The invention discloses a BMS awakening method and device and a storage medium, and belongs to the technical field of battery safety. Before the BMS is dormant, an awakening threshold corresponding to first sampling information is determined based on the extreme value of the obtained first sampling information of the battery cell; and after the BMS is dormant, the sampling chip collects second sampling information of the battery cell in the dormant state of the BMS, and sends a wake-up signal to the BMS when it is determined that the second sampling information of the battery cell reaches a wake-up threshold. Therefore, the BMS can be awakened in time based on the awakening signal, so that the BMS can discover the battery safety problem in time.
一种BMS的唤醒方法、装置及存储介质,属于电池安全技术领域。所述BMS在休眠前,基于获取的电芯的第一采样信息的最值确定对应于第一采样信息的唤醒门限;在BMS休眠后,由采样芯片采集BMS休眠状态下电芯的第二采样信息,并在确定电芯的第二采样信息达到唤醒门限时向BMS发送唤醒信号。由此,BMS基于该唤醒信号可以被及时唤醒,因此BMS可以及时发现电池安全问题。
