Amma ga OEMs, aikace-aikacen silicon carbide gabaɗaya baya la'akari da farashin na'urorin wutar lantarki kawai, amma mafi mahimmanci, canjin farashin duk abin hawa.Sabili da haka, yana da mahimmanci don nemo ma'auni tsakanin ajiyar kuɗin da SiC ta kawo da kuma babban farashi.
Dangane da batun SiC, mutumin da ya fara gwada shi shine Tesla.
A cikin 2018, Tesla ya maye gurbin na'urorin IGBT tare da na'urori na silicon carbide a karo na farko a cikin Model 3. A daidai wannan matakin ƙarfin, girman kunshin siliki na siliki ya fi ƙanƙanta fiye da na siliki, kuma an rage asarar hasara ta 75%.Bugu da ƙari, idan an canza, ta yin amfani da na'urori na SiC maimakon IGBT na iya haɓaka ingantaccen tsarin da kusan 5%.
Ta fuskar farashi, farashin canji ya karu da kusan yuan 1,500.Koyaya, saboda haɓaka ingancin abin hawa, ƙarfin baturin da aka shigar ya ragu, yana adana farashi a gefen baturi.
Ana iya ɗaukar wannan azaman babban caca ga Tesla.Babban girman kasuwar sa yana daidaita farashin.Tesla kuma ya dogara da wannan babban fare don kwace fasaha da kasuwa na tsarin batir 400V.
Dangane da 800V, Porsche ya jagoranci gaba wajen ba wa motar wasan motsa jiki ta Taycan mai amfani da wutar lantarki da tsarin 800V a cikin 2019, inda ya kafa tseren makamai don gine-ginen 800V mai ƙarfin lantarki na motocin lantarki.
