Electric vehicles (EVs) will play a central role in future road traffic. To cope with the limited range and long charging times of such vehicles, a public fast-charging infrastructure will be deployed to recharge EV batteries. A challenge in such an infrastructure is the high costs associated with electrical peak loads; a charging station along a busy highway may see hundreds of EVs per hour. D...

Electric vehicles (EVs) and plug-in hybrid vehicles (PHEVs) are rapidly gaining popularity on our roads. Besides a comparatively high purchasing price, the main two problems limiting their use are the short driving range and inconvenient charging process. In this paper we address the following by presenting an automatic robot-based charging station with 3D vision guidance for plugging and unplu...

This paper is devoted to the infrastructure issues arising from the ultrafast charging of electric vehicles in the timeframe of ~5 minutes. To mitigate variances and peaks caused by high energy transfer rate and pulse-like load, an ultrafast charging station must be partially decoupled from the utility grid by the usage of intermediate energy buffers. The perspective charging station load and i...

This paper addresses the principal service aspects for electric vehicles (EV), as well as issues related to energy storage design, charging station integration into power system and load management issues. It builds on the research conducted in the Flexible Electric Vehicle Charging Infrastructure project (Flex-ChEV) supported by the ERA-Net Smart Grid FP7 program. The principal asset of the pr...

This paper is aimed at modelling of a distinct smart charging station for electric vehicles (EVs) that is suitable for DC quick EV charging while ensuring minimum stress on the power grid. Operation of the charging station is managed in such a way that it is either supplied by photovoltaic (PV) power or the power grid, and the vehicle-to-grid (V2G) is also implemented for improving the stabilit...

This paper proposes a novel design for a solar-powered charger for low-power devices. The level of the charging current is controllable and any residue power is saveable to a rechargeable 9V battery. Two power sources (AC and solar) are used, and two charging speeds are possible. Quick charging is 20% of the battery output current (almost 180mA/hr) so the current is limited to 34 mA. Two types ...

Electric vehicle penetration in the transport section is increasing and replacing conventional fossil fuel based vehicles. Still, EV has not received success due to some limitations such as cost of vehicle, battery capacity availability charging station. The station depends on its geographical location. At same time, location electrical network affects energy loss voltage deviation. Therefore, ...
