Ukukhathazeka ngebanga kuyisithiyo esikhulu kunazo zonke esikhawulela ukuchuma kwemakethe yezimoto zikagesi, futhi incazelo ngemuva kokuhlaziywa ngokucophelela kokukhathazeka kwebanga "ukubekezela isikhashana" kanye "nokushaja kancane". Njengamanje, ngaphezu kwempilo yebhethri, kunzima ukwenza inqubekelaphambili, ngakho-ke "ukushaja okusheshayo" kanye "ne-supercharge" kugxilwe kwesakhiwo samanje sezinkampani zezimoto ezihlukahlukene. Ngakho i800V high voltageumsamo waba khona.
Kubathengi abajwayelekile, inkundla ye-800V high-voltage ekhuthazwa izinkampani zezimoto iyitemu lobuchwepheshe kuphela, kodwa njengobuchwepheshe obubalulekile esikhathini esizayo, iphinde ihlobane nolwazi lwemoto yomthengi, futhi kufanele sibe nokuqonda okujwayelekile kwalobu buchwepheshe obusha. . Ngakho-ke, leli phepha lizokwenza ukuhlaziywa okujulile kwesiteji sokucindezela okuphezulu kwe-800V kusuka ezicini ezahlukene ezifana nesimiso, isidingo, ukuthuthukiswa kanye nokufika.
Kungani udinga inkundla ye-800V?
Eminyakeni emibili edlule, ngokunyuka kancane kancane kwenani lezimoto zikagesi, inani lenqwaba yokushaja liye lakhuphuka kanyekanye, kodwa isilinganiso senqwaba asizange sehle. Ekupheleni kuka-2020, "i-car-pile ratio" yezimoto zasekhaya zamandla amasha ngu-2.9: 1 (inombolo yezimoto iyizigidi ezingu-4.92 kanye nenani lenqwaba yokushaja i-1.681 million). Ngo-2021, isilinganiso semoto nenqwaba sizoba ngu-3: 1, esingeke sehle kodwa sikhuphuke. Umphumela uba ukuthi isikhathi somugqa side kunesikhathi sokushaja.
Khona-ke endabeni yenani lokushaja izinqwaba azikwazi ukuqhubeka, ukuze kuncishiswe isikhathi sokushaja izinqwaba, ubuchwepheshe bokushaja okusheshayo buyadingeka kakhulu.
Ukwenyuka kwejubane lokushaja kungaqondakala kalula njengokukhuphuka kwamandla okushaja, okungukuthi, P = U·I ku-P (P: amandla okushaja, U: i-voltage yokushaja, I: yamanje yokushaja). Ngakho-ke, uma ufuna ukwandisa amandla okushaja, gcina eyodwa ye-voltage noma yamanje ingashintshiwe, ukukhulisa i-voltage noma yamanje kungathuthukisa amandla okushaja. Ukwethulwa kwesikhulumi samandla kagesi aphezulu ukuthuthukisa ukusebenza kahle kokushaja kokuphela kwemoto nokubona ukushajwa kabusha okusheshayo kokuphela kwemoto.
Ipulatifomu ye-800Vezimotweni zikagesi kuyisinqumo esijwayelekile sokushaja ngokushesha. Kumabhethri wamandla, ukushaja okusheshayo empeleni kuwukwenyusa ukushaja kwamanje kweseli, okubuye kwaziwe njengesilinganiso sokushaja; Njengamanje, izinkampani eziningi zezimoto zisesigabeni samakhilomitha ayi-1000 wokushayela, kodwa ubuchwepheshe bamanje bebhethri, noma ngabe buthuthukisiwe baba ngamabhethri aqinile, budinga nephakethe lebhethri elinamandla angaphezu kuka-100kWh, okuzoholela ekutheni ukwanda kwenani lamaseli, uma i-platform ye-400V evamile iqhubeka nokusetshenziswa, inani lamaseli ahambisanayo liyakhula, okuholela ekwandeni kwamanje webhasi. Iletha inselele enkulu ekucacisweni kwentambo yethusi kanye neshubhu yepayipi yokushisa.
Ngakho-ke, kuyadingeka ukushintsha uchungechunge lwesakhiwo esihambisanayo samaseli ebhethri kuphakethe lebhethri, ukunciphisa ukufana nokwandisa uchungechunge, ukuze kwandiswe ukushaja kwamanje ngenkathi kugcinwa inkundla yamanje ebangeni leleveli elinengqondo. Kodwa-ke, njengoba inani lochungechunge landa, i-voltage yokuphela kwephakethe yebhethri izokwenyuswa. Amandla kagesi adingekayo kuphakethe lebhethri elingu-100kWh ukuze kutholakale ukushajwa okusheshayo okungu-4C cishe ku-800V. Ukuze uhambisane nomsebenzi wokushaja osheshayo wawo wonke amazinga wamamodeli, i-800V yezakhiwo zikagesi yisinqumo esingcono kakhulu.
