Murwi wekuchaja–OCPP protocol yekutaurirana yekuchaja

1. Nhanganyaya kune protocol yeOCPP

Zita rakazara reOCPP ndiOpen Charge Point Protocol, inova protocol yemahara uye yakavhurika yakagadzirwa neOCA (Open Charging Alliance), sangano riri muNetherlands. Open Charge Point Protocol (OCPP) Open Charge Point Protocol inoshandiswa kune mhinduro dzekutaurirana dzakabatana pakati pezviteshi zvekuchaja (CS) nechero system yekutonga zviteshi zvekuchaja (CSMS). Iyi protocol architecture inotsigira kubatana kwesystem yepakati pechero mupi webasa rekuchaja nemapombi ese ekuchaja, uye inonyanya kushandiswa kugadzirisa matambudziko akasiyana-siyana anokonzerwa nekutaurirana pakati pemanetwork ekuchaja epachivande. OCPP inotsigira manejimendi ekutaurirana asina muganho pakati pezviteshi zvekuchaja uye masisitimu epakati ekutonga emutengesi wega wega. Hunhu hwekuvharwa kwemanetwork ekuchaja epachivande hwakakonzera kusagadzikana kusingakoshi kune vazhinji vevaridzi vemotokari dzemagetsi nevatariri vezvivakwa mumakore mazhinji apfuura, zvichikonzera kufona kwakapararira muindasitiri yese kwemodhi yakavhurika. Mabhenefiti eprotocol yeOCPP: yakavhurika kushandiswa mahara, kudzivirira kuvharirwa kwemutengesi mumwe chete (puratifomu yekuchaja), kuderedza nguva yekubatanidza/mutoro webasa nematambudziko eIT.

2. Nhanganyaya yekugadzirwa kweshanduro yeOCPP

Muna 2009, kambani yekuDutch ElaadNL yakatanga kuumbwa kweOpen Charging Alliance, iyo inonyanya kuita basa rekusimudzira open charging protocol OCPP uye open smart charging protocol OSCP. OCPP yava neOCA; inogona kutsigira marudzi ese ematekinoroji ekuchaja.

3. Sumo yeshanduro yeOCPP

Sezvakaratidzwa pazasi, kubva kuOCPP1.5 kusvika kuOCPP2.0.1 yazvino

(1) OCPP1.2 (SIPO)

(2)OCPP1.5 (SIPO)

Sezvo paine maprotocol akawanda epachivande muindasitiri asingakwanise kutsigira ruzivo rwebasa rwakabatana uye kubatana kwekushanda pakati pemasevhisi akasiyana evashandisi, OCA yakatungamira mukugadzira protocol yakavhurika OCPP1.5. SOAP inoganhurirwa nezvirambidzo zveprotocol yayo uye haigone kusimudzirwa nekukurumidza padanho guru.

OCPP 1.5 inotaurirana nesystem yepakati kuburikidza neprotocol yeSOAP kuburikidza neHTTP kuti ishandise nzvimbo dzekuchaja. Inotsigira zvinotevera: Kutengeserana kwemuno uye kwakatangwa kure, kusanganisira kuyera kwekubhadhara

(3) OCPP1.6 (SOAP/JSON)

OCPP vhezheni 1.6 inowedzera kushandiswa kwefomati yeJSON uye inowedzera kugona kwekuchaja kwakangwara. Shanduro yeJSON inotaurirana kuburikidza neWebSocket, iyo inogona kutumirana data mune chero nzvimbo yenetwork. Protocol inonyanya kushandiswa pamusika parizvino ivhezheni 1.6J.

Inotsigira data reJSON format zvichibva pawebhusockets protocol yekuderedza traffic yedata (JSON, JavaScript Object Notation, ifomati yekuchinjana data yakareruka) uye inobvumira kushanda pama network asingatsigire charging point packet routing (senge internet yeruzhinji). Smart charging: load balancing, central smart charging uye local smart charging. Rega charging point itumirezve ruzivo rwayo (zvichibva paruzivo rwecharging point iripo), senge last metering value kana mamiriro echarging point.

(4) OCPP2.0 (JSON)

OCPP2.0, yakaburitswa muna 2018, inovandudza mashandiro ekutengeserana, inowedzera kuchengetedzeka, uye manejimendi yemidziyo: inowedzera mabasa ekuchaja akangwara, ekugadzirisa magadzirirwo ane masisitimu ekutonga simba (EMS), vanodzora vemunharaunda, uye ekuchaja mota dzemagetsi akangwara, Topology yezviteshi zvekuchaja uye masisitimu ekutarisira zviteshi zvekuchaja. Inotsigira ISO 15118: Zvinodiwa zvekuchaja nekubatanidza uye zvekushandisa nekuchenjera pamotokari dzemagetsi.

(5) OCPP2.0.1 (JSON)

OCPP 2.0.1 ndiyo vhezheni yazvino, yakaburitswa muna 2020. Inopa maficha matsva nekuvandudzwa kwakadai sekutsigira ISO15118 (plug and play), kuchengetedzeka kwakawedzerwa, uye kuvandudzwa kwese kwese kwekushanda.

Kana muchida kuziva zvakawanda nezveizvi, ndapota musazeza kutibata.
