The invention relates to the technical field of vehicle battery management, in particular to a battery charging overcurrent identification method and device, a cloud server and a storage medium, and the method comprises the steps: collecting the daily average mileage and vehicle end data of a target vehicle to generate a travel division table; extracting charging condition data of the target vehicle based on the travel division table, and determining the vehicle travel, the charging frame number and the proportion of overcurrent data in the temperature interval to the total according to the charging condition data and a preset charging current value; and obtaining a charging fitting value of the target vehicle according to the proportion, and obtaining a charging overcurrent identification result of the battery of the target vehicle according to the charging fitting value. According to the charging overcurrent identification method of the battery provided by the embodiment of the invention, the charging overcurrent data is fitted based on the multi-source data such as the vehicle travel, the environment temperature and the charging mode, and the abnormal vehicle is monitored in a predictive manner, so that the dynamic identification of the charging overcurrent and the intelligent formulation of the response strategy are realized; therefore, the charging safety and efficiency are improved.

    本发明涉及车辆电池管理技术领域,特别涉及一种电池的充电过流识别方法、装置、云服务器及存储介质,方法包括:采集目标车辆的日均行驶里程和车端数据,以生成行程划分表;基于行程划分表提取目标车辆的充电工况数据,并根据充电工况数据和预设的充电电流值确定车辆行程、充电帧数、温度区间中过电流数据与总体的比例;根据比例得到目标车辆的充电拟合值,并根据充电拟合值得到目标车辆的电池的充电过流识别结果。根据本发明实施例的电池的充电过流识别方法,基于车辆行程、环境温度、充电模式等多源数据对充电过流数据进行拟合并对异常车辆预测性地进行监测,从而实现对充电过流的动态识别和响应策略的智能制定,从而提高充电安全性和效率。
