The invention provides a vehicle battery detection method and system based on a charging pile and the charging pile, and relates to the technical field of new energy automobiles, and the method comprises the steps: obtaining a vehicle identification code and vehicle charging data based on the communication between a vehicle charging stage and the charging pile; according to the vehicle identification code, obtaining shared charging data of the same type as the vehicle battery; according to the vehicle charging data and the shared charging data, predicting to obtain a predicted SOC value of the vehicle battery; and comparing the predicted SOC value with the read SOC value read at the corresponding moment to obtain an SOC relative estimation error. According to the invention, the accurate prediction of the SOC can be realized, and the estimation error of the battery management system for the SOC can be obtained.

    本发明提供了一种基于充电桩的车辆电池检测方法、系统及充电桩,涉及新能源汽车技术领域,所述方法包括:基于车辆充电阶段与充电桩的通信,获取车辆识别码与车辆充电数据;根据车辆识别码,获取与车辆电池类型相同的共享充电数据;根据车辆充电数据和共享充电数据,预测得到车辆电池的预测SOC值;比较预测SOC值与对应时刻读取到的读取SOC值,得到SOC相对估算误差。本发明能够实现对于SOC的准确预测,并得到电池管理系统对于SOC的估计误差。
