AI Technical Summary
Technical Problem
When a vehicle is parked and in sleep mode, the battery management system cannot monitor the thermal runaway state of the battery pack in a timely manner, which leads to the failure to detect battery safety issues in a timely manner.
Method used
Before the BMS goes into sleep mode, the maximum and minimum values of the cell information collected by the sampling chip are used to determine the wake-up threshold. When the cell sampling information reaches the wake-up threshold, the sampling chip sends a wake-up signal to wake up the BMS, enabling timely detection of battery safety issues.
Benefits of technology
It enables timely detection of battery safety issues during BMS hibernation, improving the accuracy and timeliness of battery safety monitoring.

Abstract
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。
