Hlobo luni lwebhethri lamandla ezidingwa izimoto zikagesi? Lo mbuzo, ongabonakali udinga ukuphendulwa, usanda kuvuselela ukucabanga kwabantu ngenxa yesihloko esishisayo mayelana “nengxabano yezobuchwepheshe phakathi kwamabhethri e-lithium e-lithium kanye namabhethri e-lithium iron phosphate”.

Akukho ukungabaza mayelana “nokuphepha kuqala” nganoma yisiphi isikhathi. Kodwa-ke, njengoba sonke sazi, eminyakeni embalwa edlule, ngenxa yokuthi izinkampani eziningi ziye zawela ekuqhathaniseni okuyimpumputhe “kwebanga lokukhuthazela”, ukuzinza kwe-thermal akubi kakhulu, kodwa ibhethri ye-ternary lithium enamandla amakhulu kune-lithium iron phosphate. ibhethri lifunwa kakhulu. Ngakho-ke isithunzi sokuphepha semoto sikhokhe inani elinzima kakhulu.

Ngomhla zingama-29 kuNdasa, 2020, i-BYD yethula ngokusemthethweni ibhethri le-blade, imemezela ukuthi ibanga layo lokuhamba selifinyelele ezingeni elifanayo nebhethri ye-ternary lithium, futhi seliphumelele “ukuhlolwa kwe-acupuncture” embonini yebhethri yamandla. Ukuhlolwa kokuphepha kunzima njengokuqwala i-Everest.

Ikhiqizwa kanjani ibhethri le-blade elithembisa ukulichaza kabusha izinga elisha lokuphepha kwemoto kagesi?

Ngomhla zizi-4 kuJuni, umsebenzi oyimfihlo wefekthri onendikimba ethi “Climbing the Peak” wawubanjelwe efektri yaseChongqing yebhethri ye-Fordi. Ochwepheshe bemidiya abangaphezu kwe-100 nochwepheshe bemboni bavakashele isayithi. Imboni ephambili ngemuva kwebhethri ye-blade nayo yembulwa.

Ukuphishekela ngokweqile ukuminyana kwamandla, imboni yebhethri yamandla idinga ukulungiswa ngokushesha

Ngaphambi kokufika kwebhethri le-blade, inkinga yokuphepha kwebhethri bekuyinkinga ehlala isikhathi eside emhlabeni.

Ukuphepha kwebhethri lezimoto ezisebenza ngogesi ngokuvamile kubhekisela ekuphumeni okushisayo kwebhethri. Uma kuqhathaniswa namabhethri amabili ajwayelekile avame ukusetshenziswa ezimotweni zikagesi njengamanje, impahla ye-lithium iron phosphate ngokwayo inezinzuzo ezine ezinkulu zokukhishwa kokushisa okuphezulu kokuqala kokushisa, ukukhishwa kokushisa okuhamba kancane, ukukhiqizwa kokushisa okuncane, futhi impahla ayikhiphi umoya-mpilo ngesikhathi sokubola. inqubo futhi akulula ukubamba umlilo. Ukungaqini kahle kwe-thermal nokuphepha kwamabhethri e-ternary lithium kuyiqiniso elaziwa yimboni.

“Emazingeni okushisa angama-500 ° C, ukwakheka kwezinto ze-lithium iron phosphate zizinzile kakhulu, kodwa i-ternary lithium material izobola cishe ku-200 ° C, futhi ukusabela kwamakhemikhali kunobudlova kakhulu, kuzokhulula ama-molecule e-oksijini, futhi kulula ukubangela ukubaleka okushisayo.” USun Huajun, iphini lomphathi jikelele weDi Battery Company, uthe.

Kodwa-ke, nakuba mayelana nokuphepha, amabhethri e-lithium iron phosphate anezinzuzo ezingenakuqhathaniswa ngaphezu kwamabhethri e-lithium e-ternary, kodwa ngenxa yokuthi ukuminyana kwamandla kuphansi kunaleyo ye-ternary lithium, izinkampani eziningi zezimoto zabagibeli ziye zawela ekukhathazekeni okungenangqondo mayelana nokulingana kwamandla amabhethri amandla eminyakeni embalwa edlule. Ngokulandela, ibhethri ye-lithium iron phosphate lisahluliwe egagasini lokugcina lezingxabano zolayini nebhethri le-lithium le-ternary.

U-Wang Chuanfu, uSihlalo we-BYD Group, owaziwa ngokuthi “Inkosi Yebhethri”, waqala njengebhethri. Ngaphambi kokumenyezelwa kokukhiqizwa kwezimoto eziwela umngcele ngo-2003, ucwaningo nokuthuthukiswa kwamabhethri kagesi wezimoto kwase kuqalile. Kusukela kwethulwa ibhethri lamandla okuqala kuya ekubeni ngolunye lwezinhlobo zezimoto zamandla ezintsha ezinkulu kakhulu emhlabeni, i-BYD ihlezi ibeka “ukuphepha” kuqala ngokungaguquki.

Kusekelwe ngokuqondile ekubalulekeni okwedlulele kokuphepha ukuthi i-BYD ayikaze iyeke ukuthuthukiswa kabusha kwamabhethri e-lithium iron phosphate ngisho nasendaweni yemakethe lapho amabhethri e-ternary lithium aye ahlonishwa kakhulu eminyakeni embalwa edlule.

Ukuchaza kabusha izindinganiso zokuphepha, ukufaka isitembu “sokuhlolwa kwe-acupuncture”

Ibhethri ye-blade yazalwa, futhi imboni yaphawula ukuthi umzila wokuthuthukiswa wemboni yebhethri yamandla oye washiya ithrekhi iminyaka eminingi ekugcineni unethuba lokubuyela endleleni.

“Ukuphepha okuphezulu” isici esikhulu kunazo zonke sebhethri ye-blade. Mayelana nalokhu, ukuhlolwa kwe-acupuncture, okwaziwa ngokuthi “i-Mount Everest” emphakathini wokuhlola ukuphepha kwebhethri yamandla, kugxivizwe ngakho. Ngaphezu kwalokho, ibhethri ye-blade futhi inamandla amakhulu, impilo yebhethri ephezulu, izinga lokushisa eliphansi kakhulu, impilo ephezulu, amandla amakhulu nokusebenza okuphezulu kanye nomqondo wezobuchwepheshe “6S”.

Amabhethri angawodwa anobude obungama-96 cm, ububanzi obuyi-9 cm, nobude obungu-1.35 cm ahlelwe ngokulandelana futhi afakwe ephaketheni lebhethri njenge “blade”. Amamojula kanye nemishayo yeqiwa lapho kwakhiwa iqembu, elinciphisa Ngemuva kwezingxenye ezingafuneki, kwakhiwa isakhiwo esifana ne-honeycomb aluminium plate. Ngochungechunge lwezinqubo ezintsha zesakhiwo, ibhethri ye-blade ithole amandla amakhulu ebhethri, kuyilapho ukusebenza kokuphepha kwephakethe lebhethri kuye kwathuthukiswa kakhulu, futhi izinga lokusebenzisa ivolumu nalo lenyuke ngo-50%. ngenhla.

“Ngenxa yokuthi ibhethri ye-blade inganciphisa kakhulu izingxenye zesakhiwo ezengezwe yibhethri ye-lithium ye-ternary ngenxa yokuphepha kwebhethri okwanele namandla, ngaleyo ndlela yehlise isisindo semoto, ukuminyana kwethu kwamandla okukodwa akungaphezu kwalokho kwe-ternary lithium, kodwa kungafinyelela ibhethri ye-lithium evamile. Amabhethri e-lithium anokubekezela okufanayo. ” USun Huajun wembula.

“I-BYD Han EV yokuqala enamabhethri e-blade inohambo lokuhamba amakhilomitha angu-605 ngaphansi kwezimo zokusebenza eziphelele,” kusho uLi Yunfei, iphini lomphathi jikelele we-BYD Auto Sales.

Ngaphezu kwalokho, ibhethri ye-blade ingashaja ukusuka ku-10% iye ku-80% ngemizuzu engu-33, isekela ukusheshisa kwamakhilomitha angu-100 ngemizuzwana engu-3.9, ingahamba amakhilomitha ayizigidi ezingu-1.2 nemijikelezo engaphezu kuka-3000 yokushaja nokukhipha, kanye nokusebenza kwedatha okufana nokusebenza okuphansi kwezinga lokushisa elingaphezu kwamandla. umcabango wemboni. Ukuze kuzuzwe “inzuzo enkulu” yebhethri yayo yonke “rolling” ternary lithium.

Imboni enkulu ehumusha i-Industry 4.0, efihla imfihlo “yokuphakama phezulu” kwebhethri ye-blade

Ngomhla zingama-27 kuNhlaba, izindaba zokuthi amalungu angu-8 eqembu laseShayina agibele ngempumelelo iNtaba i-Everest zenza abantu baseShayina bajabule kakhulu, futhi ukweqa kwe-BYD kwenani elisha lokuphepha kwamabhethri nakho kuye kwavusa ukukhathazeka okusabalele nezingxoxo ezishisayo emkhakheni wezimoto zikagesi.

Kunzima kangakanani ukufika esiqongweni se-“Mount Everest” emhlabeni wokuphepha kwebhethri? Sivakashele ifekthri yakwaFudi Battery’s Chongqing futhi sathola izimpendulo.

Imboni yebhethri yakwa-Fudi esesifundeni sase-Bishan, e-Chongqing okwamanje ukuphela kwesizinda sokukhiqiza samabhethri e-blade. Imboni inotshalomali obuphelele obungama-yuan ayizigidi eziyizinkulungwane eziyi-10 kanye namandla okukhiqiza ahleliwe wonyaka angama-20GWH. Selokhu kwaqala ukwakhiwa ngoFebhuwari 2019 kanye nokwethulwa ngokusemthethweni kwebhethri ye-blade ngoMashi 2020, isishintshile isuka endaweni evulekile yaba imboni esezingeni lomhlaba enohlelo lokukhiqiza oluthambile, oluzenzakalelayo nolusekelwe olwazini ngonyaka owodwa nje. . Imigqa eminingi yokukhiqiza yebhethri yeblade ye-BYD kanye nezinto zokukhiqiza zazalelwa lapha, futhi inani lobuchwepheshe obuyimfihlo “lifihliwe”.

“Okokuqala, izidingo zendawo yokukhiqiza amabhethri e-blade zidinga kakhulu.” U-Sun Huajun uthe ukuze kuncishiswe izinga le-short-circuit lamabhethri, baphakamise umqondo wokulawula ukuhlukaniswa ngezigaba zothuli. Kwezinye izinqubo ezibalulekile, bangakwazi ukufeza isixazululo sokuma okukodwa. Esikhaleni samamitha, azikho izinhlayiya ezingaphezu kuka-29 zama-microns angu-5 (ubude bezinwele obungu-1/20 ukujiya), ezihlangabezana nezinga elifanayo neshabhu yokusebenzela yokukhiqiza isikrini se-LCD.

Imvelo enzima nezimo kuphela “isisekelo” sokuqinisekisa ukuphepha okuphezulu kwamabhethri e-blade. NgokukaSun Huajun, ubunzima obukhulu kanye nendawo ekhanyayo ekukhiqizeni amabhethri e-blade kugxile kakhulu “ezinqubweni ezinkulu eziyisishiyagalombili.”

“Isigxobo esinobude obucishe sibe imitha elingu-1 singafinyelela ukulawula ukubekezelelana ngaphakathi kuka-± 0.3mm kanye nokunemba nesivinini sokusebenza kahle kwe-single-piece lamination ku-0.3s/pcs. Singabokuqala emhlabeni. Le lamination yamukela i-BYD Imishini esungulwe ngokuzimela ngokuphelele kanye nohlelo lokusika alukwazi ukukopishwa yinoma ubani omunye ofuna ukukopisha.” Kusho uSun Huajun.

Ngaphezu kwe-lamination, i-batching, i-coating, rolling, ukuhlolwa nezinye izinqubo zenqubo yokukhiqiza ibhethri ye-blade ifinyelele ezingeni eliphezulu emhlabeni. Isibonelo, ukunemba kwesistimu yokuhlanganisa kungaphakathi kwe-0.2%; izinhlangothi zombili ziboshwe ngasikhathi sinye, ububanzi be-coating ububanzi buyi-1300mm, futhi ukuchezuka kwesisindo sokugqoka endaweni ngayinye kungaphansi kwe-1%; ijubane eligoqayo lika-1200mm ultra-wide wide lingafinyelela ku-120m/min, futhi ukujiya kulawulwa. Ngaphakathi kuka-2μm, ukuqinisekisa ukuvumelana kogqinsi lwesiqeshana sosayizi obanzi ……

Lonke ibhethri le-blade lizalwa ekuphishekeleni okungapheli kokuphelela! Eqinisweni, ubuciko nezinqubo ezifana “nokwengeza okungcono kakhulu” zisuka ohlelweni lokukhiqiza nokuphatha lwezinga le-4.0 lwemboni yebhethri ye-blade.

Izinzwa ezinemba okuphezulu kuzo zonke izinkundla zokusebenzela zokukhiqiza, izinqubo, nemigqa, amakhulukhulu amarobhothi, kanye nesistimu yokulawula ikhwalithi ehlangabezana nezinga lokulawula le-IATF16949&VDA6.3, njll., inika amandla ukuzenzekela kwehadiwe yemishini yezitshalo kanye nolwazi lwesisetshenziswa namathuluzi. Ubuhlakani bezinga lokulawula sebuphenduke “ukusekelwa” okuqine kakhulu kwekhwalithi esebenza kahle futhi ezinzile yokukhiqizwa kwebhethri ye-blade.

“Eqinisweni, umkhiqizo wethu ngamunye webhethri le-blade nawo unekhadi le-‘ID’ elikhethekile. Ngokuzayo, imininingwane ehlukahlukene ngesikhathi sokusetshenziswa komkhiqizo izophinde isinikeze ireferensi ebalulekile yokuthuthukisa okuqhubekayo kwenqubo nomkhiqizo ophelele. ” U-Sun Huajun uthe, imboni ye-Ford Battery Chongqing iyimboni yokuqala kuphela emhlabeni yamabhethri e-blade. Ngokukhula okuqhubekayo komthamo wokukhiqiza, amabhethri e-blade azovuleleka kuyo yonke imboni yezimoto zamandla amasha ukuze kwabelwane, kuzuzise imboni kanye nabathengi, nokusiza ukuthuthukiswa kwezimoto zikagesi zomhlaba wonke zingene enkathini entsha.

“Namuhla, cishe zonke izinhlobo zezimoto ongazicabanga zixoxa nathi ngezinhlelo zokubambisana ezisekelwe kubuchwepheshe bebhethri ye-blade.” Uthe.

Futhi namuhla sithuthukise iphakethe lebhethri lamasosha akwa-E, ama-E yatch, izikebhe ze-E……
