Integration of quick charging stations in weak power grids

Abstract

The importance of electric and hybrid vehicles as a serious alternative to conventional-driven vehicles especially in urban areas increases. But the low capacity of the battery minimizes the use for the long distance. A quick charging time realized by a high power level of 50 kW (compared with a standard charging station) enables a higher scope per day. Therefore the development of an infrastructure for high power charging at places with public access like motorway service stations is essential for a wide utilization of electric vehicles. This paper deals with different concepts to integrate quick charging stations in power grids of weak infrastructure areas.
