Isingeniso：
Ukushaja kwemizuzu emi-5 ngebanga elingamakhilomitha angu-400! Ngomhlaka-17 Mashi, i-BYD ikhiphe uhlelo lwayo "lokushaja nge-megawatt flash", oluzokwenza izimoto zikagesi zikwazi ukushaja ngokushesha njengokugcwalisa uphethiloli.
Kodwa-ke, ukuze kufezwe umgomo "wokoyela nogesi ngesivinini esifanayo", kubonakala sengathi i-BYD ifinyelele umkhawulo webhethri layo le-lithium iron phosphate. Naphezu kokuthi ubukhulu bamandla bezinto ze-lithium iron phosphate ngokwayo busondela emkhawulweni wazo wethiyori, i-BYD isaqhubekisela phambili ukuklama umkhiqizo kanye nokwenza ngcono ubuchwepheshe kakhulu.
Dlala kakhulu! I-10C lithium iron phosphate
Okokuqala, ngokusho kolwazi olukhishwe engqungqutheleni yabezindaba ye-BYD, ubuchwepheshe bokushaja nge-flash be-BYD busebenzisa umkhiqizo obizwa ngokuthi "ibhethri le-flash charging blade", okusewuhlobo lwebhethri le-lithium iron phosphate.
Lokhu akugcini nje ngokuphula ukubusa kwamabhethri e-lithium anezinga eliphezulu njengamabhethri e-nickel ternary aphezulu emakethe yokushaja okusheshayo, kodwa futhi kuvumela i-BYD ukuthi iphinde iqhubekisele phambili ukusebenza kwe-lithium iron phosphate, okuvumela i-BYD ukuthi iqhubeke nenani layo lemakethe endleleni yobuchwepheshe yamabhethri e-lithium iron phosphate.
Ngokusho kwedatha ekhishwe yi-BYD, i-BYD ifinyelele amandla okushaja aphezulu angu-1 megawatt (1000 kW) kwamanye amamodeli afana ne-Han L ne-Tang L, futhi ukushaja kwe-flash kwemizuzu emi-5 kungangeza ibanga elingamakhilomitha angu-400. Ibhethri layo lokushaja kwe-flash lifinyelele izinga lokushaja elingu-10C.
Yimuphi lo mqondo? Ngokwezimiso zesayensi, okwamanje kuyaziwa embonini ukuthi ubuningi bamandla bamabhethri e-lithium iron phosphate buseduze nomkhawulo wethiyori. Ngokuvamile, ukuze kuqinisekiswe ubuningi bamandla aphezulu, abakhiqizi bazodela ukusebenza kwabo kokushaja nokukhipha. Ngokuvamile, ukukhishwa okungu-3-5C kubhekwa njengesilinganiso esifanele sokukhishwa kwamabhethri e-lithium iron phosphate.
Kodwa-ke, kulokhu i-BYD inyuse izinga lokukhishwa kwe-lithium iron phosphate laya ku-10C, okungasho nje kuphela ukuthi ugesi usucishe waphindeka kabili, kodwa futhi kusho ukuthi ukumelana kwangaphakathi kanye nobunzima bokuphathwa kokushisa sekuphindeke kabili.
I-BYD ithi ngokusekelwe ku-blade, "ibhethri lokushaja nge-flash" le-BYD lenza ngcono isakhiwo se-electrode sebhethri le-blade, linciphise ukumelana kokufuduka kwama-ion e-lithium ngo-50%, ngaleyo ndlela lifinyelele izinga lokushaja elingaphezu kuka-10C okokuqala.
Kwizinto ezibonakalayo ze-electrode, i-BYD isebenzisa izinto ze-lithium iron phosphate zesizukulwane sesine ezihlanzekile kakhulu, ezicindezela kakhulu, kanye nezinobukhulu obukhulu, kanye nezinqubo zokuchoboza ze-nanoscale, izithasiselo ezikhethekile zefomula, kanye nezinqubo zokubala ezishisa kakhulu. Isakhiwo sekristalu sangaphakathi esiphelele kanye nendlela emfushane yokusabalalisa yama-ion e-lithium kwandisa izinga lokufuduka kwama-ion e-lithium, ngaleyo ndlela kunciphisa ukumelana kwangaphakathi kwebhethri futhi kuthuthukise ukusebenza kwesilinganiso sokukhishwa.
Ngaphezu kwalokho, maqondana nokukhethwa kwama-electrode nama-electrolyte angalungile, kuyadingeka futhi ukukhetha okungcono kakhulu kwangcono kakhulu. Ukusetshenziswa kwe-graphite yokwenziwa enendawo ephezulu yobuso kanye nokwengezwa kwama-electrolyte e-PEO (polyethylene oxide) asebenza kahle nakho kube yizimo ezidingekayo ukusekela amabhethri e-10C lithium iron phosphate.
Ngamafuphi, ukuze kufezwe impumelelo yokusebenza, i-BYD ayichithi mali. Esithangamini nabezindaba, intengo ye-BYD Han L EV efakwe ibhethri "lokushaja i-flash" ifinyelele ku-270000-350000 yuan, okucishe kube yi-70000 yuan ephezulu kunentengo yenguqulo yayo yokushayela ehlakaniphile ye-EV ka-2025 (imodeli ye-701KM Honor).
Iyini impilo kanye nokuphepha kwamabhethri okushaja nge-flash?
Vele, kobuchwepheshe obuphezulu, ukubiza kakhulu akuyona inkinga. Wonke umuntu usakhathazekile ngekhwalithi nokuphepha komkhiqizo. Mayelana nalokhu, uLian Yubo, iPhini likaMongameli oPhethe we-BYD Group, uthe amabhethri okushaja nge-flash angahlala isikhathi eside ngisho noma eshajwa ngamanani aphezulu kakhulu, kanye nokwenyuka okungu-35% kwempilo yomjikelezo webhethri.
Kungashiwo ukuthi impendulo ye-BYD kulokhu ilungile futhi igcwele amakhono, okungenani ingakuphiki umthelela wokushaja ngokweqile empilweni yebhethri.
Ngoba ngokomthetho, ukushaja nokukhipha ngokushesha kuzoba nemiphumela engenakuguqulwa esakhiweni sebhethri. Uma isivinini sokushaja nokukhipha sishesha, kulapho umthelela omkhulu empilweni yomjikelezo webhethri. Ngokuphathelene nokushaja kakhulu, ukusetshenziswa kwesikhathi eside kuvame ukunciphisa impilo yebhethri ngo-20% kuya ku-30%. Ngakho-ke, abakhiqizi abaningi batusa ukushaja ngokweqile njengendlela yokushaja ephuthumayo.
Abanye abakhiqizi bazofaka ukushaja ngokweqile ngesisekelo sokuthuthukisa impilo yomjikelezo webhethri uqobo. Ukuncipha kwempilo yebhethri okubangelwa ukushaja ngokweqile kuncishiswa ukwanda kwempilo yebhethri ngumkhiqizi, ekugcineni okuvumela wonke umkhiqizo ukuthi ulondoloze ukusebenza kahle kokushaja nokukhipha amandla ngaphakathi kwesikhathi sawo sokuphila esilindelekile.
Ngaphezu kwalokho, ukuze kufezwe "ukushaja kwe-flash", i-BYD iphinde yaqalisa uchungechunge lokuthuthukiswa kwesistimu mayelana nokushiyeka kwamabhethri e-lithium iron phosphate kanye nalo lonke uhlelo lokuphakelwa kwamandla.
Ukuze kulungiswe amaphutha okusebenza kwezinga lokushisa eliphansi kumabhethri e-lithium iron phosphate, uhlelo lwe-BYD "lokushaja nge-flash" luveza idivayisi yokushisa ye-pulse ukuze kugcinwe ukusebenza kokushaja nokukhipha ibhethri ngokushesha ngokuzifudumeza ezindaweni ezibandayo. Ngesikhathi esifanayo, ukuze kuhlangatshezwane nokushisa kwebhethri okubangelwa ukushaja nokukhipha amandla aphezulu, indawo yebhethri ihlanganiswe nohlelo lokulawula izinga lokushisa lokupholisa oluhlanganisiwe, olususa ngqo ukushisa kwebhethri ngesiqandisi.
Ngokuphathelene nokusebenza kokuphepha, i-lithium iron phosphate iphinde yafakazela inani layo. Ngokusho kwe-BYD, ibhethri layo le-"flash charging" lidlule kalula ekuhlolweni kokuchotshozwa kwamathani angu-1200 kanye nokuhlolwa kokushayisana kwamakhilomitha angu-70/h. Isakhiwo samakhemikhali esizinzile kanye nezakhiwo ezivimbela ilangabi ze-lithium iron phosphate ziphinde zinikeze isiqinisekiso esiyisisekelo sokuphepha kwezimoto zikagesi.
Ukubhekana ne-bottleneck yokushaja
Mhlawumbe abantu abaningi abanawo umqondo wamandla asezingeni le-megawatt, kodwa kubalulekile ukuqonda ukuthi i-megawatt eyodwa ingaba amandla efektri ephakathi nendawo, amandla afakiwe esitshalo esincane samandla elanga, noma ukusetshenziswa kukagesi komphakathi wabantu abayinkulungwane.
Yebo, ukuzwile kahle. Amandla okushaja emoto alingana nalawo efektri noma indawo yokuhlala. Isiteshi sokushaja esinogesi ongaphezulu silingana nokusetshenziswa kukagesi kwengxenye yomgwaqo. Lesi silinganiso sokusetshenziswa kukagesi sizoba yinselele enkulu kugridi kagesi yasemadolobheni yamanje.
Akukhona ukuthi ayikho imali yokwakha iziteshi zokushaja, kodwa ukwakha iziteshi zokushaja kakhulu, kuyadingeka ukuvuselela igridi kagesi yedolobha lonke kanye neyomgwaqo. Njengokwenza ama-dumplings ngqo epuletini likaviniga, lo msebenzi udinga umzamo omkhulu. Ngamandla ayo amanje, i-BYD ihlele kuphela ukwakhiwa kweziteshi zokushaja ze-flash "megawatt" ezingaphezu kuka-4000 ezweni lonke esikhathini esizayo.
Iziteshi zokushaja i-flash ezingama-megawatt angu-4000 empeleni azanele. "Amabhethri kanye" nezimoto zokushaja i-flash kuyisinyathelo sokuqala sokufinyelela "uwoyela nogesi ngesivinini esifanayo".
Ngokuthuthuka kwezobuchwepheshe bezimoto zikagesi kanye nebhethri, inkinga yangempela isiqalile ukushintshela ekwakhiweni kwezikhungo zikagesi kanye namanethiwekhi kagesi. Zombili i-BYD kanye ne-CATL, kanye nezinye izinkampani zezimoto zamabhethri kanye nezimoto zikagesi eShayina, zingase zibhekane namathuba amakhulu emakethe kulokhu.
