Integrating ISO15118 standard to implement V1G and to unlock Energy Flexibility in the automotive

The protection of the planet and particularly the control of climatic alterations is a theme that is becoming more and more neuralgic in today’s society and is the reason that pushes for new developments and changes in everyday activities. Since vehicles emit CO2 and many other greenhouse gases, being one of the major pollution causes all around the world, electric vehicles are becoming more and more crucial to partially solve the climatic change problem. The electric vehicles and all the e-mobility panorama are in their first years, therefore it is all evolving fast, trying to accomplish user and energy needs. The objective of this thesis is to integrate ISO15118 to create a Proof of Concept (PoC) focused on the V1G and the unlocking of energy flexibility in the automotive. The ISO15118 standard main benefits are the improvement of the quality of the user journey during the charging process with the new feature called "Plug & Charge", which allows the user to start the electric vehicle charging just by plugging the cable in, without the use of any easy-to-lose cards; the scheduling of the charging process based on the e-mobility needs and the renewable energy availability, integrating "smart charging" and "energy flexibility"; stronger data security with TLS 1.2 protocol, ensuring confidentiality, data integrity, and authenticity. The PoC implements the communication between the electric vehicle and the charging station, following the ISO15118 requirements, with the implementation of the open-source protocol stack "RiseV2G". The graphical user interfaces are implemented with the use of two tablets (one for the electric vehicle and one for the charge point), in order to allow the user to express his/her preferences about the payment option and the charging profile. The electric vehicle and the electric vehicle supply equipment operations regarding the charging communication are implemented with the use of two micro-computers and two tablets. An accurate testing procedure has been made to validate the PoC behavior in all the possible use cases.
