Abavelisi bezikhululo zokutshaja iimoto:Ngenxa yenkqubela phambili eqhubekayo yetekhnoloji yebhetri kunye neenkampani zezithuthi kwiindawo ezilula nakwezinye iindawo zophuhliso, uluhlu lwezithuthi zombane luyaqhubeka nokuphucuka, uluhlu lweemodeli ezingaphezu kwe-1,000km luye lwatyhilwa enye emva kwenye, ixhala leemayile zezithuthi zombane ngokusisiseko liyancitshiswa, kodwa ukutshaja kuhamba kancinci, ukutshaja kunzima "ukulungisa ixhala lamandla" kusathintela uphuhliso lwezithuthi zombane. Itekhnoloji yokutshaja ekhoyo ifuna abathengi balinde imizuzu engama-40 okanye nangaphezulu ukuze bazalise, uhambo lweeholide "ukutshaja iyure, ukuhlala emgceni iiyure ezine" luye lwaba yingxaki enkulu kubanini bezithuthi ezintsha zamandla, ngoko ke ukugcwaliswa kombane ngokukhawuleza okulula njengokuzalisa kuye kwaba yindlela yemizamo yeshishini le-EV.
Abavelisi bezikhululo zokutshaja iimoto: Inkqubo ye-800V ephezulu yombane + ukutshaja ngokukhawuleza kakhulu kwezithuthi zombane kunokufikelela kwixesha lokutshaja lemizuzu eli-10 kunye nomgama weekhilomitha ezingama-300, nto leyo enokusombulula ngempumelelo ixhala lokuzalisa kwakhona, kwaye kulindeleke ukuba ibe yindlela ephambili yokutshaja ngokukhawuleza. Iinkampani zemoto zasekhaya nezangaphandle sele zenze uyilo olufanelekileyo, kwaye iimodeli ezininzi ze-800V ziya kuveliswa ngobuninzi ngo-2022. Kodwa zixhotyiswe nge-800V high-voltage car platform charging kwi-charging eqhelekileyo ye-charging pile, isantya sokutshaja asifikeleli kulindelo, asinakufikelela ekutshajeni ngokukhawuleza kakhulu, ngoko ke isiphelo se-pile se-industrial chain kufuneka siphuculwe kunye nesiphelo semoto, inani leenxalenye zendlela ziya kuzuza.
Okokuqala, yintoni ukutshaja kwe-voltage ephezulu
Abavelisi bezikhululo zokutshaja iimoto: Ukutshaja ngokukhawuleza kukutshaja ngokukhawuleza, iyunithi yokulinganisa inokutshaja amaxesha (C). Okukhona isiphindaphindi sokutshaja sikhulu, kokukhona ixesha lokutshaja lifutshane.
Isiphindaphindi sokutshaja (C) = umsinga wokutshaja (mA) / umthamo webhetri olinganiswe (mAh)
Umzekelo, ukuba umthamo webhetri yi-4000mAh kwaye umsinga wokutshaja ufikelela kwi-8000mAh, isixhobo sokutshaja yi-8000/4000 = 2C.
Abavelisi bezikhululo zokutshaja iimoto: Ukutshaja okunexabiso eliphezulu akuyonto i-0%-100% yentlawulo eyenziwa ngokutshaja okunexabiso eliphezulu. Indlela yokutshaja efanelekileyo yahlulwe yangamanqanaba amathathu, inqanaba loku-1: imeko yokutshaja kwangaphambili; inqanaba lesi-2: ukutshaja okunexabiso eliphezulu; inqanaba lesi-3: ukutshaja okunexabiso eliphezulu.
Abavelisi bezikhululo zokutshaja iimoto: Isigaba soku-1 sokutshaja kwangaphambili sidlala indima yokukhusela iseli yebhetri, isigaba sesi-2 yinto esiyibiza ngokuba yisigaba sokutshaja esinesantya esiphezulu, uluhlu lwamandla ale nkqubo ludla ngokuba kwi-20%-80%; isigaba sesi-3 sokutshaja i-voltage engaguqukiyo sijolise ekunciphiseni i-voltage, ukuthintela iseli yebhetri kwi-voltage engaphezulu, nto leyo enokonakalisa isakhiwo sebhetri.
1, Abavelisi bezikhululo zokutshaja iimoto: ukutshaja ngokukhawuleza kufuneka kuphuculwe amandla esiphelo sokutshaja kunye nesixhobo sokuphinda sitshaje/sokukhupha ibhetri
Kukho iindlela ezimbini eziphambili zokutshaja ii-EV: ukutshaja ngokukhawuleza kwe-DC kunye nokutshaja kancinci kwe-AC.
Abavelisi bezikhululo zokutshaja iimoto: Ukutshaja okucothayo kwe-AC kuhambelana nendawo yokutshaja ekhaya okanye kwiindawo zokupaka iimoto zoluntu, amandla okutshaja mancinci ukusuka kwii-kilowatts ezimbalwa ukuya kwii-kilowatts ezininzi, kudla ngokuthatha iiyure ezi-8-10 ukuze atshajwe ngokupheleleyo. Ukutshaja okucothayo kwe-AC kusebenzisa amandla e-220V AC ngqo kwigridi, kwaye kuyiguqula ibe ngamandla e-DC nge-AC/DC converter engaphakathi kwitshaja ye-OBC ekwibhodi ukuze inike ibhetri ye-EV. Abavelisi bezikhululo zokutshaja iimoto: Ngenxa yamandla okutshaja aphantsi, amandla e-AC/DC converter eyakhelwe kwi-OBC ekwibhodi ngokubanzi aphantsi, kwaye iindleko ziphantsi.
Abavelisi bezikhululo zokutshaja iimoto: Ukutshaja ngokukhawuleza kwe-DC ngokuqhelekileyo kuhambelana neemeko zokutshaja kwiindlela ezinkulu/uhambo olude, apho amandla afikelela kumakhulu ee-kilowatts kwaye kuthatha iiyure ezi-1-2 kuphela ukutshaja ngokupheleleyo. Eyona nto iphambili yokutshaja ngokukhawuleza kwe-DC kukudlulisela amandla aphezulu e-AC/DC kwisithuba sokutshaja ngokukhawuleza, apho isithuba sokutshaja se-DC siguqula amandla e-AC ukusuka kwigridi abe ngamandla aphezulu e-DC ngokusebenzisa isixhobo sokulungisa ukuze itshaje ibhetri yesithuthi ngokuthe ngqo. Amandla aphezulu okutshaja ngokukhawuleza anokufikelela kwi-350kW okanye i-480kW, kwaye ixesha lokutshaja ngokukhawuleza kulindeleke ukuba lincitshiswe libe ngaphantsi kwemizuzu engama-30, kwaye kwixesha elizayo linokunyanzeliswa libe ngaphantsi kwemizuzu elishumi.
Abavelisi bezikhululo zokutshaja iimoto:Isibhamu sokutshaja se-DC fast charging "yibhulorho" yenkqubo yokutshaja ngokukhawuleza ye-DC, eqhuba ukudluliselwa kunye nokuguqulwa kwamandla kunye nolwazi phakathi kwetshaja kunye nesithuthi. Isibhamu esiqhelekileyo sesizwe esipholileyo ngolwelo se-HUBER+SUHNER, i-RADOX® HPC 600, sinako ukufikelela ekutshajeni okuqhubekayo ukuya kuthi ga kwi-600A (ukuya kuthi ga kwi-800A ebomini bokwenyani), kunye nokusebenza kwe-600kW/1000V. I-RADOX® HPC 600 inikezela ngokutshaja okuqhubekayo kwe-600A (okulinganiswe ukuya kuthi ga kwi-800A), ukusebenza kwenkqubo kwe-600kW/1000V, inkqubo yokulinganisa elungele ukusetyenziswa, oonxibelelwano abanokutshintshwa ubomi benkonzo ende, ukhuseleko oluphezulu olune-IP67 rating, kunye ne-CCS1 kunye ne-CCS2 interfaces. Inokwenza ukutshaja ngokukhawuleza okusebenzayo nokulula, okunokugcina isantya esiphezulu sokutshaja, ukuqinisekisa ukhuseleko lokutshaja, ukunciphisa ubunzima bezixhobo kunye neendleko zokulungisa, kwaye lukhetho olungcono kwiindawo zokutshaja ezipholileyo ngolwelo.
Umfanekiso
2, Abavelisi bezikhululo zokutshaja iimoto: Phucula isantya sokutshaja esikhawulezayo: kufuneka uphucule amandla okuphela kokutshaja kunye nesiphindaphindi sokutshaja/ukukhupha ibhetri ngaxeshanye.
Amandla okutshaja asebenzayo lixabiso elincinci lamandla okutshaja kunye namandla okutshaja ebhetri, kwaye ukuphucula isantya sokutshaja esikhawulezayo, kuyimfuneko ukuphucula amandla okutshaja kunye nesantya sokutshaja/sokukhupha ibhetri ngaxeshanye.
Abavelisi bezikhululo zokutshaja iimoto:Amandla okutshaja (ifomula P=UI) anokwandiswa ngokonyusa i-voltage okanye i-current. Umzekelo, iPorsche Taycan yimodeli yokuqala yokubeka iqonga le-800V high-voltage, kwaye njengommeli oqhelekileyo wendlela ye-high-voltage, amandla ayo aphezulu okutshaja afikelele kwi-350kW.
Okwesibini, iingenelo kunye nokungalungi kokutshaja nge-high-voltage kunye nemeko yophuhliso lwangoku.
