Embodiment Construction

[0096] In this embodiment, a charging method for an electric vehicle based on a 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 charging process preparation time is recorded as Δt. In the specific implementation, the charging process preparation time Δt of the charging service station is set as: Δt=5min;

[0097] Record 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 recorded as NUM n ; Set nth level mobile charger MC n T n ; Set nth level mobile charger MC n The free capacity of is denoted as C n ; N mobile chargers MC are based on their respective idle time T={T 1 , T 2 ,...,T n ,...,T N} in ascending order; when the idle time T is the same, according to the respective numbers NUM={NUM 1 , NUM 2 ,...,NUM n ,...,NUM N} in a...

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, and belongs to the technical field of orderly charging of electric vehicles. Background technique [0002] The large-scale application of electric vehicles has put forward higher requirements for charging infrastructure. The "Guidelines for the Development of Electric Vehicle Charging Infrastructure (2015-2020)" clearly stated that the goal of my country's charging infrastructure development is to build 12,000 centralized charging and swapping stations and 4.8 million decentralized charging piles by 2020 to meet the needs of the country's 5 million electric vehicles. car charging needs. [0003] However, in the old urban areas of first- and second-tier cities where electric vehicles are developing rapidly, due to the limitation of distribution network capacity and the number of parking spaces, as well as the high cost and difficulty of increasing the capacity of t...
