Abstract

Electric vehicle charging systems which provide energy for electric vehicles is the infrastructure of the electric vehicle industry and the important part of strong and smart grid. Various power supply services for different charging mode are studied with special focus on fast charging load characteristics. Three different charging modes of electric vehicle is compared, and the load characteristics of fast Charge is researched in this paper. Using large number law and central limit theorem, a statistical model of electric vehicles´power demand is built, and the power maximum demand of many electric vehicles is calculated to provide technical basis for load forecast.
