Them pawg-OCPP them kev sib txuas lus raws tu qauv qhia

1. Taw qhia txog OCPP raws tu qauv

Lub npe tag nrho ntawm OCPP yog Open Charge Point Protocol, uas yog cov txheej txheem pub dawb thiab qhib tsim los ntawm OCA (Open Charging Alliance), ib lub koom haum nyob hauv Netherlands. Qhib Charge Point Protocol (OCPP) Qhib Charge Point Protocol yog siv rau kev sib txuas lus kev daws teeb meem ntawm cov chaw them nqi (CS) thiab txhua qhov chaw them nqi tswj hwm qhov system (CSMS). Cov txheej txheem kev tsim qauv no txhawb kev sib txuas ntawm txhua qhov kev pabcuam them nyiaj lub hauv paus kev tswj hwm nrog txhua pawg them, thiab feem ntau yog siv los daws ntau yam teeb meem tshwm sim los ntawm kev sib txuas lus ntawm kev them nyiaj ntiag tug. OCPP txhawb nqa kev sib txuas lus tsis sib haum xeeb ntawm cov chaw them nqi thiab kev tswj hwm hauv nruab nrab ntawm txhua tus neeg xa khoom. Qhov xwm txheej kaw ntawm kev them nyiaj ntiag tug tau ua rau muaj kev ntxhov siab tsis tsim nyog rau ntau tus tswv tsheb hluav taws xob thiab cov neeg saib xyuas vaj tse nyob rau ntau xyoo dhau los, ua rau muaj kev hu xov tooj thoob plaws hauv kev lag luam rau cov qauv qhib. Qhov zoo ntawm OCPP raws tu qauv: qhib rau kev siv dawb, tiv thaiv kev xauv nkag ntawm ib tus neeg xa khoom (them lub platform), txo cov sijhawm sib koom ua ke / ua haujlwm thiab IT teeb meem.

2. Taw qhia rau OCPP version txhim kho

Xyoo 2009, lub tuam txhab Dutch ElaadNL tau pib tsim lub Open Charging Alliance, uas yog lub luag haujlwm tseem ceeb rau kev txhawb nqa qhib kev them nyiaj raws tu qauv OCPP thiab qhib kev them nyiaj ntse OSCP. Tam sim no muaj los ntawm OCA; OCPP tuaj yeem txhawb nqa txhua hom kev them nyiaj thev naus laus zis.

3. OCPP version qhia

Raws li qhia hauv qab no, los ntawm OCPP1.5 mus rau qhov tseeb OCPP2.0.1

(1) OCPP1.2 (SOAP)

(2) OCPP1.5 (SOAP)

Txij li thaum muaj ntau txoj cai ntiag tug hauv kev lag luam uas tsis tuaj yeem txhawb nqa kev pabcuam kev sib koom ua ke thiab kev sib koom ua haujlwm ntawm cov neeg ua haujlwm sib txawv cov kev pabcuam, OCA tau ua tus thawj coj hauv kev tsim cov txheej txheem qhib OCPP1.5. SOAP raug txwv los ntawm kev txwv ntawm nws tus kheej raws tu qauv thiab tsis tuaj yeem txhawb nqa sai ntawm qhov loj.

OCPP 1.5 sib txuas lus nrog lub hauv paus system ntawm SOAP raws tu qauv dhau HTTP los ua haujlwm them cov ntsiab lus. Nws txhawb nqa cov yam ntxwv hauv qab no: Kev lag luam hauv zos thiab hauv thaj chaw deb, suav nrog kev ntsuas kev them nqi

(3) OCPP1.6(SOAP/JSON)

OCPP version 1.6 ntxiv qhov kev siv ntawm JSON hom thiab ua rau kom muaj peev xwm ntawm kev them nyiaj ntse. JSON version sib txuas lus los ntawm WebSocket, uas tuaj yeem xa cov ntaub ntawv rau ib leeg hauv ib puag ncig network. Feem ntau siv raws tu qauv ntawm kev ua lag luam tam sim no yog version 1.6J.

Txhawb JSON hom ntaub ntawv raws li websockets raws tu qauv kom txo tau cov ntaub ntawv khiav tsheb (JSON, JavaScript Object Notation, yog ib tug sib sib zog nqus cov ntaub ntawv pauv hom) thiab tso cai rau ua hauj lwm nyob rau hauv tes hauj lwm uas tsis txhawb them point packet routing (xws li pej xeem internet). Kev them nyiaj ntse: thauj khoom sib npaug, nruab nrab ntse them nyiaj thiab hauv zos ntse charging. Cia qhov chaw them nqi rov xa nws cov ntaub ntawv (raws li cov ntaub ntawv them nqi tam sim no), xws li tus nqi ntsuas qhov kawg lossis qhov xwm txheej ntawm qhov chaw them nqi.

(4) OCPP 2.0 (JSON)

OCPP2.0, tso tawm rau xyoo 2018, txhim kho kev lag luam kev lag luam, nce kev ruaj ntseg, thiab kev tswj cov cuab yeej: ntxiv cov kev them nyiaj ntse, rau kev tswj hwm lub zog (EMS), cov tswj hwm hauv zos, thiab rau kev sib xyaw ntse ntawm cov tsheb hluav taws xob, Topology ntawm cov chaw them nqi thiab them chaw nres tsheb tswj systems. Txhawb ISO 15118: Plug-and-play thiab ntse them cov cai rau cov tsheb fais fab.

(5) OCPP2.0.1 (JSON)

OCPP 2.0.1 yog qhov tseeb version, tso tawm xyoo 2020. Nws muaj cov yam ntxwv tshiab thiab kev txhim kho xws li kev txhawb nqa ISO15118 (plug thiab ua si), txhim kho kev ruaj ntseg, thiab kev txhim kho tag nrho.
