Ingaphakathi lemoto lenziwe ngamacandelo amaninzi, ngakumbi emva kokufakelwa kombane. Injongo yeqonga lombane kukuhambelana neemfuno zamandla amacandelo ahlukeneyo. Amanye amalungu afuna amandla ombane aphantsi ngokwentelekiso, afana ne-electronics yomzimba, izixhobo zokuzonwabisa, abalawuli, njl.njl. (unikezelo lwamandla ombane oluqhelekileyo lweqonga le-12V), kwaye amanye afuna amandlaamandla ombane aphezulu, ezifana neenkqubo zebhetri, iinkqubo zokuqhuba umbane ophezulu, iinkqubo zokutshaja, njl. (400V / 800V), ngoko kukho iqonga eliphezulu lombane kunye neqonga eliphantsi lombane.
Emva koko ucacise ubudlelwane phakathi kwe-800V kunye nentlawulo ekhawulezayo: Ngoku imoto yomkhweli yombane esulungekileyo ihlala imalunga ne-400V inkqubo yebhetri, i-motor ehambelanayo, izixhobo, intambo yombane ephezulu ikwakwinqanaba lombane elifanayo, ukuba amandla ombane anyukile, oko kuthetha ukuba. phantsi kwemfuno efanayo yamandla, okwangoku kungancitshiswa ngesiqingatha, yonke ilahleko yenkqubo iba yincinci, ubushushu buyancipha, kodwa kwakhona bulula ngakumbi, ukusebenza kwesithuthi kunceda kakhulu.
Enyanisweni, ukutshaja ngokukhawuleza akuhambelani ngokuthe ngqo kwi-800V, ngakumbi ngenxa yokuba izinga lokutshaja kwebhetri liphezulu, livumela ukutshaja kwamandla amakhulu, nto leyo yona ngokwayo ayinanto yakwenza ne-800V, njengeqonga likaTesla le-400V, kodwa inokufezekisa ngokukhawuleza okukhulu. ukutshaja ngendlela yangoku ephezulu. Kodwa i-800V kukuphumeza ukutshaja kwamandla aphezulu kunika isiseko esihle, kuba okufanayo ukufikelela kwi-360kW amandla okutshaja, i-800V ithiyori ifuna kuphela i-450A yangoku, ukuba i-400V, idinga i-900A yangoku, i-900A kwiimeko zobugcisa zangoku kwiimoto zabahambi. phantse akunakwenzeka. Ngoko ke, kunengqiqo ngakumbi ukudibanisa i-800V kunye nentlawulo ekhawulezayo kunye, ebizwa ngokuba yi-800V iqonga lobuchwepheshe lokutshaja ngokukhawuleza.
Okwangoku, kukho iintlobo ezintathuamandla ombane aphezuluUyilo lwenkqubo ekulindeleke ukuba lufezekise intlawulo ephezulu yamandla, kunye nenkqubo epheleleyo yevoltage ephezulu kulindeleke ukuba ibe yeyona iphambili:
(1) Inkqubo epheleleyo yombane ophezulu, oko kukuthi, i-800V ibhetri yamandla + 800V motor, ulawulo lombane + 800V OBC, DC / DC, PDU + 800V air conditioning, PTC.
Izinto eziluncedo: Izinga lokuguqulwa kwamandla aphezulu, umzekelo, izinga lokuguqulwa kwamandla ombane wokuqhuba umbane ngu-90%, izinga lokuguqulwa kwamandla e-DC / DC yi-92%, ukuba yonke inkqubo iphezulu yombane, akuyimfuneko ukuxinzelela phantsi. I-DC / DC, izinga lokuguqulwa kwamandla enkqubo yi-90% × 92% = 82.8%.
Ubuthathaka: Ulwakhiwo alunazidingo eziphezulu kuphela kwinkqubo yebhetri, ulawulo lombane, i-OBC, DC/DC izixhobo zamandla kufuneka zitshintshwe yi-Si-based IGBT SiC MOSFET, motor, compressor, PTC, njl. , ukunyuswa kweendleko zemoto zexesha elifutshane kuphezulu, kodwa kwixesha elide, emva kokuba i-industrial chain chain ikhulile kwaye umphumo wesikali unawo. Umthamo wezinye iindawo uyancitshiswa, ukusebenza kakuhle kwamandla kuphuculwe, kwaye iindleko zesithuthi ziya kuwa.
(2) Inxalenye yeamandla ombane aphezulu, oko kukuthi, ibhetri ye-800V + 400V motor, ulawulo lombane + 400V OBC, DC / DC, PDU + 400V air conditioning, PTC.
Izinto eziluncedo: ngokusisiseko sebenzisa isakhiwo esele sikhona, phucula kuphela ibhetri yamandla, ixabiso lenguquko yokuphela kwemoto lincinci, kwaye kukho ukusebenziseka okukhulu kwixeshana elifutshane.
Ukungalungi: I-DC / DC i-step-down isetyenziswa kwiindawo ezininzi, kwaye ilahleko yamandla inkulu.
(3) Yonke i-architecture ye-low-voltage, oko kukuthi, ibhetri ye-400V (ukuhlawula i-800V kwi-series, ukukhupha i-400V ngokufana) + i-400V motor, ulawulo lombane + 400V OBC, DC / DC, PDU + 400V air conditioning, PTC.
Izinto eziluncedo: Ukutshintshwa kokuphela kwemoto kuncinci, ibhetri idinga kuphela ukuguqulwa kweBMS.
Izinto ezingeloncedo: ukonyuka kothotho, ukonyuka kweendleko zebhetri, sebenzisa ibhetri yamandla oqobo, ukuphuculwa kokutshaja ngokufanelekileyo kulinganiselwe.
