The invention discloses an intelligent judgment method for an electric charging moment, and belongs to the field of electric vehicles. The method comprises the following steps: S1, determining an early warning coefficient omega in real time according to personal attributes of a driver and driving data of the electric vehicle; s2, obtaining the remaining driving range Sremain of the electric vehicle and the distance Sarrive between the electric vehicle and the target charging station in real time; and s3, judging whether the Sremain-Sarrive is smaller than an early warning threshold value or not, if yes, sending a charging alarm prompt, and determining the early warning threshold value according to the total driving range of the electric vehicle and the early warning coefficient omega. According to the invention, personal attributes of drivers, energy consumption conditions of vehicles, real-time road conditions of roads and other information are considered; the mileage anxiety of the driver is graded; according to the mileage anxiety degree and the actual charging requirement of the driver, charging early warning and charging station reservation are carried out for the drivers withdifferent mileage anxiety degrees at proper time, the electric vehicle can be charged timely and accurately, the mileage anxiety of the driver is effectively relieved, and the traveling quality of the electric vehicle driver is improved.

    本发明公开了一种电动充电时刻智能判定方法,属于电动汽车领域。其包括S1:根据驾驶员的个人属性和电动汽车的行驶数据实时确定预警系数ω;S2:实时获得电动汽车的剩余续驶里程S和电动汽车与目标充电站的距离S;S3:判断S‑S是否小于预警阈值,若是,则发出充电报警提示,其中预警阈值根据电动汽车总续驶里程和预警系数ω确定。本发明考虑驾驶员的个人属性、车辆的能耗状况、道路的实时路况等信息,通过对驾驶员里程焦虑的分级,根据驾驶员的里程焦虑程度和实际充电需求,为不同里程焦虑的驾驶员在合适的时机进行充电预警和预约充电站,能够及时准确的对电动汽车进行充电,有效的缓解驾驶员的里程焦虑,提升电动汽车驾驶员的出行品质。
