Abakhiqizi kanye nabanikazi bezimoto baphupha ngomphumela "wokushaja imizuzu emi-5 nokushayela amakhilomitha angama-200".
Ukuze kufezwe lo mphumela, izidingo ezimbili ezinkulu kanye namaphuzu obuhlungu kumele kuxazululwe:
Okokuqala, ukuthuthukisa kakhulu ukusebenza kokushaja nokukhulisa isivinini sokushaja ibhethri ngokushesha.
Okwesibili, ukuthuthukisa ukusebenza kahle kwemoto yonke nokwandisa ibanga lokushayela ngaphansi kwesimo samandla esifanayo.
Lapha, singasebenzisa i-junior high school physics ukuze siqonde kafushane: P=UI. Ngakho-ke uma ufuna ukukhulisa amandla, kunezindlela ezimbili kuphela zokwandisa ugesi noma ukukhulisa i-voltage.
Kodwa-ke, imisinga emikhulu izobangela ukulahlekelwa okukhulu kokushisa ezibhamini zokushaja, izintambo kanye nezingxenye eziyinhloko zamabhethri kagesi, futhi umkhawulo ophezulu wokuthuthukiswa kwemfundiso awumkhulu. Ngakho-ke, indlela eya ekukhuleni komsinga "ayifinyeleleki", cha, akufanele ibe "kude kakhulu".
Ngakho-ke, kuthiwani ngokwandisa i-voltage?
Uma ugesi wesistimu uhlala ungaguquki, amandla okushaja azophindeka kabili njenge-voltage yesistimu, okungukuthi, isivinini sokushaja esiphezulu sizophindeka kabili, futhi isikhathi sokushaja sizofinyezwa kakhulu. Ngaphezu kwalokho, ngaphansi kwamandla afanayo okushaja, uma ugesi uphakeme, ugesi ungancishiswa, futhi ucingo aludingi ukuba lukhulu kangako, futhi ukusetshenziswa kwamandla okushisa okumelana nentambo nakho kuncishisiwe.
Ngakho-ke, uma usasebenzisa usayizi wekhebula lokushaja elingu-400V lokuqala, ungandisa amandla okushaja. Lokhu kusho ukuthi ngaphansi kwepulatifomu engu-800V, kungasetshenziswa izintambo zokushaja ezincane.
Ucwaningo lwe-Huawei lubonisa ukuthi ukushaja okusheshayo kusetshenziswa imodi ye-800V high-voltage kusekela ukushaja kwamandla okuphezulu okungu-30%-80% SOC, kuyilapho imodi ye-high-current enamandla aphansi ingenza kuphela ukushaja kwamandla okuphezulu ku-10%-20% SOC, futhi amandla okushaja ehla kakhulu kwamanye amabanga. Kungabonakala ukuthi imodi ye-800V high-voltage ingasekela ukushaja okusheshayo okude.
Uma ukusebenza kahle kwemoto yonke kuphakeme, okusho ukuthi ngaphansi kwesimo samandla kagesi angaguquki, i-voltage yebhethri iphakeme, amandla emoto aba maningi, futhi ukusebenza kahle kwe-drive yemoto kuphakeme.
Ngakho-ke, ipulatifomu ye-800V high-voltage ingafinyelela kalula amandla aphezulu kanye ne-torque, kanye nokusebenza okungcono kokusheshisa. Nakuba ukuthuthukiswa kokusebenza kahle kokugcwalisa kabusha amandla okulethwa yi-800V ezimotweni zikagesi kuyinto esezingeni eliphezulu, esinye sezithiyo ezinkulu ekusetshenzisweni kwe-800V yinkinga yezindleko.
Uma ufuna ukwazi okwengeziwe ngalokhu, sicela ukhululeke ukuxhumana nathi.
