Low electric quantity reminding method and system for electric vehicle

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method and system for reminding electric vehicles of low battery. Background technique [0002] With the increasingly prominent problem of environmental degradation and the penetration of automobiles into every corner of people's lives, the development of new energy vehicles has attracted the attention of countries all over the world. Most of the existing new energy vehicles use electricity as the energy source. Therefore, during the entire driving process of electric vehicles, the consumption state of the battery has a great impact on driving safety. In addition, the consumption state of the battery is easily affected by the environment. When the remaining power is insufficient Extremely prone to emergencies, which bring huge hidden dangers to driving safety. Therefore, before the battery power is low, it is very important to effectively remind the driver of the bat...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the low-battery reminder method of the prior art, in addition to reminding the driver, does not consider how to guide the driver to make a correct response in the future, and cannot provide a reasonable route for the driver, and it is difficult to ensure driving safety to a greater extent. poor
