Abakhiqizi besiteshi sokushaja izimoto bathi: Uhlelo Lokushaja Oluphezulu lwe-800V

Abakhiqizi beziteshi zokushaja izimoto: Uhlelo lwe-800V olunamandla aphezulu kanye nokushaja okusheshayo kakhulu kwezimoto zikagesi kungafinyelela isikhathi sokushaja semizuzu eyi-10 kanye nobubanzi bamakhilomitha angama-300, okungaxazulula ngempumelelo ukukhathazeka kokugcwalisa kabusha, futhi kulindeleke ukuthi kube yindlela ejwayelekile yokushaja okusheshayo. Izinkampani zezimoto ezivamile zasekhaya nezakwamanye amazwe sezivele zenze izakhiwo ezifanele, futhi amamodeli amaningana angama-800V azokhiqizwa ngobuningi ngo-2022. Kodwa ahlonyiswe ngemoto yesikhulumi se-800V ephezulu yokushaja ekushajeni okuvamile kwenqwaba yokushaja, isivinini sokushaja asifikeleli kulokho okulindelwe, asikwazi ukufeza ukushaja okusheshayo okukhulu, ngakho-ke ukuphela kwenqwaba yeketanga lezimboni kudinga ukuthuthukiswa kanye nokuphela kwemoto, izingxenye eziningana zethrekhi zizozuza.

Okokuqala, kuyini ukushaja kwe-voltage ephezulu

Abakhiqizi beziteshi zokushaja izimoto: Ukushaja okusheshayo ukushaja okusheshayo, iyunithi yokulinganisa ingashaja izikhathi (C). Uma isiphindaphindi sokushaja sikhulu, isikhathi sokushaja siba sifushane.

Isiphindaphindi sokushaja (C) = ukushaja kwamanje (mA) / umthamo olinganiswe ngebhethri (mAh)

Isibonelo, uma umthamo webhethri ungu-4000mAh futhi amandla okushaja afinyelela ku-8000mAh, isiphindaphindi sokushaja singu-8000/4000 = 2C.

Abakhiqizi beziteshi zokushaja izimoto: Ukushaja okunesilinganiso esiphezulu akukhona okungu-0%-100% kwenkokhelo okwenziwa ngokushaja okunesilinganiso esiphezulu. Imodi yokushaja efanelekile ihlukaniswe ngezigaba ezintathu, isigaba 1: isimo sokushaja kusengaphambili; isigaba 2: ukushaja okunesilinganiso esiphezulu; isigaba 3: ukushaja okunesilinganiso esiphezulu.

Abakhiqizi beziteshi zokushaja izimoto: Isigaba 1 sokushaja kusengaphambili sidlala indima yokuvikela iseli yebhethri, isigaba 2 yilokho esikubiza ngokuthi isigaba sokushaja esinezinga eliphezulu, ububanzi bamandla ale nqubo buvame ukuba ku-20%-80%; isigaba 3 sokushaja i-voltage engaguquki kuhloswe ukukhawulela i-voltage, ukuvimbela iseli yebhethri ukuthi ingasebenzisi i-voltage ngokweqile, okungalimaza isakhiwo sebhethri.

1, Abakhiqizi beziteshi zokushaja izimoto: ukushaja okusheshayo kudinga ukuthuthukisa amandla okuphela kokushaja kanye ne-battery charge/discharge multiplier

Kunezindlela ezimbili eziyinhloko zokushaja ama-EV: ukushaja okusheshayo kwe-DC kanye nokushaja okuhamba kancane kwe-AC.

Abakhiqizi beziteshi zokushaja izimoto: Ukushaja kwe-AC okuhamba kancane kuhambisana nendawo yokushaja ekhaya noma ezindaweni zokupaka izimoto zomphakathi, amandla okushaja mancane kusukela kuma-kilowatts ambalwa kuya kuma-kilowatts amaningi, ngokuvamile kuthatha amahora angu-8-10 ukushaja ngokugcwele. Ukushaja kwe-AC okuhamba kancane kusebenzisa amandla e-AC angu-220V ngqo kusuka kugridi, futhi kuyiguqula ibe amandla e-DC nge-AC/DC converter ngaphakathi kweshaja ye-OBC engaphakathi ukuze inikeze ibhethri le-EV. Abakhiqizi beziteshi zokushaja izimoto: Ngenxa yamandla okushaja aphansi, amandla e-AC/DC converter eyakhelwe ku-OBC engaphakathi ngokuvamile aphansi, futhi izindleko ziphansi.

Abakhiqizi beziteshi zokushaja izimoto: Ukushaja okusheshayo kwe-DC ngokuvamile kuhambisana nezimo zokushaja emigwaqweni emikhulu/ohambweni olude, lapho amandla afinyelela amakhulu ama-kilowatts futhi kuthatha amahora angu-1-2 kuphela ukushaja ngokugcwele. Umongo wokushaja okusheshayo kwe-DC ukudlulisa i-AC/DC enamandla aphezulu eposini lokushaja okusheshayo, lapho iposi lokushaja le-DC liguqula amandla e-AC kusuka kugridi abe amandla e-DC anamandla aphezulu ngokusebenzisa i-rectifier ukuze ishaje ibhethri lemoto ngqo. Amandla aphezulu okushaja okusheshayo angafinyelela ku-350kW noma ngisho no-480kW, futhi isikhathi sokushaja okusheshayo kulindeleke ukuthi sehliswe sibe ngaphansi kwemizuzu engama-30, futhi esikhathini esizayo singacindezelwa sibe ngaphansi kwemizuzu eyishumi.
