Bobabili abakhiqizi nabanikazi bezimoto baphupha ngomphumela "wokushaja imizuzu emi-5 nokushayela i-200km".
Ukufeza lo mphumela, izidingo ezimbili ezinkulu kanye namaphuzu obuhlungu kufanele axazululwe:
Okokuqala, ukuthuthukisa kakhulu ukusebenza kokushaja futhi ukhuphule ngokushesha isivinini sokushaja kwebhethri.
Okwesibili, iwukuthuthukisa ukusebenza kahle kwayo yonke imoto nokwandisa ibanga lokushayela ngaphansi kwesimo samandla esifanayo.
Lapha, singasebenzisa i-junior high school physics ukuze siqonde kafushane: P=UI. Ngakho-ke uma ufuna ukwandisa amandla, kunezindlela ezimbili kuphela zokwandisa okwamanje noma ukwandisa i-voltage.
Kodwa-ke, imisinga emikhulu izobangela ukulahlekelwa ukushisa okuphezulu ekushajeni izibhamu, izintambo kanye nezingxenye eziyinhloko zamabhethri wamandla, futhi umkhawulo ongaphezulu wokuthuthukiswa kwethiyori awumkhulu. Ngakho-ke, umgwaqo okhulayo wamanje "awufinyeleleki", cha, kufanele "ungabi kude kakhulu".
Ngakho-ke, kuthiwani ngokwandisa i-voltage?
Uma uhlelo lwamanje luhlala njalo, amandla okushaja azophinda kabili njenge-voltage yesistimu, okungukuthi, isivinini sokushaja esiphezulu sizophindeka kabili, futhi isikhathi sokushaja sizofinyezwa kakhulu. Ngaphezu kwalokho, ngaphansi kwamandla afanayo wokushaja, uma i-voltage iphakeme, i-current ingancishiswa, futhi ucingo aludingi ukuba lukhulu kakhulu, futhi ukumelana nokushisa kokushisa ukusetshenziswa kocingo nakho kuyancipha.
Ngakho-ke, uma usasebenzisa usayizi wokuqala wekhebula lokushaja elingu-400V, ungawandisa amandla okushaja. Lokhu kusho ukuthi ngaphansi kweplathifomu engu-800V, izintambo zokushaja ezincanyana zingasetshenziswa.
Ucwaningo lweHuawei lubonisa ukuthi ukushaja okusheshayo kusetshenziswa imodi ye-high-voltage engu-800V kusekela ukushaja kwamandla aphezulu angu-30% -80% SOC, kuyilapho imodi yamanje enevoltage ephansi ingakwazi ukushaja amandla aphezulu ku-10% -20% SOC, namandla okushaja. yehla kakhulu kwezinye izigaba. ngokushesha. Kuyabonakala ukuthi imodi ye-800V high-voltage ingasekela ukushaja okusheshayo okude.
Ukuphakama kokusebenza kahle kwayo yonke imoto, okusho ukuthi ngaphansi kwesimo samanje esingaguquki, ukuphakama kwe-voltage yebhethri, amandla emoto amakhulu, kanye nokusebenza kahle kokushayela kwemoto.
Ngakho-ke, isiteji se-high-voltage engu-800V singafinyelela kalula amandla aphezulu kanye ne-torque, kanye nokusebenza okungcono kokusheshisa. Nakuba ukuthuthukiswa kokusebenza kahle kokugcwalisa amandla okulethwa yi-800V ezimotweni zikagesi kusezingeni eliphezulu, esinye sezithiyo ezinkulu ekusetshenzisweni kwe-800V udaba lwezindleko.
Uma ufuna ukwazi okwengeziwe ngalokhu, sicela ukhululeke ukuxhumana nathi.
