Potencializando a mobilidade sustentável: projeto de estações de recarga de veículos elétricos com comunicação OCPP

Abstract

The work focuses on the implementation of a communication system based on the OCPP (Open Charge Point Protocol) 1.6J standard in electric vehicle charging stations. The objective is to develop a complete communication setup, from the vehicle to the server, and explore the OCPP 1.6J messages to enable efficient communication between the systems. The study concentrates on creating a circuit with an ESP32 on a protoboard for reading and generating the Control Pilot signal, used to communicate with the electric vehicle and verify its correct operation in response to CSMS commands. Additionally, a CSMS server was implemented capable of communicating with the EVSE (Electric Vehicle Supply Equipment), cataloging, and storing information about the charging process and the charging power reported by the EVSE. During the implementation, ready-made solutions such as SteVe and the Arduino OCPP library were used, which were fundamental to the success of the project. The solution was fully functional, and the developed EVSE can communicate correctly with the CSMS and the EV. The charging system implementation proved to be straightforward and efficient, considering the technical standards established for charging station implementation. The project highlights the entire process of circuit development for electric vehicle communication and power measurement, describing the project and its results. In summary, the work emphasizes the potential of OCPP-based solutions to drive sustainable mobility through the construction of intelligent electric vehicle charging stations aligned with international standards. The developed prototype provides a solid foundation for future studies and implementations in the field of electric vehicle charging.
