He whakamārama taipitopito mō te kaupapa mahi hangarau o te ratonga utu PnC Plug&Charge -1

1, Te wāhanga hanga whakawhirinaki i waenga i ngā waka me ngā teihana utu

Manatoko tuakiri:Ka manatokohia e te teihana utu tōna tuakiri mā te tiwhikete SECC (Supply Equipment Communication Controller), ā, ka whakamahia e te waka te tiwhikete pakiaka V2G kua whakaritea e te wheketere (Trust Anchor) hei manatoko whakawhiti. Hei ārai i ngā whakaeke tinihanga tiwhikete, kua whakauruhia e te pūnaha te OCSP (Online Certificate Status Protocol). I roto i te paerewa ISO15118-20 hou, he mea whakahau te manatoko whakakorenga wā-tūturu mō ngā tiwhikete katoa (tae atu ki ngā tiwhikete Sub CA me Leaf) kia tino aroturukitia ai ngā hononga whakawhitiwhiti katoa.

I tēnei wā, ka rūrū te waka (EV) me te teihana utu (EVSE) i runga i te kawa ISO 15118. I muri i te otinga o te mahi whakauru pū me te hanga hononga whakawhitiwhiti matihiko, ka whiriwhiri ngā taha e rua ki te whakatau i te putanga tono o te Kawa Haumarutanga Papa Waka (TLS):

• TLS 1.2e whakamahia ana i roto i te paerewa ISO 15118-2;
• Ina whakamahia teISO 15118-20paerewa,TLS 1.3kua whāngaihia;

1. Ka whakaatuhia e te teihana utu tana mekameka tiwhikete ki te waka hiko, tae atu ki te tiwhikete Supply Equipment Communication Controller (SECC) me te tiwhikete Charge Operator (CPO) Intermediate Certificate Authority (Sub CA), hei whakaoti i te manatoko tuakiri pono o te waka.
2. Ka whakamahia e ngā waka hiko ngā punga whakawhirinaki kua tāutahia i mua (arā, ngā tiwhikete pakiaka V2G kua whakatakotoria i mua i te tukunga o te waka ki ngā kaiwhakamahi) hei manatoko i te mekameka tiwhikete katoa i tukuna mai e ngā teihana utu.
3. Ka whakamanahia te mana whakakorenga tiwhikete mō ngā waka hiko: I raro i te paerewa ISO 15118-2, he poto noa te wā whai mana o ngā tiwhikete SECC (2-3 marama), ā, ka manatokohia te mana whakakorenga o ngā tiwhikete CPO Sub CA mā te Online Certificate Status Protocol (OCSP); e hiahiatia ana e te paerewa ISO 15118-20 kia whakamanahia te mana whakakorenga o ngā tiwhikete katoa mā te OCSP.
4. Kia oti ngā mahi manatoko katoa, ka taea e te waka hiko te whakaū i te tuakiri pono o te teihana utu, ā, ka tukuna ngā raraunga whakawhitiwhiti kōrero katoa i muri mai mā te whakamahi i ngā tikanga whakamuna.

2, Wāhanga whiriwhiringa tikanga mō te mōhiotanga tuakiri

Te ariā motuhake i waenga i te EIM me te PnC: Ka āraia rawatia e te kawa te mahi "whakamōhio tuakiri takirua" ki ngā kaiwhakamahi. Mena ka kitea kua tīmata ā-ringa te kaiwhakamahi mā te RFID, mā te Taupānga rānei (aratau EIM), me whakamutu aunoa te teihana utu i te tukanga whakaoho PnC hei karo i te tūponotanga pakihi o te nama tārua.

E rua ngā tikanga mō te mōhio ki te tuakiri o te wā utu e tautuhia ana e te paerewa ISO 15118:

• 1. Ngā Tikanga Tāutu ā-Waho (EIM):e kapi ana i ngā kāri Tautuhi Auautanga Reo Irirangi (RFID), ngā kāri nama, ngā taupānga pūkoro, ngā waehere QR, me ētahi atu;
• 2. Mono me te Utu:He tikanga motuhēhēnga aunoa katoa e hangai ana ki ngā tiwhikete.

Herenga matua:Kaua ngā teihana utu e whakamahi i te tikanga mō te tautuhi tuakiri takirua ki ngā kaiwhakamahi. Mēnā ka oti i te kaiwhakamahi te manatoko mā roto i ngā tikanga o waho pērā i te kāri RFID i mua i te hono i te pū utu, me whakamutu e te teihana utu te whakahohe i te mahi mono-ā-ringa; ki te kore, ka hua ake pea te whakamanatanga maha o te waka mā te tiwhikete kirimana, ka ara ake ai te mōrearea o te nama tārua.

3, Wāhanga manatoko tuakiri waka

I muri i te whiriwhiringa a te pūnaha i te aratau utu mono-ā-ringa, ka tukuna e te waka hiko te tiwhikete kirimana me te tiwhikete tautoko a te Kaiwhakarato Ratonga Waea Pūkoro (MSP) SubCA ki te teihana utu. Ka whakauruhia ngā tiwhikete o runga ake nei ki roto i tētahi mekameka tiwhikete katoa, ā, ka whakarewahia mana te tukanga manatoko tuakiri matua. Ka mahi tahi te pito o muri i ngā tirotiro haumarutanga maha hei whakarite i te ture o ngā wā utu, te mana o ngā kaute nama, me te ārai i te mōrearea o te tinihanga tuakiri waka.

Hei ārai i ngā whakaekenga tukurua (arā, ko ngā kaipahua e hopu ana i ngā karere whakamanatanga me te tuku atu i aua karere i ngā wā katoa), ka whakaputahia e te pūnaha he waehere wero matapōkere 128-moka. Me whakamahi te waka i tētahi kī tūmataiti hei waitohu i te waehere wero, ā, ka whakahaerehia e te teihana utu he manatoko waitohu taumata mirihekona ā-rohe mā te whakamahi i te kī tūmatanui o te tiwhikete kirimana. Mā tēnei whakamunatanga kore-taurite ka whakarite kia motuhake, kia kore ai hoki e whakakorengia te whakamanatanga inamata.

1. Manatoko mana o ngā puranga utu i runga i ngā mekameka tiwhikete

Me whakaoti e te teihana utu, te pūnaha CPO rānei ngā manatoko matua e rua e whai ake nei:

• Manatoko mana:Whakaū kei roto i te wā whai mana ngā tiwhikete katoa i roto i te mekameka tiwhikete;
• Manatoko pono:Manatokohia te mana o te waitohu mamati mekameka katoa mai i te tiwhikete kirimana ki te tiwhikete pūtake.

Ko te whakaritenga mō te whakatinana i te manatoko ā-rohe ko te whakarite i mua i te tiwhikete pakiaka e rite ana ki te teihana utu – ko te tiwhikete CA pakiaka V2G te tikanga i whakaratohia e te kaiwhakahaere PKI, ā, i ētahi wā, ko te tiwhikete CA pakiaka a te MSP ake (me te ōwehenga tono iti).

2. Manatoko ipurangi mō te mana whakakorenga tiwhikete

Ko tētahi wāhanga o te tukanga manatoko e whakawhirinaki ana ki te taunekeneke ipurangi, ā, ko te manatoko mana whakakore tiwhikete tētahi o ngā tukanga matua. Ka tīmata te teihana utu i tētahi patai ki te kaiwhakautu OCSP kua whakaritea i mua i roto i te tiwhikete hei whakaū kāore anō kia whakakorea ngā momo tiwhikete e rua e whai ake nei:

• Tiwhikete CPO Sub CA (e pā ana ki ngā paerewa ISO 15118-2 me ISO 15118-20);
• Tiwhikete kirimana (e pā ana ki te paerewa ISO 15118-20 anake);

3. Manatoko tūnga pūkete nama

Kia oti te utu, ka oti aunoa te tukanga mai i te whakawhiti raraunga ki te whiwhinga moni e te pūnaha: Kia manatokohia te mana o te tiwhikete, ka whakaū te CPO i te mana o te kirimana nama a te kaiwhakamahi. Ka tangohia e te pūnaha te ID kaiwhakarato ratonga mai i te tohu pūkete whatunga waka (EMAID), ā, ka hono te CPMS i te MSP e rite ana ki tēnei ID hei manatoko kāore te pūkete i roto i te āhua whakatārewatia, whakakorea rānei.

4. Kua tīmata te tukanga utu

I muri i te whakaū i te tuakiri o te waka hiko, ka whai te waka me te teihana utu i te tukanga whakawhiti karere o te paerewa ISO 15118, ka whiriwhiri i ngā tawhā utu me te wā, ā, ka tīmata mana te ratonga utu.

Hei whakaoti i te mahi mono me te utu PnC (Plug&Charge), me whakarite i mua, me penapena, me manatoko hoki i te tiwhikete kirimana, me te whakaū i te pūnaha rauemi whakamuna kua whakatinanahia ki roto i te pito waka (EV) me te pito puranga (EVSE).

E ai ki te kōrero i runga ake nei, i roto i te pūnaha kawa TLS:TLS 1.2:i urutau ki te ISO 15118-2;TLS 1.3:Hototahi ki te ISO 15118-20; Me rua ngā momo raraunga matua o ngā rōpū whakawhitiwhiti kōrero e rua:Ngā rauemi tuakirimengā rauemi whakawhirinakiI roto i ēnei, ka rongoatia e te putunga kī te kī tūmataiti o te taputapu me te tiwhikete rau e rite ana, e whakamahia ana hei whakamatau i te "tikanga o te tuakiri"; ka rongoatia e te rarangi whakawhirinaki ngā tiwhikete CA pono (ngā punga whakawhirinaki), e whakamahia ana hei manatoko i te mana o ngā tiwhikete a te rōpū kē, me te whakautu i te pātai "rohe whakawhirinaki".
