Ingaphakathi lemoto lenziwe ngezinto eziningi, ikakhulukazi ngemuva kokufakwa kukagesi.Inhloso yesikhulumi sikagesi ukufanisa izidingo zamandla ezingxenye ezahlukene.Ezinye izingxenye zidinga i-voltage ephansi uma kuqhathaniswa, efana ne-electronics yomzimba, okokusebenza kokuzijabulisa, izilawuli, njll. (ngokuvamile ukunikezwa kwamandla kagesi weplathifomu engu-12V), kanti ezinye zidinga amandla alinganiselwe.i-voltage ephezulu, njengamasistimu ebhethri, amasistimu okushayela amandla kagesi aphezulu, amasistimu wokushaja, njll. (400V/800V), ngakho-ke kukhona inkundla yamandla kagesi aphezulu kanye neplathifomu yamandla kagesi aphansi.
Bese ucacisa ubudlelwano phakathi kwe-800V ne-super fast charge: Manje imoto yomgibeli kagesi ehlanzekile ngokuvamile imayelana nesistimu yebhethri engu-400V, i-motor ehambisanayo, izesekeli, ikhebula le-voltage ephezulu nayo isezingeni elifanayo le-voltage, uma i-voltage yesistimu inyuswa, kusho ukuthi ngaphansi kwesidingo esifanayo samandla, i-current ingancishiswa ngesigamu, lonke ukulahlekelwa kwesistimu kuba kuncane, ukushisa kuncishisiwe, kodwa futhi okunye okungasindi, ukusebenza kwemoto kusiza kakhulu.
Eqinisweni, ukushaja okusheshayo akuhlobene ngokuqondile ne-800V, ikakhulukazi ngenxa yokuthi izinga lokushaja lebhethri liphakeme, okuvumela ukushaja kwamandla amakhulu, okuyinto ngokwayo engahlangene ne-800V, njenge-platform ye-Tesla 400V, kodwa ingafinyelela ngokushesha okukhulu. ukushaja ngendlela yamanje ephezulu.Kodwa i-800V iwukufeza ukushaja kwamandla aphezulu inikeza isisekelo esihle, ngoba okufanayo ukuze kufinyelele amandla okushaja angu-360kW, ithiyori ye-800V idinga kuphela i-450A yamanje, uma iyi-400V, idinga i-900A yamanje, i-900A ezimweni zamanje zobuchwepheshe zezimoto zabagibeli cishe akunakwenzeka.Ngakho-ke, kunengqondo kakhudlwana ukuxhumanisa i-800V kanye nokushaja okusheshayo okukhulu ndawonye, okubizwa ngokuthi iplathifomu yobuchwepheshe yokushaja esheshayo engu-800V.
Njengamanje, kunezinhlobo ezintathu zehigh-voltageizakhiwo zesistimu okulindeleke ukuthi zifinyelele ekushajelweni okusheshayo kwamandla aphezulu, futhi isistimu egcwele yamandla kagesi aphezulu kulindeleke ukuthi ibe inkambiso:
(1) Isistimu egcwele yamandla kagesi aphezulu, okungukuthi, ibhethri lamandla angu-800V +800V motor, isilawuli sikagesi +800V OBC, DC/DC, PDU+800V air conditioning, PTC.
Izinzuzo: Izinga eliphezulu lokuguqulwa kwamandla, isibonelo, izinga lokuguqulwa kwamandla kagesi wesistimu yokushayela ngu-90%, izinga lokuguqulwa kwamandla ka-DC/DC lingama-92%, uma lonke uhlelo lunamandla kagesi, akudingekile ukucindezela ngokusebenzisa I-DC/DC, izinga lokuguqulwa kwamandla esistimu ngu-90%×92%=82.8%.
Ubuthakathaka: Isakhiwo asigcini nje ngokuba nezidingo eziphezulu kusistimu yebhethri, isilawuli sikagesi, i-OBC, i-DC/DC amadivayisi kagesi adinga ukushintshwa yi-Si-based IGBT SiC MOSFET, i-motor, compressor, i-PTC, njll. idinga ukuthuthukisa ukusebenza kwe-voltage , ukukhuphuka kwezindleko zesikhathi esifushane zokuphela kwemoto kuphakeme, kodwa ngokuhamba kwesikhathi, ngemva kokuba uchungechunge lwezimboni seluvuthiwe kanye nomphumela wesilinganiso.Umthamo wezingxenye ezithile uyancipha, ukusebenza kahle kwamandla kuyathuthukiswa, futhi izindleko zemoto zizokwehla.
(2) Ingxenye yei-voltage ephezulu, okungukuthi, ibhethri engu-800V +400V motor, isilawuli sikagesi +400V OBC, DC/DC, PDU +400V air conditioning, PTC.
Izinzuzo: ngokuyisisekelo sebenzisa isakhiwo esikhona, thuthukisa kuphela ibhethri lamandla, izindleko zokuguqulwa kokuphela kwemoto zincane, futhi kukhona ukusebenziseka okukhulu esikhathini esifushane.
Ukungalungi: Ukwehla kwe-DC/DC kusetshenziswa ezindaweni eziningi, futhi ukulahlekelwa kwamandla kukhulu.
(3) Yonke i-low-voltage architecture, okungukuthi, ibhethri engu-400V (ishaja i-800V ngochungechunge, ikhipha i-400V ngokuhambisana) +400V motor, isilawuli sikagesi +400V OBC, DC/DC, PDU +400V air conditioning, PTC.
Izinzuzo: Ukuguqulwa kokuphela kwemoto kuncane, ibhethri idinga kuphela ukuguqulwa kwe-BMS.
Ukungalungi: ukukhuphuka kochungechunge, ukwanda kwezindleko zebhethri, sebenzisa ibhethri lamandla langempela, ukuthuthukiswa kokushaja kahle kunqunyelwe.
