Kutheni iimoto zombane zifuna i-800V?

Bobabini abavelisi kunye nabanikazi bemoto baphupha umphumo "wokutshaja imizuzu emi-5 kunye nokuqhuba i-200km".

Ukufezekisa esi siphumo, iimfuno ezimbini eziphambili kunye namanqaku eentlungu kufuneka asonjululwe:
Enye, kukuphucula kakhulu ukusebenza kokutshaja kwaye unyuse ngokukhawuleza isantya sokutshaja ibhetri.
Okwesibini, kukuphucula ukusebenza kakuhle kwesithuthi sonke kunye nokwandisa uluhlu lokuqhuba phantsi kwemeko efanayo yamandla.
Apha, sinokusebenzisa i-physics yesikolo samabanga aphakamileyo ukuqonda ngokufutshane: P=UI.Ngoko ukuba ufuna ukwandisa amandla, kukho iindlela ezimbini kuphela zokunyusa okwangoku okanye ukwandisa amandla ombane.
Nangona kunjalo, imisinga emikhulu iya kubangela ilahleko enkulu yobushushu ekutshajani imipu, iintambo kunye namacandelo aphambili ebhetri, kwaye umda ongaphezulu wokuphuculwa kwethiyori awumkhulu.Ngoko ke, indlela eya ekwandeni kwangoku "ayifikeleleki", hayi, kufuneka "ingabi kude kakhulu".
Ke, kuthekani ngokunyusa amandla ombane?
Xa inkqubo yangoku ihleli ingaguquguquki, amandla okutshaja aya kuphinda kabini njengesixhobo sombane, oko kukuthi, isantya esiphezulu sokutshaja siya kuphinda kabini, kwaye ixesha lokutshaja liya kufinyezwa kakhulu.Ukongeza, phantsi kwamandla afanayo okutshaja, ukuba i-voltage iphezulu, i-current ingancitshiswa, kwaye ucingo alufuni ukuba lube lukhulu, kwaye ukuxhathisa ubushushu bokusetyenziswa kwamandla ombane kuyancipha.

Ke ngoko, ukuba usasebenzisa ubungakanani bentambo yokutshaja eyi-400V, ungawongeza amandla okutshaja.Oku kuthetha ukuba phantsi kweqonga le-800V, iintambo zokutshaja ezincinci zingasetyenziswa.
Uphando lweHuawei lubonisa ukuba ukutshaja okukhawulezayo usebenzisa i-800V imowudi yevoltage ephezulu ixhasa ukutshaja kwamandla aphezulu angama-30% -80% SOC, ngelixa imowudi ephantsi yevoltage ephezulu yangoku inokwenza kuphela ukutshaja kwamandla aphezulu kwi-10% -20% yeSOC, kunye namandla okutshaja. yehla kakhulu kolunye uluhlu.ngokukhawuleza.Ingabonwa ukuba imowudi ye-800V ephezulu inokuxhasa ukutshaja okukhawulezayo okude.
Ukuphakama kokusebenza kakuhle kwesithuthi siphela, oku kuthetha ukuba phantsi kwemeko yangoku rhoqo, ukuphakama kwamandla ebhetri, amandla amakhulu emoto, kunye nokusebenza kakuhle kwe-motor drive.
Ngoko ke, i-platform ye-800V ephezulu ye-voltage inokufikelela ngokulula amandla aphezulu kunye ne-torque, kunye nokusebenza okungcono kokukhawuleza.Nangona ukuphuculwa kokusebenza kakuhle kokuzaliswa kwamandla okuziswa yi-800V kwizithuthi zombane kusemgangathweni, omnye wemiqobo enkulu ekuphunyezweni kwe-800V ngumba weendleko.

Ukuba ufuna ukwazi ngakumbi malunga noku, nceda uzive ukhululekile ukuqhagamshelana nathi.
