The invention provides a low-electric-quantity reminding method and system for an electric automobile, and relates to the field of electric automobiles; the method comprises the steps that 1, a battery electric quantity sensor collects electric quantity information of a power battery, and sends the electric quantity information to a battery management system; 2, the battery management system generates an electric quantity signal according to the received electric quantity information, the electric quantity signal is transmitted to a positioning system through a controller local area network, and the electric quantity signal comprises the remaining electric quantity and the remaining mileage; 3, the positioning system collects the distribution information of the charging stations in a preset range, and sends the distribution information of the charging stations in the preset range to a display; and 4, the display plans a charging route according to the charging station distribution information and the remaining mileage in the preset range and the reminding mode corresponding to the range of the remaining mileage proportion. When the electric quantity of the electric vehicle is low, the driver is effectively reminded, the driver is guided to make a correct response, so that the driver is helped to plan a reasonable charging route, and the user experience is improved while driving safety is guaranteed.

    本发明提供一种用于电动汽车的低电量提醒方法及系统,涉及电动汽车领域,包括步骤一:电池电量传感器采集动力电池的电量信息,将电量信息发送到电池管理系统;步骤二:电池管理系统根据接收到的电量信息生成电量信号,将电量信号通过控制器局域网传输到定位系统,电量信号包括剩余电量和剩余里程;步骤三:定位系统采集预设范围内充电站分布信息,将预设范围内充电站分布信息发送到显示器;步骤四:显示器结合预设范围内充电站分布信息和剩余里程,与剩余里程比例所处范围对应的提醒方式规划充电路线。本发明在电动汽车电量较低时有效地提醒驾驶员,引导驾驶员做出正确的反应,帮助驾驶员规划合理充电路线,保证行车安全的同时提高用户体验感。
