The invention provides a vehicle quiescent current abnormity monitoring method comprising the following steps: obtaining first voltage data of a storage battery, the first voltage data comprising a first voltage and a first time when a remote vehicle-mounted terminal collects the first voltage, the first time being a certain moment between a vehicle flameout state and a remote vehicle-mounted terminal dormancy state; second voltage data of the storage battery are obtained, the second voltage data comprise second voltage and second time when the remote vehicle-mounted terminal collects the second voltage, and the second time is a certain moment between the moment before the vehicle is started next time and the moment after the remote vehicle-mounted terminal is awakened; determining a unit voltage drop of the storage battery based on the first voltage data and the second voltage data; and if the unit voltage drop is higher than the voltage drop threshold, determining that the quiescent current of the vehicle is abnormal. According to the voltage change condition of the storage battery after flameout and before next starting, whether the static current abnormity occurs or not is determined, operation is easier than direct measurement of the static current of a single electric device, and the precision is high.

    本申请提供一种车辆静态电流异常监测方法,包括:获取蓄电池的第一电压数据,第一电压数据包括第一电压和由远程车载终端采集第一电压的第一时间,第一时间是介于车辆熄火后和远程车载终端休眠前之间的某一时刻;获取蓄电池的第二电压数据,第二电压数据包括第二电压和由远程车载终端采集第二电压的第二时间,第二时间是介于车辆下一次启动前和远程车载终端被唤醒后之间的某一时刻;基于第一电压数据和第二电压数据,确定蓄电池的单位电压降;若单位电压降高于压降阈值,则确定车辆的静态电流异常。本申请根据蓄电池在熄火后至下一次启动前的电压变化情况,确定是否发生了静态电流异常,比直接测量单个用电设备的静电电流更易操作,且精度较高。
