Resumen
The transport sector has an important role in the development of the economy, the growth
of this market, however, has always been side by side with the productive chains of fossil fuels through vehicles with internal combustion engines. However, due to the increase
in world awareness about the pollution caused by the consumption of fossil fuels and the
drop in the value of batteries, electric vehicles have become an option to be adopted to
reduce the emission of these polluting gases. However, in order to electrify the car fleet, it
is necessary to develop the basic infrastructure that supplies energy to these vehicles, for
this reason, the installation of charging stations is a key point for the adoption of this new
technology. This dissertation presents a methodology for intelligent management of electric vehicle chargers using the OCPP 1.6j protocol. The dissertation was developed in two
stages, the first stage in a simulated environment, where the services and architecture of
the OCPP server were created, in this stage tests and validations of the functionalities that
the protocol makes available were also carried out. The second step is related to the integration in real chargers, where the first charger was a single-phase model of slow charging
in alternating current. The next integrated chargers were the fast chargers that constitute
the first electroway in Rio Grande do Sul that connects the center of the state to the coast.
The Framework was developed to support different agents in the system, where each agent
can designate limitations on the use and power of the charging stations. The case study
showed a good management of the charging stations, in all, the system was implemented
in 9 chargers of different models. Operating daily and in real time, the system received
essential feedback for the creation of new functionalities that increased user support and
control of charging station operators.
