IV. Ntlafatso ea nako e tlang ea OCPP
1. Melemo ea OCPP
OCPP ke protocol e sa lefelloeng le e bulehileng, hape ke mokhoa o atlehang oa ho rarolla khokahano ea qubu ea ho tjhaja, 'me e se e tumme le ho sebelisoa linaheng tse ngata lefatšeng ka bophara, khokahano ea nako e tlang lipakeng tsa lits'ebeletso tsa opareitara e tla ba le puo ea ho buisana.
Pele ho fihla OCPP, moetsi e mong le e mong oa poso o tjhajang o ile a iketsetsa protocol ea hae ea ho hokela morao-rao, ka hona a notlela basebelisi ba poso ba lefisang moetsi a le mong oa poso. Hona joale, hoo e batlang e le baetsi bohle ba lisebelisoa ba tšehetsa OCPP, basebetsi ba poso ba lefisang ba lokolohile ho khetha lisebelisoa ho tsoa ho morekisi ofe kapa ofe, ho etsa hore 'maraka o be le tlhōlisano.
Ho joalo le ho beng ba thepa / likhoebo; ha ba reka seteishene sa ho tjhaja seo e seng sa OCPP kapa konteraka le CPO eo e seng ya OCPP, ba notlellwa seteisheneng se itseng sa ho tjhaja le ho tjhaja opareitara ya poso. Empa ka lisebelisoa tsa ho tjhaja tse lumellanang le OCPP, beng ba matlo ba ka lula ba ikemetse ho bafani ba bona. Beng ba matlo ba lokolohile ho khetha CPO e nang le tlholisano, e theko e phahameng kapa e sebetsang hantle. hape, ba ka atolosa marang-rang a bona ka ho kopanya lisebelisoa tse fapaneng tsa ho tjhaja poso ntle le ho qhaqha meaho e teng.
Ehlile, molemo o ka sehloohong oa li-EV ke hore bakhanni ba EV ha ba hloke ho itšetleha ka opareitara e le 'ngoe ea ho tjhaja kapa mofani oa thepa ea EV. Joalo ka liteishene tsa ho tjhaja tsa OCPP tse rekiloeng, bakhanni ba EV ba ka fetohela ho li-CPO/EMP tse betere. ea bobeli, empa molemo haholo bohlokoa ke bokhoni ba ho sebelisa e-mobility roaming.
