Abstract

The invention provides an ordered charging scheduling method for an electric vehicle. The method comprises the steps of calculating out energy consumption of the electric vehicle in a current work condition according to a pre-established driving range predicting model of the electric vehicle; calculating out a driving range of the electric vehicle according to the energy consumption of the electric vehicle in the current work condition and a current SOC; calculating out a charging quantity of the electric vehicle according to a pre-established electric vehicle power battery service life model when a proportion between the driving range of the electric vehicle and a predicted driving range of the electric vehicle before next charging is smaller than a set threshold value; scheduling a charging process of the electric vehicle according to the charging quantity and departure time of the electric vehicle and a current load condition of a power distribution network by taking the minimum difference between peak and valley of the local-area power distribution network as an optimizing target. According to the ordered charging scheduling method, meeting a driving behavior characteristic of a driver is used as a base, the service life of a power battery of the electric vehicle is prolonged by reasonably guiding the electric vehicle to charge and discharge, the difference between peak and valley of a network load is reduced, and stable operation of a power network is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an orderly charging scheduling method for electric vehicles. Background technique [0002] Guaranteeing the sustainable supply of energy is a link that cannot be ignored in the national energy security strategy. It is imperative to formulate an energy security strategy that is in line with my country's sustainable development. On the one hand, improving the energy environment and reducing carbon emissions is an important consensus for sustainable energy development. On the other hand, as an important form of global energy, fossil energy is vulnerable to political, economic, terrorist attacks and other aspects. Energy conservation, emission reduction and sustainable development have made traditional motor vehicles powered by internal combustion engines face the fate of being eliminated, while electric vehicles using clean energy will inevitably become a new dire...
