Tsananguro yakadzama yekushanda kwehunyanzvi hwePnC Plug&Charge sevhisi yekuchaja -1

1, Chikamu chekuvaka kuvimbana pakati pemotokari nenzvimbo dzekuchaja

Kusimbiswa kwehunhu:Nzvimbo yekuchaja inosimbisa kuzivikanwa kwayo kuburikidza nechitupa cheSECC (Supply Equipment Communication Controller), ukuwo mota ichishandisa chitupa chemudzi cheV2G chakagadziriswa kare (Trust Anchor) chefactory kuti isimbiswe. Kuti zvisaitike zvekunyepedzera, sisitimu iyi yakaunza OCSP (Online Certificate Status Protocol). Muchiyero cheISO15118-20 chazvino, kusimbiswa kwekubviswa kwezvitupa panguva chaiyo kunodiwa kune zvese zvitupa (kusanganisira Sub CA neLeaf certificates) kuitira kuve nechokwadi chekuti zvese zvinongedzo zvekutaurirana zviri pasi pekutariswa kwakasimba kwekutevedzera mitemo.

Padanho rino, mota (EV) nenzvimbo yekuchaja (EVSE) vanobatana maoko zvichibva pane ISO 15118 protocol. Mushure mekupedza basa rekuisa pfuti uye kuvaka link yekutaurirana yedhijitari, mapato ese ari maviri achataurirana kuti aone shanduro yekushandisa yeTransport Layer Security Protocol (TLS):

• TLS 1.2inoshandiswa muchiyero cheISO 15118-2;
• Paunenge uchishandisaISO 15118-20mwero,TLS 1.3inotorwa;

1. Nzvimbo yekuchaja inopa cheni yayo yezvitupa kumota yemagetsi, kusanganisira chitupa cheSupply Equipment Communication Controller (SECC) uye chitupa cheCharge Operator (CPO) Intermediate Certificate Authority (Sub CA), kuti ipedzise kusimbiswa kwechiratidzo chemotokari.
2. Mota dzemagetsi dzinoshandisa ma trust anchors akaiswa kare (kureva kuti V2G root certificates anoiswa kare mota isati yasvika kuvashandisi) kuti dzisimbise cheni yese yecertificate inotumirwa nezviteshi zvekuchaja.
3. Mota dzemagetsi dzichaongororwa kuti dzine zvitupa zvakabviswa here: Pasi pemutemo weISO 15118-2, zvitupa zveSECC zvakagadzirwa kwenguva pfupi (mwedzi 2-3), uye mamiriro ekuti zvitupa zveCPO Sub CA zvinoongororwa kuburikidza neOnline Certificate Status Protocol (OCSP); Mutemo weISO 15118-20 unoda kuti zvitupa zvese zviongororwe kuti zvine zvitupa zvakabviswa here kuburikidza neOCSP.
4. Mushure mekunge matanho ese ekusimbisa aitwa, mota yemagetsi inogona kusimbisa humbowo hwenzvimbo yekuchaja yakavimbika, uye data rese rekutaurirana richatumirwa uchishandisa nzira dzakavharirwa.

2, Danho rekutaurirana nezvenzira yekuzivikanwa kwehunhu

Pfungwa dzakasiyana pakati peEIM nePnC: Iyi protocol inorambidza zvachose kuita "dual identity recognition" kune vashandisi. Kana zvikaonekwa kuti mushandisi akatanga nemaoko kuburikidza neRFID kana App (EIM mode), nzvimbo yekuchaja inofanira kumisa otomatiki maitiro ePnC triggering kudzivirira njodzi yebhizinesi yekubhadharisa kaviri.

Iyo ISO 15118 standard inotsanangura nzira mbiri dzekuzivikanwa kwechikamu chekuchaja:

• 1. Nzira dzeKuziva Kunze (EIM):kufukidza makadhi eRadio Frequency Identification (RFID), makadhi echikwereti, maapplication enharembozha, maQR code, nezvimwewo;
• 2. Puragi & Chaja:Nzira yekusimbisa zvizere yakavakirwa pazvitupa.

Chirambidzo chikuru:Nzvimbo dzekuchaja hadzifanirwe kuita mbiri yekuziva kuti munhu ari kushandisa chii. Kana mushandisi akapedzisa kusimbiswa achishandisa nzira dzekunze dzakadai seRFID card asati abatanidza pfuti yekuchaja, nzvimbo yekuchaja inofanira kumisa plug neplay function zvichikonzera; Zvikasadaro, zvinogona kukonzera kuti mota irambe ichisimbiswa kuburikidza nechitupa chechibvumirano, zvichikonzera njodzi yekubhadhariswa kaviri.

3, Danho rekusimbisa hunhu hwemotokari

Mushure mekunge sisitimu yasarudza nzira yekuchaja yeplug and play, mota yemagetsi inoendesa chitupa chechibvumirano pamwe nechitupa cheMobile Service Provider (MSP) Sub CA kunzvimbo yekuchaja. Zvitupa zviri pamusoro apa zvakabatanidzwa mucheni yakazara yezvitupa, uye maitiro ekusimbisa hunhu hwepakati anotangwa zviri pamutemo. Backend ichaita cheki dzakawanda dzekuchengetedza kuti ive nechokwadi chekuti nguva dzekuchaja dziri pamutemo, kushanda kwemaakaundi ekubhadhara, uye kudzivirira njodzi yekunyengedzwa kwehunhu hwemotokari.

Kuti vadzivise kurwiswa kwekudzokorora (kureva ma hackers anobata mameseji ekubvumidza uye otumira kakawanda), sisitimu iyi inogadzira kodhi yekupikisa ye128 bit. Mota inofanira kushandisa kiyi yakavanzika kusaina kodhi yekupikisa, uye nzvimbo yekuchaja ichaita ongororo yesaini yemhando ye millisecond munharaunda ichishandisa kiyi yeruzhinji yechitupa chekondirakiti. Iyi encryption isina kufanana inovimbisa kusiyana uye kusaramba mvumo yekukurumidza.

1. Kusimbiswa kwechokwadi kwemapombi ekuchaja pamacheni ezvitupa

Nzvimbo yekuchaja kana kuti CPO backend system inofanirwa kupedzisa ongororo mbiri dzinotevera:

• Kusimbiswa kwechokwadi:Simbisa kuti zvitupa zvese zviri muchikamu chezvitupa zviri mukati menguva yazvo yekushanda;
• Kusimbiswa kwechokwadi:Simbisa kuti siginecha yedhijitari yakazara kubva pachitupa chechibvumirano kusvika pachitupa chemudzi ndeyechokwadi here.

Chinodiwa pakuita kuti nzvimbo yekuchaja ive ne root certificate inoenderana nayo - kazhinji V2G root CA certificate inopihwa nePKI operator, uye mune dzimwe nguva, MSP's root CA certificate (ine chiyero chidiki chekushandisa).

2. Kusimbiswa kwemamiriro ekubviswa kwechitupa online

Chikamu chemaitiro ekusimbisa chinoenderana nekutaurirana online, uye kusimbiswa kwemamiriro ekubvisa chitupa ndeimwe yenzira huru. Nzvimbo yekuchaja ichatanga kubvunza kune anopindura OCSP akatoiswa muchitupa kuti vasimbise kuti mhando mbiri dzechitupa hadzina kubviswa:

• Chitupa cheCPO Sub CA (chinoshanda kune ese ari maviri ISO 15118-2 uye ISO 15118-20 standards);
• Chitupa chechibvumirano (chinoshanda chete pachiyero cheISO 15118-20);

3. Kusimbiswa kwemamiriro eakaundi yekubhadhara

Kana kubhadharisa kwapera, sisitimu inopedzisa otomatiki maitiro kubva pakuchinjana data kusvika pakugamuchira mari: Mushure mekusimbisa kushanda kwechitupa, CPO ichasimbisa mamiriro ekushanda kwechibvumirano chekubhadhara chemushandisi. Sisitimu iyi ichabvisa ID yemupi webasa kubva ku identifier yeakaundi ye networking (EMAID), uye CPMS ichabatanidza MSP inoenderana neID iyi kuratidza kuti account haisi mumamiriro ekumiswa kana kukanzurwa.

4. Maitiro ekuchaja atangwa

Mushure mekusimbisa kuzivikanwa kwemotokari yemagetsi, mota nenzvimbo yekuchaja zvinotevedzera maitiro ekuchinjana mameseji eISO 15118 standard, kutaurirana nezvematanho ekuchaja nenguva, uye kutanga basa rekuchaja zviri pamutemo.

Kuti upedze basa rePnC (Plug&Charge) plug and charge, zvakakosha kuti uise, uchengetedze, uye usimbise chitupa chechibvumirano, uye usimbise sisitimu yezvinhu zvakavharidzirwa yakaiswa mukati memotokari (EV) nemotokari (EVSE).

Sezvambotaurwa pamusoro apa, muTLS protocol system:TLS 1.2:yakagadziridzwa kuti ienderane neISO 15118-2;TLS 1.3:Inoenderana neISO 15118-20; Mapato ese ari maviri ekutaurirana anofanirwa kuve nemhando mbiri dzedata guru:Zvinhu zvekuzivikanwauyezvinhu zvekuvimbaPakati pazvo, key repository inochengeta kiyi yakavanzika yemudziyo uye leaf certificate inoenderana nayo, iyo inoshandiswa kuratidza "kuzivikanwa kwechokwadi"; Trust inventory inochengeta trusted CA certificates (trust anchors), iyo inoshandiswa kusimbisa kushanda kwecertificate yemumwe munhu uye kupindura mubvunzo we "trust boundary".
