The invention provides an electric vehicle charging early warning method and device. The method comprises the following steps: acquiring a destination position, a driving habit of a driver, a road congestion coefficient and a current vehicle remaining electric quantity; estimating power consumption according to the driving habit of the driver, the destination position and the road congestion coefficient; judging whether the vehicle can arrive at the destination position according to the current remaining electric quantity and power consumption of the vehicle; if not, calculating to-be-charged required electric quantity according to the current remaining electric quantity and power consumption of the vehicle; and outputting charging early warning information including the required electric quantity. Therefore, according to the method, charging early warning can be carried out in time during route navigation, and the situation that the electric vehicle breaks down in the driving process is avoided.

    本申请提供一种电动汽车充电预警方法及装置,该方法包括:获取目的位置、驾驶员驾车习惯、道路拥挤系数以及当前车辆剩余电量;根据驾驶员驾车习惯、目的位置以及道路拥挤系数,估算电耗;根据当前车辆剩余电量和电耗,判断是否能够到达目的位置;如果否,则根据当前车辆剩余电量和电耗,计算待充的需求电量;输出包括需求电量的充电预警信息。可见,该方法能够在路线导航时及时进行充电预警,避免电动车辆行驶在过程中造成抛锚的情况。
