1. Kev Taw Qhia Txog OCPP protocol
Lub npe tag nrho ntawm OCPP yog Open Charge Point Protocol, uas yog ib qho protocol pub dawb thiab qhib uas tsim los ntawm OCA (Open Charging Alliance), ib lub koom haum nyob hauv Netherlands. Open Charge Point Protocol (OCPP) Open Charge Point Protocol yog siv rau kev sib txuas lus sib koom ua ke ntawm cov chaw them nqi (CS) thiab txhua lub chaw tswj hwm chaw them nqi (CSMS). Cov qauv protocol no txhawb nqa kev sib txuas lus ntawm txhua tus neeg muab kev pabcuam them nqi lub hauv paus tswj hwm nrog txhua lub pawg them nqi, thiab feem ntau yog siv los daws ntau yam teeb meem los ntawm kev sib txuas lus ntawm cov tes hauj lwm them nqi ntiag tug. OCPP txhawb nqa kev tswj hwm kev sib txuas lus tsis muaj kev sib txuas lus ntawm cov chaw them nqi thiab cov txheej txheem tswj hwm ntawm txhua tus neeg muab khoom. Qhov xwm txheej kaw ntawm cov tes hauj lwm them nqi ntiag tug tau ua rau muaj kev ntxhov siab tsis tsim nyog rau ntau tus tswv tsheb fais fab thiab cov thawj coj khoom vaj khoom tsev ntau xyoo dhau los, ua rau muaj kev hu xov tooj thoob plaws hauv kev lag luam rau tus qauv qhib. Cov txiaj ntsig ntawm OCPP protocol: qhib rau kev siv dawb, tiv thaiv kev xauv ntawm ib tus neeg muab khoom (lub platform them nqi), txo lub sijhawm sib koom ua ke / kev ua haujlwm thiab teeb meem IT.
2. Kev Taw Qhia Txog Kev Tsim Kho OCPP Version
Xyoo 2009, lub tuam txhab Dutch ElaadNL tau pib tsim tsa Open Charging Alliance, uas yog lub luag haujlwm tseem ceeb rau kev txhawb nqa txoj cai them nqi qhib OCPP thiab txoj cai them nqi ntse qhib OSCP. Tam sim no OCA muaj; OCPP tuaj yeem txhawb nqa txhua hom thev naus laus zis them nqi.
3. Kev taw qhia txog OCPP version
Raws li qhia hauv qab no, txij li OCPP1.5 mus rau qhov tseeb tshaj plaws OCPP2.0.1
(1) OCPP1.2(Xab npum)
(2)OCPP1.5 (Xab npum)
Vim tias muaj ntau cov txheej txheem ntiag tug hauv kev lag luam uas tsis tuaj yeem txhawb nqa kev pabcuam sib koom ua ke thiab kev sib txuas lus ua haujlwm ntawm cov kev pabcuam sib txawv, OCA tau ua tus thawj coj hauv kev tsim cov txheej txheem qhib OCPP1.5. SOAP raug txwv los ntawm cov kev txwv ntawm nws tus kheej cov txheej txheem thiab tsis tuaj yeem txhawb nqa sai sai ntawm qhov loj.
OCPP 1.5 sib txuas lus nrog lub hauv paus ntawm SOAP protocol hla HTTP los ua haujlwm cov chaw them nqi. Nws txhawb nqa cov yam ntxwv hauv qab no: Kev lag luam hauv zos thiab chaw deb, suav nrog kev ntsuas rau kev them nqi.
(3) OCPP1.6(SOAP/JSON)
OCPP version 1.6 ntxiv kev siv hom ntawv JSON thiab ua rau kom muaj peev xwm ntxiv ntawm kev them nqi ntse. JSON version sib txuas lus los ntawm WebSocket, uas tuaj yeem xa cov ntaub ntawv mus rau ib leeg hauv txhua qhov chaw hauv network. Cov txheej txheem feem ntau siv hauv kev ua lag luam tam sim no yog version 1.6J.
Txhawb cov ntaub ntawv hom JSON raws li cov txheej txheem websockets los txo cov ntaub ntawv khiav (JSON, JavaScript Object Notation, yog hom ntawv sib pauv ntaub ntawv sib txawv) thiab tso cai rau kev ua haujlwm ntawm cov tes hauj lwm uas tsis txhawb nqa cov chaw them nqi pob ntawv (xws li internet pej xeem). Kev them nqi ntse: kev sib npaug ntawm qhov hnyav, kev them nqi ntse hauv nruab nrab thiab kev them nqi ntse hauv zos. Cia qhov chaw them nqi xa nws cov ntaub ntawv dua (raws li cov ntaub ntawv tam sim no), xws li tus nqi ntsuas kawg lossis qhov xwm txheej ntawm qhov chaw them nqi.
(4) OCPP2.0 (JSON)
OCPP2.0, tso tawm xyoo 2018, txhim kho kev ua tiav kev lag luam, nce kev ruaj ntseg, thiab kev tswj hwm cov khoom siv: ntxiv cov haujlwm them nyiaj ntse, rau topology nrog cov txheej txheem tswj hwm lub zog (EMS), cov tswj hwm hauv zos, thiab rau kev them nyiaj ntse ntawm cov tsheb fais fab, Topology ntawm cov chaw them nyiaj thiab cov txheej txheem tswj hwm chaw them nyiaj. Txhawb nqa ISO 15118: Plug-and-play thiab cov kev cai them nyiaj ntse rau cov tsheb fais fab.
(5) OCPP2.0.1 (JSON)
OCPP 2.0.1 yog qhov version tshiab tshaj plaws, tso tawm xyoo 2020. Nws muaj cov yam ntxwv tshiab thiab kev txhim kho xws li kev txhawb nqa rau ISO15118 (plug thiab ua si), kev ruaj ntseg zoo dua, thiab kev txhim kho kev ua haujlwm tag nrho.
