Uphuhliso lweeProtokholi zokutshaja ze-EV: Uhlalutyo oluQhathaniswayo lwe-OCPP 1.6 kunye ne-OCPP 2.0

Ukukhula ngokukhawuleza kweIsiseko sokutshaja iimoto zombanekuye kwayimfuneko ukuba kubekho iiprotokholi zonxibelelwano ezisemgangathweni ukuqinisekisa ukusebenzisana phakathi kweZitishi zokuTshaja ze-EV kunye neenkqubo zolawulo oluphakathi. Phakathi kwezi protokholi, i-OCPP (i-Open Charge Point Protocol) iye yavela njengomgangatho wehlabathi. Eli nqaku liphonononga umahluko ophambili phakathi kwe-OCPP 1.6 kunye ne-OCPP 2.0, ligxile kwimpembelelo yazo kubuchwepheshe be-EV Charger, ukusebenza kakuhle kokutshaja, kunye nokuhlanganiswa nemigangatho yanamhlanje efana ne-CCS (iNkqubo yokuTshaja eDibeneyo), i-GB/T, kunye nokutshaja ngokukhawuleza kwe-DC.

1. Iimodeli zoYilo lweProtocol kunye noNxibelelwano

I-OCPP 1.6, eyaziswa ngo-2017, ixhasa zombini iifomathi ze-SOAP (ngaphezulu kwe-HTTP) kunye ne-JSON (ngaphezulu kweWebSocket), ivumela unxibelelwano oluguquguqukayo phakathiIitshaja zeWallboxkunye neenkqubo eziphambili. Imodeli yayo yemiyalezo engahambelaniyo ivumelaIzikhululo zokutshaja ze-EVukuphatha imisebenzi efana nokuqinisekisa, ulawulo lwentengiselwano, kunye nohlaziyo lwe-firmware.

I-OCPP 2.0.1(2020), olu hlaziyo lwamva nje, lusebenzisa uyilo oluqinileyo olunokhuseleko oluphuculweyo. Luyalela i-HTTPS yonxibelelwano olufihliweyo kwaye luzisa izatifikethi zedijithali zokuqinisekiswa kwesixhobo, lujongana nobuthathaka kwiinguqulelo zangaphambili. Olu phuculo lubalulekile kwiIzikhululo zokutshaja ngokukhawuleza zeDC, apho ukuthembeka kwedatha kunye nokubeka esweni ngexesha langempela kubaluleke kakhulu.

2. Ukutshaja ngobuchule kunye noLawulo lwaMandla

Uphawu olubalaseleyo lwe-OCPP 2.0 kukuba iphucukileUkutshaja okuKhawulezayoizakhono. Ngokungafaniyo ne-OCPP 1.6, enika ukulinganisela umthwalo okusisiseko, i-OCPP 2.0 idibanisa iinkqubo zolawulo lwamandla aguqukayo (i-EMS) kwaye ixhasa ubuchwepheshe beVehicle-to-Grid (V2G). Oku kuvumelaIitshaja ze-EVukulungisa amazinga okutshaja ngokusekelwe kwimfuno yegridi okanye ukufumaneka kwamandla avuselelekayo, ukuphucula ukusasazwa kwamandla kuzo zonke izikhululo zokutshaja ze-EV.

Umzekelo, iWallbox Charger esebenzisa i-OCPP 2.0 inokwenza ukutshaja kube yinto ephambili ngexesha elingengomsebenzi okanye inciphise umbane ngexesha lokuxinana kwegridi, nto leyo ephucula ukusebenza kakuhle kwezindlu kunye nezorhwebo.Ukuseta ukutshaja iimoto zombane.

3. Ukhuseleko kunye nokuThotyelwa kweMithetho

Nangona i-OCPP 1.6 ixhomekeke kwiindlela ezisisiseko zokuqinisekisa, i-OCPP 2.0 yazisa ukubethela ukusuka ekuqaleni ukuya ekupheleni kunye notyikityo lwedijithali lokuhlaziya i-firmware, ukunciphisa iingozi ezifana nokufikelela okungagunyaziswanga okanye ukuphazamisa. Oku kubaluleke kakhulu kwiIzikhululo ezithobela imithetho ye-CCS kunye ne-GB/T, eziphatha idatha yomsebenzisi ebucayi kunye neentengiselwano zeDC ezinamandla aphezulu.

4. Iimodeli zeDatha eziphuculweyo kunye nokusebenza kakuhle

I-OCPP 2.0yandisa iimodeli zedatha ukuxhasa iimeko zokutshaja ezintsonkothileyo. Yazisa iintlobo ezintsha zemiyalezo yokuxilongwa, ulawulo lokubhukisha, kunye nengxelo yesimo sexesha langempela, ivumela ulawulo olupheleleyo phezuIzikhululo zokutshaja ze-EVUmzekelo, abaqhubi banokuchonga iimpazamo bekudeIiyunithi zokutshaja ngokukhawuleza ze-DCokanye uhlaziye uqwalaselo lweeWallbox Chargers ngaphandle kokungenelela kwindawo.

Ngokwahlukileyo koko, i-OCPP 1.6 ayinayo inkxaso yendalo ye-ISO 15118 (iPlug & Charge), umda ojongwayo kwi-OCPP 2.0 ngokudibanisa okungenamthungo nalo mgangatho. Olu phuculo lwenza lula ukuqinisekiswa komsebenzisi kwizikhululo ze-CCS kunye ne-GB/T, nto leyo evumela amava "okufaka iplagi kunye netshaja".

5. Ukuhambelana kunye nokwamkelwa kweMarike

I-OCPP 1.6 isasetyenziswa kakhulu ngenxa yokuvuthwa kwayo kunye nokuhambelana kwayo neenkqubo zakudala, kuquka neenethiwekhi ezisekelwe kwi-GB/T eTshayina. Nangona kunjalo, ukungahambelani kwe-OCPP 2.0 neenguqulelo zangaphambili kudala imingeni yokuphucula, nangona ineempawu ezibalaseleyo ezifana nenkxaso ye-V2G kunye nokulinganisela umthwalo okuphambili.

Isiphelo

Utshintsho oluvela kwi-OCPP 1.6 ukuya kwi-OCPP 2.0 lubonisa inqanaba elikhulu kubuchwepheshe bokutshaja iimoto zombane, oluqhutywa ziimfuno zokhuseleko, ukusebenzisana, kunye nolawulo lwamandla olukrelekrele. Nangona i-OCPP 1.6 yanele kwimisebenzi esisiseko yetshaja ye-EV, i-OCPP 2.0 ibalulekile kwizikhululo zokutshaja ze-EV ezikhusela kwixesha elizayo, ingakumbi ezo zixhasayo.Ukutshaja ngokukhawuleza kwe-DC, i-CCS, kunye ne-V2G. Njengoko eli shishini liqhubeka likhula, ukwamkela i-OCPP 2.0 kuya kuba yinto ebalulekileyo ekuhambelaneni nemigangatho yehlabathi kunye nokuphucula amava abasebenzisi kwiWallbox Chargers nakwiindawo zokutshaja zikawonke-wonke.
