The invention relates to a power-off delay duration determination method and device, equipment and a storage medium, and relates to the technical field of electric vehicles. The method is applied to a vehicle and comprises the steps of determining a fault code of the vehicle and the number of people in the vehicle in response to a detected fault of the vehicle; determining the fault part of the vehicle and the fault level of the part based on the fault code of the vehicle, wherein the fault level is in direct proportion to the fault severity; and under the condition that the part meets the preset condition, the delayed power-off duration of the vehicle is determined according to the fault level of the part and the number of people in the vehicle. Therefore, under the condition that the vehicle breaks down, the appropriate power-off delay duration can be determined, and the safety and reliability of the vehicle in the fault mode are guaranteed.

    本申请涉及一种下电延迟时长的确定方法、装置、设备及存储介质,涉及电动汽车技术领域。应用于车辆,该方法包括:响应于检测到车辆出现故障,确定车辆的故障码以及车辆内的人员数量;基于车辆的故障码确定车辆出现故障的部位以及该部位的故障等级,故障等级与故障严重程度成正比;在该部位满足预设条件的情况下,根据该部位的故障等级以及车辆内的人员数量,确定车辆的延迟下电时长。由此,可以在车辆出现故障的情况下,确定合适的下电延迟时长,以保障车辆故障模式下的安全性和可靠性。
