Description
Summary:The importance of electric and plug-in hybrid vehicles as a serious alternative to conventional-driven vehicles especially in urban areas increases. The main disadvantage for the use of such vehicles for long distance is the low capacity of the battery. A quick charging time realized by a high power level of 50 kW (compared with a standard charging station) describes a feasible technical solution for a higher driving range per day. This solution requires the development of an infrastructure for high power charging at places with public access like motorway service stations and can lead to a wide utilization of electric vehicles. This paper deals with voltage control at the grid connection point by quick charging stations for a large scale integration in areas with weak power grid infrastructure.
