The invention discloses a method and a device for confirming a safety target of a power battery and a vehicle. The method comprises the steps that in response to the fact that a safety threshold value of a power battery in a vehicle is set and completed, the heating function of a whole vehicle heat management system in the vehicle on the power battery is triggered, and the safety threshold value is used for indicating that the power battery is in a heat damage state; a fault identifier of the power battery is obtained, and the fault identifier is used for representing a fault item enabling the power battery to be in a thermal damage state; according to a heating strategy corresponding to the fault identifier, heating the power battery by using a heating function to obtain a heating result; and based on the heating result, a safety target of the power battery is confirmed, and the safety target is used for determining the safety of the vehicle after a safety mechanism of the power battery is triggered under different fault items. The technical problem that the safety target of the power battery cannot be confirmed in the thermal damage state is solved.
本发明公开了一种动力电池的安全目标的确认方法、装置和车辆。其中,该方法包括:响应于设置完成车辆中动力电池的安全阈值,触发车辆中整车热管理系统对动力电池的加热功能,其中,安全阈值用于表示动力电池处于热损害状态;获取动力电池的故障标识,其中,故障标识用于表示使得动力电池处于热损害状态的故障项目;按照故障标识对应的加热策略,利用加热功能对动力电池进行加热,得到加热结果;基于加热结果,确认动力电池的安全目标,其中,安全目标用于确定在不同故障项目下触发动力电池的安全机制后车辆的安全性。本发明解决了无法在热损害状态下确认动力电池的安全目标的技术问题。
