1. Umdwebo We-Topology Kagesi
2. Indlela yokulawula ukushaja yesistimu yokushaja
1) Vula ngesandla ugesi we-12V DC ukuze ufake i-EVCC esimweni sokuvula, noma uvuse i-EVCC umaisibhamu sokushaja se-EVifakwe ku-idokhi yokushaja imoto kagesiI-EVCC izobe isiqalisa.
2) Ngemva kokuthi ukuqaliswa kwe-EVCC sekuqediwe, iqala ukuthola isithwali se-CP sedokhi yokushaja.
3) Uma imvamisa yenkampani ye-CP ingeyona i-1kHz, imvamisa yenkampani ye-CP iyaqhubeka nokutholakala. Uma imvamisa yenkampani ye-CP isengakabi yi-1kHz ngemva kwemizuzwana engama-20 yokutholakala, i-EVCC ingena kwimodi yokulala.
4) Uma imvamisa yenkampani yokuthwala i-CP ingu-1kHz, umjikelezo womsebenzi wetheminali yesignali ye-CP yedokhi yokushaja uyatholwa.
5) Uma umjikelezo womsebenzi we-terminal yesignali ye-CP ingu-5%, i-EVCC ikhipha isignali yezinga eliphezulu le-A+ ku-BMS ukuze ivuse i-BMS. Ngemuva kwalokho, i-EVCC kanye ne-SECC yenqwaba yokushaja benza ukuxhawulana kwe-PLC. Uma ukuxhawulana kwehluleka, kubuyela esinyathelweni sesi-2). Uma ukuxhawulana kuphumelela, kungena enkambisweni yokushaja.
6) Uma umjikelezo womsebenzi we-CP uphakathi kuka-8%-97%, i-EVCC ikhipha isignali yezinga eliphezulu le-A+ ku-BMS ukuze iyivuse. Ngemuva kwalokho, i-EVCC ithumela isicelo sokushaja i-AC ku-BMS.
7) Uma i-BMS ivumela ukushaja kwe-AC, ithumela isiqinisekiso sokushaja kwe-AC ku-EVCC, iqalise inqubo yokushaja ye-AC.
8) Uma i-BMS ingavumeli ukushaja kwe-AC, ibala ukuthi isikhathi esithathiwe ukuthumela isicelo sokushaja kwe-AC ku-BMS sidlula imizuzwana engama-20. Uma singadluli imizuzwana engama-20, sithumela kabusha isicelo sokushaja kwe-AC ku-BMS. Uma sidlula imizuzwana engama-20, inqubo yokushaja ye-AC iyaphela.
9) Uma umjikelezo womsebenzi we-CP ungewona u-5% noma u-8%-97%, ubala ukuthi isikhathi esithathiwe ukuthola umjikelezo womsebenzi we-CP sidlula imizuzwana engu-20. Uma ungadluli imizuzwana engu-20, ubuyela esinyathelweni sokutholwa kwenkampani ye-CP ukuze kucutshungulwe. Uma udlula imizuzwana engu-20, inqubo yokushaja iyaphela.
Inqubo yokuxhawulana kwe-PLC esinyathelweni sesi-5 ihlanganisa inqubo ye-SLAC, inqubo ye-SDP, kanye nokusungulwa koxhumano lwe-TCP.
Inqubo yokushaja imi kanje:
a. I-EVCC kanye ne-SECC ziqala ukushintshana kwemiyalezo ye-V2G. Bese kuthi i-SECC, ngokusekelwe kumyalezo wesicelo se-EVCC ngesikhathi sesigaba sokuxhawulana se-App Protocol esisekelwayo kanyeiziteshi zokushaja ze-EVisimo, sinquma ukuthi kufanele kusetshenziswe iphrothokholi yokushaja ye-DIN70121 noma ye-ISO15118. Ngaphezu kwalokho, ngesikhathi sesigaba sokuxhawulana se-App Protocol esisekelwayo, i-EVCC ithumela kuqala amaphrothokholi ayo asekelwayo ku-SECC. Njengoba ama-SECC ahlukene ngaphakathi kwe-iziteshi zokushaja izimoto zikagesiisekela amaphrothokholi okushaja ahlukene (amanye asekela i-DIN70121 kanye ne-ISO15118, kanti amanye asekela eyodwa kuphela), uma i-SECC isekela zombili, izokhetha iphrothokholi ebaluleke kakhulu esekelwa yi-EVCC. Uma i-SECC isekela iphrothokholi eyodwa kuphela, ingakhetha kuphela iphrothokholi ehambisanayo ngesikhathi senqubo yokushaja.
b. Uma i-SECC ikhetha iphrothokholi ye-DIN70121,isiteshi sokushaja imoto kagesikanyeimoto kagesiizoqala ukushaja i-DC.
c. Uma i-SECC ikhetha i-ISO 1511… 5.1.1.8 Protocol, futhi umaI-V2GUkushintshisana kwemiyalezo phakathi kwe-EVCC ne-SECC kufinyelela esigabeni se-ServiceDiscovery, i-SECC izokwazisa i-EVCC ngendlela yayo yokukhokha, indlela yokudlulisa amandla, i-ID yesevisi, kanye nohlobo lwesevisi;
d. Ngemva kwalokho, lapho ukushintshana kwemiyalezo ye-V2G phakathi kwe-EVCC ne-SECC kufinyelela esigabeni se-PaymentServiceSelection, futhi i-EVCC ikhetha i-External Payment njengendlela yokukhokha, i-EVCC ne-SECC zizongena kwimodi yokuqinisekisa yangaphandle ye-EIM; uma i-EVCC ikhetha i-Contract Payment njengendlela yokukhokha, i-EVCC ne-SECC zizongena kwimodi yokuqinisekisa ye-PNC plug-and-charge;
e. Uma i-EVCC kanye ne-SECC zingena kwimodi yokuqinisekisa yangaphandle futhi zisebenzisana nesigaba se-ChargeParameterDiscovery, uma indlela yokudlulisa amandla i-PEVRequestedEnergyTransfer eceliwe yi-EVCC iyi-AC, zizokwenza isethi yomlayezo we-AC Charging EIM, okungukuthi, ukushaja kwe-EIM AC; uma indlela yokudlulisa amandla i-PEVRequestedEnergyTransfer eceliwe yi-EVCC iyi-DC, zizokwenza i-DC… Ukushaja isethi yomlayezo we-EIM, okungukuthi, ukushaja kwe-EIM DC;
f. Uma i-EVCC kanye ne-SECC zingena kwimodi yokuqinisekisa i-plug-and-charge, futhi zixhumana nesigaba se-ChargeParameterDiscovery, uma indlela yokudlulisa amandla eceliwe yi-EVCC (PEVRequestedEnergyTransfer) iyi-AC, zizokwenza isethi yomlayezo we-AC Charging PNC, okungukuthi, ukushaja kwe-PNC AC; uma indlela yokudlulisa amandla eceliwe yi-EVCC (PEVRequestedEnergyTransfer) iyi-DC, zizokwenza isethi yomlayezo we-DC Charging PNC, okungukuthi, ukushaja kwe-PNC DC.
Inqubo yokushaja i-AC esinyathelweni sesi-7 imi kanje:
a. I-EVCC ithumela imiyalezo yomkhawulo wamanje wokushaja i-AC kanye nemiyalezo yesicelo sokuqala ukushaja ku-BMS ngokujikeleza. Uma i-BMS iphendula ngomlayezo othi “qala ukushaja kuvunyelwe”, i-EVCC kanye ne-BMS zingena esigabeni somjikelezo wokushaja.
b. Ngesikhathi sesigaba somjikelezo wokushaja, i-EVCC ithumela imiyalezo yomkhawulo wamanje wokushaja i-AC kanye nemiyalezo yesicelo sokumisa ukushaja ku-BMS ngokujikeleza.
c. Uma ibhethri selishajwe ngokugcwele noma isimo sokuma kokushaja sesihlangatsheziwe, i-BMS ithumela umlayezo wokuma kokushaja ku-EVCC, bese i-EVCC ingena enqubweni yokuvala ugesi ukuze iqede ukushaja.
