Isingeniso:
Ukushaja kwemizuzu emi-5 ngebanga lamakhilomitha angama-400! NgoMashi 17, i-BYD yakhipha uhlelo lwayo “lokushaja i-megawatt flash”, oluzokwenza izimoto zikagesi zikwazi ukushaja ngokushesha njengokugcwaliswa kukaphethiloli.
Kodwa-ke, ukuze kuzuzwe umgomo "kawoyela nogesi ngesivinini esifanayo", i-BYD ibonakala ifinyelele umkhawulo webhethri yayo ye-lithium iron phosphate. Naphezu kweqiniso lokuthi ukuminyana kwamandla we-lithium iron phosphate material ngokwayo kusondela emkhawulweni wayo wetiyetha, i-BYD isaphusha ukwakheka komkhiqizo nokwenza ngcono kobuchwepheshe ngokwedlulele.
Dlala ngokwedlulele! 10C lithium iron phosphate
Okokuqala, ngokolwazi olukhishwe esithangamini sabezindaba se-BYD, ubuchwepheshe bokushaja be-flash be-BYD busebenzisa umkhiqizo obizwa ngokuthi "ibhethri ye-flash yokushaja", okusewuhlobo lwebhethri ye-lithium iron phosphate.
Lokhu akuphuli nje kuphela ukubusa kwesilinganiso esiphakeme samabhethri e-lithium njengamabhethri e-nickel ternary aphezulu emakethe yokushaja okusheshayo, kodwa futhi kuvumela i-BYD ukuthi iphushe ukusebenza kwe-lithium iron phosphate ibe ngokwedlulele futhi, okuvumela i-BYD ukuthi iqhubeke nenani layo lemakethe kumzila wobuchwepheshe wamabhethri e-lithium iron phosphate.
Ngokusho kwedatha ekhishwe yi-BYD, i-BYD izuze amandla aphezulu okushaja angu-1 megawatt (1000 kW) kwamanye amamodeli afana ne-Han L ne-Tang L, futhi i-flash charge yemizuzu engu-5 ingangezelela ibanga elingamakhilomitha angu-400. 'Ibhethri' layo lokushaja 'ibhethri selifinyelele izinga lokushaja elingu-10C.
Imuphi umqondo lo? Ngokwezimiso zesayensi, okwamanje kuyaqashelwa embonini ukuthi ukuminyana kwamandla amabhethri e-lithium iron phosphate kuseduze nomkhawulo wethiyori. Ngokuvamile, ukuze kuqinisekiswe ukuminyana kwamandla okuphezulu, abakhiqizi bazodela okunye kokushaja kwabo kanye nokusebenza kokukhipha. Ngokuvamile, ukukhishwa kwe-3-5C kuthathwa njengesilinganiso esifanelekile sokukhipha amabhethri e-lithium iron phosphate.
Kodwa-ke, ngalesi sikhathi i-BYD ikhulise izinga lokukhishwa kwe-lithium iron phosphate kuya ku-10C, okusho ukuthi okwamanje cishe sekuphindwe kabili, kodwa futhi kusho ukuthi ukumelana kwangaphakathi nobunzima bokuphatha ukushisa kuphindwe kabili.
I-BYD ithi ngesisekelo se-blade, "ibhethri yokushaja i-flash" ye-BYD ithuthukisa isakhiwo se-electrode yebhethri ye-blade, inciphisa ukumelana nokufuduka kwe-lithium ion ngo-50%, ngaleyo ndlela ifinyelele izinga lokushaja elingaphezu kuka-10C okokuqala ngqa.
Entweni ye-electrode enhle, i-BYD isebenzisa ukuhlanzeka okuphezulu, ukucindezela okukhulu, kanye nesizukulwane sesine se-lithium iron phosphate materials, kanye nezinqubo zokuchotshozwa kwe-nanoscale, izithasiselo zefomula ezikhethekile, kanye nezinqubo zokubala ezishisa kakhulu. Isakhiwo sekristalu sangaphakathi esiphelele kakhulu kanye nendlela emfushane yokusabalalisa ye-lithium ion kwandisa izinga lokufuduka kwe-lithium ion, ngaleyo ndlela kunciphisa ukumelana kwangaphakathi kwebhethri futhi kuthuthukise ukusebenza kwezinga lokuphuma.
Ngaphezu kwalokho, mayelana nokukhethwa kwama-electrode angalungile nama-electrolyte, kuyadingeka futhi ukukhetha okuhle kakhulu kokuhle kakhulu. Ukusetshenziswa kwegraphite yokwenziwa enendawo ethize ephezulu kanye nokwengezwa kwama-electrolyte e-PEO (i-polyethylene oxide) asebenza kahle kakhulu sekubuye kwaba yizimo ezidingekayo zokusekela amabhethri e-lithium iron phosphate angu-10C.
Ngamafuphi, ukuze kuzuzwe impumelelo yokusebenza, i-BYD ayisebenzisi izindleko. Esithangamini nabezindaba, intengo ye-BYD Han L EV efakwe ibhethri "eshaja i-flash" isifinyelele ku-270000-350000 yuan, ecishe ibe ngama-yuan angu-70000 ngaphezu kwenani lenguqulo yayo yokushayela ehlakaniphile ye-2025 EV (imodeli ye-Honor engu-701KM).
Ingakanani impilo nokuphepha kwamabhethri ashaja i-flash?
Yiqiniso, ku-high-tech, ukubiza akuyona inkinga. Wonke umuntu usakhathazekile ngekhwalithi nokuphepha komkhiqizo.Mayelana nalokhu, u-Lian Yubo, iPhini Likamongameli Omkhulu we-BYD Group, uthe amabhethri ashaja i-flash angagcina impilo ende ngisho nalapho eshajwe ngamanani aphezulu kakhulu, ngokunyuka okungu-35% kumjikelezo webhethri.
Kungashiwo ukuthi impendulo ye-BYD kulokhu ilungile futhi igcwele amakhono, okungenani ayiwuphiki umthelela wokushajwa ngokweqile empilweni yebhethri.
Ngoba ngokomthetho, ukushaja okusheshayo nokushajwa kuzoba nemiphumela engenakuhlehliswa esakhiweni sebhethri. Ukushesha ukushaja nokukhipha isivinini, kuba mkhulu umthelela empilweni yomjikelezo webhethri. Ngokuphathelene nokushaja okukhulu, ukusetshenziswa kwesikhathi eside kuvame ukwehlisa impilo yebhethri ngo-20% ukuya ku-30%. Ngakho-ke, abakhiqizi abaningi batusa ukushaja ngokweqile njengendlela yokushaja okuphuthumayo.
Abanye abakhiqizi bazokwethula ukushajwa ngokweqile ngesisekelo sokuthuthukisa impilo yomjikelezo webhethri ngokwalo. Ukwehliswa kwempilo yebhethri okubangelwa ukushajwa ngokweqile kuxazululwa ukwanda kwempilo yebhethri komkhiqizi, okugcina kuvumele wonke umkhiqizo ukuthi ulondoloze ukushaja okuhle nokukhipha ukusebenza kahle phakathi neminyaka yawo yokuphila okulindelekile.
Ngaphezu kwalokho, ukuze kuzuzwe "ukushaja kwe-flash", i-BYD iphinde yasebenzisa uchungechunge lokuthuthukiswa kwesistimu mayelana nokushiyeka kwamabhethri e-lithium iron phosphate kanye nalo lonke uhlelo lokuhlinzeka ngogesi.
Ukuze kunxeshezelwe ukushiyeka kokusebenza kwezinga lokushisa eliphansi kumabhethri e-lithium iron phosphate, uhlelo lwe-BYD "lokushaja i-flash" lwethula idivayisi yokushisisa ukushaya kwenhliziyo ukuze kugcinwe ukushaja okusheshayo nokukhipha ukusebenza kwebhethri ngokuzifudumeza ngokwalo ezindaweni ezibandayo. Ngesikhathi esifanayo, ukuze ubhekane nokushisa kwebhethri okubangelwa ukushaja nokukhipha amandla aphezulu, indawo yebhethri ihlanganiswe nesistimu yokulawula izinga lokushisa lokupholisa uketshezi oluhlanganisiwe, olususa ngokuqondile ukushisa kwebhethri ngesiqandisi.
Mayelana nokusebenza kokuphepha, i-lithium iron phosphate iphinde yafakazela ukubaluleka kwayo. Ngokusho kwe-BYD, ibhethri layo elithi "flash charger" liphumelele kalula ukuhlolwa kokuchotshozwa kwamathani angu-1200 kanye nokuhlolwa kokushayisana kuka-70km/h. Isakhiwo samakhemikhali esizinzile kanye nezakhiwo zokubuyiswa komlilo ze-lithium iron phosphate ziphinde zinikeze isiqinisekiso esibaluleke kakhulu sokuphepha kwezimoto zikagesi.
Ibhekene nebhodlela lokushaja
Mhlawumbe abantu abaningi abanawo umqondo wamandla wezinga le-megawatt, kodwa kubalulekile ukuqonda ukuthi i-megawatt engu-1 ingase ibe amandla efektri ephakathi nendawo, umthamo ofakiwe wesikhungo esincane samandla elanga, noma ukusetshenziswa kukagesi komphakathi wabantu abayinkulungwane.
Yebo, ukuzwe kahle. Amandla okushaja emoto alingana nawemboni noma indawo yokuhlala. Isiteshi sokushaja kakhulu silingana nokusetshenziswa kukagesi kwesigamu somgwaqo. Lesi sikali sokusetshenziswa kukagesi sizoba yinselelo enkulu kugridi yamandla kagesi emadolobheni.
Akukhona ukuthi ayikho imali yokwakha iziteshi zokushaja, kodwa ukuze kwakhiwe iziteshi zokushaja ezinkulu, kuyadingeka ukulungisa yonke igridi kagesi yedolobha nomgwaqo. Njengokwenza amadombolo ikakhulukazi ipuleti likaviniga, le phrojekthi idinga umzamo omkhulu. Ngamandla ayo amanje, i-BYD ihlele kuphela ukwakhiwa “kweziteshi zokushaja ama-megawatt flash” ezingaphezu kuka-4000 ezweni lonke esikhathini esizayo.
4000 'iziteshi zokushaja ama-megawatt flash' azanele ngempela. Ukushaja kwe-Flash "amabhethri" kanye nokushaja kwe-flash "izimoto ziyisinyathelo sokuqala sokuzuza" uwoyela nogesi ngesivinini esifanayo ".
Ngokuthuthuka kwezimoto zikagesi kanye nobuchwepheshe bebhethri, inkinga yangempela isiqalile ukushintshela ekwakhiweni kwezikhungo zamandla kanye namanethiwekhi wamandla. Kokubili i-BYD ne-CATL, kanye nezinye izinkampani zebhethri nezimoto zikagesi e-China, zingase zibhekane namathuba amakhulu emakethe kulokhu.
