Qhov Evolution of EV Charging Protocols: A Comparative Analysis of OCPP 1.6 and OCPP 2.0

Kev loj hlob sai ntawmElectric Tsheb Charging infrastructuretau tsim cov txheej txheem kev sib txuas lus tsim nyog los xyuas kom muaj kev sib cuam tshuam ntawm EV Charging Stations thiab lub hauv paus tswj hwm. Ntawm cov kev cai no, OCPP (Open Charge Point Protocol) tau tshwm sim los ua tus qauv ntsuas thoob ntiaj teb. Tsab ntawv xov xwm no tshawb txog qhov sib txawv tseem ceeb ntawm OCPP 1.6 thiab OCPP 2.0, tsom rau lawv qhov cuam tshuam rau EV Charger thev naus laus zis, kev them nqi hluav taws xob, thiab kev koom ua ke nrog cov qauv niaj hnub xws li CCS (Combined Charging System), GB / T, thiab DC them ceev ceev.

1. Cov qauv tsim qauv tsim qauv thiab kev sib txuas lus

OCPP 1.6, tau tshaj tawm xyoo 2017, txhawb nqa ob qho tib si SOAP (dhau HTTP) thiab JSON (dhau WebSocket) cov qauv, ua kom muaj kev sib txuas lus yooj yim ntawmWallbox Chargersthiab central systems. Nws asynchronous messaging qauv tso caiEV Charging Stationslos tswj cov haujlwm xws li kev lees paub, kev tswj hwm kev lag luam, thiab hloov kho firmware.

OCPP 2.0.1(2020), qhov tseeb iteration, txais yuav ib tug ruaj khov architecture nrog txhim khu kev ruaj ntseg. Nws txib HTTPS rau kev sib txuas lus encrypted thiab qhia cov ntawv pov thawj digital rau kev lees paub cov cuab yeej, hais txog qhov tsis zoo hauv cov qauv ua ntej. Qhov kev txhim kho no yog qhov tseem ceeb rauDC ceev them chaw nres tsheb, qhov twg cov ntaub ntawv ncaj ncees thiab kev saib xyuas lub sijhawm tiag tiag yog qhov tseem ceeb.

2. Kev them nqi ntse thiab kev tswj xyuas hluav taws xob

Qhov zoo tshaj plaws ntawm OCPP 2.0 yog nws cov qib siabKev them nyiaj ntsepeev xwm. Tsis zoo li OCPP 1.6, uas muaj qhov sib npaug ntawm qhov yooj yim, OCPP 2.0 integrates dynamic zog tswj systems (EMS) thiab txhawb nqa tsheb-rau-Grid (V2G) technologies. Qhov no tso caiEV Chargerslos kho tus nqi them raws li daim phiaj xav tau lossis muaj lub zog txuas ntxiv dua tshiab, ua kom lub zog faib tawm thoob plaws EV Charging Stations.

Piv txwv li, Wallbox Charger siv OCPP 2.0 tuaj yeem ua qhov tseem ceeb ntawm kev them nyiaj thaum lub sijhawm tsis nco qab lossis txo lub zog thaum muaj kev sib tsoo, txhim kho kev ua haujlwm rau ob qho tib si hauv tsev thiab kev lag luam.Electric Tsheb Charging setups.

3. Kev ruaj ntseg thiab ua raws

Thaum OCPP 1.6 tso siab rau cov txheej txheem kev lees paub qhov tseeb, OCPP 2.0 qhia txog qhov kawg-rau-kawg encryption thiab kos npe digital rau kev hloov kho firmware, txo cov kev pheej hmoo xws li kev nkag tsis tau lossis cuam tshuam. Qhov no yog qhov tseem ceeb tshwj xeeb rauCCS thiab GB / T-raws li chaw nres tsheb, uas tswj cov neeg siv cov ntaub ntawv rhiab heev thiab lub zog DC kev lag luam.

4. Txhim kho cov qauv ntaub ntawv thiab kev ua haujlwm

OCPP 2.0nthuav cov ntaub ntawv qauv los txhawb cov txheej txheem them nyiaj nyuaj. Nws nthuav tawm cov lus tshiab rau kev kuaj mob, kev tswj xyuas kev tuav pov hwm, thiab tshaj tawm cov xwm txheej ntawm lub sijhawm, ua kom muaj kev tswj xyuas granular.EV Charging Stations. Piv txwv li, cov neeg ua haujlwm tuaj yeem kuaj xyuas qhov tsis raug hauvDC fast charging unitslos yog hloov kho kev teeb tsa rau Wallbox Chargers yam tsis muaj kev cuam tshuam ntawm qhov chaw.

Hauv qhov sib piv, OCPP 1.6 tsis muaj kev txhawb nqa ib txwm muaj rau ISO 15118 (Plug & Charge), ib qho kev txwv nyob rau hauv OCPP 2.0 los ntawm kev sib txuam nrog cov qauv no. Qhov kev nce qib no ua kom yooj yim rau cov neeg siv kev lees paub ntawm CCS thiab GB / T chaw nres tsheb, ua rau "plug-thiab-them" kev paub.

5. Kev sib raug zoo thiab kev ua lag luam txais yuav

OCPP 1.6 tseem siv dav vim nws qhov kev loj hlob thiab kev sib raug zoo nrog cov txheej txheem qub qub, suav nrog GB / T-raws li kev sib txuas hauv Suav teb. Txawm li cas los xij, OCPP 2.0 qhov tsis sib xws nrog cov qauv ua ntej ua rau muaj kev sib tw rau kev hloov kho dua tshiab, txawm tias nws cov yam ntxwv zoo tshaj plaws xws li kev txhawb nqa rau V2G thiab kev ntsuas siab siab.

Xaus

Kev hloov pauv ntawm OCPP 1.6 mus rau OCPP 2.0 yog qhov tseem ceeb ntawm kev dhia hauv Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob, uas tau tsav los ntawm kev xav tau kev ruaj ntseg, kev sib cuam tshuam, thiab kev tswj xyuas lub zog ntse. Thaum OCPP 1.6 txaus rau cov haujlwm yooj yim EV Charger, OCPP 2.0 yog qhov tseem ceeb rau yav tom ntej-pov thawj EV Charging Stations, tshwj xeeb tshaj yog cov txhawb nqa.DC them ceev ceev, CCS, thiab V2G. Raws li kev lag luam hloov zuj zus, kev siv OCPP 2.0 yuav yog qhov tseem ceeb rau kev ua raws li cov qauv thoob ntiaj teb thiab txhim kho cov neeg siv kev paub ntawm Wallbox Chargers thiab cov chaw them nyiaj rau pej xeem.
