The invention provides a method and device for predicting the remaining charging time of a vehicle, equipment and a medium. The method comprises the following steps: acquiring an actual state parameter of a vehicle, a parameter of a charging pile for charging the vehicle, an environment state parameter of the vehicle and residual local estimated time of vehicle charging; classifying the actual state parameters, the parameters of the charging pile and the environment state parameters to obtain a first type parameter set and a second type parameter set; obtaining a sub-database having a parameter attribute corresponding to the first type parameter set, and predicting the residual cloud pre-estimation time of vehicle charging according to historical parameters matched with the second type parameter set in the sub-database; and performing correction based on a difference value between the local estimated time and the cloud estimated time to obtain the predicted remaining charging time of the vehicle. The accuracy of predicting the remaining charging time of the vehicle can be improved.

    本申请提供了一种车辆的充电剩余时间的预测方法、装置、设备及介质。该方法包括:获取车辆的实际状态参数、对车辆充电的充电桩的参数、车辆的环境状态参数以及车辆充电剩余的本地预估时间;对实际状态参数、充电桩的参数以及环境状态参数分类得到第一类型参数集合和第二类型参数集合;获取与第一类型参数集合具有对应参数属性的子数据库,并根据子数据库中与第二类型参数集合相匹配的历史参数,预测车辆充电剩余的云端预估时间;基于本地预估时间与云端预估时间的差值进行修正,得到车辆的预测充电剩余时间。本申请能够提高预测车辆的充电剩余时间的准确性。
