Kev Hloov Pauv ntawm Cov Txheej Txheem Them Nqi EV: Kev Tshawb Fawb Sib Piv ntawm OCPP 1.6 thiab OCPP 2.0

Kev loj hlob sai ntawmKev tsim kho vaj tse rau lub tsheb fais fabtau tsim cov txheej txheem sib txuas lus txheem kom ntseeg tau tias muaj kev sib koom tes ntawm EV Charging Stations thiab cov txheej txheem tswj hwm hauv nruab nrab. Ntawm cov txheej txheem no, OCPP (Open Charge Point Protocol) tau tshwm sim ua tus qauv thoob ntiaj teb. Tsab xov xwm no tshawb nrhiav qhov sib txawv tseem ceeb ntawm OCPP 1.6 thiab OCPP 2.0, tsom mus rau lawv qhov cuam tshuam rau EV Charger thev naus laus zis, kev them nqi zoo, thiab kev koom ua ke nrog cov qauv niaj hnub xws li CCS (Combined Charging System), GB / T, thiab DC them ceev.

1. Cov Qauv Txheej Txheem thiab Kev Sib Txuas Lus

OCPP 1.6, tau qhia tawm xyoo 2017, txhawb nqa ob qho tib si SOAP (dhau HTTP) thiab JSON (dhau WebSocket) hom ntawv, ua kom muaj kev sib txuas lus yooj ywm ntawmCov Khoom Siv Hluav Taws Xob Phab Ntsathiab cov kab ke hauv nruab nrab. Nws cov qauv xa xov asynchronous tso cai rauChaw Them Nqi EVlos tswj cov haujlwm xws li kev lees paub, kev tswj hwm kev lag luam, thiab kev hloov kho firmware.

OCPP 2.0.1(2020), qhov kev hloov tshiab kawg, siv cov qauv tsim kho kom ruaj khov dua nrog kev ruaj ntseg zoo dua. Nws yuam kom HTTPS rau kev sib txuas lus encrypted thiab qhia cov ntawv pov thawj digital rau kev lees paub cov khoom siv, daws qhov tsis muaj zog hauv cov qauv ua ntej. Qhov kev hloov kho tshiab no yog qhov tseem ceeb rauDC chaw them ceev ceev, qhov twg kev ncaj ncees ntawm cov ntaub ntawv thiab kev saib xyuas lub sijhawm tiag tiag yog qhov tseem ceeb tshaj plaws.

2. Kev Them Nqi Ntse thiab Kev Tswj Xyuas Zog

Ib qho tshwj xeeb ntawm OCPP 2.0 yog nws qhov kev ua tau zoo heevKev Them Nyiaj Ntsemuaj peev xwm. Tsis zoo li OCPP 1.6, uas muaj kev sib npaug ntawm qhov hnyav, OCPP 2.0 sib koom ua ke cov txheej txheem tswj hwm lub zog dynamic (EMS) thiab txhawb nqa Vehicle-to-Grid (V2G) technologies. Qhov no tso cai rauCov Chaw Them Hluav Taws Xob EVlos kho cov nqi them raws li qhov xav tau ntawm lub network lossis qhov muaj zog rov ua dua tshiab, ua kom zoo dua qhov kev faib hluav taws xob thoob plaws EV Charging Stations.

Piv txwv li, Wallbox Charger siv OCPP 2.0 tuaj yeem ua qhov tseem ceeb rau kev them thaum lub sijhawm tsis yog lub sijhawm siab tshaj plaws lossis txo lub zog thaum lub sijhawm muaj teeb meem ntawm lub network, ua kom muaj kev ua haujlwm zoo rau ob qho tib si hauv tsev thiab kev lag luam.Kev teeb tsa them fais fab tsheb.

3. Kev Ruaj Ntseg thiab Kev Ua Raws Cai

Txawm hais tias OCPP 1.6 vam khom cov txheej txheem lees paub yooj yim, OCPP 2.0 qhia txog kev kaw qhov kawg-rau-kawg thiab cov kos npe digital rau kev hloov kho firmware, txo cov kev pheej hmoo xws li kev nkag tsis raug cai lossis kev cuam tshuam. Qhov no tseem ceeb heev rauCCS thiab GB/T-raws li chaw nres tsheb, uas tswj cov ntaub ntawv rhiab heev ntawm tus neeg siv thiab cov kev lag luam DC muaj zog heev.

4. Cov Qauv Ntaub Ntawv Txhim Kho thiab Kev Ua Haujlwm

OCPP 2.0nthuav cov qauv ntaub ntawv los txhawb cov xwm txheej them nqi nyuaj. Nws qhia cov hom lus tshiab rau kev kuaj mob, kev tswj hwm kev tseg cia, thiab kev tshaj tawm xwm txheej tiag tiag, ua rau muaj kev tswj hwm zooChaw Them Nqi EVPiv txwv li, cov neeg teb xov tooj tuaj yeem tshawb xyuas qhov yuam kev hauvDC cov chaw them ceev ceevlossis hloov kho cov kev teeb tsa rau Wallbox Chargers yam tsis muaj kev cuam tshuam hauv tsev.

Qhov sib txawv, OCPP 1.6 tsis muaj kev txhawb nqa rau ISO 15118 (Plug & Charge), qhov kev txwv tau hais hauv OCPP 2.0 los ntawm kev sib koom ua ke nrog tus qauv no. Qhov kev nce qib no ua rau kev txheeb xyuas tus neeg siv yooj yim ntawm CCS thiab GB / T chaw nres tsheb, ua rau muaj kev paub "plug-and-charge".

5. Kev Sib Haum Xeeb thiab Kev Siv Lag Luam

OCPP 1.6 tseem siv tau dav vim nws loj hlob thiab sib haum nrog cov kab ke qub, suav nrog GB/T-based networks hauv Suav teb. Txawm li cas los xij, OCPP 2.0 qhov tsis sib haum nrog cov qauv ua ntej ua rau muaj kev cov nyom rau kev hloov kho dua tshiab, txawm tias nws cov yam ntxwv zoo dua xws li kev txhawb nqa rau V2G thiab kev sib npaug ntawm cov khoom siv.

Xaus lus

Kev hloov pauv ntawm OCPP 1.6 mus rau OCPP 2.0 yog ib qho kev dhia loj hauv kev siv tshuab them fais fab tsheb, uas yog vim muaj kev xav tau kev ruaj ntseg, kev sib koom tes, thiab kev tswj hwm lub zog ntse. Thaum OCPP 1.6 txaus rau kev ua haujlwm yooj yim ntawm EV Charger, OCPP 2.0 yog qhov tseem ceeb rau cov chaw them fais fab yav tom ntej, tshwj xeeb tshaj yog cov uas txhawb nqaDC them ceev ceev, CCS, thiab V2G. Raws li kev lag luam hloov zuj zus, kev txais yuav OCPP 2.0 yuav tseem ceeb heev rau kev sib haum xeeb nrog cov qauv thoob ntiaj teb thiab txhim kho cov kev paub ntawm cov neeg siv ntawm Wallbox Chargers thiab cov chaw them hluav taws xob rau pej xeem.
