40kW SiC DC EV Utu Whai Hua teitei

He tino kaha te pūmanawa o te waeine utu tere SiC i te mea kei te piki haere te hiahia mō te utu tere ngaohiko teitei. Whai muri i te whakaaturanga tuatahi o te ao a Porsche mō te tauira tūāpapa hiko-teitei 800V Taycan i te marama o Hepetema 2019, kua tukuna e ngā kamupene EV nunui ngā tauira utu tere hiko-teitei 800V, pērā i a Hyundai IONIQ, Lotus Eletre, BYD Dolphin, Audi RS e-tron GT, me ētahi atu. Ka tukuna katoatia, ka hangaia rānei i roto i ēnei tau e rua. Kei te rongonui haere te utu tere 800V i te mākete; E matapaetia ana e CITIC Securities, tae noa ki te tau 2025, ka eke te maha o ngā tauira utu tere ngaohiko-tiketike ki te 5.18 miriona, ā, ka piki ake te tere urunga mai i te nāianei neke atu i te 10% ki te 34%. Ka waiho tēnei hei tino kaha mō te tipu o te mākete utu tere ngaohiko-tiketike, ā, e matapaetia ana ka whai hua tika ngā kamupene o runga ake i tēnei. E ai ki ngā kōrero a te marea, ko te waeine utu te wāhanga matua o te puranga utu, e 50% te utu katoa o te puranga utu; i roto i ēnei, ko te taputapu hiko haurua-ira e 30% te utu o te waeine utu, arā, ko te waeine hiko haurua-ira e 15% te utu o te puranga utu, ka waiho hei mekameka painga matua i roto i te tukanga whanaketanga o te mākete puranga utu. I tēnei wā, ko ngā taputapu hiko e whakamahia ana i roto i ngā puranga utu ko ngā IGBT me ngā MOSFET, ā, he hua Si-e rua ēnei, ā, nā te whanaketanga o ngā puranga utu ki te utu tere DC kua piki ake ngā whakaritenga mō ngā taputapu hiko. Kia tere ai te utu waka me te tere o te whakakī hinu i te teihana penehīni, kei te rapu pukumahi ngā kaihanga waka i ngā rauemi hei whakapai ake i te pai o te mahi, ā, ko te silicon carbide te kaiārahi i tēnei wā. He pai ngā painga o te silicon carbide, arā, te ātete ki te pāmahana teitei, te ātete ki te pēhanga teitei, te kaha teitei, me ētahi atu, ka taea te whakapai ake i te pai o te hurihanga pūngao me te whakaiti i te rahinga o te hua. Ko te nuinga o ngā waka hiko e whakamahi ana i ngā kaupapa utu AC kei runga i te papa, ā, me roa te wā ki te utu katoa. Ko te whakamahi i te mana teitei (pēnei i te 30kW me runga ake) hei whakatutuki i te utu tere o ngā waka hiko kua noho hei huarahi whakatakotoranga nui e whai ake nei mō ngā pou utu. Ahakoa ngā painga o ngā puranga utu hiko teitei, he maha ngā wero e pā mai ana, pērā i: te hiahia kia whakatinanahia ngā mahi whakawhiti auau teitei teitei, me te wera e puta mai ana i ngā ngaronga huringa. Heoi, ko ngā hua SiC MOSFET me ngā diode he āhuatanga o te ātete ngaohiko teitei, te ātete pāmahana teitei, me te auau whakawhiti tere, ka taea te whakamahi pai i roto i ngā kōwae puranga utu. Ki te whakatauritea ki ngā taputapu hiko-silicon tuku iho, ka taea e ngā kōwae silicon carbide te whakanui ake i te mana putanga o ngā puranga utu tata ki te 30%, me te whakaiti i ngā ngaronga tae atu ki te 50%. I taua wā anō, ka taea hoki e ngā taputapu silicon carbide te whakarei ake i te pumau o ngā puranga utu. Mō ngā puranga utu, ko te utu tonu tētahi o ngā mea nui e aukati ana i te whanaketanga, nō reira he mea tino nui te kaha o ngā puranga utu, ā, ko ngā taputapu SiC te mea nui ki te whakatutuki i te kaha teitei o te kaha. Hei taputapu ngaohiko teitei, tere teitei, me te au nui, ka whakangawarihia e ngā taputapu silicon carbide te hanganga ara iahiko o te waeine utu puranga DC, ka whakanui ake i te taumata kaha o te waeine, ā, ka tino whakanui ake i te kaha o te kaha, ka whakatakoto huarahi mō te whakaiti i te utu pūnaha o te puranga utu. Mai i te tirohanga o te utu mō te wā roa me te whai huatanga o te whakamahinga, ka puta mai i ngā puranga utu hiko kaha-tiketike e whakamahi ana i ngā taputapu SiC he maha ngā whai wāhitanga mākete. E ai ki ngā raraunga a CITIC Securities, i tēnei wā, ko te tere urunga o ngā taputapu silicon carbide ki roto i ngā puranga utu waka hiko hou he tata ki te 10% noa iho, ā, he whānui anō hoki te wāhi e toe ana mō ngā puranga utu mana-teitei. Hei kaiwhakarato matua i roto i te umanga utu DC, kua whakawhanakehia e MIDA Power, kua tukuna hoki te hua waeine utu me te kaha teitei rawa atu, ko te waeine utu taumata tiaki IP65 tuatahi me te hangarau paipa hau motuhake. Me te rōpū R&D kaha me te kaupapa aro ki te mākete, kua whakapau kaha a MIDA Power, ā, kua angitu te whakawhanake i te waeine utu SiC 40kW. Me te kaha teitei whakamiharo neke atu i te 97% me te whānuitanga ngaohiko whakauru tino whānui mai i te 150VDC ki te 1000VDC, ka tutuki i te waeine utu SiC 40kW te nuinga o ngā paerewa whakauru o te ao, me te penapena hiko nui. I te tere o te tipu o te maha o ngā puranga utu, e whakaponohia ana ka nui haere te whakamahinga o ngā MOSFET SiC, me te waeine utu SiC MIDA Power 40kW i roto i ngā puranga utu e hiahia ana ki te kaha teitei ake i te heke mai.
