ISO 15118-20: 2022 / AMD 1: 2026 kev txhais lus los ntawm ib yam khoom: Muaj dab tsi hloov pauv hauv txhua qhov kev hloov kho?

Lub npe tag nrho:ISO 15118-20: 2022 / Amd 1: 2026 Cov tsheb hauv kev - Kev sib txuas lus ntawm lub tsheb mus rau lub grid - Ntu 20: Cov kev cai ntawm txheej txheej network thiab txheej txheej thov thib 2 - Kev Hloov Kho 1: Kev pabcuam AC DER, kev pabcuam MCS, thiab lub tswv yim kev ruaj ntseg zoo dua

Vim li cas tus qauv thoob ntiaj teb uas nyuam qhuav luam tawm tau ob peb xyoos xwb thiaj yuav tsum tau kho dua tshiab? Qhov no puas txhais tau tias ISO 15118-20 tseem tsis tau tiav?

Ntu I: Cov Lus Qhia Txog Kev Cai Lij Choj - Kev Nthuav Dav ntawm Lub Txheej Txheem Txheem

Kev Hloov Kho 1 tau ntxiv ob qho qauv tshiab rau kev siv:

• ISO 15118-10:2025
• IEC 61851-23-3:2025

Qhov no yog qhov kev hloov pauv yooj yim tshaj plaws uas tsis tau saib xyuas tab sis tseem ceeb tshaj plaws hauv tag nrho qhov kev hloov kho.

ISO 15118-20 thawj zaug tau tsim los ntawm kev sib txuas lus PLC, thaum ISO 15118-10 txhais cov kev cai ntawm lub cev thiab cov txheej txheem txuas ntaub ntawv rau Single Pair Ethernet (10BASE-T1S); IEC 61851-23-3 yog thawj zaug uas tau teev tseg cov khoom siv them MCS DC.

Hauv lwm lo lus, txij lub sijhawm no mus, ISO 15118-20 yuav tsis tsuas yog pab CCS xwb, tab sis kuj tseem yuav pab cov tshuab them hluav taws xob megawatt.

Ntu 2: Muaj ntau tshaj kaum lo lus tshiab tau ntxiv - ISO 15118 tam sim no nkag mus rau hauv thaj chaw fais fab, suav nrog:

Cov lus no muaj ib qho cwj pwm zoo sib xws: feem ntau ntawm lawv tsis yog los ntawm kev lag luam tsheb, tab sis los ntawm thaj chaw ntawm kev tswj hwm txuas nrog grid. Qhov no qhia tau hais tias ISO 15118 tau pib suav nrog cov tswv yim tswj hwm los ntawm cov qauv zog faib tawm xws li IEEE 1547. Yav dhau los, cov tsheb tsuas yog cov khoom siv them xwb. Yav tom ntej, cov tsheb yuav raug suav hais tias yog cov peev txheej zog uas muaj peev xwm koom nrog kev tswj hwm zaus grid, kev tswj hwm voltage, thiab kev teb rau qhov xav tau. Qhov no sawv cev rau ib qho ntawm cov kev hloov pauv tseem ceeb tshaj plaws uas tau coj los ntawm Kev Hloov Kho 1.

Tshooj 3: MCS Tau Los Ua Ib Feem Ntawm ISO 15118

Qhov no yog cov ntsiab lus tseem ceeb tshaj plaws ntawm tag nrho cov kev hloov kho.

1. Qhia txog MCS txoj kev pw tsaug zog
2. Yuav tsum tau txais 10BASE-T1S:
3. Tsis sib xws nrog ISO 15118-2 lawm

Tshooj IV: PKI Security System Nkag Mus Rau Theem Engineering

Qhov kev hloov kho no tau rov sau dua tag nrho Online Certificate Status Protocol (OCSP) thiab cov txheej txheem txheeb xyuas daim ntawv pov thawj.

Cov kev hloov pauv tseem ceeb suav nrog:

Ua ntej tshaj,Cov Kev Cai Tshiab V2G20-3000 thiab 3001 tau ntxiv lawm, uas yuav tsum tau kom lub sijhawm siv tau ntawm txhua daim ntawv pov thawj yuav tsum muaj nyob rau hauv lub sijhawm siv tau ntawm daim ntawv pov thawj ntawm tus neeg muab daim ntawv pov thawj, thiab EVCC thiab SECC yuav tsum tau ua cov kev kuaj xyuas thaum lub sijhawm txheeb xyuas.

Qhov thib ob,cov lus qhia txog qhov loj ntawm cov ntawv pov thawj tshiab ntxiv.

Qhov thib peb,hloov kho dua tshiab tag nrho cov kev txheeb xyuas OCSP.

Xws li daim ntawv pov thawj SECC, Daim Ntawv Pov Thawj Tsheb, Daim Ntawv Pov Thawj Daim Ntawv Cog Lus, thiab Daim Ntawv Pov Thawj OEM Provisioning, ntau yam kev cai tau hloov pauv, uas yuav tsum tau daim ntawv pov thawj kos npe OCSP yuav tsum sib xws nrog Root CA sib xws, thiab txuas ntxiv ua kom muaj kev sib raug zoo ntawm kev ntseeg siab ntawm cov saw hlau sib txawv.

Txawm hais tias cov kev hloov kho no tsis cuam tshuam ncaj qha rau cov lus ntawm cov txheej txheem thov, lawv txiav txim siab seb Plug & Charge puas tuaj yeem ua tiav kev sib txuas thoob ntiaj teb yav tom ntej.

Tshooj 5: TLS handshake logic yog qhov nruj dua

• Cov xwm txheej xa rau daim ntawv pov thawj_authorities txuas ntxiv hauv ClientHello;
• ServerHello xaiv ib daim ntawv pov thawj li cas;
• Public SECC thiab Private SECC txais yuav cov tswv yim sib txawv;
• Txoj kev thov daim ntawv pov thawj hauv CertificateRequest tau piav qhia ntxiv;
• EVCC xaiv cov saw hlau daim ntawv pov thawj uas tsim nyog tshaj plaws li cas raws li Lub Npe Tshwj Xeeb.

Cov kev hloov kho no txhua yam tig mus rau ib lub hom phiaj: kom txo cov teeb meem sib koom tes thaum lub sijhawm hla-Root CA xa tawm thiab txhim kho kev sib raug zoo ntawm cov kab ke PKI sib txawv.

Ntu VI: Kev Pabcuam AC DER - ISO 15118 Ua Ntej Txhawb Kev Pabcuam Zog Faib Tawm ntawm Sab AC

Tsis zoo li qhov kev nce ntxiv ntawm cov kev xav tau kev sib txuas lus rau MCS, cov kev hloov kho ntsig txog AC DER feem ntau tsom mus rau kev txhim kho peev xwm yooj yim. Lub hom phiaj yog kom ISO 15118 txhawb nqa kev sib txuas lus ntawm AC Distributed Energy Resource (AC DER) cov kev pabcuam, es tsis yog tsim dua ib txoj cai sib txuas lus tshiab.

Tsis zoo li Kev Pabcuam Them Nqi AC ib txwm muaj, Kev Pabcuam AC DER tsis yog tsuas yog tsom mus rau cov txheej txheem them nqi xwb, tab sis yog rau kev sib pauv cov ntaub ntawv ntawm cov tsheb ua cov peev txheej fais fab faib tawm uas koom nrog kev ua haujlwm ntawm lub zog AC.

• Ntxiv cov kev cai cuam tshuam nrog rau qhov xwm txheej ua haujlwm ntawm DER;
• Ntxiv cov lus piav qhia ntawm DER tswj kev muaj peev xwm;

ISO 15118-20: 2022 / AMD 1: 2026 txhais li cas tiag?

Yog tias tag nrho cov kev hloov kho raug muab tso ua ke, nws yuav pom tias lawv txhua tus tig ib ncig ntawm peb qhov kev taw qhia.

Yog li ntawd, Kev Hloov Kho 1 tau muab kev paub txog kev lag luam ntawm ob peb xyoos dhau los tso rau hauv tus qauv thoob ntiaj teb. Qhov no ua rau ISO 15118-20 muaj peev xwm txhawb nqa MCS, V2G, thiab lub ntiaj teb PKI ecosystem thawj zaug. Nws kuj qhia tau tias, txij li xyoo 2026, kev lag luam tau nkag mus rau theem tsim kho ecosystem tiam ob ntawm ISO 15118. Qhov no yog lub sijhawm tseem ceeb rau cov qauv khoom tshiab.
