Configuration and constant volume method for charging facilities in electric taxi fast charging station

Abstract

The invention provides a configuration and constant volume method for charging facilities in an electric taxi fast charging station. The method comprises steps: a distribution law for station entering time intervals and charging durations of electric taxis is analyzed, and an in-station queuing model type of the electric taxi fast charging station is determined; the in-station investment cost and the user time cost in unit time are measured; an objective function for an in-station charging facility configuration optimization model and constraint conditions are determined; the in-station charging facility configuration optimization model is built, and the optimal configuration number of the in-station charging facilities is solved and obtained; and according to the optimal configuration number of the in-station charging facilities, the distribution capacity of the electric taxi fast charging station is calculated. The problems that the electric taxi fast charging station is low in load utilization rate, poor in distribution economy, unreasonable in facility number configuration and the like are solved, the electric taxi fast charging station investment cost and the user staying time cost are considered thoroughly, and reasonable resource configuration of the fast charging station is ensured.

Description

technical field [0001] The invention relates to the technical field of electric taxis, in particular to a charging facility configuration and capacity fixing method in a fast charging station for electric taxis. Background technique [0002] With the promotion of low-carbon economy and new energy strategy, the electric taxi industry is booming. Many large cities in China have proposed a strategy to electrify all taxis. In addition to the regular charging at parking stations, the construction of fast charging stations for electric taxis in the public sector will become the key to getting rid of battery capacity constraints and greatly increasing the mileage of electric taxis. . The construction of fast charging stations without planning and calculation will bring problems such as unbalanced services between stations and poor economic efficiency of power distribution within stations. Therefore, the economical planning method of fast charging stations is very important to ensu...

AI Technical Summary

Problems solved by technology

The construction of fast charging stations without planning and calculation will bring problems such as unbalanced services between stations and poor economic efficiency of power distribution within stations. Therefore, the economical planning method of fast charging stations is very important to ensure the interests of both investment and users

[0003] In terms of determining the capacity of the electric taxi fast charging station, the current existing technology is to calculate the total capacity of the electric taxi fast charging station according to the charging demand within the service area of ​​the electric taxi fast charging station, and then roughly calculate the number of charging facilities in the station , it is easy to cause problems such as low charging service level, charging queue congestion, etc. Unified station facility configuration without calculation will lead to unbalanced service between stations, low load rate, and poor investment economy
