The invention discloses a battery replacement reminding method and system during parking of a pure electric vehicle. The method comprises the following steps of receiving a vehicle stop signal; sending an acquisition instruction; receiving vehicle position information and vehicle remaining endurance mileage information after parking; finding out the position information of an available battery swap station closest to the vehicle, calculating the mileage from the vehicle to the nearest available battery swap station, and judging whether the vehicle residual endurance mileage * endurance coefficient is equal to or less than the mileage from the vehicle to the nearest available battery replacing station; and if the vehicle remaining endurance mileage * the endurance coefficient is equal to or smaller than the mileage of the vehicle to the nearest available battery swap station, sending a battery swap prompt to the mobile terminal. According to the battery replacement reminding method and system during parking of the pure electric vehicle, the problem that the vehicle cannot be driven to the nearest battery replacement station for battery replacement endurance due to the continuously reduced remaining endurance mileage of the vehicle due to the fact that the natural discharge of a power battery caused by long-time parking of the vehicle is not considered in the prior art is solved.

    本发明公开了一种纯电动汽车停车换电提醒方法及系统,包括以下步骤:接收车辆停止信号;发送获取指令;接收停车后的车辆位置信息和车辆剩余续航里程信息;找到离车辆最近的可用换电站位置信息,并计算出车辆至最近的可用换电站的里程,判断车辆剩余续航里程*续航系数是否等于或小于车辆至最近的可用换电站的里程,若车辆剩余续航里程*续航系数等于或小于车辆至最近的可用换电站的里程,则发送换电提醒至移动终端。本发明一种纯电动汽车停车换电提醒方法及系统,解决现有存在没有考虑因车辆长时间停放导致的动力电池自然放电的问题,从而造成不断减少的车辆剩余续航里程无法将车驱驶到最近一个换电站进行换电续航的问题。
