Ki te whakapai ake te hanganga o te waka hiko ki te 800V, ka whakapiki ake ngā paerewa o ana taputapu ngaohiko-tiketike, ā, ka whakakapia hoki te inverter mai i ngā taputapu IGBT tuku iho ki ngā taputapu MOSFET rauemi SiC. Ko te utu o te inverter tonu te tuarua o ngā wāhanga pākahiko. Ki te whakapai ake koe ki te SiC, ka piki ake te utu ki tētahi atu taumata.
Engari mō ngā OEM, ko te whakamahinga o te silicon carbide ehara i te mea ko te utu o ngā taputapu hiko anake te mea nui, engari ko te mea nui ake, ko ngā huringa utu o te waka katoa. Nō reira, he mea nui kia kitea he taurite i waenga i ngā penapena utu e kawea mai ana e te SiC me tōna utu nui.
Mō SiC, ko Tesla te tangata tuatahi i whakamātau.
I te tau 2018, i whakakapia e Tesla ngā kōwae IGBT ki ngā kōwae silicon carbide mō te wā tuatahi i roto i te Tauira 3. I te taumata mana kotahi, he iti ake te rahi o te kete o ngā kōwae silicon carbide i ērā o ngā kōwae silicon, ā, ka whakaitihia ngā mate whakawhiti mā te 75%. Hei tāpiri, ki te hurihia, mā te whakamahi i ngā kōwae SiC hei utu mō ngā kōwae IGBT ka taea te whakanui ake i te pai o te pūnaha mā te 5%.
Mai i te tirohanga utu, kua piki ake te utu whakakapinga mā te tata ki te 1,500 yuan. Heoi, nā te whakapainga o te whai huatanga o te waka, kua whakaitihia te kaha o te pākahiko kua tāutahia, ā, kua penapenahia ngā utu i te taha pākahiko.
He petipeti nui tēnei mā Tesla. Nā te nui o te mākete ka ea te utu. I whakawhirinaki anō a Tesla ki tēnei petipeti nui hei hopu i te hangarau me te mākete o ngā pūnaha pākahiko 400V.
Mō te 800V, i ārahi a Porsche i te whakaurunga o te pūnaha 800V mō te motuka hākinakina hiko katoa a Taycan i te tau 2019, ā, i tīmata ai tētahi whakataetae patu mō te hoahoa ngaohiko-tiketike 800V o ngā waka hiko.
He mea "kāore i te tika" te tātari i ngā utu mai i te tirohanga a Porsche. Heoi anō, e aro ana ki te pānga o te motuka papai, ā, e aro ana ki te kounga o te waitohu.
Engari mō te whanaketanga me te whakamahinga o te hangarau, he kaupapa nui tēnei e pā ana ki te tinana katoa. Hei tauira, i raro i te utunga hiko teitei 800V, me whakanui ake te hiko o te pākahiko ki te 800V, ki te kore ka wera nā te nui o te ia utu. Hei tāpiri, ehara i te mea ko te pūnaha utu anake e pā ana, engari ko te pūnaha pākahiko, te pūnaha taraiwa hiko, ngā taputapu hiko teitei me te pūnaha taura waea, e pā ana ki te tīmatanga, te taraiwa, te whakamahinga hauhautanga o te waka, me ētahi atu.
