A vehicle quiescent current monitoring method and device relates to the technical field of vehicles, and the method comprises the steps: obtaining a vehicle quiescent current value in a plurality of preset timing cycles, when any timing cycle ends, if the vehicle quiescent current value is higher than a preset quiescent current threshold, adding 1 to an abnormal count, and if the abnormal count is greater than or equal to a preset abnormal count threshold, adding 1 to the abnormal count; an abnormal controller is positioned, and the vehicle placement duration is calculated according to the storage battery parameters and the whole vehicle static current value; and judging whether the vehicle placement duration is lower than a preset placement duration threshold value or not, if so, cutting off a power supply of an abnormal controller, and if not, entering a next timing period. The power supply is cut off when the vehicle placement duration is lower than the preset placement duration threshold, and the power supply is not cut off according to the whole vehicle quiescent current abnormity appearing at a single time, so that the quiescent current abnormity judgment accuracy is improved.

    一种整车静态电流监控方法及装置,涉及车辆技术领域,方法包括在预设的多个计时周期内,获得整车静态电流值,当任一计时周期结束时,若整车静态电流值高于预设的静态电流阈值,异常计数加1,若异常计数大于等于预设的异常计数阈值,定位异常控制器,并根据蓄电池参数和整车静态电流值计算车辆可置放时长;判断车辆可置放时长是否低于预设置放时长阈值,若是,切断异常控制器的电源,若否,进入下一计时周期。通过在车辆可置放时长低于预设置放时长阈值时切断电源,而非根据单次出现的整车静态电流异常切断电源,提高了静态电流异常判断的准确性。
