The invention provides a battery SOC correction system of an electric vehicle, a control method of the battery SOC correction system, a storage medium and the electric vehicle, and the battery SOC correction system comprises a data collection module which is used for collecting the historical value of the state of charge of a battery when the last driving of the electric vehicle is finished and before a battery management system is shut down and powered off; the data transmission module is used for acquiring the charge state historical value acquired by the data acquisition module when the last driving of the electric vehicle is finished, uploading the charge state historical value to a cloud server, acquiring a charge state awakening value of the battery when the electric vehicle is restarted after standing, and uploading the charge state awakening value to the cloud server; and the cloud server is used for feeding back the charge state initial value of the starting of the electric vehicle to a battery management system of the electric vehicle or an Internet of Vehicles user terminal according to the charge state historical value and the charge state wake-up value uploaded by the data transmission module. According to the scheme, errors possibly generated in the SOC estimation process of the battery can be reduced, and the estimation accuracy is improved.
本发明提供一种电动车辆的电池SOC矫正系统及其控制方法、存储介质及电动车辆,电池SOC矫正系统,包括:数据采集模块,用于在电动车辆上次行车结束时,电池管理系统关机下电前,采集电池的荷电状态历史值;数据传输模块,用于获取数据采集模块在电动车辆上次行车结束时采集的所述荷电状态历史值,并上传至云端服务器,以及在电动车辆静置后再次启动时,获取所述电池的荷电状态唤醒值,并上传至云端服务器;云端服务器,用于根据数据传输模块上传的所述荷电状态历史值和荷电状态唤醒值向电动车辆的电池管理系统或车联网用户终端反馈电动车辆本次启动的荷电状态初始值。本发明方案能够减小电池SOC估算过程中可能产生的误差,提高估算准确性。
