Abavelisi besikhululo sokutshaja iimoto:Ngenkqubela phambili eqhubekayo yetekhnoloji yebhetri kunye neenkampani zemoto kubunzima obukhaphukhaphu kunye nezinye iindawo zophuhliso, uluhlu lwezithuthi zombane luyaqhubeka nokuphucuka, uluhlu lweemodeli ezingaphezu kwe-1,000km ziye zatyhilwa enye emva kwenye, ukuxhalaba kweemayile zemoto yombane kuyathomalaliswa, kodwa ukutshaja kuyacotha, ukutshaja kunzima "ukwenza ixhala lamandla ombane" lokuthintela uphuhliso lombane. Ubuchwephesha bokutshaja obukhoyo bufuna ukuba abathengi balinde imizuzu engama-40 okanye ixesha elide ukuze bazalise, ukuhamba kweeholide "ukutshaja iyure, ukufola iiyure ezine" kuye kwaba yintlungu enzulu yamathambo kubanikazi bezithuthi zamandla amatsha, ukwenzela ukuba ukuzaliswa ngokukhawuleza kombane njengento efanelekileyo njengoko i-refueling iye yaba ngulwalathiso lwemigudu ye-EV industry chain chain.
Abavelisi besikhululo sokutshaja iimoto: Inkqubo ye-800V ephezulu ye-voltage + ukutshaja okukhawulezayo kwezithuthi zombane kunokufikelela ixesha lokutshaja lemizuzu eyi-10 kunye noluhlu lweekhilomitha ezingama-300, ezinokusombulula ngokufanelekileyo ukuxhalaba kokuzaliswa kwakhona, kwaye kulindeleke ukuba ibe yeyona ndlela iphambili yokutshaja ngokukhawuleza. Iinkampani zeemoto zasekhaya kunye nezangaphandle sele zenze izicwangciso ezifanelekileyo, kwaye iimodeli ezininzi ze-800V ziya kuveliswa ngobuninzi ngo-2022. Kodwa zixhotyiswe nge-800V high-voltage platform imoto yokutshaja kwi-charge yokutshaja imfumba yokutshaja, isantya sokutshaja asifikeleli kwizinto ezilindelekileyo, azikwazi ukufezekisa ukutshaja okukhawulezayo, ngoko ke i-industrial idinga i-car chain ekupheleni, kunye nenani le-car chain ekupheleni. amacandelwana omzila aya kuzuza.
Okokuqala, yintoni ukutshaja kombane ophezulu
Abavelisi besikhululo sokutshaja iimoto:Ukutshaja okukhawulezayo kukutshaja ngokukhawuleza, iyunithi yokulinganisa inokuhlawuliswa amaxesha (C). Ukuba sikhulu isiphindaphindi sokutshaja, kokukhona liba lifutshane ixesha lokutshaja.
Isiphindaphindi sokutshaja (C) = ukutshaja okwangoku (mA) / umthamo okalelwe ibhetri (mAh)
Ngokomzekelo, ukuba umthamo webhetri yi-4000mAh kwaye umbane wokutshaja ufikelela kwi-8000mAh, umphindaphindi wokutshaja ngu-8000/4000 = 2C.
Abavelisi besikhululo sokutshaja iimoto:Ixabiso eliphezulu lokutshaja ayi-0%-100% yentlawulo yenziwa kukutshaja okuphezulu kwangoku. Imowudi yokutshaja efanelekileyo ihlukaniswe ngamanqanaba amathathu, isigaba 1: i-pre-chargeing state; Inqanaba lesi-2: ukutshaja kwangoku okuphezulu kwangoku okuqhubekayo; isigaba 3: ukutshaja ombane rhoqo.
Abavelisi bezikhululo zokutshaja iimoto: Inqanaba loku-1 lokutshaja kwangaphambili lidlala indima yokukhusela iseli yebhetri, inqanaba lesi-2 yinto esiyibiza ngokuba yinqanaba eliphezulu lokutshaja, uluhlu lwamandla lwale nkqubo luhlala lukwi-20% -80%; Inqanaba lesi-3 lokutshaja rhoqo kwe-voltage lijolise ekunciphiseni i-voltage, ukuthintela iseli yebhetri kwi-over-voltage, enokonakalisa isakhiwo sebhetri.
I-1, abavelisi besikhululo sokutshaja iimoto: ukutshaja okukhawulezayo kufuna ukuphucula amandla esiphelo sokutshaja kunye nentlawulo yebhetri / ukukhupha ukuphindaphinda
Kukho iindlela ezimbini eziphambili zokutshaja ii-EVs: ukutshaja ngokukhawuleza kwe-DC kunye nokutshaja okucothayo kwe-AC.
Abavelisi besikhululo sokutshaja iimoto: Ukutshaja okucothayo kwe-AC kuhambelana nendawo yokutshaja ekhaya okanye kwiipaki zeemoto zasekuhlaleni, amandla okutshaja mancinci ukusuka kwiikilowatts ezimbalwa ukuya kumashumi eekilowatts, adla ngokuthatha iiyure ezisi-8 ukuya kwezili-10 ukuze ahlawulwe ngokupheleleyo. Ukutshaja okucothayo kwe-AC kusebenzisa i-220V AC amandla asuka ngqo kwigridi, kwaye iyiguqulela kumandla e-DC ngokusebenzisa isiguquli se-AC/DC ngaphakathi kwitshaja ekwibhodi ye-OBC ukubonelela ngebhetri ye-EV. Abavelisi besikhululo sokutshaja iimoto: Ngenxa yombane ophantsi wokutshaja, amandla oguqulelo lwe-AC / DC olwakhiwe kwi-OBC ekwibhodi luhlala luphantsi, kwaye iindleko ziphantsi.
Abavelisi besikhululo sokutshaja iimoto: Ukutshaja okukhawulezayo kweDC ngokuqhelekileyo kuhambelana neemeko zokutshaja kwiimoto ezihamba ngeendlela/iihambo ezinde, apho amandla afikelela kumakhulu eekilowatts kwaye kuthatha kuphela iiyure ezi-1-2 ukutshaja ngokupheleleyo. Undoqo we-DC yokutshaja ngokukhawuleza kukudlulisa amandla aphezulu e-AC / DC kwisithuba sokutshaja ngokukhawuleza, apho isithuba sokutshaja kwe-DC siguqula amandla e-AC ukusuka kwigridi ukuya kumandla aphezulu e-DC ngokusebenzisa i-rectifier ukutshaja ibhetri yesithuthi ngokuthe ngqo. Amandla aphezulu okutshaja ngokukhawuleza anokufikelela kuma-350kW okanye ama-480kW, kwaye ixesha lokutshaja elikhawulezayo kulindeleke ukuba lincitshiswe libe ngaphantsi kwemizuzu engama-30, kwaye kwixesha elizayo lisenokucinezelwa libe ngaphantsi kwemizuzu elishumi.
Abavelisi besikhululo sokutshaja iimoto:Umpu otshajayo wokutshaja ngokukhawuleza kwe-DC "yibhulorho" yenkqubo yokutshaja ngokukhawuleza kwe-DC, eyenza ugqithiso kunye noguqulo lwamandla kunye nolwazi phakathi kwetshaja kunye nesithuthi. Umpu wesizwe oqhelekileyo we-HUBER+SUHNER wesizwe, i-RADOX® HPC 600, iyakwazi ukuphumeza ukutshajisa okuqhubekayo ukuya kuthi ga kwi-600A (ukuya kuthi ga kwi-800A kubomi bokwenyani), kunye nokusebenza kwe-600kW/1000V. I-RADOX® HPC 600 inikezela nge-600A ukutshaja okuqhubekayo (kulinganiswa ukuya kwi-800A), ukusebenza kwenkqubo ye-600kW / 1000V, inkqubo yokulinganisa i-metering ekulungele ukusetyenziswa, oonxibelelwano olunokutshintshwa ubomi obude benkonzo, ukhuseleko oluphezulu kunye nokulinganisa kwe-IP67, kunye ne-CCS1 kunye ne-CCS2 interfaces. Iyakwazi ukubona ukutshaja ngokukhawuleza okusebenzayo kunye nokufanelekileyo, okunokugcina isantya sokutshaja okuphezulu, isiqinisekiso sokhuseleko lokutshaja, ukunciphisa ubunzima besixhobo kunye neendleko zokulondolozwa, kwaye lukhetho olungcono kwizibonelelo zokutshaja ezipholileyo zolwelo.
Umfanekiso
2, Abavelisi besikhululo sokutshaja iimoto: Phucula isantya sokutshaja ngokukhawuleza: imfuno yokuphucula amandla okuphela kokutshaja kunye nokutshaja kwebhetri / ukukhupha umphindaphindi ngaxeshanye.
Ukutshaja amandla asebenzayo lixabiso elincinci lokutshaja amandla kunye namandla okutshaja ibhetri, kunye nokuphucula isantya sokutshaja ngokukhawuleza, kuyimfuneko ukuphucula amandla okutshaja kunye nokutshaja kwebhetri / izinga lokukhupha ngexesha elinye.
Abavelisi besikhululo sokutshaja iimoto:Amandla okutshaja (ifomula P=UI) anokongezwa ngokunyusa amandla ombane okanye akhoyo. Ukuthatha umzekelo wePorsche, iPorsche Taycan yimodeli yokuqala yokubeka iqonga le-800V high-voltage, kwaye njengommeli oqhelekileyo wendlela yombane ophezulu, amandla ayo okutshaja afikelele kuma-350kW.
Okwesibini, iingenelo kunye nokungalunganga kokutshaja kwe-voltage ephezulu kunye nemeko yophuhliso lwangoku.
