I-charging pile–OCPP charging communication protocol intshayelelo

1. Intshayelelo kwiprotocol ye-OCPP

Igama elipheleleyo le-OCPP yi-Open Charge Point Protocol, eyi-protocol yasimahla nevulekileyo eyenziwe yi-OCA (Open Charging Alliance), umbutho okwiNetherlands. I-Open Charge Point Protocol (OCPP) i-Open Charge Point Protocol isetyenziselwa izisombululo zonxibelelwano ezidibeneyo phakathi kwezikhululo zokutshaja (CS) kunye nayo nayiphi na inkqubo yolawulo lwezikhululo zokutshaja (CSMS). Olu lwakhiwo lwe-protocol luxhasa ukunxibelelana kwenkqubo yolawulo oluphakathi yomboneleli weenkonzo zokutshaja nazo zonke iinqwaba zokutshaja, kwaye isetyenziselwa ikakhulu ukusombulula iingxaki ezahlukeneyo ezibangelwa lunxibelelwano phakathi kwenethiwekhi zokutshaja zabucala. I-OCPP ixhasa ulawulo lonxibelelwano olungenamthungo phakathi kwezikhululo zokutshaja kunye neenkqubo zolawulo oluphakathi zomthengisi ngamnye. Uhlobo oluvaliweyo lweenethiwekhi zokutshaja zabucala lubangele ukukhungatheka okungeyomfuneko kwinani elikhulu labanini bezithuthi zombane kunye nabaphathi bepropathi kwiminyaka emininzi edlulileyo, nto leyo ebangele ukuba kubhengezwe iifowuni ezininzi kulo lonke ishishini zemodeli evulekileyo. Iingenelo ze-protocol ye-OCPP: ivulelekile ukusetyenziswa simahla, ithintela ukuvalelwa komthengisi omnye (iqonga lokutshaja), ukunciphisa ixesha/umthwalo womsebenzi wokudibanisa kunye nemiba ye-IT.

2. Intshayelelo kuphuhliso lwenguqulelo ye-OCPP

Ngowama-2009, inkampani yaseDatshi i-ElaadNL yaqalisa ukusekwa kwe-Open Charging Alliance, enoxanduva olukhulu lokukhuthaza i-open charging protocol OCPP kunye ne-open smart charging protocol OSCP. Ngoku iphantsi kwe-OCA; i-OCPP inokuxhasa zonke iintlobo zobuchwepheshe bokutshaja.

3. Intshayelelo yenguqulelo ye-OCPP

Njengoko kubonisiwe ngezantsi, ukusuka kwi-OCPP1.5 ukuya kwi-OCPP2.0.1 yamva nje

(1) OCPP1.2 (ISEPHA)

(2)OCPP1.5 (ISEPHA)

Ekubeni kukho iiprotokholi ezininzi zabucala kushishino ezingenakuxhasa amava enkonzo edibeneyo kunye nonxibelelwano lokusebenza phakathi kweenkonzo ezahlukeneyo zabaqhubi, i-OCA ithathe inyathelo lokuqala ekwenzeni iprotokholi evulekileyo i-OCPP1.5. I-SOAP ithintelwe yimida yeprotokholi yayo kwaye ayinakukhuthazwa ngokukhawuleza kwinqanaba elikhulu.

I-OCPP 1.5 inxibelelana nenkqubo ephakathi ngeprotocol ye-SOAP nge-HTTP ukuze isebenze iindawo zokutshaja. Ixhasa ezi mpawu zilandelayo: Iintengiselwano zasekhaya neziqalwe kude, kubandakanya ukulinganisa iindleko

(3) OCPP1.6 (SOAP/JSON)

Inguqulelo ye-OCPP 1.6 yongeza ukusetyenziswa kwefomathi ye-JSON kwaye yonyusa ukwandiswa kokutshaja okukrelekrele. Inguqulelo ye-JSON inxibelelana ngeWebSocket, enokuthumelana idatha kuyo nayiphi na indawo yenethiwekhi. Eyona protocol isetyenziswa kakhulu kwimarike okwangoku yinguqulelo 1.6J.

Ixhasa idatha yefomathi yeJSON esekwe kwi-websockets protocol ukunciphisa ithrafikhi yedatha (i-JSON, iJavaScript Object Notation, yifomathi yotshintshiselwano lwedatha olulula) kwaye ivumela ukusebenza kwiinethiwekhi ezingaxhasi ukuhanjiswa kwepakethi yenqaku lokutshaja (njenge-intanethi kawonkewonke). Ukutshaja okukrelekrele: ukulinganisela umthwalo, ukutshaja okukrelekrele okuphakathi kunye nokutshaja okukrelekrele kwendawo. Vumela indawo yokutshaja ithumele kwakhona ulwazi lwayo (ngokusekelwe kulwazi lwangoku lwenqaku lokutshaja), njengexabiso lokugqibela lokulinganisa okanye imeko yendawo yokutshaja.

(4) I-OCPP2.0 (i-JSON)

I-OCPP2.0, eyakhutshwa ngo-2018, iphucula ukuqhubekeka kwentengiselwano, yonyusa ukhuseleko, kunye nolawulo lwesixhobo: yongeza imisebenzi yokutshaja ekrelekrele, kwiitopoloji ezineenkqubo zolawulo lwamandla (EMS), abalawuli bendawo, kunye nokutshaja okukrelekrele okudibeneyo kwezithuthi zombane, Iitopology zezikhululo zokutshaja kunye neenkqubo zolawulo lwezikhululo zokutshaja. Ixhasa i-ISO 15118: Iimfuno zokutshaja kunye nokudlala kunye nokutshaja okukrelekrele kwezithuthi zombane.

(5) OCPP2.0.1 (JSON)

I-OCPP 2.0.1 yinguqulelo yamva nje, ekhutshwe ngo-2020. Ibonelela ngeempawu ezintsha kunye nophuculo olufana nenkxaso ye-ISO15118 (iplagi kunye nokudlala), ukhuseleko oluphuculweyo, kunye nophuculo lokusebenza ngokubanzi.
