Kev piav qhia ntxaws txog lub hauv paus ntsiab lus ua haujlwm ntawm PnC Plug&Charge kev pabcuam them nqi -1

1、 Theem kev tsim kev ntseeg siab ntawm cov tsheb thiab cov chaw them nqi

Kev txheeb xyuas tus kheej:Lub chaw them hluav taws xob xyuas nws tus kheej los ntawm daim ntawv pov thawj SECC (Supply Equipment Communication Controller), thaum lub tsheb siv daim ntawv pov thawj V2G root (Trust Anchor) uas tau teeb tsa ua ntej los xyuas dua. Txhawm rau tiv thaiv kev tawm tsam cuav daim ntawv pov thawj, lub kaw lus tau qhia txog OCSP (Online Certificate Status Protocol). Hauv tus qauv ISO15118-20 tshiab kawg, kev txheeb xyuas kev tshem tawm lub sijhawm tiag tiag yog qhov yuav tsum tau ua rau txhua daim ntawv pov thawj (suav nrog Sub CA thiab Leaf daim ntawv pov thawj) kom ntseeg tau tias txhua qhov kev sib txuas lus raug saib xyuas nruj.

Nyob rau theem no, lub tsheb (EV) thiab chaw them hluav taws xob (EVSE) sib tuav tes raws li ISO 15118 protocol. Tom qab ua tiav qhov kev ua haujlwm ntxig rab phom thiab tsim kom muaj kev sib txuas lus digital, ob tog yuav sib tham los txiav txim siab txog daim ntawv thov version ntawm Transport Layer Security Protocol (TLS):

• TLS 1.2siv rau hauv tus qauv ISO 15118-2;
• Thaum siv lubISO 15118-20tus qauv,TLS 1.3yog saws txais;

1. Lub chaw them hluav taws xob muab nws daim ntawv pov thawj rau lub tsheb fais fab, suav nrog daim ntawv pov thawj Supply Equipment Communication Controller (SECC) thiab daim ntawv pov thawj Charge Operator (CPO) Intermediate Certificate Authority (Sub CA), los ua kom tiav qhov kev lees paub tus kheej ntawm lub tsheb.
2. Cov tsheb fais fab siv cov anchors ntseeg siab uas tau teeb tsa ua ntej (piv txwv li daim ntawv pov thawj V2G uas tau teeb tsa ua ntej xa tsheb mus rau cov neeg siv) los txheeb xyuas cov saw hlau daim ntawv pov thawj tag nrho uas cov chaw them hluav taws xob xa tuaj.
3. Cov tsheb fais fab yuav raug txheeb xyuas qhov xwm txheej ntawm daim ntawv pov thawj raug tshem tawm: Raws li tus qauv ISO 15118-2, daim ntawv pov thawj SECC tau tsim los nrog lub sijhawm luv luv (2-3 lub hlis), thiab qhov xwm txheej ntawm daim ntawv pov thawj CPO Sub CA raug txheeb xyuas los ntawm Online Certificate Status Protocol (OCSP); Tus qauv ISO 15118-20 xav kom txhua daim ntawv pov thawj raug txheeb xyuas qhov xwm txheej raug tshem tawm los ntawm OCSP.
4. Tom qab ua tiav txhua kauj ruam kev txheeb xyuas tiav lawm, lub tsheb fais fab tuaj yeem lees paub qhov tseeb ntawm qhov chaw them hluav taws xob, thiab cov ntaub ntawv sib txuas lus tag nrho tom qab ntawd yuav raug xa mus siv cov txheej txheem encrypted.

2. Kev sib tham txog txoj kev lees paub tus kheej

Qhov kev xav sib txawv ntawm EIM thiab PnC: Cov txheej txheem txwv tsis pub ua "kev lees paub tus kheej ob npaug" rau cov neeg siv. Yog tias pom tias tus neeg siv tau pib ua haujlwm los ntawm RFID lossis App (Hom EIM), qhov chaw them nqi yuav tsum txiav tawm cov txheej txheem PnC kom tsis txhob muaj kev pheej hmoo ua lag luam ntawm kev them nqi ob zaug.

Tus qauv ISO 15118 txhais ob lub tshuab lees paub tus kheej ntawm kev them nqi:

• 1. Cov Txhais Kev Txheeb Xyuas Sab Nraud (EIM):npog cov npav Radio Frequency Identification (RFID), daim npav rho nyiaj, cov ntawv thov mobile, QR code, thiab lwm yam;
• 2. Ntsaws & Them:Ib txoj kev lees paub tag nrho uas siv cov ntawv pov thawj.

Kev txwv tseem ceeb:Cov chaw them nqi yuav tsum tsis txhob ua ob lub cim rau cov neeg siv. Yog tias tus neeg siv ua tiav kev lees paub los ntawm cov cuab yeej sab nraud xws li daim npav RFID ua ntej txuas lub phom them nqi, qhov chaw them nqi yuav tsum txiav tawm qhov ua haujlwm ntsaws thiab ua si; ​​Txwv tsis pub, nws yuav ua rau lub tsheb tau txais daim ntawv pov thawj ntau zaus los ntawm daim ntawv pov thawj cog lus, ua rau muaj kev pheej hmoo ntawm kev them nqi ntau zaus.

3, theem txheeb xyuas tus kheej ntawm lub tsheb

Tom qab lub kaw lus xaiv hom them hluav taws xob ntsaws thiab ua si, lub tsheb fais fab xa daim ntawv pov thawj cog lus thiab daim ntawv pov thawj Mobile Service Provider (MSP) Sub CA rau qhov chaw them hluav taws xob. Cov ntawv pov thawj saum toj no tau koom ua ke rau hauv daim ntawv pov thawj tiav, thiab cov txheej txheem txheeb xyuas tus kheej tseem ceeb tau pib ua haujlwm. Lub backend yuav ua ntau qhov kev kuaj xyuas kev ruaj ntseg sib xws kom ntseeg tau tias kev them nqi raug cai, qhov tseeb ntawm cov nyiaj them nqi, thiab tiv thaiv kev pheej hmoo ntawm kev cuav tus kheej ntawm lub tsheb.

Txhawm rau tiv thaiv kev tawm tsam rov ua dua (piv txwv li cov neeg nyiag khoom cuam tshuam cov lus tso cai thiab xa lawv rov qab ntau zaus), lub kaw lus tsim cov lej sib tw random 128 ntsis. Lub tsheb yuav tsum siv tus yuam sij ntiag tug los kos npe rau tus lej sib tw, thiab qhov chaw them nqi yuav ua qhov kev txheeb xyuas kos npe theem millisecond hauv zos siv tus yuam sij pej xeem ntawm daim ntawv pov thawj daim ntawv cog lus. Qhov kev sib txuas lus tsis sib xws no ua kom ntseeg tau tias qhov tshwj xeeb thiab tsis lees paub qhov kev tso cai tam sim ntawd.

1. Kev txheeb xyuas qhov tseeb ntawm cov pawg them nqi ntawm cov saw hlau daim ntawv pov thawj

Lub chaw them hluav taws xob lossis CPO backend system yuav tsum ua tiav ob qhov kev txheeb xyuas tseem ceeb hauv qab no:

• Kev txheeb xyuas qhov tseeb:Paub tseeb tias txhua daim ntawv pov thawj hauv cov saw hlau ntawv pov thawj nyob hauv lawv lub sijhawm siv tau;
• Kev txheeb xyuas qhov tseeb:Txheeb xyuas qhov tseeb ntawm cov kos npe digital tag nrho los ntawm daim ntawv pov thawj cog lus mus rau daim ntawv pov thawj hauv paus.

Qhov yuav tsum tau ua ua ntej rau kev siv kev txheeb xyuas hauv zos yog tias qhov chaw them hluav taws xob tau teeb tsa daim ntawv pov thawj hauv paus sib xws - feem ntau yog daim ntawv pov thawj V2G hauv paus CA uas muab los ntawm tus neeg teb xov tooj PKI, thiab qee zaum, daim ntawv pov thawj CA hauv paus ntawm MSP (nrog rau qhov sib piv ntawm daim ntawv thov tsawg).

2. Kev txheeb xyuas online ntawm qhov xwm txheej tshem daim ntawv pov thawj

Ib feem ntawm cov txheej txheem txheeb xyuas yog nyob ntawm kev sib tham hauv online, thiab kev txheeb xyuas qhov xwm txheej ntawm daim ntawv pov thawj raug tshem tawm yog ib qho ntawm cov txheej txheem tseem ceeb. Lub chaw them nqi yuav pib nug rau tus neeg teb OCSP uas tau teeb tsa ua ntej hauv daim ntawv pov thawj kom paub tseeb tias ob hom ntawv pov thawj hauv qab no tsis tau raug tshem tawm:

• Daim Ntawv Pov Thawj CPO Sub CA (siv tau rau ob qho tib si ISO 15118-2 thiab ISO 15118-20 cov qauv);
• Daim ntawv pov thawj cog lus (tsuas yog siv rau tus qauv ISO 15118-20);

3. Kev txheeb xyuas qhov xwm txheej ntawm tus account them nqi

Tom qab them nqi tiav lawm, lub kaw lus yuav ua tiav cov txheej txheem los ntawm kev sib pauv cov ntaub ntawv mus rau kev txais nyiaj: Tom qab txheeb xyuas qhov siv tau ntawm daim ntawv pov thawj, CPO yuav lees paub qhov xwm txheej siv tau ntawm daim ntawv cog lus them nqi ntawm tus neeg siv. Lub kaw lus yuav rho tawm tus lej ID ntawm tus neeg muab kev pabcuam los ntawm tus lej cim tus account networking ntawm lub tsheb (EMAID), thiab CPMS yuav txuas MSP sib xws nrog tus lej ID no los txheeb xyuas tias tus account tsis nyob hauv lub xeev raug ncua lossis raug tshem tawm.

4. Cov txheej txheem them nqi pib lawm

Tom qab paub meej tias lub tsheb fais fab yog leej twg, lub tsheb thiab chaw them hluav taws xob yuav ua raws li cov txheej txheem sib pauv lus ntawm ISO 15118 tus qauv, sib tham txog cov kev teeb tsa them thiab lub sijhawm, thiab pib ua haujlwm them hluav taws xob.

Yuav kom ua tiav qhov PnC (Plug&Charge) plug thiab charge function, nws yog ib qho tsim nyog yuav tsum tau teeb tsa ua ntej, khaws cia, thiab txheeb xyuas daim ntawv pov thawj cog lus, thiab paub meej tias cov khoom siv encrypted tau xa mus rau sab hauv ntawm lub tsheb kawg (EV) thiab pile kawg (EVSE).

Raws li tau hais los saum toj no, hauv TLS protocol system:TLS 1.2:hloov kho rau ISO 15118-2;TLS 1.3:Sib xws nrog ISO 15118-20; Ob tog sib txuas lus yuav tsum muaj ob hom ntaub ntawv tseem ceeb:Cov ntaub ntawv qhia txog tus kheejthiabcov ntaub ntawv ntseeg siabNtawm lawv, qhov chaw khaws cia tseem ceeb khaws cia tus yuam sij ntiag tug ntawm lub cuab yeej thiab daim ntawv pov thawj nplooj ntawv sib xws, uas yog siv los ua pov thawj "kev raug cai ntawm tus kheej"; Cov khoom muag ntawm kev ntseeg siab khaws cov ntawv pov thawj CA ntseeg siab (cov khoom siv ntseeg siab), uas yog siv los txheeb xyuas qhov tseeb ntawm daim ntawv pov thawj ntawm lwm tus neeg thiab teb cov lus nug "kev ntseeg siab ciam teb".
