The invention relates to the technical field of vehicles, and discloses a thermal runaway monitoring method and system after power-off dormancy and electronic equipment. The method comprises the following steps: when the battery management system is in a dormant state, acquiring first battery state data of a battery pack; if it is determined that the first battery state data exceed a set battery data threshold value, the battery management system is awakened; acquiring second battery state data of the battery pack, and analyzing the second battery state data to obtain a safety assessment result of the battery pack; and determining the thermal runaway state of the battery pack according to the second battery state data and/or the safety evaluation result. Thus, when the vehicle is in the power-off dormant state, if the risk of thermal runaway exists, the battery management system can be awakened in time, the obtained battery state data are analyzed through the battery management system, accurate monitoring of the thermal runaway of the battery pack is achieved, and the safety of a vehicle owner and personnel nearby the vehicle is effectively ensured.
本申请涉及车辆技术领域,揭示了一种下电休眠后的热失控监测方法、系统及电子设备。该方法包括:在电池管理系统处于休眠状态时,获取电池包的第一电池状态数据;若确定所述第一电池状态数据超出设定电池数据阈值,则唤醒所述电池管理系统;获取所述电池包的第二电池状态数据,并对所述第二电池状态数据进行分析,得到所述电池包的安全评估结果;根据所述第二电池状态数据和/或所述安全评估结果,确定所述电池包的热失控状态。如此,在车辆处于下电休眠状态时,如果存在热失控风险,也能及时唤醒电池管理系统,并通过电池管理系统对获取到的电池状态数据进行分析,实现对电池包热失控的精准监测,有效确保车主及车辆附近人员的安全性。
