20.500.12556/RUL-119081 Modifikacija polnilne postaje za električna vozila OpenEVSE Modification of the OpenEVSE electric vehicle charging station Namen diplomske naloge je predstaviti postopek načrtovanja in realizacije predelave polnilnice za električna vozila na način, ki je cenovno ugoden in izvedljiv brez uporabe specializiranih orodji. Kot osnova za predelavo polnilnice je bila uporabljena obstoječa polnilna postaja OpenEVSE advanced v5, ki je komercialna polnilna postaja projekta OpenEVSE. Načrti sestavnih delov polnilnice in programska oprema polnilnice so odprtokodni in na voljo javnosti pod pogoji splošne javne licence GNU. Predelava vključuje spreminjanje obstoječe programske opreme v jeziku C++, načrtovanje tiskanih vezij in njihovo umestitev v celoten polnilni sistem, primeren za uporabo v domovih in na javnih mestih. V okviru nadgradnje polnilnice je bil spremenjen način polnjenja v polnjenje s trofaznim tokom, s čimer je dosežen krajši čas polnjenja. Polnilnici je bil nadgrajen tudi način merjenja energije, kjer se električni tok meri na vseh treh električnih fazah. Zraven polnilnega vezja je bil dodan tudi računalnik Raspberry Pi, ki komunicira z polnilno postajo in omogoča njen nadzor in krmiljenje preko žične internetne povezave. Postavljena je bila tudi osnovna strežniška infrastruktura, ki polnilnico uskladi s komunikacijskim protokolom OCPP The purpose of this thesis is to present the process of planning and implementing a modification of a charging station for electric vehicles in a way that is both affordable and feasible without the use of specialized tools. For the basis of the modification, the OpenEVSE Advanced v5 charging station was used. This is a comercial open source charging station designed by the OpenEVSE project. The schematics and software of the charging station are all available under the terms of the GNU general public license. The modifications include the changing of existing C++ software, the design of custom printed circuit boards and their implementation into a charging station, suitable for use in both private and public places. The charging station was converted to accommodate three-phase charging, with which shorter charging times were achieved. The stations current measurement system was consequently upgraded to allow energy measurement on all three electric phases. A Raspberry Pi computer was also added to allow remote monitoring and control of the charging station over a wired internet connection. The basic network infrastructure was also laid-out for the compliance of the charging station with the OCPP protocol. polnilna postaja električno vozilo programiranje mikrokrmilnik tiskana vezja Linux charging station electric vehicle programing printed circuit boards microcontroler Linux true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2020-09-02 14:30:18 2020-09-02 14:30:25 2022-08-31 03:51:17 0000-00-00 00:00:00 2020 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 51461 Kramzar_Ales_-_Modifikacija_polnilne_postaje_za_elektricna_vozila_OpenEVSE.pdf Kramzar_Ales_-_Modifikacija_polnilne_postaje_za_elektricna_vozila_OpenEVSE.pdf 1 9DD0A15F575B6E541E92E6C4A89F5C83 52299ac70dead623d444e583046f9bf4c01e6041ca8beb65a0cfb6c2e98c8509 ba660f30-a1b9-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=133737 Fakulteta za elektrotehniko 0 0 0
