I-Evolution ye-EV Charging Protocols: Ukuhlaziywa Okuqhathanisayo kwe-OCPP 1.6 ne-OCPP 2.0

Ukukhula okusheshayo kweIngqalasizinda yokushaja imoto kagesiuye wadinga izimiso zokuxhumana ezimisiwe ukuze kuqinisekiswe ukusebenzisana phakathi kweziteshi zokushaja ze-EV kanye nezinhlelo zokuphatha ezimaphakathi. Phakathi kwalezi zimiso, i-OCPP (I-Open Charge Point Protocol) iye yavela njengophawu lomhlaba wonke. Lesi sihloko sihlola umehluko oyinhloko phakathi kwe-OCPP 1.6 ne-OCPP 2.0, sigxile kumthelela wazo kubuchwepheshe Beshaja ye-EV, ukusebenza kahle kokushaja, nokuhlanganiswa namazinga esimanje njenge-CCS (Isistimu Yokushaja Ehlanganisiwe), i-GB/T, nokushaja okusheshayo kwe-DC.

1. Amamodeli Wokwakhiwa Kwephrothokholi kanye Nezokuxhumana

I-OCPP 1.6, eyethulwe ngo-2017, isekela kokubili amafomethi e-SOAP (ngaphezu kwe-HTTP) kanye ne-JSON (ngaphezu kwe-WebSocket), okuvumela ukuxhumana okuvumelana nezimo phakathiAmashaja e-Wallboxkanye nezinhlelo ezimaphakathi. Imodeli yayo yemiyalezo engavumelaniyo ivumelaIziteshi zokushaja ze-EVukuphatha imisebenzi efana nokuqinisekisa, ukuphathwa kokwenziwe, nezibuyekezo ze-firmware.

I-OCPP 2.0.1(2020), i-iteration yakamuva, yamukela i-architecture eqine kakhulu enokuphepha okuthuthukisiwe. Igunyaza i-HTTPS yokuxhumana okubethelwe futhi yethula izitifiketi zedijithali zokuqinisekisa idivayisi, ibhekana nobungozi kuzinguqulo zangaphambilini. Lokhu kuthuthukisa kubalulekileIziteshi zokushaja okusheshayo ze-DC, lapho ubuqotho bedatha nokuqapha kwesikhathi sangempela kubaluleke kakhulu.

2. Ukushaja okuhlakaniphile kanye nokuphathwa kwamandla

Isici esivelele se-OCPP 2.0 ukuthuthuka kwayoUkushaja okuhlakaniphileamakhono. Ngokungafani ne-OCPP 1.6, enikeza ukulinganisa okuyisisekelo komthwalo, i-OCPP 2.0 ihlanganisa amasistimu okuphatha amandla ashukumisayo (EMS) futhi isekela ubuchwepheshe be-Vehicle-to-Grid (V2G). Lokhu kuvumelaAmashaja we-EVukulungisa izilinganiso zokushaja ngokusekelwe esidingweni segridi noma ukutholakala kwamandla avuselelekayo, ukuthuthukisa ukusatshalaliswa kwamandla kuzo zonke Iziteshi zokushaja ze-EV.

Isibonelo, Ishaja ye-Wallbox esebenzisa i-OCPP 2.0 ingakwazi ukubeka phambili ukushaja phakathi namahora okungasebenzi kakhulu noma ukunciphisa amandla ngesikhathi sokuminyana kwegridi, ithuthukise ukusebenza kahle kokubili kokuhlala nokuthengisa.Izilungiselelo zokushaja imoto kagesi.

3. Ukuphepha Nokuhambisana

Nakuba i-OCPP 1.6 incike ezindleleni zokuqinisekisa eziyisisekelo, i-OCPP 2.0 yethula ukubethela ngasemaphethelweni kanye namasiginesha edijithali ukuze kubuyekezwe i-firmware, inciphise izingozi ezifana nokufinyelela okungagunyaziwe noma ukuphazamisa. Lokhu kubaluleke kakhuluIziteshi ezithobela i-CCS ne-GB/T, esisingatha idatha yomsebenzisi ebucayi kanye nemisebenzi ye-DC enamandla amakhulu.

4. Amamodeli Wedatha Athuthukisiwe Nokusebenza

I-OCPP 2.0inweba amamodeli wedatha ukusekela izimo zokushaja eziyinkimbinkimbi. Yethula izinhlobo zemilayezo emisha yokuxilongwa, ukuphathwa kokubhukha, kanye nokubikwa kwesimo sesikhathi sangempela, okuvumela ukulawula kwembudumbudu phezuIziteshi zokushaja ze-EV. Isibonelo, opharetha bangakwazi ukuhlonza amaphutha bekudeAmayunithi okushaja okusheshayo e-DCnoma ubuyekeze izilungiselelo zamashaja e-Wallbox ngaphandle kokungenelela endaweni.

Ngokuphambene, i-OCPP 1.6 ayinakho ukwesekwa komdabu kwe-ISO 15118 (I-plug & Charge), umkhawulo obhekiswe ku-OCPP 2.0 ngokuhlanganiswa okungenamthungo naleli zinga. Le ntuthuko yenza ukuqinisekiswa komsebenzisi kube lula eziteshini ze-CCS kanye ne-GB/T, ivumela ukuzizwisa "kwe-plug-and-charge".

5. Ukuhambisana Nokwamukelwa Kwemakethe

I-OCPP 1.6 isalokhu yamukelwa kabanzi ngenxa yokuvuthwa kwayo nokuhambisana nezinhlelo zefa, okuhlanganisa amanethiwekhi asekelwe ku-GB/T e-China. Nokho, ukungahambisani kwe-OCPP 2.0 nezinguqulo zangaphambili kubangela izinselele zokuthuthukiswa, ngaphandle kwezici zayo eziphakeme njengosekelo lwe-V2G nokulinganisa okuthuthukisiwe komthwalo.

Isiphetho

Ushintsho olusuka ku-OCPP 1.6 ukuya ku-OCPP 2.0 luphawula ukweqa okubalulekile kubuchwepheshe bokushaja kwezimoto zikagesi, obuqhutshwa izimfuno zokuphepha, ukusebenzisana, nokuphathwa kwamandla okukhaliphile. Nakuba i-OCPP 1.6 yanela ukusebenza kwe-EV Charger eyisisekelo, i-OCPP 2.0 ibalulekile ekuqinisekiseni iziteshi zokushaja ze-EV zokuqinisekisa ngokuzayo, ikakhulukazi lezo ezisekelayo.Ukushaja okusheshayo kwe-DC, CCS, kanye ne-V2G. Njengoba imboni ithuthuka, ukwamukela i-OCPP 2.0 kuzobaluleka kakhulu ukuze kuhambisane namazinga omhlaba kanye nokuthuthukisa ulwazi lwabasebenzisi kuma-Wallbox Charger kanye nezindawo zokushaja zomphakathi.
