Izixhobo ze-EV
Njengoko ishishini lezothutho lehlabathi lisiya kwi-low-carbon kunye nokufakelwa kombane, imfuno yamandla okutshaja aphezulu kakhulu kwizixhobo ezinkulu ezifana nezithuthi zothutho ezinzima, iinqanawa, iinqwelomoya, kunye noomatshini bobunjineli iya isanda. Inkqubo yokutshaja yeMegawatt (MCS), enamandla okutshaja afikelela kwi-3.75 MW, iye yaba yeyona nto iphambili kwitekhnoloji eqhuba ukufakwa kombane kwiindawo ezikhankanyiweyo apha ngasentla. I-MCS ayinakukhawulezisa kuphela ixesha lokutshaja kakhulu, kodwa ikwahlangabezana neemfuno zeemeko zokusebenza ezinzima kunye neziphindaphindayo, eziluncedo olubalulekileyo ekufezekiseni utshintsho lwamandla aluhlaza.
Umthamo webhetri yezithuthi ezinkulu udla ngokuphindwe kalishumi kunoweemoto zabakhweli, kwaye iindlela zokutshaja zemveli kunzima ukuhlangabezana nokuhlaziywa kwamandla okukhawulezileyo kwezixhobo ezinkulu zoomatshini. Ke ngoko, xa kuthelekiswa nokutshaja kweDC okuqhelekileyo kweCCS yaseYurophu, imfuneko yamandla ayo okutshaja kufuneka inyuswe ngamaxesha ali-10-15 (jonga uMfanekiso 1). I-MCS okwangoku inokutshaja iibhetri zezithuthi ezinzima ukuya kwi-80% SOC kwimizuzu engama-45 ngokunyusa i-voltage yokutshaja kunye nombane, ofuna amandla aphezulu angama-3.75 MW kwaye ikwahambelana nexesha lokuphumla elisemthethweni lokuqhuba umgama omde.
Xa kuthelekiswa nemigangatho ye-GB/T, i-CHAdeMO, i-CCS, kunye ne-NACS, i-MCS ifikelela ekunciphiseni kwexesha lokutshaja ngama-4.2 ukuya kwi-15 amaxesha. Kwinqanaba lobugcisa, i-MCS ivela kwi-CCS, kodwa kukho umahluko omkhulu phakathi kwezi zimbini kwiinkalo ezithile:
Ujongano lokutshaja kunye nonxibelelwano oluphantsi
I-interface ye-MCS echazwe yi-IEC TS 63379 iyakwazi ukudlulisa ukuya kuthi ga kwi-3000A current kwaye ixhase i-voltage ye-1250V, kunye nokupholisa ulwelo okunyanzelekileyo okufunekayo kwiimeko zamandla aphezulu.
Umgangatho wonxibelelwano oluphantsi lwe-MCS yi-IEC 61851-23-3 (kulindeleke ukuba ikhutshwe ngo-2026). Ukulawula iphini yokulinganisa kwi-MCS kubizwa ngokuba yi-Charge Enable (CE), esebenzisa i-voltage ye-5V DC kwaye akukho PWM. Njengephini ye-PP kwi-CCS, i-MCS isebenzisa i-5V DC ukufumanisa ukufakwa (ID), enokubonelela ngombane we-12/24V kwizixhobo zombane ezincedisayo.
1. Unxibelelwano oluphezulu: 10BASE-T1S Unxibelelwano oluneendawo ezininzi
Unxibelelwano oluphezulu lusekelwe kwi-ISO 15118-20, kwaye isilungiso sayo 1 (ISO 15118-20 Amd-1) sazisa ii-ID zenkonzo ezongezelelweyo ze-MCS. Ulwakhiwo lonxibelelwano lufana ne-CCS, olusebenzisa i-TLS, i-TCP/IP, i-Ethernet, kodwa umaleko obonakalayo wamkela i-10BASE-T1S echazwe kwi-ISO 15118-10. I-10BASE-T1S yi-Ethernet ephindwe kabini enye, ene-bandwidth ye-10Mbps half duplex, kwaye yamkela i-differential Manchester coding (DME) ngokusekelwe kwi-IEEE 802.3cg specification. Unxibelelwano oluphezulu lwe-MCS aludingi nxibelelwano lomphathi wentambo yamandla (PLC), kwaye aludingi nenkqubo ye-SLAC (signal level attenuation characteristic) yokufumanisa imeko yonxibelelwano.
2. Indlela yonxibelelwano ye-PLCA
Ngokungafaniyo nonxibelelwano oluvela kwindawo ukuya kwindawo lwe-Ethernet eqhelekileyo, i-10BASE-T1 ixhasa unxibelelwano oluvela kwiindawo ezininzi kunye nendlela yokuthintela ukungqubana kwe-Physical Layer Collision Avoidance (PLCA). Isiseko sayo se-EVSE sisebenza njengomququzeleli, sinikezela nge-node ID 0 kunye ne-EV electric vehicle ID 1 (Drop Node 1). Ngokwe-ISO 15118-10, ibhasi yonxibelelwano inokuxhasa ukuya kuthi ga kwii-node ezi-6 ezongezelelweyo (Drop Nodes), ezifana nokudlulisa idatha yesenzi, umbane, ubushushu, kunye nolunye ulwazi lweplagi kunye nesokethi. I-PLCA inokuphucula ngakumbi inkqubo yonxibelelwano, iphucule ukusebenza kakuhle kokudluliselwa kwedatha phakathi kwee-node ezininzi, kwaye iqinisekise ukuhambelana kunye nokhuseleko lolwazi kwikhonkco ngalinye lenkqubo yokutshaja.
Uphuhliso kunye novavanyo lwe-MCS
Nangona ukubekwa emgangathweni kwe-MCS kungekagqitywa, uphuhliso lweenkqubo zokutshaja zabavelisi bezithuthi kunye neziseko zophuhliso sele luqalile. Ukulinganisa nokuvavanya kwinqanaba lokuqala kunokunceda ukuthintela iimpazamo zoyilo, ukunciphisa ixesha lokulungisa, kunye neendleko eziphantsi.
Isisombululo sovavanyo lokulinganisa i-MCS esakhiwe yiVector siquka uvavanyo lokusebenza kunye nophuhliso lonxibelelwano lwenqanaba le-EVCC/SEC, uvavanyo lokuvumelana kunye nokusebenzisana, uvavanyo lwamandla okusebenza kwenqanaba le-megawatt, kunye nokuqokelelwa kwedatha kunye nohlalutyo lwe-EV/EVSE yesithuthi sokwenyani kunye nenqwaba, ukuhlangabezana neemeko zokusetyenziswa kweenjineli kwiinkalo ezahlukeneyo (Umfanekiso 4).
Iqonga lesoftware yohlalutyo lwe-EV/EVSE, ukulinganisa, kunye nokuvavanya elihlangabezana neenkqubo ze-MCS/CCS/OCPP/GBT/CHAdeMO kwiindawo ezahlukeneyo.
Yimodyuli yonxibelelwano ekhuselekileyo efakwe kwisoftware, exhasa ukubethela kwe-TLS 1.2/1.3, iitemplate zesatifikethi sokhuseleko se-PnC, kunye nokuqinisekiswa kwe-Subject trusted root interconnect authentication.
Ibhodi yokutshaja ekrelekrele yesizukulwana esitsha ibonelela ngokulinganisa i-CCS (PLC)/MCS yesikhokelo sesekethe yezixhobo, kwaye ikwaxhasa ukulinganisa iimpazamo zemaleko ebonakalayo.
Ikhadi le-interface yonxibelelwano lixhasa i-10BASE-T1S, nto leyo evumela unxibelelwano oluphezulu lwe-MCS kunye nonxibelelwano lwe-MultiDrop multi-point.
Ibhentshi yovavanyo enegunya lokutshaja eliphezulu le-3.84MW kunye ne-1500V inokubonelelwa, equka imodyuli yokulawula ephambili ye-180kW kunye neerakhi zamandla ezongezelelweyo zokwandiswa.
Nika ithala leencwadi lovavanyo oluqhelekileyo lwe-ISO 15118 kunye nendawo yekhowudi yomthombo (vTESTstudio), evumela abavavanyi ukuba basebenzise ngokukhawuleza ulandelelwano lovavanyo oluqhelekileyo ngaphaya komgangatho.
Njengeteknoloji ephambili yokufakelwa kombane kwiindlela ezinzima zokuthutha, ukubekwa emgangathweni, ukuthembeka, kunye nokuguquguquka kwe-MCS kuya kuchaphazela ngqo inkqubo yophuhliso lweli shishini. Kwixesha elizayo, ngokuphuculwa okuqhubekayo kwemigangatho kunye nokuphuculwa kwezixhobo zokuvavanya, i-MCS kulindeleke ukuba isetyenziswe kakhulu kwiinkalo zezothutho, amazibuko, iinqwelomoya, kunye noomatshini bobunjineli.
Ngokusebenzisa izixhobo ezifanelekileyo zophuhliso, ukulinganisa, kunye nokuvavanya, ubunzima kunye neengozi ezinokubakho zenkqubo zinokujongwa. Inkqubo enikezelwa yiVector inokuguquguquka okuphezulu kunye nokukhula, kubandakanya uvavanyo lokusebenza ngamandla aphezulu okutshaja achazwe yiMCS, ngelixa isixhobo sezixhobo sigubungela ngaphandle komthungo eminye imigangatho yokutshaja, sigubungela ngcono iimfuno zeeprojekthi ezahlukeneyo. IVector ikwathatha inxaxheba kwiikomiti ezifanelekileyo zokulinganisa kwaye ilungisa ngokukhawuleza izisombululo ukuze zivumelane nenkqubo yamva nje yokulinganisa yeMCS.
