The invention provides an electric vehicle charging remaining time prediction method and system. On the basis of fully considering various factors influencing the estimation accuracy of the charging remaining time in different working modes and different working scenes, a processing mode is provided, and the estimation accuracy of the charging remaining time is further improved. And the displayed charging time is corrected by matching the real-time reference information of the rechargeable battery of the electric vehicle in the charging process with historical reference information of the rechargeable battery of the vehicle stored or acquired by the cloud. Meanwhile, a self-adaptive following strategy of the charging remaining time is provided, the display value of the charging remaining time can be self-adaptively corrected according to the difference, and the defects that the accuracy is low due to the fact that the vehicle only depends on local calculation, and continuous optimization cannot be conducted according to the real vehicle condition are overcome.

    本申请提供一种电动汽车充电剩余时间预测方法和系统。本发明在充分考虑不同工作模式以及不同工作场景中影响充电剩余时间估算准确度的多种因素的基础上,提供了一种处理方式,进一步提高了充电剩余时间估算的准确度。通过处于充电过程中电动汽车充电电池的实时参考信息与云端储存或获取的历史汽车充电电池参考信息的匹配,对所显示的充电时间进行校正。同时也提供了充电剩余时间的自适应跟随策略,可以根据差异自适应修正充电剩余时间的显示值,解决了车辆只依赖本地计算导致准确性低、无法根据实车状况持续优化的缺点。
