Abstract: Embodiments of this application provide a battery management system (BMS) wake-up method, a BMS wake-up apparatus, and a storage medium, and pertains to the field of battery safety technologies. In this application, before a BMS hibernates, a wake-up threshold corresponding to first sampling information is determined based on an obtained extremum of the first sampling information of a battery cell. After the BMS hibernates, a sampling chip collects second sampling information of the battery cell when the BMS is hibernating, and transmits a wake-up signal to the BMS when it is determined that the second sampling information of the battery cell reaches the wake-up threshold. In this way, the BMS can be woken up in a timely manner by the wake-up signal, and therefore the BMS can find battery safety problems in a timely manner.
