The invention discloses a vehicle power failure early warning method and system, a readable storage medium and a vehicle. The method comprises the steps: generating a vehicle network management message based on the state of each node when the vehicle is powered off; judging whether the obtaining time of the vehicle network management message is within preset time or not; if the acquisition time of the vehicle network management message is not within the preset time, sending a sleep abnormal signal; and if the acquisition time of the vehicle network management message is within the preset time, acquiring a battery electric quantity signal value periodically sent by the vehicle, and judging whether the last battery electric quantity signal value is smaller than an early warning threshold value or not based on the vehicle dormant state information. Whether the vehicle has the risk of electricity bursting or not is judged through the battery electric quantity signal value and the whole vehicle dormancy state, and the service life of the vehicle is effectively prolonged. The trouble that the vehicle cannot be started is avoided for a user especially when the vehicle is used emergently.

    本发明公开一种车辆溃电预警方法、系统、可读存储介质及车辆,包括:基于获取车辆下电时各个节点的状态,生成车辆网络管理报文;判断所述车辆网络管理报文的获取时间是否在预设时间内;若所述车辆网络管理报文的获取时间不在预设时间内,发出休眠异常信号;若所述车辆网络管理报文的获取时间在预设时间内,获取车辆周期发送的电池电量信号值,基于所述车辆休眠状态信息判断最后一次的电池电量信号值是否小于预警阈值。通过电池电量信号值和整车休眠状态来判断车辆是否存在溃电的风险,有效得延长了车辆的使用寿命。让用户尤其在紧急用车时避免了启动不了车辆的困扰。
