Energy distribution method and device of electric vehicle and vehicle

Abstract

The invention provides an energy distribution method and device for an electric vehicle and the vehicle. The method comprises the steps of obtaining information of the current environment where the vehicle is located and the current vehicle running state; according to a preset reference energy consumption model, obtaining reference energy consumption of the vehicle in the current vehicle running state and the current environment information, wherein the reference energy consumption model is obtained by correcting the actual energy consumption of the vehicle under different vehicle running states and environment information; according to the reference energy consumption and the residual energy, calculating the travelable mileage; determining the target maximum allowable discharge power of the vehicle according to the travelable mileage and the current display mileage of the vehicle; and according to the target maximum allowable discharge power, performing energy distribution on energy consumption accessories of the vehicle. The influence of the current running state and environment of the vehicle on the energy consumption of the vehicle is fully considered, the energy distribution of the energy consumption accessories of the whole vehicle is adjusted in time, and the target mileage is promoted to be achieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an energy distribution method, device and vehicle of an electric automobile. Background technique [0002] As the world's environmental protection issues and energy crisis become more and more prominent, new energy electric vehicles with the characteristics of saving fuel energy, low exhaust emissions, less pollution, and low noise have become the goal pursued by people. At present, the development and popularization of electric vehicles is facing many challenges. In particular, the limitation of battery technology still makes the driving range a major obstacle for the development of electric vehicles. Existing vehicle energy allocation strategies generally specify certain energy demand priorities and allocate power battery energy in a fixed order. Although existing vehicle energy allocation strategies limit vehicle power consumption to power The battery is within the capabi...

At present, the development and popularization of electric vehicles are facing many challenges. In particular, the limitation of battery technology still makes driving range the main obstacle for the development of electric vehicles.

Existing vehicle energy allocation strategies generally specify certain energy demand priorities and allocate power battery energy in a fixed order. Although the existing vehicle energy allocation strategies limit vehicle power consumption to power Within the capacity of the battery, but failing to adjust the energy distribution of the vehicle in time according to the actual driving situation, the remaining mileage of the electric vehicle will be shortened
