Iko Evolution yeEV Kuchaja Protocol: Kuenzanisa Ongororo yeOCPP 1.6 uye OCPP 2.0

Kukurumidza kukura kweMagetsi Mota yekuchaja zvivakwazvave kudikanwa nemaitiro ekutaurirana maprotocol kuti ave nechokwadi chekudyidzana pakati peEV Charging Stations uye yepakati manejimendi masisitimu. Pakati pezvibvumirano izvi, OCPP (Open Charge Point Protocol) yabuda sechiyero chepasi rose. Ichi chinyorwa chinoongorora misiyano mikuru pakati peOCPP 1.6 neOCPP 2.0, ichitarisa maitiro avo paEV Charger tekinoroji, kunyatsochaja, uye kubatanidzwa nezviyero zvemazuva ano seCCS (Combined Charging System), GB/T, uye DC yekuchaja nekukurumidza.

1. Protocol Architecture uye Communications Models

OCPP 1.6, yakaunzwa muna 2017, inotsigira ese SOAP (pamusoro peHTTP) uye JSON (pamusoro peWebSocket) mafomati, zvichiita kuti kutaurirana kunoshanduka pakatiWallbox Chargeruye nechepakati masisitimu. Yayo asynchronous messaging modhi inobvumiraEV Kuchaja Zviteshikubata mashandiro akaita seyechokwadi, transaction manejimendi, uye firmware zvigadziriso.

OCPP 2.0.1(2020), ichangoburwa iteration, inotora chivakwa chakasimba chine chengetedzo yakawedzerwa. Inoraira HTTPS yekukurukurirana yakavharidzirwa uye inounza zvitupa zvedhijitari zvehuchokwadi hwemudziyo, kugadzirisa kusasimba mushanduro dzekutanga. Kukwidziridzwa uku kwakakosha kuneDC inokurumidza kuchaja zviteshi, uko kutendeseka kwedata uye chaiyo-nguva yekutarisa yakakosha.

2. Smart Charging uye Energy Management

Chinhu chakasarudzika cheOCPP 2.0 ndeyemberi kwayoSmart Chargingkugona. Kusiyana neOCPP 1.6, iyo inopa chiyero chekuenzanisa, OCPP 2.0 inobatanidza simba rekutonga masimba (EMS) uye inotsigira Vehicle-to-Grid (V2G) matekinoroji. Izvi zvinobvumiraEV Chargerkugadzirisa mitengo yekuchaja zvichienderana nekudiwa kwegridi kana kuwanikwa kwesimba rinowanikwazve, kusimudzira kugovera kwesimba paEV Charging Stations.

Semuyenzaniso, Wallbox Charger inoshandisa OCPP 2.0 inogona kukoshesa kuchaja panguva yekusakwira-peak kana kuderedza simba panguva yekusangana kwegridi, kuwedzera kushanda zvakanaka kwevese pekugara nekutengesa.Magetsi Mota yekuchaja setups.

3. Chengetedzo uye Kutevedzera

Nepo OCPP 1.6 ichitsamira pamatanho echokwadi echokwadi, OCPP 2.0 inosuma yekupedzisira-kusvika-kumagumo encryption uye siginecha yedhijitari yekuvandudzwa kwefirmware, kuderedza njodzi senge kusingatenderwe kuwana kana kukanganisa. Izvi zvinonyanya kukosha kuneCCS uye GB/T-inoenderana zviteshi, iyo inobata data remushandisi ane hanya uye yakakwirira-simba DC transaction.

4. Enhanced Data Models uye Kushanda

OCPP 2.0inowedzera data modhi kutsigira yakaoma kuchaja mamiriro. Inounza mhando nyowani dzemeseji yekuongorora, kuchengetedza manejimendi, uye chaiyo-nguva yekurekodha mamiriro, ichigonesa granular kutonga pamusoro.EV Kuchaja Zviteshi. Semuenzaniso, vashandisi vanogona kuongorora kure kure kukanganisa mukatiDC inokurumidza kuchaja zvikamukana kugadzirisa zvigadziriso zveWallbox Charger pasina onsite kupindira.

Kusiyana neizvi, OCPP 1.6 inoshaya tsigiro yemuno ye ISO 15118 (Plug & Charge), muganho wakatarwa muOCPP 2.0 kuburikidza nekubatanidzwa kusina musono neichi chiyero. Kufambira mberi uku kunorerutsa chokwadi chemushandisi paCCS uye GB/T zviteshi, zvichiita kuti “plug-and-charge” zviitiko.

5. Kuenderana uye Kutorwa Kwemusika

OCPP 1.6 inoramba yakagamuchirwa zvakanyanya nekuda kwekukura kwayo uye kuenderana nemasisitimu enhaka, kusanganisira GB/T-based network muChina. Nekudaro, kusawirirana kweOCPP 2.0 neshanduro dzekutanga kunoisa matambudziko ekukwidziridzwa, zvisinei neayo epamusoro maficha senge rutsigiro rweV2G uye yepamusoro mitoro kuenzanisa.

Mhedziso

Shanduko kubva kuOCPP 1.6 kuenda kuOCPP 2.0 inoratidza kusvetuka kwakakosha muMagetsi Mota yekuchaja tekinoroji, inotungamirwa nezvido zvekuchengetedza, kudyidzana, uye smart manejimendi emagetsi. Nepo OCPP 1.6 inokwana kuita zvekutanga EV Charger mashandiro, OCPP 2.0 yakakosha kune ramangwana-proofing EV Kuchaja Zviteshi, kunyanya izvo zvinotsigira.DC inokurumidza kuchaja, CCS, uye V2G. Sezvo indasitiri inoshanduka, kutora OCPP 2.0 kuchave kwakakosha kuti ienderane nezviyero zvepasi rose uye kuwedzera ruzivo rwevashandisi kuWallbox Charger uye nzvimbo dzekuchaja veruzhinji.
