Toyota yiyemeje gutera indi ntera mugutezimbere ibinyabiziga bivangavanze n'amashanyarazi. Menya sisitemu nshya ikoresha Silicon Carbide mukubaka moderi igenzura amashanyarazi, hamwe n'amasezerano yo gukora neza.
Toyota yabaye imwe mubirango byashora imari cyane mugutezimbere ubundi buryo bwikoranabuhanga ryimodoka, hamwe na Denso, mubufatanye bumaze imyaka 34 yubahwa.
Nkibisubizo byubushakashatsi, Toyota ubu irerekana igisekuru gishya cyamashanyarazi (PCU) - aricyo kigo gikora muri izi modoka - ukoresheje kimwe mubikoresho bigoye kwisi: Silicon Carbide (SiC).
Binyuze mu gukoresha semiconductor ya Silicon Carbide (SiC) mu iyubakwa rya PCU - byangiza semiconductor gakondo ya silicon - Toyota ivuga ko bishoboka kuzamura ubwigenge bw’ibinyabiziga bivangavanze n’amashanyarazi hafi 10%.
Birashobora kuba akarusho, ariko twakagombye kumenya ko abayobora SiC bafite inshingano zo gutakaza ingufu za 1/10 gusa mugihe cyubu, ibyo bikaba bigabanya kugabanya ubunini bwibigize nka coil na capacator hafi 40%, byerekana an muri rusange kugabanya 80% mubunini bwa PCU.
Kuri Toyota, ibi nibyingenzi cyane kuberako PCU yonyine ishinzwe 25% byingufu zamashanyarazi mumodoka ya Hybride na mashanyarazi, hamwe na semiconductor ya PCU bingana na 20% yibihombo byose.
PCU ni kimwe mu bintu by'ingenzi mu binyabiziga bivangavanze n'amashanyarazi, kubera ko PCU ari yo ishinzwe gutanga amashanyarazi kuva muri bateri kugeza kuri moteri y'amashanyarazi, kugenzura ukuzenguruka kwa moteri y'amashanyarazi, gucunga ibishya no sisitemu yo kugarura. ingufu, hanyuma, muguhindura imikorere ya moteri yamashanyarazi hagati yikintu na moteri ikora.
Kugeza ubu, PCU igizwe nibintu byinshi bya elegitoroniki, icy'ingenzi muri byo kikaba imiyoboro itandukanye ya silicon, hamwe n'amashanyarazi atandukanye. Nukuri muburyo bwa tekinoroji ya semiconductor ikoreshwa muri PCU ubwo buhanga bushya bwa Toyota buza gukoreshwa, bukora neza mubice bitatu byingenzi: gukoresha ingufu, ingano nubushyuhe bwumuriro.
Toyota izi ko mugihe bateri zifite tekinoroji igezweho hamwe nubucucike bwingufu zitagaragara, zishobora guhuza neza indangagaciro zidasanzwe za (Ah na V), umutungo wonyine uzashobora kongera ingufu zingufu ni ugukora byose ibice by'amashanyarazi biri mubuyobozi bwa elegitoronike neza kandi birwanya.
Kazoza ka Toyota hamwe nabashoferi bashya karatanga ikizere - nubwo ibiciro byumusaruro bikiri hejuru yikubye inshuro 10 kugeza kuri 15 ugereranije nibisanzwe - urebye ubufatanye bumaze kugerwaho mugukwirakwiza ibyo bice hamwe nibizamini bimaze gukorwa mumuhanda byunguka 5% muri ntarengwa byemewe. Reba kuri videwo, impinduramatwara ya silicon karbide semiconductor ikora:
