Grid-Aware Electric Vehicle Charging Interface Design

Fossil fuels used by traditional internal combustion vehicles today are quite damaging to environment. Because of these fuels, global warming has reached a very dangerous point. However, fossil fuels are gradually depleting. Therefore, it is inevitable that electric vehicles, which are more environmentally friendly, more economical and quieter, will become widespread. However, since fully electric vehicles will receive all of their energy from the grid, the electrical grid must be ready for this situation and load. Since conventional grids will be insufficient to manage this load, smart grids, which are flexible, adaptive, synchronous and strong, are needed. The energy quality problems due to electric vehicles can only be minimized with smart grids. When energy demands and distribution over time compared, demands of electric vehicles is much greater and, more importantly, it demands this energy in a much shorter time demand of a residence. For this reason, before electric vehicles become widespread, grids need to become smart and possible problems and solution suggestions need to be examined. In this study, instead of classical fast or slow electric vehicle charging, a flexible charging interface that interacts with grid, vehicle user and vehicle was designed.
