Loluphi uhlobo lwebhetri yamandla ezifunwa zizithuthi zombane? Lo mbuzo, obonakala ungafuneki ukuba uphendulwe, kutshanje uye walawula ukucinga kwabantu ngenxa yesihloko esishushu malunga “nengxabano yezobuchwepheshe phakathi kweebhetri ze-lithium ze-lithium kunye neebhetri ze-lithium iron phosphate”.

Akukho mathandabuzo “ngokhuseleko kuqala” nangaliphi na ixesha. Nangona kunjalo, njengoko sonke sisazi, kwiminyaka embalwa edlulileyo, ngenxa yokuba iinkampani ezininzi ziye zawela kuthelekiso oluyimfama “loluhlu lonyamezelo”, uzinzo lwe-thermal lwendalo luhlwempuzekileyo, kodwa ibhetri ye-lithium ye-ternary enoxinano lwamandla aphezulu kune-lithium iron phosphate. ibhetri ifunwa ngokubanzi emva. Isidima sokhuseleko lwemoto ke ngoko sihlawule ixabiso elinzima kakhulu.

Ngomhla wama-29 kuMatshi ka-2020, i-BYD yazisa ngokusesikweni ibhetri yeblade, ibhengeza ukuba uluhlu lwayo lokuhamba ngenqanawa lufikelele kwinqanaba elifanayo nebhetri ye-lithium ye-ternary, kwaye iphumelele “uvavanyo lwe-acupuncture” olunzima kwishishini lebhetri yamandla. Uvavanyo lokhuseleko lunzima njengokukhwela i-Everest.

Iveliswa njani ibhetri yeblade eyenza isibhambathiso sokuchaza umgangatho omtsha wokhuseleko lwesithuthi sombane?

Ngomhla we-4 kaJuni, umsebenzi oyimfihlo wefektri onomxholo othi “Ukunyuka kwePeak” wawubanjelwe kumzi-mveliso waseChongqing weFordi Battery. Ngaphezulu kwe-100 leengcali zosasazo kunye neengcali zemizi-mveliso zatyelela indawo. Umzi-mveliso omkhulu emva kwebhetri ye-blade nawo watyhilwa.

Ukusukela ngokugqithisileyo uxinano lwamandla, ishishini lebhetri lamandla lifuna ukulungiswa ngokukhawuleza

Ngaphambi kokufika kwebhetri ye-blade, ingxaki yokhuseleko lwebhetri ibe yinto ekudala ikho emhlabeni.

Ukhuseleko lwebhetri lwezithuthi zombane lubhekiselele ekubalekeni kwebhetri ngokushushu. Xa kuthelekiswa neebhetri ezimbini eziqhelekileyo eziqhelekileyo ezisetyenziswa kwizithuthi zombane okwangoku, i-lithium iron phosphate impahla ngokwayo ineenzuzo ezine ezinkulu zokukhutshwa kobushushu obuphezulu, ukukhutshwa kobushushu obucothayo, ukuveliswa kobushushu obuncinci, kwaye izinto aziyikhuphi ioksijini ngexesha lokubola. inkqubo kwaye akukho lula ukubamba umlilo. Uzinzo olubi lwe-thermal kunye nokhuseleko lweebhetri ze-lithium ze-ternary yinyani eyaziwayo kwishishini.

Kwiqondo lokushisa kwe-500 ° C, isakhiwo sezinto ze-lithium iron phosphate sizinzile kakhulu, kodwa i-ternary lithium iya kubola malunga ne-200 ° C, kwaye ukusabela kweekhemikhali kunobundlobongela ngakumbi, kuya kukhulula i-oksijeni i-oksijeni, kwaye kulula ukubangela ukubaleka kwe-thermal.” USun Huajun, usekela mphathi jikelele weDi Battery Company, uthe.

Nangona kunjalo, nangona ngokwemiqathango yokhuseleko, iibhetri ze-lithium iron phosphate zineengenelo ezingenakuthelekiswa nanto kwiibhetri ze-ternary lithium, kodwa ngenxa yokuba uxinano lwamandla lungaphantsi kune-ternary lithium, iinkampani ezininzi zeemoto zabahambi ziye zawela kwiinkxalabo ezingenangqondo malunga nokuxinana kwamandla ebhetri kwiminyaka embalwa edlulileyo. Ukuqhubela phambili, ibhetri ye-lithium ye-iron phosphate yayisahluliwe kwi-wave yokugqibela yeengxabano zomgca kunye ne-ternary lithium ibhetri.

UWang Chuanfu, uSihlalo weQela le-BYD, owaziwa ngokuba yi “Battery King”, waqala njengebhetri. Ngaphambi kokubhengezwa kwemveliso ye-cross-border yeemoto kwi-2003, uphando kunye nophuhliso lweebhetri zamandla eemoto sele ziqalile. Ukusukela ekusungulweni kwebhetri yokuqala yamandla ukuya ekubeni lelinye lawona magama makhulu ehlabathini, i-BYD ibisoloko ibeka “ukhuseleko” kwindawo yokuqala ngokungagungqiyo.

Isekwe ngokuthe ngqo kukubaluleka okugqithisileyo kokhuseleko ukuba i-BYD ayizange inikezele ukuphuhliswa kwakhona kweebhetri ze-lithium iron phosphate nakwimeko yemarike apho iibhetri ze-ternary lithium ziye zahlonitshwa ngokubanzi kwiminyaka embalwa edlulileyo.

Ukuchaza kwakhona imigangatho yokhuseleko, isitampu “uvavanyo lwe-acupuncture”

Ibhetri ye-blade yazalwa, kwaye imboni yaphawula ukuba indlela yokuphuhlisa imboni yebhetri yamandla esele iphelile iminyaka emininzi ekugqibeleni inethuba lokubuyela kwindlela.

“Ukhuseleko oluphezulu” luphawu olukhulu lwebhetri yeblade. Kule nkalo, uvavanyo lwe-acupuncture, olubizwa ngokuba yi “Mount Everest” kuluntu lokuvavanya ukhuseleko lwebhetri, lufakwe isitampu kuyo. Ukongeza, ibhetri ye-blade inamandla amakhulu, ubomi bebhetri obuphezulu, ubushushu obuphantsi kakhulu, ubomi obuphezulu, amandla amakhulu kunye nokusebenza okuphezulu kunye nengcamango yezobugcisa “6S”.

Iibhetri ezilodwa ezinobude be-96 cm, ububanzi be-9 cm, kunye nobude be-1.35 cm zicwangciswe ngokulandelelana kwaye zifakwe kwi-pack ibhetri njenge “blade”. Iimodyuli kunye nemiqadi igqithwa xa kusenziwa iqela, elinciphisa Emva kweengxenye ezingafunekiyo, isakhiwo esifana ne-honeycomb aluminium plate yenziwe. Ngokusebenzisa uthotho lwezinto ezintsha zesakhiwo, ibhetri ye-blade ifumene amandla amakhulu ebhetri, ngelixa ukusebenza kokhuseleko lwebhetri kuphuculwe kakhulu, kwaye izinga lokusetyenziswa kwevolumu liye landa nge-50%. ngaphezulu.

“Ngenxa yokuba ibhetri yeblade inokunciphisa kakhulu iindawo ezidityanisiweyo zongezwa yi-ternary lithium ibhetri ngenxa yokungakhuseleki ngokwaneleyo kwebhetri kunye namandla, ngaloo ndlela inciphisa ubunzima besithuthi, amandla ethu ombane omnye abukho ngaphezu kwe-lithium ye-ternary, kodwa inokufikelela. ibhetri ye-lithium eqhelekileyo. Iibhetri zeLithium zinonyamezelo olufanayo. ” U-Sun Huajun utyhile.

“I-BYD Han EV yokuqala ifakwe iibhetri ze-blade inoluhlu lokuhamba ngeekhilomitha ezingama-605 phantsi kweemeko ezibanzi zokusebenza,” utshilo uLi Yunfei, usekela-mphathi jikelele we-BYD Auto Sales.

Ukongeza, ibhetri ye-blade inokuhlawula ukusuka kwi-10% ukuya kwi-80% kwimizuzu ye-33, isekela i-100 yeekhilomitha ukukhawulezisa imizuzwana ye-3.9, inokuhamba ngeekhilomitha ze-1.2 yezigidi kunye nemijikelezo engaphezu kwe-3000 yokutshaja kunye nokukhupha, kunye nokusebenza kwedatha efana nokusebenza kweqondo lokushisa eliphantsi ngaphaya. ingcinga yoshishino. Ukuze kuphunyezwe “inzuzo super” yayo yonke-round “rolling” ternary lithium ibhetri.

Umzi-mveliso omkhulu otolika i-Industry 4.0, efihla imfihlo “yencopho ukuya phezulu” yebhetri yeblade

NgoMeyi 27, iindaba ezithi 8 amalungu eqela Chinese wakhwela ngempumelelo Mount Everest wenza abantu Chinese bazive bechulumancile kakhulu, kwaye BYD kaThixo ukutsiba incopho entsha kukhuseleko ibhetri kwakhona kwavusa inkxalabo ngokubanzi kunye neengxoxo ezishushu kwibala izithuthi zombane.

Kunzima kangakanani ukufikelela encotsheni ye “Mount Everest” kwihlabathi lokhuseleko lwebhetri? Sityelele umzi-mveliso weFudi Bettery’s Chongqing kwaye safumana iimpendulo.

Umzi-mveliso webhetri iFudi kwiSithili saseBishan, iChongqing ngoku kuphela kwesiseko semveliso yeebhetri zeblade. Umzi-mveliso unotyalo-mali olupheleleyo lwe-10 yeebhiliyoni zeeyuan kunye nomthamo ocetyiweyo wonyaka wemveliso we-20GWH. Ukusukela oko kwaqalwa ukwakhiwa ngoFebruwari ka-2019 kunye nokuphehlelelwa ngokusemthethweni kwebhetri yeblade ngoMatshi ka-2020, itshintshile isuka kwindawo evulekileyo yaba ngumzi mveliso okumgangatho wehlabathi onenkqubo yolawulo yokuvelisa ebhityileyo, ezenzekelayo, kunye nesekwe kulwazi kunyaka nje omnye. . Uninzi lwemigca yokuvelisa ibhetri yeBYD yoqobo kunye nezixhobo zokuvelisa zazalelwa apha, kwaye uninzi lobugcisa obuyimfihlo “bufihliwe”.

“Okokuqala, iimfuno zendawo yokuvelisa iibhetri zeblade zinzima kakhulu.” U-Sun Huajun uthe ukuze kuncitshiswe izinga leebhetri ezimfutshane, bacebise ingqikelelo yolawulo lokuhlela uthuli. Kwezinye iinkqubo eziphambili, banokufikelela kwisisombululo esisodwa. Kwisithuba semitha, akukho zincinci ze-29 ze-microns ze-5 (ubude beenwele 1/20 ubukhulu), obuhlangabezana nomgangatho ofanayo kunye ne-workshop yokuvelisa isikrini se-LCD.

Indawo engqongileyo kunye neemeko kuphela “isiseko” sokuqinisekisa ukhuseleko oluphezulu lweebhetri ze-blade. Ngokuka-Sun Huajun, obona bunzima bukhulu kunye nendawo eqaqambileyo ekuvelisweni kweebhetri zeblade zigxile ikakhulu “kwiinkqubo ezinkulu ezisibhozo.”

Isiqwenga sepali esinobude obuphantse bube imitha ye-1 sinokufikelela kulawulo lokunyamezela ngaphakathi kwe-± 0.3mm kunye nokuchaneka kunye nesantya se-single-piece lamination esebenzayo kwi-0.3s / pcs. Singabokuqala emhlabeni. Le lamination yamkela i-BYD Isixhobo esiphuhliswe ngokuzimeleyo ngokupheleleyo kunye nesicwangciso sokusika asinakukhutshelwa nguye nabani na ofuna ukukopa. USun Huajun uthe.

Ukongeza kwi-lamination, i-batching, i-coating, i-rolling, ukuvavanya kunye nezinye iinkqubo kwinkqubo yokuvelisa ibhetri ye-blade ifikelele kumgangatho ophezulu wehlabathi. Ngokomzekelo, ukuchaneka kwenkqubo yokudibanisa kungaphakathi kwe-0.2%; macala omabini agqunywe ngaxeshanye, ubuninzi bokugquma ububanzi buyi-1300mm, kwaye ukutenxa ubunzima bokutyhala kwindawo nganye yeyunithi ingaphantsi kwe-1%; isantya sokuqengqeleka kwe-1200mm ultra-wide wide inokufikelela kwi-120m / min, kwaye ubukhulu bulawulwa. Ngaphakathi kwe-2μm, ukuqinisekisa ukuhambelana kobukhulu beqhekeza lepali elinobungakanani obubanzi……

Yonke ibhetri yeblade izalwa ekusukeleni okungapheliyo kokugqibelela! Ngapha koko, ubugcisa kunye neenkqubo ezinje “ukugqwesa okona kulungileyo” zisuka kushishino lwenqanaba le-4.0 lokuvelisa kunye nenkqubo yolawulo yomzi mveliso webhetri yeblade.

Izinzwa ezichanekileyo kuzo zonke iindibano zocweyo zemveliso, iinkqubo, kunye nemigca, amakhulu eerobhothi, kunye nenkqubo yolawulo lomgangatho edibana nomgangatho wolawulo we-IATF16949&VDA6.3, njl.njl., yenza ukuba ukuzenzekelayo kwezixhobo zezixhobo zezityalo kunye nolwazi lwezixhobo kunye nezixhobo. Ubukrelekrele benqanaba lolawulo lube yeyona “backing” inamandla kumgangatho osebenzayo kunye nozinzile wemveliso yebhetri yeblade.

“Enyanisweni, imveliso nganye yebhetri yeblade nayo inekhadi le-ID elikhethekileyo. Kwixesha elizayo, idatha eyahlukeneyo ngexesha lokusetyenziswa kwemveliso iya kusinika ireferensi ebalulekileyo yokuphucula inkqubo kunye nemveliso egqibeleleyo. ” USun Huajun uthe, iFord Battery Chongqing plant yifektri yokuqala yehlabathi yeebhetri zeblade. Ngokunyuka okuqhubekayo komthamo wokuvelisa, iibhetri ze-blade ziya kuvuleleka kulo lonke ishishini elitsha lezithuthi zamandla okwabelana, ukuxhamla kwishishini kunye nabathengi, kunye nokunceda ukuphuhliswa kwezithuthi zombane zehlabathi zingene kwixesha elitsha.

“Namhlanje, phantse zonke iimoto onokucinga ngazo zixoxa ngezicwangciso zentsebenziswano ezisekwe kwitekhnoloji yebhetri yeblade kunye nathi.” Uthe.

Kwaye namhlanje siye saphuhlisa ipakethi yebhetri yeenqanawa ze-E, iiyatshi ze-E, izikhephe ze-E……
