The invention relates to the technical field of new energy vehicles, in particular to a charging reminding method and device for an electric vehicle. The method comprises the steps that vehicle travel data are collected in real time and preprocessed; establishing a charging position information base according to the chargeable position information of the current vehicle; updating the travel power consumption trend according to the power consumption information of each travel and calculating the estimation result of the power consumption of the next travel of the vehicle; and selecting a charging recommendation position in the charging position information base according to the power consumption estimation result, and planning charging recommendation time and a charging route. According to the method, the power consumption information in the vehicle driving process and the current vehicle chargeable position information are collected at the same time, and the charging position information base for the current vehicle is established according to all the chargeable positions of the current vehicle. Therefore, in the next travel of the current vehicle, the prompt is accurately made according to the demand of the vehicle owner.

    本申请涉及新能源汽车技术领域,具体涉及一种电动车的充电提醒方法及充电提醒装置。其包括:实时收集车辆行程数据并进行预处理;根据当前车辆的可充电位置信息建立充电位置信息库;根据每次行程耗电信息对行程耗电趋势进行更新并计算下一次车辆行程的耗电量的估算结果;根据耗电量估算结果在充电位置信息库中选择充电推荐位置,并规划充电推荐时间和充电路线。本申请通过同时收集车辆行驶过程的耗电量信息和当前车辆可充电位置信息,根据当前车辆所有可充电位置建立针对于当前车辆的充电位置信息库。进而在当前车辆下一次的行程中,精准地按照车主需求做出提示。
