I-Toyota izimisele ngokuthatha elinye igxathu eliya phambili ekuthuthukisweni kwezimoto eziyingxubevange nezisebenza ngogesi. Zitholele uhlelo olusha olusebenzisa i-Silicon Carbide ekwakhiweni kwamamojula esilawuli samandla, anezithembiso zokusebenza kahle kakhulu.
UToyota ube ngolunye lwezinkampani ezitshale imali eningi ekuthuthukisweni kobunye ubuchwepheshe bezimoto eziyingxubevange, kanye neDenso, ngokubambisana osekuthathe iminyaka engu-34 ehloniphekile.
Ngenxa yalolu cwaningo, iToyota manje yethula isizukulwane esisha samamojula okulawula amandla (PCU) - okuyisikhungo sokusebenza kulezi zimoto - isebenzisa enye yezinto ezilukhuni kakhulu ebusweni bomhlaba: I-Silicon Carbide (SiC) .
Ngokusebenzisa ama-semiconductors e-Silicon Carbide (SiC) ekwakhiweni kwama-PCU's - ngokulimaza ama-silicon semiconductors endabuko - i-Toyota ithi kungenzeka ukuthuthukisa ukuzimela kwezimoto ezihlanganisiwe nezikagesi cishe ngo-10%.
Kungase kube inzuzo encane, kodwa kufanele kuqashelwe ukuthi abaqhubi be-SiC banesibopho sokulahlekelwa kwamandla ka-1/10 kuphela ngesikhathi sokugeleza kwamanje, okuvumela ukunciphisa usayizi wezingxenye ezifana namakhoyili nama-capacitor cishe ngo-40%, omele i kukonke ukuncishiswa okungu-80% kusayizi we-PCU.
KwaToyota, lokhu kubaluleke kakhulu njengoba i-PCU iyodwa inesibophezelo sokulahlekelwa kwamandla okungama-25% ezimotweni ezixubile nezikagesi, kanti ama-semiconductors e-PCU ahlanganisa u-20% wengqikithi yokulahlekelwa.
I-PCU ingenye yezingxenye ezibaluleke kakhulu ezimotweni ezixubile nezikagesi, ngoba yi-PCU enesibopho sokuhlinzeka amandla kagesi ukusuka kumabhethri kuya kumotho kagesi, ukulawula ukujikeleza kwemoto kagesi, yokuphatha ukuvuselelwa kanye nokuvuselelwa kabusha. Amandla, futhi ekugcineni, ngokushintsha ukusebenza kwenjini kagesi phakathi kweyunithi yokuqhubela phambili kanye neyunithi ekhiqizayo.
Njengamanje, ama-PCU enziwe ngezinto ezimbalwa ze-elekthronikhi, ezibaluleke kakhulu eziphenduka ama-silicon semiconductors ahlukahlukene, anamandla ahlukene kagesi nokumelana. Kukubuchwepheshe be-semiconductor obusetshenziswa kwi-PCU lapho kungena khona lobu buchwepheshe obusha be-Toyota, obusebenza kahle emikhakheni emithathu ebalulekile: ukusetshenziswa kwamandla, ubukhulu kanye nezakhiwo ezishisayo.
I-Toyota iyazi ukuthi nakuba amabhethri anobuchwepheshe obuthuthuke kakhulu obunamandla amakhulu angaveli, angahlanganisa kahle amanani aphawulekayo (Ah no-V), okuwukuphela kwensiza lapho ezokwazi khona ukwandisa ukusebenza kahle kwamandla ukwenza konke. izingxenye zikagesi eziyingxenye yokuphathwa kwe-elekthronikhi ezisebenza kahle kakhulu futhi zimelana.
Ikusasa likaToyota nalaba bashayeli abasha liyathembisa - naphezu kwezindleko zokukhiqiza zisephezulu ngokuphindwe ka-10 kuya kwayi-15 kunezijwayelekile - uma kubhekwa ukubambisana osekufinyelelwe ekugcwaliseni lezi zingxenye kanye nokuhlolwa osekwenziwe emgwaqeni okuzuzwe ngo-5% ubuncane obuqinisekisiwe. Buka ngevidiyo, uguquko olwenziwa ama-silicon carbide semiconductors:
