Uma ukwakheka kwezimoto zikagesi kuthuthukiswa kube yi-800V, amazinga amadivayisi ayo ane-voltage ephezulu azokhushulwa ngokufanele, futhi i-inverter izothathelwa indawo kusuka kumadivayisi e-IGBT endabuko kuya kumadivayisi e-MOSFET e-SiC. Izindleko ze-inverter ngokwayo zilandela izingxenye zebhethri kuphela. Uma uthuthukela ku-SiC, izindleko zizokhuphukela kwelinye izinga.
Kodwa kuma-OEM, ukusetshenziswa kwe-silicon carbide ngokuvamile akubheki nje kuphela izindleko zamadivayisi kagesi, kodwa okubaluleke kakhulu, izinguquko zezindleko zemoto yonke. Ngakho-ke, kubalulekile ukuthola ibhalansi phakathi kokonga izindleko okulethwe yi-SiC kanye nezindleko zayo eziphakeme.
Ngokuphathelene ne-SiC, umuntu wokuqala ukuyizama kwakunguTesla.
Ngo-2018, iTesla yashintsha amamojula e-IGBT ngamamojula e-silicon carbide okokuqala kuModeli 3. Ezingeni elifanayo lamandla, usayizi wephakheji yamamojula e-silicon carbide mncane kakhulu kunowamamojula e-silicon, futhi ukulahlekelwa kokushintshana kuncishiswa ngo-75%. Ngaphezu kwalokho, uma kuguqulwa, ukusebenzisa amamojula e-SiC esikhundleni samamojula e-IGBT kungandisa ukusebenza kahle kohlelo cishe ngo-5%.
Uma sibheka izindleko, izindleko zokufaka esikhundleni zikhuphuke cishe ngama-yuan ayi-1,500. Kodwa-ke, ngenxa yokuthuthuka kokusebenza kahle kwemoto, umthamo webhethri elifakiwe unciphile, okusindisa izindleko ohlangothini lwebhethri.
Lokhu kungabhekwa njengokubheja okukhulu kweTesla. Umthamo wayo omkhulu wemakethe unciphisa izindleko. I-Tesla iphinde yathembela kulokhu kubheja okukhulu ukuze ithathe ubuchwepheshe kanye nemakethe yezinhlelo zamabhethri angu-400V.
Ngokuphathelene ne-800V, iPorsche yahola ekuhlomiseni imoto yezemidlalo iTaycan esebenza ngogesi kuphela ngohlelo lwe-800V ngo-2019, yaqala umjaho wezikhali wokwakhiwa kwezimoto zikagesi ze-800V ezinamandla aphezulu.
Kukhona okuthile "okungafanele" ngokuhlaziya izindleko ngokombono wePorsche. Phela, igxile emphumeleni wezimoto zikanokusho futhi igxile ekukhazimuleni komkhiqizo.
Kodwa maqondana nokuthuthukiswa kobuchwepheshe kanye nokusetshenziswa, lokhu kuyiphrojekthi enkulu ethinta umzimba wonke. Isibonelo, ngaphansi kokushaja kwe-voltage ephezulu engu-800V, i-voltage yebhethri kumele ikhuliswe kancane ibe ngu-800V, ngaphandle kwalokho izoshiswa ngenxa yamandla amakhulu okushaja. Ngaphezu kwalokho, akubandakanyi nje kuphela uhlelo lokushaja, kodwa futhi nohlelo lwebhethri, uhlelo lokushayela ngogesi, izesekeli ze-voltage ephezulu kanye nohlelo lwe-wiring harness, okuthinta ukuqala, ukushayela, ukusetshenziswa kwe-air conditioning yemoto, njll.
Uma ufuna ukwazi okwengeziwe ngalokhu, sicela ukhululeke ukuxhumana nathi.
