The invention provides a vehicle electric quantity prediction method and device, and the method comprises the steps: obtaining the current position of a target vehicle, the starting time of the vehicle, and the current electric quantity of a battery when the starting of the target vehicle is detected; according to a pre-constructed prediction model and the vehicle starting time, predicting the maximum destination position and the predicted travel mileage of the travel; predicting the power consumption of the travel according to the current position, the maximum destination position and the predicted travel mileage; judging whether the current trip power consumption is greater than the current battery electric quantity; and if yes, outputting first prompt information for prompting that the electric quantity of the trip is insufficient. Therefore, the method and the device can remind the user in advance under the condition that the electric quantity is not enough to support the vehicle to run to the destination, so that the mileage anxiety of the user is effectively reduced, and the user can make sufficient preparation and planning for subsequent driving.

    本申请提供一种车辆电量预测方法及装置,该方法包括:当检测到目标车辆启动时,获取目标车辆的当前位置、车辆启动时间以及当前电池电量;根据预先构建的预测模型和车辆启动时间,预测本次出行的最大目的地位置和预测出行里程;根据当前位置、最大目的地位置和预测出行里程,预测本次出行电耗;判断本次出行电耗是否大于当前电池电量;如果是,则输出用于提示本次出行电量不足的第一提示信息。可见,该方法及装置能够在电量不足以支撑车辆行驶至目的地的情况下提前提醒用户,从而有效地降低用户的里程焦虑,进而使得用户能够对后续的驾驶做好充足的准备和规划。
