Uma i-architecture yemoto kagesi ithuthukiswa yaba ngu-800V, izindinganiso zemishini yayo enamandla kagesi aphezulu izokhushulwa ngokufanele, futhi isiguquli sizoshintshwa sisuke kumadivayisi endabuko e-IGBT siye kumadivayisi we-SiC we-MOSFET. Izindleko ze-inverter ngokwayo zingokwesibili kuphela ezingxenyeni zebhethri. Uma uthuthukela ku-SiC, izindleko zizokhuphukela kwelinye izinga.
Kodwa kuma-OEM, ukusetshenziswa kwe-silicon carbide ngokuvamile akubheki nje kuphela izindleko zamadivayisi wamandla, kodwa okubaluleke nakakhulu, izinguquko zezindleko zemoto yonke. Ngakho-ke, kubalulekile ukuthola ibhalansi phakathi kokonga kwezindleko okulethwe i-SiC nezindleko zayo eziphezulu.
Ngokuqondene ne-SiC, umuntu wokuqala ukuyizama kwakunguTesla.
Ngo-2018, u-Tesla washintsha amamojula e-IGBT ngamamojula e-silicon carbide okokuqala ku-Model 3. Ezingeni elifanayo lamandla, ubukhulu bephakheji yamamojula we-silicon carbide buncane kakhulu kunamamojula we-silicon, futhi ukulahlekelwa kokushintsha kuncishiswa ngo-75%. Ngaphezu kwalokho, uma kuguqulwa, ukusebenzisa amamojula e-SiC esikhundleni samamojula e-IGBT kungakhuphula ukusebenza kahle kohlelo cishe ngo-5%.
Ngokombono wezindleko, izindleko zokushintshwa zenyuke cishe ngamayuan ayi-1,500. Kodwa-ke, ngenxa yokuthuthukiswa kokusebenza kahle kwemoto, umthamo webhethri ofakiwe wehlisiwe, konga izindleko ohlangothini lwebhethri.
Lokhu kungathathwa njengokugembula okukhulu kukaTesla. Umthamo wayo omkhulu wemakethe unciphisa izindleko. U-Tesla uphinde wathembela kulokhu kubheja okukhulu ukuze abambe ubuchwepheshe nemakethe yezinhlelo zebhethri ze-400V.
Mayelana ne-800V, i-Porsche ihole ekuhlomiseni imoto yezemidlalo ye-Taycan esebenza ngogesi wonke ngohlelo lwe-800V ngo-2019, yaqala umjaho wezikhali we-800V high-voltage architecture yezimoto zikagesi.
Kukhona okuthile “okungalungile” mayelana nokuhlaziya izindleko ngombono we-Porsche. Phela igxile empumelelweni yemoto ewubukhazikhazi futhi igxile emalini yohlobo oluphambili.
Kodwa mayelana nokuthuthukiswa kobuchwepheshe kanye nokusetshenziswa, lena iphrojekthi enkulu ethinta wonke umzimba. Isibonelo, ngaphansi kokushajwa kwe-high-voltage engu-800V, i-voltage yephakethe lebhethri kufanele ikhuphuke ngokuqhathaniswa ibe ngu-800V, ngaphandle kwalokho izoshiswa ngenxa yamanje yokushaja okukhulu. Ngaphezu kwalokho, akubandakanyi nje kuphela uhlelo lokushaja, kodwa futhi uhlelo lwebhethri, uhlelo lokushayela kagesi, izesekeli eziphezulu ze-voltage kanye nesistimu ye-wiring harness, ethinta ukuqala, ukushayela, ukusetshenziswa kwe-air conditioning yemoto, njll.
Uma ufuna ukwazi okwengeziwe ngalokhu, sicela ukhululeke ukuxhumana nathi.
