Toyota yadzipereka kuchitapo kanthu pakukula kwa magalimoto osakanizidwa ndi magetsi. Dziwani njira yatsopano yomwe imagwiritsa ntchito Silicon Carbide pomanga ma module owongolera mphamvu, ndikulonjeza kuchita bwino kwambiri.
Toyota yakhala imodzi mwazinthu zomwe zayika ndalama zambiri pakupanga ukadaulo wina wamagalimoto osakanizidwa, pamodzi ndi Denso, mumgwirizano womwe wakhalapo kwa zaka 34 zolemekezeka.
Chifukwa cha kafukufukuyu, Toyota tsopano ikupereka mbadwo watsopano wa ma modules owongolera mphamvu (PCU) - omwe ndi malo ogwirira ntchito m'magalimotowa - pogwiritsa ntchito chimodzi mwazinthu zovuta kwambiri padziko lapansi: Silicon Carbide (SiC) .
Pogwiritsa ntchito Silicon Carbide (SiC) semiconductors pomanga PCU's - powononga ma semiconductors achikhalidwe cha silicon - Toyota imati ndizotheka kupititsa patsogolo kudziyimira pawokha kwa magalimoto osakanizidwa ndi magetsi pafupifupi 10%.
Zitha kukhala zopindulitsa pang'ono, koma ziyenera kuzindikirika kuti ma conductor a SiC ali ndi udindo wotaya mphamvu ya 1/10 yokha panthawi yomwe ikuyenda, yomwe imalola kuchepetsa kukula kwa zigawo monga ma coils ndi capacitors pafupifupi 40%, kuyimira 80% kuchepetsa kukula kwa PCU.
Kwa Toyota, izi ndizofunikira makamaka popeza PCU yokha ndiyomwe imayambitsa 25% ya kutayika kwa mphamvu mu magalimoto osakanizidwa ndi magetsi, pomwe PCU semiconductors amawerengera 20% ya zotayika zonse.
PCU ndi imodzi mwazinthu zofunika kwambiri pamagalimoto osakanizidwa ndi magetsi, chifukwa ndi PCU yomwe ili ndi udindo wopereka mphamvu yamagetsi kuchokera ku mabatire kupita ku mota yamagetsi, kuwongolera kuzungulira kwa injini yamagetsi, kuyang'anira kusinthika ndi kusinthika. mphamvu, ndipo potsiriza, posintha ntchito ya galimoto yamagetsi pakati pa gawo loyendetsa ndi gawo lopangira.
Pakadali pano, ma PCU amapangidwa ndi zinthu zingapo zamagetsi, zofunika kwambiri zomwe zimakhala ma semiconductors osiyanasiyana a silicon, okhala ndi mphamvu zosiyanasiyana zamagetsi komanso kukana. Ndi ndendende mu ukadaulo wa semiconductor womwe umagwiritsidwa ntchito mu PCU kuti ukadaulo watsopano wa Toyota ukubwera, womwe umagwira bwino ntchito m'magawo atatu ofunika: kugwiritsa ntchito mphamvu, kukula ndi kutentha.
Toyota ikudziwa kuti ngakhale mabatire omwe ali ndi ukadaulo wapamwamba kwambiri wokhala ndi kachulukidwe kamphamvu kwambiri samawoneka, omwe amatha kuphatikiza bwino kwambiri (Ah ndi V), gwero lokhalo lomwe lingathe kuwonjezera mphamvu zamagetsi ndikupanga zonse. zida zamagetsi zomwe zili mbali ya kayendetsedwe kamagetsi kogwira mtima komanso kosasunthika.
Tsogolo la Toyota ndi madalaivala atsopanowa likulonjeza - ngakhale kuti ndalama zopangira zimakhala zokwera kwambiri nthawi 10 mpaka 15 kuposa zachizolowezi - chifukwa cha mgwirizano womwe wapezeka kale pakuwonjezeka kwa zigawozi ndi mayesero omwe anachitika kale pamsewu ndi phindu la 5% mu zotsimikizika zochepa. Onani kudzera muvidiyoyi, kusintha komwe ma silicon carbide semiconductors amachita:
