OCPP - Vhura Charge Point Protocol kubva 1.5 kusvika 2.1 muEV kuchaja

Sezvinoratidzwa pazasi, kubva kuOCPP1.5 kusvika kune yazvino OCPP2.0.1

Nekuda kwekuti kune maprotocol akawandisa evaridzi muindasitiri kutsigira ruzivo rwesevhisi yakabatana uye kubatanidza kwekushanda pakati pemasevhisi akasiyana-siyana, OCA yakatungamira mukugadzira yakavhurika protocol OCPP1.5. SIPO inoganhurirwa neayo maprotocol constraints uye haigone kuwanda uye nekukurumidzira kukurumbira.

OCPP 1.5 inotaurirana nepakati masisitimu kuburikidza neSOAP protocol yakavakirwa paHTTP protocol yekushandisa mapoinzi ekuchaja Inotsigira mabasa anotevera: Mabatirwo emunharaunda uye ari kure, kusanganisira kuyera mabhiri.

OCPP 1.6J (JSON pamusoro peWebSockets)

Nepo iyo yekare SOAP vhezheni isingachashandi,OCPP 1.6Jinoramba iri shanduro inonyanya kushandiswa. InoshandisaJSON pamusoro peWebSockets (WSS), iyo inobvumira kutaurirana kwakazara-duplex. Kusiyana neHTTP-based SOAP, WSS inogonesa sevha (CSMS) kutanga mirairo (seRemoteStartTransaction) kune charger kunyangwe charger iri kuseri kweNAT firewall.

OCPP 2.0 (JSON)

OCPP 2.0, yakaburitswa muna 2018, inovandudza mashandiro ekutengeserana, inowedzera kuchengetedzeka, manejimendi ekushandisa: inowedzera smart kuchaja mashandiro, kune topologies ine simba rekutonga masisitimu (EMS), vatongi venzvimbo, uye yeEVs ine integrated smart kuchaja, zviteshi zvekuchaja uye yekuchaja chiteshi manejimendi masisitimu. InotsigiraISO 15118: Plug uye Tamba uye Smart Kuchaja zvinodiwa pamotokari dzemagetsi.

OCPP 2.0.1 (JSON)

OCPP 2.0.1 ndiyo yazvino vhezheni, yakaburitswa muna 2020. Inopa maitiro matsva nekuvandudzwa kwakafanana nerutsigiro rwe ISO15118 (Plug uye Play), chengetedzo yakawedzerwa uye kuita kwakagadziridzwa kwese.

OCPP Shanduro Kuenderana

OCPP1.x inowirirana neshanduro dzakaderera, OCPP1.6 inopindirana neOCPP1.5, OCPP1.5 inopindirana neOCPP1.2.

OCPP2.0.1 haienderani neOCPP1.6, OCPP2.0.1 kunyangwe zvimwe zviri mukati meOCPP1.6 zvinewo, asi chimiro che data chave chakasiyana zvachose nechakatumirwa.

OCPP 2.0.1 protocol

1, Musiyano pakati peOCPP 2.0.1 neOCPP 1.6

Kuenzaniswa neshanduro dzepakutanga dzakadai seOCPP 1.6, OCPP 2.0. 1 ine kuvandudzwa kukuru munzvimbo dzinotevera:

a. Kuchengetedzeka kwakavandudzwa

OCPP 2.0.1: Iyo Chengetedzo & Yechishandiso Management Kuwedzeredza

OCPP 2.0.1 haisi kumashure inoenderana ne1.6J nekuda kwekugadziriswa kwakazara kweiyo data data. Kuvandudza kwayo kwakakosha ndiko kuiswa kwevatatu vanosungirwaSecurity Profiles:

1. Chengetedzo Profile 1:TLS ine Basic Authentication (Pasiwedhi).

2. Chengetedzo Profile 2:TLS ine Client-side Sitifiketi (yepamusoro chengetedzo).

3. Chengetedzo Profile 3:TLS ine Client-side Sitifiketi uye Hardware Security Module (HSM) rutsigiro.

Uyezve, inotsiva iyo yakaganhurirwaKurova kwemoyomichina ine yakazaraDevice Model. Izvi zvinoshandisa standardizedChikamuuyeVariablechimiro chekutarisa zvese kubva kumhanya kwe fan kusvika kune tembiricha yemukati, zvakanyanya kuvandudza kure diagnostics.

b.Kuwedzera Zvitsva

OCPP2.0.1 inowedzera zvinhu zvitsva zvakawanda, zvinosanganisira hungwaru hwekuchaja manejimendi, uye neruzivo rwakadzama rwemharidzo nekuongorora.

c. More Flexible Design

OCPP2.0.1 yakagadzirwa kuti ive yakanyanya kuchinjika kuti isangane nezvinodiwa zvemamwe maapplication akaoma uye akasiyana.

d. Kurerutsa Code

OCPP2.0.1 inorerutsa kodhi, zvichiita kuti zvive nyore kushandisa software.

OCPP2.0.1 firmware update yakawedzera siginecha yedhijitari, kudzivirira kudhawunirodha firmware hakuna kukwana, zvichikonzera kukundikana kwe firmware update.

Muchishandiso chinoshanda, OCPP2.0.1 protocol inogona kushandiswa kuona kure kure kwekuchaja murwi, chaiyo-nguva yekutarisisa mamiriro ekuchaja, chokwadi chemushandisi uye mamwe mabasa, ayo anovandudza zvakanyanya kushandiswa kwemichina yekuchaja, kunyatsoshanda uye kuchengeteka.OCPP2.0.1 tsanangudzo uye mabasa kupfuura 1.6 shanduro yevakawanda, kukura kwekuoma kwakawedzerawo.

2, OCPP2.0.1 sumo yebasa

OCPP 2.0.1 protocol ndiyo yazvino vhezheni yeOCPP protocol. Kuenzaniswa neOCPP 1.6, OCPP 2.0.1 protocol yakagadzirisa zvakawanda uye optimizations. Izvo zvikuru zviri mukati zvinosanganisira:

•Kutumirwa kweMessage:OCP 2.0.1 inowedzera mhando dzemeseji itsva uye inogadziridza mafomati ekare meseji kuti ivandudze mashandiro nekuita.

•Digital Certificates:MuOCPP 2.0.1, zvitupa zvedhijitari-zvakavakirwa nzira dzekuchengetedza dzakaunzwa kuti dzipe kuomarara kwechigadzirwa chechokwadi uye kudzivirira meseji yekuvimbika. Uku ndiko kuvandudzwa kwakakosha pamusoro peOCPP1.6 nzira dzekuchengetedza.

•Data Model:OCPP 2.0.1 inogadziridza iyo data modhi kuti ibatanidze tsigiro yemhando nyowani dzemidziyo uye maficha.

•Device Management:OCPP 2.0.1 inopa mamwe akazara manejimendi manejimendi mabasa, kusanganisira dhizaini kumisikidza, kugadzirisa matambudziko, software inogadziridza, nezvimwe.

•Component modhi:OCPP 2.0.1 inosuma imwe inoshanduka-shanduka chikamu modhi iyo inogona kushandiswa kutsanangura zvakanyanya kuomesesa kuchaja michina uye masisitimu. Izvi zvinobatsira kugonesa zvimwe zvepamberi sengeV2G (Motokari kuenda kuGridhi).

•Smart kuchaja:Yepamberi Smart Kuchaja & ISO 15118 Kubatanidzwa, Musiyano uri pakati pe1.6 uye 2.0.1 mukuchaja smart wakakosha. Nepo 1.6J ichitsamira pane zvakakoshaChargingProfiles, OCPP 2.0.1 natively inotsigiraISO 15118kuburikidza nenzira yekupfuura.

Izvi zvinogonesaPlug & Charge (PnC): Iyo EVSE inoita segedhi, ichibvumira iyo EV kuchinjanisa zvitupa zvedhijitari zvakananga neiyo backend yekuzvisimbisa otomatiki. Hapana makadhi eRFID kana mapurogiramu anodiwa. Izvi zvinoisawo hwaroV2G (Motokari-kuenda-Gridhi), inobvumira bidirectional simba rekuyerera manejimendi zvichibva pane grid frequency uye kugona.

•Kuzivikanwa Kwemushandisi uye Mvumo:OCPP2.0.1 inopa yakavandudzwa yekuziva mushandisi uye nzira dzemvumo, inotsigira akawanda nzira dzechokwadi dzevashandisi, uye inoisa mberi zvinodiwa zvepamusoro zvekuchengetedza data remushandisi.
