1, Usoro iwuli ntụkwasị obi n'etiti ụgbọala na ọdụ chaja

Nkwenye njirimara:Ebe a na-ana chaja na-enyocha njirimara ya site na asambodo SECC (Supply Equipment Communication Controller), ebe ụgbọala ahụ na-eji asambodo mgbọrọgwụ V2G nke ụlọ ọrụ mmepụta ihe (Trust Anchor) maka nkwenye obe. Iji gbochie mwakpo adịgboroja asambodo, sistemụ ahụ ewebatala OCSP (Ntanetị Asambodo Ọnọdụ Usoro). Na ọkọlọtọ ISO15118-20 kachasị ọhụrụ, nkwenye nkwụsịtụ oge dị mkpa maka asambodo niile (gụnyere asambodo Sub CA na Leaf) iji hụ na njikọ nkwukọrịta ọ bụla dị n'okpuru nlekọta nrubeisi siri ike.

N'oge a, ụgbọ ala (EV) na ebe a na-achaji (EVSE) na-ama aka dabere na usoro ISO 15118. Mgbe emechara ọrụ itinye egbe ma wulite njikọ nkwukọrịta dijitalụ, akụkụ abụọ ahụ ga-akparịta ụka iji chọpụta ụdị ngwa nke Protocol Nchekwa Layer Transport Layer (TLS):

• TLS 1.2a na-eji ya na ọkọlọtọ ISO 15118-2;
• Mgbe eji yaISO 15118-20ọkọlọtọ,TLS 1.3a na-anabata;

1. Ebe a na-ana chaja na-enye ụgbọ ala eletrik usoro asambodo ya, gụnyere asambodo Onye njikwa nkwukọrịta ngwa ahịa (SECC) na asambodo Onye ọrụ chaja (CPO) Intermediate Certificate Authority (Sub CA), iji mezue nkwenye njirimara nke ụgbọ ala ahụ.
2. Ụgbọala eletriki na-eji ihe nkwado ntụkwasị obi arụnyere (dịka asambodo mgbọrọgwụ V2G nke edobere tupu ebuga ụgbọala nye ndị ọrụ) iji nyochaa usoro asambodo zuru oke nke ọdụ chaja nyefere.
3. A ga-enyocha ọkwa mwepụ asambodo ụgbọala eletrik: Dịka ọkọlọtọ ISO 15118-2 si dị, a na-emepụta asambodo SECC nwere oge nkwado nwa oge (ọnwa 2-3), a na-enyochakwa ọnọdụ mwepụ nke asambodo CPO Sub CA site na Usoro Ọnọdụ Asambodo Ntanetị (OCSP); Ụkpụrụ ISO 15118-20 chọrọ ka asambodo niile nweta nkwenye ọnọdụ mwepụ site na OCSP.
4. Mgbe emechara usoro nyocha niile, ụgbọala eletrik nwere ike ịkwado njirimara a pụrụ ịtụkwasị obi nke ebe a na-akwụ ụgwọ, a ga-ezipụkwa data nkwukọrịta zuru oke na-esote site na iji usoro ezoro ezo.

2, Usoro nkwurịta okwu maka njirimara

Echiche dị n'etiti EIM na PnC: Usoro a machibidoro ime "nchọpụta njirimara abụọ" n'ebe ndị ọrụ nọ. Ọ bụrụ na achọpụta na onye ọrụ amalitela site na RFID ma ọ bụ App (ụdị EIM), ebe a na-akwụ ụgwọ ga-akwụsị usoro mkpalite PnC ozugbo iji zere ihe egwu azụmaahịa nke ịkwụ ụgwọ abụọ.

Ọkọlọtọ ISO 15118 na-akọwa usoro njirimara njirimara abụọ nke oge ịchaji:

• 1. Ụzọ njirimara mpụga (EIM):na-ekpuchi kaadị njirimara redio ugboro ugboro (RFID), kaadị kredit, ngwa mkpanaka, koodu QR, wdg;
• 2. Nkwụnye na Chajị:Usoro nyocha akpaaka zuru oke dabere na asambodo.

Ihe mgbochi bụ isi:Ebe a na-anata ego agaghị egosipụta njirimara abụọ n'ebe ndị ọrụ nọ. Ọ bụrụ na onye ọrụ emechara nyocha site na ụzọ mpụga dịka kaadị RFID tupu ejikọta egbe a na-anata ego, ebe a na-anata ego kwesịrị ịkwụsị ọrụ nkwụnye na egwuregwu; Ma ọ bụghị ya, ọ nwere ike ime ka a na-enye ikike ugboro ugboro site na asambodo nkwekọrịta ahụ, nke na-eduga n'ihe egwu nke ịkwụ ụgwọ ugboro abụọ.

3, Ogbo nkwenye njirimara ụgbọala

Mgbe sistemụ ahụ họpụtasịrị ụdị chaja plọg na play, ụgbọala eletrik na-enyefe asambodo nkwekọrịta na asambodo Sub CA nke na-akwado Onye Na-enye Ọrụ Ekwentị (MSP) na ọdụ chaja. A na-etinye asambodo ndị dị n'elu n'ime usoro asambodo zuru oke, a na-amalitekwa usoro nkwenye njirimara isi n'ihu ọha. Ihe nkwado azụ ga-eme ọtụtụ nyocha nchekwa iji hụ na oge chaja bụ iwu, izi ezi nke akaụntụ ịkwụ ụgwọ, ma gbochie ihe egwu nke adịgboroja njirimara ụgbọala.

Iji gbochie mwakpo mmegharị ugboro ugboro (dịka ọmụmaatụ, ndị na-agba ọsọ mbanye anataghị ikike na-egbochi ozi ikike ma na-eziga ha ugboro ugboro), sistemụ ahụ na-emepụta koodu ịma aka 128 bit na-enweghị usoro. Ụgbọala ahụ ga-eji igodo nkeonwe bịanye aka na koodu ịma aka ahụ, ebe a na-anata chaja ga-eme nkwenye mbinye aka nke ọkwa millisecond n'ógbè ahụ site na iji igodo ọha nke asambodo nkwekọrịta ahụ. Nzochi nzuzo a na-adịghị ahụkebe na-eme ka a ghara ịhụ na ikike ozugbo dị iche ma ghara ịjụ ya.

1. Nkwenye ziri ezi nke ikpo chajị na agbụ asambodo

Ebe a na-ana chaja ma ọ bụ sistemụ azụ CPO kwesịrị imecha nkwenye isi abụọ ndị a:

• Nkwenye nkwenye:Kwenye na asambodo niile dị na usoro asambodo ahụ dị n'ime oge izi ezi ha;
• Nkwenye nke izi ezi:Chọpụta na mbinye aka dijitalụ zuru oke site na asambodo nkwekọrịta ruo na asambodo mgbọrọgwụ dị irè.

Ihe dị mkpa maka itinye nkwenye mpaghara bụ na ebe a na-ana chaja ahaziela asambodo mgbọrọgwụ kwekọrọ - nke na-abụkarị asambodo mgbọrọgwụ V2G nke onye ọrụ PKI nyere, na n'ọnọdụ ụfọdụ, asambodo mgbọrọgwụ CA nke MSP (nwere oke ngwa dịtụ ala).

2. Nkwenye n'ịntanetị nke ọnọdụ mwepụ asambodo

Akụkụ nke usoro nkwenye ahụ dabere na mmekọrịta dị n'ịntanetị, nkwenye ọnọdụ mwepụ asambodo bụkwa otu n'ime usoro ndị bụ isi. Ebe a na-ana chaja ga-amalite ajụjụ nye onye na-aza OCSP nke edobere na asambodo ahụ iji gosi na ewepụbeghị ụdị asambodo abụọ ndị a:

• Asambodo CPO Sub CA (dabara na ọkọlọtọ ISO 15118-2 na ISO 15118-20);
• Asambodo nkwekọrịta (nke dabara naanị na ọkọlọtọ ISO 15118-20);

3. Nkwenye ọnọdụ akaụntụ ịgba ụgwọ

Mgbe emechara ịkwụ ụgwọ ahụ, sistemụ ahụ na-emecha usoro ahụ na akpaghị aka site na mgbanwe data ruo na nnata ego: Mgbe emechara nyocha nke asambodo ahụ, CPO ga-akwado ọnọdụ izi ezi nke nkwekọrịta ịkwụ ụgwọ onye ọrụ. Sistemụ ahụ ga-ewepụta ID onye na-enye ọrụ site na njirimara akaụntụ netwọk ụgbọala (EMAID), CPMS ga-ejikọkwa MSP kwekọrọ na ID a iji chọpụta na akaụntụ ahụ adịghị na steeti a kwụsịtụrụ ma ọ bụ nke a kagburu.

4. Usoro ịchaji amalitela

Mgbe ha kwadochara njirimara nke ụgbọala eletrik ahụ, ụgbọala ahụ na ebe a na-ana chaja ga-eso usoro mgbanwe ozi nke ọkọlọtọ ISO 15118, kparịta ụka na paramita chaja na oge, ma malite ọrụ chaja n'ihu ọha.

Iji mezue ọrụ plọg na chajị PnC (Plug&Charge), ọ dị mkpa ịtọlite, chekwaa, na nyochaa asambodo nkwekọrịta ahụ, ma kwado sistemụ ihe ezoro ezo nke e tinyere n'ime njedebe ụgbọala (EV) na njedebe pile (EVSE).

Dịka ekwuru n'elu, na sistemụ usoro TLS:TLS 1.2:emegharịrị ya ka ọ dabara na ISO 15118-2;TLS 1.3:Dakọtara na ISO 15118-20; Ndị otu nkwukọrịta abụọ ahụ kwesịrị inwe ụdị data isi abụọ:Ihe njirimaranaihe ntụkwasị obiN'ime ha, ebe nchekwa isi na-echekwa igodo nzuzo nke ngwaọrụ ahụ na asambodo akwụkwọ kwekọrọ, nke a na-eji egosi "izi ezi nke njirimara"; Ebe nchekwa ngwaahịa ntụkwasị obi na-echekwa asambodo CA a tụkwasịrị obi (ihe nkwado ntụkwasị obi), nke a na-eji enyocha izi ezi nke asambodo nke onye nke ọzọ ma zaa ajụjụ "ókèala ntụkwasị obi".
