I-Evolution ye-EV Charging Protocols: Uhlalutyo lokuthelekisa lwe-OCPP 1.6 kunye ne-OCPP 2.0

Ukukhula ngokukhawuleza kweIziseko ezingundoqo zokuTjaja iiMoto zoMbaneuye wafuna imigaqo yonxibelelwano esemgangathweni ukuqinisekisa ukusebenzisana phakathi kweZitishi zokuTshaja ze-EV kunye neenkqubo zolawulo oluphakathi. Phakathi kwezi prothokholi, i-OCPP (iProtokholi yeNdawo yokuTyala eVulekileyo) iye yavela njengophawu lwehlabathi jikelele. Eli nqaku liphonononga ukungafani okuphambili phakathi kwe-OCPP 1.6 kunye ne-OCPP 2.0, kugxininise kwimpembelelo yabo kwi-teknoloji ye-EV Charger, ukusebenza kakuhle kokutshaja, kunye nokudibanisa nemigangatho yanamhlanje efana ne-CCS (iNkqubo yokuTshaja eDityanisiweyo), i-GB / T, kunye ne-DC yokutshaja ngokukhawuleza.

1. Uyilo lweProtokholi kunye neeModeli zoNxibelelwano

I-OCPP 1.6, eyaziswa kwi-2017, ixhasa zombini i-SOAP (ngaphaya kwe-HTTP) kunye ne-JSON (ngaphezu kwe-WebSocket) iifomati, eyenza unxibelelwano oluguquguqukayo phakathiIitshaja zebhokisi yodongakunye neenkqubo eziphambili. Imodeli yayo yokuthumela imiyalezo esynchronous ivumelaIzitishi zokutshaja ze-EVukusingatha imisebenzi efana nokuqinisekisa, ulawulo lwentengiselwano, kunye nohlaziyo lwe-firmware.

I-OCPP 2.0.1(2020), i-iteration yamva nje, yamkele uyilo olomelele ngakumbi ngokhuseleko olomeleziweyo. Igunyazisa i-HTTPS yonxibelelwano oluntsonkothileyo kwaye yazisa iziqinisekiso zedijithali zoqinisekiso lwesixhobo, ijongana nobuthathaka kwiinguqulelo zangaphambili. Olu hlaziyo lubalulekileizikhululo zokutshaja ngokukhawuleza kwe-DC, apho ukuthembeka kwedatha kunye nokubeka iliso ngexesha langempela kubaluleke kakhulu.

2. I-Smart Charging kunye noLawulo lwaMandla

Inqaku elibalaseleyo le-OCPP 2.0 kukuqhubela phambili kwayoUkutshaja ngobuchuleizakhono. Ngokungafani ne-OCPP 1.6, enika ukulinganisa okusisiseko, i-OCPP 2.0 idibanisa iinkqubo zolawulo lwamandla ashukumisayo (EMS) kwaye ixhasa i-Vehicle-to-Grid (V2G) iteknoloji. Oku kuvumelaIitshaja ze-EVukulungelelanisa amaxabiso okutshaja ngokusekelwe kwimfuno yegridi okanye ukufumaneka kwamandla ahlaziyekayo, ukwandisa ukuhanjiswa kwamandla kuzo zonke iZikhululo zokuTshaja ze-EV.

Umzekelo, itshaja yeWallbox isebenzisa i-OCPP 2.0 inokubeka phambili ukutshaja ngexesha leeyure ezingasebenziyo okanye ukunciphisa amandla ngexesha lokuxinana kwegridi, iphucula ukusebenza kakuhle kokuhlala kunye nezorhwebo.Izicwangciso zokuTshaja kwiMoto yoMbane.

3. Ukhuseleko kunye nokuThobela

Ngelixa i-OCPP 1.6 ixhomekeke kwiindlela zokuqinisekisa ezisisiseko, i-OCPP 2.0 yazisa uguqulelo olusekugqibeleni ukuya esiphelweni kunye neesayino zedijithali zohlaziyo lwe-firmware, ukunciphisa imingcipheko efana nokufikelela okungagunyaziswanga okanye ukuphazamisa. Oku kubaluleke kakhuluI-CCS kunye ne-GB/T-ethobela izikhululo, ephatha idatha yomsebenzisi enovakalelo kunye nentengiselwano ephezulu yamandla eDC.

4. Iimodeli zeDatha eziPhuculweyo kunye nokuSebenza

I-OCPP 2.0yandisa imifuziselo yedatha ukuxhasa iimeko zokutshaja ezinzima. Yazisa iintlobo zemiyalezo emitsha yoxilongo, ulawulo logcino, kunye nengxelo yexesha lokwenyani, eyenza ulawulo lwegranular ngaphezulu.Izitishi zokutshaja ze-EV. Ngokomzekelo, abaqhubi banokufumanisa iimpazamo bekudeIiyunithi zokutshaja ngokukhawuleza kwe-DCokanye uhlaziywe ulungelelwaniso lweeTshaja zeWallbox ngaphandle kokungenelela kwindawo.

Ngokwahlukileyo, i-OCPP 1.6 ayinayo inkxaso yendalo ye-ISO 15118 (Plug & Charge), umda obhekiswe kwi-OCPP 2.0 ngokudibanisa ngokungenamthungo kunye nalo mgangatho. Le nkqubela phambili yenza lula ukuqinisekiswa komsebenzisi kwizikhululo zeCCS kunye ne-GB/T, ivumela amava e-“plug-and-charge”.

5. Ukuhambelana kunye nokwamkelwa kweMarike

I-OCPP 1.6 ihlala yamkelwa ngokubanzi ngenxa yokuvuthwa kwayo kunye nokuhambelana neenkqubo zelifa, kubandakanywa i-GB / T-based networks e-China. Nangona kunjalo, ukungahambelani kwe-OCPP 2.0 kunye neenguqulelo zangaphambili kubangela imingeni yokuphucula, nangona iimpawu zayo eziphezulu ezifana nenkxaso ye-V2G kunye nokulinganisa okuphezulu komthwalo.

Ukuqukumbela

Utshintsho olusuka kwi-OCPP 1.6 ukuya kwi-OCPP 2.0 lubonisa ukutsiba okubalulekileyo kwi-teknoloji ye-Electric Car Charging, eqhutywa ziimfuno zokhuseleko, ukusebenzisana, kunye nolawulo lwamandla ahlakaniphile. Ngelixa i-OCPP 1.6 yanele kwimisebenzi esisiseko ye-EV Charger, i-OCPP 2.0 iyimfuneko kubungqina bexesha elizayo beZitishi zokutshaja ze-EV, ngakumbi ezo zixhasayo.Ukutshaja ngokukhawuleza kwe-DC, CCS, kunye neV2G. Njengoko ishishini likhula, ukwamkela i-OCPP 2.0 kuya kubaluleka ekulungelelaniseni imigangatho yehlabathi kunye nokuphucula amava omsebenzisi kwii-Wallbox Charger kunye nee-hubs zokutshaja zoluntu.
