The invention relates to an electric vehicle charging early warning method and a vehicle-mounted terminal. The method comprises the following steps: S1, providing the vehicle-mounted terminal; s2, monitoring the charging behavior of a user and the state of a battery management system through a vehicle-mounted terminal, and dynamically updating a safe endurance SOC threshold value; and S3, monitoring attenuation conditions of the SOC of the vehicle in time and space dimensions in a current state in real time through the vehicle-mounted terminal, estimating a safe endurance duration and a safe endurance mileage of the vehicle, traversing navigation paths of surrounding charging stations, and when the driving duration is less than the safe endurance duration or the travel is less than N of the charging stations with the safe endurance mileage being less than N, executing the step S3. And sending out a charging early warning prompt and feeding back selectable charging stations and paths conforming to the safe endurance duration or the safe endurance mileage. The electric vehicle can be charged in time, and the situation that the electric vehicle breaks down without electricity is greatly reduced.
本发明涉及一种电动车充电预警方法及车载终端,该方法可包括以下步骤:S1.提供车载终端;S2.通过车载终端监测用户充电行为和电池管理系统状态,动态地更新安全续航SOC阈值;以及S3.通过车载终端实时监测当前状态下车辆SOC在时间和空间维度的衰减情况,预估其安全续航时长和安全续航里程,并遍历周边充电站的导航路径,当驾驶时长小于安全续续航时长或行程小于安全续航里程的充电站点数小于N时,发出充电预警提示并反馈出符合安全续航时长或安全续航里程的可选充电站点及路径。本发明可以确保电动车得到及时充电,大大降低了电动车无电抛锚的情况发生。
