The invention relates to the technical field of vehicles, in particular to a power-lack positioning method and device for a vehicle, the vehicle and a storage medium, and the method comprises the steps: collecting a unit quiescent current consumption value of a storage battery of the vehicle, and judging whether the unit quiescent current consumption value is greater than a preset threshold value or not; if the unit quiescent current consumption value is greater than a preset threshold value, acquiring the working current of the monitored controller; and when it is determined that the monitored controller is in a working state according to the working single flow, acquiring an abnormal wake-up node and abnormal wake-up time of the monitored controller, creating a first diagnostic identifier (DID), and storing the abnormal wake-up node and the abnormal wake-up time to the first DID. Therefore, the problem that the electric leakage controller cannot be positioned when the electric leakage controller is abnormal, cannot send an abnormal reason or correctly sends an abnormal reason in an actual project is solved, so that the problem of the electric leakage controller can be positioned and recorded under the condition that the electric leakage controller is abnormal.
本申请涉及车辆技术领域,特别涉及一种车辆的亏电定位方法、装置、车辆及存储介质,其中,方法包括:采集车辆蓄电池的单位静态电流消耗值,并判断单位静态电流消耗值是否大于预设阈值;若单位静态电流消耗值大于预设阈值,则获取被监控控制器的工作电流;在根据工作单流确定被监控控制器处于工作状态时,获取被监控控制器的异常唤醒节点和异常唤醒时间,并创建第一诊断标识符DID,将异常唤醒节点和异常唤醒时间存储至第一DID。由此,解决在实际项目中,因为漏电控制器异常,无法发出或正确发出异常原因时,无法定位漏电控制器的问题,从而可以在漏电控制器异常的情况下,定位漏电控制器的问题并记录。
