state of the current channel meets a preset communication condition or not; when the communication state of the current channel does not meet the preset communication condition, the master node obtains a plurality of available channels meeting the preset communication condition, determines a target channel with the optimal communication state in the plurality of available channels according to a preset channel screening standard, and broadcasts a channel switching signal and a re-networking signal to the slave node; and after receiving the channel switching signal and the re-networking signal, the slave node re-networks with the master node through the target channel. The network can be recombined timely and effectively, the failure of the battery management system is avoided, and the communication stability of the battery management system is improved.

    本发明公开一种电池管理系统、组网方法及动力电池,电池管理系统包括主节点及多个从节点,主节点与各个从节点之间进行无线通信;从节点实时监测当前信道的通信状态,并将监测结果发送至主节点;主节点接收并解析监测结果,并判断当前信道的通信状态是否满足预设通信条件;在当前信道的通信状态不满足预设通信条件时,主节点获取满足预设通信条件的多个可用信道,并根据预设信道筛选标准在多个可用信道中确定通信状态最优的目标信道,并向从节点广播切换信道信号和重新组网信号;从节点在接收到切换信道信号和重新组网信号后,通过目标信道重新与主节点组网。本发明能够及时有效地重组网络,避免电池管理系统失效,提高电池管理系统的通信稳定性。
