Abstract

V diplomskem delu je predstavljen postopek načrtovanja in realizacije testerja polnilnic za električna vozila (EVSE), ki preverja delovanje polnilnih postaj, saj morajo biti narejene v skladu s standardi in varnostnimi predpisi, ki jih standardi predpisujejo. Poleg preverjanja delovanja polnilne postaje tester EVSE preverja tudi odzive postaje na morebitne napake, ki so lahko nevarne za uporabnika in okolje. Za izdelavo testerja se je podjetje odločilo, ker se število električnih vozil in polnilnih postaj v svetu hitro povečuje. Razvoj testerja je potekal po sklopih (komunikacija, simulator baterije, krmilno vezje, razvoj uporabniškega vmesnika). Za realizacijo projekta sta uporabljeni dve različni polnilni postaji: - EVSE visokocenovnega razreda, ki izvaja in preverja po vseh predpisih in zahtevah, - EVSE nizkocenovnega razreda, ki določene predpise ignorira. Različne polnilne postaje smo uporabili predvsem zato, da lahko primerjamo odzive in realizacijo oz. razvoj projekta prilagodimo odzivom. Med razvojem smo napravo večkrat preizkusili tudi na javnih polnilnih postajah ter jo ustrezno prilagodili rezultatom preizkusa. Tester ni popolnoma zaključen. Uspelo nam je: vzpostaviti polnjenje, izvajati manjše meritve (merjenje napetosti polnjenja in napetosti baterije), vzpostaviti nadzor nad komunikacijo med vozilom in polnilno postajo ter spreminjati polnilne parametre. Potrebno je avtomatizirati izvajanje simulacij/meritev in napravi dodati merilnike toka in napetosti, ki jih potrebujemo pri posamezni meritvi ali simulaciji.

Secondary title: Testing of electric vehicle supply equipment
Secondary abstract: In this work, developing and testing of electric vehicle supply equipment (EVSE) tester is presented. Electric vehicle chargers must comply with standards and safety regulations that these standards impose. Among correct charging behaviour, tester also checks charger's response to various errors that might occur, which are dangerous to humans or environment. With ever growing number of electric vehicles, we decided to develop and build tester for charging stations. The development of the tester took place in stages: communication, battery simulator, control circuit, user interface. Two different charging stations were used with our project: a high-end class EVSE that implements and verifies requirements and regulations. A low-cost one that performs bare minimum and ignores several fault conditions. We used different chargers mainly for comparing their responses and we could adapt the project development. During development, our tester was tested several times on public charging stations and adjusted/improved based on test results. Tester itself is not completed entirely, but we managed to complete: Measuring charging voltage and battery voltage, establish communication and control between electric vehicle (our tester) and charging station and monitoring parameters. For later work it is necessary to automate simulations/measurements and add current and voltage meters to the device, which are needed for an individual measurement or simulation.
