Data exchange of electric vehicle charging station with the environment

U ovom radu opisana je razmjena podataka između punionice i ostalih sudionika u punjenju električnog vozila. Električna vozila zahtijevaju veću količinu energije od kućanstva (do 100kWh) te sadašnja naponska mreža može imati poteškoća s punjenjem velike količine električnih vozila istovremeno. Zato je potrebna komunikacija između sudionika u sustavu punjenja kako bi se postigla najveća učinkovitost sustava. Veliku ulogu u svemu ima V2X koncept koji treba upravljati tokom energije unutar sustava. Razmjenjivanje poruka se regulira standardima i protokolima (CAN, OCPP, ISO/IEC 15118) između pojedinih dijelova sustava (punionice, električnog vozila, naponske mreže, brojila, servisa).This paper describes the data exchange between the charging station and other participants in charging the electric vehicle. Electric vehicles require a larger amount of energy than housholds (up to 100kWh) and the current power grid may have difficulty charging a large amount of electric vehicles at the same time. Therefore, communication between participians in the charging system is required to achive maximum system efficiency. The V2X concept plays an important role in all of this because it needs to operate the energy flow within the system. The exchange of messages is regulated by standards and protocols (CAN, OCPP, ISO/IEC 15118) between individual parts of the system (charging station, electric vehicle, power supply network, meters, service)
