Method for selecting sites of battery distribution centers of battery replacing station system for electric automobiles

Abstract

The invention relates to a method for selecting the sites of battery distribution centers of a battery replacing station system for electric automobiles; and the method comprises the following steps of: for selecting the sites of battery distribution centers of the battery replacing station system, firstly zoning the battery replacing system, then determining the position of an optimal distribution center in each zone by adopting an improved center-of-gravity method, and using an assembly determined by the center-of-gravity method as an initial solution of a CFLP (China Federation of Logistics and Purchasing) method; determining the total expenses of the assembly of the distribution centers according to an initial supply scheme; moving the initial distribution center in a certain zone to alternate sites of other battery replacing stations in the local zone, selecting the site with the minimum distribution expenses to serve as a new distribution center, adjusting all the zones in the same way, thereby forming a distribution center assembly scheme, comparing the total expense of the distribution centers according to a new scheme and a former scheme, selecting the scheme with the lesser expenses as a new distribution scheme, and sequentially adjusting till the adjustment of the scheme for building the sizes of the distribution centers can not lead the expenses of the distribution scheme to be reduced, thereby obtaining the optimal site selection scheme.

Description

technical field [0001] The invention relates to a site selection method for a battery distribution center of an electric vehicle swap station system. Background technique [0002] Under the guidance of the concept of sustainable development, the application of various new energy sources is a key measure to reduce high energy consumption such as coal and petroleum and reduce greenhouse gas emissions. Electric vehicles use pure electricity as their energy source, with zero emissions and low noise during driving, which is an inevitable direction for the development of a new generation of vehicles. With the development of electric vehicles, their energy supplement is an important issue in the application. There are two types of energy supplement modes: charging type and battery swapping type. The charging method uses charging piles as the main equipment, which are mainly used in home warehouses and charging stations. However, it also has defects such as slow charging speed, c...

This step is very important, because it will directly affect the convergence speed of the entire calculation, sometimes the initial scheme obtained only through qualitative analysis cannot meet the requirements of the convergence speed, or even does not converge
