Ukuvela Kwezinqubo Zokushaja ze-EV: Ukuhlaziywa Okuqhathanisayo kwe-OCPP 1.6 kanye ne-OCPP 2.0

Ukukhula okusheshayo kweIngqalasizinda Yokushaja Imoto Kagesikuye kwadingeka izinqubo zokuxhumana ezijwayelekile ukuqinisekisa ukusebenzisana phakathi kweZiteshi Zokushaja ze-EV kanye nezinhlelo zokuphatha eziphakathi. Phakathi kwalezi zinqubo, i-OCPP (i-Open Charge Point Protocol) ivele njengesilinganiso somhlaba wonke. Lesi sihloko sihlola umehluko obalulekile phakathi kwe-OCPP 1.6 kanye ne-OCPP 2.0, sigxile emthonjeni wazo kubuchwepheshe be-EV Charger, ukusebenza kahle kokushaja, kanye nokuhlanganiswa nezindinganiso zesimanje njenge-CCS (i-Combined Charging System), i-GB/T, kanye nokushaja okusheshayo kwe-DC.

1. Amamodeli Okwakha Iphrothokholi Nokuxhumana

I-OCPP 1.6, eyethulwa ngo-2017, isekela kokubili amafomethi e-SOAP (ngaphezu kwe-HTTP) kanye ne-JSON (ngaphezu kwe-WebSocket), okuvumela ukuxhumana okuguquguqukayo phakathiAmashaja e-Wallboxkanye nezinhlelo eziphakathi. Imodeli yayo yokuthumela imiyalezo engahambisani ivumelaIziteshi Zokushaja I-EVukuphatha imisebenzi efana nokuqinisekisa, ukuphathwa kokuthengiselana, kanye nezibuyekezo ze-firmware.

I-OCPP 2.0.1(2020), okuwukuphindaphindwa kwakamuva, kusebenzisa ukwakheka okuqinile okunokuphepha okuthuthukisiwe. Kugunyaza i-HTTPS yokuxhumana okubethelwe futhi kwethula izitifiketi zedijithali zokuqinisekiswa kwedivayisi, kubhekana nobuthakathaka ezinguqulweni zangaphambilini. Lokhu kuthuthukiswa kubalulekile ku-Iziteshi zokushaja okusheshayo ze-DC, lapho ubuqotho bedatha kanye nokuqapha ngesikhathi sangempela kubaluleke kakhulu.

2. Ukushaja Okuhlakaniphile Nokuphathwa Kwamandla

Isici esivelele se-OCPP 2.0 ukuthi ithuthukisiweUkushaja Okuhlakaniphileamakhono. Ngokungafani ne-OCPP 1.6, enikeza ukulinganisela umthwalo okuyisisekelo, i-OCPP 2.0 ihlanganisa izinhlelo zokuphatha amandla aguqukayo (i-EMS) futhi isekela ubuchwepheshe be-Vehicle-to-Grid (V2G). Lokhu kuvumelaAmashaja e-EVukulungisa amazinga okushaja ngokusekelwe ekudingweni kwegridi noma ukutholakala kwamandla avuselelekayo, ukuthuthukisa ukusatshalaliswa kwamandla kuzo zonke iziteshi zokushaja ze-EV.

Isibonelo, i-Wallbox Charger esebenzisa i-OCPP 2.0 ingenza ukushaja kube yinto ebaluleke kakhulu ngesikhathi esingekho ngesikhathi sokusebenza kakhulu noma inciphise amandla ngesikhathi sokuminyana kwegridi, ithuthukise ukusebenza kahle kokubili kwezindlu kanye nezentengiselwano.Ukusetha ukushaja imoto kagesi.

3. Ukuphepha Nokuthobela Imithetho

Nakuba i-OCPP 1.6 ithembele ezindleleni eziyisisekelo zokuqinisekisa, i-OCPP 2.0 yethula ukubethela kusukela ekuqaleni kuya ekugcineni kanye nokusayina kwedijithali kwezibuyekezo ze-firmware, okunciphisa izingozi ezifana nokufinyelela okungagunyaziwe noma ukuphazanyiswa. Lokhu kubaluleke kakhulu ku-Iziteshi ezithobela imithetho ye-CCS kanye ne-GB/T, ephatha idatha yomsebenzisi ebucayi kanye nokuthengiselana kwe-DC okunamandla amakhulu.

4. Amamodeli Edatha Athuthukisiwe Nokusebenza

I-OCPP 2.0yandisa amamodeli wedatha ukuze isekele izimo zokushaja eziyinkimbinkimbi. Yethula izinhlobo ezintsha zemiyalezo zokuxilonga, ukuphathwa kokubhukha, kanye nokubika isimo ngesikhathi sangempela, okuvumela ukulawula okuningiliziweIziteshi Zokushaja I-EVIsibonelo, opharetha bangahlonza amaphutha bekudeAmayunithi okushaja okusheshayo e-DCnoma ubuyekeze ukucushwa kwama-Wallbox Chargers ngaphandle kokungenelela okukhona.

Ngokuphambene nalokho, i-OCPP 1.6 ayinalo ukwesekwa kwemvelo kwe-ISO 15118 (i-Plug & Charge), okuwumkhawulo obhekwe ku-OCPP 2.0 ngokuhlanganiswa okungenamthungo nale nqubo. Lokhu kuthuthuka kwenza kube lula ukuqinisekiswa komsebenzisi eziteshini ze-CCS kanye ne-GB/T, okuvumela okuhlangenwe nakho "kokuxhuma nokushaja".

5. Ukuhambisana kanye nokwamukelwa kwemakethe

I-OCPP 1.6 isasetshenziswa kabanzi ngenxa yokuvuthwa kwayo kanye nokuhambisana kwayo nezinhlelo ezindala, okuhlanganisa namanethiwekhi asekelwe ku-GB/T eShayina. Kodwa-ke, ukungahambelani kwe-OCPP 2.0 nezinguqulo zangaphambilini kudala izinselele zokuthuthukiswa, naphezu kwezici zayo ezinhle njengokusekela i-V2G kanye nokulinganisela umthwalo okuthuthukisiwe.

Isiphetho

Ushintsho oluvela ku-OCPP 1.6 luye ku-OCPP 2.0 luphawula inqubekela phambili enkulu kubuchwepheshe bokushaja izimoto zikagesi, obuqhutshwa yizidingo zokuphepha, ukusebenzisana, kanye nokuphathwa kwamandla okuhlakaniphile. Nakuba i-OCPP 1.6 yanele ekusebenzeni okuyisisekelo kweshaja ye-EV, i-OCPP 2.0 ibalulekile eziteshini zokushaja ze-EV ezivikela esikhathini esizayo, ikakhulukazi lezo ezisekelayoUkushaja okusheshayo kwe-DC, i-CCS, kanye ne-V2G. Njengoba imboni ithuthuka, ukwamukela i-OCPP 2.0 kuzobaluleka kakhulu ekuhambisaneni nezindinganiso zomhlaba wonke kanye nokuthuthukisa okuhlangenwe nakho kwabasebenzisi ku-Wallbox Chargers kanye nezindawo zokushaja zomphakathi.

Ukuze uthole imininingwane eyengeziwe mayelana nezincazelo zephrothokholi>>>.
