Problems solved by technology

[0004] In order to solve the shortcomings of the existing fixed charging facilities, the present invention provides a charging method for electric vehicles based on the mobile charger mode. It does not need to increase the capacity of the distribution network and build a new parking space, and it can be installed in large-scale fixed charging facilities that are not suitable for new construction. In the area of ​​charging facilities, use the existing parking lot to build charging service stations, and configure mobile chargers to charge electric vehicles

Embodiment Construction

[0096] In this embodiment, an electric vehicle charging method based on the mobile charger mode is applied to a charging service station composed of N mobile chargers and provides charging services for M electric vehicles; the charging service station The preparation time for the charging process is recorded as Δt. In specific implementation, set the charging process preparation time Δt of the charging service station as: Δt=5min;

[0097] Mark N mobile chargers as MC={MC 1 ,MC 2 ,...,MC n ,...,MC N }, 1≤n≤N; MC n Indicates the nth level mobile charger; the nth level mobile charger MC n The number is NUM n ; Put the nth level mobile charger MC n The free time of is denoted as T n ; Put the nth level mobile charger MC n The free capacity is recorded as C n ; N mobile chargers MC are based on their idle time T = {T 1 ,T 2 ,...,T n ,...,T N } In ascending order; when the idle time T is the same, according to their respective numbers NUM = {NUM 1 ,NUM 2 ,...,NUM n ,...,NUM N } Is sort...

Abstract

The invention discloses an electric vehicle charging method based on a mobile charger mode. The electric vehicle charging method includes the steps: initializing charging demand parameters of M EV (electric vehicles) and operating state parameters of N MC (mobile chargers); setting m=1 and n=1; judging whether m is less than or equal to M or not; executing the step 4 if m<=M; otherwise, finishing calculation of charging schemes of the M electric vehicles; calculating and outputting the charging scheme of the m electric vehicle and charging service station operating parameters, and updating the operating state parameters of the mobile chargers; assigning m+1 to m, and setting n=1; executing the step 3. The electric vehicle charging method can provide viable charging schemes for electric vehicle users based on the mobile charger mode, overcomes the shortcomings of limitation of fixed charging facilities by distribution network capacity and the number of parking spaces and accordingly solves the problem of charging difficulty of the electric vehicles in old urban areas of tier one and two cities.

Description

Technical field [0001] The invention designs an electric vehicle charging method based on a mobile charger mode, which belongs to the technical field of orderly charging of electric vehicles. Background technique [0002] The large-scale application of electric vehicles puts forward higher requirements on the charging infrastructure. The "Electric Vehicle Charging Infrastructure Development Guide (2015-2020)" clearly stated that the goal of my country’s charging infrastructure development is to build 12,000 centralized charging stations and 4.8 million decentralized charging piles by 2020 to meet the needs of 5 million electric vehicles nationwide. Car charging demand. [0003] However, in the old urban areas of first- and second-tier cities where electric vehicles are developing rapidly, it is not suitable due to the restrictions on the capacity of the distribution network and the number of parking spaces, as well as the high cost and difficulty of increasing the capacity of the d...
