Determine priority of changing of electric vehicles

An electric vehicle charging station enabling users to receive fast service with high or low priority, and keeping the ratio of average waiting times of low priority and high priority vehicles in the station at the same time at the target waiting time rate declared by the station, using a simulation based estimator based on the station occupancy rate and state, the charging station comprising:

• at least one charging unit enabling the charging of electric vehicles and keeping track of the charged vehicle information, the charging time, and the charging duration length recording,
• a waiting area at the station having sections where vehicles can wait and having a guidance signboard,
• at least one kiosk located at the station entrance, with a screen, wireless data communication unit and processor on which the user can interact with his smart device, and adapted to receive the user's high priority or low priority service request by recognizing or communication with the user, a tracking monitor adapted to communicate with the charging unit, guidance signboard, and kiosk in a wired or wireless fashion, to track the events and time, track the entry, exit, service start and end times of all vehicles according to the data received from the charging unit, to track the event related to the vehicle when a vehicle enters or exits the station, and transmit thereof to the controller;
• a controller comprising a decision maker and a system module, and adapted to take action with the event reported by the tracking monitor, to decide whether the charging unit which becomes idle when the vehicle leaves the station would be assigned a high priority or low priority vehicle class, and to decide where to direct the incoming vehicle when a new vehicle arrives at the station,
• the decision maker adapted to take action first when the controller works, to act differently depending on the vehicle arrival or departure event that caused the controller to operate,
• in case the event is a vehicle arrival and there is an idle charging unit at the station, to direct the vehicle to the charging unit, and if there is no idle charging unit, to direct the vehicle to the waiting area,
• in case the event that occurs is a vehicle leaving the station, and if there is only one class vehicle in the waiting area, to direct the first vehicle of that class to the idle charging unit, and in case there are vehicles of both classes in the waiting area, to determine which class the idle charging unit will be assigned to,
• the system module adapted to estimate the effect of the decisions made by the decision maker on the average waiting times of the high priority and low priority vehicles in the station by being run by the decision maker for different scenarios, and to enable the decision maker to make their decisions based on the said prediction results.
