Electric Vehicles Charging Reservation Based on OCPP

Management of charge of electrical vehicles can be effectively integrated in a Vehicle To Grid system. This regulated operation is described in the OCPP standard. In this work we propose an extension of the OCPP protocol to the reservation phase. The user can reserve the charging station in advance negotiating the parameters for the charge: initial time, duration, location, price, percentage of final charge, power required. We developed an application for Android smartphone affords to the customer to completely control the process of reservation and charge in all its phases: authentication to the service, choice of the charge parameters, monitoring of the charge and payment.
