The invention relates to the technical field of new energy vehicle power battery safety, and provides a new energy vehicle voltage difference abnormity monitoring method and system and a storage medium, and the monitoring method comprises the steps: obtaining the voltage difference abnormity data of each vehicle in the measured vehicles within a preset number of days; and the change trend of the voltage difference abnormal data is obtained, the rising ratio of the voltage difference curve of the vehicle within the preset number of days is calculated, and when the ratio reaches a preset value, it is judged that the voltage difference of the vehicle is abnormal. Existing data are fully utilized, and the voltage difference data are not limited to the charging data by dividing the vehicle state.
本发明涉及新能源汽车动力电池安全技术领域,提供了一种新能源车辆电压差异常的监控方法、系统及存储介质,监控方法包括,获取预设天数内所测车辆中,每台车辆的电压差异常数据。获取电压差异常数据的变化趋势,计算该车辆预设天数内电压差曲线上升的比率,当所述比率达到预设值时,判定该车辆的电压差异常。本发明充分利用已有数据,通过划分车辆状态,使得压差数据不局限于充电数据。
