Hapana mubvunzo nezve “kuchengetedzwa kwekutanga” chero nguva. Nekudaro, sezvatinoziva tese, mumakore mashoma apfuura, nekuti makambani mazhinji akawira muupofu kuenzanisa kwe “endurance range”, inherent thermal kugadzikana kwakashata, asi ternary lithium bhatiri ine yakakwirira simba density kupfuura lithium iron phosphate. bhatiri rinotsvakwa zvakanyanya. Mukurumbira wekuchengetedza motokari nekudaro wakabhadhara mutengo unorema zvakanyanya.

 

Musi waKurume 29, 2020, BYD yakaparura zviri pamutemo bhatiri reblade, ichizivisa kuti rwendo rwayo rwasvika padanho rakafanana neiyo ternary lithium bhatiri, uye yapfuura iyo inotyisa “acupuncture test” muindasitiri yemagetsi bhatiri. Muedzo wekuchengeteka wakaoma sekukwira Everest.

Iyo blade bhatiri inopika kutsanangura patsva chiyero chekuchengetedza mota yemagetsi inogadzirwa sei?

Musi wa4 Chikumi, chiitiko chakavanzika chefekitori chine dingindira rekuti “Kukwira Peak” chakaitwa paChongqing fekitori yeFordi Battery. Vanopfuura zana vezvenhau nenyanzvi dzeindasitiri vakashanyira saiti. Fekitori yepamusoro kuseri kwebhatiri reblade yakavhurwawo.

Kunyanya kutsvaga kwesimba density, iyo magetsi bhatiri indasitiri inoda kururamiswa nekukurumidza

Kusati kwauya bhatiri reblade, dambudziko rekuchengetedza bhatiri rave nyaya yakagara kwenguva refu munyika.

Kuchengetedzeka kwebhatiri remotokari dzemagetsi kunowanzo reva kudziya kwebhatiri. Kuenzaniswa nemabhatiri maviri akajairika anowanzoshandiswa mumotokari dzemagetsi pari zvino, iyo lithium iron phosphate zvinhu pachayo ine mabhenefiti mana makuru ekupisa kupisa kwekutanga kupisa, kunonoka kuburitsa kupisa, kushoma kugadzirwa kwemagetsi, uye zvinhu hazvibudise okisijeni panguva yekuora. process uye haisi nyore kubata moto. Kusagadzikana kwemafuta uye kuchengetedzeka kweternary lithium mabhatiri ichokwadi chinozivikanwa neindasitiri.

“Pakupisa kwe500 ° C, chimiro chelithium iron phosphate zvinhu chakanyatsogadzikana, asi ternary lithium zvinhu zvichaora paanenge 200 ° C, uye kemikari inogadzirisa inowedzera chisimba, inosunungura mamolekemu eokisijeni, uye ichaita. zviri nyore kukonzera kupisa kutiza.” Sun Huajun, mutevedzeri wemaneja weDi Battery Company, akadaro.

Nekudaro, kunyangwe maererano nekuchengetedza, lithium iron phosphate mabhatiri ane mabhenefiti asingaenzaniswi pamusoro pe ternary lithium mabhatiri, asi nekuda kwekuti simba remagetsi rakaderera pane iro re ternary lithium, makambani mazhinji emotokari dzevatyairi akawira mukunetseka kusingaite pamusoro pesimba remagetsi emagetsi mabhatiri. makore mashoma apfuura. Tichitevera, iyo lithium iron phosphate bhatiri yakanga ichiri kukundwa mune yekupedzisira mafungu emakakatanwa emutsara neiyo ternary lithium bhatiri.

Wang Chuanfu, Sachigaro weBYD Group, anozivikanwa se “Battery King”, akatanga sebhatiri. Kusati kwaziviswa kwekugadzirwa kwemotokari kuyambuka muganhu muna 2003, kutsvagisa nekuvandudzwa kwemabhatiri emagetsi emotokari kwakange kwatotanga. Kubva pakatangwa bhatiri remagetsi rekutanga kusvika pakuva imwe yemhando huru dzemotokari dzepasi rose, BYD yagara ichiisa “chengetedzo” munzvimbo yekutanga.

Izvo zvakanyatsoenderana nekukosha kwakanyanya kwekuchengetedza iyo BYD haina kumbosiya kuvandudzwa kwe lithium iron phosphate mabhatiri kunyangwe munzvimbo yemusika umo ternary lithium mabhatiri ave achiremekedzwa zvakanyanya mumakore mashoma apfuura.

Munzvimbo yemamita, hapana anopfuura makumi maviri nemapfumbamwe zvidimbu zve29 microns (bvudzi kureba 5/1 ukobvu), iyo inosangana neyakafanana chiyero seLCD skrini yekugadzira workshop.

Nzvimbo yakaoma uye mamiriro ezvinhu anongova “nheyo” yekuvimbisa kuchengetedzwa kwepamusoro kwemabhatiri eblade. Sekureva kwaSun Huajun, kuomerwa kukuru uye nzvimbo inopenya mukugadzirwa kwemabhatiri eblade inonyanya kutariswa mu “maitirwo makuru masere.”

“Chidimbu chine hurefu hunosvika 1 mita chinokwanisa kuwana kushivirira kutonga mukati me ± 0.3mm uye iko kurongeka uye nekumhanya kwekamwe-chidimbu lamination kunyatsoshanda pa 0.3s/pcs. Tisu vekutanga munyika. Iyi lamination inotora BYD Iyo yakazvimiririra yakagadziridzwa michina uye chirongwa chekucheka hachigone kuteedzerwa nemumwe munhu anoda kutevedzera. ” Sun Huajun akadaro.

Pamusoro pelamination, iyo batching, coating, rolling, kuyedza uye mamwe maitiro mublade bhatiri yekugadzira maitiro asvika padanho repamusoro repasi. Semuenzaniso, kururamisa kweiyo batching system iri mukati me0.2%; mativi ese ari maviri akaputirwa panguva imwe chete, iyo yakakura yekupfekedza hupamhi ndeye 1300mm, uye iyo coating uremu kutsauka pane imwe unit nzvimbo isingasviki 1%; iyo yekumhanyisa kumhanya ye1200mm yekupedzisira-yakafara upamhi inogona kusvika 120m/min, uye ukobvu hunodzorwa. Mukati me2μm, kuve nechokwadi chekuenderana kwehukobvu hwehupamhi-saizi yedanda chidimbu ……

Yese blade bhatiri inozvarwa kubva kusingaverengeki kutsvaga kwekukwana! Muchokwadi, hunyanzvi uye maitiro senge “pamusoro pezvakanakisa” anobva kuindasitiri 4.0-chikamu chekugadzira uye manejimendi system yeblade bhatiri fekitori.

Yepamusoro-chaiyo sensors mukati memusangano wekugadzira, maitiro, uye mitsara, mazana emarobhoti, uye yemhando yekudzora sisitimu inosangana neIATF16949&VDA6.3 control standard, nezvimwewo, inogonesa otomatiki yemidziyo yezvirimwa Hardware uye ruzivo rwemidziyo nemidziyo. Uchenjeri hwezinga rekutonga rave rakasimba “kutsigira” kwehutano hunobudirira uye hwakagadzikana hwekugadzirwa kwebheteri yeblade.

“Ichokwadi, chimwe nechimwe chezvigadzirwa zvedu zvebhatiri reblade zvakare chine kadhi reID rakasarudzika. Mune ramangwana, data rakasiyana-siyana panguva yekushandiswa kwechigadzirwa richatipawo chirevo chakakosha chekuenderera mberi kwekuvandudza kwemaitiro uye chigadzirwa chakakwana. ” Sun Huajun akati, Ford Battery Chongqing chirimwa ndiyo fekitori yekutanga pasi rose yemabhatiri eblade. Nekuwedzera kunoramba kuchiwedzera kwesimba rekugadzira, mabhatiri eblade achavhurika kune iyo itsva simba indasitiri yemotokari yekugovana, kubatsira indasitiri nevatengi, uye kubatsira kusimudzira kwepasi rose mota dzemagetsi kupinda munguva itsva.

“Nhasi, dzinenge mhando dzese dzemotokari dzaungafunga nezvadzo dziri kukurukura nezve hurongwa hwekushandira pamwe hunoenderana nesu blade bhatiri tekinoroji.” Akati.

Uye nhasi tagadzira imwe bhatiri paki yeE marines, E yatchs, E mabhoti ……
