Toyota yakazvipira kutora rimwe danho rekufambira mberi mukugadzirwa kwemotokari dzakasanganiswa nedzemagetsi. Tsvaga hurongwa hutsva hunoshandisa Silicon Carbide mukuvaka kwemagetsi controller modules, ine zvipikirwa zvekushanda kukuru.
Toyota yanga iri imwe yemhando yakaisa mari yakawanda mukuvandudza mamwe matekinoroji emotokari dzakasanganiswa, pamwe neDenso, mumubatanidzwa wakagara kwemakore anoremekedzwa makumi matatu nemana.
Somugumisiro wekutsvakurudza uku, Toyota ikozvino inopa chizvarwa chitsva chemagetsi controller modules (PCU) - iyo inzvimbo yekushanda mumotokari idzi - kushandisa chimwe chezvinhu zvakaoma zvikuru pamusoro penyika: Silicon Carbide (SiC) .
Kuburikidza nekushandiswa kweSilicon Carbide (SiC) semiconductors mukuvaka PCU's - mukukanganisa echinyakare silicon semiconductors - Toyota inoti zvinokwanisika kuvandudza kuzvitonga kwehybrid nemagetsi mota nezvikamu gumi muzana.
Inogona kunge iri mukana wepakati, asi zvinofanirwa kucherechedzwa kuti maSiC conductors ane mhosva yekurasikirwa kwesimba kwe1/10 chete panguva yekuyerera kwazvino, iyo inobvumira kudzikisa saizi yezvikamu zvakaita semakoiri uye capacitor neanenge 40%, inomiririra zvakazara 80% kuderedzwa kwePCU saizi.
KuToyota, izvi zvinonyanya kukosha sezvo PCU yega inokonzera 25% yekurasikirwa kwesimba mumotokari dzakasanganiswa uye dzemagetsi, nePCU semiconductors inoverengera 20% yekurasikirwa kwese.
Iyo PCU ndechimwe chezvinhu zvakakosha mumotokari dzakasanganiswa uye dzemagetsi, nekuti ndiyo PCU ine basa rekupa magetsi kubva kumabhatiri kuenda kumota yemagetsi, yekudzora kutenderera kwemota yemagetsi, yekugadzirisa kuzvarwa patsva uye. recovery system.simba, uye pakupedzisira, nekuchinja kushanda kwemota yemagetsi pakati peiyo propulsion unit uye generating unit.
Parizvino, maPCU anoumbwa nezvinhu zvakati wandei zvemagetsi, izvo zvakanyanya kukosha zvinozova akasiyana silicon semiconductors, ane akasiyana emagetsi simba uye kuramba. Izvo chaizvo mune tekinoroji yesemiconductor yakashandiswa muPCU kuti iyi tekinoroji nyowani yeToyota inopinda, iyo inoshanda zvakanyanya mundima nhatu dzakasimba: mashandisiro esimba, saizi uye zvivakwa zvinopisa.
Toyota inoziva kuti nepo mabhatiri ane tekinoroji yepamusoro ane simba rakanyanya density asingaratidzike, ayo anogona kunyatso batanidza zvinoshamisa kukosha kwe (Ah neV), iyo chete sosi yainokwanisa kuwedzera simba rekushandisa kugadzira zvese. zvikamu zvemagetsi izvo zviri chikamu chemagetsi manejimendi zvakanyanya uye zvinodzivirira.
Remangwana reToyota nevatyairi vatsva ava riri kuvimbisa - kunyangwe mitengo yekugadzira ichiri kukwira zvakapetwa ka10 kusvika ka15 pane zvemazuva ose - zvichipiwa kudyidzana kwatovepo mukuwanda kwezvikamu izvi uye bvunzo dzakatoitwa munzira nekubudirira kwe5% shoma yakavimbiswa. Tarisa kuburikidza nevhidhiyo, shanduko inoitwa nesilicon carbide semiconductors:
