Electric vehicle electric energy management method

Abstract

The invention discloses an electric vehicle electric energy management method comprising a vehicle navigation system; the method comprises the following steps: obtaining vehicle position information, vehicle battery electric energy state information and vehicle engine real time work power; calculating the maximum driving range before the battery runs out according to the battery electric energy state information; calculating the reachable scope according to the position information and calculated driving range, and displaying available charging columns in the scope; when the number of the charging column is smaller than 1, sending alarms, and controlling the engine to reduce work power. The electric vehicle electric energy management method can calculate the battery electric energy and process the position information so as to obtain a safe and reliable endurance route, thus ensuring the electric vehicle to be timely charged.

Description

technical field [0001] The invention relates to an electric energy management method, in particular to an electric energy management method applied to an electric vehicle (Electric Vehicle). Background technique [0002] With the advent of electric vehicles, the need to supplement the electric energy of vehicles has also increased a lot. However, the electric vehicle can only use the battery as a source of electric energy, once the electric energy of the battery is exhausted, the electric vehicle will stop and cannot continue to move forward. Before charging stations and battery replacement stations became as popular as gas stations, most drivers still feared that the power provided by the battery would suddenly run out on the road, and such thinking also hindered the sales of electric vehicles. Contents of the invention [0003] The object of the present invention is to provide an electric energy management method for an electric vehicle in order to overcome the above-me...
