I. OCPP Protocol

1. Zita rakazara reOCPP iOpen Charge Point Protocol, inova protocol yemahara uye yakavhurika yakagadzirwa neOCA (Open Charge Alliance), sangano riri muNetherlands.charger yemota yemagetsi yebhokisi remadziro Protocol (OCPP) inoshandiswa pakutaurirana kwakabatana pakati pezviteshi zvekuchaja (CS)charger yemota yemagetsi yebhokisi remadzirouye chero sisitimu yekutarisira nzvimbo dzekuchaja (CSMS). Iyi protocol architecture inotsigira kubatana kweCSMS yemupi webasa rekuchaja nechero nzvimbo dzekuchaja. Mabhenefiti eOCPP protocol: yakavhurika uye yakasununguka kushandisa, inodzivirira kuvharirwa kune mupi mumwe chete (puratifomu yekuchaja), inoderedza nguva/kushanda nesimba uye matambudziko eIT.

2. Shanduro huru dzeprotocol yeOCPP

OCPP1.2(SIPO) OCPP1.5(SIPO) OCPP1.6(SIPO/JSON)

OCPP2.0.1 (JSON)

SOAP inogumira nekuda kwezvirambidzo zvayo zveprotocol, haigone kuve nehuwandu hwakawanda hwekusimudzira nekukurumidza; JSON vhezheni yekutaurirana kweWebSocket, inogona kutumirana data mune chero network, maprotocol anonyanya kushandiswa pamusika i1.6J vhezheni, OCPP2.0.1 ndiyo 2018 yakabuda muprotocol iri kukurudzira kushandiswa kwegwara remangwana.
