Abakhiqizi beziteshi zokushaja izimoto:Ngokuqhubeka okuqhubekayo kobuchwepheshe bebhethri nezinkampani zezimoto ku-lightweight nakwezinye izindawo zokuthuthuka, uhla lwezimoto zikagesi luyaqhubeka nokuba ngcono, uhla lwamamodeli angaphezu kuka-1,000km luye lwambulwa ngokulandelana, ukukhathazeka kwemayela lemoto kagesi kuncishisiwe, kodwa ukushaja kuhamba kancane, ukushaja kunzima "ukulungisa ukukhathazeka kwamandla kagesi" kusavimbela ukuthuthukiswa kwemoto kagesi. Ubuchwepheshe bokushaja obukhona budinga ukuthi abathengi balinde imizuzu engama-40 noma isikhathi eside ukuze bagcwalise, ukuhamba ngeholide "ukushaja ihora, ukuklelisa amahora amane" sekubuhlungu kakhulu kubanikazi bezimoto zamandla amasha, ukuze ukugcwaliswa kabusha kukagesi ngokushesha kube lula njengokugcwalisa uphethiloli sekuphenduke isiqondiso semizamo ye-EV industry chain.
Abakhiqizi beziteshi zokushaja izimoto: Isistimu ye-high-voltage engu-800V + ukushaja okusheshayo kwezimoto zikagesi kungafinyelela isikhathi sokushaja esiyimizuzu eyi-10 nohlu lwamakhilomitha angama-300, olungaxazulula ngempumelelo ukukhathazeka kokugcwaliswa kabusha, futhi kulindeleke ukuthi kube umzila ojwayelekile wokushaja okusheshayo. Izinkampani zezimoto ezijwayelekile zasekhaya nezangaphandle sezivele zenze izakhiwo ezifanele, futhi amamodeli ambalwa we-800V azokhiqizwa ngobuningi ngo-2022. Kodwa ifakwe i-800V yesikhulumi semoto eshaja inqwaba yenqwaba yokushaja, ijubane lokushaja alifinyelele kulokho okulindelekile, abakwazi ukufeza ukushaja okusheshayo, ngaleyo ndlela inqwaba yenombolo idinga ukukhushulwa ekugcineni kwenqwaba yezimoto. zezigatshana zethrekhi zizozuza.
Okokuqala, yini ukushaja high voltage
Abakhiqizi beziteshi zokushaja izimoto:Ukushaja okusheshayo kuyashesha, iyunithi yokulinganisa ingashajwa izikhathi (C). Uma isiphindaphinda sokushaja sikhulu, isikhathi sokushaja siba mfishane.
Isiphindaphinda sokushaja (C) = yamanje yokushaja (mA) / umthamo olinganiselwe webhethri (mAh)
Isibonelo, uma umthamo webhethri ungu-4000mAh futhi yamanje yokushaja ifinyelela ku-8000mAh, isiphindaphindi sokushaja singu-8000/4000 = 2C.
Abakhiqizi beziteshi zokushaja izimoto:Ukushaja okuphezulu akukona u-0% -100% wenkokhiso yenziwa ngokushaja okuphezulu kwamanje. Imodi yokushaja enengqondo ihlukaniswe izigaba ezintathu, isigaba 1: isimo sokushaja kwangaphambili; isigaba 2: ukushaja kwamanje okuphezulu okungaguquki; isigaba sesi-3: ukushaja i-voltage njalo.
Abakhiqizi beziteshi zokushaja izimoto:Isigaba 1 sokushajwa kwangaphambili sidlala indima yokuvikela iseli yebhethri, isigaba 2 yilokho esikubiza ngokuthi yizinga eliphezulu lokushaja, ububanzi bamandla ale nqubo ngokuvamile buba ku-20% -80%; Isiteji sesi-3 sokushaja i-voltage engaguquki kuhloswe ngaso ukukhawulela i-voltage, ukuvimbela iseli yebhethri ekubeni i-over-voltage, engalimaza ukwakheka kwebhethri.
1, Abakhiqizi beziteshi zokushaja izimoto: ukushaja okusheshayo kudinga ukuthuthukisa amandla okuphela kokushaja kanye nesiphindaphindi sokushaja kwebhethri/ukukhipha
Kunezindlela ezimbili zokushaja eziyinhloko zama-EV: ukushaja okusheshayo kwe-DC kanye nokushaja okungasheshi kwe-AC.
Abakhiqizi beziteshi zokushaja izimoto:Ukushaja okunensayo kwe-AC kuhambisana nendawo yokushaja ekhaya noma ezindaweni zokupaka izimoto zomphakathi, amandla okushaja mancane ukusuka kuma-kilowatts ambalwa ukuya kuma-kilowatts amaningi, ngokuvamile kuthatha amahora angu-8-10 ukuze ushajwe ngokugcwele. Ukushaja okuhamba kancane kwe-AC kusebenzisa amandla angu-220V AC asuka kugridi ngokuqondile, futhi kuyiguqulela kumandla e-DC ngesiguquli se-AC/DC esingaphakathi kweshaja engaphakathi ebhodini ye-OBC ukuze inikeze ibhethri le-EV. Abakhiqizi beziteshi zokushaja izimoto:Ngenxa yamandla aphansi wokushaja, amandla esiguquli se-AC/DC esakhelwe ku-OBC esebhodini ngokuvamile aphansi, futhi izindleko ziphansi.
Abakhiqizi beziteshi zokushaja izimoto:Ukushaja okusheshayo kwe-DC ngokuvamile kuhambisana nezimo zokushaja emigwaqweni yezimoto/ohambweni olude, lapho amandla afinyelela amakhulu ama-kilowatts futhi kuthatha amahora angu-1-2 kuphela ukushaja ngokugcwele. Ingqikithi yokushaja okusheshayo kwe-DC iwukudlulisa amandla aphezulu e-AC/DC endaweni yokushaja esheshayo, lapho iposi yokushaja ye-DC iguqula amandla e-AC ukusuka kugridi ibe amandla aphezulu e-DC ngesilungisi sokushaja ibhethri lemoto ngokuqondile. Amandla aphezulu wokushaja okusheshayo angafinyelela ku-350kW noma ngisho ku-480kW, futhi isikhathi sokushaja esisheshayo kulindeleke ukuthi sehliswe sibe ngaphansi kwamaminithi angu-30, futhi ngokuzayo singacindezelwa sibe ngaphansi kwemizuzu eyishumi.
Abakhiqizi beziteshi zokushaja izimoto:Isibhamu esishajayo sokushaja okusheshayo kwe-DC "ibhuloho" lohlelo lokushaja okusheshayo lwe-DC, elenza ukudlulisa nokuguqula amandla kanye nolwazi phakathi kweshaja nemoto. Isibhamu sikazwelonke esijwayelekile sika-HUBER+SUHNER sika-liquid-cooled, i-RADOX® HPC 600, siyakwazi ukuzuza ukushajwa okuqhubekayo okungafika ku-600A (kufika ku-800A empilweni yangempela), ngokusebenza okungu-600kW/1000V. I-RADOX® HPC 600 inikezela ngokushaja okuqhubekayo okungu-600A (okukalwa kufika ku-800A), ukusebenza kwesistimu okungu-600kW/1000V, isistimu yokulinganisa esekulungele ukusetshenziswa, abathintwayo abangase bathathelwe indawo impilo yesevisi ende, ukuphepha okuphakeme ngesilinganiso se-IP67, kanye ne-CCS1 ne-CCS2 interface. Ingakwazi ukubona ukushaja okusheshayo okusebenza kahle futhi okuvamile, okungagcina isivinini sokushaja okuphezulu, isiqinisekiso sokuphepha sokushaja, ukunciphisa isisindo semishini kanye nezindleko zokuyilungisa, futhi iyinketho engcono yezindawo zokushaja ezinkulu ezipholile uketshezi.
Isithombe
2, Abakhiqizi besiteshi sokushaja imoto:Thuthukisa isivinini sokushaja esisheshayo: isidingo sokuthuthukisa amandla okuphela kokushaja kanye nokushaja kwebhethri/isiphindaphindi sokushajwa ngesikhathi esifanayo.
Ukushaja amandla asebenzayo yinani elincane lamandla okushaja namandla okushaja ibhethri, futhi ukuze uthuthukise isivinini sokushaja esisheshayo, kuyadingeka ukuthuthukisa amandla okushaja nezinga lokushaja/lokukhipha ibhethri ngesikhathi esifanayo.
Abakhiqizi beziteshi zokushaja izimoto:Amandla okushaja (ifomula P=UI) anganyuswa ngokukhuphula i-voltage noma i-current. Uma sithatha iPorsche njengesibonelo, iPorsche Taycan iyimodeli yokuqala ukwendlala iplatifomu engu-800V yamandla kagesi aphezulu, futhi njengommeleli ojwayelekile womzila wamandla kagesi aphezulu, amandla ayo okushaja afinyelela ku-350kW.
Okwesibili, izinzuzo kanye nokubi kokushajwa kwamandla kagesi aphezulu kanye nesimo samanje sokuthuthuka.
