The invention provides a vehicle charging early warning method and a device, computer equipment and a storage medium, and the method comprises the steps: determining a target path of a target vehicle and target path information, wherein the target path is a path planned by the target vehicle and driving from a current position to a target position, the target path information comprises the environment temperature and the driving speed, the total energy consumption is calculated according to the environment temperature, the driving speed and preset energy consumption coefficients, and the energy consumption coefficients comprise the speed energy consumption coefficient and the temperature energy consumption coefficient; determining the available electricity quantity of the target vehicle according to the current electricity quantity percentage of the target vehicle and a preset electricity quantity percentage-electricity quantity curve, triggering charging early warning when the available electricity quantity is smaller than the total energy consumption, and calculating the total energy consumption according to the actual condition of the target path. The calculation error caused by indiscriminately calculating the total energy consumption according to the energy consumption in the unit distance given by a manufacturer is avoided, the accuracy of the vehicle charging early warning information is improved, and convenience is brought to a user to drive out.

    本发明提供了一种车辆充电预警方法、装置、计算机设备和存储介质,该方法包括:本发明实施例通过确定目标车辆的目标路径以及目标路径信息,目标路径为目标车辆规划的从当前位置行驶至目标位置的路径,目标路径信息包括环境温度和行驶速度,根据环境温度、行驶速度以及预设的能耗系数计算总能耗,其中,能耗系数包括速度能耗系数和温度能耗系数,根据目标车辆的当前电量百分比、预设的电量百分比-电量曲线确定目标车辆的可用电量,在可用电量小于总能耗时触发充电预警,根据目标路径的实际情况来计算总能耗,避免无差别地按照厂家给定的单位距离内的能耗来计算总能耗所带来的计算误差,提高车辆充电预警信息的准确性,给用户驾车外出带来便利。
