The invention discloses a charging early warning method. Positioning modules are arranged on an electric vehicle and a charging pile, and the positioning modules, an electric vehicle controller and acharging pile controller are in communication connection with a service platform end; the electric automobile controller starts a battery electric quantity self-checking program at regular time and when the electric quantity of the battery is smaller than a preset value, enters a charging early warning program; the electric vehicle controller initiates a search request within a preset range of the charging pile to the service platform side; the electric vehicle controller receives a search result of the service platform end so as to drive the searched charging pile; and the search result is presented on a vehicle-mounted computer. According to the invention, the charging demand is discovered in time through the preset timing self-checking program of the vehicle, and the charging pile information in the preset range and the optimal driving route are automatically acquired through the request of the service platform end, so that the user experience is improved and the travel is facilitated.

    本发明公开了一种充电预警方法,在电动汽车和充电桩上设置定位模块,所述的定位模块以及电动汽车控制器以及充电桩控制器通信连接服务平台端;电动汽车控制器定时启动电池电量自检程序;当电池电量小于预设值时,进入充电预警程序:电动汽车控制器向服务平台端发起充电桩预设范围内的搜索请求;电动汽车控制器接收服务平台端的搜索结果以向搜索到的充电桩行驶;搜索结果呈现在车载电脑上。本发明通过车辆预设定时自检程序及时发现充电需求,并自动通过服务平台端请求获取预设范围内的充电桩信息,以及最佳的行驶路线,提高用户体验,方便出行。
