The invention provides a battery thermal runaway disposal method and a vehicle, and relates to the technical field of vehicles. The battery thermal runaway disposal method is applied to the electric vehicle, the electric vehicle comprises a main battery pack and a standby battery pack, and the battery thermal runaway disposal method comprises the steps that a battery pack thermal runaway event is monitored; when the battery pack thermal runaway event indicates that the main battery pack is in thermal runaway, controlling or waiting for the speed of the electric vehicle to zero; and the main battery pack is controlled to be separated from the electric vehicle, and the standby battery pack is controlled to supply power to the electric vehicle. When the thermal runaway event occurs in the main battery pack, the vehicle speed of the electric vehicle is controlled or waited to be zero, the safety of separation of the main battery pack is guaranteed, then the main battery pack with thermal runaway is controlled to be separated from the electric vehicle, and therefore the safety of the electric vehicle is guaranteed, and finally the standby battery pack supplies power to the electric vehicle. And effective battery thermal runaway treatment is realized.
本发明提供了一种电池热失控处置方法及车辆,涉及车辆技术领域。本发明所述的电池热失控处置方法,应用于电动车辆,所述电动车辆包括主电池包和备用电池包,所述电池热失控处置方法包括:监测电池包热失控事件;当所述电池包热失控事件指示所述主电池包热失控时,控制或等待所述电动车辆的车速至零;控制所述主电池包脱离所述电动车辆,并控制所述备用电池包为所述电动车辆供电。本发明通过在主电池包发生热失控事件时,首先控制或等待电动车辆的车速至零,保证主电池包脱离的安全性,再控制热失控的主电池包脱离电动车辆,从而保证电动车辆的安全性,最后通过备用电池包为电动车辆供电,实现有效的电池热失控处置。
