Today, demand to electric and hybrid electric vehicles (EVs, HEVs) increases day by day due to both environmental factors and limited fossil fuel resources. With EVs and HEVs becoming widespread, some basic problems arise. One of the most important of these problems is that the users who want to charge their vehicles cause to over load on the power grid. Another problem is that charging stations are not widespread and charging station installation cost is high. This study deals with the design of a smart parking lot system that can provide collective charging services for electric and hybrid electric vehicles. In the proposed smart parking system, online booking assistance is provided and the location of charging stations is marked on the navigation so that users of EVs and HEVs can easily access the charging stations. Also, users via the designed mobile application can follow up and control booking inquiry, battery charge status, battery sharing permission and payment services. Another important feature provided by the proposed parking system is that the problem of excessive and irregular load to the power grid occurred during charging of vehicles located in the parking lot solve with the developed energy management algorithm. In the developed energy management algorithm, in case of the over loading of the power grid, the energy requirement for charging is provided from other vehicles for which prior permission for battery sharing has been obtained instead of the power grid. Thus, overloading of the power grid is prevented and, also drivers who give permission for battery sharing can derive a profit.
