Embodiment 1

[0042] 1 Problem description

[0043] 1.1 Demand Analysis of Rescue Stations

[0044] At present, a fast-charging network with highways as the backbone network is rapidly forming, which is expected to solve the long-distance travel problem of electric vehicles. However, if an electric vehicle cannot reach the fast charging station on the expressway due to a failure of the fast charging station or insufficient power, it will cause traffic jams and rear-end collisions. Therefore, emergency rescue of electric vehicles is an urgent problem to be solved. important question. There are many reasons why electric vehicles cannot be charged, and they can be roughly classified into fast charging station failures, electric vehicle failures, electric vehicle power shortages, etc. The detailed fishbone diagram is as follows: figure 1 shown.

[0045] Among the above factors, the probability of fast charging station failure and electric vehicle failure is relatively small, and the probabil...

Abstract

The invention discloses an expressway electric vehicle emergency rescue station site selection constant volume method and system. The goal of minimizing the social yearly cost is achieved; on the premise that the rescue timeliness requirement is guaranteed, benefits of a station builder and an electric vehicle user are considered, the number and positions of rescue stations and the number of rescue vehicles in the station are decided by comprehensively considering influence factors such as the failure rate of the fast charging station, the vehicle flow, the electricity price and the station building cost, and the built model is solved by adopting a self-adaptive genetic algorithm. Taking the Shandong expressway fast charging service network as an example, the article verifies the effectiveness of the method.

Description

technical field [0001] The invention relates to a method and system for site selection and capacity determination of expressway electric vehicle emergency rescue stations. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In response to government planning, the State Grid Corporation of China has built more than 1,200 expressway fast charging stations in more than 20 provinces and municipalities directly under the Central Government. Although the basic charging facilities of highways are becoming more and more perfect, problems such as failure of fast charging stations or insufficient power of electric vehicles to reach fast charging stations still limit the promotion and use of electric vehicles. Therefore, it is of great practical significance to study the emergency rescue methods of electric vehicles in the highway environment to promote...
