UToyota uzibophelele ekuthatheni elinye inyathelo eliya phambili kuphuhliso lwezithuthi ezixubeneyo nezombane. Fumana inkqubo entsha esebenzisa iSilicon Carbide ekwakhiweni kweemodyuli zokulawula amandla, kunye nezithembiso zokusebenza kakuhle.
IToyota ibe yenye yeebrendi ezityale imali kakhulu kuphuhliso lolunye ubugcisa kwiimoto ezixubeneyo, kunye neDenso, kwintsebenziswano ethathe iminyaka engama-34 ehloniphekileyo.
Ngenxa yolu phando, iToyota ngoku inika isizukulwana esitsha seemodyuli zokulawula amandla (PCU) - eziziko lokusebenza kwezi zithuthi - usebenzisa enye yezinto ezinzima kakhulu ebusweni bomhlaba: Silicon Carbide (SiC) .
Ngokusetyenziswa kweSilicon Carbide (SiC) semiconductors kulwakhiwo lweePCU's - ngokonakalisa ii-silicon semiconductors zemveli - uToyota ubanga ukuba kunokwenzeka ukuphucula ukuzimela kwezithuthi ezixutyiweyo nezombane malunga ne-10%.
Kungaba yinzuzo encinci, kodwa kufuneka kuqatshelwe ukuba abaqhubi be-SiC bajongene nokulahlekelwa kwamandla kuphela kwe-1/10 ngexesha lokuhamba kwangoku, okuvumela ukunciphisa ubungakanani bamacandelo afana neekhoyili kunye ne-capacitors malunga ne-40%, emele i ngokubanzi 80% ukunciphisa ubukhulu PCU.
Kwi-Toyota, oku kubaluleke kakhulu kuba i-PCU yodwa inoxanduva lwe-25% yokulahlekelwa kwamandla kwi-hybrid kunye neenqwelo zombane, kunye ne-PCU semiconductors accounting ye-20% yelahleko iyonke.
I-PCU yenye yezona zinto zibaluleke kakhulu kwizithuthi ezixubileyo kunye nombane, kuba yi-PCU ejongene nokubonelela ngombane wangoku ukusuka kwiibhetri ukuya kwi-motor yombane, ukulawula ukujikeleza kwemoto yombane, ukulawula uhlaziyo kunye. inkqubo yokubuyisela amandla, kwaye ekugqibeleni, ngokutshintsha ukusebenza kwemoto yombane phakathi kweyunithi yokuqhubela phambili kunye neyunithi yokuvelisa.
Okwangoku, ii-PCU's zenziwe ngezinto ezininzi zombane, ezona zibalulekileyo kuzo zijika zibe zii-silicon semiconductors ezahlukeneyo, ezinamandla ombane ahlukeneyo kunye nokuchasana. Kuchanekileyo kwitekhnoloji ye-semiconductor esetyenziswa kwi-PCU ukuba le teknoloji entsha ye-Toyota iza kudlala, esebenza kakuhle kwiinkalo ezintathu ezithatha isigqibo: ukusetyenziswa kwamandla, ubungakanani kunye neempawu zokushisa.
I-Toyota iyazi ukuba ngelixa iibhetri ezinobuchwephesha obuphezulu kunye nobuninzi bamandla aphezulu zingabonakali, ezinokudibanisa ngokugqibeleleyo amaxabiso aphawulekayo (Ah kunye ne-V), ekuphela komthombo apho iya kukwazi ukwandisa ukusebenza kakuhle kwamandla kukwenza konke. amacandelo ombane ayinxalenye yolawulo lwe-elektroniki olusebenza ngakumbi kwaye luxhathisa.
Ikamva likaToyota naba baqhubi batsha liyathembisa – nangona iindleko zemveliso zisephezulu ngokuphindwe ka-10 ukuya kwali-15 kunezo ziqhelekileyo – kuthathelwa ingqalelo intsebenziswano esele ifikelelwe kubuninzi bala macandelo kunye novavanyo esele lwenziwe endleleni ngenzuzo ye-5% ubuncinci buqinisekisiwe. Jonga kwividiyo, uguquko olwenziwa yisilicon carbide semiconductors:
